Replacing The Trimmer Head

Changing the line in the trimmer: 2 easy ways Change the line in the trimmer. How to disassemble the trimmer spool? How many ways are there to install a line? Step by step instructions with graphs.

Method 2 two segments

Two coiled line pieces

Method # 2 is fundamentally no different from method # 1. The only difference is that there are two winding lengths of line, instead of one.

The end of each segment is folded

The end of each segment is folded over.

Two special fixing sockets

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

We start winding the 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 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 made into the holes in the trimmer spool body. They are pulled until they click, which means that the line has come out of the clips.

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.

Changing the line in the trimmer: 2 easy ways

In this manual, we will 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.

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 on the dividing wall.

The line is inserted into the slot

The line is wound in the direction determined earlier. This is done in tightness, 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 the segment that is located at the bottom of the coil, i.E. The one closer 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.

A long segment is wound another half turn

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

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. This is easily identified by the characteristic sound (click).

The ends of the line pull up with effort

The spool with the button snaps into the trimmer spool housing.

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 to clarify the process of replacing the fishing line. You can disassemble the spool in place, wind it on the spool and put it back.

Line replacement completed successfully

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

Preparing for replacement

We disassemble the trimmer spool

For clarity, the mowing head (spool) was removed from the brushcutter. To replace the fishing line, you do not need to remove it, everything is done in place. 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
Reel with button

The principle of operation is as follows. By pressing the button, the spool presses on the spring and comes out of the fixing 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 (as here) they are signed, in others they are not.

These holes are needed to fix the line when changing 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 the outlet of the fishing line from the trimmer spool body (see the 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 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 will need a 4 meter segment, this is for the 1st method. For the second method, you need two segments of 2 meters.

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 reels, 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.

Step three: complete the head assembly

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

The final technical touch of the line change process 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 push downwards with a small counterclockwise rotation, place the cover on the tabs of the clips. This completes the replacement procedure.

-instruction: replacing the trimmer line

The above explains (using an 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 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 plant the knot in the groove made on each side of the winding drum.

Step 1: remove the trimmer head cover

At the first stage of disassembly, the trimmer head cover is removed. In the example of Black and Decker trimmers and others, to remove the cover, it is usually sufficient to apply some pressure to depress the locking latch 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 bezel.

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

When squeezing out the locking tab, you need to slightly turn and lift the trimmer head cover to remove the winding drum.

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

Trimmers (aka lawn mowers) are actively used by modern society to care for lawns and other similar objects of horticultural farms. The tool is noted for its high efficiency, despite the questionable quality of cutting the grass (compared to the usual peasant scythe land and sky). The main advantage of trimmers (lawn mowers) is high productivity with low physical effort of the operator. However, over time, the trimmer’s cutting element (nylon scaffolding) wears out or gets damaged, making the trimmer a useless tool as a result. Hence, the actual task becomes 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 from Black and Decker and others.

Installing a 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 lawn mower model:

How to replace, remove the BlackDecker GL716 trimmer head

No matter how well the electric trimmer purchased by us works in a summer cottage or a country house, sooner or later the time will come when we need remove the head trimmer for replacement or prevention. I will make a reservation right away that you do not need to completely remove the trimmer head to replace the fishing line. In this article I will tell you how to completely remove or replace the cutting head using the example of the BlackDecker GL716 electric trimmer.

How to remove the trimmer mowing head.

The design and fastening of the working part of the electric scooter differ significantly from different manufacturers. But given that there are many copies of less well-known brands in our markets, the described procedure may suit owners of other portable garden equipment for lawn and grass care.

Tool for changing the trimmer head.

To replace, remove the mowing head from the tool, we need an asterisk nozzle, usually supplied in the kit, or a flat wide screwdriver. Using a hexagon instead of an asterisk will not work, the nozzle slips, licking the edges of the asterisk on the screw.

How to remove a trimmer head on a BlackDecker GL716.

The trimmer has an overhead engine and curved bar. For ease of use, turn it over with the engine down or lay it horizontally. We disassemble the mowing head. To do this, simultaneously press the side latches and remove the top cover. Disconnect the line spool.

A slightly recessed dark screw is visible in the middle of the head body. We fix the head body with one hand and use an asterisk nozzle to unscrew the screw counterclockwise. If you don’t have a sprocket at hand, you can do this with a wide, flat screwdriver.

Now, pull the trimmer head towards you to remove it. If it sour and sits firmly in place, then add light swaying movements to the efforts, periodically changing the places of their application. Do not use harsh or impact forces. The case is plastic and it is quite easy to damage it.

Fitting the mowing head to the Black Decker trimmer.

Installing the mowing head to the trimmer is carried out in the reverse order. When the screw is replaced, it is tightened with medium force.

I wish you a successful summer cottage season and that the gardening equipment does not let you down. I hope my advice on how to remove the cutting head on the BlackDecker GL716 trimmer has saved you time and hassle.

The cord lengthens spontaneously

There are times when the trimmer user notices a very fast line flow. At the same time, he never hit the ground with a button to lengthen the line. The reason for the fact that the line spontaneously lengthens, being cut on a special knife on the casing of the device, may be the absence of a spring in the mowing head. Often, novice users of mowers, trying to load the line into the reel, forget to install the pressure spring in the head, or completely lose it when opening the lid, and in the future, do not even know about its existence.

How to remove the spool and replace the line

Trimmer owners, mostly beginners, find themselves in confusion, bordering on panic, when they need to change the cutting tool or line in the reel. Very often, when trying to unscrew the mowing head, users simply render it unusable, not suspecting that it is unscrewing in the opposite direction. To prevent this from happening, if you need to replace the tool, we recommend that you read the step-by-step instructions below.

Stop the brushcutter engine or power off the electric trimmer before threading the line into the reel to avoid injury from accidental starting rotation of the cutting tool.
Unscrew the nozzle attached to the gearbox shaft. To do this, the shaft must be fixed by aligning the holes on the washer and on the axle, and inserting a metal rod or screwdriver into them.
Unscrew the nozzle. You should be aware that the thread on the shaft is left-hand. Therefore, turn the trimmer coil to the right, that is, clockwise.
Disassemble the mowing head. Most often, the head cover is attached with clips. To remove it, you will need to sink these latches into the case, pressing the edges of the cover. If your trimmer has a semi-automatic mowing head with a button on the bottom, then the disassembly of the attachment should be done carefully, since you can lose the spring, which sometimes flies out when the cover is removed.
Cut off the required amount of line. Usually its length is 5 meters. Use a cord of the same diameter as indicated in the instructions for the tool. It is not recommended to exceed the maximum line diameter as this will result in increased engine stress and higher gas mileage.
Find the midpoint of the line by folding it in half. You will have a loop.
Special grooves are cut inside the coil (there may be holes). Insert a loop of line into this slot.
Wind the line around the spool by turning it counterclockwise. It is necessary to fill in the cord as evenly as possible, the turns should lie down without overlapping and with good tension. When the winding is complete, leave the free ends of the line about 20 cm long and fix them in the grooves on the sides of the reel.
Assemble the mowing head. Remember to insert the spring and washer (if equipped) before final assembly of the accessory. Place the spool in the body and thread the ends of the cord through the holes or eyelets.
Put on the cover and secure it with the latches.
Screw the adapter back onto the gearbox shaft, also securing it with a screwdriver. You will need to twist the trimmer coil to the left (counter-clockwise).

Line does not lengthen automatically

If the line does not lengthen when you lightly hit the trimmer button on the ground, then the reasons for this may be the following.

Option 1 a bite occurred, i.E. Clamping the cord between turns. This problem usually appears if the user has been winding the line on the reel unevenly, with intersecting turns, or winding it with insufficient tension. In the latter case, when the mowing head rotates at high speeds under the influence of centrifugal force, the cord begins to tighten, as a result of which inter-turn clamping of the fishing line is possible. To fix the problem, you will have to disassemble the coil on the trimmer and rewind the cord correctly, that is, in even turns with good tension.

Option 2 too short ends protrude from the head. The line may not come out when hitting the ground if the ends sticking out of the head are not long enough (short). In this case, the centrifugal force is not enough to stretch the line. Therefore, it is required to stop the unit (turn off the engine or disconnect the electric trimmer from the mains) and pull the line manually, after pressing the button.

Option 3 the line is brazed inside the mowing head. This causes the coil to lock and not spin when the button is pressed. Basically, this happens for several reasons: poor quality of the cord, overheating of the coil during prolonged operation of the unit, hitting the line against solid objects.

In the first case, third-party cord can be made of low-quality and low-melting materials that cannot withstand mechanical and temperature stress. Therefore, you should give preference to “branded” lines.
But, if you nevertheless purchased a fishing line of unknown quality, and it is often soldered during operation, then you can follow the example of some users who, after filling the cord into the reel, wet it with either silicone grease (from a can) or mineral oil. This procedure greatly reduces the likelihood of the coils of the line being soldered together.
Also, the line can be soldered if it hits a hard object (stone, fence, dry branch, etc.) during mowing. As a result, it stretches a little and is pulled back into the head at high speed. From friction, the cord heats up, and its turns stick together. The only thing that can be done to eliminate this malfunction is to open the trimmer spool and rewind the line.

Major coil faults

Users of electric trimmers and petrol cutters often face a problem with a semi-automatic mowing head. Coil malfunctions can be as follows:

The line does not lengthen automatically;
The cord spontaneously comes out of the spool.

DIY trimmer coil repair

A petrol or electric trimmer is the only solution for mowing grass in hard-to-reach places that a wheeled lawnmower cannot handle. As a cutting tool in trimmers, metal knives or a special line are used, which is tucked into the trimmer coil. But, unfortunately, the trimmer heads become unusable over time during operation. Some malfunctions can be eliminated by hand, and some require a complete replacement of the mowing head.

Trimmer coil device

Trimmer mowing heads come in a variety of designs, both simple and complex. The illustration below shows an exploded view of the semi-automatic trimmer head from a Husqvarna (Husqvarna) brushcutter.

This type of head is present on most mowers and electric trimmers, such as Stihl (Stihl), Patriot (Patriot), Champion (Champion), Bosch (Bosch), Huter (Huter) and others. The device of the mowing head is quite simple. It includes the following details:

Mowing head base;
Button for semi-automatic cord feed;
Bobbin (spool) into which the line is tucked;
Spring;
The eyes through them the line comes out;
Trimmer head cover;
Fishing line (cord).

There are also simpler trim heads as shown in the following.

All these attachments do not allow you to change the length of the line in a semi-automatic mode (after pressing a button). If the cord breaks, you have to stop the mower and change it manually.
