How to replace line on a trimmer?

Replacing the grass trimmer line with step-by-step instructions will allow even an inexperienced lawn mower owner to perform a rather difficult job.

However, before starting work on changing the line on the trimmer, it is necessary to ensure the safety of the work. In particular, measures should be taken to prevent unintentional or unintentional starting of the mower:

  • exclude spontaneous start,
  • remove battery (if applicable),
  • place the tool on a platform convenient for work.

It is convenient to replace the grass trimmer line when the mower is on the table, and the foreman, who replaces the grass trimmer line, has the ability to approach the tool from any side.

Step three: complete the head assembly

Pull out the ends of the line through a pair of oval spool slots. Replace both washers and spring (if any) with the supplied new parts. Bend both ends of the line at right angles.

The final technical touch of the process of changing the line on the trimmer is the imposition of the cap on the head, followed by fixation by means of pushing force and slight twisting.

Pass each end into the hole at the base of the winding drum. Install the coil in the inner area of ​​the head, resting on the spring. Put on the cover, align with the base and lightly push downwards with a small counterclockwise rotation, place the cover on the tabs of the clips. This completes the replacement procedure.

Removing the grass trimmer head cover

In the first step of disassembly, the grass trimmer head cover is removed. In the example of Black and Decker trimmer models and others, to remove the cover, it is usually enough to apply some pressure to depress the locking latch that is located on the side of the head body.

On some mower models, the grass trimmer head is initially removed using the Allen key supplied with the tool. The head is usually held in place by two to three screws, which are accessed through the side holes of the rear decorative cover.

The head cover, where the line spool is installed, is usually held by a latch-tongue. It is enough to squeeze the latch tab with some effort and turn the lid slightly, after which the lid can be easily removed

When releasing the locking tab, slightly turn and lift the cover of the grass trimmer head to remove the winding drum.

Installing a new line on the grass trimmer reel

Fitting a reel with a new line is carried out in the reverse order. The procedure looks something like the following, regardless of the lawn mower model:

Step one: securing and laying

Fold the end of the line in half. Place a blank over the spool on each side of each half of the winding zone. Wrap both halves completely around the winding drum. Pull the line through the loop.

The procedure for preparing the line engagement in the area of ​​both winding sections of the drum. The loops are placed in specially made cutouts, after which the line is wound in each zone

It is enough to pull the line tightly and plant the knot in the groove made on each side of the winding drum.

Step two: winding the cutting material in sections

The next step is to wrap the line around the reel, being careful. It is necessary that each half is filled with its own winding, evenly, without intersections. Usually, arrows can be seen on the body of the winding reel, indicating the direction of winding. This point should be borne in mind when filling the spool with fishing line.

Features of the use of trimmers

Such a convenient, and most importantly, effective device, like a grass trimmer, exists in several variations:

  • petrol;
  • rechargeable;
  • electric.

As the names suggest, the types of grass trimmer are noticeably different from one another. But regardless of the type of this tool, a fishing line can be its cutting element. Of course, the line tucked into the reel of the grass trimmer is not endless. And sooner or later you will need to replace it with a new one.

Line consumption directly depends on the frequency of use of the device and the scale of the work performed. The more grass is cut and the more often it is trimmed with the grass trimmer, the more active the line is. And, accordingly, the faster it will end. In this regard, the question arises: how to tuck the line into the reel of the grass trimmer?

Not everyone knows the answer to this question. But winding the line on a reel plays an important role in the operation of the grass trimmer.

For the device to function properly, it is very important to properly wind the new line onto the reel. How to change the line on the trimmer, and will be discussed in this article

Thickness selection

In addition, you should pay special attention to the thickness of the consumable. For mowing young grass, a thread with a diameter of one and a half millimeters is suitable.

The larger the diameter of the thread, the drier and coarser weeds it is capable of overpowering.

When choosing a fishing line by thickness, there is one “but”

It is important not only to assess the capabilities of the material, but also to take into account the features of the grass trimmer. Be sure to check the user manual that came with your tool for information on cutting element requirements.

Using the wrong thread can damage the tool. Using a thread that is too thick will overload the machine’s motor. And the use of a thread that is too thin will significantly increase the wear of the twisting mechanism.

That is why the choice of consumables must be approached no less responsibly than filling it into the grass trimmer. When a suitable fishing line is found and purchased, you can begin to consider ways of winding it on a reel.

How to choose a line for your grass trimmer

The consumption of the line for the grass trimmer when using a faceted and reinforced consumable will decrease by 2-3 times, the performance will increase by the same amount compared to a round line and a line that is not reinforced with fiberglass.

Purchase the material with a diameter not less than that recommended by the manufacturer. If the diameter is unknown, you need to look at the size of the holes on the outer casing of the mowing head: the diameter of the working thread should be slightly smaller than the hole in order to freely pass through it.

Having found out how much material is needed for one winding, be guided by the length of the scaffold with the next purchases, so that there are no pieces that are too short for winding.

To replace the forest on a mechanical scythe with your own hands, you need to disassemble the mowing head and get the spool on which the working thread is wound.

What is needed to replace the cord

With regular use of the grass trimmer to cut grass, the discs become dull, but they can be sharpened and continued to operate. The fishing line in the reel tends to end, so it becomes necessary to refuel a new one, for which it is necessary to determine the type of head and prepare the cord of the required thickness and length.

So, the mowing head is a cylindrical body in which a bobbin with a fishing line is placed. Such a detail is present both on electric trimmers and on gasoline scythes of any brands, be it Bosch, Makita, STIHL or another brand. There are three types of heads depending on the method of threading and feeding the line.

The principle of operation of the heads of the automatic group is that they independently feed the line when the mower reduces the engine speed. Such designs are convenient when working on large areas, but have a drawback. a large consumption of cord. Semi-automatic group heads are easy to operate. automatic line feed is performed at maximum engine speed

To release the lanyard blockage, gently tap the tool on the ground and the unlocked thread is pulled out of the spool. Cutting to the required length is made with a knife attached to the protective cover. grass trimmers with manual line feed must first be switched off, then pull out the line yourself.

Reels for electric and gasoline braids can be with one or two line tendrils. The former are used for trimming low grass growth, the latter for mowing tall grass and small shrubs.

Preparation for winding the line

Before the winding process, it is necessary to remove the spool with line from the body. Depending on the manufacturer, power and type (electric or gasoline), there are three design types of trimmers:

This type of tool has a lower position of the motor and head, which in turn has two side buttons for removing the bobbin. When pressed at the same time, the upper part of the reel with the line is disconnected, and the lower part remains rigidly attached to the braid. Experts recommend disassembling on a level platform in order to prevent the spring from jumping out.

Powerful petrol trimmers and straight boom electric trimmers.

This model provides the ability to install a knife. Removing the coil in such models is done by means of two keys recessed into the coil body. To mount the trimmer knife, it is necessary to align the hole of the reel and the rod, and then insert the device in the form of a steel pin (screwdriver, iron bar). After fixing the coil, the body can be easily unscrewed by hand in a clockwise direction.

Tips and tricks on how to wind the line and what you need to know

There are some useful tips and tricks that will be useful to learn not only for beginners, but also for experienced mowers. These tips will help prevent negative consequences in the form of injury and malfunctioning of the mechanism. These guidelines read as follows:

  • It is necessary to install the cover until it clicks. over, this is 2 or more clicks, depending on the number of latches. If one of the latch does not snap into place, the drum may jump out when starting the tool and injure a person.
  • Do not reel in the line with a strong pull, or more than you can insert it into place. It is better not to wind up the rig than there will be more of it, as this will lead to negative consequences in the form of the impossibility of unwinding it if necessary
  • If you own a tool not with two line leads, but with one (usually these are low-power units), then the winding process is carried out in the same sequence as described above, only with the difference in the absence of a middle edge between the extreme bases of the coil
  • After replacing the material, it is necessary to first check the operability of the tool, and after that start mowing the grass. If you do not make a preliminary check, then the scaffolding can unwind and injure a person.

It is interesting! Choose material of appropriate quality to avoid injury when working with petrol cutters, trimmers and brushcutters. In the process of mowing the grass, small stones and other materials fall under the rotating parts, which can fly off over long distances, therefore, despite the fact that the fishing line is not a knife, work with the tool should be carried out in protective special uniforms.

The result of the work done is as follows. after the replacement of the new material, the usual one is enough for an area of ​​up to 600 square meters, but taking into account the presence of a reinforcing layer on the fishing line

Conventional nylon materials last less, which is important to consider when working. Do not try to mow thick-stemmed grass with fishing line, as there are special metal discs or knives for this.

How to wind the line on the reel of a grass trimmer: winding methods and videos

Any garden owner knows how quickly weeds can fill an area. A grass trimmer will help you to defeat them without undue effort. This incredibly useful device is an indispensable tool for trimming and mowing grass.

It is no secret that an ordinary lawn mower cannot be used everywhere. In contrast, the trimmer can handle even very difficult areas. This is especially true for those tools in which not a knife, but a fishing line acts as a cutting element.

Which line to choose

Before you stock up on this material for dressing in a grass trimmer, you need to decide on the choice. After all, the usual so-called round fishing line is far from the only existing species. How to choose the most suitable one? First you need to determine the working conditions.

Selection by type. Round line is the most common. It will fit any coil with rare exceptions. This type of consumable is suitable for cutting fresh, juicy grass. But with the mowing of the so-called dead wood, such a species may no longer cope. It is pointless to mention attempts to mow bushes with this thread.

In addition to the usual type, there are others that have sharp edges. Usually they are made with an asterisk or a square. The presence of sharp edges is the main feature and key difference between these threads.

It is thanks to this feature that the threads of these types are able to mow dry weeds. But sharp-cut threads are not without drawbacks, the main of which are quick wear and strength, which is noticeably inferior to the round type.

In addition to the already mentioned types of woods, there are also interesting and common varieties. Especially among them can be noted fishing lines, inside which a metal wire is stretched. This type of thread is often used in gasoline powered tools with an engine over 1.5 horsepower.

Metal-cored threads come in both round sections and sharp edges. Regardless of the type of section, such threads are the best suited for overcoming difficult-to-cut plants. Threads of this type can easily mow not only dry grass, but even small bushes.

The wires with a wire inside compare favorably with other types of consumables for their incredible wear resistance. Unfortunately, this feature has a more than noticeable impact on the price of this type. The cost of yarns with a core is much higher than the cost of other types of yarns.

The first way to wind the line

The required amount of line has been cut off. Now you need to carefully examine the bobbin in order to understand what type it belongs to. It depends on how the line is to be wound on it.

There are two types of bobbins. In general, they differ slightly from each other. Regardless of the type, the coil is divided into two sections. upper and lower. In the first type, the dividing edge does not close into a ring and has a depression.

In the second type, it is solid, but near it there are small through holes on the sides on both sides. The method of winding the thread must be studied depending on which of the above types the coil belongs to.

  • The previously prepared six-meter segment must be bent in half. It is best not exactly in the middle, but in such a way that one half is about fifteen centimeters longer.
  • Then the place of the fold must be inserted into the recess in the dividing face. One half of the line should be at the top of the reel, the other half at the bottom.
  • Now you can start winding directly. You need to wind in the direction of the arrow on the bobbin. When winding, you need to keep the threads so that they do not intertwine and the upper half winds up in the upper part of the spool, and the lower half in the lower part. Each half should have about fifteen centimeters free from the end.
  • There are small indentations (or, in other words, grooves) in the upper edge of the bobbin to secure the consumable. The ends of the threads must be inserted into these grooves so that they are fixed against each other.
  • The final step of loading the consumables into the tool is to thread the ends attached to the bobbin into the corresponding holes in the grass trimmer head.
  • That’s all. The winding process is complete. Now all that remains is to assemble the head into a single whole. The spring fits neatly back between the bobbin and the head. Then you need to insert the bobbin into the head and press them together.
  • It is recommended that the free ends of the thread be pulled out more. To do this, pull the ends of the consumable one by one so that they are removed from the grooves of the bobbin. You can make sure that the cutting element is removed from the retaining grooves by trying to pull the threads a little. they should freely exit through the holes in the head.
  • While pressing the bobbin down, you need to put the cover over it. The cover must be screwed to the head so that all the grooves on their bodies are aligned and the bobbin remains fixed between them.
  • And finally, the very last action. the head is screwed back into place at the bottom of the tool.

The process is complete. The line is tucked into a reel. grass trimmer ready for further work.

Thickness selection

In addition, you should pay special attention to the thickness of the consumable. For mowing young grass, a thread with a diameter of one and a half millimeters is suitable. The larger the diameter of the thread, the drier and coarser weeds it is capable of overpowering.

When choosing a fishing line by thickness, there is one “but”. It is important not only to assess the capabilities of the material, but also to take into account the features of the grass trimmer. Be sure to check the user manual that came with your tool for information on cutting element requirements.

Using the wrong thread can damage the tool. Using a thread that is too thick will overload the machine’s motor. And the use of a thread that is too thin will significantly increase the wear of the twisting mechanism.

That is why the choice of consumables must be approached no less responsibly than filling it into the grass trimmer. When a suitable fishing line is found and purchased, you can begin to consider ways of winding it on a reel.

How to wind the line onto the spool of the grass trimmer

At first glance, threading a line into the reel of a tool is not an easy task. But it is enough to carefully study this process. and in the future, all the necessary actions will be performed without any difficulties.

Read this guide to learn how to line your grass trimmer. The step-by-step instructions below take into account the peculiarities of the spools of different types of trimmers, therefore, it is applicable to any tool.

  • The line spool is the bottom edge of the grass trimmer. First of all, of course, you need to remove this head from the device. To do this, you need to fix the rod (or, in other words, the shaft) on which the coil is attached. It is required to fix it in such a way that it does not scroll. The easiest way to do this is by placing a kind of stupor (preferably metal) between the shaft threads through a special hole. When the shaft is fixed, the spool can be unscrewed.
  • At this stage, you have to remove the bobbin from the head, on which the fishing line is attached. To do this, you need to disassemble the head into elements. To do this, you first need to find a retainer on its body. It is located on the circumference of the product and is like a button. When the latch is found, you need to press it firmly. Keeping the latch pressed, turn the head cover clockwise. Then you need to remove the cover and remove the bobbin.
  • A tight spring is placed between the bobbin and the head. It needs to be put aside for a while so that it does not interfere with the winding process. Before proceeding with the step of winding the line, it is necessary to inspect the bobbin. If there are remnants of old fishing line on it, they must be removed. When the bobbin is cleaned, you can start preparing a new bobbin.
  • From a previously prepared skein of new fishing line, it is necessary to measure and cut off six (maximum. seven) meters. Keep the bobbin close at hand.

At this point, the key stage actually begins, which this article is devoted to.

Features of the use of trimmers

a grass trimmer that mows grass with a fishing line can be used near: houses and other buildings, fences and hedges, trees and shrubs, flower beds and flower beds, row spacing in a garden plot.

Such a convenient, and most importantly, effective device, like a grass trimmer, exists in several variations:

  • petrol;
  • rechargeable;
  • electric.

As the names suggest, the types of grass trimmer are noticeably different from one another. But regardless of the type of this tool, a fishing line can be its cutting element. Of course, the line tucked into the reel of the grass trimmer is not endless. And sooner or later you will need to replace it with a new one.

Line consumption directly depends on the frequency of use of the device and the scale of the work performed. The more grass is cut and the more often it is trimmed with the grass trimmer, the more active the line is. And, accordingly, the faster it will end. In this regard, the question arises: how to tuck the line into the reel of the grass trimmer?

Not everyone knows the answer to this question. But winding the line on a reel plays an important role in the operation of the grass trimmer. For the device to function properly, it is very important to properly wind the new line onto the reel. How to change the line on the trimmer, and will be discussed in this article.

Second winding method

  • A previously prepared six-meter-long segment is required to be bent exactly in the middle and cut. Thus, two segments of the same length are obtained.
  • At one end of each segment, you need to make a small “hook”. To do this, it is necessary to bend a couple of centimeters from the edge and fix it for a short time so that the “hook” does not unbend.
  • Then one segment is taken. The hook is inserted into the through hole at the top of the bobbin.
  • Now you can proceed to the key stage. winding. The direction in which to wind is indicated by an arrow on the bobbin. It is important to make sure that the line is wound strictly within the upper part of the reel. You do not need to wind the thread to the very tip. about fifteen centimeters should remain free from the end.
  • In the upper edge of the spool there are small recesses (so-called grooves) for fixing the consumable. The loose “tail” of the thread must be inserted into one of these grooves.
  • The top of the coil is tucked in. Now you need to do the same procedure with the bottom. Take the second piece of thread. The “hook” is threaded through the through hole at the bottom of the bobbin.
  • After that, you can start winding the fishing line (within the lower compartment). And for this segment, you also need to leave about fifteen centimeters free from the end. This remaining “tail” must be inserted into the notch opposite to the one into which the end of the first segment was inserted.

The subsequent steps for this type of coils are exactly the same as described for the previous type in paragraphs five to nine.

This is how the line in the grass trimmer spool changes. There is nothing complicated in the process. And already after several refuelings, all actions will come to automatism.

To visually study the process described above, you can turn to the Internet for help. On the popular YouTube portal there are many different videos showing how to wind the line on the reel of the grass trimmer.

Automatic (non-separable)

Here are the steps to follow:

  • press the shock button and remove the rest of the line from the head;
  • move the button to the position of changing the string, for which align the marks on it and the top cover;
  • cut a piece of string 2-3 m long, insert this piece into the spool;
  • wind the string by turning the button, the direction of rotation is indicated on the body.

Collapsible spider

Here are the steps you need to follow to change the line:

  • lock the grass trimmer gearbox to prevent rotation of the head;
  • loosen the bolt that holds the line by turning it counterclockwise with the hex key;
  • pull out the remnants of the string;
  • cut 2 pieces of new fishing line of the required diameter, the length of each piece is 20–40 cm;
  • insert both segments into the holes of the coil so that they are halved by it;
  • tighten the fixing bolt.

Semi-automatic (collapsible)

Despite the variety of models and differences in appearance, coils of this type are arranged and work according to the same principle.

  • basics;
  • spools;
  • clamping spring;
  • detachable body with string holes.

The base connects the remaining elements of the trimmer head with a brushcutter or electric scythe through a threaded bushing melted into it, so each coil fits only that trimmer, the diameter of the gearbox shaft or the lower motor corresponds to the diameter of the bushing.

A spring is installed inside the base, which supports the spool, squeezing the pressure part outward through the removable body.

On the spool and body there are locks that prevent the first from turning, however, when the operator hits the ground with the pressure part, the spool disengages from the locks of the removable body and rotates freely.

Holes for the string are made in the removable body, and they are located so that the line exit from the spool is noticeably higher, this ensures reliable fixation of the fishing line in working order.

When the operator hits the ground with the pressure part, the spool enters the body and all the holes through which the line passes are aligned. Then centrifugal force pulls part of the wound string outward, and when the pressure on the pressure part disappears, the spool comes out of the body and returns to its working position.

Semi-automatic (collapsible)

Here are the steps you need to follow to change the line:

  • squeeze the clips to separate the top from the base;
  • remove the upper part and pull out the spool without losing the spring;
  • remove the remnants of the old fishing line;
  • cut a piece of string 2-3 m long;
  • fold the segment in half;
  • insert the curved middle of the segment into the slot of the bobbin;
  • wind the string according to the direction signs on the spool or top cap;
  • fix the line on both sides in the slots of the spool;
  • insert the spool and spring into the base, passing both ends of the string through the corresponding holes;
  • replace and fix the top cover;
  • Pull on each end of the line alternately to release the string from the catches.

Automatic (non-separable)

Regardless of the model and manufacturer, all automatic reels are designed and work according to the same principle.

They consist of the following parts:

  • basics;
  • spools;
  • cap;
  • clamping spring;
  • detachable body with string holes.

A threaded sleeve is soldered into the body of the base, and ratchet clamps are installed on the inner surface, which allows the spool to rotate in only one direction. Inside the spool there is a through channel for the line wire. The cap is firmly put on the spool, and the curly edges make it easier to rotate for winding the fishing line.

How to wind the line correctly?

The winding method depends on the type of spool, but in any case, you must first select the correct cutting material. The diameter and shape of the fishing line is indicated on the packaging or in the instructions for each model, it is very important to use just such a material, otherwise there will be problems with winding.

Mechanical

A mechanical reel is a plastic or metal disc in which one or more small pieces of line are fixed in various ways, which is why you have to constantly change the line manually on it.

Here are the most popular models of such heads:

Spider and Wind

Here’s how to properly wind the line around the mower’s reel:

  • grab the line running along the inside of the reel with your fingers and pull it out of the head;
  • cut a new string into pieces of the desired length;
  • insert the piece into the hole a little more than half the length, then wrap it and bring it out through the adjacent hole;
  • if the fishing line is thick, then you can make pieces of shorter length and, after inserting into the spool, wrap the edge of the string so that it enters the adjacent hole by 0.5-1 cm.

How to wind the line around the mowing head of a grass trimmer or brushcutter

The video shows in detail how to wind the line onto the spool of a grass trimmer or brushcutter. Refueling with mowing line.

How to remove the spool from the grass trimmer and remove the line

Initially, remove the line from the spool of the grass trimmer before threading it into the spool. A reel or aiming device is a device that sits inside the mowing head, bobbin or drum. There are different types of heads (depending on the manufacturer), but the principle of replacing the line on the reel is the same for everyone. First of all, we will figure out how to remove the head from the tool, as well as how to get the drum and fishing line out of it.

It is interesting! The tooling can be changed directly on the tool, but if you are doing this for the first time, it is still recommended to remove the head and study the detailed winding process. After the technology has been mastered, you can perform replacement work on a trimmer, a brushcutter or a petrol cutter.

The instruction on how to unscrew the manual head on the trimmer is as follows:

  • Turn the tool upside down and, if necessary, clean it from dirt. With two fingers of one hand, grip the cover latches (on the mowing head), which are symmetrically positioned to each other. After lightly pressing them inward, remove the protective cover from the drum
  • Next, remove the line spool from the drum shaft. It is mounted on a shaft without fasteners, therefore it can be removed with one hand.
  • The main part of the drum is fixed with a screw, which must be unscrewed with a screwdriver with an appropriate tip or bit
  • To unscrew, hold the drum base with one hand, and unscrew it counterclockwise with a screwdriver with the other.
  • After that, you can proceed to dismantling. To do this, you do not need to pull it with all your strength, but slightly shaking it to the sides, slowly disengage it from the metal shaft on which the drum is seated.
  • When reinstalling, fit the head into the square slots

This process is not difficult, and as you know, there is no need to dismantle the entire head if you know how the replacement is performed. When dismantling, consider the following nuances:

Knowing how to disassemble the drum, you should continue to figure out how to change the grass trimmer line. The video below shows the detailed process of how to open the grass trimmer coil and disassemble it.

Removing the coil from the grass trimmer

On small electric bottom motor trimmers (when operating near the ground), the reel usually has two buttons on the sides. Click on them and disconnect one half of the coil body from the second, which remains on the trimmer. Together with the first half, the inner part is also taken out, on which the fishing line is directly wound. When parsing, be careful: there is a spring inside that can fly out and get lost.

On electric and gasoline trimmers with a curved bar (there is still no way to put a knife on such trimmers), you need to wrap the coil body itself with one hand, and with the other hand you need to start rotating the lamb on it counterclockwise. It is he who attaches the coil to the grass trimmer bar. Having unscrewed the lamb, carefully remove the entire coil, trying not to lose the spring inside.

On electric and gasoline trimmers with a straight bar and a gear at its end (on such grass trimmers, in addition to fishing line, you can also install a knife), we look for a hole under the coil, insert, for example, a screwdriver into it, quietly rotate the coil until the screwdriver crawls even deeper and the coil will lock. Now turn the whole coil clockwise (since the thread is left-hand) and remove it from the grass trimmer. Next, we disassemble the coil. It can be assembled with latches or twisted with a lamb. If the coil is on latches, then press on the sides on the base of the latches so that they bend and release one half of the coil body from the other. We just unscrew the lamb. There may also be a third type of connection of two halves of such a coil: with it, you need to grab the lower part with one hand, and the upper part with the other, and start turning them in opposite directions. When disassembling such a coil, you also need to make sure that the spring inside is not lost.

A few tips for properly stringing your grass trimmer

Grass trimmer head with automatic line threading

Some models on the market have a reel with an automatic winding mechanism. It is enough for the owner to properly thread and fix the ends in the head, and the winding operation will be performed by the tool itself when it is turned on. It is almost impossible to wind the line incorrectly in a grass trimmer with such a head, since the coil independently determines the position of the antennae. The advantages of the automatic grass trimmer head include ease of threading the line, and the disadvantages are frequent breakdowns of the mechanism due to the complexity of the design and high cost.

Single-barb grass trimmer reel

Many owners and specialists note the ease of use and ease of refueling the bobbin with one mustache. Depending on the manufacturer, the length of the threaded line can vary from 2 to 5 meters. The end of the line is inserted into the head into a special technological groove or hole, and the winding is carried out in the direction opposite to the working rotation of the bobbin. Most reels have arrow marks on the outside of the body that indicate the direction of travel of the grass trimmer reel.

After winding, you need to leave a free end of 15-30 cm to enhance the centrifugal force, which is decisive when removing the trimmer line in automatic and semi-automatic spools. We pass the left end through the working hole of the coil and assemble the head.

How does the head with a fishing line work on a brushcutter why you need to know the principle of operation

Depending on the manufacturer, the heads differ structurally not only externally, but also internally. Most drums have a pressure spring inside (semi-automatic and automatic). Above is an instruction on how to disassemble the grass trimmer head without a spring, i.e. on the head of the manual type. The principle of dismantling a semi-automatic head with a spring inside is almost identical to the instructions described above.

The principle of operation of the semi-automatic grass trimmer coil is as follows:

  • Inside the head there is a coil, which is fitted on the slots, which prevent its free movement.
  • A spring acts on the coil, which presses it against the splines in the cover structure
  • A fishing line is wound on the tip, the length of which depends on the tool itself. Typically this length is between 1 and 4 meters.
  • During the performance of work, if it is necessary to increase the length of the line, the protruding part of the drum is pressed, whereby it disengages from the splines. In this case, the fishing line is unwound from the drum, increasing in length
  • After releasing the required amount of fishing line, release the pressure and continue cutting the grass

The advantage of a tool with a line is that this consumable does not require sharpening, compared to metal discs. In addition, if a stone or a tree comes across on the way, the line simply breaks off, without adversely affecting the gearbox and engine of the tool, as is the case with metal cutting discs.

Knowing the design and device of the types of mowing or trimmer heads, it is necessary to go on to consider the process of threading the line into the grass trimmer reel. After all, it is this very moment that causes difficulties for most owners of special tools.

On most electric and petrol trims, you will need to remove the spool to replace the line. The FUBAG tool (electric and petrol trimmers) allows you to skip this step. To make the instruction universal, we will still consider it in detail:

Secure the shaft. Insert the locking element into the corresponding hole. It can be a thin screwdriver or a metal rod.

Unscrew the bobbin case. In our example, strictly clockwise.

Unscrew the cover according to the direction indicated on the body.

The preparatory stage has been passed. You can proceed to winding the fishing line.

How to choose a fishing line. length, diameter, restrictions

IMPORTANT TO REMEMBER! Do not use fishing line or metal cables for the grass trimmer. This replacement is ineffective and dangerous. The rope can injure not only the mower himself, but also those around him.

In terms of length, you should rely on the estimated frequency of use of the grass trimmer. The more often, the more it costs to stock up expenses.

Information about the possible line diameter can be found on the body grass trimmer spools. Most likely, the range will be indicated there. The thickness varies from 1.2 to 4 mm. Choose the appropriate option, taking into account the characteristics of the cultivated area. The larger the diameter, the easier it is to mow tough grass.

Winding Algorithm

Lay the line in the direction indicated on the element body.

Insert the short end into the slot on the side of the spool.

Secure the long end in the opposite groove.

Place the spool of coiled line into the spool body.

Trim the ends of the line, leaving 10 to 15 centimeters.

The line change is complete and now all that remains is to screw the bobbin onto the grass trimmer and you can work.
