How to install a trimmer line on an electric grass trimmer spool

On small electronic trimmers with a bottom-mounted motor (when it’s near the ground when working), the spool usually has two buttons on the edges. Press on them and disconnect one half of the spool body from the 2nd half, which remains on the trimmer. Together with the first half is removed and the inner part, which exactly and winds up a line for the trimmer. When disassembling be careful: inside there is a spring that can be lost.

On electronic and gasoline trimmers with a bent rod (such trimmers still would not be able to put a knife) must be embraced by the coil body itself with one hand and the 2nd hand must start turning counterclockwise existing on it drums. Exactly, it strengthens the coil to the boom trimmer for grass. Unscrewing the thumbscrew, carefully remove the entire spool, trying not to lose available inside the spring.

On electronic and gasoline trimmers with a straight boom and gear at its end (in such trimmers for grass except for fishing line can be set to the same knife) are looking for under the spool hole, put it in, for example, screwdriver, quietly spin the spool, screwdriver does not fit deeper, and the spool will be fixed. Now turn the entire spool clockwise (because the thread is left-handed) and remove it from the grass trimmer. Next we disassemble the spool. It can be assembled with snaps or twisted with a wingnut. If the reel is on the latches, then press around the edges on the base of the latches so that they will bend and release one half of the reel body from the other. We simply unscrew the cock. May be to the same 3-th type of connection 2-half of the coil: it needs one hand to grab the lower part and the other. the upper, and start turning them in opposite directions. Disassembling a coil, it is also necessary to look to not lose the available inside the spring.

How to change a line for a trimmer on a trimmer?

Grass trimmer line replacement with step-by-step instructions will allow even an inexperienced in such matters lawnmower owner to perform quite a complicated job.

However, before you start work on changing the line on the trimmer, it is necessary to ensure the safety of the work. In particular, you should take precautions against careless or spontaneous activation of the lawnmower:

  • prevent accidental start,
  • remove the battery (if used),
  • place the tool in a convenient location for operation.

Works on grass trimmer line replacement are conveniently performed when the lawnmower is lying on the table, and the master, who performs the grass trimmer line replacement, has an opportunity to step up to the tool from any side.

Grass trimmer head cover removal

The first stage of disassembly is removing the grass trimmer head cover. Using the Black and Decker trimmer models and others as an example, to remove the cover it is usually sufficient to apply some pressure to release the locking latch, which is located on the side of the head body.

On some models of lawn mowers initially provides for the dismantling of the trimmer head for the grass, for which the hex key included in the tool kit is used. The head is usually held by two or three screws, which are accessed through the side holes of the back decorative cover.

The cover of the head, where the fishing line spool is installed, is usually held in place by a latch. Sufficiently, with some effort to squeeze the tongue-latch and a little turn the cover, after which the cover is easily removed At the moment of squeezing the tongue-latch should be slightly turned and lift the cover of the grass trimmer head to remove the winding drum.

Step two: Removing the filament drum (spool)

The next step in the process is to remove the winding drum with fishing line from the inner area of the head. Turn the head with the open side in order to see the trimmer line and the spool. On the side of the head to find two recesses (eyelets), through which the line for the trimmer is brought out.

Release the line for the trimmer from the holes by rotating the drum. Then carefully remove the spool from the head area. Some models have the filament reel mounted on a spring. This point must be taken into account when performing the extraction operation.

The procedure for removing the grass trimmer spool with fishing line from the inner area of the head: 1. head assembly with spool; 2. extraction carefully with a small axial rotation; 3. extracted parts The old grass trimmer line is completely removed from the spool. To remove the old grass trimmer line, you must remove the line from the loops and pull the free end. This method removes all old winding. The same process is repeated on the second section of the reel. It is recommended that the technician wear gloves when carrying out the work.

How to remove the reel from a grass trimmer and retrieve the line for the trimmer

Initially, before tucking the trimmer line into the grass trimmer spool, it must be removed from there. Reel or guide is a device that is located inside the mowing head, reel or drum. The heads come in different types (depending on the manufacturers), but the principle of changing the line on the spool is the same for all. The first thing to understand is how to remove the head from the tool, as well as how to get the drum with a fishing line out of it.

That’s interesting!Changing the accessories can be made directly on the tool, but if you perform it for the first time, it is still recommended to remove the head, and study the detailed process of winding. After the technology has been mastered, you can perform replacement work on the trimmer trimmer or gasoline mower. The instruction on how to unscrew the manual head on the trimmer is as follows:

    Turn the tool upside down and, if necessary, clean it. Grasp the cover locks (on the mowing head) symmetrically with two fingers of one hand. After gently pressing them inside, remove the protective cover from the drum

This process is not difficult, and as you understand, there is no need to dismantle the entire head, if you know how to perform the replacement. When disassembling, consider such nuances:

  • It is advisable to periodically remove the head to prevent corrosion of the threaded joint. If you have never unscrewed the screw, it may be difficult or even impossible to do so if necessary
  • If a screw has a four-sided head boring, then to unscrew it, you should choose a screwdriver or bits of the appropriate size to prevent slipping of the facets on the head
  • When reassembling the unit, the threaded seating should be treated with a lubricant such as solidol or machine oil
  • If the facets have adhered to the screw, special tongs could be used to unscrew it
  • There are reels that do not require prior disassembly. To disassemble them, you should take hold of it, and rotate in the opposite direction of the clockwise direction

Knowing how to disassemble the drum, you should continue to figure out the process of replacing the grass trimmer line. The video below shows a detailed process on how to open the grass trimmer reel and disassemble it.

How to wind the line for trimmer on the grass trimmer spool

Threading a line into the reel of the tool may not seem like a simple thing to do. But it is enough to study this process carefully. and in the future all the necessary actions will be performed without any difficulty.

To find out how to tuck the line for the trimmer into the grass trimmer, it is worth reading this guide. The step-by-step instructions below take into account the peculiarities of the spools of different types of trimmers, so it is applicable to any tool.

  • The fishing line reel is the bottom extreme part of the grass trimmer. The first thing to do, of course, is to remove this head from the tool. To do this, you need to fix the rod (or, in other words, the shaft) on which the coil is attached. You need to fix it so that it does not twist. The easiest way to do it is to put a kind of stop (preferably a metal one) between the thread of the shaft through a special hole. When the shaft is locked, you can unscrew the spool.
  • At this stage, you must remove the bobbin from the head, to which the line for the trimmer is attached. To do this, you will need to disassemble the head into elements. To do this, first locate the retainer on the bobbin case. It is located on the circumference of the product and is similar to a button. When the catch is found, you must press on it firmly. Keeping the latch pressed, turn the head cover clockwise. Then remove the cover and take out the bobbin.
  • A tight spring is placed between the bobbin and the head. It should be set aside for a while, so it does not interfere with the winding process. Before you start the stage of winding the fishing line, you need to inspect the bobbin. If there is any old fishing line left on the spool, remove it. When the bobbin is clean, you can start to prepare a new spool.
  • From the roll of new fishing line prepared in advance it is necessary to measure and cut off six (maximum seven) meters. The bobbin should be at hand.

At this point, actually begins a key stage, which is devoted to this article.

The first method of winding fishing line

The necessary amount of line is cut. Now you need to carefully inspect the bobbin to see what type it is. This depends on how it is to wind the line for the trimmer.

There are two types of bobbin. In general, they do not differ much from each other. Regardless of the type, the spool is divided into two compartments. top and bottom. The first type does not have a ring and has a recess in the separating edge.

In the second type, on the other hand, it is solid, but there are small through holes on both sides of it. The way of winding the thread should be studied depending on which of the above types the spool belongs to.

  • The previously prepared six-meter segment should be bent in half. It is best not exactly in the middle, but so that one half is longer by about fifteen centimeters.
  • Then insert the bending point into the recess in the bobbin’s separating edge. One half of the line should be on the top half of the spool and the other half on the bottom half.
  • Now you can start winding directly. Wind it in the direction of the arrow on the bobbin. When winding, hold the threads so that they do not intertwine and the upper half is wound into the upper part of the spool and the lower half is wound into the lower part. Each half has about fifteen centimeters of free space from the end.
  • There are small notches (slots) in the top edge of the bobbin to secure the consumables. The ends of the threads should be inserted into these notches so that they are secured one against the other.
  • The final stage of threading the consumable material into the tool. the ends fixed on the bobbin need to be slipped into the appropriate holes in the head of the grass trimmer.
  • That’s it. The winding process is complete. Now all that remains is to reassemble the head as a unit. The spring is carefully placed back between the bobbin and the head. Then insert the bobbin into the head and press them together.
  • It is recommended to pull the loose ends of the thread further out. To do this, take turns pulling the ends of the consumable so as to remove them from the grooves of the bobbin. Check that the cutting element is removed from the retaining grooves by pulling the threads out so that they can exit freely through the head holes.
  • Press the bobbin downward and place the cover over it. The cover should be screwed to the head so that all the grooves on their housings are aligned and the bobbin remains fixed between them.
  • And finally, the last action. the head is screwed back into place at the bottom of the tool.

Process completed. the line for the trimmer is threaded into the reel. The grass trimmer is now ready for use.

The second way of winding

  • The previously prepared section of six meters length, you need to bend exactly in the middle and cut. This makes two pieces of equal length.
  • Make a small hook at one end of each thread. To do this, bend a couple of centimeters from the edge and fix for a while so that the “hook” does not unbend.
  • Then we take a single piece. The “hook” is inserted into the through hole in the top of the bobbin.
  • Now we can proceed to the key step. winding. An arrow on the bobbin points in the direction of winding. It is important to make sure that the line for the trimmer is wound strictly within the top of the spool. You don’t have to wind it up to the end, about fifteen centimeters should be left free from the end.
  • There are small notches (called grooves) in the upper edge of the spool to fix the consumable material. You must insert the free thread “tail” into one of these notches.
  • The upper part of the spool is threaded. Now it is necessary to do the same procedure with the lower part. The second strand of thread is taken. “Hook” is put through the through hole in the bottom of the bobbin.
  • After that, you can start winding the line for the trimmer (within the lower compartment). You must also leave about fifteen centimeters of thread free from the end of the strip. This remaining “tail” must be inserted into the notch opposite to that in which the end of the first piece is inserted.

How the line head works on the brushcutter Why you need to know how it works

Depending on the manufacturer, the heads differ structurally not only externally, but also internally. Most reels have a compression spring inside (semi-automatic and automatic). Above is an instruction on how to disassemble the grass trimmer head without a spring, t.ะต. on the manual type head. The dismounting principle of the semi-automatic head with spring inside is almost identical to the above instruction.

The principle of operation of the semi-automatic grass trimmer spool is as follows:

  • Inside the head is a spool, which is planted on slits that prevent its free movement
  • The coil is actuated by a spring, which presses it against the slits in the cover structure
  • A line for the trimmer is wound on the lead, the length of which depends on the tool itself. Usually this length is 1 to 4 meters
  • During work, if it is necessary to increase the length of the line, the protruding part of the drum is pressed, by which it is disengaged from the slits. At the same time, the line for the trimmer is reeled off the drum, increasing in length
  • After releasing the desired amount of line, you should release the clamp, and continue mowing the grass

The advantage of the tool with a fishing line is that this consumable material does not require sharpening, compared to metal discs. In addition, if a stone or wood gets in the way, the line for the trimmer simply comes off, without negatively affecting the tool’s gearbox and engine, as it happens in the case of metal cutting discs.

Knowing the construction and device of the types of mowing or trimmer heads, it is necessary to proceed to consider the process of threading the fishing line into the grass trimmer spool. It’s the moment most power tool owners have trouble with.

What line to choose

In order to thread a line into your trimmer head successfully, it is important to use the right filament. The thicker the cord you tuck in, the thicker and tougher the grass it can cut. Often a universal line for trimmer is used, the diameter of which is 2 mm. You can find the right diameter for your mower in the following ways:

  • Check the instruction manual supplied with your trimmer for information on line thickness.
  • Note the bobbin itself. Sometimes it is marked with information about the possible line diameters.
  • Another option is to try to insert the cord into the outlet hole. If it passes through it without difficulty, the chosen diameter of the cord is suitable for use.

You can choose the cord according to the type of motor. If the line for the trimmer will be too thick, then the resistance to rotation will increase. the engine in this case will greatly overheat and will soon fail. Useful recommendations:

  • For an electric device with a motor under 500V, a 1.3mm cord is fine. If you do not have one, you can use 1.6 mm trimmer line. If the power is greater than 1 kW, then choose a cord diameter of 2 mm.
  • The gasoline grass trimmer has a value of the shaft mower. For the bent version a 2 mm cord is often used. If the shaft is straight, then install 2.4-2.5 or 3 mm thread. The thickest fishing line for the trimmer is installed on powerful devices. from 1.3 kW.

Pay attention to the type of cross-section of the cord. Some popular options:

  • The most common lines have a circular cross-section. They mow fresh grass well, but do not handle shrubs, dead wood as well.
  • Twisted (spiral) cord is not highly durable, but not bad for thin young grass.
  • A serrated filament with sharp edges is ideal for large weeds in a neglected area.
  • Rectangular, starred or square grass trimmer line can mow the lawn more evenly, but they are not very durable.
  • The strongest line is two-piece cord with an inner core and a circular cross section.

Note that you can’t use wire, metal strings and ropes, or ordinary fishing line instead of fishing line. The device will be dangerous for both the user and others. So the rope or similar products will gradually start to work, resulting in their ends unraveling, and the small pieces will fly away at high speed.

What you need to know about lines for grass trimmers

The line is called a consumable, which consists of nylon, and serves as a cutting device. It is used to cut the grass, which is achieved by rotating the head of the tool at high speed. This material has different thickness, which depends on its use on the respective tools electric low-power (1 to 1.6 mm), electric from 500 watts (2-2.4 mm) and gasoline grass trimmers with brushcutter (2.4 to 3.2 mm).

The more powerful the tool, the thicker the cutting attachment must be. It affects not only the quality of grass mowing, but also the service life of the material. If you’re wondering how to wind the grass trimmer reel, then it’s time to change to recharge the tool. With the advent of spring, this issue is becoming more and more in demand, so it’s time to understand the step-by-step instructions for replacing the fishing line in the grass trimmer spool.

How to remove the spool and replace the line for the trimmer

Trimmer owners, mostly beginners, get confused, bordering on panic, when there is a need to change the cutting tool or line for trimmer in the reel. Very often when trying to unscrew the mowing head, users simply cause it to fail, unaware that it unscrews in the opposite direction. To prevent this from happening if a replacement tool is needed, we recommend reading the step-by-step instructions below.

  • Before tucking the trimmer line into the reel, turn off the brushcutter engine or de-energize the electric grass trimmer to avoid injury from accidental startup of the cutting tool rotation.
  • Unscrew the nozzle attached to the reducer shaft. To do this, the shaft must be secured by aligning the holes on the washer and the axle, and inserting a metal bar or screwdriver.
