How to unscrew a spool of fishing line on a trimmer

Preparing for replacement

For clarity, the mowing head (spool) was removed from the brush cutter. There is no need to remove the fishing line to replace it; everything is done locally. It doesn't take much time.

We disassemble the trimmer spool - it is held on by latches. Remove the cover by pressing the latches. If there is not enough effort to do this with your hands, then use a screwdriver.

The spool consists of the following:

Housing with spring
Cover with locking latches
Reel with button

The operating principle is as follows. By pressing the button, the reel presses on the spring and comes out of the fixing grooves in the spool cover. By holding the reel in this state, you can twist it, thereby adjusting the length of the fishing line. When the button is released, the housing spring returns the coil to its original fixed state.

There are several holes on the bottom of the reel for different diameters of lines. These may differ between trimmer manufacturers. In some cases (like here) they are signed, in others they are not.

These holes are needed to fix the fishing line when replacing it. After winding the fishing line around the bobbin, the ends of the latter are inserted into them. This is necessary so that the line does not unwind when the reel is installed in the trimmer body. In other words, it makes line changes easier.

There are models without indicating the diameter of the consumables. Then, in order to find out what maximum diameter of the line can be used, it is tried on using the holes for the line exit from the trimmer spool body (see the figure below).

The reel has two sections for fishing line, separated by a partition. They may not exist. They are needed only to differentiate and facilitate winding of consumables.

First, the required length of the loess is determined. The latter is wound into one of the sections of the coil so that it does not extend beyond its limits. In this case, 3 mm was wound, the length turned out to be about 2 meters. Those. for two sections you will need a 4 meter piece - this is for the 1st method. For the second method, you need two pieces of 2 meters each.

Now you need to figure out which way you need to wind it. To do this, many manufacturers of trimmers put special markings on the reels, such as in the figure below.

If no such markings were found, then you need to pay attention to the spool body. There must be an arrow there that indicates the movement of the mowing head. The line is wound in the opposite direction.

Scaffold winding algorithm

Depending on the trimmer model used, the type, thickness and length of the mowing line are selected. The diameter of the cord can be from 1.2 to 4 mm. It is not difficult to guess that the thicker you thread the cord, the tighter and thicker it can be cut.

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

Refer to the device manual for cord thickness information.
Look at the coil itself. It may be marked with information about the possible diameters of the mowing line.
Insert the line into the socket. If it fits easily, you can use a cord of that diameter.

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

First way

To correctly determine how many meters of fishing line are needed for a particular reel, it is necessary to wind it onto the reel so that the reel does not exceed the diameter of the boards. If the line extends beyond the edges of the spool, you cannot insert it into the cap. Once you have decided on the length of the material, you need to load it into the spool, so do the following.

You need to fold the fishing line in half, so that one end is 10-15 cm longer than the other.
Please note that the coil is divided into 2 parts by the central side, from which charging begins. Find the recess on it and insert the cord, bent in half, into it with a little force.
It is very important to determine in which direction the line is wound to the reel. If you look closely, you may find an arrow on the reel or a label with an arrow indicating which direction to wind. There are cases when there is no arrow on the reel. In this situation, you can look at the painted arrow on the mower head and wind the cord in the opposite direction.
Winding should be done carefully, wrap the spool with maximum thread tension.
Once the cord is finished, you must first secure the short end of the mowing line by inserting it into a slot of the appropriate diameter on the side of the reel.
The other end, the genuine one, is installed in a groove on the opposite side of the coil.
After securing the mowing line, cut off its ends, leaving an allowance of about 10 cm.
Next, you need to install the aged reel into the mowing head. To do this, insert and pull the threads into the outlet holes of the head, insert the reel into the body, and then, applying the necessary force, pull the line out of the mounting grooves and tighten it.
You can now put the cover on and secure it with the latches.

Replacing fishing line in a trimmer: 2 simple ways

A trimmer is a necessary and useful tool for a summer cottage and a private home. Many people own and actively use it, but not everyone knows how to replace the line in a trimmer , especially at first.

In this instruction we will walk you through the entire replacement process step by step. Looking ahead, there are two ways to thread a trimmer spool with line. There is no fundamental difference - the difference is that in the first case there will be one fishing line folded in half, and in the second there will be two sections of such fishing line.

What can be used instead of fishing line

Many trimmer users are interested in the question: what can replace the default cord used in such a device? They begin to carry out dangerous experiments by installing metal or copper wire, metal cables or strings, and ordinary fishing line in the mowing head.

If a metal cable is installed instead of a fishing line, then the trimmer becomes a dangerous device not only for the user, but also for others. This fact is explained by the fact that during operation of the unit, the steel cable will gradually work, its ends will be unraveled, and small pieces of wire will fly in different directions at high speed.

And if you accidentally touch your or someone else's foot while working with a steel cable (wire), this will cause a strong and deep cut in the tissue, and in some cases, amputation of the toes. It is not surprising that the manufacturer uses nylon for this purpose, since it is quite light and strong, and when disconnected it does not fly out and cannot cause injury.

Using a line in a trimmer instead of a standard one is of course possible, but it will cause you additional hassle because it wears out quickly, breaks, cuts slowly and is not suitable for cutting hard grass. In addition, a lot of time is wasted during work to replace a broken tool more than once.

In practice, installing a regular fishing line is justified if the user is going to mow the grass near the fence, especially if it is made of mesh. In this case, to protect the standard and sometimes expensive cord from wear and tear, it is replaced with a line that is not AL-KO. Usually, to replace the fishing line cord, you need to choose the thickest one. 2-3 mm.

How to remove or thread line into a trimmer

It will take about 10-15 minutes to wind the line. What is coil ? A plastic case with a cassette inside, on which there is a special hook for convenient winding of fishing line.

Almost all trimmer reels have a similar fastening principle; this is a central screw-button, when pressed, it becomes possible to pull out the fishing line to the required length. The photo below shows some examples of different trimmer reels.

The reels of trimmers, the motor of which is located close to the ground, have a different attachment to the axis of rotation; they have two buttons on the reel located on the sides that need to be pressed out; otherwise, replacing the thread is no different from other cassettes.

The principle of correct winding of fishing line is similar in all of the above cases, so for example, consider the standard version with two tendrils.

To remove the spool of fishing line, you need to unscrew the screw located in the center, but keep in mind that the thread there is left-handed, so you will have to turn it clockwise, this was done on purpose so that during operation it does not open under the influence of centrifugal force.

Next, using a screwdriver, disassemble the head and remove the reel on which the fishing line .

Having measured the required length and folded it in half, you need to thread the fishing line into the reel, eventually bringing its ends opposite each other (for this there are special slots for fixing).

After this, you need to assemble the head in the reverse order, threading the ends of the cord into the two corresponding holes.

If you have any doubts or it is not entirely clear how to load the fishing line onto the trimmer, we recommend that you look at how to properly wind the fishing line into the trimmer.

In this video, step by step, the instructor will open the trimmer head, measure the required amount of fishing line, usually from two to four meters, and demonstrate assembly and installation on the trimmer.

Video: Replacing the Coil on an Electric Trimmer

Second way

Some reels provide a second way to secure the cord: instead of one folded in half, you can load 2 pieces of thread. . the fishing line is replaced in accordance with the following algorithm.

Before replacing or loading new filament into the spool, determine how many meters you will need as described above.
Bend one end of the cord into a hook.
Find the hole at the bottom of the spool to secure the line and insert the bent end of the thread into a 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 reel.
Do the same for the second coil socket.
Assembling the head is no different from the method that was envisaged when threading the reel, considered with a double piece of fishing line.

For Stihl brand motor braids there is a very simple and quick way to change the line without disassembling the mower, which you can see by watching this video.

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

Turning on the trimmer (during rotation, the ends of the fishing line will be trimmed around the knife attached to the protective cover for this purpose);
Trimming the excess ends with scissors so that they do not touch the body.

READ How to Disassemble a Lawn Mower Reel

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 threaded onto the mowing head, but the protruding ends of the cord are not long enough, they must be lengthened before starting the machine. This applies to a manually adjustable head . However, there are times when using a semi-automatic mower when, due to the insufficient length of the protruding ends of the cord, they do not automatically extend. In this case, you must turn off the unit (it is absolutely necessary to remove the plug from the socket on the electrical device), manually press the button located at the bottom of the part, and pull out a little fishing line. After this procedure, the cord will be able to lengthen again due to centrifugal force if you set the spindle speed to maximum.

What types of fishing lines are there?

The most common type of fishing line, which is suitable for almost all types of reels, is round cord. This is an ordinary fishing line , suitable for mowing succulent grass, but it will be much more difficult to mow dead wood, and even more so it will not cope with bushes.

As a rule, the diameter with which young grass can be mowed does not exceed 1.6 mm. The thicker the thread, the coarser the grass it can overcome.

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

There are fishing lines with improved aerodynamics with characteristic dents, scales and notches; such a product makes less noise, but it is used only on lawn mowers, since it is difficult for such thread to come out of the spool; it is most often used with disks into which segments are inserted. The disadvantage of this product is its fragility.

Most often in gasoline trimmers with an engine power of more than 1.5 hp. cords with a metal cable inside are used.

READ How to Thread Line into the Reel of a Champion Trimmer

This thread is ideal for mowing dry grass and small shrubs. The presence of a core has a positive effect on the wear resistance of this material.

The disadvantage of such a cord is its price, which is significantly higher than the above listed opponents.

When to use a disc rather than a line

For owners of country houses, land plots, and lawn lovers, a trimmer is an assistant that speeds up routine work. When using a tool, a number of questions arise related to which attachments are preferable to use and how to replace them yourself.

When working with a lawn mower, fishing line is often used, which is cheaper than discs. In addition to price, it also has the following practical advantages:

can be used with a large number of trimmer heads;
fishing line is safer to use than discs.

The disadvantage of the line is that it is only suitable for mowing short grass, because otherwise it often gets clogged. This is typical for both electric and gasoline scythes. When the grass wraps around the spindle, there is a lot of resistance on the shaft and it becomes damaged. In this case, the piston system can also fail (in gas scythes) or the electric motor can overheat and burn out (in electric scythes).

DIY trimmer coil repair

A trimmer, be it gasoline or electric, is the only correct solution for cutting grass in hard-to-reach places that a wheeled lawn mower cannot handle. Trimmers use metal knives or a special fishing line as a cutting tool, which is threaded into the trimmer reel. But, unfortunately, trimmer heads become unusable over time during use. Some problems can be fixed with your own hands, while others will require a complete replacement of the mowing head.

How to properly place a knife on a trimmer

Putting the knife on the trimmer is not that difficult. The manufacturer equips its tools with a special pin that allows you to lock the gearbox and a key with which you can unscrew the spool with fishing line. The most important thing is to observe safety precautions and the sequence of assembly and disassembly when changing cutting elements.

The algorithm for installing the knife on the trimmer is as follows:

Remove the protective cover;
We block the drive. To do this, you need to align two holes - in the shaft hub and in the gearbox cup. After aligning them, insert a pin into the holes;
Unscrew the spool with fishing line or the fastening nut holding the boot clockwise from the hub (if the trimmer has not yet been used);
Next, install the cutting knife so that the slots on the hub washer coincide with the recesses in the hole of the cutting disc;
Install the boot;
Tighten the fastening nut (counterclockwise) while holding the locking pin;
Tighten it using a tubular wrench;
We return the protective casing to its place.

As you can see, there is nothing complicated. Now you can safely start mowing the weeds on the site.

Trimmer coil structure

Mowing heads for trimmers come in a variety of designs, some simple and some complex. The figure below shows a semi-automatic trimmer head from a Husqvarna brush cutter (Husqvarna) disassembled.

This type of head is present in most gas mowers and electric trimmers, such as STIHL (STIHL), Patriot (Patriot), Champion (Champion), Bosch (Bosch), Huter (Huter) and others. The design of the mowing head is quite simple. It includes the following parts:

mowing head base;
button for semi-automatic cord feeding;
a spool ( reel ) into which the fishing line is threaded;
spring;
eyes - through them the fishing line comes out;
trimmer head cover;
fishing line (cord).

How to wind fishing line on a trimmer. How to remove the coil from the trimmer.#ViktorPolev

There are also simpler trimmer heads, shown in the following photo.

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

Algorithm for installing a knife on a trimmer

Replacing the blade on the trimmer is quite simple. Manufacturers include a key for removing the cutting attachment (spool with fishing line) and a pin designed to block the gearbox. To change the disk, you need to do the following:

remove the casing that performs protective functions;
insert the pin into the aligned holes located on the shaft and gearbox, and in this way block the drive;
if a spool with fishing line is installed, then unscrew it clockwise and find a nut to tighten the knife;

put the boot on;
blocking the gearbox with a pin, tighten the fastening nut, tightening it with a wrench;

The algorithm for installing a knife on a trimmer is demonstrated in detail in the video below.

Modern trimmers, for example, from, are easy to maintain. Replacing the cutting parts yourself will not be difficult.

When working, pay attention to safety precautions to avoid cutting yourself.

How to remove the reel and replace the line

Owners of trimmers, mostly beginners, become confused, bordering on panic, when the need arises 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.

Before threading the line into the spool, turn off the engine of the brush cutter or turn off the power to the electric trimmer to avoid injury that could occur if the cutting tool is accidentally started to rotate.
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 know that the thread on the shaft is left-handed. Therefore, you should turn the trimmer coil to the right, that is, clockwise.
Disassemble the mowing head. Most often, the head cover is secured with clips. To remove it, you will need to push these clips into the body, pressing the edges of the cover. If your trimmer is equipped with a semi-automatic mowing head that has a button on the bottom, then disassembling the attachment must be done carefully, since you can lose the spring, which sometimes flies out when the cover is removed.
Cut the required amount of fishing line. Typically its length is 5 meters. Use cord of the same diameter as specified in the instructions for the tool. It is not recommended to exceed the maximum diameter of the fishing line, as this will result in increased load on the engine and higher gas consumption.
Find the middle of the length of cord by folding it in half. You will end up with a loop.
Special grooves are cut inside the coil (there may be holes). Insert a loop of fishing line into this groove.
Wind the line onto the reel by turning it counterclockwise. The cord should be threaded as evenly as possible, the turns should lie without overlap and with good tension. When the winding is completed, leave the free ends of the fishing line about 20 cm long and fix them in the grooves located on the sides of the reel.
Assemble the mowing head. Before finally assembling the nozzle, do not forget to insert the spring and washer (if available). Place the reel in the housing and thread the ends of the cord through the holes or eyes.
Put on the cover and secure it with the latches.
Screw the attachment back onto the gearbox shaft, also securing it with a screwdriver. You will need to twist the trimmer coil to the left (counterclockwise).

Line does not automatically extend

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

Option 1 - biting occurred, i.e. clamping the cord between the turns. This problem usually appears if the user winds the line onto the reel unevenly, with intersecting turns, or winds 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, resulting in possible inter-turn clamping of the fishing line. To fix the problem, you will have to disassemble the reel on a trimmer and rewind the cord correctly, that is, in even turns with good tension.

Option 2 - the ends are too short and protrude from the head. The line may not come out when it hits the ground if its ends protruding from the head are not long enough (short). In this case, the centrifugal force is not enough to the line . Therefore, you need to stop the unit (turn off the engine or unplug the electric trimmer) and pull out the line manually, after pressing the button.

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

In the first case, the cord from third-party manufacturers may be made of low-quality and fusible materials that cannot withstand mechanical and temperature loads. Therefore, preference should be given to “branded” fishing lines.
But, if you nevertheless purchased a fishing line of unknown quality, and it often gets soldered during operation, then you can follow the example of some users who, after threading the cord into the reel, moisten it with either silicone grease (from a can) or mineral oil. This procedure greatly reduces the likelihood of soldering turns of fishing line together.
Also, the fishing line can become soldered if, during mowing, it hits a hard object (stone, fence, dry branch, etc.). As a result of this, it stretches a little and is pulled back into the head at high speed. The cord heats up due to friction, and its turns stick together. The only thing that can be done to eliminate this problem is to open the trimmer reel and rewind the line.

The cord spontaneously elongates

There are situations when a trimmer user notices a very rapid consumption of fishing line. At the same time, he never hit the button on the ground to lengthen the fishing line. The reason that the line spontaneously lengthens, being cut off by 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 fishing line into the reel, forget to install the pressure spring in the head, or completely lose it when opening the lid, and in the future, do not even suspect its existence.

Also, the line can be extended without using a button if the spring is weakened. If checking the spring has confirmed this fact, then it is necessary to place several washers under it to strengthen its clamping properties.

Problems with fishing line

Users of trimmers, both gas and electric, sometimes have problems with the cord. "Advanced" lawn mower owners can easily cope with the difficulties that arise by understanding why this happens, but for beginners it is a problem that has no rational explanation. But in fact, everything is resolved quite simply. The most common problems that arise with fishing line are as follows.

Rash

If the line breaks frequently, it may be due to the following reasons:

Rocks, small branches and other hard obstacles are found throughout the grass;

The user mows the grass right next to the fence, and if it is clean, it breaks the “tendrils” even faster;

Poor quality cord (it is recommended to buy a quality one);

The outputs in the mowing head are worn out, causing the line to wear down to the sharp edges of the bushings and break off (a complete replacement of the part is required).

High cord consumption

As a rule, the cord runs out quickly, often knocking over the ground with a semi-automatic head or pressing hard on it. The reel is unlocked and the extending line is cut with a knife. Another reason that the cord drains quickly is that the automatic head machine is not working properly: the user often slows down the motor while mowing. But, as we remember, the automatic head is designed in such a way that with each decrease in speed, a new part of the mowing line is supplied, so it is quickly consumed.

The thread doesn't hold

It happens that the thread unwinds if the spring in the semi-automatic head has relaxed. The rod is constantly pulled out and tightened by a knife mounted on the body, which increases its consumption. To check this, remove the cover and turn on the device. If the line is “rose”, you need to replace the spring.

Emergency situation

The reason that the cord unwinds after starting the device may also be a weakening of the spring inside the head. In addition, there are times when the mower flies when the unit is turned on and the spring installed in it is lost. Inexperienced users do not notice the absence of a spring and assemble this device without it. Therefore, the cord does not hold on, but flies away under the influence of centrifugal force.

The cord is not powered, the reel does not rotate

An automatic or semi-automatic head should feed the line without stopping the device. But if this doesn't work, the reasons could be:

The line is wound incorrectly on the reel so that the latter does not rotate;
The cord is wound unevenly, and the thread may get stuck between the turns (the thread must be wound carefully, turn on the thread without distortion);
Too short ends of the thread come out of the holes, which results in insufficient centrifugal force to pull them out, and the line does not feed (it is recommended that the length of the cord is always adjusted before starting the device by pulling it slightly);
The line is stuck together (to be discussed later).

The thread sticks together

This problem is most often associated with the use of a low-quality cord. When the machine is running, the trimmer head heats up and the low-quality fishing line melts in it, sticking together. In addition, filament sintering occurs when the line encounters a continuous obstacle. In this case, a sharp braking of the cord occurs, after which it is pulled into the head where it is attached. Some device owners recommend lubricating the cord with mineral oil or spraying silicone spray after winding it onto the bobbin. Others advise winding less thread on the spool. But it’s better to immediately buy a high-quality product, in the manufacture of which the manufacturer took into account the head overheating factor, and the thread will not stick.

The most famous versions of battery-powered braids are listed below.

Common mistakes

Although winding line is a very simple task, many beginners may wind the line incorrectly. Below are the most common mistakes.

Many people, when measuring thread, think that 4 m is a lot. Because of this, people often measure out less and therefore end up running out of line. Don't be afraid to measure out too much, because you can always cut off the excess.
In a hurry, some people do not follow the threading grooves inside the spool and wind the thread at random. This leads to the line flying out of the reel and can even cause injury.
For winding, you should use only the appropriate fishing line. This error is the most common. You need to monitor not only the thickness and volume of the fishing line, but also its type. You should not use the first line you come across for winding, which will not meet your goals. For example, you do not need to use a thread on young grass if you need to mow dead wood.
Do not turn on the device until it is completely wound and assembled. Although this is obvious, some people do this to check if everything is done correctly.
In no case should you confuse the direction of refueling, as this will overload the engine, and it will soon fail.

READ How to Properly Change Line on a Trimmer

It is common for beginners to make mistakes, so you must follow the tips given in this article.

To learn how to replace the line on your Patriot trimmer, see below.

Preparing to wind the fishing line

Before the winding process, you must first remove the reel with fishing line from the housing. Depending on the manufacturer, power and type (electric or gasoline), there are three design types of trimmers:

Compact trimmers with electric drive. Electric trimmer spool This type of tool has a bottom-mounted motor and head, which in turn has two side buttons for removing the bobbin. When they are pressed simultaneously, the upper part of the reel with fishing line is disconnected, and the lower part remains rigidly attached to the braid. Experts recommend disassembling on a level surface to prevent the spring from jumping out.
Motor- and electric scythes with a curved duralumin rod, not intended for working with a knife. As a rule, reels of such models are equipped with a special wing nut. Removing the spool should be done by holding the reel body with one hand and unscrewing the wing counterclockwise with the other.
Powerful gas trimmers and electric scythes with a straight bar. Trimmer with a straight bar This model provides the ability to install a knife. Removing the coil in such models is done using two keys recessed into the coil body. To install the trimmer knife, you need to align the hole of the reel and the rod, and then insert a device in the form of a steel pin (screwdriver, iron rod). After fixing the coil, the housing can be easily unscrewed clockwise by hand.

The procedure for installing the disc on the trimmer

Installing the blade on the trimmer is very simple. To do this, use the supplied key to disconnect the cutting attachment and a pin to lock the gearbox . The procedure is as follows.

First of all, you should unplug the electric trimmer, and simply turn off the gasoline trimmer. Disconnect the protective cover and move it aside.
Next, you need to align the holes on the gearbox and the shaft in order to insert a pin into them and lock the drive.
If a spool with fishing line was used, it must be unscrewed clockwise.
Then you need to find a nut to tighten the knife.
The next step is to install the knives. Trimmer owners often wonder which side to put the disc on. This should be done so that the markings with numbers and letters are on top.
Then you need to place the boot on top, and above it - a fixing nut, which must be tightened tightly with a wrench.
The last step is to install the protective cover.

As you can see, the procedure is very simple and the same for many brands, be it equipment or Husqvarna.

On a note! If the owner of the device wants to replace the disk back with fishing line, you can install the reel with it in a similar way.

We wind the fishing line

Slowly completed disassembly of the spool reel without losing its spare parts allows you to move on to the main task - winding fishing line into the reel. The technological features of the spool design and the number of working antennae determine the sequence of actions.

The process of winding fishing line onto a reel

After all the preparatory steps, we need to correctly determine how exactly the fishing line will be wound onto your device, by turning the lid or in the opposite direction.
We measure approximately 7 mm of cutting material and insert one end into the bobbin hole. It is worth noting that the fishing line is wound specifically on the style mower models on both sides. The direction of winding the line in such models is indicated on the bobbin itself.
The line is extended up to about 17 cm freely so that the ends can be cut off weeds. Let us add that it is not worth winding a fishing line onto a reel of enormous length. Leave a distance of approximately 5 mm from the fishing line to the edge of the bobbin.
The two ends of the fishing line are inserted into the bobbin holes. Both of these ends must be securely attached to the device body.
We insert the springs removed from the coil (if any) in the same way as they were removed, i.e. into the bobbin and the head body itself.
To determine whether you have correctly inserted the fishing line into the trimmer, you need to ensure that the element itself (spool) is easily inserted into the head housing of your device. If necessary, remove the free ends of the fishing line further out. To achieve this, you need to sharply pull the fishing line out of the groove through the holes in the bobbin.

So, let's say you figured out how to quickly, and most importantly, correctly wind the fishing line onto the reel of the STIHL trimmer. All you have to do is insert everything correctly into the grooves and secure the main cover to the device. Then you can press on the bobbin itself and make movements counterclockwise until you feel a stop. If you don’t feel the pressure, then most likely you have not threaded the line correctly and you will have to start all over again from scratch.

What can be used instead of fishing line

how to put fishing line in the mower Shtil.FS-38

If instead of a special cutting element, say a fishing line, you install a metal cable, then your trimmer can “turn” into a real dangerous weapon not only for you and your eyes, but also for all the people around you. This is explained by the fact that while the trimmer is operating, the steel cable will constantly operate, which will lead to tangling, and its small pieces can fly off in all directions at great speed.
The same thing can happen if you use copper wire instead of a steel cable, but in this case, the pieces coming off the copper wire will be slightly larger and can cause you even greater injury. And if, God forbid, you accidentally catch such a cutting element on your leg, then after this it is 100% guaranteed that there will be a deep cut in the soft tissues, and in some cases, all this can lead to the amputation of small limbs (fingers), legs and even arms. Therefore, our advice to you is not to use any other cutting elements other than fishing line, for your own safety and those around you.

Warranty production of the trimmer's factory refill will inevitably require replacement of the fishing line. Having a very rough idea of how to thread the line into the trimmer reel on their own, beginners are reluctant to take on this task. However, with some skills, mastering this simple science does not present any difficulties, and the similar instructions presented below will make this process as easy as possible.

This part should not be confused with an extension cord for a lawn mower on a reel, since despite the similar name these are two completely different elements.

In the first option, winding the cutting element is very easy:

There is a locking eyelet on the inside of the spool element.
One tendril of thread is inserted there.
The nylon thread must be threaded in the direction opposite to the rotation of the spool element.
Only 2 to 4 meters of fishing line will be useful. When the winding process is completed, put the small end of this cutting element out and fix it in the groove that is needed to fix the fishing line so that it does not unwind during operation of the mower.
If there is no special groove, then the end should be held with your hand so that the cutting element does not unwind during the upcoming collection of the element.
At the final step, you need to thread the outer end of the thread into a special hole located on the outside of the element. Subsequently, of course, insert the reel into the mower.

A couple of tips

If you have wound the fishing line correctly, then when you press the bobbin button, the cutting element should automatically be pulled out. The line for your mowing device is one of the most important elements, without which the trimmer may lose all its functionality. We can say that the line (cutting element) is the heart of your mower. Therefore, when buying fishing line, pay attention first to its quality. When purchasing fishing line from one company or another, be sure to compare it with the quality of the old fishing line.

First way

The prepared segment (in this case it is 4 meters) is bent approximately in half - one segment should be 15-20 cm longer, and is inserted into a special slot located on the dividing partition.

The fishing line is wound in the previously determined direction. This is done under tension, the line is carefully distributed. In this case, you need to wind the segment that is longer into the section that is closer to the button.

There are designs that do not provide for dividing the coil into two sections. This does not change anything, the fishing line is wound in a similar way. You just need to make sure that the segments do not overlap each other.

The segment that is located at the bottom of the coil should end first, i.e. the one closest to the fixing holes.

This tip is placed in a hole of the corresponding diameter. The line is securely fastened.

The long piece is wound another half turn. There it is similarly fixed. In this case, the segment intersects another section of the coil.

The long piece is wound another half turn.

The fixed ends of the wound fishing line are inserted into the holes in the trimmer spool body.

The coil is attached to the body. The ends of the fishing line are pulled up with force so that the fishing line previously fixed in the holes of the reel of the fishing line jumps out. This is easily determined by the characteristic sound (click).

The line replacement was completed successfully. In this case, you need to install it back on the trimmer and you can start cutting the grass.

It should be repeated that there is no need to remove the spool from the trimmer - this was done to illustrate the process of replacing the fishing line. You can disassemble the spool in place, wind it onto the reel and put it back.

The ends can and should be trimmed so that they do not hit the trimmer casing.
