Instruction: replacing the trimmer line

The above explains (using the example of the design of an electric and gasoline lawn mower) how to replace the line in the trimmer. The use of different types of cutting material for cutting grass is noted. The complete process of changing the cutting material in each section of the winding drum is clearly demonstrated.

Step two: remove the winding drum (spool) with line

The next step in the process is the removal of the winding drum with line from the inside of the head. You need to return the head with the open side to see the line and spool. On the side of the head, find two recesses (eyes) through which the fishing line is brought out.

It is necessary to free the fishing line from the holes turned the drum. Then carefully remove the coil from the head area. Winding drum Some models are spring-mounted. This point must be taken into account when performing the extraction operation.

How To Change Line On A Trimmer

The procedure for removing the trimmer spool with line from the inside of the head: 1. head assembly with spool; 2. extraction carefully with small axial rotation; 3. extracted parts

The old line is completely removed from the reel. To remove the old trimmer line, you need to remove the forest from the locking loops and pull the free end. This method removes all the old winding. The same process is repeated on the second section of the drum. The master is recommended to use gloves when performing work.

Changing the trimmer line: Step-by-step instructions for replacing the line with a trimmer

Trimmers (they are also lawn mowers) are actively used by modern society to care for lawns and other similar objects of horticultural farms. The tool is noted for high efficiency, despite the questionable quality of cutting grass (in comparison with the usual peasant scythe. earth and sky). The main advantage of trimmers (lawn mowers) is high productivity with low expenditure of physical forces of the operator. However, over time, the trimmer’s cutting element (nylon scaffold) wears out or gets damaged, making the trimmer a useless tool as a result. Hence, the task becomes urgent. how to replace the trimmer head and how to replace the trimmer head line? Let’s consider this process using the example of lawn mowers manufactured by “Black and Decker” and others.

Installing new line on the trimmer reel

Equipping the reel with a new line is carried out in the reverse order. The procedure looks something like the following, regardless of the lawnmower model:

Step two: winding the cutting material along the section

The next step is to wrap the line around the reel, being careful. It is necessary that each half be filled with “own” winding, exactly, without Peresechen. Usually, arrows can be seen on the body of the winding reel indicating the direction of winding. This point should be borne in mind, Fill the spool with fishing line.

How to replace the line with a trimmer?

Replacing the trimmer line Step-by-step instructions will allow even an inexperienced lawn mower owner to perform a rather difficult job.

However, before starting work on replacing the line with a trimmer, it is necessary to ensure the safety of the work. In particular, measures should be taken to prevent unintentional or unintentional starting of the lawnmower:

  • Eliminate Spontaneous Startup,
  • Remove battery (if applicable),
  • Place the tool on a platform convenient for work.

It is convenient to work on replacing the trimmer line when the mower is lying on the table, and the foreman, who replaces the trimmer line, has the opportunity to approach the tool from either side.

Step three: complete the head assembly

Pull the ends of the line through a pair of oval slotted spool. Replace both washers and the spring (if any in the structure) supplied with new elements. Bend both ends of the line at right angles.

The final technical touch of the process of replacing the line with a trimmer is the imposition of the cap on the head, followed by fixation by means of pushing force and slight twisting.

Pass each end into the hole in the base of the winding drum. Install the coil in the inner area of ​​the head, resting on the spring. Place the lid on, align with the base and lightly push down with a small counterclockwise rotation, fit the lid on the tabs of the latches. This completes the replacement procedure.

Step one: securing and laying

Fold the end of the line in half. Place a blank over the spool on each side of each half of the winding zone. Draw both halves all the way around the winding drum. Pull the line through the loop.

The procedure for preparing the line engagement in the area of ​​both winding sections of the drum. The loops are placed in specially made cutouts, after which the line is wound in each zone

Pull the line tight enough to fit the knot into the groove made on each side of the winding drum.

Removing the trimmer head cover

At the first stage of disassembly, the trimmer head cover is removed. On the example of Black and Decker trimmer models and others, to remove the cover, it is usually enough to apply some pressure in order to squeeze the locking latches, which are located on the side of the head body.

On some mower models, the trimmer head is initially dismantled using the Allen key supplied with the tool. The head is usually held in place by two to three screws, which are accessed through the side holes of the rear bezel.

The head cover, where the line spool is installed, is usually held by a latch-tongue. It is enough to squeeze the latch tab with some effort and turn the cover slightly, after which the cover can be easily removed

At the moment of pressing the locking tab, you need to slightly return and lift the trimmer head cover to remove the winding drum.

How to wind the line onto the trimmer spool

The trimmer is a great solution for those who have a large garden or lawn near the house, which 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 cutter, you must first select it correctly. In principle, the lawn mower instruction manual 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 on the Internet. Which will help you figure out how to properly thread the line into the trimmer spool.

How to change line to trimmer

Below we have provided Step-by-step instructions for replacing a whine trimmer.

The first thing to do is unplug the tool and turn off the engine. Then you need to remove the trimmer head. This can be done by using a simple screwdriver, lowered 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 be necessary to twist 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, which are located opposite each other. Pressing on them, you can remove the head cover, and then pull out the spool on which the fishing line is wound. By pulling it out, you can determine what type it belongs to. There are bobbins one-piece and two-piece

We analyze how to thread the line into the trimmer spool in two versions

So, option one. load the fishing 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 the winding, do not forget to check that the different ends of the thread are looking in different directions.

READ  Wrap Fishing Line On Trimmer Coil

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

Winding is carried out, as in the first case, along the arrow indicated on the spool. Both segments must be wound so that they do NOT overlap. Further, the ends of the thread must be fixed in the grooves and spread on opposite sides.

The spring is then inserted into the reel and the whole thing is placed in the mowing head. When placing the coil in the trimmer you need to gently hold the spring parallel to insert the line into the cut of 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 look at how to install the line on the reel in the trimmers.

How to remove the line from the trimmer spool

Over time, the cutting element of the head wears out, and it becomes necessary to pull out the remnants of the old line. But not everyone knows how to do it. Our step-by-step instructions plus how to pull the thread from the trimmer spool, which you can find on the net, will help in solving this issue.

The mowing head must be disassembled

Remove the cover using the clips

Cleaning up the remnants of cutting material

Complicated? Of course not. But if, nevertheless, doubts creep into you that for some reason you will NOT be able to do this, then of course find and see how to pull out or how to wind the thread onto the spool of the lawn mowers.

How to replace the line with 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 gasoline scythe, you get more freedom, since it is NOT limited by the cable, which is present on the electric scythe

Yes, do not hesitate to use special rollers for installing or threading the line in an electric scythe, which can teach you much faster than simple reading.

What types of woods are there

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

As a rule, the diameter, which can mow young grass, and 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 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 tear and it 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 it is used only for lawn mowers, since the exit of such a thread from the reel is difficult, it is used most often with discs in which the segments are inserted. The disadvantage of such a product is its fragility.

Most often in gasoline trimmers with an engine power 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 to the trimmer and which one is better to choose

Since we considered the choice of a trimmer in a previous article, today we will tell you how to properly fill the trimmer with a 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 out element in the tool, intensive use of the trimmer will lead to frequent replacement of consumables.

How to remove or tuck the line into the trimmer

In order to wind the line, it will take about 10-15 minutes. What is a trimmer coil? Plastic body with a cassette inside, on which there is 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 stretch 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 in the ground itself, have a different attachment to the axis of rotation, they have two buttons on the coil on the sides, which must be wrung out, otherwise the whine replacement is not 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 tendrils.

To remove the spool with the fishing line, it is necessary to Unscrew, located in the center, the screw, but Note that the thread is left there, so it will have to be turned 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 fishing line into the spool.We bring out, in total, 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.

If in doubt or it is not entirely clear how to load the line on the trimmer, we recommend that you look at: how to properly wind the line into the lawn mower.

In this, step by step, the instructor will open the trimmer head, measure the required amount of line, usually from two to four meters, and demonstrate assembly and installation on the trimmer.

String DOES NOT extend

In automatic and semi-automatic reels, the cord is fed without stopping the trimmer. If this does not happen, then:

  • The line in the head is not wound correctly, so the reel does NOT spin;
  • The winding of the fishing line is uneven, so the cord gets stuck between the turns and does NOT come out. so that this does not happen, you need to wind the thread carefully, do not allow distortions, turn to turn;
  • The ends of the cord coming out of the holes are very short, centrifugal force is not enough to pull them out, so the line is NOT fed. before turning on the trimmer, it is imperative to adjust the length of the thread and lengthen it a little, if necessary;
  • Cord stuck together.

The line is sticking

If the line sticks together during operation, the main reason is the installation of a low-quality cord. During operation, the coil heats up, and a poor-quality string melts and sticks together. The second reason is the collision of the cord with solid objects. In this case, it is sharply decelerated, the thread is pulled into the head and sticks.

So, replacing the line with a trimmer is NOT difficult if you know how to disassemble the reel and wind the cord. This process is similar for different brands of appliances. A detailed description can be found in the instruction manual of the tool or look at.

How to properly change the line to a trimmer

The trimmer is a handy and easy-to-use tool for cutting grass and trimming small shrubs and trees. As a cutting element, it often uses a fishing line (string, cord), because it costs less than disc knives and is safer to use. With intensive use of the tool, over time, you will need to change the line to a trimmer. The process is similar for mowers from different manufacturers, be it Husqvarna or Huter, with possible minor differences.

The string does NOT hold

If the spring looses in a semi-automatic reel, the line will NOT hold and unwind during operation. The cord is pulled out, cut off with a knife, as a result, the owner of the technique notices that the thread is quickly running out.

Preparing to replace the line

Before replacing the line, you need to pull out and then disassemble the head. It usually includes a cover, a spring (on some models), a bobbin with line, and a cover. It is necessary to disconnect the electric trimmer from the mains (or turn off the gasoline trimmer), and then proceed to remove the coil. It can be fixed in two different ways: in the first case, it is necessary to completely disassemble the head, and in the second. just remove it from the gearbox shaft, on which it is attached.

  • Find the clips on both sides, press and remove the cover to open the internal structure of the head;
  • There is a bobbin under the cover, it must be carefully pulled out of the case (sometimes a spring is hidden under it, it should also be carefully removed to the side so as not to lose it)
  • After removing the spool, a fixing bolt (or screw) becomes visible in the center of the body, which must be unscrewed in the opposite direction to the clockwise movement;
  • After removing the fasteners, it is necessary to remove the coil from the gearbox shaft, holding by the body, with shaking movements.

The second method involves the following actions. The spool head is put on the gearbox shaft. To disconnect it, you need to lock this shaft. Usually, a hole is made in hair, for example, the Champion or Stihl brand, into which a nail, rod or screwdriver is inserted. After fixing the shaft in a stationary position, it is necessary, holding by the body, to start turning the head clockwise, since the thread on the shaft is usually left.

Now that the head has been removed and disassembled, it is necessary to determine how thick the cord should be. You can find out the correct diameter for your trimmer by looking at the owner’s manual or at the bobbin itself, usually this information is indicated on it. Another way is to insert the thread into the hole from which it is fed. If the shit goes without difficulty, it can be used for work.

On a reel with two tendrils

In bobbins of this type, you need to inspect the inside of the coil and determine the number of grooves for winding the cord provided in it.

For winding, you need to take a piece of fishing line from two to three meters long. For spools with one groove, thread the line through the hole, align the mustache, align and wind it around the spool in the opposite direction of rotation during operation. If fixing grooves are provided, thread the ends of the cord through them, then pull them out into the outlet, then close the coil and put it back on.

For double-groove spools, the difference is that the string must be folded in half. Next, you need to charge the middle of the fold into the groove between the grooves, then wind each of the pieces of fishing line along its own path, fix the antennae and assemble the coil in the same way as a spool with one track.

The coil does NOT spin

The reasons the reel does NOT spin are similar to the lack of line feed. This is improper or uneven winding of the string, its sticking, and also short ends of the cord coming out of the holes.

Fishing line. varieties and the possibility of replacement with a second material

The trimmer cord can be of different diameters (from 1.2 to 4 mm), and you need to choose it depending on what kind of vegetation you want to mow. the thicker the line, the coarser the grass it will cope with. Experienced users recommend using a 2 mm line, which is universal.

The shape of the line can be round (for juicy grass) or with sharp edges in the form of a square or an asterisk (for beveling dry grass). The second type is less durable and wears out faster than round cord.

One of the popular questions regarding the operation of trimmers is whether it is possible to replace the special cord for mowers with other materials, such as metal or steel cables and strings, wire, etc. You need to know that the installation of such items is not recommended, because with them the trimmer turns into a dangerous technique. During the mowing, pieces of wire or metal will constantly break off and fly in different directions, risking injury to the worker. And if they accidentally touch their limbs during work, a serious injury is guaranteed.

For trimmer owners who are interested in whether fishing line can be used, we answer. this is allowed, but it will tear and wear out much faster, which means that it will require frequent replacement.

High line consumption

Usually the line ends very quickly, if you constantly knock the semi-automatic reel on the ground or with the force of pressing it to the surface. In this case, the head is unlocked, the cord lengthens, and the knife cuts it off. The second option for fast line consumption. the trimmer with automatic reel is not used correctly. If the mower regularly lowers the engine speed, the string is constantly lengthened and cut and, as a result, is quickly consumed.

Changing the line to a disc

Depending on the type of vegetation covering the garden area (lawn) and requiring removal, the line changes to a disc. This is necessary, since the cord is used only for grass of a small height, and if it is necessary to mow High growth, tree shoots or bushes, instead of a string it is better to use metal or plastic knives-discs. It is very easy to install them correctly, the detailed process is usually described in the owner’s manual and is similar for trimmers of different brands, be it Al-Co, Oleo-Mac, “Patriot” or second brand appliances. To change the line to knives you need:

  • Block the shaft and remove the coil by turning it clockwise;
  • Put the knife on the sleeve;
  • Install the retaining cap and tighten the nut in a counterclockwise direction, then tighten it with a wrench.

You can read in detail how to change a reel of line to a disc in the instruction manual of the device.

Line winding algorithm

The order of winding the line depends on the type of reel. with one or two Tendrils, as well as with automatic cord charging.

The coil does NOT spin

The reasons the reel does NOT spin are similar to the lack of line feed. This is improper or uneven winding of the string, its sticking, and also short ends of the cord coming out of the holes.

What is needed to replace the cord

With regular use of the grass trimmer, the discs become dull, but they can be sharpened and continued to operate. The line in the reel tends to end, so it becomes necessary to refuel a new one, for which you need to determine the type of head and prepare the cord of the required thickness and length.

So, the mowing head is a cylindrical body in which a bobbin with a fishing line is placed. This detail is present both on trimmers and on petrol hair of any brand, be it Bosch, Makita, Stihl or another brand. There are three types of heads depending on the method of threading and feeding the line.

  • The principle of operation of the heads of the automatic group is that they independently feed the line when the mower reduces the engine speed. Such designs are convenient when working on large areas, but have a drawback. high cord consumption.
  • Semi-automatic group heads are easy to operate. automatic line feed is performed at maximum engine speed. To release the cord blockage, gently tap the ground with the tool, and the unlocked thread will then be pulled out of the spool. Cutting to the required length is made with a knife attached to the protective cover.
  • Trimmers with manual cord feed must first be turned off, then pull out the line yourself.

Reels for electric and gasoline braids can be with one or two tendrils. The former are used for trimming low grass growth, the latter for mowing tall grass and small shrubs.

The line is flying out

If the string flies out during mowing, this is another indication that the spring in the bobbin has weakened or completely lost during careless disassembly of the head. As a result, the cord does NOT hold and pops out when rotating.

We wind the fishing line

Slowly completed disassembly of the spool-spool without losing its spare parts allows you to proceed to the main task. winding the fishing line into the reel. Technological features of the spool design and the number of working antennae determine the sequence of actions.

How to insert line into the trimmer spool? Instructions

The warranty production of the factory trimmer refueling will inevitably require line replacement. Having a very rough idea of ​​how to thread the line into the trimmer reel on their own, beginners are reluctant to take up this business. However, with some skills, mastering this simple teaching does not present any difficulties, and the similar instruction presented below will make this process as easy as possible.

Removing and disassembling the coil

The mowing trimmer head consists of a cover, a spring (not available in every model), a spool with a cord, a cover. Before proceeding to disassemble the coil of the electrical unit, be sure to disconnect the trimmer from the mains. The disassembly method depends on the attachment of the mowing head. First option:

  • To remove the cover that covers the inside of the head, press on the latches (latches) that are located on both sides of the head.
  • Remove the cover, under which you will see the spool. Remove it from the body. Some trimmer spools have a spring under the bobbin, which must also be carefully pulled out.
  • Soaked in the bobbin, you will see a screw in the center of the case. Unscrew it with a screwdriver.
  • After removing the fasteners, take the body of the part and, swing it in different directions, remove the gearbox from the shaft.

In the second version, the trimmer head is screwed onto the gearbox shaft. To remove it, you need to fix the shaft. For this, such devices have a hole through which a thin screwdriver or metal rod is inserted. Brief instruction:

  • Insert a screwdriver into the special hole, then lock the shaft.
  • Grasp the body of the head and start twisting it. This should be done clockwise, because the thread on the shaft is left.

Winding the line to the reel

Second winding method

  • A previously prepared segment of six meters in length is required to bend exactly in the middle and cut. Thus, two segments of the same length are obtained.
  • Make a small “hook” at one end of each line. To do this, it is necessary to bend a couple of centimeters from the edge and fix it for a short time so that the “hook” did not unbend.
  • Then one segment is taken. The hook is inserted into the through hole at the top of the bobbin.
  • Now you can proceed to the key stage. winding. The direction in which to wind is indicated by an arrow pointing to the bobbin. It is important to make sure that the line is wound strictly within the upper part of the reel. It is not necessary to wind the thread to the very tip. that’s the end About fifteen centimeters should remain free.
  • In the upper edge of the spool there are small recesses (so-called grooves) for fixing consumables. The free “tail” whine must be inserted into one of THESE recesses.
  • The top of the coil is loaded. Now you need to do the same procedure with the bottom. Take the second piece of thread. The “hook” is threaded through the through hole at the bottom of the bobbin.
  • After that, you can start winding the line (within the lower compartment). And for this segment, you also need to leave about fifteen centimeters free from the end. This remaining “tail” must be inserted into the grooves opposite to the one into which the end of the first segment is inserted.

The subsequent actions for this type of coils are exactly the same as those described for the previous type in paragraphs five to nine.

This is how the line in the trimmer spool changes. Nothing complicated in the commenting process. And already after several refuelings, all actions will reach automaticity.

To visually study the process described above, you can turn to the Internet for help. On the popular YouTube portal there are many different ones with a demonstration of winding a line on a trimmer reel.

Line selection

In order for the threading of the line into the trimmer head to be successful, it is important NOT to select the consumables. The thicker the cord you tuck in, the thicker and tougher the grass it can cut. Often a universal line is used, the diameter of which is 2 mm. You can choose a diameter suitable for the mower in the following ways:

  • Refer to the instructions that came with the trimmers for line thickness information.
  • Pay attention to the bobbin itself. Sometimes information about the possible diameters of the fishing line is applied on it.
  • Another option is to try inserting a cord into the exit hole. If it easily goes through it, then the selected line diameter is suitable for use.

Trimmer reel

You can select the cord thread by the type of engine. If the line is too thick, the rotation resistance will increase. in this case the engine will overheat and will soon fail. Helpful hints:

  • For an electrical device with a motor less than 500 V, a 1.3 mm thread is suitable. If one is not found, then you can use a 1.6 mm line. If the power is more than 1 kW, then select a cord with a diameter of 2 mm.
  • In a gasoline trimmer, the mower shaft matters. For the folded version, a 2 mm cord is often used. If the shaft is straight, then install the thread 2.4-2.5 or 3 mm. The thickest line is installed on powerful devices. from 1.3 kW.

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

  • The most common lines are round. They mow fresh grasses well, but they cope worse with shrubs, dead wood.
  • Twisted (spiral) cord is NOT very strong, but is good for thin young grass.
  • Serrated thread with sharp edges ideal for large weeds in neglected areas.
  • You can mow the lawn more evenly with rectangular, star or square trimmer lines, but they are not very durable.
  • Strongest. two-piece inner-core round cord.

Types of trimmer line

Please note that you cannot use wire, metal strings and cables, as well as ordinary fishing thread instead of fishing line. The device will be dangerous to both the user and others. So the cable or similar products will gradually begin to work, as a result, their ends will unravel, and small pieces will scatter at high speed.

Coil with one working tendril

The simplest option and uncomplicated sequence of actions:

  • The dimensions of the reel and the length of the original factory winding determine the recommended length of the line for winding. 2. 5 m.
  • One end of the line is inserted into the fixing technological hole located inside the spool.
  • The fishing line is wound on the drum in the reverse rotation of the spool in the direction of the trimmer. as a rule, on the inside of the bobbin an arrow indicates in which direction the winding is being carried out.
  • A small section of the fishing line is left free to lead it out. it is fixed in a specialized groove on the inside of the bobbin, designed to hold the winding when assembling the bobbin into working condition.
  • The left end of the line is passed through the hole in the outer part of the reel.
  • The bobbin halves are assembled and put on the trimmer bar.
