How To Remove The Head On A Bosch Trimmer

The trimmer, whether it is gasoline in another electronic way, is the only right solution for mowing grass in inaccessible places with which the wheeled lawnmower does not control. For the cutting tool in the trimmers used iron knives or a special fishing line, which is tucked into the coil of the trimmer. But, unfortunately, trimmer heads in the process of use over the years come into disrepair. Some malfunctions are an option to remove on their own, and with some, a complete change of the mowing head is useful.

Mowing heads for trimmers come in various designs. Both conventional and complex. The picture below shows automatic trimmer head from the Husqvarna lawn mowers (Husqvarna) disassembled.

This type of head is in the configuration of most lawnmowers and trimmers, such as Stihl (Stihl), Patriot (Patriot), Champion (Favorite), Bosch (Bosch), Huter (Huter) and others. The mowing head arrangement is quite ordinary. It consists of the following details:

  • Mowing head base;
  • Button for automatic cord feeding;
  • A bobbin (reel) where the fishing line is refueled;
  • Spring;
  • Eyes. Through their fishing line comes out;
  • Trimmer head cover;
  • Fishing line (cord).

There are also more ordinary trimmer heads shown in the following photo.

These nozzles do not allow you to change the length of the fishing line in automatic mode (after pressing the button). For which the cord break design is intended, it is necessary to stop the mower and change it manually.

Trimmer users and lawn mowers often encounter a problem associated with an automatic mowing head. Coil malfunctions are as follows:

Self-winding lawn mowing coil, USA manufacturer

  • The fishing line is not extended automatically;
  • The cord spontaneously exits the coil.

If the line does not lengthen with a light blow of the trimmer coil button on the ground, then the prerequisites for this are usually the following.

Option 1. Bite out, i.E. Clamping cord between turns. This problem usually occurs if the user wound the fishing line on the reel unevenly, with the crossing of windings, or wound it with a missing tension. In the latter case, when the mowing head rotates at tremendous speed under the influence of centrifugal force, the cord begins to tighten, under the influence of which there may be inter-turn clamping of the fishing line. To eliminate the obstacles, you will have to disassemble the coil on the trimmer and rewind the cord correctly, in other words, even turns with good tension.

Option 2.4. Very short ends protrude from the head. The fishing line may not come out when it hits the ground, if its ends protruding from the head are of insufficient length (short). Then centrifugal force is not enough to stretch the fishing line. Therefore, it is necessary to suspend the unit (to muffle the engine in another way, disconnect the trimmer from the network) and pull out the fishing line manually, by pressing the button earlier.

Option 3. Fishing line soldered inside the mowing head. This leads to the fact that the coil stops and does not even turn when the button is pressed. For the most part, this happens for several reasons: poor cord quality, overheating of the coil during prolonged operation of the machine, and fishing line impact on solid objects.

  1. At the beginning, the cord of other manufacturers you will like is made of low-quality and fusible materials that do not hold the mechanical and temperature loads. Therefore, preference should be given to “branded” fishing lines.
  2. If you still get a fishing line of an unknown property, and it often gets soldered in due time, then of course follow the example of some users who, after refueling the cord into a coil, moisten it or silicone grease (from spray can), or mineral oil. This procedure greatly reduces the possibility of soldering with each other turns of fishing line.
  3. Also, the fishing line can be soldered if, at the time of mowing, it hits a hard object (stone, fence, dry branch, etc.). During this, it stretches slightly and is pulled back into the head at high speed. The cord warms up from friction, and its coils stick together. The only thing that will be done to eliminate this malfunction is to open the trimmer coil and rewind the fishing line.

There are situations when the user of the trimmer notices very fast fishing line consumption. Here, he never once hit the ground with a button to lengthen the fishing line. A prerequisite that the fishing line spontaneously lengthens, cutting off a special knife on the machine’s casing, is lack of spring in the mowing head. Often, beginning users of mowers, trying to charge the fishing line into a reel, forget to install a pressing spring in the head, in other words, completely lose it when the lid is opened, and then they do not even suspect its existence.

Also, the line is lengthened without using a button if the spring is weakened. If the spring check confirmed this fact, then several washers must be slipped under it to strengthen its pressing characteristics.

Owners of trimmers, mostly new ones, are confused, adjacent to panic, when there is a need to change the cutting tool or fishing line in the reel. Often when trying to unscrew the mowing head, users simply render it unusable, not suspecting that it is unscrewed in the opposite direction. To prevent this, if you need to change the tool, it is recommended to join the step-by-step annotation below.

  1. Before filling the fishing line into the reel, turn off the engine of the lawn mowers, as it is also called, de-energize the trimmer to avoid injuries that occur when the cutting tool is accidentally started to rotate.
  2. Unscrew the nozzle attached to gear shaft. To do this, the shaft needs to be fixed by aligning the holes on the washer on the axis and inserting an iron bar or a screwdriver there.
  3. Unscrew the nozzle. You need to know that the thread on the shaft is left. Therefore, twist the trimmer coil to the right, in other words, clockwise.
  4. Disassemble the mowing head. In most cases, the head cover is attached on clips. To remove it, you will need to drown these clips into the body, squeezing the edges of the lid. If there is a passage, if an automatic mowing head with a button on the bottom is installed on your trimmer, disassembling the nozzle should be done carefully, as there is an option to lose the spring, which flies from time to time during the removal of the cover.
  5. Cut the right amount of fishing line. Usually its length is 5 meters. Use a cord of such a diameter as indicated in the annotation to the instrument. It is not recommended to exceed the largest diameter of the line, as this will lead to an increased load on the engine and a higher consumption of gasoline.
  6. Find the middle of the cord segment, folding it in half. You will get a loop.
  7. Coils cut through the inside special grooves (holes happen). Insert a loop from the fishing line into such a groove.
  8. Wind the line onto the reel by turning it counterclockwise. It is necessary to refuel the cord very evenly, the turns must be laid down without overlapping and with good tension. When the winding is finished, leave the free ends of the fishing line about 20 cm long and fix them in the grooves located on the sides of the reel.
  9. Assemble the mowing head. Before you completely assemble the nozzle, do not forget stick spring and washer (if available). Install the coil in the housing, and thread the ends of the cord through the holes or eyes.
  10. Put on the cover and fix it with the latches.
  11. Screw the nozzle back onto the gearbox shaft, also locking it with a screwdriver. Spin the trimmer coil to the left (against the clockwise arrow).
  1. Take a piece of plywood or textolite and draw a circle with a diameter of about 14 cm.
  2. Cut the disc with a jigsaw as it is also called hacksaw.
  3. Drill a hole in the center of the disc that fits across the shaft of the gearbox. And before installing the disk on the shaft, put a washer on this address.
  4. On the sides of the disk, of course, screw in small corners, as it is also called, make 1-2 holes on the reverse sides. They will serve to refuel their fishing line.
  5. To fix the fishing line, of course, screw a few screws into the plywood.

Trimmer Coil Device

Mowing heads for trimmers come in many designs. Both simple and complex. The picture below shows semi-automatic trimmer head from the Husqvarna lawn mowers (Husqvarna) disassembled.

This type of head is present in the configuration of most lawnmowers and trimmers, such as Stihl (Stihl), Patriot (Patriot), Champion (Champion), Bosch (Bosch), Huter (Huter) and others. The mower head is quite simple. It consists of the following details:

  • Mowing head base;
  • Button for semi-automatic cord feeding;
  • A bobbin (reel) into which the fishing line is refueled;
  • Spring;
  • Eyes. Through them the fishing line comes out;
  • Trimmer head cover;
  • Fishing line (cord).

There are also simpler trimmer heads shown in the following photo.

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

Basic coil faults

Trimmer users and lawn mowers often encounter a problem with a semi-automatic mowing head. Coil malfunctions can be as follows:

  • The fishing line does not automatically extend;
  • The cord spontaneously exits the coil.

The fishing line does not automatically extend

If the line does not lengthen with a light touch of the trimmer coil button on the ground, the reasons for this may be as follows.

Option 1. A bite occurred, i.E. Clamping cord between turns. This problem usually occurs if the user wound the fishing line on the reel unevenly, with the intersection of turns, or wound 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 drag out, as a result of which it is possible to twist the fishing line. 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 fishing line may not come out when it hits the ground, if its ends protruding from the head are of insufficient length (short). In this case, centrifugal force is not enough to stretch the line. Therefore, it is necessary to stop the unit (turn off the engine or disconnect the trimmer from the mains) and pull out the fishing line manually by first pressing the button.

Option 3. Fishing line soldered inside the mowing head. This causes the coil to stop and not spin when the button is pressed. Basically, this happens for several reasons: poor quality of the cord, overheating of the coil during continuous operation of the unit, impact of fishing line on solid objects.

  1. In the first case, the cord of third-party manufacturers can be made of low-quality and low-melting materials that do not withstand mechanical and thermal stress. Therefore, preference should be given to “branded” fishing lines.
  2. But, if you nevertheless acquired a fishing line of unknown quality, and it often gets soldered during operation, then you can follow the example of some users who, after refueling the cord into a coil, moisten it either silicone grease (from spray can), or mineral oil. This procedure greatly reduces the likelihood of soldering between each other turns of fishing line.
  3. Also, the fishing line can be soldered if during mowing it hits a solid object (stone, fence, dry branch, etc.). As a result of this, it stretches a little and is pulled back into the head at high speed. The cord heats up due to friction, and its coils stick together. The only thing that can be done to eliminate this malfunction is to open the trimmer coil and rewind the fishing line.

Cord spontaneously lengthens

There are situations when the trimmer user notices very fast consumption of fishing line. However, he never hit a button on the ground to lengthen the fishing line. The reason that the fishing line spontaneously lengthens, cutting off a special knife on the casing of the device, can serve lack of spring in the mowing head. Often, novice users of mowers, trying to charge the fishing line into a reel, forget to install the hold-down spring in the head, or even lose it when the lid is opened, and in the future, they are not even aware of its existence.

How to remove the reel and replace the fishing line

Owners of trimmers, mostly novices, are confused, bordering on panic when it becomes necessary to change the cutting tool or fishing 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, if you need to replace the tool, it is recommended that you read the step-by-step instructions below.

  1. Before putting the fishing line into the reel, turn off the engine of the lawn mowers or de-energize the trimmer to avoid injuries that might occur if the cutting tool is accidentally started to rotate.
  2. Unscrew the nozzle attached to gear shaft. To do this, the shaft must be locked by aligning the holes on the washer and on the axis, and inserting a metal rod or screwdriver into them.
  3. Unscrew the nozzle. You should know that the thread on the shaft is left. Therefore, twist the trimmer coil to the right, that is, clockwise.
  4. Disassemble the mowing head. Most often, the head cover is attached on clips. To remove it, you will need to drown these clips into the body, squeezing the edges of the lid. If your trimmer has a semi-automatic mowing head with a button on the bottom, disassembling the nozzle should be done carefully, since you can lose the spring, which sometimes flies out when the cover is removed.
  5. Cut the required amount of fishing line. Usually its length is 5 meters. Use a cord of the diameter specified in the tool manual. It is not recommended to exceed the maximum diameter of the fishing line, as this will lead to increased engine load and higher gas mileage.
  6. Find the middle of the cord segment, folding it in half. You will get a loop.
  7. Cut through the coils special grooves (there may be holes). Insert a loop from the fishing line into this groove.
  8. Wind the line onto the reel by turning it counterclockwise. It is necessary to refuel the cord as evenly as possible, the turns should lie down without overlapping and with good tension. When the winding is finished, leave the free ends of the fishing line about 20 cm long and fix them in the grooves located on the sides of the reel.
  9. Assemble the mowing head. Before you finally assemble the nozzle, do not forget insert spring and washer (if available). Install the coil in the housing, and thread the ends of the cord through holes or eyes.
  10. Put on the cover and fix it with the latches.
  11. Screw the nozzle back onto the gearbox shaft, also locking it with a screwdriver. Spin the trimmer coil to the left (against the clockwise arrow).
