How to change the line on the STIHL petrol trimmer

Changing the line in the trimmer: 2 easy ways

change, line, stihl, petrol, trimmer

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

In this instruction, we will walk through the entire replacement process step by step. Looking ahead, there are two ways to line the trimmer spool. There is no fundamental difference. the difference lies in the fact that in the first case one line will be refueled, folded in half, and in the second there will be two such lines.

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.

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.

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:

  • 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.

Method 2. two segments

fundamentally no different from the method The only difference is two wound pieces of fishing line, instead of one.

There are two special fixing sockets on the coil (see picture above).

They cling to it with a hook formed earlier on the fishing line, and begin to wind the fishing line.

Winding is carried out in a special order

The winding must be carried out in the following order: first the lower line, i.e. the one that is closer to the fixing holes at the bottom of the coil, and only then the top one, i.e. the one that will overlap the bottom section.

The tips are cut into the holes in the grass trimmer spool body. They are pulled up until they click, which means that the line has come out of the latches.

The tips are threaded into the holes in the grass trimmer spool body

The coil is fastened into the body. The line in the spool has been replaced.
