Electric trimmer for grass does not look aside.

Do.it.yourself electrimmer repair: detailed instructions for a novice master with pictures, schemes and photos

For some reason, often the need to carry out the repair of an electrimmer with your own hands arises at the most inopportune moment when it is necessary to urgently mow grass, and the breakdown does not allow this to do this.

Most of the defects that occur is not difficult and can be eliminated literally on the spot with a simple improvised tool. But for this you need to have basic knowledge of the design of your mowing.

I share my own experience acquired for five seasons of exploitation of my ECO GT-800L, as well as help friends and neighbors in this matter in this matter. I myself try to pay attention to preventive maintenance, timely conduct technical inspections and verification.

What you need to know about the device of the electrimmer before the start of its repair: 2 types of structures

Trammers for herbs for mowing herbs with power supply from electricity are made with a capacity of 300 watts to 2 kW with two modifications. They are distinguished by the location of the engine:

Such products are created for different tasks, differ in weight, power, working characteristics. The first types of models are light and used to process the complex relief of garden paths under the bushes, near the flower beds.

Products with the upper engine arrangement allow you to process large areas, they are noted with high performance.

Both types of mowers can work from a household network 220 volts. However, elite products are created with food from the built.in portable battery. Most often they are used on light models, as shown in the photo above.

An example of a product with an upper engine and its layout show it in the photo of my Eco GT-800L below. The fastening of the belt allows you to hang a mower on the shoulder, and the handle provides convenient control of the cutting head during kosbe.

The working body is a spitter head with a fishing line. It can be supplemented with a cutting knife made of metal or plastic on powerful models. The torque of high revolutions for it is created by an electric motor, and it is transmitted by a kinematic scheme located inside an integral bar.

In more detail, the insides device show a photograph of the engine with the upper lid of the case on its trimmer. It is not equipped with a gearbox. This, by the way, is such a simple execution completely suits me.

The engine is turned on by a small final switch with a convenient plastic lid placed in the lower handle.

Features of the device of the electrical circuit: Briefly

The basic part is a typical collector engine in which the rotor of the stator windings gives the rotor to the bearing of the bearing.

The electric current that performs the main work flows through the closed circuit of all windings through the brush-collection mechanism.

The vast majority of engines as a protection against overheating of the insulation of windings use thermorelene. During the repair, we consider it as ordinary power contact in a closed state.

With a critical heating of the varnish of wires, it will simply open and interrupt the action of electric current.

All elements of the electric circuit are connected by wires and terminals to each other into the sequential site. A short cable with a fork is displayed out to connect to an extension cord.

How the torque from the engine is transmitted to the mowing head: 3 components of the kinematic scheme

It is used to lower the revolutions and, accordingly, increase the power on the output shaft.

On some designs, it is located immediately after the engine, built into its design.

In other models, it can be located from below the national bar: immediately under a mowing head and a protective cover.

Any of these gearboxes consists of two gears conveying rotation. In the upper photo, they have a cylindrical shape with a slanting tooth, and on the lower. conical, because they change rotation at an oblique angle.

The transmission of the torque from the engine is performed by a docking knot consisting of a cylindrical sleeve with a rectangular hole. The tip of the spring shaft of the corresponding form located inside the aluminum tube is inserted into it.

The rod of a trimmer for grass consists of two halves connected in series. Each part is made up of three details inserted into each other:

The joint of the bar is made in the middle of its length using an adapter with a screw connection, allowing to add the entire structure for convenient transportation on transport.

Below is a spiked head with a protective casing. To trim the excess fishing line, a knife is stationarily installed on it, reducing its length to the optimal value.

The main malfunctions of the starter of the trimmer for grass

It is not difficult to determine the cause of the breakdown of the starting device. There are several main options:

These details are shown in the photo below.

It may happen that the starting mechanism will be accidentally broken. The consequences will turn out to be deplorable if the ragged rope is wound around the flywheel of a working internal combustion engine: then the spring bursts, the pulley will tear off. But such cases when a complete replacement of the starting node is required, they rarely occur. In most cases, to fix the mechanism, it is enough to put a new spring or replace the cord.

Removing and disassembling the starter, replacing broken parts

To repair the starter of the trimmer for the grass, you will need to disassemble it first, and then collect it. This process is not a particularly difficult occupation. For work, you will need a screwdriver with the tip of the desired shape.

Everything should be done carefully, observing safety precautions, mainly that the spring does not injure the master if an accident.

Parsing the starting node

They disassemble the launch mechanism in order to install new parts instead of broken in the following sequence:

• spin a screw with a screwdriver, fixing the pulley with a starter lid;
• take out a spring and antennae;
• Remove carefully with the pulley (you need to unscrew the head or work, having dressed the glasses and gloves before);
• determine why the launch mechanism has broken;
• If the spring collapses almost completely, then it is replaced;
• When the spring exits from the hook, it is installed in the original place, bending the antennae before this (the photographs show the laying process);

To change the spring, you should work carefully and accurately: it can, under the influence of the effort caused by the installation of it in place, accidentally burst. Even if you carefully remove the video, then the spring strip flies very quickly from the coil and can injure your hand with its sharp edges.

Immediately putting a springy plate in the same place does not always work. It often slips, so attempts are required to repeat until the desired result is achieved.

Starter assembly

The assembly of the starting node is carried out in a number of stages:

When making the stated manipulations, it is necessary to lay two goals. If this is not done, then the spring over time damage the plastic cup, and when it is pulled. Because of this, a feeling appears, as if the spring had flown. To eliminate such a drawback, you need to install this part of a larger length or an additional goal.

When such spare parts are absent, you can just unscrew the screw a little, and the starter knot will begin to work without shaken. But this option is temporary. it is better to repair qualitatively as quickly as possible.

Spring tension

After installing the spring, it should be pulled. The following actions are performed for this:

• Remove the handle from the starter cord;
• Then the rope is inserted into the coil groove;
• They stretch the spring, rotating the coil in the direction opposite to the clock of the clock arrow (reviews);
• make the desired number of revolutions specified in the instructions for the use of the trimmer model used and the corresponding length of the cord used;
• At the very end, the rope is threaded into a hole designed for this, located in the starter cover;
• put the handle in place, fixing it with a node.

If after the repair the spring continues to fly, then you can get rid of this in the following ways:

• Squeeze the suitable piece of the plate into the groove at the location of the spring hook;
• drill holes on two sides of the groove in the coil, into which the spring hook is inserted and fix it using a wire.

Replacing a torn cord

A torn rope is replaced in the following sequence:

• The old cord is removed;
• choose a suitable rope (thickness and length);
• Having reached it through a special hole in the coil, a knot is tied;
• Sprinkle a spring, producing the required number of revolutions;
• Fix the pen.

It is better to stretch the spring plate along with the partner so that the edge of the cord does not hit the starter mechanism.

It is easy to assemble a starter on a trimmer and wound a spring, only you should do it carefully and with caution. For different models, the gas tanks of the launching mechanisms are the same, so they are repaired in a similar way. In this case, there are some nuances associated with their constructive features.

How to put on and hold it correctly?

The quality of your work also depends on what technique you use. For the right technique, you need to be able to hold the unit, and for convenience to wear it correctly. The fact is that not all trimmers for grass are equipped with a shoulder belt. If he is, then it needs to be worn so that you are comfortable. There are models of devices whose belt can be inconvenient, so try to put on a trimmer for grass as convenient as possible how it will succeed.

During long work, it also happens that pain in the back and muscles arise, so the most convenient tool can reduce the number of such troubles as conveniently as possible.

Another function is to adjust this belt. On better models, its convenience assigned a special role and made special positions that will allow the manager of a scythe not to experience inconvenience. You can adjust the belt in height, choosing the necessary for yourself.

Now let’s talk about how to hold the unit correctly. Various types of trimmers have different handles. For someone it is made in the form of a bicycle steering wheel (which ensures the distribution of the load on both hands). On some units you can see the handle of the letter D. The bicycle option must be held with two hands, and tight.

Despite the presence of rubberized handles, it is better to rely on yourself and not hope that they will not slip. Keep the handle in the shape of the letter D with one hand, and with the palm of the palm to provide a large capture area. This will give you full control over the handle, which will positively affect control.

Rules of mowing

In order to cut the lawn with high quality and quickly, you need to observe the equipment and know some features that will save your time and effort. You can work faster, now we will tell you how.

Divide your site into zones. This will help you understand how much you will need to complete. Also, you will have no misconceptions in whether you have already worked here and do you go through the second again. For the first time, the lawn is mowed at a level of 4-5 cm, gradually reducing to 3-4. Install the norms of mowing yourself. You can leave more, smaller. It all depends only on you.

The disadvantage of electric trimmers is that if you mow vegetation during dew, then water can enter the motor of your technique.

If the motor is located below, then the probability of moisture will be even higher. It is also not recommended to work with a trimmer during the rain all due to the same reasons. Entering water can cause a short circuit, which in the future can develop into a malfunction of the unit. Therefore, it is better to wait for the weather more favorable for work.

It is recommended to work clockwise. It is this direction that will leave the grass you mowed by the outside of the entire mowing site. While hold the coil at least 5 centimeters. This is a safe option for a mowing that is good for those who have recently started using such an inventory. If it comes to work at the fence or other places where only a small part is required to mow, then use the edge of the fishing line. This will contribute to the fact that the engine will not overload and wear out.

Under hay

Use as a cutting element of a disk, because meadow vegetation is tougher than usual. It is better for the fishing line precisely for hay by cutting dry grass better. Thus, the grass will not get stuck on the fishing line, which can lead to the poor operation of the engine. Hay does not need to be cut small, it should be quite high, so try to mow hay under the root.

Even lawn

To create a flat lawn surface, try to process the greens of garden equipment as low as possible. So all the grass will be the same in height, which will make the coating even and beautiful. Do not forget about the inclination. For the best result, tilt the device at least 30 degrees to the surface of the grass. It will cut the grass as low as possible. Any other irregularities can be removed using garden scissors if they are available.

Spinning high grass

Particular attention is required here. High grass needs more thorough processing than simple. The fact is that there is an effect of wrapping vegetation on the reel. In this case, the grass remains on it and does not allow the mechanism to rotate in full power. This noticeably inhibits the process and reduces the number of revolutions.

So that this does not happen, go through the way in several stages. Gradually cut a certain amount in height, passing lower and lower along the stem.

As a rule, in high green the base of the stem is much thicker and stronger, so in addition to winding you can damage the cutting element with hard stems.

It is also necessary to take into account the fact that if your technique works recently, then mowing high grass may be even more difficult. Therefore, do not work for a long time so as not to give the motor a particularly large load. It will be enough for 15-20 minutes with a break for 15 minutes. Since it is better to mow grass in several stages, do not forget about the grass collector. He will begin to clog very quickly, this will lead to problems with the tool. Clean completely so that not too little time passes before the next cleaning.

Signs of common faults

Knowing the internal device of the lawn mower and the principle of its operation, you can easily eliminate the malfunctions with your own hands. Some breakdowns are most often found and they are distinguished as the main.

• The engine malfunctions should be sought if the lawn mower does not work or does not even start. It is also worth paying attention to this part of the braids for grass, if during operation unusual noises are heard or strong vibration is felt. Clotting of the air filter can also lead to problems with the engine.
• If the fuel does not enter the combustion chamber, then you should look for the cause in the suction of the fuel filter. It is also worth looking at it if the tool does not work at low speeds.
• The starter’s grille was clogged. the reason for the engine overheating and its termination. The starter can also fail when the cord tears when it is too sharp.

Malfunction. the knife does not rotate, the coil.

The reason is the wear of transmission elements.

The data transmission of the gasoline consists of a lower gearbox, shaft and upper gearbox (cup). Consider them in more detail.

The gearbox consists of a housing and a gear pair that are susceptible to wear.

This is due to the lack of lubrication in the gearbox.

Do not neglect this procedure during the operation of the lawn mower.

Lubrication control will extend the life of the gearbox.

There are sets of gears for these reducers on sale, but their cost exceeds 60-70% of the cost of the gearbox, moreover, the process of their replacement is laborious, a simple solution will be-replacing the gearbox with a new.

The transfer of traction from the engine to the gearbox is provided by a hard shaft, at the end of which there are slots. Due to the lack of lubrication in the gearbox, slots can be worn out. In this situation, only replacing the shaft with a new. Please note that there are 3 types of shafts (7 slits, 9 slits and “square”). The length of the shaft, as a rule, on such models 152mm. The replacement is very simple. we dismantle the old shaft. install the new.

A clutch cup is installed in the upper gearbox, on which there are slots under the shaft.

In case of wear, it will require its replacement.

The cup can be replaced both separately and the upper gear.

To remove the cup, it is necessary to remove the locking ring (p.49), catching his “ears” in the holes of the cup (n.48).

Please note that on the cup there are also options for the shaft (7 slots, 9 slits and “square”)

Clutch of a gasoline trimmer for grass

The knife or coil at idle rotates (subject to the “correct settings of the carburetor)

With such a malfunction, you will need to replace the clutch spring, or the adhesion assembly.

To replace the clutch, unscrew the upper transmission gearbox. Then unscrew the spark plug and suck the movement of the piston with a special stopper. Unscrew 2 clutch mounting screws (p.57) with washers (p.56), remove the clutch assembly and the washers under it (p.53). Change the spring on the clutch, or install a new. Do not forget to install the washers (p.53) then clutch, and twist the bolts (p.57) with engraver special washers (p.56).

How to disassemble a gearbox of a trimmer for grass

In order to disassemble a trimmer gearbox for grass, you need.

• Remove the gearbox from the pipe, loosening two conjugate bolt under the gearbox.
• Wash the gearbox with a brush, for example, in gasoline without oil and dry.
• Run the ends of the locking ring and take it out.
• The second stop ring and the second.
• Then it is necessary to heat the trimmer gearbox for grass, the motorcosa gearbox or the reducer of the lawn mower by an industrial (technical) hairdryer at the temperature of the outgoing air at 600 ° C.
• After that, strong blows of a wooden bar on the upper part of the gearbox, knock out a driven shaft with a bearing and a gear (first you should try to knock out bearings without heating). It is only necessary to hit a wooden bar, since a metal, for example, with a hammer, can be broken down by the case.
• In the same way we remove the leading shaft with a bearing and a gear (we strongly heat the place where the bearings are sitting and with the blows of the wooden bar on the body of the shaft, we knock out the shaft with two bearings and the gear). How to disassemble a trimmer gearbox for grass, gearbox gearboxes and gearbox motokos. In order not to heat, you can try to use the set.

The assembly of the gearbox of a trimmer for the grass is carried out in the reverse order of disassembly (assembly after buying and replacing spare parts). It is much easier to collect a gearbox than to disassemble. everything is going, literally, with fingers. Sometimes you need to gently take up something, install stop rings and check whether the driven shaft is spinning by hand.

If you decide to replace the trimmer gearbox for the grass with not original, then in the new gearbox you should pay attention to the diameter of the pipe for which the gearbox (more than 25.4 mm or 26 mm) is intended, the diameter of the drive shaft (more than 8 mm), the size of the square shaft square (more often 5 mm or a star for 9 teeth) and security mounting on the gearbox, as well as on a nut (with left thread, more often M10x1.25).

Engine malfunctions

If the failure of the trimmer for the grass is associated with a non.working engine, then in this case the owner will not be so easy to understand that it caused a problem, and how this can be eliminated. It is good if the device still has a warranty, in this case we can attribute a trimmer for the grass to the repair workshop, whose specialists will quickly and qualitatively cope with this task. Among the often identified and least related to the elimination of the causes of the engine formation, the destruction of the piston rings should be called. You can verify this by extracting the cylinder head and piston.

The owner of a gasoline or electrochemmer always needs to be prepared for the fact that at a certain moment this equipment will need repairs. At the same time, the contact center is not always the right decision. Often the causes of the malfunction can be quite simple, which can be eliminated at home. The main thing is to know where to look for her.

However, it is best not to solve such problems, but to prevent their appearance. To do this, follow the recommendations of the manufacturer for operating and caring for a trimmer. Then the situations when you have to think about the repair of a gasoline or electric trimmer for grass will occur much less often. And this will help the owner to save a lot of time, effort and means.

Trimmer repair for grass for grass with your own hands: Frequent causes of breakdowns

A trimmer for grass may fail when working in conditions of increased loads. This situation may arise when the processed area is overgrown with high grass.

When working in such areas, the engine may fail, a breakdown of bearings occur, as well as the coil of the electric ships to collapse. When working in rainy weather or in a strongly fog conditions, a trimmer for grass can “burn” as a result of a short circuit formation.

Damage to this electrical device can occur as a result of frequent use. If the household appliance is used in this mode, then after the development of a certain number of motorcycles, it will be necessary to carry out mandatory repair and preventive setting of many parts of the electrical device.

Repair of the launch button

If the electric coser does not show signs of life, then perhaps there was a break in the electric cable inside the handle of the case, or the button for turning on the electric motor is faulty.

In order to diagnose electricians, you need to disassemble the electrical appliance handle. The work is performed in the following sequence:

When access to the inner part of the electric ships is provided, using the multimeter, measurements of the resistance button for turning on the electrimmer are made. If there is no resistance after pressing, then this

The detail is subject to mandatory replacement. It is also necessary to check the locations of the power cable with the internal electrician located in the handle

device. Contacts should be checked “for a cliff” using a multimeter. Often such a malfunction can be determined “by eye”. After detecting the contact of the contact, it is enough to solder the damaged place to restore the operation of the electrimmer.

In the absence of a multimeter, diagnostic work can be done with an indicator screwdriver. For this purpose, you should include a fork in an electrical network and using this diagnostic tool

Find the “phase wire” and thus check the presence of electric current to the power button and after. If the phase current is detected in another electric circuit, then it is enough to install an electric fork on the contrary in the outlet so that the correct diagnosis can be carried out

trimmer malfunctions for grass. The second diagnostic option should be done with great care, t. to. There is a danger of electric shock while checking the integrity of the wiring.

Checking the electric motor

If the button for turning on the device and the sections of the internal wiring turn out to be intact, then you should proceed to check the electric engine. For this purpose, it is necessary to remove the cover cover, having previously unscrewed a few screws with a screwdriver.

The first thing to do after access to the electric engine is to check the operability of the brush unit. If the brushes are worn out over the maximum permissible value, then the electric motor can completely stop or work unstable. In the case when the brushes and the collector are in perfect order, you should proceed with the “call” the engine winding. In order to exclude the likelihood of a breakdown in both contours, one should alternate

Checking the stator and engine rotor. To perform this operation, it is necessary:

• Remove the engine from the electric ships.
• Turn on the multimeter in the resistance measurement mode and check all the collector plates for the break. When checking, there should also be no significant deviations in the testimony of the diagnostic device.
• Check for a breakdown of the rotor winding per mass. For this purpose, you should connect one multimeter probe to the “mass” of the rotor, and the other to any collector plate. The multimeter should be installed in the resistance measurement mode of more than 1 MOM. The resistance of the working engine between the winding and the “mass” should be very large.
• Measure the stator winding resistance indicator. If the resistance is absent, then in this case its malfunction can be stated in this case.
• If the stator wiring is in perfect order, then it is checked by a possible breakdown on the case, in the same way as in the diagnosis of the stator.

When checking in this way, it is possible to establish the cause of the malfunction of the electric motor in 90% of cases. Carry out a check for an interval circuit, which can only manifest itself in the process of engine operation, in this way it will not work, but you can diagnose such a malfunction

According to indirect signs, which are manifested in reducing the power of the electric motor and overheating. If the electric motor is equipped with a thermorele, then such an electric cos, with an inter.flip circuit, will work for a short time, after which the trimmer will automatically turn off the grass. In some cases, the thermorelele can cause a malfunction of the trimmer electric motor for the grass, therefore, in the complex of verification

events should be included “calling” the thermallane using a multimeter or tester.

It is very simple to do this: in good condition, an electric current passes an electric current in a cold engine, in

The electrical circuit will be opened faulty.

The problems of performance of the electrocos associated with the cliff of wires are easily eliminated by swinging contacts, but if the motor “burned out”, you will need to perform a complex rewind process that can

perform only a qualified specialist. In many cases, it is much easier and cheaper to purchase a new engine and install it in the place of burned. This work can be done independently

If the electrician of the trimmer for the grass is in good condition, then you should pay attention to other types of malfunctions that can manifest during operation of the electrocos.

Cutting part of the motorcycle

Regardless of the manufacturer, almost every model comes with fishing line and steel knives.

The transverse section of PVC Lines for a trimmer for grass can vary from 1.5 to 3.0 mm.

Made from a durable polymer, during kosba it is subjected to intensive wear and, as a result, a break. Therefore, from time to time it is necessary to check the presence of a fishing line in the head and, if necessary, replace it. It is recommended to purchase an additional bobbin for quick replacement with a reel with a fishing line ending.

Electric trimmer for grass vibrates

Many mowing users noticed that some time after the start of the apparatus, it begins to vibrate very much. On some trimmers, mainly in models more expensive, an anti.vibration system was installed in the form of shock absorbers seized between the engine and the bar. But in some cases, even she does not save from strong vibration. The reason that strong vibration appears in the trimmer, there may be a small amount or complete absence of lubrication on a hard or flexible shaft located inside the rod of the apparatus.

Replacing the lubrication of the hard shaft is as follows:

• Apply a small amount of lubrication to the shaft and evenly smear it along the entire length of the part, including the slots at the ends of the rod (if they worked, the shaft will have to be replaced);
• After lubrication, insert the shaft back into the bar and put the gearbox in the same place.

The lubrication of the flexible shaft is as follows:

• unscrew and remove the mowing head;
• remove the bar from the electric motor by unscrewing a couple of bolts;
• Pull out a flexible cable from the bar;
• Lubricate the cable with grease along the entire length.

This is done like this: first you need to lubricate the end of the cable, and then insert it into the bar, after which, as it moves into the pipe, you should apply grease to the part and evenly distribute it on the surface. Then insert a bar with a flexible shaft into an electric engine and fix it.

In the event that the lubricant did not help, and the vibration continues to appear, you will need to change the flexible shaft.

How to choose?

To navigate when choosing an electric trimmer for grass on ratings and reviews, of course, you need. But no less important is objective technical information about products. First of all, you need to watch how complicated the situation is on the site. The light apparatus will be able to cope, of course, with the maintenance in the manner of well.groomed lawn. But in front of a wild storm he will be powerless. The total area of ​​the cultivated territory should be taken into account. In very large areas, only powerful trimmers for grass can be quite effective.

Important! If you plan to serve a large territory, it is advisable to choose models with shutdown sensors.

Independently to track excessive heating of the working parts is not always obtained. And when overheating, their resource is significantly reduced, so a small overpayment for automation is quite justified.

For a summer residence with a very modest area (and for a 2-3.s) there is enough trimmer for grass with a lower motor placement with a total capacity of 0.3-0.4 kW. Such a device will help restore order directly next to the house, fence, flower beds. Small trimmers for grass (namely such models with the lower motor) allow you to put a working surface at the right angle. Therefore, they cope with work even in the most inaccessible places. But it must be understood that the lower location of the electric drive means insufficient reliability of the device. It can fail when working immediately after a heavy rain or in the pouring meadow. But for women, old people and adolescents, this option is optimal due to their lightness and mobility.

As for devices with the upper placement of the motor, these are not just reliable and reliable models. Only they can effectively cope with heterogeneous vegetation. The experience of many people suggests that only a trimmer for grass with an upper engine with a capacity of 0.9 kW can put things in order in a summer house. It is also necessary to take for this case a product with the though thick fishing line.

Count on the installation of a thicker fishing line than the instructions should not be. The common recommendations “reduce the work cycle and carefully monitor overheating” do not help or help very little.

It is recommended to pay attention to the arrangement of the rod. On low.power trimmers, it has a direct performance and not too long. Such a solution will appeal to women. But if there is no specific user (a trimmer for grass is bought for an organization or for a family), it is advisable to use models with telescopic rods. They are much easier to adapt to personal needs.

Monolithic bends in the lower part of the rod are used on trimmers with a capacity of 0.65 kW and above. As for the mowing strip (0.23–0.45 m), the larger it is, the more productive the device. Battery models of trimmers are mobile than network, but less convenient to work. Will have to carefully ensure that the battery does not discharge. In addition, when the charge drops below 30%, the capacity of the work drops sharply.

Operation Rules

Determining the rating model and technical characteristics is not enough. It is important to know how to use the purchased device. There is nothing complicated about this. you can start mowing grass immediately after purchasing, taking care of only a good lubrication of the gearbox with a lithol.

Important! Stretching the cable, it must be checked so that it is not in the way of the car.

It is extremely desirable to remove the garbage and stumps, pieces of glass, stones and other hard objects from the entire cleaned area in advance (and for reliability. and from the adjacent area).

During work, other people and pets should not approach the electric trimmer. Even at a distance of 10-15 m in the eyes and respiratory tract, thrown particles of mulch can fall. And getting them on the skin, clothes are also unlikely to be pleasant. For the same reason, they advise mowing grass, moving away from buildings and cars, and not vice versa. Excessively approaching fences, walls and other structures is inappropriate also because this can lead to a breakdown of the cutting device.

Playing an electric trimmer for grass is not difficult. When commissioning, it is simply launched and disabled 3-5 times in a row. This is enough to determine how easy it will be. If everything is in order, a trimmer 5 minutes work on a lawn grass. With everyday operation, it is worth focusing on 20/20 mode.

The belt is put on a completely assembled and prepared device. Then the belt adjust to their anatomical features. If everything is done correctly, the hands will not get tired. But when such fatigue appears, especially if there is also unpleasant vibration, it is better to stop and change the position of the belt. This adjustment is repeated until the slightest inconvenience disappears.

The belt in any position should be tightened to the end. Lawns are usually mowed according to conditional squares, which are more likely mentally. Move clockwise, which allows you to exclude problems during manipulations. To pump out vegetation under the root, they work, touching the surface at an angle of 30 degrees or more. The lower the fishing line for the trimmer, the more even the result of the haircut will be.

Important! Grass on the hay is mowed by a trimmer strictly under the root. Otherwise, it will be crushed, collecting a bracket will be almost unrealistic.

Having met a large weed, the space around it is shook. After the rest of the work, all weed plants are removed with their hands. If there are a lot of them, use more powerful mowing equipment or change the fishing line for a trimmer to the disk. High grass is usually mowed in two directions. In the first passage, the tops of plants are removed, and in the reverse passage the bar is already located at the desired height. If the thickets are very powerful, you have to make several right and several left movements on each row. Kosba of tall herbs immediately under the root is impractical. wrapping long stems on a fishing line for a trimmer will stop the work for a long time.

Important! In raw weather, especially during the rain, working with an electric trimmer is strictly unacceptable.

Mechanical malfunctions

In electrocos, the most loaded mechanical elements can be called bearings and a trimer coil (spool). In most cases, the device stops mowing grass due to the failure of its coil with a fishing line

The line for a trimmer ended. According to the instructions provided, you should wind the fishing line for the trimmer to the coil.

Finding a fishing line for a trimmer. If the coil has not received damage, then you need to cut or unwind the fishing line for the trimmer and, if necessary, rewind the entire rogue.

The fishing line for the trimmer was sticking together. Due to rather intensive work and large overheating, plastic threads of the fishing line can be fused with each other. It is necessary to rewind the coil with a new fishing line and inspect damage to the squash itself.

The engine works but the coil with a fishing line does not rotate. Most likely there was a damage to the structure of the coil with a fishing line. The attachment places of the bottom of the coil can be broken off, you need to completely disassemble the bobbin and, if necessary, finalize the mount or completely replace it. In most electric trimmers, the bobbin is simply pressed by its plastic case on the engine shaft and with strong overheating, when melting plastic, it may turn out and completely fly away.

Both devices did not show any signs of life, the engines did not work in the state on the state.

The case in both devices consists of two halves, the screws are on one side that is convenient in disassembly. After all the screws are unscrewed, the upper body is separated from the bottom, lightly with a flat screwdriver in a slot to open the closed plastic locks.

After disassembly, we proceed to the inspection of the insides and the search for faults.

During the inspection, a Bosch trimmer was found on a trimmer engine, on one of the brushes that is fixed by a clamping spring, a copper conductive wiring flew off, which was naturally the reason for the lack of voltage on the brushes and the engine did not rotate.

The wire was restored in its place, and along the way, the collector’s sites were cleaned, with a soft rag of wetted alcohol, to a copper shine. The brushes were in good condition and did not need a replacement.

It was also found that the switch did not create a reliable electrical contact, I had to clamp the button with an effort, it was decided to disassemble the button, its contacts were cleaned from the carbon and lubricated by the Kontakt S-61 with a current-protection spray.

It was not so simple with the Gardener electric carcass, it spent not enough time in a broken state, and in the literal sense of the word “broken”, its bar in the place of attachment of the engine body was broken in half, apparently so difficult conditions of its operation were so difficult.

With the help of the oenic plates from the fasteners, the thug of the profile was not cunningly made a new mount of the engine housing to the Elektokosa rod. The integrity of the design is restored, albeit not aesthetic, but in a reliable way, because in an electric cost of its main functionality.

The engine shaft of the engine was noticeably hard, during an internal examination, burnt outputs of the collector and worn brushes were found. The plates were peeled with the skin to shine, and the brushes were replaced with new.

In view of the long work without lubrication and the subsequent storage of the device in an aggressive environment, the bearings were a little flooded and the engine shaft did not naturally rotate with difficulty. The engine bearings were washed with a WD-40 spray with subsequent grease. As a result, the engine began to rotate noticeably better, but nevertheless the bearings were already “broken up” and when working the engine from the network, the sound of its work was not so smooth and monotonous.

The further inspection of the electric part led to the button, it was completely broken from its mounts, although it was pressed, the tester showed its malfunction. The button is not collapsible, therefore, it was replaced by a new. The fastenings had to be restored by thermochery.

In addition to a broken bar, there was a crack on plastic protection, apparently someone did not drop it weakly. A braid for grass could work with it, but it was decided, as far as possible, to restore the defense design.

Naturally, just glue with glue such a loaded and prone to hit the object was not a reliable solution. Therefore, with the help of the same surveyed plates, two brackets were made that created a “monolithic” connection of two parts of a cracked case from. The plates were connected to the body using aluminum rivets.

When the lawn mower was assembled, it was found that the bar was poorly fixed in the places of fastening of the handle and turning, so the places of the plastic protrusions of the handle of the handle with the rod of the rod were additionally sealed with a strip of rag island. Now the design has no extra backlash.

The main most encountered electrocos and trimmers

In the coil (spool) ended the fishing line for the trimmer. Most of the spool feed the grid is semi.automatic, with a light blow of the tin button on the ground, the fishing line for the trimmer is fed to the output. If the fishing line for the trimmer is not served, then you need to remove and disassemble the coil. Spool and, if necessary, wind a new fishing line for a trimmer.

A fishing line for a trimmer can be too long because the blade that is recognized for pruning the excess line of the fishing line is dull or it is not at all. The length of the fishing line should be slightly less than the diameter of protection.

Big hum and vibration during the engine operation may indicate that bearings need lubrication or they completely spent their resource. The coil of the coil with a fishing line (spray) may also be cracking, its as well as its mounting place must be examined for the presence of cracks and damage.

Most electric motors in braids and trimmers do not have a speed regulator, with a reduction in the voltage in the network. speed and power are reduced. A coil with a fishing line may be wound incorrectly. Perhaps the revolutions are difficult to the presence of a stuck twine or a rope was wound on the shaft, the structure should be examined. In a working spit, the shaft should easily and without the slightest effort to turn even after it was dispersed.

The engine does not rotate? We look at the availability of power on an electric grinder, if everything is in order, then the device needs to be disassembled. If no obvious damage is noticeable, then the sequential call of the electrical circuits of the device begins.

Using a multimeter (tester), they first nickname the power cord, the fuse if it is and the button. If the button is not nicknamed in the state, then it should be replaced or if it is collapsible, then open and clean the burnt contacts.

The cord can be interrupted, in which case the engine can be launched with interruptions. The engine malfunction can be the fact that when the button is turned on on the engine contacts there is a voltage of 220 volts, but it does not rotate.

Some electric motors are equipped with a thermal fuse that is built into the engine housing and worked from its overheating or simply failed. A working thermal fuse when cooling the engine should restore its work.
