How to Change a Fishing Line On an Electric Trimmer

The trimmer is a necessary and useful tool for a summer cottage and a private house. Many own and actively use it, but not everyone knows how to replace a fishing line in a trimmer, especially at first.

In this manual, we will step by step analyze the entire replacement process. Looking ahead, there are two ways to line the trimmer spool with fishing line. There is no fundamental difference. the difference is that in the first case there will be one fishing line, folded in half, and in the second there will be two lines of such lines.


Replacement Preparation

How to Change a Fishing Line On an Electric Trimmer

Disassemble the trimmer spool

For clarity, the mowing head (spool) was removed from the lawn mowers. To replace the fishing line, you do not need to remove it, everything is done locally. It does not take much time.

We disassemble the trimmer spool. it rests on the latches-latches. Remove the cover by pressing on the latches. If you do not have enough effort with your hands, then use a screwdriver.

The spool consists of the following:

  • Spring housing
  • Locking lid
  • Button Coil

The principle of action is as follows. By pressing the button, the coil presses on the spring and exits the locking grooves in the spool cover. While holding the coil in this state, you can twist, thereby adjusting the length of the fishing line. When you release the button, the housing spring returns the coil to its original fixed state.

Disassembled Trimer Spool

Below on the coil there are several holes for different diameters of the lines. Different trimmer manufacturers may vary. In some cases (as here) they are signed, in others not.

These holes are needed to fix the fishing line when replacing it. After winding on a woman’s fishing line, the ends of the latter are inserted into them. This is necessary so that the scaffold does not unwind at the time of installation of the coil in the trimmer housing. In other words, it facilitates the replacement of fishing line.

Fishing Line Holes

There are models without specifying the diameter of the consumable. Then, in order to find out what the maximum diameter of the scaffold can be used, it is tried on through the holes for removing the fishing line from the body of the trimmer spool (see the figure below).

Fitting on fishing line outlets

The reel has two sections for fishing line, separated by a partition. They may not be. They are needed only to distinguish and facilitate winding of the consumable.

Two sections for fishing line

Initially determined with the required length of the loess. The latter is wound in one of the sections of the coil so that it does not go beyond its limits. In this case, 3 mm was wound, the length was about 2 meters. Those. for two sections you will need a 4 meter cut. this is for the 1st method. For the second method, you need two segments of 2 meters.

Determination of the required length of fishing line

Now you need to figure out which side you need to wind it. To do this, many manufacturers of trim tabs on the coils apply special designations such as in the figure below.

Special designation on the reel

If such designations were not found, then you need to pay attention to the body of the spool. There is without fail an arrow that indicates the movement of the mowing head. The line is wound in the opposite direction.

Designation on the spool housing

First way

Bent in half fishing line

The prepared segment (in this case 4 meters) is bent approximately in half. one segment should be 15-20 cm longer and inserted into a special slot located on the dividing wall.

The fishing line is inserted into the slot

In a previously defined direction, the fishing line is wound. This is done in a tight fit, the line is neatly distributed. In this case, you need to wind a segment that is longer in the section that is closer to the button.

There are designs in which the division of the coil into two sections is not provided. This does not change anything, the fishing line is wound in a similar way. It is only necessary to ensure that the segments do not overlap among themselves.

The first segment that ends at the bottom of the coil, i.e. one that is closer to the fixing holes.

This tip is placed in the corresponding diameter hole. The fishing line is firmly fixed.

The fishing line is firmly fixed

A long section is wound another half turn. There it is similarly fixed. In this case, the segment crosses another section of the coil.

A long section is wound another half turn

The fixed ends of the wound fishing line are inserted into the holes of the trimmer spool housing.

The fixed ends of the wound fishing line are inserted into the holes of the trimmer spool housing

The coil is attached to the body. The ends of the fishing line are pulled with force so that the fishing line previously fixed in the holes of the reel springs out. This is easily determined by the characteristic sound (click).

The ends of the fishing line pull

The coil with the button is latched into the body of the trimmer spool.

The coil with the button snaps into the body of the trimmer spool

Replacing the fishing line was successful. In this case, you need to install it back on the trimmer and you can start mowing the grass.

It should be repeated, you do not need to remove the spool from the trimmer. this was done to make the process of replacing the fishing line easier. You can disassemble the spool in place, wrap it on a reel and put it back.

Successfully replacing fishing line

The tips so that they do not hit the trimmer cover can and should be cut.

Method 2. two segments

Two wound lengths of fishing line

Method number 2 fundamentally no different from method number 1. The only difference is the two wound lengths of fishing line, instead of one.

The end of each segment is bent

The end of each segment is bent.

Two special locking sockets

There are two special locking sockets on the coil (see figure above).

Start winding the fishing line

They hook onto it with a hook formed earlier on the fishing line, and begin to wind the fishing line.

Winding is carried out in a special order.

The winding should be carried out in the following order: first the bottom line, i.e. the one that is closer to the fixing holes at the bottom of the coil, and only then the upper one, i.e. the one that will overlap the bottom section.

The bottom line is wound

The tips are made into the holes in the body of the trimmer spool. They are pulled up to a click, which indicates that the line has come out of the clips.

The tips are threaded into the holes of the trimmer spool housing

The coil is fastened into the housing. The fishing line in the spool is replaced.

Replacing the fishing line in the trimmer: 2 easy ways

Feedback from our readers is very important to us. Leave your rating in the comments with the reasoning of your choice. Your opinion will be useful to other users.

Guaranteed production of a factory trimmer refill will inevitably require replacing the fishing line. Having a very rough idea of ​​how to fill the fishing line into the reel of the trimmer yourself, beginners are reluctant to take up this matter. However, with some skills, mastering this simple science does not present any difficulties, and the similar instruction presented below will facilitate this process as much as possible.

Preliminary preparation

First of all, for winding fishing line it is required to remove the reel (bobbin, spool) from the trimmer. specific actions will depend on the complexity of the configuration and the type of product itself:

  • Small electric trimmers with a working arrangement of the engine and the coil in the lower part, as a rule, have side keys on both sides of the bobbin. By pressing them simultaneously, the upper part of the reel, together with the internal contents for winding the fishing line, is disconnected, while the lower one remains on the trimmer. It is advisable to disassemble the bobbin on an even smooth place so that the spring included in the design does not pop out and is not lost;
  • electric and gasoline trimmers with a curved rod without the possibility of installing a knife, as a rule, have coils with a special wing: in such designs, you should hold the spool in one position with one hand and rotate the locking reel on the wing nut with the other counterclockwise. After disconnecting the nut, the entire reel is removed.
  • electric and petrol trimmers with the possibility of installing the knife on a straight bar (for example, Stihl trimmers) have a hole under the bobbin. For the motion of the rod to be stationary, a screwdriver or other suitable object is inserted into this hole and during slow rotation, such a mutual arrangement is achieved when the screwdriver enters the hole and the bobbin is fixed. After that, the coil body scrolls clockwise (with the left thread) and is removed from the trimmer.

For the second and third cases, the coils, depending on the design, are disassembled in various ways. In bobbins with a lamb, a lamb is twisted, in coils with latches, latches-clamps are pressed and one part of the coil is released from the other. If the halves of the spool are threaded, it is enough to turn them by hand in opposite directions until completely unscrewed.

We carry out winding fishing line

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

Coil with one working antenna

The simplest option and a simple sequence of actions:

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

Coil with two working antennae

In this type of spools, you should determine the number of grooves for winding fishing line lying on the inside of the reel:

  • one groove. both antennae are wound together along one groove;
  • two grooves. each antennae is wound on an individual groove.

In both cases, a 2-3-meter-long fishing line is taken. In single-groove reels, the fishing line is pulled into the through hole, its ends (antennae) are folded together and aligned, after which they are wound in the opposite direction of rotation of the bobbin on the side of the bar. the correct direction of winding is usually indicated inside the arrow. In the presence of fixing grooves, the ends of the fishing line are threaded into them or held by the fingers of their free hands, threaded into the through hole of the outer half of the bobbin, the spool is closed and attached to the bar of the trimmer.

The difference between winding fishing line in two-groove reels is that initially a piece of fishing line 2-5 m long is folded in half (to determine the middle bend), and the bend loop is inserted into a special groove between the grooves. Both antennae of the fishing line are wound each in its own groove, the fixation of the antennae and the reel assembly is similar to the one-groove variant discussed above.

The first implementation of this procedure may seem long and rather laborious, but with time and experience this task will be solved much faster and easier.

The video below will clearly show how to put the fishing line into the coil of the trimmer and wrap it correctly. this operation is not complicated and with some patience will surely succeed:

Automatic reeling of fishing line

There is a variety of coils in which the automatic mechanism coils on its own. from the user it is enough just to properly fill the line. The fishing line is passed through the hole on the inside of the case, its antennae without winding is passed through the hole on the external case, the bobbin is assembled, and when the winding button is rotated, the line inside is wound up independently. In such a spool, it is impossible to make the winding incorrectly: the mechanism itself will determine the correct direction, since it can only turn in one direction.

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

What is needed to replace the cord

When the trimmer is used regularly for grass mowing, the discs become dull, but they can be sharpened and continued to be used. The fishing line in the reel tends to end, so there is a need to refuel a new one, for which you need to determine the type of head and prepare a cord of the required thickness and length.

So, the mowing head is a cylindrical body in which a bobbin with fishing line is placed. Such a detail is present both on trimmers and on gasoline braids of any brands, be it Bosch, Makita, Stihl or another brand. The heads are of three types, depending on the method of refueling and feeding the fishing line.

  1. The principle of operation of the heads auto group consists in the fact that they independently feed the fishing line when the mower reduces the engine speed. Such designs are convenient when working on large areas, but have the disadvantage of high cord consumption.
  2. Heads semi-automatic group easy to operate. automatic line feeding is performed at maximum engine speeds. To release the cord lock, gently tap the tool on the ground, after which the unlocked thread extends from the spool. Cutting to the required length is carried out with a knife mounted on a protective casing.
  3. Trimmers with manual feed the cord must first be turned off, and then pull out the fishing line yourself.

On a note! The most convenient and best priced are semi-automatic cord reels.

Coils for electric and gasoline braids can be with one or two antennae fishing line. The former are used to trim low grass overgrowth, and the latter are used to trim tall grass and small bushes.

Preparation for replacing fishing line

Before replacing the fishing line, you need to pull out and then disassemble the head. Usually it includes a casing, a spring (on some models), a bobbin with fishing line, a cover. It is necessary to disconnect the electric trimmer from the network (or muffle the gasoline), 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 mounted.

  • find the latches on both sides, press and remove the cover to open the internal device of the head;
  • there is a bobbin under the cover, it must be carefully removed from the case (sometimes a spring hides under it, it should also be carefully removed to the side so as not to lose);
  • after removing the spool, a fixing bolt (or screw) becomes visible in the center of the housing, which must be unscrewed in the opposite direction to the clockwise movement;
  • after removing the fasteners, hold the housing by swinging movements to remove the coil from the gearbox shaft.

Second way involves the following actions. The coil head is mounted on the gearbox shaft. To disconnect it, it is necessary to lock this shaft. Usually in braids, for example, of the Champion or Stihl brand, a hole is made for this, into which a nail, a rod or a screwdriver is inserted. After fixing the shaft in a fixed position, holding the housing, it is necessary to start turning the head clockwise, since the thread on the shaft is usually applied left.

Now that the head is removed and disassembled, it is necessary to determine how thick the cord should be. You can find out the suitable diameter for your trimmer by looking in the user manual or on the bobbin itself, usually similar information is indicated on it. Another way is to insert the thread into the hole from which it is fed. If the scrum goes without difficulty, it can be used for work.

On a note! To understand how much fishing line to reel for the reel, you need to wind it on a bobbin so that the height of the reel is not greater than the diameter of the sides. If the cord protrudes beyond the edges, the coil cannot be hidden in the casing.

Line winding algorithm

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

To the coil with one antennae

It is very easy to wind a fishing line onto a reel with one antennae. In such designs, depending on the brand of trimmer, two to five meters of cord is placed. The edge of the fishing line in the spool must be tucked into a special hole or groove, after which the string is wound in the direction opposite to the rotation of the coil during operation.

Advice! To understand which way to wind the thread, you should look at the bobbin case. usually marks are made on it that indicate the direction of movement of the bobbin during operation.

After the fishing line is wound, you need to leave a small piece (15-30 cm), thread it into the exit hole of the spool and reassemble the head.

To the coil with two antennae

In spools 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.

Important! If there is one chute in the coil, then both antennae must be wound along a common groove, if two, then on separate tracks.

For winding, you need to take a piece of fishing line with a length of two to three meters. For single groove spools it is necessary to fill the line into the through hole, align the mustache, align and wind it on the reel in the direction opposite to its rotation during operation. If locking grooves are provided, they need to thread the ends of the cord, then pull them into the outlet, then close the coil and put it back on its place.

For two-groove spools the difference is that the length of the string should be folded in half. Next, you need to charge the middle of the bend into the groove between the grooves, then wrap each of the pieces of fishing line along its path, fix the antennae and assemble the reel as well as the spool with one path.

On trimmer head with automatic refueling

For heads with automatic refueling, just enough start and pinch the edges of the line, and the tool will carry out further winding on its own when turned on. It is impossible to make a mistake here, because the coil itself recognizes how the antennae should be located.

On a note! The advantages of trimmers with such a head include the convenience of laying the cord, and the disadvantages are the high cost and complicated repair.

Fishing line. varieties and the possibility of replacing with other material

The cord for the trimmer 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 fishing line, the more rough grass it can handle. Experienced users recommend putting a fishing line with a thickness of 2 mm, which is universal.

Fishing line shape can be round (for juicy grass) or with sharp edges in the form of a square or asterisk (for mowing dry grass). The second type is less durable and wears out faster than a 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, for example, metal or steel cables and strings, wire, etc. You need to know that the installation of such items 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 apart in different directions, risking injury to the worker. And if you accidentally touch their limbs during work, a serious injury is guaranteed.

For trimmers who are interested in using fishing line, we answer. this is allowed, but it will tear and wear much faster, which means that it will require frequent replacement.

Advice! Fishing line is well suited for harvesting grass near a fence or wire mesh. instead of spending an expensive trimmer cord, you can charge large-caliber gear (2-3 mm), which is much cheaper.

Replacing fishing line on the disc

Depending on the type of vegetation covering the garden (lawn) and requiring removal, the fishing line changes to disk. This is necessary, since the cord is used only for grass of small height, and if you need to mow tall growth, shoots of trees or shrubs, instead of a string it is better to use metal or plastic knife-disks. Installing them correctly is very simple, the detailed process is usually described in the user manual and is similar for trimmers of different brands, be it Al-Co, Oleo-Mac, Patriot or another brand of equipment. To change fishing line to knives, you must:

  • lock the shaft and remove the coil by turning it clockwise;
  • put the knife on the sleeve;
  • install the locking cover and in a counterclockwise direction tighten the nut, and then tighten it with a wrench.

You can read in detail how to change the reel with fishing line to disk in the device’s instruction manual.

Solving possible fishing line problems

Most of the problems associated with fishing line, similar for different trimmers and are solved in a similar way.

String break

Regular line breaks are caused by:

  • the presence in the mowing grass of solid objects: branches, stones, etc., contact with which breaks the string;
  • mowing the grass is close to the fence, and if it is mesh, the fishing line breaks even faster;
  • low-quality cord. a replacement for a new reliable consumable is necessary;
  • wear of the outlet openings in the mowing head, as a result of which the fishing line breaks off from friction against the sharp edges of the bushings. replacement of the part with a new one is required.

High consumption of fishing line

Typically, the fishing line ends very quickly if you constantly tap the semi-automatic reel on the ground or press it firmly to the surface. In this case, the head unlocks, the cord lengthens, and the knife cuts it. The second option is the fast consumption of fishing line. a trimmer with an automatic reel is not used correctly. If the mower regularly reduces the engine speed, the string is constantly lengthened and cut, and as a result is quickly consumed.

The string does not hold

If the coil is semi-automatic type the spring is weakening, the fishing line does not hold and unwinds during operation. The cord extends, is cut with a knife, as a result, the owner of the equipment notices that the thread ends quickly.

Advice! To test the tool, you need to remove the protective cover and start the engine. if the fishing line extends, this means that the spring must be replaced with a new one.

Fishing line crashes

If the string flies when mowing, this is another evidence that the spring in the bobbin is weakened or completely lost when the head was not properly dismantled. As a result, the cord does not hold and jumps out during rotation.

The string does not extend

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

  • the fishing 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. to prevent this from happening, you need to wind the thread carefully, avoiding distortions, turn to the turn;
  • the ends of the cord coming out of the holes are very short, centrifugal force is not enough to remove them, so the fishing line is not fed. before turning on the trimmer, it is important to adjust the length of the thread and lengthen it a little, if necessary;
  • the cord stuck together.

The coil does not spin

The reasons why the reel does not spin are similar to the lack of line feed. This is an incorrect or uneven winding of the string, its sticking, as well as the short ends of the cord coming out of the holes.

Fishing line sticks together

If the fishing 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, its sharp braking occurs, the thread is pulled into the head and sticks.

Advice! To avoid problems, you can apply mineral oil to the surface of the fishing line or, after winding on the head, spray it with silicone. A more competent solution will be the acquisition of a good quality head, which will forget about such problems.

So, replacing the fishing line on the trimmer is not difficult if you know how to disassemble the coil and wind the cord. This process is similar for technology of different brands. A detailed description can be found in the instruction manual of the tool or watch the video.
