Trimmer Stihl Line Replacement

Changing the line in the trimmer: 2 easy ways Change the line in the trimmer. How to disassemble the trimmer spool? How many ways are there to install a line? Step by step instructions with photos.

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 the segment that is located at the bottom of the coil, i.E. The one closer to the fixing holes.

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

A long segment is wound another half 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 trimmer spool body.

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. This is easily identified by the characteristic sound (click).

The spool with the button snaps into the trimmer spool housing.

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

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

The tips can and should be trimmed so that they do not hit the trimmer cover.

Changing the line in the trimmer: 2 easy ways

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

We fill the line in the trimmer.

I want to devote today’s article to the sore subject of summer residents and gardeners of the entire post-Soviet space “How to fill the line in the trimmer.” Not many trimmer manufacturers answer this question in their instruction manuals. Therefore, it is difficult for simple gardeners to figure out how to do it correctly.

I want to start with a brief description of the technical characteristics of the trimmers.

So, trimmers are electric and gasoline. The cutting element for trimmers can be a line and a knife. The line is ordinary, four. Pentahedral and intertwined (in the form of a pigtail). Knives come in 2, 3 and 4 bladed knives. There are also plastic and metal knives.

The line feed system from the trimmer is manual, semi-automatic and automatic.

The development engineers who create new models of trimmers clearly calculate the diameter (thickness) of the line and the number of knife blades, according to the power of the trimmers. Otherwise, the motor is overloaded, resulting in damage. And these are additional and significant costs.

Trimmers on the market today:

With one nozzle. Only a line.
With two nozzles. A fishing line and a three-four-blade knife.
With one nozzle. Only three to four bladed knife.

Our Kulibins long ago learned to improve any mechanisms. So, for example, some gardeners make successful, in their opinion, replacement of fishing line with a metal cable, or fishing line. But at the same time, they do not think about the safety of their own and their loved ones, because, like a cable with the power of a working trimmer, it can easily break out and not only injure the mower and others, but leave him crippled for life. Using a fishing line can and gives a better effect, I have never personally tried it than a trimmer line, but such work has a number of inconveniences: when it comes into contact with hard objects, it loosens or can simply be pulled out of the reel without limit.

So, what is called closer to the topic. Here is an example of how to thread the line into the trimmer (Trimmer BOSCH Art 30). Everything is very simple. We started.

After you have chosen the line for refueling, you need to cut off the required amount of line, because all the line in the skein will not be wound into the reel.

Cut off and start winding.

Remove the coil and the protective cover from the coil.

They took it off. We fasten one end of the line into the gap and carefully and evenly wind the line.

The amount of line should be such that the protective cover of the reel closes and the line on the reel unwinds a little by itself.

We put the other end of the line into the hole in the protective casing.

Next, we take the coil and the protective cover of the coil. We squirt the end of the line from the reel into the metal hole on the protective cover of the reel. We tighten the line a little.

We put it all on the trimmer. Turn the coil clockwise until it clicks.

They fixed it. Now we connect the trimmer to the network. We put the trimmer in the starting position for work. We turn on the trimmer. Excessive line length will be cut with the trimmer blade.

Coil in trimmer

That’s all we start working.

Spare coil storage space

It is very simple to install such a fishing line into the reel. According to the internal scheme inside the reel. We insert the center of the line with a metal mount in the upper part of the reel, and draw the ends of the line along the grooves and bring it out.

Thick line

It is stored at the top of the trimmer body.

Preparing for replacement

We disassemble the trimmer spool

For clarity, the mowing head (spool) was removed from the lawn mower. To replace the fishing line, you do not need to remove it, everything is done in place. 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
  • Reel with button

The principle of operation is as follows. By pressing the button, the spool presses on the spring and comes out of the fixing 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 (as here) they are signed, in others they are not.

These holes are needed to fix the line when replacing 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 loess length. 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 reels, 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.

What types of woods are there

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

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 precisely 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 lawn mowers, since it is difficult for such a thread to come out of the reel, 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 listed opponents.

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

Since we considered 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, then intensive use of the trimmer will lead to frequent replacement of consumables.

How to remove or tuck the line into the trimmer

It will take about 10-15 minutes to wind the line. What is a trimmer coil? Plastic body with a cassette inside, which has 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 near the 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 screw located in the center, 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 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.
