How to remove the head on the Black trimmerDecker 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 is acidic and firmly in place, then add light swaying movements to the efforts, periodically changing the places of their application. Do not use force or shock. The case is plastic and it is quite easy to damage it.

By size

Before winding the thread on the trimmer spool, you should pay attention to its size. Most often, a line with a cross section of 2 mm is used.

You can choose a suitable diameter in the following ways:

  1. See the manufacturer’s instructions for the trimmer for recommendations.
  2. Manufacturers often apply cross section information to the bobbin.
  3. The cross-section of the cord must match the diameter of the spool hole.

How to wind the line around the reel of the double barb trimmer

You can look before work, and also take into account the following recommendations.

  1. If there is only one track, both threads are wound in parallel.
  2. If there are two tracks, each section is wound in a separate groove.
  3. Wind the threads in the opposite direction to the rotation of the head.
  4. The length of the free ends should not exceed fifteen centimeters.
  5. Thread the ends through the outlet holes.
  6. Assemble the head and check the trimmer performance.

By quality

Before putting on the line on the trimmer, you need to pay attention to the section of the cord:

  • Round threads are the most common option. They cut the grass perfectly, even in difficult areas;
  • Coiled line is suitable for thin grass. It is not very durable and is not suitable for old thickets;
  • A cord with notches and sharp edges is chosen for mowing weeds;
  • Fishing line with a variety of geometric sections will help to mow the lawn more evenly, but the consumable strength is low.

The owner of the lawn mower should know that it is absolutely forbidden to use metal wire, fishing thread and various strings.

How to quickly and easily remove the coil with your own hands

Remove the head before replacing the old line with a new one in the detachable trimmer reel.

The process is completely simple, even beginners can do the job:

  1. Remove the upper retaining cover.
  2. Take out the removable spool.
  3. Take out the spring, if any.
  4. Unscrew the bolt with a screwdriver.
  5. Remove the housing from the shaft.

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 has 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 trimmer from the mains) and pull the line manually, after pressing the button.

Option 3. The line is soldered 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, line hitting hard objects.

  1. 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.
  2. 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 threading the cord into a reel, wet it either silicone grease (from a spray can), or mineral oil. This procedure greatly reduces the likelihood of the coils of the fishing line being soldered together.
  3. Also, the line can be soldered if it hits a hard object (stone, fence, dry branch, etc.) during mowing. As a result, it stretches slightly 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 coil and rewind the line.

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.

  1. Stop the mowers engine or power off the trimmer before threading the spool to avoid injury from accidental starting rotation of the cutter.
  2. Unscrew the nozzle attached to gear 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.
  3. Unscrew the nozzle. Be aware that the thread on the shaft is left-handed. Therefore, turn the trimmer coil to the right, that is, clockwise.
  4. Disassemble the mowing head. Most often, the head cover is attached on latches. 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.
  5. 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.
  6. Find the midpoint of the line by folding it in half. You will have a loop.
  7. Coils are cut inside special grooves (there may be holes). Insert a loop of line into this slot.
  8. 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.
  9. Assemble the mowing head. Before you finally assemble the attachment, be sure to insert spring and washer (if available). Place the spool in the body and thread the ends of the cord through the holes or eyelets.
  10. Put on the cover and secure it with the latches.
  11. 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).

DIY trimmer coil repair

The trimmer, whether petrol or electric, 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 corrected by hand, and some require a complete replacement of the mowing head.
