lawn mowers are a popular seasonal tool designed to remove unnecessary vegetation in the house area. Like any other equipment, these devices periodically break down. Repairing the trimmer ignition coil is one of the most common problems encountered with gasoline braids. The ignition system itself is designed similarly on two- and four-stroke ICEs, therefore, the elimination of breakdown is performed almost identically for instruments of different manufacturers, whether it is Lux, Huter, Husqvarna or another brand. Ways to restore the efficiency of the ignition coil or replace it with a new one are in the material below.
Magneto. design and concept of work
The purpose of the ignition coil is the conversion of rotational energy into a high voltage discharge and the formation of a spark igniting the fuel mixture. In an internal combustion engine, this part is called magneto, since in it an alternating current is generated from the rotation of a constant magnetic rotor or armature.
Magneto constructively consists of two windings: high and low voltage. A capacitor with breaker contacts is connected in parallel to the latter. Whereas the findings of the high voltage winding are connected to the candle and the housing. Both of them are wound on a core, between the poles of which a rotating magnet is installed, magnetized longitudinally.
On a note! The whole design looks like a large coil mounted on a U-shaped core.
Before you start diagnosing magneto, you need to make sure that the problem is actually in this node. To do this, you need to check the entire circuit and make sure that there are no other reasons for the failure of the trimmer.
First you should carefully inspect reel for cracks and other external defects on the case. Next, you will need to examine all the elements and nodes that conduct current, and make sure that they are clean.
The next step is inspection high voltage wires. They must be intact and securely attached to the contacts, free of rust and with intact insulation.
The next step is to check candle cap. As a result of careless actions, the user often tears it from the high-voltage wire, and then improvises and creates a makeshift mount. It must be understood that any poor-quality connection in this place significantly reduces the power of the electric arc of the candle.
Then you should make sure that she candle good condition. If you fill the lawn with low quality gasoline, the life of this part is significantly reduced. In addition, it can be flooded or have a large soot that impedes work. Sometimes the candle even sticks and does not unscrew.
Next, you need to inspect circuit breaker. On Chinese-made trimmers and chainsaws, it very often breaks.
Having completed all these steps and excluding the listed nodes from the list of possible causes of failure, you should proceed to checking the coil. This can be done in several ways.
The first way that the ignition coil is checked involves the use of special equipment (stand). At home, it is not available. you can find it only in service centers.
Diagnostics of magneto using a multimeter is a solution that can be implemented on their own with such a measuring device. In this case, you must do the following.
Switch on the resistance mode on the measuring device and set the value to 200 Ohm to test the primary winding.
Connect the electrodes of the multimeter to the "mass" of the magneto and the output contact. If the winding is intact, the resistance will vary from 0.4 to 2 ohms.
Turn on a 20-com tester to perform secondary winding diagnostics. In this case, the first probe is connected to the "mass", and the second is installed in the spark plug cap. Normal values are at least 4-6 com. If the circuit is damaged, then the tester will show infinity, and in the case of a short circuit. zero.
The exact data on what the tester should be during the verification of the primary and secondary windings can be found in the instructions for using the trimmer.
If there is no multimeter, you can check the coil in one more way.
Important! The check must be carried out carefully so that the magneto does not burn out. For this, it is important not to touch the cylinder with an electrode.
For diagnosis, you need to perform the following steps:
open the cover with which the cylinder is closed;
remove the cap of the high-voltage wire from the candle without unscrewing the part itself to maintain compression;
tightly place the nail in the cap without a hat, it will imitate the central electrode of the candle;
bind the cap with the nail to the cylinder with a dielectric material so that the gap between the candle electrode simulator and the mass fluctuates from 5.5 to 7 mm (the exact distance for a particular model is recommended to see in the user manual), but the part does not come into contact with the mass;
Starter several times to start the engine, holding the ignition button in the on position;
if a spark appears, you need to consider what color it is.

A white or bluish powerful spark is normal, and a faint glimmer of an orange or yellow hue indicates a broken coil.
Often, cold magneto creates a powerful spark, but when heated due to a defect in the internal components, it does not conduct current. After cooling, the lawn mowing coils start up again and mow the grass with a fishing line or knife before heating the magneto. This is abnormal behavior, so the coil needs to be changed.
On a note! Similarly, the problem can occur when the candle is heated and cooled, so it is recommended to check the operability of both parts.
Common Problems. Causes
Faults that most often occur with magneto are typical of trimmers from different manufacturers. As a rule, this is a weak spark or its absence, as well as interruptions in this process.
If magneto flickers intermittently, check first contacts. They could be burnt or oily. Detected carbon deposits are cleaned with a file, and the oil is rubbed with suede, previously soaked in gasoline. The second possible cause of the problem is misregistration. clearance between contacts. To eliminate it, you need to set the correct distance.
If a spark appears intermittently, it may also mean that breaker lever pad worn out. To eliminate the malfunction, it is necessary to replace the lever with a new one. In addition, you should adjust the gap, as with another possible cause of failure. adjust the outline.
Breaking through capacitor may also be responsible for interruptions in spark formation. In such a situation, the replacement of the damaged part is required, since it is impossible to repair and recharge it.
Lack of sparking
If magneto does not give off a spark at all, the main reason is breakage of one of the transformer circuits (primary or secondary). To repair the lawn mower, replace the defective part. If happened primary circuit short to ground, it can also cause a lack of spark. You must fix it to fix the problem.
On a note! The broken insulation of the high voltage wire can also cause breakdowns. You can correct the situation by replacing the wiring.
Lack of sparking
A faint spark on magneto is caused by a damaged capacitor. To eliminate the breakdown, it is necessary to replace the failed part.
In order to repair a magneto with your own hands without the help of specialists, you need to know how to disassemble it, and how to change the breaker contacts to new ones.
Dismantling a magneto is very easy. First you need to remove this device from the engine and clean it, eliminating oil particles and dirt. Further, since the ignition timing unit is securely fixed, you need to unscrew the nut, and then remove the part and pull the key out of the groove. The cover is fixed on four screws. To remove it, it is necessary to unscrew and remove the fasteners. Then you need to remove the magneto rotor from the housing, unscrew the studs holding the transformer, and remove it. And to collect magneto, you need to perform the above steps in reverse order.
Replacing breaker contacts
After disassembling the magneto, it is necessary to remove the old contacts of the breaker and install the new ones correctly. To implement this, you must:
move the latch, remove the cover from the breaker;
unscrew the screw holding the connecting conductor;
remove the screw securing the breaker plate to the magneto cover and remove it;
to get the screw fixing a breaker spring;
remove the lock washer from the axis, and then the lever with the pillow assembly that it holds;
unscrew the screw securing the contact pole, remove the part from the axis.
Assemble a node with new contacts in the reverse order.
On a note! Despite the simplicity of the operation, most owners of trimmers prefer to simply replace the magneto with a new one.
Advice! Another good solution would be to provide an old ignition coil so that the seller can pick up a new part.
To remove magneto, you need to remove the plastic casing from the trimmer. On different models of lawn mowing, this process is different. Usually it is necessary to unscrew the bolts, but some gas trimmers may need to release the latches. After that, access to the coil is opened. To remove the part, unscrew the retaining fasteners and disconnect the wires.
When installing a new part, you need to competently set distance between flywheel and magneto. To do this, turn the flywheel with the magnets up, install the coil and fasten it, but do not fully tighten the screws so that there is a small distance between the parts. Next, between the coil and the flywheel, you need to put a pocket calendar, a business card or a folded four-fold A4 paper sheet, you can also use a plastic strip cut from a bottle. Such tricks will provide a suitable gap between the flywheel and magneto. A more competent solution will be to use a special template, but to acquire it for the sake of one time is impractical. Next, you need to tighten the fasteners, remove the object located between the parts, and, holding the magneto with your hands so that it does not spin, tighten the fixing screws tightly. After that, turn the flywheel and make sure that it does not catch the coil anywhere. Now you need to connect the wires and insert the candle into the cap, and then check the operation of the device.
Often, breakdowns of ignition coils are associated with a short or open winding and mechanical damage to the magneto body. This is due to strong shock, liquid and oxidation, as well as overheating. If you avoid such incidents, there is no need to worry about the integrity of the ignition coil.
Important! To prevent the regular failure of candles. one of the most important components of the ignition system. you need to refuel high-quality fuel. Bad fuel spoils these parts.
One of the magneto nodes that regularly suffer during use is high-voltage wires, through which current is supplied to the spark plugs from the ignition module. They have a high service life, but users themselves cause damage to them by inaccurate handling when replacing candles, inadvertently pulling on the wire itself, and not on the tip. Another problem that can happen to them is moisture and oxidation or damage to the insulation. By carefully pulling out the candle and avoiding the ingress of liquid into the device, these problems can be avoided.
So, the repair of the ignition coil is not very difficult and can be carried out by the user independently, but subject to the above procedure for disassembling and replacing the magneto or the breaker contacts.
Increasingly, country houses, as well as summer cottages and household plots, from places of an additional source of food products turn into an oasis of prosperity and peace. And this is not surprising, because in an era of rapid human progress associated with environmental degradation and an increase in factors that negatively affect the nervous system, I want to find my own corner where you can achieve harmony with the soul and get away from worldly fuss. For this reason, most sites no longer look like plantations of collective farms, and are converted into places that are pleasant to the eye. A lawn, alpine slides and lovely gazebos. this is what is now most often found in yards. But in order for the aesthetic component to be constant and bring widespread pleasure, these elements require constant care and maintenance of a decent level. This is especially necessary for surfaces covered with lawn and various plantings in the form of bushes. Neatly trimmed grass and bushes are a determining factor in forming opinions about the owners of the house and the mood of not only its guests, but also people passing by.
Characteristics of gasoline models
For more convenient and successful maintenance of the necessary level of landscape design of your site, you need the appropriate equipment. Various lawn mowers, and especially braids, do not always cope with the required amount of tasks. The Stihl trimmer is a product that will satisfy the needs of any, even the most demanding, owners. Ease of handling, quality and guarantee of trouble-free operation, as well as the possibility of exposure not only to grass cover, but also to various plantings make this trimmer indispensable in any conditions. To ensure quality operation in gasoline models, the 4-MIX engine is used, which defines the product as more environmentally friendly and also reduces the noise and vibration emitted by the trimmer. The gasoline model has the following characteristics:
In addition, this trimmer is equipped with automatic decompression and anti-vibration systems, which increases its service life and greatly facilitates the work.
Characteristics of electrical models
Stihl trimmer has the following characteristics:
weight is 4 kg;
the power consumed by the product is 540 V;
operating voltage is 230 V;
total length (excluding cutting product). 1.53 m;
cutting tool. mowing head.
It should be noted that this tool, both gasoline and electric, has many varieties with individual characteristics for each of them. For this reason, the above parameters are presented for the most common trimmers with average performance.

The benefits of gasoline models
The petrol trimmer trigger system is simple and reliable. Thanks to the modification of the engine, the use of this product turns into a holiday, and the monotonous work of bringing the site into the necessary form will cause only pleasure. The low level of noise and vibration will ensure that there is no need to apply additional efforts to hold this tool. Additionally, this factor is enhanced by the shoulder strap provided in the design. The belt is double, and in places of contact with the body has additional soft linings. This is especially important, since this technique allows you to use the trimmer for a rather long time and process large areas. The gasoline trimmer “Stihl” has a convenient bicycle handle, which ensures the correct amplitude of movement and quality of the result. Thanks to the design, its position changes depending on the user’s desire. Almost all control systems, including fuel supply, are located on this structural element, which allows you to use a trimmer, without being distracted by unnecessary actions. The device of the cutting element contributes to mowing absolutely any length of grass and bushes. The glasses in the kit protect the organs of vision, and the shape of the product contributes to its convenient transfer and transportation.
The benefits of electric models
Electric models allow you to quickly eliminate the disadvantages associated with the landscape design of the site. The Stihl electric trimmer, thanks to the support wheel mounted on the cutting element, can easily remove vegetation near trees, bushes, flower beds and other plantings without the danger of harming them. The convenient handle dampens a significant part of fluctuations and contribute to a reliable process. The device device provides reliable fastening of the power source and prevents it from falling into the scope of the cutting element. An extended cable (15 m) makes it possible to carry out work on large areas without the use of additional equipment.
The electric model will effectively cope with the tasks, both in a complex of applications with gasoline counterparts, and independently.
Stihl Trimmer Maintenance
Features of work
Before starting work on the site, it is necessary to assess the condition of the plant element. These steps will help to make the right choice of nozzle in cases when the cutting tool is interchangeable. It is more convenient to mow rare and soft grass with a fishing line, while at the same time, a knife is better for plentiful and dense grass. Before use, fill the tank with gasoline and added oil. If the tool is new, before the 3rd refueling it is not recommended to work at maximum speed, in order to prevent early breakdown and the need to rub parts for further high-quality interaction. It is necessary to choose the optimal position of the trimmer, and for the convenience and quality of the result, you need to divide the site into sectors. After work, the cutting tool must be cleaned of grass.
Before starting work, you need to rid the area of large elements, check the condition of the product and put on a protective mask. Do not use knives that are included with the trimmer of another brand, the cutting tool itself should not be parallel to the ground during operation. Do not use the mower, especially the electric one, in wet grass and damp weather. Pay attention to the length of the fishing line. The Stihl trimmer line should support the mowing process and not be harmful to parts of the human body, in particular to the legs. During operation, make sure that there are no other people on the site.
Summer resident I wrote. Discharge gas is necessary only when moving from one mowing area to another. When MAKING, it is not necessary, why does the engine change loads?
Private trader wrote. the need to change speed when the trimmer moves. What for?
To these questions, at one time, there was a detailed answer from Husqvarna:
1) Gas discharge is useful, firstly, because the engine is slightly cooled, and secondly, the cylinder-piston group is better lubricated (this is especially true for mowing the disk, since the disk continues to rotate and rotate the engine by inertia). the throttle valve closes, enriched fuel flows through the idle channel, and more oil enters the parts of the cylinder-piston group.
2) Gas discharge is necessary if you have an idle passage. for example, when folding grass in rolls: to the left. mow, throw grass, dropping gas, lead to the right, increase gas, start mowing to the left.
3) In principle, you can mow without ever dropping gas (if there are no idle runs and the mower is constantly under load), but watch out for the following things. a) the fishing line can wear out, two short stumps will not give resistance to the engine, it will work at maximum speed and overheat; b) any engine can overheat if kept at maximum speed (Husqvarna designers did not set themselves the task of getting into the Guinness Book of Records for the maximum time before killing the lawn mower at maximum speed), so it is better to dump gas.
Oleg_O wrote. mows and fishing line and disc
What I quickly found on the Internet (for example, =.)) Is drawn with fishing line. I did not see anything about the disc.
Oleg_O wrote. spin at full power in reverse
And why just give full speed at any move? When you start to really work, the engine will clearly understand whether you need to add speed or not. Why do you need full speed when you have three blades of grass in front of you?
Oleg_O wrote. about variable loads, how much is not good for the engine
Remember how 2T motorcycle engines work. They do not work constantly at full speed. There will be nothing with a 2T engine from the change in speed.
Oleg_O wrote. the reverse motion doesn’t seem to be very convenient to mow, the grass scatters in different directions
When working with fishing line (this is exactly what I described), chopped pieces of grass scatter in all directions (including your trousers and shoes) in any direction of movement. That is why fishing line can be well aligned lawn. If you have a disk formed by a turning line, passes at the same distance from the ground, then with your duck forward movement over the treated area of the line, it passes 2, or even 3 times. This allows you to remove the stairs, other flaws. No need to hurry.
How to change the fishing line in the trimmer and which is better to choose
Since the choice of trimmer, we examined in a previous article. then today we will tell you how to properly trim the trimmer with fishing line, and which is better to choose based on the working conditions.
After you bought a trimmer and began to use it actively, sooner or later the question will arise about replacing the fishing line, since this is the most wearing element in the tool, then intensive use of the trimmer will lead to frequent replacement of consumables.
What types of woods are
The most common type of fishing line that fits almost all types of reels # 8212; cord of round section. This is an ordinary fishing line suitable for mowing juicy grass, but it will be much more difficult to mow dead wood with it, and even more so it can’t cope with the bush.
As a rule, the diameter by which young grass can be mowed does not exceed 1.6 mm. The thicker the thread, the more coarse grass it can overcome.
Important! Choosing a fishing line for the trimmer must be guided by the instructions for your tool, since a thin thread will increase the wear of the twisting mechanism, and a thick one will overload the engine.
There are fishing lines with sharp edges in the form of an asterisk or square, this option is more suitable for mowing dry grass just due to the existing sharp edges, but its drawback is more wear and tear and is inferior in strength to round cord.
There are fishing lines with improved aerodynamics with characteristic dents, scales and notches, such a product produces less noise, but they are used only on lawn mowers, since the exit of such a thread from the reel is difficult, it is used most often with discs in which segments are inserted. The disadvantage of this product is its fragility.
Most often in gas trimmers with an engine power of more than 1.5 hp apply cords with a metal cable inside. This thread is ideal for mowing dry grass and small bushes. The presence of a core positively affects the wear resistance of this material. The disadvantage of such a cord is its price, which is significantly higher than the listed opponents.
How to Fill a Fishing Line into a Trimmer Coil
It takes about 10-15 minutes to wind the line. What is a trimmer coil? Plastic case with a cassette inside, on which there is a special hook for convenient winding of fishing line. Almost all the coils of the trimmers have a similar principle of fastening, this is the central screw-button, when pressed, it becomes possible to pull the fishing line of the required length. The photo below shows some examples of different coils for trimmers.
Video: How to Swap a Coil for a Husqvarna Trimmer
The bobbins of trimmers, the motor of which is located near the ground, have a different mount to the axis of rotation, they have two buttons on the spool located on the sides that need to be pressed, otherwise the replacement of the thread is no different from other cassettes.
The principle of proper winding of the fishing line is similar in all of the above cases, so for example, consider the standard version with two antennae.
To remove the reel with fishing line, it is necessary to unscrew the screw located in the center, but note that the thread there is left, so you have to turn it clockwise, this is done specially so that during operation it does not open under the influence of centrifugal force.
Next, using a screwdriver, disassemble the head and take out the reel, on which the fishing line is directly wound. Having measured the necessary length and folded in half, you need to fill the fishing line into the reel, removing, in the end, its ends opposite each other (for this there are special slots for fixing).
After that, it is necessary to assemble the head in the reverse order by threading the ends of the cord into two corresponding holes.
If you have doubts or it’s not entirely clear how to charge the fishing line to the trimmer, we recommend watching the video: how to wind the fishing line into the lawn mowing properly. In this video, the instructor will open the trimmer head in steps, measure out the required amount of fishing line, usually from two to four meters, and demonstrate assembly and installation on the trimmer.

How to refill a fishing line in a trimmer so that working with it does not tire
Many summer residents use a trimmer. a scythe with an electric or gas engine to control weeds. It is convenient when working in places inaccessible to the lawn mower: at fences, flower beds, houses, in the garden on narrow aisles, and can cut small branches. The main element of this wonderful technique is an ordinary fishing line wound on a reel. The device is simple, but the cutting part wears out quickly, requires replacement. And the question of how to fill the line in the trimmer worries many owners of cottages.
Briefly about the fishing line
Depending on the models of the tool, the thickness of the fishing line is 1.2-4 mm. There are such configurations:
round. the most durable;
curly. for soft grass;
twisted or notched. for thin grass;
professional, not suitable for all instrument models.
When replacing the cutting thread, you need to choose the one that suits your type of trimmer. Preference should be given to specialized. Before filling the fishing line into the trimmer coil, it is better to soak it for half an hour in water. Then it will become more elastic and stronger.
How to quickly remove a coil from a tool
Before the thread is wound on a bobbin, it must be removed. over, the removal methods depend on the features of the tool. On trimmers with a motor near the ground, the spool has two side buttons, when pressed, a part of the housing is separated along with a thread winder.
On instruments with a bent rod, the lamb on the fixture is moved counterclockwise; having disconnected it, they remove both the bobbin and the spring inside it. On trimmers with a direct bar, fix it with a screwdriver, rotate clockwise and remove. Then the device is disassembled either using latches, or by moving its parts in different directions. The spring is taken out of the coil.
Refueling the fishing line with a trimmer
The main question is how to wrap the fishing line on the trimmer coil, fixing it securely there?
In the case of a device with one antennae, up to four meters of fishing line is unwound, inserted into the hole inside it, fixing the fishing line, one of its ends and moved in the direction indicated by the arrow. The edge of the thread is fixed in the groove inside the bobbin so that when it is assembled, it does not unwind. If there is no groove, then this free end is fixed with a finger. Then the coil is assembled.
How to refill the trimmer coil if it has two antennae? In this case, check how many grooves are on it. one or two. In the first case, both antennae are sent to the common groove, if there are two, then each of them. in its own. 2-4 meters of thread are passed through the hole so that the free edges of the thread are the same length, and twist the bobbin in the direction of the arrow. The ends of the thread are inserted into the grooves or held with a finger, assemble the device and attach to the trimmer.
In a spool with two grooves, the same piece of thread is folded in the form of a loop, sent to the groove between them and the ends are wound at the same time. Then repeat the previous assembly. With semi-automatic winding, the bobbins act as follows. The fishing line is passed through the hole inside, its ends are fixed in the holes on the body, collect it and press the button. In this case, the thread is easily wound in the right direction.
It is important to remember that the cutting surface must be protected from solid objects so that it does not wear out. Otherwise, it will be necessary to constantly stop and, having removed the bobbin, replace the spent fishing line. Let your work be not tiring and bring joy!

According to the device, the shampion trimmer resembles its old-time manual counterpart. the braid: a straight or slightly curved rod with a handle for guiding the movement of the braid, at one end of which there is a working device. a trimmer head, and on the other. the engine. The energy from the engine to the cutting tool of the trimmer head is transmitted through a shaft or cable located inside the rod. To ensure that the pigtail’s legs are protected from damage by the cutting tool, the trimmer head is equipped with a protective cover.
The functionality of the trimmer is determined by its working tool. the trimmer head. By changing the nozzles of the trimmer head, you can adapt the campaign trimmer to perform a wide variety of tasks.
For mowing or mowing grass, cutting surfaces are used. fishing lines or knives. Fishing lines protrude from the rotating drum 15-25 centimeters on either side of the center, which provides a mowing width of up to 45-50 centimeters, and cut plants at high speed, like a razor. Nozzles with fishing line are convenient to use when processing complex terrain, with stones and protruding tree roots: due to their elasticity they will not break and will conscientiously remove all annoying weeds and cut the grass. If you change the nozzle to a shampion trimmer, the trimmer can become a brush cutter: plastic or metal knife-cutters trim the crown of the hedge and mow dead wood or young talnik.
Additional nozzles can turn a shampion trimmer from a lawn-mowing machine into a real small-scale mechanization tool: special nozzles allow cultivation of the soil, and in winter a shampion gas trimmer can serve as a snow blower.
Depending on the type of engine hampion. the trimmer can be electric or gasoline.
The Campion electric trimmer is a very environmentally friendly tool, it is launched with a simple click of a button, it produces almost no noise and does not pollute the surrounding nature.
The trimmer with an electric motor is lighter than a gasoline one (after all, it does not need a fuel tank) and is used to regularly mow soft lawn grass, but thick stems of plants or hard dead wood cannot do it. The Campion electric trimmer must be connected to a power source. For this, a long network cable is used, which fetters the freedom of movement of the mower and requires certain skills in managing this garden tool. And, of course, like any power tool, the hampion electric trimmer cannot be used in wet weather.
These disadvantages are deprived of the shampion gasoline trimmer: it can work in any weather, mow dewy grass, and does not limit the operator’s freedom of movement. The price for greater mobility, power and functionality is the increased weight and the need to replenish the supply of fuel gasoline-oil mixture, ensuring the operation of a two- or four-stroke internal combustion engine.

How to wind the line on trimmer coil, if you haven’t done it before. Learn from the article how to win line to trimmer coil
Many, having developed a factory fishing line on a trimmer not so long ago obtained, try to rewind the latest, but they cannot, because they do not know how to wind the line onto the reel spool (bobbin) correctly. As if the annotation is, but still does not work. Let’s try to deal with this issue in this article.
So that win line, it is necessary, for starters, to remove the coil from the trimmer so it will be more convenient. Cord for trimmer rating. The removal method will depend on the type of trimmer.
Remove the coil from the trimmer
On small electronic trimmers with the bottom position of the motor (when it is when working near the ground), the coil usually has two buttons at the edges. Click on them and disconnect one half of the coil body from the 2nd, which remains on the trimmer. Together with the first half, the inner part, on which the fishing line is wound specifically, is removed. Trimmer carburetor needle adjustment. When disassembling, be careful: inside there is a spring that can fly out and get lost.
On electronic and petrol trimmers with a straight rod and a reducer at its end (you can also install a knife on the trimmers besides the fishing line), we look for a hole under the coil, insert a screwdriver in it, for example, rotate the coil quietly until the screwdriver penetrates even deeper and the coil will lock.

Now, having removed and disassembled the coil, we proceed, in fact, to winding.
If your coil is designed to work with only one antennae, then everything is very simple. It is necessary to rewind 2-4 m of fishing line (depending on the size of the reel), find the hole fixing the fishing line on the inside of the reel, stick one end of the line there and begin to reel the line in the direction opposite to the direction of rotation of the reel on the trimmer. On the inside of the reel, they usually indicate an arrow, in which direction to wind the line. After winding up the fishing line, we leave its small piece unmotivated to expose it. Interskol trimmer motor device. We fix this piece in a special groove located on the inside of the reel and created so that the fishing line does not unwind at the time of collection of the reel. If there is no such groove, then you will have to hold the fishing line with your finger to prevent it from unwinding during the upcoming collection of the reel. Next, take the outer part of the reel and thread the outer piece of fishing line into the existing hole, collect and put the reel back on the trimmer.
If coil created to work with 2 antennae, then do the following.
If there are 2 grooves, we fold the piece of fishing line 2-4 m long in half, insert the loop obtained at the bend point into the groove between the 2 grooves, and immediately wind both ends of the fishing line each in its own groove. Refueling fishing line into the reel of the trimmer video. Subsequent acts are similar to the previous version.
There are still reels in which the line is threaded through the through hole on the inside, the ends of the line, without winding, are completely passed through the holes on the outer casing of the reel, the reel is assembled and the button is pressed, which is usually pressed to release the line through the extent of its wear.
That’s all for the matter. Good winding!
How does the trimmer work?
The principle of operation of such a device is that the grass is mowed by a special fishing line mounted on a rapidly rotating head. The number of revolutions per minute can reach 8000. For a short time, the fishing line becomes unusable, or rather, it is erased. Then the summer residents the question arises: "How to fill the fishing line into the trimmer coil"?
Types of woods for trimmer
First of all, in order not to resort to frequent replacements, it is better to use a denser fishing line. The number of its types and manufacturers is simply amazing. The main parameter of the fishing line for the trimmer is its diameter. It varies from 1.6 to 3.2 mm. The most common type is a 2 mm fishing line. However, it must be selected depending on the type of trimmer you have.
There are several options for the cross-section of the line. So, it can be round, square, in the form of an asterisk with sharp edges. The most effective is the last option. However, it should be used only on powerful braids and you need to know how to fill the fishing line into the trimmer coil. Therefore, we can conclude that the more powerful your lawn mower, the fishing line should be thicker.
Such a process as winding fishing line on a trimmer is not complicated, but has its own characteristics. First you need to choose the right fishing line, the diameter of which is registered in the passport of the device.
To begin, unscrew the cover of the coil. Be careful, as the thread can be left and right. The left-hand thread is necessary so that the braid head does not unwind during operation.
Refueling the fishing line with a trimmer
Before filling the fishing line into the trimmer coil, measure 5 m from the skein (as many fishing lines are installed on the trimmers on average). Then fold it exactly in half to find the middle. The resulting center must be inserted into a special slot, which is located on the coil. After that, wind the fishing line in the direction of the arrow that is on the head.
There are such models in which the place of winding is divided into two halves. Therefore, one is often wound clockwise, and the second against. After winding the fishing line completely, its ends are threaded into special holes. The cap is put on top of the head.
From the above it follows that the process of replacing the fishing line itself is not complicated. Having performed such a manipulation as winding fishing line on a trimmer reel several times, you will bring this process to automaticity. The only thing is to constantly monitor the condition of the fishing line, in order to avoid its rupture at the time of work on the site, when the spare skein may not be at hand.
Now you know how to fill the fishing line into the coil of the trimmer, and you can do it yourself without much effort!
Types of Trimmer Heads
The grass mowing head is a cylindrical body in which a reel (bobbin) with a fishing line (cord) tucked into it is inserted. This design can be installed on both gasoline and electric trimmers. The heads differ in the method of filling and feeding the cord and there are 3 types.
Automatic. Cord feed is performed after the user reduces engine speed. Although automatic feeding of fishing line is convenient if large volumes of work are performed, such bobbins have one drawback. high thread consumption.
Based on the above, semi-automatic bobbins are the best option. It should also be borne in mind that the coils for the trimmer are single-string (used only for trimming grass) and double-string, which are used to mow tall grass and small, with thin stems of shrubs.
How to remove and disassemble the coil
Before starting the process of replacing the cord, users of trimmers need to remove and disassemble the coil. Consider how to do this.
The mowing head of the trimmer consists of several parts: casing, springs (not on all models), bobbins with cord and covers.
Attention! Before proceeding with any maintenance of the electrical unit, it must be disconnected from the mains.
In trimmers, 2 options for attaching the mowing head are most often used.
Option number 1
To remove the trimmer head, you will need it complete disassembly.
Option number 2
In this embodiment, the head is screwed onto the gear shaft. To take it off, you need this lock the shaft. To do this, in such trimmers, for example, in Huter and Champion devices, a hole is provided through which you can insert either a thin screwdriver or a metal rod.
So, to remove the bobbin, follow 2 simple steps.
Insert a screwdriver into the hole and lock the shaft.
Grasp the head housing and start twisting it clockwise. Turn in this direction for the reason that the thread cut on the shaft is left.
Fishing line winding algorithm
Depending on which trimmer model is used, the type, thickness and length of the fishing line are selected. The diameter of the cord can be from 1.2 to 4 mm. It is not difficult to guess that the thicker you fill the cord, the more rigid and thick grass it can cut.
In most cases, a universal fishing line with a diameter of 2 mm is used.
There are 3 ways to find out what diameter of fishing line can be used on your mower.
View information about the thickness of the cord in the instructions for the device.
Look at the bobbin itself. It can be marked with information about the possible diameters of the fishing line.
Insert the fishing line into the outlet. If it easily passes into it, then a cord of this diameter can be used.
The line is wound on a reel located in the mowing head. Therefore, you must first open it (this was discussed above). There are 2 ways to wind the cord.
In order to correctly determine how many meters of fishing line is needed for a particular reel, it is necessary to wind it on a bobbin so that the coil does not exceed the diameter of the sides. If the fishing line peeks over the edges of the reel, you cannot insert it into the casing. After you have decided on the length of the material, it must be loaded into the bobbin, so do the following.
Necessary fold the fishing line in half, so that one end of it is 10-15 cm longer from the other.
Please note that the bobbin is divided into 2 parts by the central side, from which charging begins. Find a groove on it and insert a cord bent in half into it, with a little effort.
It is very important to identify, in which direction is the fishing line wound to the reel. If you look closely, you can find an arrow on the bobbin or an inscription with an arrow indicating in which direction the winding should be carried out. There are times when there is no arrow on the reel. In such a situation, you can look at the arrow drawn on the mowing head and wind the cord in the opposite direction.
Winding should be carried out carefully, coil to coil, with maximum thread tension.
After the laying of the cord is completed, you will need to first fix the short end of the fishing line by inserting it into a suitable diameter groove on the side of the reel.
The second end, the one that is authentic, is mounted in a groove on the opposite side of the bobbin.
After fixing the fishing line, cut off its ends, leaving allowances of about 10 cm.
Next, you need to install a seasoned coil in the mowing head. To do this, by inserting and pulling the thread into the outlet openings of the head, place the bobbin in the casing, and then, after applying the required force, pull the fishing line out of the fixing grooves and tighten it.
Now you can put on the cover and fix it with latches.
In some coils, a second method of securing the cord is provided: 2 pieces of thread can be charged, instead of one folded in half. Replacing the fishing line occurs according to the following algorithm.
Video: How to Wind a Husqvarna Trimmer Coil
Before changing or charging a new thread into a spool, determine how many meters it will be required in the manner described above.
Bend one end of the cord in the form of a hook.
Locate the hole at the bottom of the bobbin to secure the fishing line, and insert the end of the thread bent in the loop into it.
It is required to wind the cord according to the direction of the arrow to the required level not exceeding the diameter of the coil.
Do the same for the second bobbin slot.
Assembling the head is no different from the method that was given when refueling the bobbin was considered with a doubled piece of fishing line.
For Shtil lawn mowers There is a very simple and quick way to replace the fishing line without disassembling the mowing head, which you can familiarize yourself with by watching this video.
The ends of the cord sticking out of the holes in the casing can be cut to the required length already when the part is installed in the trimmer. There are two ways to do this:
turning on the trimmer (during rotation, the ends of the fishing line are cut off on a knife fixed for this purpose on the protective cover);
by cutting off the excess ends with scissors so that they do not touch the housing body.
The second method is used if it was necessary to put a cord of large diameter, and a cutter cannot shorten it.
If the thread was charged into the mowing head, but the length of the protruding ends of the cord is insufficient, then they must be lengthened before starting the machine. this applies to the head with manual adjustment. However, there are cases when using a semi-automatic mowing head, when due to the insufficient length of the protruding ends of the cord, they do not automatically extend. In this case, it is necessary to turn off the unit (it is absolutely necessary to pull the plug out of the socket on the electric apparatus), manually press the button located at the bottom of the part, and pull out a little fishing line. After this procedure, the cord will again be able to extend due to centrifugal force, if you set the maximum spindle speed.
No matter what thickness you put the line, you should remember: in order not to interrupt the work and not change the cord, you should avoid areas where the working tool can touch hard surfaces (stones, curbs, thick dry branches, etc.).
What can be used instead of fishing line
Many users of trimmers are wondering: what can replace the default cord used in this kind of apparatus? They begin to conduct unsafe experiments by installing metal or copper wire, metal cables or strings, as well as ordinary fishing line in the mowing head.
If set instead of fishing line metal cable, then the trimmer turns into a dangerous device not only for the user, but also for others. This fact is explained by the fact that during operation of the unit, the steel cable will gradually work, its ends will unravel, and small pieces of wire will fly apart in different directions at high speed.
A similar thing happens when using steel or copper wire, only with the difference that the pieces that come off will be larger and can cause serious injury.
And if you accidentally hook your own or someone else’s foot while operating the machine with a steel cable (wire), then a strong and deep cut of the tissues, and in some cases amputation of your toes, is provided. It is not in vain that the manufacturer uses nylon for these purposes, since it is quite light and durable, and when detached it does not fly away and cannot cause injury.
Use fishing line in the trimmer instead of the standard one, of course, it is possible, but this will add you unnecessary trouble, because it wears out quickly, breaks, mows slowly and is not suitable for cutting hard grass. In addition, during the work, a lot of time is lost in order to replace a broken tool more than once.
In practice, the installation of an ordinary fishing line is justified if the user is going to mow the grass near the fence, especially if he is from a netting net. In this case, in order to protect the standard, and sometimes expensive cord from wear, it is changed to a fishing line, which is not AL-KO. Usually, in order to change the cord to the fishing line, it needs to be selected with the greatest thickness. 2-3 mm.
Replacing fishing line with a disc or knife
When refining a garden plot, park areas and other places where it is necessary to mow various kinds of plants, it is often necessary to change the cutting tool in the trimmer. This is dictated by the fact that the standard cord installed in the mowing head can only cope with herbs. But when a shrubbery or young shoot of trees appears on the way of the worker, the line cannot cope with such a task, and it needs to be replaced with a more effective cutting tool.
Manufacturers of trimmers provided such situations, and supplemented their products with a mass of nozzles in the form of knives with several “petals” or in the form of disks similar to circular saws.
If you replace the fishing line with a knife with several “petals”, then with such a tool you can mow both tall grass and plants with thick and dry stems. And changing the fishing line to disk, the user has the opportunity to lawn mowers to cut shrubs or small trees.
Knives and wheels are installed according to the following algorithm.
The first step is to remove it by locking the shaft, the mowing head (turn clockwise) or the nut with the boot if the unit has not been used yet.
Set the saw or cutting knife so that they are put on a small ledge (bushing).
Install the fastener cover on top of the knife and screw the nut onto the shaft (counterclockwise).
Tighten the nut (counterclockwise) using a pipe wrench.
For a better understanding of the tool change process, you can watch this video.
Fishing line problems
Users of trimmers, both gasoline and electric, sometimes have problems with the cord. “Advanced” owners of mowers can easily cope with the difficulties encountered, understanding why this is happening, and for beginners, this is a problem that does not have a rational explanation. But in fact, everything is solved quite simply. The most common problems that happen with fishing line are as follows.
If the line is often torn, the following reasons can cause it:
stones, small branches and other solid obstacles come across in the grass;
the user mows the grass right next to the fence, and if it is mesh, it breaks the “antennae” even faster;
poor quality of the cord (it is recommended to purchase high-quality);
the outlet openings in the mowing head are worn out, due to which the fishing line is erased against the sharp edges of the bushings and breaks off (a complete replacement of the part is required).
High cord consumption
Basically, a cord ends quickly if often pounding the ground with a semi-automatic head or push it down hard. The reel is unlocked, and the fishing line, lengthening, is cut with a knife. Another reason that the cord ends quickly is the improper use of the machine with an automatic head: when mowing, the user often drops engine speed. But as we remember, the automatic head is designed so that it is with each decrease in speed that a new portion of fishing line is fed, so it is quickly consumed.
The thread does not hold
It happens that the thread is unwound if in a semi-automatic head the spring has loosened. The fishing line is constantly extended and trimmed with a knife mounted on the casing, which increases its consumption. To check this, remove the cover and turn on the unit. If the fishing line “climbed”, then you need to replace the spring.
Fishing line crashes
The reason that the cord unwinds after starting the unit can also be the weakening of the spring inside the head. In addition, there are times when the mowing head scatters when the unit is turned on, and the spring installed in it is lost. Inexperienced users do not notice the absence of a spring and assemble this unit without it. Therefore, the cord does not hold, and flies out under the influence of centrifugal force.
The cord does not feed, the coil does not spin
An automatic or semi-automatic head should feed the line without stopping the unit. But if it does not come out, then the reasons may be the following:
incorrectly wound fishing line in the reel, because of which the latter does not spin;
the cord is wound unevenly, and the thread can get stuck between turns (the thread should be wound carefully, turn to thread, without distortions);
too short ends of the thread come out of the holes, as a result of which there is not enough centrifugal force to extract them, and the fishing line is not supplied (it is recommended that the cord length is always adjusted before starting the unit, pulling it slightly);
the fishing line stuck together (to be discussed later).
The thread sticks together
This trouble is most often due to use of low-quality cord. When the machine is operating, the trimmer head heats up, and the poor-quality fishing line in it melts, sticking together. Also, sintering of threads occurs when a fishing line meets a solid obstacle. In this case, a sharp braking of the cord occurs, after which it is pulled into the head, where it is attached. Some owners of the units recommend lubricating the cord with mineral oil or spraying it with silicone spray after winding on a bobbin. Others advise winding less thread on a bobbin. But it is better to immediately buy a quality product, in the manufacture of which the manufacturer took into account the head overheating factor, and the thread will not stick together.
Spinning reel models and winding types
Any fishing rod or spinning rod has a reel. There are 3 varieties of fishing reels. For each of them a special type of winding fishing line is provided. Since the reels have a different design, we will analyze how the line is wound on each of the listed types.
The main element responsible for the winding of the line is the logger. This is a metal loop with a roller, which makes circular movements around the spool when working with the handle. During the first turn of the spool, the logger winds the line in one direction, for example, in the upward direction, and in the second turn of the line, the line has the opposite laying direction. As a result, the fishing line spool is located crosswise.
Installing fishing line on an inertialess reel has several methods. Each type of coil has its own winding method.
This is the so-called taper of the winding:
Straight cone. Toward the front side of the spool, the thickness of the stacked fishing line is reduced.
Inverse cone. The thickness of the fishing line gradually increases in the direction of the front edge of the spool.
Chaotic winding. Fishing line is wound arbitrarily. This method of winding is inherent in inexpensive Chinese products.
“Straight cylindrical” winding is obtained by installing two shims
Initially, new coils are configured for cylindrical styling. Then, as necessary, each angler adjusts the styling method "for themselves." Taper adjustment is carried out thanks to special washers located on the axis of the spool. So, if jerking baits are used for fishing, then reverse cone winding is used. In this case, the washer is replaced with a smaller one or removed altogether.
The line should be wound around the multiplier so that there is a gap of about 1-2 mm to the edges of the spool. Since backing of this type is not used in coils, it is necessary to accurately calculate the amount of fishing line for winding. That is, it should not be enough.
You can fill the cord or fishing line in such a coil in the following order:
The end of the line is threaded through the logger.
The fishing line is attached to one of the holes of the movable spool. You can also fasten the fishing line with a loop by wrapping the fishing line around the spool axis several times.
The reel is attached to the rod.
The line is passed through the right ring.
The friction brake is tightened.
It remains only to quickly reel the line on the spool, and then put on a leash. In order for the turns to fit tightly, it is necessary to create some tension on the fishing line.
How to create a special knot for tying fishing line on a spool
The fishing line is laid most easily on an inertial-type reel. It is attached to the spinning reel by a simple knot-eight or a double loop. Next, the desired amount of fishing line is wound. In the process of winding, you need to make sure that the turns lie evenly. Provide tension to the fishing line. The easiest way to do this is with an ordinary book. A fishing line is passed between its pages, which press it, creating the necessary tension.
How to wind a fishing line
We will analyze step by step how to wind an existing fishing line onto a spool of a reel. First you need to ensure the free flow of fishing line from the reel. To do this, you can use a screwdriver, a piece of thick wire or a regular pencil. It would be better if you do this work with an assistant. He will hold the makeshift axis with the bobbin, and you will reel the fishing line on the reel. The winding pattern is as follows.
You need to thread the line through the passage spinning rings. You need to start fishing line from the upper ring. Then the fishing line must be tied on the spool. You can fix the tip of the fishing line with a regular noose-loop, or wrap it with adhesive tape or electrical tape. Reliable fastening is especially characteristic of a braided cord, as it tends to “slip through” at the beginning of the winding. After that, you can wind the line on the spool, lowering the logger.
In the process of winding, it is necessary to ensure that the line lies with a slight tension. This will prevent the formation of loops.
At the final stage, all the gear should be adjusted. You need to attach a leash to the main fishing line that will be used for fishing. You can fix the leash to the main fishing line in different ways. Most often, anglers do this with a winding ring and carbine. The ring is fixed on the main fishing line, and the carabiner is attached to the leash. The bait leash can be replaced at any time.
The process of winding fishing line on a reel
What is backing?
This term applies only to non-inertia reels due to the specific winding of fishing line on them.
It often happens that the fishing line on the spool is not wound enough. For example, the spool is large, or the line is too thin. It seems that they used all 100 meters of fishing line, and 5 or more millimeters remain to the sides of the spool. In this case, the so-called backing is used, that is, the winding of the additional fishing line. Such a winding should be located at the very bottom of the spool. It performs only auxiliary functions, without taking part in the fishing process. But how to put it at the very bottom? To do this, remove the fishing line from the spool, and then install it on the other side.
To replace, unscrew the clamping front nut and then remove the spool with fishing line from the reel. Instead, an empty spool is mounted on the reel. The line is rewound from one spool to another. Thus, the winding line is at the very bottom of the spool. If you do not have a spare spool, then use an empty reel from under the fishing line.
Winding reels using backing
How many fishing lines to reel
How much fishing line do you need to recharge on a spool of reel? Experienced anglers always winding fishing line is not as long as it will be necessary for casting, but with a large margin. This is necessary to insure against possible cliffs. Also, if a braided cord is used, at the end of the season you can swap the sides of the cord by rewinding it to the other side. This will save costly consumables.
Usually on each reel the quantity of fishing line of a certain thickness, which the spool can accommodate, is indicated. Usually, even a few values are written. For example, "0.25 / 200 0.30 / 150 0.40 / 100".
Tip: so that during the casting process the line does not self-reset from the spool of the inertialess coil, do not bring the winding to the very edges of the spool. It is recommended to leave a gap of 1 to 3 mm. A gap of more than 5 mm will create difficulties with casting range.
Spinning line from the popular manufacturer Shimano
If you want to wind a certain number of meters, you need to calculate how long the fishing line is 1 turn of the spool. After that, you can roughly calculate how many revolutions of the handle you need to do to wind a certain amount of fishing line or cord. But keep in mind that the number of revolutions of the reel handle never matches the number of turns of fishing line on the spool. For example, in most inertialess reels, the line will make 5 turns with one turn of the handle.
We figured out the issue of winding fishing line or braided cord on a spinning reel. Guided by this information, you can easily put the right amount of fishing line on the spool. If necessary, you can use backing if the fishing line on the spool is not enough. If everything is done correctly, then you can only rejoice at distant and accurate casts.
Grass trimmers are an indispensable tool in the adjoining areas, which allows you to quickly remove unwanted weeds. But, like any other technique, they break down over time. To repair or set up a garden tool, you need to know its device, the principle of operation, as well as the nature of typical malfunctions of a trimmer working both on gasoline and on electricity.
Principle of operation and trimmer device
As you know, modern grass trimmers are gasoline and electric. Representatives of these groups are distinguished by their design and operating principle, and also have some operational features.
Gas scythes are produced by brands such as Husqvarna, Huter, Champion, etc. Despite the variety of brands, the design of these devices is the same and fundamentally no different. So, an engine is placed on top of the lawn mowers, a fuel tank and a starter for starting the tool are installed next to it. There is also a switch that regulates the position of the air damper. This allows you to quickly warm up the engine at low air temperature and simplify its starting. Further from the engine comes a rod with a rigid or flexible shaft for transmitting rotation from the motor to the gearbox. The bar can be solid or collapsible, consisting of several parts.
The device of the lawn mowing rod is as follows. Firstly, there is a handle on it, which has a different shape and is adjustable for the convenience of the employee. Secondly, on the stand (and more specifically on the holder) are placed control keys connected to the drive with a special cable. Thirdly, in the lower part of the rod there is a reducer transmitting movement from the shaft to the spindle with a cutting unit. As a rule, the cutting part is a cord (reel) with fishing line or a metal knife. To protect the user, a protective cover is mounted above the mowing head with a string or a disk.
The principle of operation of the gas trimmer is as follows:
using a starter, the worker starts the engine;
rotation from the engine crankshaft through the shaft installed in the rod, enters the gearbox;
movement from the gearbox goes to the spindle with a cutting unit;
cutting tool, rotating at high speed, cuts off the shoots.
Important! To increase or decrease the spindle speed, you need to press the throttle button harder or harder.
Popular instruments of this type include the Hummingbird Partner trimmer, Patriot equipment, etc.

Electric group trimmers. network
Electric trimmers are very easy to use and differ from the lawn mowers by the type of drive used. an electric motor is installed in them. The device of the electrohair “Stihl”, “Soyuz” or another brand has the following form. The main part is a body with an electric motor. It has power and lock buttons against accidental start-up, and a power cable with a plug. A detachable rod is attached to the body, equipped with an adjustable handle that allows you to choose the best grip for the mowing, and mount for the shoulder strap. For ease of storage and transportation, the bar is disassembled into two parts. The trimmer coil, consisting of a bobbin with fishing line, a protective casing and a knife for cutting the string to the required length, is attached to the bottom of the rack. The rotation of the bobbin from the electric motor transfers the flexible shaft.
Electric trimmers are available with top or bottom engine. In the first case, this is a technique with a power of up to 1.4 kW, which is capable of cutting tall and wet grass, as well as a thin shrub. Such devices are equipped with fishing line or metal knife. While the devices of the second type have a lightweight mechanical part, since they do not need a gearbox and shaft to transmit rotation from the engine. Their cutting unit is located on the motor spindle, which significantly increases the practicality and reliability of the design. However, such devices have a lower number of revolutions and are able to cope only with young and not very dense shoots.
To start working with the electric braid, you need to connect the tool to a power outlet and press the "Start" button on the housing. This will start the engine, and the rotation from the rotor will go to the gearbox directly or through the shaft. Upon reaching maximum speed, the tool can be used to mow grass.
Important! Unlike lawn mowing, with trimmers (especially with a lower engine) it is forbidden to work in the rain or to clean wet grass. Failure to comply with this rule may result in electric shock.
Electric group trimmers. cordless
There is another type of electric trimmer. battery. These tools are low-power and are not designed for continuous operation (on average. 15-25 minutes, when fully charged in 3-4 hours).
Advice! For battery models, it is recommended that you purchase a second battery, as the first will need to be recharged regularly.
The advantage of this type of technology is mobility and low noise level, therefore it is used in territories where it is not allowed to make noise. These are hospitals, hotels, sanatoriums. In addition, the use of these trimmers is relevant in cases where the electric cable greatly interferes with work and movement. However, before each inclusion, you need to check the battery charge.
General design features
Gasoline and electric trimmers have different designs, but in the general case the principle of operation is identical. a strongly rotating fishing line or a knife cuts grass. Therefore, the cutting side, gearbox and boom are structural elements that are the same for all types of hand mowers.
Typical malfunctions of gasoline trimmers
The design of gasoline trimmers is more complicated than electric trimmers, so they have more damage.
If there is no spark at the start of the engine, or there is a spark, but weak and insufficient to ignite the fuel, this indicates a failure in the ignition system. To eliminate it, you need to check the magneto. Sometimes it is necessary to replace the high-voltage wire, if it is broken, or to clean the contacts. Also, the cause of the spark disappearing is a damaged candle cap. In some cases, the problem occurs if the mixture fills the candle, or carbon deposits appear on it. On cheap Chinese lawn mowers, the engine sometimes does not start because the circuit breaker is broken.
Often the problem is not in the details themselves, but in the unexposed gap between the ignition coil and flywheel magnets. In this case, adjustments must be made. If this procedure is not performed, an early or late ignition of the fuel occurs.

Important! As a result of non-compliance with the recommendations for adjustment, the engine runs at low power or does not work at all, the starter breaks, the cord breaks, etc.
When diagnosing the fuel system, the presence of a combustible mixture in the tank, as well as its quality, is first checked. It is prepared according to the user manual, it is forbidden to change the proportions. Also, do not make the mixture with a margin. during storage, it changes its properties and subsequently harms the equipment.
First you need replace mixture in the gas tank and restart the engine. One of the signs of poor quality fuels and lubricants. the trimmer does not switch speed and cannot gain momentum, and also stalls, regardless of how it was started. to cold or after warming up.
If the device starts up poorly again, you need to inspect the candle channel. Perhaps it got a combustible mixture. This is due to improper use of the tool: at start, the air damper is set to the off position, but after the engine is started, it is not put into the on position, which causes the engine to stall. The next time you try to start the engine, throw a candle with fuel, after which starting the device becomes impossible. To eliminate the problem, the part is twisted and thoroughly dried, since only a dry candle can be installed. You also need to drain the fuel from the candle channel, remove carbon deposits from the electrodes of the candles and when installing correctly set the gap between them.
Air filter. Another possible reason for the failure of the trimmer. If it is clogged with debris, air does not pass into the combustion chamber and the fuel does not ignite. The part is changed or thoroughly washed and dried. If oil is found in the air filter, it is washed with gasoline and dried for several hours.
Fuel filter also subject to verification. It cleans the fuel mixture from garbage. Its clogging leads to the fact that gasoline does not enter the cylinder, and the trimmer stalls. It is necessary to remove and clean the fuel filter, if necessary. change to a new one.
Breather. This is a non-return valve that allows you to equalize the pressure in the gas tank. If it is clogged, a vacuum forms in the fuel tank and no fuel enters the carburetor. You can verify this by removing the hose from the tank to the carburetor. If gas does not leak, the valve is clogged. There is a breather on the gas tank cap, sometimes on the fuel tank. The part must be disassembled and thoroughly cleaned.
This lawn mowing unit breaks due to low-quality fuel, accumulated dirt in the chamber, as well as a deformed air filter. Parts such as membranes, inlet needle, seat, strainer, adjusting lever, flaps, etc., may become clogged or broken. Diagnosis of the device and subsequent cleaning or repair are required.. In some cases, carburetor adjustment is required.
If the lawn mower stalls when the user presses the gas and increases the engine speed, this may indicate a clogged exhaust system. This is due to the large amount of burning released during the combustion of oil, which is part of the fuel mixture. To eliminate the problem, you need to clean the muffler and related parts.
Important! The only way to avoid a breakdown is to properly observe the proportions of oil and gasoline when preparing the fuel mixture.
The purpose of the starter is to assist in starting the lawn mowing engine. The main malfunctions of this node are: breakage of the cord and breakage or exit from the spring hook. To eliminate the failure, the starter is disassembled, the cord is replaced with a new one, and the spring is returned to its place, or if it is damaged, install another.
When diagnosing a piston group, the compression must first be checked. If it is not suitable, the engine will not start. Normally, it should be over 8 kg / cm 2.
On a note! On some engines there is no idle, therefore, with an indicator of 8 kg / cm 2 they stall, since the fuel mixture does not pump up. So, if the lawn mowing does not swing above the recommended value, you need to check the piston, cylinder and rings.
Another possible reason for low compression is a poorly fixed carburetor. If gasoline drips during operation, this also indicates that you need to tighten the mount of this unit.
One of the possible malfunctions of the cutting blade is the cassette cover is displaced or stuck. This is due to axis misalignment or the installation of an unsuitable mowing head. As a result of this, rotation is hindered, the load on the motor increases, and it overheats.
If the cutting blade does not rotate, the inspection of the assembly depends on the design of the rod. For a curved shape, you need to inspect the sleeve and the rod itself, and for a straight one. the shaft, gearbox and clutch. All connections between parts must be intact. The check is carried out only if the trimmer motor is working.. Sometimes confusion occurs, and users think that the problem is with the cutting unit, but the motor is actually defective.
If the cutting part of the trimmer is constantly spinning at idle of the engine, and an uncharacteristic metal rattle is heard. these are signs of a malfunctioning clutch. Typically, the cause is a bursting or extended spring. If slipping is added to this, then the pads are also faulty.
On a note! To fix the trimmer, the clutch is disassembled, inspect the spring, bearings and block. Defective items should be removed and replaced with new ones.
Drive shaft and rod
If strong vibration occurs during operation, this indicates the absence or lack of lubrication on the shaft inside the rod. In this case, even an anti-vibration system will not help. shock absorbers located between the bar and the motor. To fix the problem, it is necessary to disassemble the braid and lubricate the shaft. And in order to avoid another manifestation of such a breakdown, you need to regularly service the device. If vibration does not resolve after greasing the shaft, it must be replaced.
The gearbox on the trimmer is used to transmit rotation from the shaft to the cutting part. It includes a housing, bearings and gears. In its part, the following malfunctions can occur.
Baskingtransmission unit. The reason is the absence or unsatisfactory quality of the lubricant. It must be added or completely replaced. Also, this phenomenon may occur when new gears are installed. In this case, you need to let the tool work under light loads, regularly interrupting work to avoid overheating of the equipment.
Knock, play, shaft jam talk about deformation of bearings. Replacement required.
Transmission mechanism staggers or flies off the bar. This means the case is damaged. It is necessary to replace the rod or tighten it with a metal clamp, if the damage is minimal.
The gear does not hold on the boom. This is characteristic of a worn joint. You can change the bar or rewind the electrical tape.
The knife does not rotate or stops under load. So. the gears are worn out (fully or partially). Replacement parts required.
Typical Trimmer Failures
Electric trimmers have far fewer knots that can break. These are parts such as the power button and electric motor.. Also, mechanical malfunctions of electric braids are not uncommon.
The first part to be checked if the tool does not turn on is the start button. The problem may be in it or a broken cable inside the device. For diagnostics, disassembly of the handle and dialing of parts with a multimeter are necessary.
If the wire and start button are intact, you need to check the electric braid motor. To do this, the case is disassembled, the brushes and the collector are inspected. If they are OK, check the stator and rotor of the motor.
If the motor starts, but the cutting unit does not rotate, the cause of the malfunction may be a breakdown of the flexible shaft. This happens in the absence of regular maintenance of the equipment. The problem is relevant for an electric braid with an engine located on top. To eliminate it, you will need to disassemble the braid and lubricate the shaft.
Important! Lubrication of the flexible shaft should be carried out regularly, otherwise it undergoes strong friction and quickly deforms.
There is no flexible shaft on trimmers with a lower motor location, but they may break the main shaft onto which the fishing line reel is mounted. The reason is bearing failure. The solution is to install a new part.
In addition to the electric motor, the thermal relay is subject to verification. This part is "called" by a tester or multimeter. Also, a malfunction may be due to open wires or poor contacts.
Summarize. To repair the trimmer, you need to know its weaknesses and characteristic malfunctions, which depend on the design features and operating conditions. Possessing this information, it is possible to identify the problem node by typical symptoms and effectively eliminate the breakdown on its own if it does not concern the engine (both gasoline and electric) or the carburetor.
The trimmer is a necessary and useful tool for a summer cottage and a private house. Many own and actively use it, but not everyone knows how to replace a fishing line in a trimmer, especially at first.
In this manual, we will step by step analyze the entire replacement process. Looking ahead, there are two ways to line the trimmer spool with fishing line. There is no fundamental difference. the difference is that in the first case there will be one fishing line, folded in half, and in the second there will be two lines of such lines.
For clarity, the mowing head (spool) was removed from the lawn mowers. To replace the fishing line, you do not need to remove it, everything is done locally. It does not take much time.
We disassemble the trimmer spool. it rests on the latches-latches. Remove the cover by pressing on the latches. If you do not have enough effort with your hands, then use a screwdriver.
The spool consists of the following:
The principle of action is as follows. By pressing the button, the coil presses on the spring and exits the locking grooves in the spool cover. While holding the coil in this state, you can twist, thereby adjusting the length of the fishing line. When you release the button, the housing spring returns the coil to its original fixed state.
Disassembled Trimer Spool
Below on the coil there are several holes for different diameters of the lines. Different trimmer manufacturers may vary. In some cases (as here) they are signed, in others not.
These holes are needed to fix the fishing line when replacing it. After winding on a woman’s fishing line, the ends of the latter are inserted into them. This is necessary so that the scaffold does not unwind at the time of installation of the coil in the trimmer housing. In other words, it facilitates the replacement of fishing line.
Fishing Line Holes
There are models without specifying the diameter of the consumable. Then, in order to find out what the maximum diameter of the scaffold can be used, it is tried on through the holes for removing the fishing line from the body of the trimmer spool (see the figure below).
Fitting on fishing line outlets
The reel has two sections for fishing line, separated by a partition. They may not be. They are needed only to distinguish and facilitate winding of the consumable.
Two sections for fishing line
Initially determined with the required length of the loess. The latter is wound in one of the sections of the coil so that it does not go beyond its limits. In this case, 3 mm was wound, the length was about 2 meters. Those. for two sections you will need a 4 meter cut. this is for the 1st method. For the second method, you need two segments of 2 meters.
Determination of the required length of fishing line
Now you need to figure out which side you need to wind it. To do this, many manufacturers of trim tabs on the coils apply special designations such as in the figure below.
Special designation on the reel
If such designations were not found, then you need to pay attention to the body of the spool. There is without fail an arrow that indicates the movement of the mowing head. The line is wound in the opposite direction.
Designation on the spool housing
Bent in half fishing line
The prepared segment (in this case 4 meters) is bent approximately in half. one segment should be 15-20 cm longer and inserted into a special slot located on the dividing wall.
The fishing line is inserted into the slot
In a previously defined direction, the fishing line is wound. This is done in a tight fit, the line is neatly distributed. In this case, you need to wind a segment that is longer in the section that is closer to the button.
There are designs in which the division of the coil into two sections is not provided. This does not change anything, the fishing line is wound in a similar way. It is only necessary to ensure that the segments do not overlap among themselves.
The first segment that ends at the bottom of the coil, i.e. one that is closer to the fixing holes.
This tip is placed in the corresponding diameter hole. The fishing line is firmly fixed.
The fishing line is firmly fixed
A long section is wound another half turn. There it is similarly fixed. In this case, the segment crosses another section of the coil.
A long section is wound another half turn
The fixed ends of the wound fishing line are inserted into the holes of the trimmer spool housing.
The fixed ends of the wound fishing line are inserted into the holes of the trimmer spool housing
The coil is attached to the body. The ends of the fishing line are pulled with force so that the fishing line previously fixed in the holes of the reel springs out. This is easily determined by the characteristic sound (click).
The ends of the fishing line pull
The coil with the button is latched into the body of the trimmer spool.
The coil with the button snaps into the body of the trimmer spool
Replacing the fishing line was successful. In this case, you need to install it back on the trimmer and you can start mowing the grass.
It should be repeated, you do not need to remove the spool from the trimmer. this was done to make the process of replacing the fishing line easier. You can disassemble the spool in place, wrap it on a reel and put it back.
Successfully replacing fishing line
The tips so that they do not hit the trimmer cover can and should be cut.
Method 2. two segments
Two wound lengths of fishing line
Method number 2 fundamentally no different from method number 1. The only difference is the two wound lengths of fishing line, instead of one.
The end of each segment is bent
The end of each segment is bent.
Two special locking sockets
There are two special locking sockets on the coil (see figure above).
Start winding the fishing line
They hook onto it with a hook formed earlier on the fishing line, and begin to wind the fishing line.
Winding is carried out in a special order.
The winding should be carried out in the following order: first the bottom line, i.e. the one that is closer to the fixing holes at the bottom of the coil, and only then the upper one, i.e. the one that will overlap the bottom section.
The bottom line is wound
The tips are made into the holes in the body of the trimmer spool. They are pulled up to a click, which indicates that the line has come out of the clips.
The tips are threaded into the holes of the trimmer spool housing
The coil is fastened into the housing. The fishing line in the spool is replaced.
The fishing line in the spool is replaced

Replacing the fishing line in the trimmer: 2 easy ways
Feedback from our readers is very important to us. Leave your rating in the comments with the argument of your choice. Your opinion will be useful to other users.
Guaranteed production of a factory trimmer refill will inevitably require replacing the fishing line. Having a very rough idea of how to fill the fishing line into the reel of the trimmer yourself, beginners are reluctant to take up this matter. However, with some skills, mastering this simple science does not present any difficulties, and the similar instruction presented below will facilitate this process as much as possible.
Video: How to Change a Fishing Line In a Stihl Electric Trimmer
First of all, for winding fishing line it is required to remove the reel (bobbin, spool) from the trimmer. specific actions will depend on the complexity of the configuration and the type of product itself:
Small electric trimmers with a working arrangement of the engine and the coil in the lower part, as a rule, have side keys on both sides of the bobbin. By pressing them simultaneously, the upper part of the reel, together with the internal contents for winding the fishing line, is disconnected, while the lower one remains on the trimmer. It is advisable to disassemble the bobbin on an even smooth place so that the spring included in the design does not pop out and is not lost;
electric and gasoline trimmers with a curved bar without the possibility of installing a knife, as a rule, have coils with a special wing: in such designs, you should hold the spool in one position with one hand and rotate the locking reel on the wing nut with the other counterclockwise. After disconnecting the nut, the entire reel is removed.
electric and petrol trimmers with the possibility of installing the knife on a straight bar (for example, Stihl trimmers) have a hole under the bobbin. For the motion of the rod to be stationary, a screwdriver or other suitable object is inserted into this hole and with a slow rotation, such a mutual arrangement is achieved when the screwdriver enters the hole and the bobbin is fixed. After that, the coil body scrolls clockwise (with the left thread) and is removed from the trimmer.
For the second and third cases, the coils, depending on the design, are disassembled in various ways. In bobbins with a lamb, a lamb is twisted, in coils with latches, latches-clamps are pressed and one part of the coil is released from the other. If the halves of the spool are threaded, it is enough to turn them by hand in opposite directions until completely unscrewed.
We carry out winding fishing line
Slowly completed disassembling the spool of the spool without losing its spare parts allows you to go to the main task. winding the fishing line into the reel. Technological features of the design of the spool and the number of working antennae determine the sequence of actions.
Coil with one working antenna
The simplest option and a simple sequence of actions:
The dimensions of the bobbin and the length of the original factory winding determine the recommended fishing line length for winding. 2. 5 m.
One end of the fishing line is inserted into the fixing technological hole located inside the spool.
The fishing line is wound on the drum in the reverse direction of rotation of the spool in the trimmer product direction. as a rule, on the inner side of the bobbin an arrow indicates which side the winding is carried out.
A small area of fishing line is left free to bring it out. it is fixed in a specialized groove on the inside of the reel, designed to hold the winding when assembling the spool in working condition.
The left end of the line is passed through the hole on the outside of the bobbin.
The bobbin halves are assembled and put on the trimmer bar.
Coil with two working antennae
In this type of spools, you should determine the number of grooves for winding fishing line lying on the inside of the reel:
one groove. both antennae are wound together along one groove;
two grooves. each antennae is wound on an individual groove.
In both cases, a 2-3-meter-long fishing line is taken. In single-groove reels, the fishing line is pulled into the through hole, its ends (antennae) are folded together and aligned, after which they are wound in the opposite direction of rotation of the bobbin on the side of the bar. the correct direction of winding is usually indicated inside the arrow. In the presence of fixing grooves, the ends of the fishing line are threaded into them or held by the fingers of their free hands, threaded into the through hole of the outer half of the bobbin, the spool is closed and attached to the bar of the trimmer.
The difference between winding fishing line in two-groove reels is that initially a piece of fishing line 2-5 m long is folded in half (to determine the middle bend), and the bend loop is inserted into a special groove between the grooves. Both antennae of the fishing line are wound each in its own groove, the fixation of the antennae and the reel assembly is similar to the one-groove variant discussed above.
The first implementation of this procedure may seem long and rather laborious, but with time and experience this task will be solved much faster and easier.
The video below will clearly show how to put the fishing line into the coil of the trimmer and wrap it correctly. this operation is not complicated and with some patience will surely succeed:
Automatic reeling of fishing line
There is a variety of coils in which the automatic mechanism coils on its own. from the user it is enough just to properly fill the line. The fishing line is passed through the hole on the inside of the case, its antennae without winding is passed through the hole on the external case, the bobbin is assembled, and when the winding button is rotated, the line inside is wound up independently. In such a spool, it is impossible to make the winding incorrectly: the mechanism itself will determine the correct direction, since it can only turn in one direction.
The trimmer is a convenient and easy-to-use tool for mowing grass and pruning small bushes and trees. As a cutting element, it often uses fishing line (string, cord), because it costs less than blade knives and is safer to use. With intensive use of the tool over time, you will need to change the line on the trimmer. This process is similar on mowers from different manufacturers, be it Husqvarna or Huter, with possible minor differences.
What is needed to replace the cord
When the trimmer is used regularly for grass mowing, the discs become dull, but they can be sharpened and continued to be used. The fishing line in the reel tends to end, so there is a need to refuel a new one, for which you need to determine the type of head and prepare a cord of the required thickness and length.
So, the mowing head is a cylindrical body in which a bobbin with fishing line is placed. Such a detail is present both on trimmers and on gasoline braids of any brands, be it Bosch, Makita, Stihl or another brand. The heads are of three types, depending on the method of refueling and feeding the fishing line.
The principle of operation of the heads auto group consists in the fact that they independently feed the fishing line when the mower reduces the engine speed. Such designs are convenient when working on large areas, but have the disadvantage of high cord consumption.
Heads semi-automatic group easy to operate. automatic line feeding is performed at maximum engine speeds. To release the cord lock, gently tap the tool on the ground, after which the unlocked thread extends from the spool. Cutting to the required length is carried out with a knife mounted on a protective casing.
Trimmers with manual feed the cord must first be turned off, and then pull out the fishing line yourself.
On a note! The most convenient and best priced are semi-automatic cord reels.
Coils for electric and gasoline braids can be with one or two antennae fishing line. The former are used to trim low grass overgrowth, and the latter are used to trim tall grass and small bushes.
Preparation for replacing fishing line
Before replacing the fishing line, you need to pull out and then disassemble the head. Usually it includes a casing, a spring (on some models), a bobbin with fishing line, a cover. It is necessary to disconnect the electric trimmer from the network (or muffle the gasoline), and then proceed to remove the coil. It can be fixed in two different ways: in the first case, it is necessary to completely disassemble the head, and in the second. just remove it from the gearbox shaft on which it is mounted.
find the latches on both sides, press and remove the cover to open the internal device of the head;
there is a bobbin under the cover, it must be carefully removed from the case (sometimes a spring hides under it, it should also be carefully removed to the side so as not to lose);
after removing the spool, a fixing bolt (or screw) becomes visible in the center of the housing, which must be unscrewed in the opposite direction to the clockwise movement;
after removing the fasteners, hold the housing by swinging movements to remove the coil from the gearbox shaft.
Second way involves the following actions. The coil head is mounted on the gearbox shaft. To disconnect it, it is necessary to lock this shaft. Usually in braids, for example, of the Champion or Stihl brand, a hole is made for this, into which a nail, a rod or a screwdriver is inserted. After fixing the shaft in a fixed position, holding the housing, it is necessary to start turning the head clockwise, since the thread on the shaft is usually applied left.
Now that the head is removed and disassembled, it is necessary to determine how thick the cord should be. You can find out the suitable diameter for your trimmer by looking in the user manual or on the bobbin itself, usually similar information is indicated on it. Another way is to insert the thread into the hole from which it is fed. If the scrum goes without difficulty, it can be used for work.
On a note! To understand how much fishing line to reel for the reel, you need to wind it on a bobbin so that the height of the reel is not greater than the diameter of the sides. If the cord protrudes beyond the edges, the coil cannot be hidden in the casing.
Line winding algorithm
The order of winding the fishing line depends on the type of reel. with one or two antennae, as well as with automatic charging of the cord.
To the coil with one antennae
It is very easy to wind a fishing line onto a reel with one antennae. In such designs, depending on the brand of trimmer, two to five meters of cord is placed. The edge of the fishing line in the spool must be tucked into a special hole or groove, after which the string is wound in the direction opposite to the rotation of the coil during operation.
Advice! To understand which way to wind the thread, you should look at the bobbin case. usually marks are made on it that indicate the direction of movement of the bobbin during operation.
After the fishing line is wound, you need to leave a small piece (15-30 cm), thread it into the exit hole of the spool and reassemble the head.
To the coil with two antennae
In spools of this type, you need to inspect the inside of the coil and determine the number of grooves for winding the cord provided in it.
Important! If there is one chute in the coil, then both antennae must be wound along a common groove, if two, then on separate tracks.
For winding, you need to take a piece of fishing line with a length of two to three meters. For single groove spools it is necessary to fill the line into the through hole, align the mustache, align and wind it on the reel in the direction opposite to its rotation during operation. If locking grooves are provided, they need to thread the ends of the cord, then pull them into the outlet, then close the coil and put it back on its place.
For two-groove spools the difference is that the length of the string should be folded in half. Next, you need to charge the middle of the bend into the groove between the grooves, then wrap each of the pieces of fishing line along its path, fix the antennae and assemble the reel as well as the bobbin with one track.
On trimmer head with automatic refueling
For heads with automatic refueling, just enough start and pinch the edges of the line, and the tool will carry out further winding on its own when turned on. It is impossible to make a mistake here, because the coil itself recognizes how the antennae should be located.
On a note! The advantages of trimmers with such a head include the convenience of laying the cord, and the disadvantages are the high cost and complicated repair.
Fishing line. varieties and the possibility of replacing with other material
The cord for the trimmer can be of different diameters (from 1.2 to 4 mm), and you need to choose it depending on what kind of vegetation you want to mow. the thicker the fishing line, the more rough grass it can handle. Experienced users recommend putting a fishing line with a thickness of 2 mm, which is universal.
Fishing line shape can be round (for juicy grass) or with sharp edges in the form of a square or asterisk (for mowing dry grass). The second type is less durable and wears out faster than a round cord.
One of the popular questions regarding the operation of trimmers is whether it is possible to replace the special cord for mowers with other materials, for example, metal or steel cables and strings, wire, etc. You need to know that the installation of such items not recommended, because with them the trimmer turns into a dangerous technique. During the mowing, pieces of wire or metal will constantly break off and fly apart in different directions, risking injury to the worker. And if you accidentally touch their limbs during work, a serious injury is guaranteed.
For trimmers who are interested in using fishing line, we answer. this is allowed, but it will tear and wear much faster, which means that it will require frequent replacement.
Advice! Fishing line is well suited for harvesting grass near a fence or wire mesh. instead of spending an expensive trimmer cord, you can charge large-caliber gear (2-3 mm), which is much cheaper.
Replacing fishing line on the disc
Depending on the type of vegetation covering the garden (lawn) and requiring removal, the fishing line changes to disk. This is necessary, since the cord is used only for grass of small height, and if you need to mow tall growth, shoots of trees or shrubs, instead of a string it is better to use metal or plastic knife-disks. Installing them correctly is very simple, the detailed process is usually described in the user manual and is similar for trimmers of different brands, be it Al-Co, Oleo-Mac, Patriot or another brand of equipment. To change fishing line to knives, you must:
lock the shaft and remove the coil by turning it clockwise;
put the knife on the sleeve;
install the locking cover and in a counterclockwise direction tighten the nut, and then tighten it with a wrench.
You can read in detail how to change the reel with fishing line to disk in the device’s instruction manual.
Solving possible fishing line problems
Most of the problems associated with fishing line, similar for different trimmers and are solved in a similar way.
Regular line breaks are caused by:
the presence in the mowing grass of solid objects: branches, stones, etc., contact with which breaks the string;
mowing the grass is close to the fence, and if it is mesh, the fishing line breaks even faster;
low-quality cord. a replacement for a new reliable consumable is necessary;
wear of the outlet openings in the mowing head, as a result of which the fishing line breaks off from friction against the sharp edges of the bushings. replacement of the part with a new one is required.
High consumption of fishing line
Typically, the fishing line ends very quickly if you constantly tap the semi-automatic reel on the ground or press it firmly to the surface. In this case, the head unlocks, the cord lengthens, and the knife cuts it. The second option is the fast consumption of fishing line. a trimmer with an automatic reel is not used correctly. If the mower regularly reduces the engine speed, the string is constantly lengthened and cut, and as a result is quickly consumed.
The string does not hold
If the coil is semi-automatic type the spring is weakening, the fishing line does not hold and unwinds during operation. The cord extends, is cut with a knife, as a result, the owner of the equipment notices that the thread ends quickly.
Advice! To test the tool, you need to remove the protective cover and start the engine. if the fishing line extends, this means that the spring must be replaced with a new one.
Fishing line crashes
If the string flies when mowing, this is another evidence that the spring in the bobbin is weakened or completely lost when the head was not carefully dismantled. As a result, the cord does not hold and jumps out during rotation.
The string does not extend
In automatic reels and semiautomatic machines, the cord is fed without stopping the trimmer. If this does not happen, then:
the fishing line in the head is not wound correctly, so the reel does not spin;
the winding of the fishing line is uneven, so the cord gets stuck between the turns and does not come out. to prevent this from happening, you need to wind the thread carefully, avoiding distortions, turn to the turn;
the ends of the cord coming out of the holes are very short, there is not enough centrifugal force to remove them, so the fishing line is not fed. before turning on the trimmer it is important to adjust the length of the thread and lengthen it a little if necessary;
the cord stuck together.
The coil does not spin
The reasons why the reel does not spin are similar to the lack of line feed. This is an incorrect or uneven winding of the string, its sticking, as well as the short ends of the cord coming out of the holes.
Fishing line sticks together
If the fishing line sticks together during operation, the main reason is the installation of a low-quality cord. During operation, the coil heats up, and a poor-quality string melts and sticks together. The second reason is the collision of the cord with solid objects. In this case, its sharp braking occurs, the thread is pulled into the head and sticks.
Advice! To avoid problems, you can apply mineral oil to the surface of the fishing line or, after winding on the head, spray it with silicone. A more competent solution will be the acquisition of a good quality head, which will forget about such problems.
So, replacing the fishing line on the trimmer is not difficult if you know how to disassemble the coil and wind the cord. This process is similar for technology of different brands. A detailed description can be found in the instruction manual of the tool or watch the video.
Fuel mixture for a chainsaw It is prepared from two components. oil and gasoline. Chainsaws are equipped with two-stroke engines, so the oil is not added to the lubrication system (like a four-stroke engine), but directly to gasoline. In this case, it is very important to observe the correct proportions of the ingredients, of course, in no case try to work on clean gasoline, because in this way you will very quickly “kill” the chainsaw.
If we talk about which gasoline to pour into a chainsaw, it will optimally use fuel with an octane rating A-95, in this case, fuel economy can turn out disastrously. Often, European manufacturers indicate that you can use A-90 or A-92 gasoline, but in post-Soviet countries the quality of gasoline is inferior to European, so in our realities it is better to use better gasoline.
As for the most proportions of a benzo-oiled mixture, then everything is simple: you must follow the instructions for the tool. All manufacturers of chainsaws indicate the required ratio in the instruction manual or in the instrument passport, in addition, the proportions for refueling the chainsaw may differ depending on the model of the chainsaw. As a rule, the proportion of oil and gasoline to the chainsaw of famous manufacturers is a ratio of 1:40 or 1:50, which means 1 part of oil for, for example, 40 parts of gasoline. Now arithmetic 1 liter of gasoline = 1000 ml of gasoline, divide by 40 and get 25 ml of oil. If you perform the same steps to the ratio 1:50, then we get 20 ml of oil per 1 liter of gasoline. As for budget-made chainsaws made in China, the situation is slightly different. The ratio of gasoline and oil for chainsaws made in China1:25, that is, 1000 ml of gasoline divided by 25, we get 40 ml of oil. The thing is that in branded chainsaws a good assembly and the distance between the pistons and cylinders in the engine is much smaller than that of Chinese chainsaws, therefore the required amount of oil differs almost twice.

In order to measure the correct portion of oil, use an ordinary medical syringe of sufficient volume.
Another subtlety. in a dry canister for gasoline, first fill in gasoline, and then oil. The procedure, on the contrary, is fraught with a poor quality fuel mixture, because the oil is more dense, sticks to the bottom of the canister. what a good mix.
Be sure to prepare the fuel mixture in a can and pour ready-made special fuel into the gas tank! Never cook or mix directly in the fuel tank of a chainsaw!
If the question of how to breed gasoline for a chainsaw figured out, then on storage conditions and shelf life of the fuel mixture It is worth saying a few words. It’s best and easiest to cook a 1-liter gasoline-oil mixture, it is recommended to do this immediately before working with the tool. The fuel tanks of chainsaws have a volume of 0.3 to 1 liter. In domestic use, in one session, the entire volume of the prepared combustible mixture is rarely used, so the remainder can be saved until the next session. It is necessary to store the fuel mixture in a special canister for gasoline, in a dry, dark place. It is optimal to calculate that shelf life of the finished mixture will be 7-10 days. The fact is that the oil currently on the market is not synthetic, but organic, that is, natural. After 10 days, all lubricating properties are lost, gasoline simply “eats” the oil. Naturally, it is no longer possible to use such fuel, this can cause breakdown and failure of the chainsaw.
At the end of the work, it is necessary to drain the fuel mixture, start the chainsaw, the tool will stall (so that the saw has a dry carburetor) and now you can leave it until the next operation session.

The true invention relates to a trimmer and a protective cover for it.
DESCRIPTION OF THE PRIOR ART
A trimmer that cuts grass and shrubs is well known. The trimmer is provided with a cutting blade that rotates, and a protective cover that partially covers the cutting blade. In this type of trimmer, when the cutting blade is replaced with a blade of a different size and / or type, the size of the protective cover does not match the cutting blade, and the cutting blade may touch the protective cover, or the cutting blade may protrude more than necessary from the protective cover.
With regard to the difficulty described a little higher, Japanese Patent Application Laid-open No. 2001-333616 and US Pat. No. 4,864,728 disclose a trimmer that is made in such a way that a portion of the protective cover is removably attached. In this trimmer, the protective casing is provided by the main body and the sliding part, and the size of the protective casing can be adjusted by attaching and detaching the sliding part. In other words, it may be possible to make the protective cover larger by attaching the expandable portion, and it may be to make the protective cover smaller by detaching the expandable portion. Alternatively, it may also be possible to change the size of the protective cover by replacing the attached sliding part.
A conventional protective cover has a structure in which the sliding part can be simply attached and detached without the use of a tool. If a design of this type is chosen, then when the protective casing is in contact with the outer element, for example, the sliding part can unintentionally detach, and the user’s work can be blocked. over, in certain countries and / or regions, a design that allows the detachable part to be detached without using a tool may be prohibited by law.
In connection with these circumstances, a design that secures the sliding part with screws or bolts may be proposed. By the choice of this design, it can be firmly fixed to the sliding part, in such a way that inadvertent detachment of the sliding part is prevented. But the screws or bolts can weaken from shock and vibration, and, as follows, there is a brand new problem that the screws or bolts can fall out. over, in a design using screws or bolts, attaching the sliding part asks for a tool and also takes time, causing excessive inconvenience for the user.
In view of the troubles of the prior art outlined above, the true description opens a protective cover for the trimmer, in which the sliding part can be simply attached, and the attached sliding part is prevented from falling out.
Technical obstacle solution
The trimmer contains a cutting blade and a protective casing, made with the possibility of partial closing of the cutting blade. The protective casing comprises a main body and a sliding part, made with the possibility of removable fastening to the main body, and the sliding part is made not requiring any tool for its attachment to the main body, but requiring very little 1 tool to detach it from the main body. According to this trimmer, the user can simply attach the sliding part without using a tool. As attached, the sliding part is firmly fixed to the main body and cannot be detached without the use of a tool. Power trimmer electro with a different bobbin design how to remove the protective cover. As follows, inadvertent detachment of the sliding part from the main body is prevented.
One of the parts including the main body and the expandable part of the protective casing may desirably be provided with a snap portion, the other of the parts including the main body and the expandable part of the protective casing may desirably be equipped with an engaging hole, and the engaging hole may desirably be adapted engaging the snap-in portion from the inside and opening the engaged snap-in portion from the outside. The engaging hole may desirably have a size that allows the passage of the tool, but prevents the passage of the finger. For this trimmer, when the sliding part is attached to the main body, the snap-in portion can cling to the engaging hole, while at the same time passively deforming. How to start with a gas trimmer and if you remove the protective cover c. How to remove the head from the trimmer and change how to remove and disassemble in the huter and champion devices. A tool is not required for this. When detaching the sliding part from the main body, the snap-in portion engaged with the engaging hole will need to be pressed with inventory in order to disengage. In other words, the sliding part cannot be detached without the use of a tool. According to this design, a separate connecting element, such as a pin, is not required, and troubles such as falling out of this type of connecting element can be avoided.
Preferably, if the sliding part is adapted to be attached to the main body by sliding in one radial direction relative to the main body and detached from the main body by sliding in the other radial direction relative to the main body, the snap-in portion can be placed on the end portion in one radial direction of the main body or end portion in another radial direction of the expandable part. According to this design, the section where the snap-in portion is in contact with the main body or the expandable part when the expandable part slides relative to the main body may be shortened. In other words, the section in which the resistance appears due to the contact of the latch portion can be shortened.
Preferably, one of the parts, including the main body and the expandable part of the protective casing, may be provided with a contact portion configured to contact the snap portion from the inside when the snap portion is pushed out of the engaging hole by inventory. According to this design, even if the user presses the latched portion very hard with the inventory, the latched portion is not extremely deformed, and breaking of the latched portion can be prevented.
Desirably, the trimmer related to the true invention may comprise a workstand including a tip on which the cutting blade is placed, and a safety rod extending from the workstand and arranged to be in front of the user when the user is holding the trimmer. In this case, the snap-in portion engaged with the engaging hole and the safety rod rich on the work stand may desirably be placed on one side relative to a plane containing the axis of rotation of the cutting blade and the central axis of the work stand. Usually, the user does the detachment of the sliding part, putting the trimmer on the ground. In this case, when the latch portion engaged with the engagement hole is oriented upward, then the latch portion may simply be pressed by inventory. But, if the protective rod, which is rich on the working stand, is placed on the back side of the snap section, which is engaged with the engaging hole, then this means that the trimmer rests on the protective rod, and the position of the trimmer is unstable. As it follows, the snap-in area, which may desirably be engaged with the engaging hole, and the safety rod, which is rich on the work stand, are placed on one side, as a result of which the user can simply perform the task of detaching the sliding part in the lying position of the trimmer.

FIG. 7 shows an enlarged view of a region VII of FIG. 3, and FIG. 8 shows an enlarged view of a region VIII of FIG. 5. Fig. 9 shows a sectional view along the mowing line IX-IX of Fig. 7, and Fig. 10 shows a sectional view along the mowing line X-X of Fig. 7. As shown in FIG. 7, FIG. 8, FIG. 9, and FIG. 10, a snap portion 54 is formed on the expandable portion 50 of the protective cover 30, and an engaging hole 44 that accepts the engagement of the snap portion 54 is formed in the main body 40 of the protective cover 30. In the protective casing 30, the latched portion 54 of the expandable portion 50 engages with the engaging hole 44 of the main body 40 when the expandable portion 50 is attached to the main body 40, thereby motionlessly securing the expandable portion 50 with respect to the main body ca 40 (see Fig. 7, Fig. 9 and Fig. 10). When the latch portion 54 is disengaged from the engaging hole 44, the expandable portion 50 becomes movable relative to the main body 40, and the expandable portion 50 can be detached from the main body 40 (see FIG. 8).
An engaging hole 44 is formed on the guide portion 42 of the main body 40. On the other hand, a snap-in portion 54 of the expandable portion 50 is located on the inside of the guide portion 42, and engages with the engaging hole 44 on the inside. As shown in FIG. 9, the inclined surface 58 is formed on the snap-in portion 54. over, the inclined surface 48 is also formed on the main body 40. When the sliding part 50 is attached to the main body 40, the sliding part 50 slides in one circular direction relative to the main body 40 (to the right in FIG. 9). In this case, due to the mutual contact between the inclined surfaces 48 and 58, the latched portion 54 passively undergoes elastic deformation and moves to the inner surface of the guide portion 42. When the sliding portion 50 slides further, the latched portion 54 slides along the inner surface of the guide portion 42 and engages with an engaging hole 44. As a rule, the unit and remove the protective cover. The knife should be removed from the trimmer. The mutually opposite front surfaces of the snap portion 54 and the engaging hole 44 are perpendicular to the sliding direction of the expandable portion 50. Therefore, the sliding movement of the expandable portion 50 is prevented, and the extendible portion 50 is fixed relative to the main body 40. Therefore, with the protective casing 30 according to the present embodiment, it is easy to attach the sliding part 50 to the main body 40, without using a tool.
As described above, when the expandable portion 50 is attached to the main body 40, the snap portion 54 slides along the inner surface of the guide portion 42 in an elastically deformed state. In this case, the user experiences a drag force caused by friction. Regarding this issue, in the present embodiment, the attachment direction of the expandable portion 50 is one circular direction (direction D1 shown in FIG. 4), while the latch portion 54 is provided at the end portion in another circular direction (direction D2 shown in FIG. 4) the sliding part 50. Remove the coil and the protective cover with how to remove the coil from the trimmer — nowhere. By selecting this type of construction, it is possible to reduce the distance that the snap section 54 slides along the inner surface of the guide section 42 in an elastically deformed state when the expandable portion 50 is attached to the main body 40. As a result, the distance at which the aforementioned resistance force is tested when the user attaches the expandable portion 50 is reduced, and the damage (deformation or friction) received by the snap-in portion 54 is also attenuated.
The engaging hole 44 is a through hole, and the latch portion 54 is exposed from the outside when engaged therein. Accordingly, it is possible to disengage the latch portion 54 from the engagement hole 44 using a tool such as a screwdriver to press the latch portion 54 externally. Here, the engaging hole 44 is relatively small in size, which allows the passage of a tool, such as a screwdriver, and prevents the passage of the user’s finger. In other words, a design is selected in which the latch portion 54 that is engaged with the engagement hole 44 cannot be pressed and cannot be disengaged from the engagement hole 44 with a fingernail or a user’s finger. Therefore, with the protective cover 30 according to the present embodiment, unless the tool is used, it is not possible to disengage the snap portion 54, and the expanding portion 50 cannot be detached from main body 40.
The recessed portion 56 that the front tip of the tool receives is formed in the snap portion 54. As shown clearly in FIG. 9, the recessed portion 56 is V-shaped in the depth direction and contains a pair of beveled edges 56a, 56b. Here, the pair of beveled edges 56a, 56b are mutually asymmetrical, and the inclined surface 56a, which is located in the direction of detachment of the sliding part 50, is formed larger. By this design, by pressing the latch portion 54 with the tool, the user can easily rest the front tip of the tool at the larger beveled edge 56a and can easily apply force in the other circular direction (direction D2 shown in FIG. 4), which is the direction in which the sliding part 50 is detached.
As shown in FIGS. 9 and 10, a wall portion 46 located inside the engaging hole 44 is formed on the main body 40. The wall portion 46 is opposed to the latched portion 54, which is engaged with the engaging hole 44, through the gap, from the inside. When the latched portion 54 is pressed by the tool and disengaged from the engaging hole 44, the latched portion 54 is in contact with the wall portion 46. over, deformation of the snap portion 54 is prevented by this contact with the wall portion 46. Therefore, even if the latch portion 54 is pressed too hard by the tool, excessive deformation of the latch portion 54 is prevented. The wall portion 46 limits the deformation of the snap portion 54 and thus prevents the snap portion 54 from bending and breaking.
In the present embodiment, the latch portion 54 that is engaged with the engagement hole 44 and the safety rod 64 are located on one side of the user when he is holding the trimmer 10. specifically, the latch portion 54 that is engaged with the engagement hole 44 and the safety rod 64 are located on one side with respect to a plane containing the axis of rotation of the cutting blade 22 and the central axis of the work stand 60. Typically, the user detaches the expandable portion 50 when the trimmer 10 lies on the ground. In this case, if the trimmer 10 is located snap-in portion 54, which is engaged with the engaging hole 44, up, then the snap-in portion 54 can be easily pressed with a tool. If the protective rod 64 is provided on the working stand 60, then depending on the position in which the trimmer 10 is placed, the trimmer 10 rests on the protective rod 64, and the position of the trimmer 10 is unstable. Therefore, in the present embodiment, the latched portion 54, which is engaged with the engaging hole 44, and the safety rod 64, which is provided on the work stand 60, are located on one side. Therefore, even if the trimmer 10 is positioned with the snap-in portion 54 up, the safety rod 64 does not interfere, and the position of the trimmer 10 is also stable. How to remove the coil from the trimmer, press the coil lock and turn the protective one. Therefore, the user can easily perform the task of detaching the sliding part 50.
A specific embodiment of the present idea is described above, but it only illustrates some of the possibilities of the idea and does not limit the points of its claims. The prior art set forth in the claims includes changes and modifications of the specific examples set forth above.
For example, in contrast to the design of the present embodiment, it is also possible to make the snap portion 54 on the main body 40 and to make the engaging hole 44 in the expandable portion 50. over, it is also possible to make the snap portion 54 respectively in the main body 40 and sliding part 50, and make the engaging hole 44 in accordance with the corresponding snap-in portion 54, respectively, in the expandable portion 50 and the main body 40. In addition, fixing the main body 40 and the extendable portion 50 can also use a different locking structure, rather than the snap-in portion 54 and the engaging hole 44. For example, the main body 40 and the sliding part 50 may be fixed by a connecting element, such as a pin or clip. In this case, preferably, the connecting element is designed so that it can be attached without using a tool, but required a tool to detach it.
