How to replace the line with a disc on a trimmer

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.

Changing the grass trimmer line: step-by-step instructions for replacing the trimmer line

grass 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 grass trimmer’s cutting element (nylon scaffolding) wears out or gets damaged, making the grass trimmer a useless tool as a result. From here, the task becomes urgent. how to replace the trimmer head and how to replace the line of the grass trimmer head? Let’s consider this process using the example of lawn mowers manufactured by “Black and Decker” and others.

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.

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 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.

Procedure for removing the coil of the grass trimmer with a fishing line from the inner area of ​​the head: 1. the head assembly with the coil; 2. remove carefully with a small axial rotation; 3. extracted parts

The old line is completely removed from the reel. To remove the old grass trimmer line, remove the wood from the retaining loops and pull on 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.

The final moment of the instructions

Usually, the process of changing the line on a particular model trimmer is popularly described in the accompanying documentation. Another question is that this documentation is often supplied in a foreign language, since the notorious lawn mowers for the most part are imported products.

Meanwhile, there is a much simpler, more economical and beneficial for human health and nature way. putting in order the lawns of an ordinary peasant scythe. Grass scythe blade:

  • does not “tear” the stems of grass,
  • does not uproot plants,
  • cuts neatly,

which is further accompanied by abundantly growing greens, and not the formation of dead wood as a result of the work of the grass trimmer.

What you need to know about grass trimmer line

A fishing line is a consumable that is made of nylon and serves as a cutting device. By means of this equipment, the grass is cut, which is ensured by rotating the tool head at a high frequency. This material has a different thickness, which depends on its application on the corresponding tools, electric low-power (from 1 to 1.6 mm), electric from 500 W (2-2.4 mm) and gasoline grass trimmers with brushcutters (from 2.4 up to 3.2 mm).

The more powerful the tool, the correspondingly thicker the cutting equipment should be. This affects not only the quality of the grass cut, but also the service life of the material. If you are wondering how to wind the coil of your grass trimmer, then it is time to change and reload the tool. With the onset of spring, this question is becoming more and more popular, so it’s time to figure out the step-by-step instructions for replacing the fishing line in the grass trimmer reel.

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.

The 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 inserted into a special slot located on the dividing wall.

The line is wound in the direction determined earlier. This is done in an interference fit, the line is neatly distributed. In this case, you need to wind a segment that is longer in 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 line is wound in a similar way. You just need to make sure that the segments do not overlap with each other.

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

This tip fits into the corresponding hole in diameter. The line is securely fixed.

A long segment is wound half a turn. There he is similarly fixed. In this case, the segment crosses another section of the coil.

A long segment is wound another half turn

The fixed ends of the coiled line are inserted into the holes in the spool body of the grass trimmer.

The coil is attached to the body. The ends of the fishing line are pulled with effort so that the fishing lines previously fixed in the holes of the reel jump out from there. It is easily identified by the characteristic sound (click).

The line was changed successfully. In this case, you need to put it back on the grass trimmer and you can start mowing the grass.

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

Tips can and should be trimmed to prevent them from hitting the grass trimmer cover.

Method 1. how to properly wind the line or put it on a reel and choose the required length

To implement this method, you will need to first prepare a fishing line of the required length (usually up to 4 meters). It all depends on the thickness of the equipment used, as well as the design of the coil. There is an easy way to find out the amount of line you need to refuel to charge the reel. To do this, wind the rig inside the coil until it is aligned with the side protrusions. In this case, the rigging should not go beyond these extreme protrusions.

The thicker the equipment used, the shorter its length will be needed and vice versa, the thinner, the longer the segment will be needed.

The instruction on how to properly tuck the harness into the aiming of the grass trimmer or brushcutter is as follows:

  • To begin with, a piece of fishing line that was prepared to be installed in a reel must be folded in half. In this case, one edge should protrude more than the second by 10-15 cm
  • After that, take the second end from the other side, and bend it in half. Move to it so that the measured protrusion of 15 cm is preserved
  • There is a slot in the inner baffle of the coil, into which the resulting loop should be inserted. The cut in the wall is shown in the photo below.
  • Next, we figure out the direction of winding the line. If you wind the rig in the wrong direction, then it will not function correctly, and you will need to redo the work. To insert the line and wind it in the correct direction, inspect the surface of the spool. It should indicate the direction of winding (in 99% of cases, this direction is indicated). What the direction indicator on the coil looks like is shown in the photo below.
  • This arrow-shaped pointer can also have the designation, as in the example above “WIND LINE”, which means the direction of winding. If the pointer is missing on the reel, then you need to look at the head. There is a direction of its rotation on the head, and in order to properly wind the line, wind it on the drum in the opposite direction to the indication of the arrow indicator. So, if the arrow is on the tip, then you need to wind in the indicated direction, and if it is not there, then you should wind against the direction of the arrow on the surface of the head
  • Having decided on the direction of rotation, you should start winding. Each end should be guided in its own groove. If there is no separator, then the equipment must be laid in the appropriate distribution order.
  • When almost all the fishing line is wound on a reel, you will need to do the following. place a short part in the hole of the side wall of the pickup, the protrusion of which should be up to 10-15 cm, and then do the same procedure with the other end, placing it in the hole on the parallel side
  • We insert the coil into the head, first passing the ends of the fishing line into the holes of the drum
  • We put the drum in place and, by pulling the ends of the line, we disengage them from the temporary clamps in the wall of the reel. After that, you can put on the cover until the latch engages.
  • At this point, the process of how to replace the fishing line on the trimmer is completed, and if necessary, you can cut only the ends (if their length does not suit), and install the assembled drum on the tool

With how to put the drum in place, no difficulties arise. There is a second way, how to charge the mowing equipment in the brushcutter. What is the difference and how the second method of threading the line onto the reel of the brushcutter is carried out, we will find out in detail.

Preparing for replacement

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 spool of the grass trimmer. 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:

replace, line, disc, trimmer
  • Spring casing
  • 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.

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 to prevent the scaffolding from unwinding when the coil is installed in the grass trimmer body. In other words, it makes it easier to change 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 body of the spool of the grass trimmer (see the figure below).

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.

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.

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.

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.

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 first 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.

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.

On a reel with two antennae

In bobbins of this type, it is necessary to inspect the inner side of the coil and determine the number of grooves for winding the cord provided in it.

Important! If there is only one groove in the coil, then both antennae must be wound along a common groove, if two, then along separate tracks.

For winding, you need to take a piece of fishing line with a length of two to three meters. For spools with one groove, thread the line through the hole, align the whiskers, align and wind on the spool in the opposite direction of its rotation during operation. If fixing grooves are provided, thread the ends of the cord through them, then pull them out into the outlet, then close the coil and put it back on.

For double-fluted spools, the difference is that the string must be folded in half. Next, you need to charge the middle of the fold into the groove between the grooves, then wind each of the pieces of fishing line along its own path, fix the antennae and assemble the coil as well as a spool with one track.
