EGO 56-VOLT 15″ String Trimmer. How To Replace Cutting Line.

There are two special fixing sockets on the coil (see picture above).

We start winding the line

They hook 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 must be carried out in the following order: first the lower line, i.e. the one that is closer to the fixing holes at the bottom of the coil, and only then the top one, i.e. the one that will overlap the bottom section.

The bottom line is reeling

The tips are cut into the holes in the trimmer spool body. They are pulled up until they click, which means that the line has come out of the latches.

The tips are threaded into the holes in the trimmer spool body

The coil is fastened into the body. The line in the spool has been replaced.

The line in the spool has been replaced

The first way

Line bent in half

The prepared segment (in this case, it is 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 partition.

The line is inserted into the slot

The line is wound in the direction determined earlier. This is done in an interference 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 that do not provide for dividing the coil into two sections. This does not change anything, the line is wound in a similar way. You just need to make sure that the segments do not overlap with each other.

The first should end that section, which is located at the bottom of the coil, i.e. the one closest to the fixing holes.

This tip fits into the corresponding hole in diameter. The line is securely fixed.

The line is securely fixed

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

The fixed ends of the coiled line are inserted into the holes in the trimmer spool body.

The coil is attached to the body. The ends of the fishing line are pulled with effort so that the fishing lines previously fixed in the holes of the reel jump out from there. It is easily identified by the characteristic sound (click).

The line was changed successfully. In this case, you need to put it back on the trimmer and you can start mowing the grass.

It should be repeated, there is no need to remove the spool from the trimmer. this was done for clarity of the process of replacing the fishing line. You can disassemble the spool in place, wind it on the spool and put it back.

Tips so that they do not hit the trimmer cover can and should be trimmed.

Changing the line in the trimmer: 2 easy ways

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

In this manual, we’ll walk through the entire replacement process step by step. Looking ahead, there are two ways to line the trimmer spool. There is no fundamental difference. the difference lies in the fact that in the first case one line will be refueled, folded in half, and in the second there will be two such lines.

Preparing for replacement

We disassemble the trimmer spool

For clarity, the mowing head (spool) was removed from the lawn mower. To replace the fishing line, you do not need to remove it, everything is done locally. It doesn’t take long.

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

The spool consists of the following:

  • Spring case
  • Cover with locking latches
  • Button coil

The principle of operation is as follows. By pressing the button, the spool presses on the spring and comes out of the locking grooves in the spool cap. Holding in this state, the reel can be twisted, thereby adjusting the length of the line. When the button is released, the body spring returns the coil to its original fixed state.

Disassembled trimmer spool

On the bottom of the reel there are several holes for different diameters of the lines. They may differ from trimmer manufacturer. In some cases (like here) they are signed, in others they are not.

These holes are needed to fix the line when replacing it. After winding the fishing line on the bobbin, the ends of the latter are inserted into them. This is necessary so that the scaffold does not unwind when the coil is installed in the trimmer body. In other words, it makes it easier to change the line.

Holes for fixing the line

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 along the holes for removing the fishing line from the trimmer spool body (see figure below).

Fitting on the holes of the line output

The reel has two line sections separated by a baffle. They may not exist. They are needed only to delimit and facilitate the winding of the consumable.

Two sections for fishing line

First, they are determined with the required length of the loess. The latter is wound into 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 turned out to be about 2 meters. Those. for two sections you need a 4-meter segment. this is for the 1st method. For the second method, you need two segments of 2 meters each.

Determining the required line length

Now you need to figure out which way you need to wind it. To do this, many trimmer manufacturers apply special designations to the spools, such as in the figure below.

Special designation on the reel

If no such designations were found, then you need to pay attention to the spool body. There is necessarily an arrow that indicates the movement of the mowing head. The line is wound in the opposite direction.

Replacing the trimmer line: step-by-step instructions for replacing the trimmer line

Trimmers (they are also lawn mowers) are actively used by modern society for the care of lawns and other similar objects of horticultural farms. The tool is noted for its high efficiency, despite the questionable quality of cutting grass (compared to 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.

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. Wrap both halves completely 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

It is enough to pull the line tightly and put the knot in the groove made on each side of the winding drum.

Step three: complete the head assembly

Pull out the ends of the line through a pair of oval spool slots. Replace both washers and spring (if any) with the supplied new parts. Bend both ends of the line at right angles.

The final technical touch of the process of changing the line on the trimmer is the imposition of the cap on the head, followed by fixation by pressing force and slight twisting.

Pass each end into the hole at the base of the winding drum. Install the coil in the inner area of ​​the head, resting on the spring. Put on the cover, align with the base and lightly press downwards with a small counterclockwise rotation, place the cover on the tabs of the latches. This completes the replacement procedure.

removing the trimmer head cover

At the first stage of disassembly, the trimmer head cover is removed. In the example of Black and Decker trimmer models and others, to remove the cover, it is usually enough to apply some pressure to depress the locking latch that is located on the side of the head body.

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

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 lid slightly, after which the lid can be easily removed

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

How to replace the trimmer line?

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

However, before starting work on changing the line on the 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 mower:

  • exclude spontaneous start,
  • remove battery (if applicable),
  • place the tool on a platform convenient for work.

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

Step two: winding the cutting material in sections

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

In addition to the standard lawn line, my trimmer also has a thick line for cutting rough weeds. It has the shape of a pigtail, i.e. three lines are tightly intertwined. This line has its own spool.

Thick line

It is stored at the top of the trimmer body.

Storage space for spare coil

It is very simple to install such a fishing line into the reel. according to the internal scheme inside the reel. We insert the center of the line with a metal mount in the upper part of the reel, and draw the ends of the line along the grooves and bring it out.

Trimming the line into the trimmer.

I want to devote today’s article to the sore subject of summer residents and gardeners of the entire post-Soviet space “How to fill the line in the trimmer.” Not many trimmer manufacturers answer this question in their instruction manuals. Therefore, it is also difficult for simple gardeners to figure out how to do it correctly.

I want to start with a brief description of the technical characteristics of the trimmers.

So, trimmers are electric and gasoline. The cutting element for trimmers can be a line and a knife. The line is ordinary, four. pentahedral and intertwined (in the form of a pigtail). Knives come in 2, 3 and 4 bladed knives. Knives also come in plastic and metal.

The line feed system from the trimmer is manual, semi-automatic and automatic.

The development engineers who create new models of trimmers accurately calculate the diameter (thickness) of the line and the number of knife blades, according to the power of the trimmers. Otherwise, the engine is overloaded, resulting in damage to the engine. And these are additional and significant costs.

Trimmers on the market today:

With one nozzle. only a line.
With two nozzles. a fishing line and a three-four-blade knife.
With one nozzle. only three to four blades.

Our Kulibins have long ago learned to improve any mechanisms. So, for example, some gardeners make successful, in their opinion, replacement of fishing line with a metal cable, or fishing line. But at the same time, they do not think about the safety of their own and their loved ones, because, like a cable with the power of a working trimmer, it can easily break out and not only injure the mower and others, but leave him crippled for life. Using a fishing line can and gives a better effect, I have never personally tried it than a trimmer line, but such work has a number of inconveniences: when it comes into contact with hard objects, it loosens or can simply be pulled out of the reel without limit.

So, what is called closer to the topic. Here is an example of how to thread the line into the trimmer (Trimmer BOSCH Art 30). Everything is very simple. Started.

After you have chosen the line for refueling, you need to cut off the required amount of line, because all the line in a skein will not be wound into a reel.

Cut off and start reeling.

Remove the coil and the protective cover from the coil.

They took it off. We fix one end of the line in the gap and carefully and evenly wind the line.

The amount of line should be such that the protective cover of the reel closes and the line on the reel unwinds a little by itself.

We put the other end of the line into the hole on the protective casing.

Next, we take the coil and the protective cover of the coil. We squirt the end of the line from the reel into the metal hole on the reel’s protective cover. Tighten the line a little.

We put it all on the trimmer. Turn the coil clockwise until it clicks.

They fixed it. Now we connect the trimmer to the network. We put the trimmer in the starting position for work. We turn on the trimmer. Excess line length will be cut on the trimming blade.

How to choose a trimmer line

The trimmer is truly the right solution for cutting grass in areas that are difficult to reach for a wheeled lawnmower, such as around trees, bushes, along fences and paths. The performance of the unit directly depends on the correct choice of line for the trimmer. Cutting tooling requires flexibility, rigidity, and unbreakability. It must have a high level of durability and tear strength. What to look for first when choosing a trimmer line?

First, the thickness of the thread. In the individual instruction manual for the trimmer, you can find out the required line diameter. It is important to note that you do not need to be guided only by the inscriptions on the bobbin of the lawn mower, as the trimmer kit usually includes universal spools that are suitable for lines of different diameters and engines of different powers. Each trimmer model has its own individual line diameter. So, when installing a fishing line, the diameter of which exceeds the limit value indicated in the operating manual, the resistance to rotation increases, the load on the engine increases, which inevitably leads to overheating and breakdown. Of course, using a fishing line with a smaller diameter will not lead to engine breakdown, but it will significantly increase its wear. Currently, the most common thread is from 1.2 mm to 4 mm in diameter. Line diameter variation depends on engine power. For example, for electric or cordless trimmers, which are characterized by low power, a line with a diameter of 1.3. 1.6 mm is suitable. For more powerful electric or gasoline trimmers that can cut any grassy vegetation, a 1.8. 2 mm thread will work. On professional benzo and electric scythes, a thread with a thickness of 2.5. 4 mm is used. Such a fishing line will be quite enough to clear the area from small shrubs.

Secondly, the shape of the section. In most cases, a round trimmer line is sufficient. it is the most common and affordable. The main disadvantage of such a line is the high noise level produced by the trimmer during operation. But here, too, modern technology does not stand still. line manufacturers have been able to reduce noise by using a spiral line. Also, there are star, rectangular or square cross-sections. These sections have sharp edges, which makes the cut of the grass smoother. The curly shape of the fiber increases the productivity of the technique. However, at the same time, the consumption of the line increases, and when using such a thread, problems of feeding from the spool often arise. For the best possible mowing of grass, there are variants with notches and teeth. The notched line is designed for mowing weeds and tough vegetation. The main disadvantage of such a fishing line is poor retrieval from semi-automatic spools, so it uses discs into which it is inserted in small pieces. Two-piece round line is more tear-resistant and best suited for dry and tough grass.

Thirdly, the service life directly depends on the composition of the line. The most common trimmer line is nylon. This thread has a high degree of wear resistance, and also provides efficient operation at elevated temperatures and loads. In addition, it does not lose its qualities at low temperatures, and does not exfoliate during long-term storage.

The main advantage in favor of choosing a fishing line over other cutting equipment is the ability to use it for delicate trimming of vegetation, for example, near young trees or small bushes.

Line problems

Trimmer users, both gasoline and electric, sometimes have cord problems. “Advanced” mower owners can easily cope with the difficulties that have arisen, understanding why this is happening, and for beginners it is a problem that has no rational explanation. But in fact, everything is solved quite simply. The most common problems that happen with the line are as follows.

Cord breaks

If the line breaks frequently, this may be due to the following reasons:

  • stones, small branches and other solid obstacles come across in the grass;
  • the user mows the grass close to the fence, and if it is mesh, then it breaks off the “antennae” even faster;
  • poor quality of the cord (it is recommended to purchase a high-quality one);
  • the outlet holes in the mowing head are worn out, due to which the line is erased on the sharp edges of the bushings and breaks off (a complete replacement of the part is required).

Second way

Some spools provide a second method of securing the cord: you can charge 2 pieces of thread instead of one folded in half. The line is replaced according to the following algorithm.

  • Before changing or loading a new thread into the spool, determine how many meters it will take using the method described above.
  • Bend one end of the cord into a hook.
  • Find the hole in the bottom of the bobbin for the line to be fixed, and insert the looped end of the thread into it.
  • It is required to wind the cord according to the direction of the arrow to the required level not exceeding the spool diameter.
  • Do the same for the second bobbin compartment.
  • The assembly of the head is no different from the method that was given when threading the bobbin with a half-folded piece of fishing line was considered.

For Shtil lawn mowers, there is a very simple and quick way to replace the line without disassembling the mowing head, which you can familiarize yourself with by watching this video.

The ends of the cord protruding from the holes in the casing can be cut to the required length when the part is installed in the trimmer. This can be done in two ways:

  • turning on the trimmer (when rotating, the ends of the fishing line will be cut against the knife fixed for this purpose on the protective casing);
  • cutting off the excess ends with scissors so that they do not touch the casing body.

The second method is used if it was necessary to supply a large diameter cord, and the edging knife cannot shorten it.

If the filament has been loaded into the mowing head, but the length of the protruding ends of the cord is not enough, then they must be lengthened before starting the machine. this applies to the head with manual adjustment. However, there are cases when using a semi-automatic mowing head, when, due to the insufficient length of the protruding ends of the cord, they do not lengthen automatically. In this case, it is necessary to turn off the unit (on an electrical device, it is necessary to unplug the plug from the socket), manually press the button located at the bottom of the part and pull out a little line. After this procedure, the cord can again be extended due to centrifugal force, if you set the maximum spindle speed.

Regardless of the thickness of the line you set, you should remember: in order not to constantly interrupt work and not change the line, you should avoid areas where the working tool can touch hard surfaces (stones, curbs, thick dry branches, etc.).

The line is flying out

The reason that the cord unwinds after starting the unit can also be a weakening of the spring inside the head. In addition, there are times when the mowing head flies apart when the machine is turned on, and the spring installed in it is lost. Inexperienced users do not notice the absence of a spring and assemble this unit without it. Therefore, the cord does not hold, and under the influence of centrifugal force flies out.

The first way

To correctly determine how many meters of line is required for a particular reel, it is necessary to wind it on the bobbin so that the skein does not exceed the diameter of the sides. If the line sticks out over the edges of the spool, you will not be able to insert it into the casing. After you have decided on the length of the material, it must be threaded into the bobbin, so do the following.

  • It is necessary to fold the fishing line in half so that one end of it is 10-15 cm longer from the other.
  • Please note that the bobbin is divided into 2 parts by the central collar, from which charging begins. Find a groove on it and insert a cord bent in half into it, applying a little force.
  • It is very important to determine in which direction the line is wound onto the reel. If you look closely, you can find an arrow on the bobbin or an inscription with an arrow indicating in which direction the winding should be carried out. There are times when there is no arrow on the reel. In such a situation, you can look at the arrow drawn on the mowing head and wind the cord in the opposite direction.
  • Winding should be done carefully, turn by turn, with maximum thread tension.
  • After the laying of the cord is completed, you will first need to fix the short end of the line by inserting it into a groove of a suitable diameter on the side of the reel.
  • The second end, the one that is longer, is fastened in a groove on the opposite side of the bobbin.
  • After fixing the fishing line, cut off its ends, leaving an allowance of about 10 cm.
  • Next, you need to install the loaded bobbin into the mowing head. To do this, alternately inserting and pulling the thread into the outlet holes of the head, place the bobbin in the casing, then, applying the required force, pull the fishing line out of the fixing grooves and tighten it.
  • Now you can put on the cover and fix it with the latches.

How to remove and disassemble a coil

Before starting the cord replacement process, trimmer users need to remove and disassemble the reel. Let’s see how to do it.

The trimmer mowing head consists of several parts: a cover, a spring (not on all models), a bobbin with a cord and a cover.

Attention! Before proceeding with any maintenance of the electrical unit, it must be disconnected from the mains.

In trimmers, 2 options for mounting the mowing head are most often used.

How to change the line in the trimmer

The trimmer is the most common machine used for cutting grass and small bushes. This device is distinguished by its simplicity in service, simple operation during operation, and due to its low weight, even women can handle it. It is no secret that for high-quality performance of work on mowing grass, the correct selection of cutting tools is required. As the latter, special cutting attachments (discs, knives) or trimmer heads with a fishing line inside are used in trimmers. Nozzles and fishing line are consumable tools, but if the knives can be sharpened, then when the line is used up, it must be replaced. In this article, we will tell you in as much detail as possible how to properly replace the fishing line.

High cord consumption

In general, the cord runs out quickly if the semi-automatic head is tapped frequently on the ground or if it is pressed down hard. The spool is unlocked, and the line, lengthening, is cut with a knife. Another reason that the cord runs out quickly is improper operation of the machine with an automatic head: the user often cuts the engine speed when mowing. But as we remember, the automatic head is designed in such a way that it is with each decrease in speed that a new portion of the line is supplied, so it is quickly consumed.

Choosing a trimmer line

In order to choose the right line for the trimmer, the following parameters should be taken into account:

  • cord thickness;
  • sectional shape;
  • material from which the line is made.

Line thickness

The selection of the correct cord thickness is essential. It must match the characteristics of a particular device. If the line is with a large diameter, which is designed for a particular trimmer model, this can lead to tangling of the thread on the spool, overheating of the engine and rapid wear of the bushings.

The trimmer line can be sized from 1.2mm to 4mm. You can make such a conditional separation:

  • Line with a thickness of 1.2. 1.6 mm. It is designed for devices with low power. up to 0.5 kW. As a rule, these are electrical models.
  • Cord 2. 2.4 mm thick. This is the most common size and is suitable for cutting both young and tough grass. This line is installed on trimmers with a power of 1 kW.
  • 3. 3.2mm thick line. designed for high power petrol trimmers that can cut thick stems.
  • Cord 4 mm thick. This is the thickest trimmer line that can handle not only tough grass, but even shrub stalks.

Sectional shape

The shape of the thread is also an important parameter when choosing a trimmer line. This is due to the fact that the process of cutting a grass stem occurs as follows: the fishing line separates its part, not cutting, but interrupting it. According to the sectional shape, the cords are divided into the following types:

  • Round. This is a versatile shape that is suitable for cutting both fresh and dry grass;
  • multifaceted, which has from 3 to 6 faces. This line is capable of handling tough and thick stems. With all the advantages of the cord, it also has a disadvantage: fast consumption. Therefore, it is recommended to use it exclusively for its intended purpose;
  • curly. in the form of stars, squares with recesses. They have their own characteristics of purpose. For example, an asterisk is used to cut fresh grass.

Which trimmer line is better?

The trimmer is an essential tool for cutting lawn and other vegetation. He is able to become an indispensable assistant for owners of private houses and summer cottages, as it helps to maintain the adjacent territory in a tidy condition. In order to choose a trimmer model that will carry out the work with the highest quality and serve faithfully for many years, you need to pay special attention to all the constituent parts of the device. One of the questions to be solved is which trimmer line is better.?

Production material for fishing line

As a rule, nylon line is used for the trimmer. made of polyamide or polypropylene. The cheaper version contains the addition of polyethylene. It is not recommended to use it, since the cord, which contains such a material, is characterized by a reduced resistance to wear and temperature.

To extend the life of a polypropylene line, it is soaked in water for half an hour before direct use. Many people have a question: which is the strongest trimmer line? These can be called strings with a large diameter (about 4 mm), into which aluminum particles are specially added.

Some people practice using metal wire or cables for lawn mowers, which is absolutely impossible to do. It is best to use metal trimmer line, which is the most reliable.

In addition, the reinforced trimmer line, which consists of an outer layer and a dense core, is considered extra strong. This ensures its high wear resistance.

Thus, having the necessary information about the characteristics of the trimmer line, you can choose the best option for yourself.
