How can you replace the line in the trimmer

Preparing for replacement

We disassemble the trimmer spool

For clarity, the mowing head (spool) was removed from the brushcutter. To replace the fishing line, you do not need to remove it, everything is done locally. It doesn’t take long.

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

The spool consists of the following:

• Spring case
• Cover with locking latches
• Button coil

The principle of operation is as follows. By pressing the button, the spool presses on the spring and comes out of the locking grooves in the spool cap. Holding in this state, the reel can be twisted, thereby adjusting the length of the line. When the button is released, the body spring returns the coil to its original fixed state.

Disassembled trimmer spool

On the bottom of the reel there are several holes for different diameters of the lines. They may differ from trimmer manufacturer. In some cases (like here) they are signed, in others they are not.

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

Holes for fixing the line

There are models without specifying the diameter of the consumable. Then, in order to find out what the maximum diameter of the scaffold can be used, it is tried on along the holes for the outlet of the fishing line from the trimmer spool body (see the figure below).

Fitting on the holes of the line output

The reel has two line sections separated by a baffle. They may not exist. They are needed only to delimit and facilitate the winding of the consumable.

Two sections for line

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

Determining the required line length

Now you need to figure out which way you need to wind it. To do this, many trimmer manufacturers apply special designations to the spools, such as in the figure below.

Special designation on the reel

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

Bobbin case designation

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.

Replacing the trimmer line: step-by-step instructions for replacing the trimmer line

Trimmers (they are also lawn mowers) are actively used by modern society for the care of lawns and other similar objects of horticultural farms. The tool is noted for its high efficiency, despite the questionable quality of cutting grass (compared to the usual peasant scythe. earth and sky). The main advantage of trimmers (lawn mowers) is high productivity with low expenditure of physical forces of the operator. However, over time, the trimmer’s cutting element (nylon scaffolding) wears out or gets damaged, making the trimmer a useless tool as a result. Hence, the task becomes urgent. how to replace the trimmer head and how to replace the trimmer head line? Let’s consider this process using the example of lawn mowers manufactured by “Black and Decker” and others.

Tool for giving and home

We carry out the winding of the fishing line

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

How do I load the line into the trimmer spool? Video instruction

The warranty production of the factory trimmer refueling will inevitably require line replacement. Having a very rough idea of ​​how to thread the line into the trimmer reel on their own, beginners are reluctant to take up this business. However, with some skills, mastering this simple science does not present any difficulties, and the similar instruction presented below will facilitate this process as much as possible.

Preliminary preparation

First of all, to wind the fishing line, you need to remove the spool (bobbin, spool) from the trimmer. specific actions will depend on the complexity of the configuration and the type of the product itself:

• small electric trimmers with a working position of the engine and spools at the bottom, as a rule, have side buttons on both sides of the bobbin. When pressed at the same time, the upper part of the spool together with the inner content for winding the line is detached, while the lower part remains on the trimmer. It is advisable to disassemble the bobbin on a flat, smooth place so that the spring included in the structure does not jump out and get lost;
• electric and gasoline trimmers with a curved bar without the possibility of installing a knife, as a rule, have spools with a special wing: in such designs, hold the spool in a stationary position with one hand, and rotate the locking reel on the bar with the wing nut counterclockwise with the other. After disconnecting the nut, the entire bobbin is removed.
• electric and gasoline trimmers with the ability to install a knife on a straight bar (for example, Calm trimmers) have a hole under the reel. To keep the rod stationary, a screwdriver or other suitable object is inserted into this hole and, with slow rotation, such a mutual arrangement is achieved when the screwdriver enters the hole and the bobbin is fixed. After that, the coil body is scrolled clockwise (with a left-hand thread) and removed from the trimmer.

For the second and third cases, the coils, depending on the design, are disassembled in different ways. In bobbins with a lamb, a lamb is unscrewed, in coils with latches, the latches are pressed and one part of the coil is released from the other. If the halves of the bobbin are connected by thread, then it is enough to turn them by hand in opposite directions until they are completely unscrewed.

Step two: removing the winding drum (spool) with line

The next step in the process is the removal of the winding drum with line from the inside of the head. You need to turn the head open side to see the line and spool. On the side of the head, find two grooves (eyes) through which the fishing line is brought out.

It is necessary to free the line from the holes by turning the drum. then carefully remove the coil from the head area. The winding drum of some models is spring-mounted. This point must be taken into account when performing the extraction operation.

The procedure for removing the trimmer spool with line from the inside of the head: 1. head assembly with spool; 2. extraction carefully with a small axial rotation; 3. extracted parts

The old line is completely removed from the reel. To remove the old trimmer line, you need to remove the wood from the locking loops and pull the free end. This method removes all the old winding. The same process is repeated on the second section of the drum. The master is recommended to use gloves when performing work.

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.

Installing a new line on the 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:

removing the trimmer head cover

At the first stage of disassembly, the 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 models of lawn mowers, it is initially provided for the dismantling of the trimmer head, for which the hex key included in the tool kit is used. 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

At the moment of squeezing the locking tab, you need to slightly turn and lift the trimmer head cover to remove the winding drum.

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.

Replacing the trimmer line: step-by-step instructions for replacing the trimmer line

Trimmers (they are also lawn mowers) are actively used by modern society for the care of lawns and other similar objects of horticultural farms. The tool is noted for its high efficiency, despite the questionable quality of cutting grass (compared to the usual peasant scythe. earth and sky). The main advantage of trimmers (lawn mowers) is high productivity with low expenditure of physical forces of the operator.

Hence, the task becomes urgent. how to replace the trimmer head and how to replace the trimmer head line? Let’s consider this process using the example of lawn mowers manufactured by “Black and Decker” and others.

How to replace the trimmer line?

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

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

It is convenient to work on changing the trimmer line when the mower is lying on the table, and the master who replaces the trimmer line has the ability to approach the tool from either side.

How to change the line in the trimmer and which one is better to choose

Since we examined the choice of a trimmer in the previous article, today we will tell you how to properly fill the trimmer with fishing line, and which one is better to choose based on the working conditions.

After you bought a trimmer and began to actively use it, sooner or later the question of replacing the fishing line will arise, since this is the most wearing element in the tool, intensive use of the trimmer will lead to frequent replacement of consumables.

What types of woods are there

The most common type of line that fits almost all reel types 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 with it, and even more so it will not cope with bush.

As a rule, the diameter that can be used to cut young grass does not exceed 1.6 mm. The thicker the thread, the more coarse grass it is able to overcome.

There are fishing lines with sharp edges in the form of an asterisk or a square, this option is more adapted to mowing dry grass just due to the existing sharp edges, but its disadvantage is greater wear and is inferior in strength to a 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 petrol cutters, since the exit of such a thread from the reel is difficult, it is used most often with discs into which segments are inserted. The disadvantage of such a product is its fragility.

Most often in gasoline trimmers with an engine with an output of more than 1.5 hp. use cords with a metal cable inside.

This thread is ideal for cutting dry grass and small bushes. 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 opponents.

How to remove or tuck the line into the trimmer

In order to wind the line, it will take about 10-15 minutes. What is a trimmer coil? Plastic body with a cassette inside, on which there is a special hook for easy winding of the 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 line of the required length. The photo below shows a few examples of different trimmer spools.

The bobbins of the trimmers, the motor of which is located at the very ground, have a different attachment to the axis of rotation, they have two buttons on the spool located on the sides that need to be wrung out, otherwise the replacement of the thread is no different from other cassettes.

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

To remove the spool with the fishing line, you need to unscrew the centrally located screw, but note that the thread is left there, 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 spool onto which the fishing line is directly wound.

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

After that, it is necessary to assemble the head in the reverse order, threading the ends of the cord into two corresponding holes.

If you have any doubts or it is not entirely clear how to load the line on the trimmer, we recommend that you look at how to properly wind the line in the petrol cutter.

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

Second way

Some spools provide a second method of securing the cord: you can charge 2 pieces of thread instead of one folded in half. The line is replaced according to the following algorithm.

• Before changing or loading a new thread into the spool, determine how many meters it will take using the method described above.
• Bend one end of the cord into a hook.
• Find the hole in the bottom of the bobbin for the line to be fixed, and insert the looped end of the thread into it.
• It is required to wind the cord according to the direction of the arrow to the required level not exceeding the spool diameter.
• Do the same for the second bobbin compartment.
• The assembly of the head is no different from the method that was given when threading the bobbin with a half-folded piece of fishing line was considered.

For Shtil brushcutters there is a very simple and quick way to change the line without disassembling the mowing head, which you can familiarize yourself with by watching this video.

The ends of the cord protruding from the holes in the casing can be cut to the required length after the part is installed in the trimmer. This can be done in two ways:

• turning on the trimmer (when rotating, the ends of the fishing line will be cut off against the knife fixed for this purpose on the protective casing);
• cutting off the excess ends with scissors so that they do not touch the casing body.

The second method is used if it was necessary to supply a large diameter cord, and the edging knife cannot shorten it.

If the filament has been loaded into the mowing head, but the length of the protruding ends of the cord is not enough, then they must be lengthened before starting the machine. this applies to the head with manual adjustment. However, there are cases when using a semi-automatic mowing head when, due to the insufficient length of the protruding ends of the cord, they do not automatically lengthen. In this case, it is necessary to turn off the unit (on an electrical device, it is necessary to unplug the plug from the socket), manually press the button located at the bottom of the part, and pull out a little line. After this procedure, the cord can again be extended due to centrifugal force if you set the maximum spindle speed.

Regardless of the thickness of the line you set, you should remember: in order not to constantly interrupt work and not change the line, you should avoid areas where the working tool can touch hard surfaces (stones, curbs, thick dry branches, etc.).

How to remove and disassemble a coil

Before starting the cord replacement process, trimmer users need to remove and disassemble the reel. Let’s see how to do it.

The trimmer mowing head consists of several parts: a cover, a spring (not on all models), a bobbin with a cord and a cover.

Attention! Before proceeding with any maintenance of the electrical unit, it must be disconnected from the mains.

In trimmers, 2 options for mounting the mowing head are most often used.

Line problems

Trimmer users, both gasoline and electric, sometimes have problems with the cord. “Advanced” mower owners can easily cope with the difficulties that have arisen, understanding why this is happening, and for beginners it is a problem that has no rational explanation. But in fact, everything is solved quite simply. The most common problems that happen with the line are as follows.

Changing the line to a disc or knife

When ennobling a personal plot, park areas and other places where it is required to mow various kinds of plants, it is often necessary to change the cutting tool in the trimmer. This is due to the fact that the standard cord installed in the mowing head can only handle grass. But when a bush or young growth of trees appears in the path of an employee, the line cannot cope with such a task, and it needs to be changed to a more efficient cutting tool.

Trimmer manufacturers have foreseen such situations, and supplemented their products with a mass of attachments in the form of knives with several “petals” or in the form of discs, similar to circular saws.

If you replace the fishing line with a knife with several “petals”, then this tool can mow both tall grass and plants with thick and dry stems. And by changing the line to a disc, the user of the brushcutter has the opportunity to cut down bushes or small trees.

Knives and discs are installed according to the following algorithm.

• The first step is to remove, locking the shaft, the mowing head (turn clockwise) or the boot nut, if the unit has not yet been used.
• Position the saw or cutter blade so that it fits over the small protrusion (bushing).

For a better understanding of the process of changing tools, you can watch this video.

The thread does not hold

It happens that the thread unwinds if the spring in the semiautomatic head has weakened. The line is constantly extended and cut with a knife installed on the cover, which increases its consumption. To check this, remove the cover and turn on the unit. If the line “climbed”, then you will need to replace the spring.

Cord breaks

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

• stones, small branches and other solid obstacles come across in the grass;
• the user mows the grass close to the fence, and if it is mesh, then it breaks off the “antennae” even faster;
• poor quality of the cord (it is recommended to purchase a quality one);
• the outlet holes in the mowing head are worn out, due to which the line is erased on the sharp edges of the bushings and breaks off (a complete replacement of the part is required).

Option

In this embodiment, the head is screwed onto the gearbox shaft. To remove it, you need to fix this shaft. To do this, in similar trimmers, for example, in the Huter and Champion, there is a hole through which you can insert either a thin screwdriver or a metal rod.

So, to remove the bobbin, follow 2 easy steps.

• Insert a screwdriver into the hole and lock the shaft.
• Grasp the head body and start turning it clockwise. Turn in this direction for the reason that the thread cut on the shaft is left.
