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

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

What types of woods are

The most common type of fishing line, which is suitable for almost all types of coils. round cord. This is an ordinary fishing line suitable for mowing juicy grass, but mowing dead wood with it will be much more difficult, and even more so it can not cope with the bush.

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

There are fishing lines with sharp edges in the form of an asterisk or square, this option is more suitable for mowing dry grass just due to the existing sharp edges, but its disadvantage is more wear and tear 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 they are used only on lawn mowers, 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 this product is its fragility.

Most often in gas trimmers with an engine power of more than 1.5 hp apply cords with a metal cable inside.

This thread is ideal for mowing dry grass and small bushes. The presence of a core positively affects 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 remove or refill a fishing line in a trimmer

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

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

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

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

To remove the reel with fishing line, it is necessary to unscrew the screw located in the center, but note that the thread there is left, so you have to turn it clockwise, this is done specially so that during operation it does not open under the influence of centrifugal force.

Next, using a screwdriver, disassemble the head and take out the reel, on which the fishing line is directly wound.

Having measured the necessary length and folded in half, you need to fill the fishing line into the reel, removing, in the end, its ends opposite each other (for this there are special slots for fixing).

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

If you have doubts or it’s not entirely clear how to charge the fishing line to the trimmer, we recommend watching the video: how to wind the fishing line into the lawn mowing properly.

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

Many, having developed a factory line on a newly acquired trimmer, try to rewind a new one, but they cannot, because they do not know how to wind the line onto the reel spool (bobbin). It seems that there is an instruction, but it still doesn’t work out. Let’s try to deal with this issue in this article.

So, to rewind the fishing line, you need, for starters, to remove the reel from the trimmer. it will be more convenient. The removal method will depend on the type of trimmer.

Remove the coil from the trimmer

On small electric trimmers with the bottom position of the engine (when it is when working near the ground), the coil usually has two keys on its sides. We click on them and disconnect one half of the coil body from the second, which remains on the trimmer. Together with the first half, the inner part is taken out, on which the fishing line is directly wound. When parsing, be careful: there is a spring inside that can fly out and get lost.

On electric and petrol trimmers with a curved bar (it is still not possible to put a knife on such trimmers), you need to grab the coil body with one hand, and with the second hand you need to start turning the lamb on it. It is he who fastens the coil to the trimmer bar. Having unscrewed the lamb, carefully remove the entire coil, being careful not to lose the spring inside.

On electric and petrol trimmers with a straight rod and a gearbox at its end (in addition to fishing line, you can also install a knife on such trimmers) we look for a hole under the coil, insert a screwdriver into it, for example, rotate the coil quietly until the screwdriver penetrates even deeper, and the coil will lock. Now twist the entire coil clockwise (since the thread is left) and remove it from the trimmer. Then we disassemble the coil. It can be assembled using latches or twisted by a lamb. If the coil is on latches, then we press on the sides on the base of the latches so that they bend and release one half of the coil body from the other. We just twist the lamb. There may also be a third type of connection of two halves of such a coil: with it, you need to grab the lower part with one hand, and the upper one with the other, and start turning them in opposite directions. When disassembling such a coil, you must also make sure that the spring inside is not lost.

Now, having removed and disassembled the coil, we proceed, in fact, to winding.

Winding process

If your coil is designed to work with only one antennae, then everything is simple. You need to rewind 2-4 m of fishing line (depending on the size of the reel), find the hole fixing the line on the inside of the reel, insert one end of the line there and start reeling the line in the direction opposite to the direction of rotation of the reel on the trimmer. On the inside of the reel, they usually indicate an arrow, in which direction to wind the line. After winding up the fishing line, we leave a small piece of it unwound to expose it. We fix this piece in a special groove located on the inside of the reel and designed so that the fishing line does not unwind at the time of collection of the reel. If there is no such groove, then you will have to hold the fishing line with your finger to prevent it from unwinding during the further collection of the reel. Next, we take the outer part of the reel and thread the outer piece of fishing line into the existing hole, collect and put the reel back on the trimmer.

If the coil is designed to work with two antennae, then do the following. On the inside of the reel, we see how many grooves are available for winding fishing line. There may be one or two. If there is one groove, then both antennae are wound along this same groove. If there are two grooves, then each antennae is wound on its own groove. The reel with one groove should have a through hole into which the line is threaded. Unwind 2-4 m of fishing line, thread it through this hole so that on each side of the fishing line sticks out equally. And at the same time we wind both antennae of the fishing line in the same direction, opposite to the direction of rotation of the coil on the trimmer and coinciding with the direction indicated by the arrow on the inside of the coil. We leave a little fishing line unwound, we fix the ends in special grooves, and if they are not there, hold them with our fingers. Pass both ends into the holes on the outer coil body. We assemble the coil and attach it to the trimmer.

If there are two grooves, we fold the piece of fishing line 2-4 m long in half, insert the loop obtained at the bend point into the groove between the two grooves, and simultaneously wind both ends of the fishing line in each groove. Further actions are similar to the previous option.

There are still reels in which the line is threaded through a through hole on the inside. After that, the ends of the fishing line, without winding, are threaded completely through the holes on the outer casing of the reel, the reel is assembled and the button, which is usually pressed, is rotated so that the line can be released during operation as it wears out. Turn the button. the line itself is wound inside. At the same time, turning it in the “wrong” direction will not work, since it can only spin in one direction. If you get used to it, then you can wind the line onto such a reel without even taking it apart. you just need to combine the through hole of the inner drum with the holes on the outer case of the reel, and then thread the line into them.

That’s all for the matter. Good winding!
