How To Put A Blade On A 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

How To Put A Blade On A 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!

How to replace a fishing line in any trimmer
So, first unscrew the nozzle. Do this by rotating the drum to the right. Here we have a drum in our hands with the remains of an old fishing line. We open it. Most often, the lid closes with latches, which can be opened with a screwdriver by threading it through the holes and pressing lightly. Or you need to squeeze the lock and turn the cover in the direction of the arrow. At the same time, the lid itself must be kept, as in drums with automatic supply of fishing line there is a spring, which, when straightened, can throw out all the internal parts of the drum. Gently pulling out the reel, we remove scraps of fishing line from it.

Now you need to take 5 meters of new fishing line and fold in half (to find the middle). In the middle part of the reel there is a recess (in some designs. A hole), for which we need to hook our fishing line. There is also an arrow on the reel showing the direction of winding. An important detail. If the reel has two compartments, then one half of the fishing line should be wound in one direction, and the other in the other. Finishing the winding, you need to leave 15-20 cm of fishing line free. There are also two recesses on the upper ring of the coil through which these free ends must be drawn. We coped directly with the winding itself.

The last step in the fishing line replacement process is to assemble the drum. First you need to put the spring and washers in their place. Then, holding the reel with one hand, with the other you need to thread the ends of the fishing line into the corresponding holes on the sides of the nozzle. After that, install the coil in its place, pulling the fishing line and trying not to displace the spring. When all the internal elements of the nozzle take their places, you can close the drum with a lid. You just need to make some effort so that the latches fall into place. Voila! The mowing nozzle is ready to go!
When choosing a fishing line for your motor scythe (gasoline or electric), you should dwell on some points, which we will discuss in detail.

Diameter of fishing line.
Engine power determines what maximum fishing line diameter can be used for a given scythe. For example, the manufacturer of an electric trimmer with a power of up to 1 kW recommends using a fishing line ø2 mm, and at values ​​of about 500 W. Only ø1.5 mm. Also, the manufacturer of any powerful trimmer with a curved bar recommends using a ø2 mm fishing line.
A gasoline engine is more durable than an electric one. Because there you can install a thicker fishing line, which means stronger, which allows you to mow more grass and work longer.
For straight grass barrels, you can select the fishing line according to the following simple algorithm: the engine size in tens of cubic centimeters corresponds to the diameter in millimeters. For example, for a Husqvarna 128R lawn mower with an engine size of about 25 cm3, a ø2.5 ± 0.2 mm fishing line should be used. For more powerful brush cutters with volumes of more than 40 cm3, only the geometric dimensions of the outlet openings of the mowing head. No more than 4 mm, are used to limit the diameter of the line.
So, a thin fishing line (about 1.5 mm) cuts well the cultivated lawn grass, and thick (for example, 3.0.3.5 mm) successfully destroys weeds and even young shrubs.

The shape of the fishing line.
The simplest and cheapest in production is a round fishing line. However, the requirements of ergonomics and environmental protection limit its use. Due to its physical properties, it creates an unacceptably high noise level (which is comparable to the noise of the engine itself). These are the classic Husqvarna round fishing line or Oregon RoundLine or Chipmaster.
To reduce the noise level produced by the fishing line, they give it a special shape. Make it spiral like Oregon DuoLine Plus (noise reduction by 15 dB) or with special transverse grooves like Husqvarna Whisper (-8 dB).
Following the school laws of physics, “working” part of the fishing line during mowing is only the end surface, and not the side surface. However to enhance “pungent” fishing line, i.E. To increase efficiency, the cross-section is changed to faceted: star-shaped, square or square with teeth. Oregon StarLine, Nylsaw or Flexiblade.
For example, according to experts, the Oregon Nylsaw fishing line, thanks to its square profile, is 27% “sharper” its analogue of circular cross section, which clearly affects the increase in the speed of mowing.
