How to replace line in any trimmer
How to replace line in any trimmer
So, first unscrew the nozzle. This should be done by rotating the drum to the right. Here we have a drum with the remnants of an old fishing line in our hands. We open it. Most often, the lid is closed with latches that can be opened with a screwdriver, threading it through the holes and slightly pressing. Or you need to squeeze the latch and turn the cover in the direction of the arrow. In this case, the lid itself must be held, since reels with automatic line feed have a spring that, when straightened, can throw out all the inner parts of the drum. Gently pulling out the reel, remove the scraps of fishing line from it.
Now you need to take 5 meters of new line and fold it in half (to find the middle). In the middle part of the reel there is a notch (in some designs. a hole), for which we need to hook our fishing line. There is also an arrow on the spool showing the direction of winding. An important detail. if the reel has two compartments, then one half of the line should be wound in one direction, and the other in the other. When finishing winding, you need to leave 15-20 cm of line free. There are also two notches on the top ring of the coil, through which these free ends need to be passed. We dealt with the winding itself.
The last step in the line replacement process is to assemble the drum. First you need to install 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 line into the corresponding holes on the sides of the nozzle. After that, install the coil in its place, tightening the line and being careful not to dislodge 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 to ensure that the latches fall into place. Voila! The mowing head is ready for use!
When choosing a fishing line for your motor scythe (gasoline or electric), you should dwell on some points, which we will talk about in detail.
Engine power determines which maximum line diameter can be used for a given braid. For example, the manufacturer of an electric trimmer with a power of up to 1 kW recommends using a line of ø2 mm, and for values of about 500 W, only ø1.5 mm. Also, the manufacturer of any heavy duty curved bar trimmer recommends using a ø2mm line.
The gasoline engine is more durable than the electric one, so you can install thicker line there, which means stronger line, which allows you to cut more grass and work longer.
On grass cutters with an even bar, you can select the line according to the following simple algorithm: the diameter in millimeters corresponds to the engine volume in tens of cubic centimeters. For example, for a Husqvarna 128R lawn mower with an engine capacity of about 25 cm3, use a line of ø2.5 ± 0.2 mm. For more powerful hedge trimmers 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 the limitation of the diameter of the line.
So, a thin fishing line (about 1.5 mm) cuts well cultivated lawn grass, and a thick one (for example, 3.0-3.5 mm) successfully destroys weeds and even young shrubs.
The simplest and cheapest to manufacture is a round line. However, the requirements of ergonomics and environmental protection limit its use. due to its physical properties, it creates an unacceptably high level of noise (which is comparable to the noise of the engine itself). This is the classic Husqvarna round line or Oregon RoundLine or Chipmaster.
To reduce the noise produced by the line, it is given a special shape. they 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 line during the mowing process is only the end surface, not the side surface. However, to increase “sharpness” fishing line, i.e. to increase efficiency, the cross section is changed from round to faceted: star-shaped, square or square with teeth. Oregon StarLine, Nylsaw or Flexiblade.
For example, according to the calculations of experts, Oregon Nylsaw line, due to its square profile, by 27% “sharper” its counterpart with a circular cross-section, which clearly affects the increase in mowing speed.

How to change the line on the trimmer
Below we have provided step-by-step instructions for replacing the trimmer thread.
The first thing to do is to unplug the tool and turn off the engine. Then you need to remove the trimmer head. This can be done using a simple screwdriver and dropping it into the hole of the gearbox to prevent the shaft from turning. And then just unscrew
They are usually unscrewed in a clockwise direction, but different models have different mechanisms, so it may have to be turned in the opposite direction. But if suddenly, for some reason, you cannot figure it out, then we strongly recommend that you refer to the user manual to understand how to disconnect it.
Second. After removing the mowing head, open it. This can be done by means of clamps that are located opposite each other. By pressing on them, you can remove the head cover, and then pull out the spool on which the line is wound. By pulling it out, you can determine what type it belongs to. There are one-piece and two-piece bobbins
We analyze how to thread the line into the trimmer spool in two versions
So, there is only one option. we load the line into a single-section reel. The prepared piece of thread is folded in half and pushed into the spool. Then, we begin to wind both ends in the same direction, which will be indicated by the arrow on the spool. At the end of winding, do not forget to make sure that different ends of the thread are looking in different directions.
Option two. winding the line with a two-piece reel. The pre-prepared thread is divided into two parts, and its ends must be fixed: this must be done by placing them in special fasteners
Changing Mower Blades (Scag)
Winding is carried out, as in the first case, according to the arrow indicated on the spool. Both segments should be wound so that they do not intersect. Further, the ends of the thread should be fixed in the grooves and divorced on opposite sides.
The spring is then inserted into the reel and the whole thing is placed in the mowing head. When placing the spool in the trimmer, you need to gently hold the spring parallel while inserting the line into the slots on the mower head. And in the end, it just needs to be secured with the final part, that is, with a lid.
After threading the trimmer, you need to check it. If you did everything correctly, everything will work, but if you make a mistake, we recommend that you read the article again, or even better, if you watch the video on how to install a line on a reel in a trimmer.
How to remove the line from the trimmer reel
Over time, the cutting element of the head wears out, and it becomes necessary to pull out the remnants of the old line. Not everyone knows how to do this. Our step-by-step instructions plus a video on how to pull the thread from the trimmer spool, which you can find on the net, will help in solving this issue.

Hard ? Of course not. But if, nevertheless, doubts creep into you that for some reason you cannot do this, then of course find and watch the video how to pull out or how to wind the thread on the reel of lawn mowers.
How to wind the line onto the trimmer spool
05 July 2018
The trimmer is a great solution for those who have a large garden or lawn near the house that needs to be constantly trimmed. But like any other tool, sometimes it requires intervention. After some time, it will become necessary to replace certain elements, and this will have to be learned.
How can this be done? To replace the main cutting element, you must first select it correctly. In principle, the operator’s manual for lawn mowers should indicate the diameter of the thread to be used in it.
When you have acquired the required cutting element, try to install it correctly. It should be noted that there are a huge number of videos on the Internet that will help you figure out how to properly thread the line into the trimmer coil.
How to replace the line on an electric trimmer
In fact, it makes no difference which oblique you use, be it electric or gasoline. Threading is the same. The only difference is that if you use a gas streamer, you get more freedom, since you are not limited by the cable that is present on the electric streamer.
Yes, do not hesitate to use the special videos on installing or threading the line in an electric scooter, which can teach you much faster than simple reading.
Removing the coil from the trimmer
On small electric bottom motor trimmers (when operating near the ground), the reel usually has two buttons on the sides. 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 also taken out, on which the fishing line is directly wound. When disassembling, be careful: there is a spring inside that can fly out and get lost.
On electric and gasoline trimmers with a curved bar (on such trimmers it is not yet possible to put a knife), you need to wrap the coil body itself with one hand, and with the other hand you need to start rotating the lamb on it counterclockwise. It is he who attaches the coil to the trimmer bar. Having unscrewed the lamb, carefully remove the entire coil, trying not to lose the spring inside.
On electric and gasoline trimmers with a straight bar and a gearbox at its end (on such trimmers, in addition to fishing line, you can also install a knife), we look for a hole under the coil, insert, for example, a screwdriver into it, quietly rotate the coil until the screwdriver crawls even deeper, and the coil will lock. Now we turn the whole coil clockwise (since the thread is left-handed) and remove it from the trimmer. Then we disassemble the coil. It can be assembled using latches or twisted with a lamb. If the coil is on latches, then 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 unscrew 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 part with the other, and start turning them in opposite directions. When disassembling such a coil, you also need to make sure that the spring inside is not lost.

Now, having removed and disassembled the coil, we proceed, in fact, to winding.
How to properly wind the line on the trimmer spool
Many, having worked out the factory line on a recently purchased trimmer, try to wind a new one, but cannot, because they do not know how to properly wind the line on the spool (bobbin) of the trimmer. It seems that there is an instruction, but it still does not work. Let’s try in this article to deal with this issue.
So, in order to wind the line, you first need to remove the coil from the trimmer. this will be more convenient. The removal method will depend on the type of trimmer.
If your coil is designed to work with only one tendril, then it’s simple. You need to rewind 2-4 m of fishing line (depending on the size of the reel), find a fixing hole for the line on the inside of the reel, insert one end of the line there and start winding 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 with an arrow in which direction to wind the line. Having reeled the fishing line, we leave a small piece of it unwound in order to expose it outside. We fix this piece in a special groove located on the inner part of the reel and designed so that the line does not unwind at the time of collecting 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 coil. Next, we take the outer part of the coil and thread the outer piece of fishing line into the existing hole, assemble and put the coil 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 look at how many grooves there are for winding the fishing line. There may be one or two of them. If there is only one groove, then both tendrils are wound along this one groove. If there are two grooves, then each antenna is wound along its own groove. A reel with one groove should have a through hole through which the line is threaded. We unwind 2-4 m of fishing line, thread it through this hole so that it sticks out equally on each side of the fishing line. And we simultaneously 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 of the fishing line unwound, fix the resulting ends in special grooves, and if they are not there, we hold them with our fingers. We pass both ends into the existing holes on the outer casing of the coil. We collect the coil and attach it to the trimmer.
There are also reels in which the fishing line is threaded through a through hole on the inside. After that, the ends of the line, without winding, are threaded completely through the holes on the outer body of the reel, collect the reel and begin to rotate the button, which is usually pressed, in order to release the line during operation as it wears out. Rotate the button. the fishing line itself is wound inside. At the same time, it will not work to turn it in the “wrong” direction, since it can only rotate in one direction. If you get used to it, you can wind fishing line on such a reel without even disassembling it. you just need to combine the through hole of the inner drum with the holes on the outer body of the reel, and then thread the fishing line through them.
That’s all on this issue. Happy winding!

Step 3. disassemble the coil
After the coil is removed from the head, it must be carefully disassembled. It is better to do this on an already mown area, because there may be a spring inside the coil, which will be quite difficult to find in the highest grass. Electric trimmer wiring diagram with half electric trimmer As you have seen. After disassembly, we will have three parts on our hands: the body (top cover), the protective casing and the coil itself.
Coil mechanism wedges under load
If the coil mechanism wedges under load, then there is a high probability that the driven or driving gears will need to be replaced. To determine, diagnostics will be required, which consists in disassembling the case and visual inspection of the transmission mechanism with the definition of defective parts. The problem arises from the poor-quality material of the gears and toothed shafts, as well as from the solid service life of the inertia gear. Symptoms of a malfunction initially appear as light tapping inside the body, subsequently turning into a limp when the handle is scrolled, and then into its jamming and jamming even at minimal loads. It should be borne in mind that to fix the problem, you will need spare parts that are suitable in terms of parameters.
In most cases, in gasoline trimmers with an engine power of more than 1.5 hp. use cords with an iron cable inside. in this video I show how to disassemble the coil from a gasoline trimmer, as well as how to properly wind the fishing line on it. Look carefully at the video I have on a similar trimmer on how to replace the fishing line in. This thread is perfect 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.
Usually, the diameter, which can be used for mowing young grass, does not exceed 1.6 mm. I have on a similar trimmer how to remove the coil from the trimmer, and meanwhile the vegetable garden is overgrown. The thicker the thread, the more coarse grass it is able to overcome.
There are fishing lines with sharpened 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 drawback is greater wear and is inferior in strength to a round cord.
There are fishing lines with improved aerodynamics with corresponding dents, scales and notches, a similar product makes less noise, but it is used only on lawn mowers, since the exit of such a thread from the reel is difficult, it is used in most cases with discs into which segments are inserted. This video is about how to change the air filter on your Husqvarna trimmer (lawn mower). The disadvantage of such a product is its fragility.
Spiral line feed
The feeding of the line in a spiral when casting lures is one of the most common problems in the operation of spinning devices, which is solved in a rather simple way, because the problem of incorrect operation lies in the clogging of the line guide roller. The essence of repairing a spinning reel when this problem occurs is to clean the line laying mechanism from dirt.
You will need to disassemble the line guide roller, following the recommendations presented in our article in the previous chapters, and remove visible blockages with a brush, followed by washing the parts. Having lubricated the assembly again, it is sequentially assembled and the device is comfortably operated.
