How to choose the right one?

Before purchasing this equipment, you need to understand for what purpose it will be used. For a large area with a flat lawn, it is better to purchase a light model with low power. If you need to equip a summer cottage, then you need to choose a more powerful model.

Trimmer mowing head

It is a special assembled coil with a cord inside.

The trimmer head is classified according to the line feed method:

  • Manual. In this case, the name speaks for itself, that is, the line is fed mechanically. To make the cord even longer, you must stop the trimmer and manually pull the ends.
  • Semi-automatic. If you want to replace the cord, the trimmer head needs to touch the ground. At the same time, a special button is pressed and the anchor mechanism opens. Further, the lengthening of the cord occurs due to the centrifugal force. The main feature is that the procedure takes place when the trimmer is on.
  • Automatic. To make the cord elongate, the engine speed is reduced. Further, when increasing them, the line is fed automatically.

From the foregoing, it follows that the manual mowing head for the trimmer is inconvenient.

What it is?

The trimmer consists of a cutting element, a bar, a motor and a handle with a control mechanism.

Cutting tool

To make the cutting process easy, you need to choose the right cutting element.


The main technical characteristics of the trimmer are:

  • power;
  • equipment weight;
  • type of power supply (from the network or using a battery);
  • engine location (top or bottom);
  • type of cutting element;
  • rod type.

All this must be taken into account, buy this or that device.

Classification by filling method

The trimmer head can have several ways of threading the line:

  • Quick Chargers. The new cord is wound without disassembling the coil, that is, there is no need to remove it from the device. The end of the new element is pushed into the spool and then wound a certain number of times. When a specific value is reached, the cord is cut. This type of trimmer head is available from Shindaiwa and Speed-Freed.
  • Collapsible. Here the name itself speaks for itself. To replace a new cord, you need to remove the spool from the equipment, then unwind the old line and wind a new one.

Trimmer head: types and description

One of the common devices for cutting grass is the trimmer. It is very easy to operate and maintain. That is why it has become popular among the population. Its significant advantage is its low weight. Even a child can handle such equipment.

Design features

It should be noted that the trimmer cutter head contains special arrows. They allow you to rotate the coil in different directions. If it becomes necessary to wind the line in the direction of rotation of the shaft, it turns to a specific position. A large amount of coiled cord can damage the equipment. The two arrows are only found on imported models. Single hand heads are currently on the market.

If, after the impact of the semi-automatic head, the cord is not wound, then its previous winding was performed incorrectly. That is, after the trimmer head was installed, the user did not pull the ends of the line out of the grooves. Another unpleasant moment when mowing grass can be the sintering of the coil turns.

For various models of trimmers, a semi-automatic head is used, consisting of two parts. a body and a spool. Both elements contain springs. The second part can be performed in several versions:

  • single-section. both parts of the line are wound together;
  • two-section. each end is wound on a specific part; this type is the most effective, since the line does not get tangled and does not bake.

There is a simple and cheap way to convert a one-piece spool to a two-piece one. This requires a sturdy plate. From it you need to cut a circle, the diameter of which should be equal to the thickness of the spool. In this case, the thickness is taken near the place where the line is wound. This circle moves freely. Next, a cut is made on the ring, put on a spool and connected with glue or tape.

How to tuck line into the trimmer: a few simple tips

Thanks to modern power tools, a person is given a lot of opportunities to reduce manual labor. These innovations include the trimmer, which greatly facilitates the process of mowing and lawn care. This device reduces the time for gardening work, turning difficult physical work into entertainment. The trimmer uses a fishing line as a cutting tool. It stretches strongly and thus mows grass of almost any height. It is quite easy to operate a power tool, but the problem arises when the cutting material runs out. Not everyone will immediately figure out how to tuck the line into the trimmer. Although this is a simple operation, it is not always clear to a person who is faced with this task for the first time how to properly wind it on a reel. over, the instructions do not contain information on how to choose and replace the trimmer line.

How to quickly and correctly tuck the line into the trimmer?

Once you figure out how to change the cutting material, further use and maintenance of the trimmer will be greatly simplified. To wind the trimmer line, several operations should be performed, namely:

  • Unscrew the nozzle by rotating the drum to the right. You will have a head with the remnants of an old thread in your hands. Open it with a screwdriver, or wring out the latch and turn the cover in the direction of the arrow. This operation should be carried out carefully, since there is a spring inside, which, straightening, can throw out all the internal parts of the drum. To change the line in the trimmer, you need to take out the spool and remove the rest of the material.
  • Take 5 meters of new thread and fold it in half. There is a hole in the middle of the spool where you need to insert the material. There is also an arrow indicating the direction to reel in the trimmer line. It is important to consider some points. If there are two holes in the spool, then half of the trimmer line should be tucked in one direction and the other in the opposite direction. When finishing inserting the material, it is better to leave 15-20 cm free.
  • Assemble the drum, reinstall the spring and washers. Then, while holding the spool, thread the ends of the line into the holes on the sides of the nozzle. Then put the head in place, pulling on the cutting material.

How to wind the line onto the trimmer spool

The line in the trimmer head can run out at the most inopportune moment when the work is in full swing. So that replacing the fishing line does not take much time and does not have to go through the instructions for a long time, we recommend that you theoretically familiarize yourself with this process in advance. From our article you will learn all the subtleties, starting with the choice of consumables and ending with winding on spools of different types.

Line replacement process

Line selection

For each trimmer, the manufacturer recommends a fishing line, or cord, of a certain diameter. a reel is made for it. It can be from 1.2 to 4 mm: you need to look at the instructions for what line sizes are acceptable for your tool. For example, many trimmers have a maximum value of 3 mm (recommended for tough grass). a thicker cord cannot be fitted. For mowing young, soft vegetation, a thin line with a diameter of 1.2. 1.6 mm is suitable. Also, when choosing, pay attention to the structure of the cord: round is the most durable and is suitable for coarse grass, curly. for soft, twisted or with notches. for thin stems. Depending on what kind of grass grows on the site. lawn or weed, buy the appropriate consumable. The length of the winding can be from several tens to several hundred meters, and its price depends on this. You need to proceed from the amount of work to be done. If the trimmer is used in a private household, there is no need to buy a roll over 100 m.

It is important to know! Buy only branded line recommended by the trimmer manufacturer. It is made of quality materials and is durable. it will cut the grass perfectly and not wear out so quickly.

For one threading of the line into the bobbin, a length of 2 to 4 m is required. it all depends on its thickness and the manufacturer’s recommendations. If you wind more, the movement of the line will be difficult, and in the process of work, you may have problems pulling out new ends. Unwind the required amount and cut with a knife.

Helpful Hint: Place a piece of cord in water for 30 minutes, then it will become more elastic and stronger.

Removing the spool from the spit

To insert the line into the trimmer head, remove it from the tool. Depending on the design, this can be done by pressing the latches or unwinding the lamb. Pay attention to the direction of the thread. right or left. and rotate the wing depending on this. Usually the direction of rotation is indicated by an arrow on the trimmer head housing. It is recommended to carry out this operation with gloves. fingers will not slip, and hands will not get dirty.

attach, trimmer, head

Dismantling the mowing head

The line is wound on a spool, which is hidden in the trimmer head housing. To get to it, you need to disassemble the element. On the case there are latches-latches, when you press them, the case cover can be easily removed. Sometimes disassembly is carried out by untwisting the case.

Be careful! Remember in what order the elements are installed, how the spring and the fixing screw are located inside the head. Stack all the parts neatly in one place so that nothing gets lost and there are no problems during assembly.

Line winding

Trimmer heads differ in structure, reel type and line pulling principle. Having disassembled the case, you will see the spool and determine what type it belongs to. There are products with a collar in the middle, which divides the reel into top and bottom parts for each end of the line. In products without it, the line winding is solid. To make the process clearer, we suggest using the table.

Winding line on reels of different types

With dividing edge

Without dividing board

We have described how to wind the line into the reel of a double-barbed trimmer. This is the most common option. But there are other ways as well. For example, if there is one antenna in the mowing head, then winding is carried out without folding the line. Rotate in the direction indicated on the bobbin body, and the free end of the cord is temporarily fixed in the slot on the body. For trimmers with four antennae, four short sections are consumable, which are inserted in turn into the holes of an already assembled head.

Helpful hint: when winding the line, be careful not to pull it tight, so that it does not sit very tightly in the reel. It is necessary to ensure its free movement for subsequent pulling.

Assembling the trimmer head

After the line is wound on the spool, it is necessary to assemble the body. Position the spool so that the ends of the line can be pulled into the outlets of the trimmer head. The slots in the spool where they were temporarily inserted will prevent them from slipping out. If there are no such slots, support the ends with your fingers as you insert the coil into the body. After pulling the free ends into the outlet openings, close the lid and secure it with latches or twist. Place the mowing head on the trimmer and pull out the ends of the line to the desired length so that they do not touch the protective cover during operation. Done! You can get to work!

How to wind the line onto the trimmer spool

05 July 2018

The trimmer is a great solution for those who have a large garden or lawn near the house that needs to be constantly trimmed. But like any other tool, sometimes it requires intervention. After some time, it will become necessary to replace certain elements, and this will have to be learned.

How can this be done? To replace the main cutting element, you must first select it correctly. In principle, the operator’s manual for lawn mowers should indicate the diameter of the thread to be used in it.

When you have acquired the required cutting element, try to install it correctly. It should be noted that there are a huge number of videos on the Internet that will help you figure out how to properly thread the line into the trimmer coil.

How to change the line on the trimmer

Below we have provided step-by-step instructions for replacing the trimmer thread.

The first thing to do is to unplug the tool and turn off the engine. Then you need to remove the trimmer head. This can be done using a simple screwdriver and dropping it into the hole of the gearbox to prevent the shaft from turning. And then just unscrew

They are usually unscrewed in a clockwise direction, but different models have different mechanisms, so it may have to be turned in the opposite direction. But if suddenly, for some reason, you cannot figure it out, then we strongly recommend that you refer to the user manual to understand how to disconnect it.

Second. After removing the mowing head, open it. This can be done by means of clamps that are located opposite each other. By pressing on them, you can remove the head cover, and then pull out the spool on which the line is wound. By pulling it out, you can determine what type it belongs to. There are one-piece and two-piece bobbins

We analyze how to thread the line into the trimmer spool in two versions

So, there is only one option. we load the line into a single-section reel. The prepared piece of thread is folded in half and pushed into the spool. Then, we begin to wind both ends in the same direction, which will be indicated by the arrow on the spool. At the end of winding, do not forget to make sure that different ends of the thread are looking in different directions.

Option two. winding the line with a two-piece reel. The pre-prepared thread is divided into two parts, and its ends must be fixed: this must be done by placing them in special fasteners

Winding is carried out, as in the first case, according to the arrow indicated on the spool. Both segments should be wound so that they do not intersect. Further, the ends of the thread should be fixed in the grooves and divorced on opposite sides.

The spring is then inserted into the reel and the whole thing is placed in the mowing head. When placing the spool in the trimmer, you need to gently hold the spring parallel while inserting the line into the slots on the mower head. And in the end, it just needs to be secured with the final part, that is, with a lid.

After threading the trimmer, you need to check it. If you did everything correctly, everything will work, but if you make a mistake, we recommend that you read the article again, or even better, if you watch the video on how to install a line on a reel in a trimmer.

How to remove the line from the trimmer reel

Over time, the cutting element of the head wears out, and it becomes necessary to pull out the remnants of the old line. Not everyone knows how to do this. Our step-by-step instructions plus a video on how to pull the thread from the trimmer spool, which you can find on the net, will help in solving this issue.

Hard ? Of course not. But if, nevertheless, doubts creep into you that for some reason you cannot do this, then of course find and watch the video how to pull out or how to wind the thread on the reel of lawn mowers.

How to replace the line on an electric trimmer

In fact, it makes no difference which oblique you use, be it electric or gasoline. Threading is the same. The only difference is that if you use a gas streamer, you get more freedom, since you are not limited by the cable that is present on the electric streamer.

Yes, do not hesitate to use the special videos on installing or threading the line in an electric scooter, which can teach you much faster than simple reading.

Uneven line winding

An option for repairing a spinning coil when winding with a cone upwards consists in adding another washer to the shaft, which compensates for the generated production. And in either case, the problem is eliminated in full, allowing you to wind the cord in the original, convenient for casting, originally and constructively laid down by the factory style.

Usually, the diameter, which can be used for mowing young grass, does not exceed 1.6 mm. I have on a similar trimmer how to remove the coil from the trimmer, and meanwhile the vegetable garden is overgrown. The thicker the thread, the more coarse grass it is able to overcome.

There are fishing lines with sharpened edges in the form of an asterisk or a square, this option is more adapted to mowing dry grass precisely due to the existing sharp edges, but its drawback is greater wear and is inferior in strength to a round cord.

Spiral line feed

The feeding of the line in a spiral when casting lures is one of the most common problems in the operation of spinning devices, which is solved in a rather simple way, because the problem of incorrect operation lies in the clogging of the line guide roller. The essence of repairing a spinning reel when this problem occurs is to clean the line laying mechanism from dirt.

You will need to disassemble the line guide roller, following the recommendations presented in our article in the previous chapters, and remove visible blockages with a brush, followed by washing the parts. Having lubricated the assembly again, it is sequentially assembled and the device is comfortably operated.

There are fishing lines with improved aerodynamics with corresponding dents, scales and notches, a similar product makes less noise, but it is used only on lawn mowers, since the exit of such a thread from the reel is difficult, it is used in most cases with discs into which segments are inserted. This video is about how to change the air filter on your Husqvarna trimmer (lawn mower). The disadvantage of such a product is its fragility.

Care and prevention of breakdowns

Maintenance and prevention of inertialess breakdowns are not at all difficult.

Important! The angler should consider as a rule mandatory pre-season maintenance of the device, as well as elementary surface cleaning and removal of moisture from the product after each end of fishing.

In addition, it is worth monitoring the careful transportation of the mechanism, avoiding bumps and falls. On the fishing trips themselves, you should not put rods with reels on the sand, and also try to lower the device into the water as little as possible. Attention and respect for the gear as a whole prolongs the operational potential of each element of the implement for a long time, including the spinning reel we have considered.

How to repair a spinning reel

A modern technological rod, whether it be a spinning rod or a float rod, must be completed with one of the types of reels. Most often, this element of equipment is an inertia-free, easy-to-use and affordable option in terms of price. By purchasing a mechanism, the angler expects the durability of the product to be used with the lowest maintenance costs. But one way or another, sometimes you have to deal with some malfunctions of the device, which in most cases can be repaired on your own without resorting to the services of professional craftsmen, thus saving both time and money, as a result, having confidence in the well-oiled operation of the mechanism.

To the attention of the reader, we will present a number of minor troubles that can happen to the inertialess during its operation, but such breakdowns are quite capable of fixing any fisherman who is in the slightest degree familiar with plumbing.

Step 4. measure the required amount of fishing line

Newbie mowers are usually interested in how many meters of line to wind on the trimmer reel? There are two ways to solve this issue:

  • Unwind a skein of line on a flat, dry place and separate half of it.
  • Measure 3-4 meters of line from the skein.

In any case, after the end of winding, the turns of the line should be on the body of the reel, without sliding off it. You don’t need to try to wind as much as possible, as the line will unwind poorly and break more often.

Step 5. winding the line onto the reel

How to attach the line to the trimmer depends on the coil design. Consider the option when the reel body has one outlet for the line. In this case, the end of the line is clamped in the crevice of the coil, and then we wind the line, trying to lay the turns as tightly as possible. The direction of laying the turns should be opposite to the direction of rotation of the coil and is usually indicated on its inner part. After the end of winding on the reel, you must put on a protective casing and bring the end of the line into it.

If the reel is designed to work with two tails, then the line must be folded in half and laid in the groove in the center of the reel. Further winding will be carried out along one or two slots, depending on the design of the coil. The direction of winding must also be opposite to the direction of rotation of the coil. At the end of the ponytail, the line will also need to be led out into the holes on the top of the reel.

DIY trimmer coil repair

The trimmer, whether petrol or electric, is the only solution for cutting grass in hard-to-reach places that a wheeled lawnmower cannot handle. As a cutting tool in trimmers, metal knives or special fishing line are used, which is tucked into the trimmer coil. But, unfortunately, trimmer heads become unusable over time during operation. Some malfunctions can be eliminated by hand, and some require a complete replacement of the mowing head.

Line does not extend automatically

If the line does not lengthen when you lightly hit the trimmer button on the ground, then the reasons for this may be the following.

Option 1. a bite has occurred, i.e. clamping the cord between turns. This problem usually occurs if the user has been winding the line on the reel unevenly, with intersecting turns, or winding it with insufficient tension. In the latter case, when the mowing head rotates at high speeds under the influence of centrifugal force, the cord begins to tighten, as a result of which inter-turn clamping of the fishing line is possible. To fix the problem, you will have to disassemble the coil on the trimmer and rewind the cord correctly, that is, in even turns with good tension.

Option 2. too short ends protrude from the head. The line may not come out when hitting the ground if the ends sticking out of the head are not long enough (short). In this case, the centrifugal force is not enough to stretch the line. Therefore, it is required to stop the unit (turn off the engine or disconnect the trimmer from the mains) and pull out the line manually, after pressing the button.

Option 3. the line is brazed inside the mowing head. This causes the coil to lock and not spin when the button is pressed. Basically, this happens for several reasons: poor cord quality, coil overheating during prolonged operation of the unit, line hitting hard objects.

  • In the first case, third-party cord can be made of low-quality and low-melting materials that cannot withstand mechanical and thermal stress. Therefore, you should give preference to “branded” lines.
  • But, if you nevertheless purchased a fishing line of unknown quality, and it is often soldered during operation, then you can follow the example of some users who, after filling the cord into the reel, wet it with either silicone grease (from a can) or mineral oil. This procedure greatly reduces the likelihood of the coils of the fishing line being soldered together.
  • Also, the line can be soldered if it hits a hard object (stone, fence, dry branch, etc.) during mowing. As a result, it stretches slightly and is pulled back into the head at high speed. From friction, the cord heats up, and its turns stick together. The only thing that can be done to eliminate this malfunction is to open the trimmer spool and rewind the line.

Major coil faults

Trimmer users and lawn mowers often face a problem with the semi-automatic mowing head. Coil malfunctions can be as follows:

  • the line does not lengthen automatically;
  • the cord spontaneously comes out of the reel.

How to remove the spool and replace the line

Trimmer owners, mostly beginners, find themselves in confusion, bordering on panic, when they need to change the cutting tool or line in the reel. Very often, when trying to unscrew the mowing head, users simply render it unusable, not suspecting that it is unscrewing in the opposite direction. To prevent this from happening, if you need to replace the tool, it is recommended that you read the step-by-step instructions below.

  • Stop the mowers engine or power off the trimmer before placing the line into the spool to avoid injury from accidental starting rotation of the cutting tool.
  • Unscrew the attachment attached to the gearbox shaft. To do this, the shaft must be fixed by aligning the holes on the washer and on the axle, and inserting a metal rod or screwdriver into them.
  • Unscrew the nozzle. You should be aware that the thread on the shaft is left-handed. Therefore, turn the trimmer coil to the right, that is, clockwise.
  • Disassemble the mowing head. Most often, the head cover is attached to the clips. To remove it, you will need to sink these latches into the case, squeezing the edges of the cover. If your trimmer has a semi-automatic mowing head with a button on the bottom, then the disassembly of the attachment should be done carefully, since you can lose the spring, which sometimes flies out when the cover is removed.
  • Cut off the required amount of line. Usually its length is 5 meters. Use a cord of the same diameter as indicated in the instructions for the tool. It is not recommended to exceed the maximum line diameter as this will result in increased engine load and higher gas mileage.
  • Find the midpoint of the line by folding it in half. You will have a loop.
  • Special grooves are cut inside the coil (there may be holes). Insert a loop of line into this groove.
  • Wind the line around the spool by turning it counterclockwise. It is necessary to fill in the cord as evenly as possible, the turns should lie down without overlap and with good tension. When the winding is finished, leave free ends of the line about 20 cm long and fix them in the grooves on the sides of the reel.
  • Assemble the mowing head. Be sure to insert the spring and washer (if equipped) before final assembly of the accessory. Place the spool in the body and thread the ends of the cord through the holes or lugs.
  • Put on the cover and secure it with the latches.
  • Screw the adapter back onto the gearbox shaft, also securing it with a screwdriver. You will need to twist the trimmer coil to the left (counter-clockwise).

The cord lengthens spontaneously

There are times when the trimmer user notices a very fast line flow. However, he never hit the ground with a button to lengthen the line. The reason for the fact that the line spontaneously lengthens, being cut on a special knife on the casing of the device, may be the absence of a spring in the mowing head. Often novice users of mowers, trying to load the line into the reel, forget to install the pressure spring in the head, or even lose it when opening the lid, and in the future, do not even suspect of its existence.

Also, the line can be lengthened without using the button if the spring is loose. If checking the spring has confirmed this fact, then several washers must be placed under it in order to enhance its clamping properties.

Trimmer coil device

Trimmer mowing heads come in a variety of designs, both simple and complex. The picture below shows an exploded view of the semi-automatic trimmer head from a Husqvarna (Husqvarna) lawn mower.

This type of head is found on most lawn mowers and trimmers such as Stihl (Stihl), Patriot (Patriot), Champion (Champion), Bosch (Bosch), Huter (Huter) and others. The device of the mowing head is quite simple. It includes the following details:

  • mowing head base;
  • button for semi-automatic cord feed;
  • bobbin (spool) into which the fishing line is tucked;
  • spring;
  • eyes. through them the line comes out;
  • trimmer head cover;
  • line (cord).

There are also simpler trim heads shown in the following photo.

All these attachments do not allow you to change the length of the line in a semi-automatic mode (after pressing a button). If the cord breaks, you have to stop the mower and change it manually.

Is it possible to make a coil for a trimmer with your own hands

  • Take a piece of plywood or PCB and draw a circle about 14 cm in diameter on it.
  • Cut the disc with a jigsaw or metal hacksaw.
  • Drill a hole in the center of the disc that matches the diameter of the gearbox shaft. Do not forget to put a washer on it before installing the disc on the shaft.
  • Small corners can be screwed along the edges of the disc or 1-2 holes can be made on opposite sides. They will serve for refueling the fishing line in them.
  • Several screws can be screwed into the plywood to fix the line.

This homemade mowing head is secured to the shaft with a nut. It will not work to tighten or unscrew the nut without fixing the shaft. To replace the cord, it will be enough to loosen the screws, insert a piece of line of the required length and press it again.

Also, the mowing attachment for attaching the fishing line to it can be made of metal sheet. How to do this can be understood from the following video.

To insert new nylon line into the trimmer, you will need approximately 3 meters of material in each groove (6 meters in total) of the dedicated plastic spool. The coil is preliminarily removed from the spindle together with the spring and washer. Remains of previously loaded nylon line from the spool must be removed.

Next, take a previously purchased nylon line (diameter 2.5 mm), unwind 6 meters of product, cut off a measured piece. Fold the resulting trimmer line in half. The end of the nylon line forms a kind of loop at the half fold.

Lawn trimmer (garden): how to remove the head replace the line install a brush cutter

A household tool, which is a lawn (garden) trimmer, is marked in practice by its active use. Technically, this type of machine is considered a very familiar device. Traditionally, brushcutters and string mowers have been based on a standard combustion engine system. True, electric models are increasingly appearing on the market. However, consider the first option in terms of maintenance.

Winding nylon line onto the spool of the head

At the next stage of the operation, grasp the coil of the lawn trimmer head with the palm of your left hand, holding it in the position as shown in the picture below. With your other hand, put a loop of nylon line over the protrusion of the central flange dividing the winding area of ​​the reel into two sectors.

Laying nylon line in the trimmer, more precisely in the sectors of the reel. Loop version of material stop before winding. Some lawn (garden) trimmers have other options for the stop (attachment)

Wind both halves of nylon line evenly and tightly counterclockwise (or in the direction of the arrow marked on the spool body). Stretching. it is necessary to wind the slings without twisting one slings on the other. Winding ends when the remaining ends of the nylon line are approximately 150 mm long.

Then insert the spool back into the spindle and pass the remaining 150 mm ends of the nylon line into the spindle grooves specially provided for this purpose. Next, the spindle part of the assembly is pressed into the palm of the left hand and on the opposite side of the coil, the washer and the spring previously removed are installed in place.

Assembly process. installation of the wound coil: 1. release the remaining 150 mm ends of the nylon line into special grooves of the spindle; 2. installation on the coil of previously removed elements

This completes the replacement of the fishing line in the trimmer, the assembled module is installed on the drive part, as discussed above in the text. Meanwhile, many models of lawn (garden) trimmers are also supplied with brush cutters, the use of which also requires installation procedures.

Assembling the head for a lawn hedge trimmer

Machines for processing lawns and other areas, along with impact heads, are supplied complete with brush cutters, which are actually circular metal saws. Brush cutters with 3, 8 or more cutting teeth are usually used.

To install a brush cutter for work, you will again need to remove the head of the scythe. Then the required tool for 3, 8 or more teeth is selected from the kit. Brush cutter discs are usually protected by a plastic guard in the blade area. The cover must be removed, after which the brush cutter disk is installed in place.

The sequence of installation of the brush cutter: 1. installation of the saw on the axle; 2. leveling washer; 3. circular cutter clamping cup; 4. lock nut; 5. clamping hex key

The installation does not require any special work. It is enough to put the selected saw, alignment washer and ring cup on the axle, and then screw and tighten the lock nut.

Tightening the nut requires securing the drive shaft (discussed above) and using a hex wrench (included), which is also used to replace the motor plug. Generally, the nut is tightened counterclockwise (on most models).

How to properly fuel the trimmer motor?

The automated garden scythe promises good durability when used correctly, including refueling. A gasoline engine of such a device is not allowed to operate on pure gasoline. Before refueling, you need to prepare a working mixture of fuel. namely, mix unleaded gasoline with engine oil.

The working fuel tank included in the kit, as a rule, has marks on the body for the correct mixture: 1. level of unleaded gasoline; 2. engine oil levels depending on the ratio

Mixing unleaded gasoline with engine oil is required in the correct ratio. Therefore, many manufacturers of string and other petrol trimmers mark working containers.

The user will only have to fill the mixing container with fresh unleaded gasoline in accordance with the fuel marker line. Then machine oil is added until the fuel mixture reaches the 40: 1 ratio mark (optimal for two-stroke engines).
