Hooper coil for a trimmer for grass how to disassemble. According to the material

Learning to correctly wrap the fishing line for a trimmer to the coil of a trimmer for grass and lawn mowing instructions for installation

Owners of private houses know how necessary the type of tool is such as a trimmer for grass. It can be gasoline and electric, and they differ in the design of power units. For injection of grass in areas where there are stones, trees and other obstructing objects, a fishing line for a trimmer is used as a cutting device. This consumable in the process of use wears out, so how to wind the coil of a trimmer for grass, we will consider in detail in the material.

Fishing lines is called consumable, which consists of nylon, and serves as a cutting device. Through this equipment, the grass grows, which is ensured due to rotation of the instrument head with a high frequency. This material has a different thickness, which depends on its use on the corresponding tools of low-power (from 1 to 1.6 mm), electric from 500 W (2-2.4 mm) and gasoline trimmers for grass with motorcycles (from 2.4 up to 3.2 mm).

The more powerful the tool, the accordingly there should be a cutting equipment. This affects not only the quality of the injection of grass, but also on the life of the material. If you ask the question of how to wind the coil of a trimmer for grass, then it’s time to change the reload of the tool. With the onset of spring, this issue is becoming more and more in demand, so it’s time to understand the step.by.step instructions for replacing the fishing line in the coil of the trimmer for grass.

How to remove a coil from a trimmer for grass and extract a fishing line for a trimmer

Initially, before filling the fishing line for the trimmer to the coil of the trimmer for the grass, it is necessary to extract it from there. Coil or tip is a device that is located inside the braid, bobbin or drum. The heads are of different types (depending on the manufacturers), however, the principle of replacing the fishing line on the coil has the same. First of all, we will figure out how to remove the head from the tool, as well as how to get a drum with a fishing line from it.

It is interesting! The replacement of equipment can be done directly on the tool, but if you do it for the first time, it is still recommended to remove the head, and study the detailed process of winding. After the technology is mastered, you can perform work on replacement on a trimmer of a motorcycle or a gas station.

Instructions on how to promote a hand head on a trimmer, has the following look:

This process is not difficult, and as you know, it is not necessary to dismantle the entire head if you know how replacement is performed. When dismantling, consider the following nuances:

• It is recommended to remove the head periodically to prevent the corrosion of the threaded connection. If you never unscrew the screw, then if necessary to do it will be difficult and even sometimes impossible
• If the screw has a tetrahedral boring of the head, then for twisting you should select a screwdriver or bit of a suitable size to eliminate the licking of the faces on the head
• When assembling the installation, a threaded seat should be treated with lubricants, for example, solidol or machine oil
• If the edges on the screw are licked, then for its unscruptions you can use special clamping forceps
• There are drums that do not require preliminary disassembly. To dismantle them, you should take up it, and rotate in the opposite direction of the direction of the clockwise

Knowing how to disassemble the drum, you should continue to clarify the process of replacing a trimmer fishing line for grass. Below the video shows a detailed process how to open a trimmer coil for grass and disassemble it.

Types of heads for trimmers

A trimmer is a tool that is used to combat vegetation in a summer cottage or household territory. Grassing and hay harvesting for cattle implies the use of benzo or motorcycle. The heads of different types are installed on trimmers for the grass, through which the grass and other vegetation occurs.

The heads are classified into three main types that differ not only in design, but even in price, the method of operation and service life. Consider all types of heads for trimmers, as well as their technical features.

Necessary materials and tools

The indestructible nozzle for a trimmer for grass can be purchased at Aliexpress. But you can not overpay and make the same, and maybe better detail, with your own hands. This homemade coil for a lawn mower is suitable not only for fishing line, but also for a cable. This is very convenient and profitable, since the fishing line for the trimmer is heavily coping with thick plant stems and is consumed faster.

The presentation is based on the mechanism with the tape of the Bobin tape recorder. Many at home have old tape recorders, so problems with the search for spare parts should not arise. It will also require a protective casing from a car rack, which will act as a cover, a metal washer and a hexagonal nut with left thread.

For work, such tools and materials will be required:

Additionally, you will need a ruler, nippers, a key and some other auxiliary tools.

Removing and disassembling the coil

The braid trimmer head consists of a casing, a spring (not in every model), bobbins with a cord, cover. Before proceeding to disassemble the coil of the electric unit, be sure to turn off the trimmer for the grass from the network. The disassembly method depends on the mounting of the mowing head. First option:

• To remove the lid covering the inside of the head, click on the latches (latches), which are located on its two sides.
• Remove the lid under which you will see the spool. remove it from the body. Some trimmers have a spring under the bobbin coils, which should also be carefully pulled out.
• Removing the bobbin, you will see the screw in the center of the case. Unscrew it with a screwdriver.
• After extracting the fasteners, take the case body and, shaking it in different directions, remove the gearbox from the shaft.

In the second version, the head of the trimmer for the grass is twisted onto the shaft of the gearbox. To remove it, you need to fix the shaft. To do this, in such devices there is a hole through which a thin screwdriver or metal rod is inserted. Brief Instruction:

• Insert a screwdriver into a special hole, then stall the shaft.
• Get the body of the head and start twist it. This should be done clockwise, t. to. Larva shaft thread.

Winding of fishing line on a reel

Instructions with a step.by.step description how to wind the coil of a trimmer for grass and lawn mower

In order not to make a mistake with the choice of a suitable fishing line for your tool, you should first disassemble the head and look at the side wall of the coil. This information is usually presented on a tip, which will not allow us to make a mistake using the appropriate equipment.

If the information on the coil about what diameter the fishing line for the trimmer can be refueled, then this information can be clarified in the instructions. Having decided on the thickness or diameter of the equipment, it remains to figure out how to charge it. There are two ways for this, but not for all they are applicable. Consider both methods in details, and already depending on what models and trimmers you use, you are determined on your own which option is suitable.

It is interesting!The principle of how to wind a fishing line for a trimmer for a tip of motorcycles is appropriate not only for autonomous benzar groups, but also for electric trimmers.

Method 1. how to correct the fishing line for a trimmer or put it on a coil and choose the required length

To implement this method, you will need to pre.prepare a fishing line for a trimmer of the required length (usually up to 4 meters). It all depends on the thickness of the equipment used, as well as the design of the coil. There is a simple way to find out the required amount of fishing line, the refueling of which will be needed to charge the coil. To do this, the equipment should be wound inside the coil until it is equal to lateral protrusions. At the same time, the equipment should not go out for these extreme ledges.

The thicker the equipment used, the less its length will need and vice versa, the thinner, the longer the segment will need.

Instructions on how to properly tie the equipment into a tip of a trimmer for grass or motorcycles is the following look:

• To begin with, a segment of the fishing line, which was prepared to install in a coil, must be folded in half. In this case, one edge should be more than the second by 10-15 cm
• After that, the second end is taken from the other side, and doubles. Move to it so that the measured ledge 15 cm is preserved
• There is a slot in the internal partition of the coil, into which the resulting loop should be brought. The slot in the wall is shown in the photo below
• Next, find out the direction of the winding of the fishing line. If you wrap the equipment in the wrong way, then it will not function correctly, and you will need to redo the work. To insert a fishing line for a trimmer, and wind it in the right direction, you should examine the surface of the coil. It should indicate the direction of winding (in 99% of cases this direction is indicated). What does the direction indicator look like on the coil shown in the photo below
• This indicator in the form of an arrow can also have a designation, as an example above “Wind Line”, which means the direction of winding. If the arrow indicator is absent on the coil, then you need to look at the head. There is a direction of its rotation on the head, and in order to correctly wind the fishing line for the trimmer, you should wind it on the drum in the opposite direction of the indicator of the arrow pointer. So, if the shooter is on the tip, then you need to wind in the indicated direction, and if it is not there, then you should wind against the direction of the arrow on the surface of the head
• Having decided on the direction of rotation, you should proceed to the winding. Each end should be carried out in its groove. If there is no separator, then the equipment is necessary in the corresponding distribution order
• When almost the entire fishing line for the trimmer is wound on the coil, you will need to perform the following-place a short part in the hole of the side wall of the tip, which should be up to 10-15 cm, and then similarly to do the procedure with another end, placing it in the holes from the parallel side
• We insert the coil into the head, pre.letting the ends of the fishing line into the holes of the drum
• We install the drum in place and, pulling the ends of the fishing line, remove them from the engagement with temporary clamps in the coil wall. After that, you can put on the lid until the latch is triggered
• On this, the process, how to replace a fishing line for a trimmer on a trimmer, is completed, and if necessary, only the ends can be cut (if their length does not suit), and install the drum in the assembled form on the tool

With how to put the drum in place, no difficulties arise. There is a second way to charge mowing equipment into a motorcycle. How is it different, and how the second method of refueling the fishing line to the coil of motorcycles is carried out, we will find out in detail.

The device is a trimmer head

Semi.automatic trimmer heads are considered the most popular in the market. A typical representative of the mechanisms of this type is a universal semi.automatic head, which is equipped with electric trimmers for grass and lawn mowers such well.known brands as Bosch, Huter, Husqvarna, etc. Its device is shown in the figure.

• Corps (pos.6) with a lid (pos.1), equipped with special eyes (poses.5) through which the cutting cord is displayed;
• Shpulya (pos.3), on which a fishing line for a trimmer is wound (pos.7);
• a pressing spring (pos. four).

There are other simpler heads.

Characteristic malfunctions and their independent elimination

Naturally, during operation, the owners of the trimmers are faced with certain malfunctions of mowing heads. over, they are most often associated with certain difficulties in pulling (lengthening) of the cutting cord from the coil. The most common causes of the lack of fishing line is its “bite” between the turns or sticking.

If the string is not served

In this case, the cause of the defect is incorrect winding of the cutting cord. A trimmer fishing line can be wound with insufficient tension, which helps to cross the turns together and confuse the string. When the coil rotates, the cutting cord under the influence of the emerging centrifugal force is delayed, which in turn leads to the clamping of the free end of the fishing line between the turns. To eliminate this malfunction, you need to dismantle the coil, disassemble it and rewind the string so that the turns lie down in even rows, pressing tightly against each other.

If the string sticks together

Squeezing of the turns of the fishing line directly in the mowing head can be caused:

Advice! To avoid sticking the cord inside the mowing head, experts recommend applying a thin layer of silicone lubricant after refueling the string to the coil. In addition, it is better not to use a fishing line for a trimmer of unknown manufacturers.

If, nevertheless, the user could not avoid sticking the fishing line, then to repair the trimmer coil for the grass, you need to remove and replace the existing cord with a better.

If there is too much string consumption

When using semi-automatic mowing heads, the user can detect the accelerated consumption of the cutting cord due to its spontaneous lengthening. As a rule, this happens due to the weakening of the spring installed inside the coil. You can eliminate the malfunction by putting several goals under the spring.

If the bobbin does not spin

The refusal to work the semi.automatic coil of the trimmer for the grass can also be caused by a frequent clash of its head with solid objects (dry branches, soil, stones, etc.). In this situation, there is a slight stretching of the fishing line, and then the rapid retraction of it inside the bobbin. Due to severe friction, the cord is heated, which can lead to sticking its turns to each other. To eliminate the defect, the string will need to be rewound.

If the string is served spontaneously

Spontaneous lengthening of the fishing line, followed by pruning its tips, may be caused by a violation of the order of assembly of the head after replacing the cutting cord. Often, users who do not have sufficient experience forget to install the pressing spring inside the head, which causes premature operation of the mechanism responsible for the supply of fishing line.

Dismantling the spit head

Starting to repair the head of the trimmer head for grass, the owner needs to protect yourself from injuries when randomly starting the engine, for which you must completely de.energize the electric garden tool or drown out the engine motorcycle engine. Most often, the owner of a trimmer for grass is faced with the need to replace the cutting cord. This process is started after the head is dismantled from the shaft. This must be done carefully to avoid damage it.

Important! The gearbox shaft, which is equipped with a trimmer for grass, has a left thread at the end, so the mowing head is taped clockwise when removing.

Dismantle the coil in the following order:

• Having combined the holes available on the axis and washer, the mowing shaft is rigidly fixed by means of a screwdriver or a metal rod;
• unscrew the executive mechanism, rotating its case clockwise.

Having removed the braid head, they begin to disassemble it, for which you need to carefully open the lid, which is most often attached specially provided for by plastic locks. To do this, squeeze the edges of the lid and at the same time drown in the hull of the latch.

Attention! If the trimmer for the grass is equipped with a semi.automatic head with a button at the bottom, then it needs to be opened by observing special caution, when removing the cover, a pressing spring can fly out and get lost.

Charging the string in the spool

To charge the fishing line for the trimmer correctly, it is necessary to act according to the instructions for the operation attached to the trimmer. As a rule, this operation is carried out as follows:

• cut off the right amount of cord and fold it in half;
• The resulting loop is inserted into one of the specially provided grooves (holes) of the spool;
• Pulling the fishing line for the trimmer, they turn the spool counterclockwise several times, while the coats of the cord should be laid in dense layers (one to the other), avoiding overlap;
• Having finished winding, the ends of the fishing line (about 20 cm) are left free, which are fixed in the grooves available on the sides of the spool;
• mount the mechanism in their place, for which it is necessary to assemble it in the reverse order, returning to its original position all the available details (spring, washers, etc.), and install the coil with a string in the body of the head;
• The free ends of the cord are passed through the existing eyes (holes), after which the body is closed with a lid, which is fixed with latches.

On this charge of the spitter head, the cord can be considered complete. The coil is screwed onto the shaft of a trimmer for the grass, having previously stiffly fix it. How to do this described above. You can check the performance of the head by mowing a small area of ​​the lawn.

Advice! In those cases when the owner of a trimmer for grass prefers to replace the failed head of the new one, experts recommend avoiding the acquisition of cheap non.original coils brought from China.

Problems with fishing line

Trimmeres users, both gasoline and electric, sometimes have problems with the cord. “Advanced” Kosilov owners can easily cope with the difficulties, realizing 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 to the fishing line are the following.

Cords of cord

If a trimmer fishing line is often torn, this can cause the following reasons:

• Stones, small branches and other hard obstacles come across the grass;
• The user mows the grass back to the fence, and if he is mesh, then this breaks the “antennae” even faster;
• poor quality of the cord (it is recommended to purchase high.quality);
• The output holes are worn out in a mowing head, which is why the fishing line for a trimmer is erased on the sharp edges of the bushings and breaks off (a complete replacement of the part will be required).

Large cord consumption

Basically, the cord quickly ends if you often knock on the ground with a semi.automatic head or press it hard. The coil unlock occurs, and the fishing line for the trimmer, lengthening, is cut off with a knife. Another reason that the cord quickly ends is the improper operation of the device with an automatic head: the user during kosbe often drops engine speed. But as we recall, the automatic head is arranged so that it is with each reduction in the revolution that a new portion of fishing line is supplied, so it is quickly consumed.

The thread does not hold

It happens that the thread is unwound if the spring weakened in the semi.automatic head. The fishing line for the trimmer is constantly extended and cut off with a knife installed on the casing, which increases its consumption. To check this, remove the casing and turn on the unit. If the fishing line for the trimmer “climbed”, then you will need to replace the spring.

a fishing line for a trimmer flies out

The reason that the cord after starting the unit is unwound is also a weakening of the spring inside the head. In addition, there are times when when the unit is turned on, a spitter head is scattered, and the spring installed in it is lost. Inexperienced users do not notice the absence of a spring and collect this node without it. Therefore, the cord does not hold, and under the influence of centrifugal force flies out.

The cord is not served, the coil does not spin

Automatic or semi.automatic head should serve a fishing line for a trimmer without stopping the unit. But if it does not come out, then the reasons may be as follows:

• The fishing line for a trimmer in a coil is incorrectly wound, which is why the latter does not spin;
• The cord is wound unevenly, and the thread can get stuck between the turns (the thread should be wrapped neatly, the turn to the turns, without distortions);
• Too short ends of the threads 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 for the trimmer (it is recommended to always adjust the length of the cord before starting the unit, slightly pulling it up);
• The fishing line for the trimmer is sticking together (it will be considered later).

The thread sticks together

This nuisance occurs most often due to the use of poor-quality cord. When the apparatus is operating, the head of the trimmer for the grass heats up, and a poor.quality fishing line for a trimmer in it melts, gluing among themselves. Also, sintering of the threads occurs when a fishing line with a solid obstacle occurs. In this case, there is a sharp braking of the cord, after which it drags it into the head, where it bothers. Some unit owners recommend lubricating the cord with mineral oil or spray on it with a silicone spray after winding on a spul. Others advise to wrap less threads on the coil. But it is better to immediately buy a quality product, in the manufacture of which the manufacturer took into account the factor of overheating of the head, and the thread will not stick together.

How to remove the coil and replace the fishing line for the trimmer

The owners of the trimmers, mainly beginners, confuse, bordering on panic, when it becomes necessary to change the cutting tool or fishing line for a trimmer in a reel. Very often, when trying to unscrew the mowing head, users simply make it unusable, not suspecting that it is unscrewed in the opposite direction. So that this does not happen, if you need to replace the tool, it is recommended to familiarize yourself with the step.by.step instructions given later.

• Before refueling the fishing line for the trimmer to the coil, drown out the engine of motorcycles or de.energize the ethletric trimmer for the grass to avoid injuries that may occur in case of accidental rotation of the cutting tool.
• Unscrew the nozzle mounted on the gearbox shaft. To do this, the shaft must be fixed by combining holes on the puck and on the axis, and inserting a metal rod or screwdriver into them.
• Unscrew the nozzle. You should know that the thread on the shaft is left. Therefore, to twist the coil of the trimmer for the grass should be right, that is, clockwise.
• Disassemble the mowing head. Most often, the head cover is attached to the fixers. To remove it, you need to drown these latches into the case, pressing the edges of the lid. If your trimmer has a semi.automatic mowing head, which has a button from below, then disassembling the nozzle should be done carefully, since you can lose a spring that sometimes flies away when removing the cover.
• Cut the required amount of fishing line. Usually its length is 5 meters. Use the cord of the diameter that is indicated in the instructions for the tool. It is not recommended to exceed the maximum diameter of the fishing line, since this will lead to increased load on the engine and greater consumption of gasoline.
• Find the middle of the segment of the cord, folding it in half. You will get a loop.
• Special grooves are cut out inside the coil (there may be holes). Insert the loop from the fishing line into this groove.
• Wind a fishing line for a trimmer to a coil, turning it counterclockwise. You need to refuel the cord as evenly as possible, the turns should be laid without ceiling and with good tension. When the winding is finished, leave the free ends of the fishing line about 20 cm long and fix them in the grooves located on the sides of the coil.
• Collect the braid head. Before you finally collect the nozzle, do not forget to insert a spring and washer (if it is available). Install the coil in the case, and prone the ends of the cord through the holes or eye.
• Dress the lid and fix it with latches.
• Screw the nozzle back to the gear shaft, also fixing it with a screwdriver. Tighten the coil of the trimmer for the grass will need to go to the left (against h. Arrows).

Replacing Magneto

To correctly purchase Magneto for replacement, you need to contact a specialized store or service center and name the brand and model of a trimmer for grass.

Advice! Another good decision will be the provision of an old ignition coil, according to which the seller will be able to choose a new part.

To remove the magneto, you need to remove the plastic casing from the trimmer for the grass. On different models of motorcycle, this process is different. It is usually necessary to unscrew the bolts, but on some benzotrimers it may be necessary to squeeze the latches. After that, access to the coil opens. To remove the part, you need to unscrew the holding fasteners and disconnect the wires.

When installing a new part, you need to correctly set the distance between the flywheel and magneto. To do this, you need to turn the flywheel with magnets up, install the coil and fix it, but the screws do not completely tighten, so that there is a short distance between the details. Further, between the coil and the flywheel, it is necessary to put a calendar, a business card or four.folded paper sheet of A4 format, you can also use a plastic strip cut out of the bottle. Such tricks will provide a suitable gap between the flywheel and magneto. A more competent solution will be the use of a special template, but it is impractical to purchase it for the sake of once. Next, you need to tighten the fasteners, remove the object between the details, and, holding the magneto with your hands so that it does not spin, tightly tighten the fixing screws. After that, you should crank 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.

There are many models on the market, but there are several manufacturers who have long gained popularity among gardeners.

Patriot DL-1200

This is a semi.automatic coil that is used to work with the Patriot trimmer. But also suitable for all benzotrimers with a direct barbell. The length of the length of the cutting strings is carried out due to a slight blow to the ground. Universal, for example, is considered Bosh K103. This coil weighs only 300 grams and is perfect for trimmers “Makita and Hyunda”. Differs in a solid fishing line and moderate consumption. The base of the coil is metallic and rarely breaks, and the head itself is automatic.

Denzel 96308

Great model for gasoline and electric trimmer for grass. Equipped with automatically feeding fishing. Made of shockproof plastic. Fishing line fastening method. winding.

Stihl Autocut C 5-2

This is a convenient model of a semi.automatic mowing head. Great for mowing in complex areas, near the walls, borders, and other small obstacles. In this model there is no need to disassemble the mowing head to replace the fishing line for the trimmer. All adjustment is carried out when the coil with the ground is in contact.

Trimmer coils are one of the main components of motorcycles. Therefore, when choosing this detail, it is important to pay attention to everything: manufacturing material, type of fishing line, and whether the coil is suitable for a specific trimmer model for grass. It is optimal to use universal coils that are suitable for several models of motorcycle. There is no opportunity to choose a head that is only suitable for your motorcycle. Most experts and users still recommend dwelling on semi.automatic coils, since this is the perfect ratio of price and quality.

Prevention of the problem

Often, the breakdown of the ignition coils are associated with the closure or cliff of windings and mechanical damage to the magneto body. This is due to strong blows, fluid and oxidation, as well as overheating. If you avoid such incidents, you can not worry about the integrity of the ignition coil.

Important! To prevent regular failure, one of the most important components of the ignition system, you need to refuel high.quality fuel. Bad fuel spoils these details.

One of the nodes of Magneto, which regularly suffer when using, are high.voltage wires through which current from the ignition module enters the candles. They have a high service life, but the damage to them is caused by users by an inaccurate circulation when replacing candles, carefully pulling the wire itself, and not for the tip. Another problem that can happen to them is moisture and oxidation or damage to isolation. If you carefully pull out the candle and avoid the penetration of the liquid into the device, these problems can be avoided.

So, the repair of the ignition coil is not very complex and can be carried out by the user independently, but subject to the above procedure for disassembling and replacing the magneto or contacts of the interrupt.

Why is the ignition adjustment

In some cases, when the engine does not start, the ignition adjustment will be required. Of course, first you need to check the serviceability of a candle and a high.voltage cable with a cap.

It is necessary to adjust the ignition on a two.stroke engine in order to ensure timely ignition of fuel in the engine combustion chamber. Below is a scheme from which you can understand the principle of operation of the internal combustion engine.

The spark in the candle should appear at the time of compression of the fuel with a piston, when it does not reach the upper dead point (VMT) at least a little. Когда поршень проходит ВМТ, происходит возгорание топливной смеси, в результате чего поршень под действием энергии взрыва уходит вниз.

Therefore, if for some reason (mainly this is due to the shift of the flywheel to the shaft relative to its original position), the fuel fire occurs earlier than the piston passes, then it returns back, and the crankshaft scrolls in the opposite direction. Such a movement can damage the starter knot, cut off the launch cord, etc.D. In this case, an early ignition of fuel occurs.

There may also be a later ignition on the trimmer: the piston after compression of the fuel, which does not ignite, goes down, and at that moment a spark appears. In this case, the engine will either not start or significantly lose power and will be poorly gaining momentum.

But such problems with early or late ignition on two.stroke ICE are quite rare, since the flywheel with magnets is already established in the correct position, which is perfectly synchronized with the movement of the piston. In addition, the flywheel is fixed on the shaft using a key and nut. Therefore, the wrong installation of the part is excluded.

Basically, the ignition adjustment is to set the correct clearance between Magneto and the flywheel.

Forest winding algorithm

The type, thickness and length of the mowing fishing line are selected depending on the model of the trimmer for the grass. The diameter of the cord can be from 1.2 to 4 mm. It is easy to guess that the thicker you are refueling the cord, the tougher and thicker it can be cut.

There are 3 ways to find out what kind of fishing diameter you can use on your mower.

• Contact the instructions of the device for information about the thickness of the cord.
• Look at the coil itself. It can be marked with information about the possible diameters of the mowing fishing line.
• Insert a trimmer fishing line into a socket. If it passes into it easily, you can use a cord of this diameter.

The fishing line for a trimmer is wound on a coil located in a mowing head. Therefore, it first needs to be opened (this was discussed above). There are two ways to wind the cord.

The first way

To correctly determine how many meters of fishing line is necessary for a specific coil, it is necessary to wind it on the reel so that the coil does not exceed the diameter of the boards. If the fishing line for a trimmer goes beyond the edges of the coil, you cannot insert it into the lid. As soon as you have decided on the length of the material, you need to load it into a reel, so do the following.

• It is necessary to fold a fishing line for a trimmer in half, so one end is 10-15 cm longer than the other.
• Please note that the coil is divided into 2 parts by the central side, with which charging begins. Find a recess on it and insert a cord into it, bent in half, with a slight effort.
• This is very important to determine in which direction the fishing line for the trimmer is wound to the coil. If you look carefully, you can find an arrow on the drum or an inscription with an arrow indicating in which direction to wind. There are cases when there is no arrow on the coil. In this situation, you can look at the drawn arrow on the mowing head and wind the cord in the opposite direction.
• The winding should be carried out carefully, wrapped with a reel, with maximum thread tension.
• After the cord is finished, you must first fix the short end of the mowing fishing line, inserting it into the groove of the corresponding diameter on the side of the coil.
• The other end, genuine, is installed in the groove on the opposite side of the coil.
• After fixing the spit line, cut its ends, leaving the allowances about 10 cm.
• Next, it is necessary to install an aged coil in a mowing head. To do this, insert and stretch the threads into the heads of the head, insert the coil into the housing, and then, applying the required force, pull the fishing line for a trimmer from the fasteners and tighten it.
• Now you can put on the lid and fix it with latches.

The second method

Some coils provide the second method of fixing the cord: instead of one folded in half, you can charge 2 pieces of thread for a trimmer is replaced in accordance with the following algorithm.

• Before replacing or loading a new thread in a coil, determine how many meters are required, as described above.
• Bend one end of the cord in the form of a hook.
• Find the hole in the bottom of the coil to fix the fishing line for the trimmer, and insert the end of the thread bent into the loop.
• It is necessary to wind the cord in accordance with the direction of the arrow to the desired level not exceeding the diameter of the coil.
• Do the same for the second coil nest.
• The assembly of the head is no different from the method that was provided for when refueling the coil considered with a double piece of fishing line.

There is a very simple and fast way to replace a fishing line for a trimmer without disassembling a mower that you can see by watching this video.

The ends of the cord protruding from the holes in the case can be cut to the required length when the part is installed in the trimmer. There are two ways to do this:

• The inclusion of a trimmer for grass (during rotation, the ends of the fishing line will be trimmed around a knife fixed for this on a protective cover);
• Cutting the extra ends with scissors so that they do not touch the body.

The second method is used if you need to put on a large diameter cord, and the cutter cannot shorten it.

If the thread is tucked on the mowing head, but the length of the protruding ends of the cord is insufficient, they must be lengthened before starting the machine. This applies to the head with manual adjustment. However, there are cases when a semi-automatic mower is used, when, due to the insufficient length of the protruding ends of the cord, they do not automatically lengthen. In this case, you need to turn off the unit (absolutely necessary to pull the fork out of the outlet on the electric device), manually press the button located at the bottom of the part, and pull out a little fishing fishing line for the trimmer. After this procedure, the cord will be able to again lengthen due to centrifugal force if you set the maximum speed of spindle rotation.

Replace the fishing line for the trimmer disk or knife

When finishing the garden, park zones and other places where you need to mow various types of plants, you often have to change the cutting tool in the trimmer. This is due to the fact that the standard cord installed in the head of the lawn mower can only work with grass. But when a shrub or a young sprout of a tree appears in the way of the worker, a fishing line for a trimmer does not cope with this task and should be replaced by a more effective cutting tool.

Trimmer manufacturers have provided similar situations and complemented their products with a mass of nozzles in the form of knives with several “petals” or in the form of disks similar to disc saws.

If you replace the fishing line for a trimmer with a knife with several “petals”, then this tool can mow both high grass and plants with thick and dry stems. And having changed the fishing line for the trimmer on the disk, the user gets the ability to cut bushes or small trees.

Knives and wheels are installed according to the following algorithm.

• First, remove it by fixing the shaft, the mowing head (turn clockwise) or a nut with a shoe if the unit has not yet been used.
• Set a saw or cutting knife so that they are placed on a small ledge (sleeve).

• Install the fastener on the knife and screw the nut to the shaft (counterclockwise).
• Tighten the nut (counterclockwise) using a pipe key.
