Electric trimmer repair with their own hands: detailed instructions for the novice craftsman with pictures, diagrams and photos

Mowing string head is a type of the executive mechanism of the garden trimmer for grass. It is designed for mowing grass and represents a special spool (bobbin), from which the cutting cord (string, line for trimmer) stick out in different directions. String in this case is a consumable material that must be replaced during operation. Based on the design and operational features of the trimmer for grass, manufacturing companies equip their products with the most diverse types of heads. from simple hand reels to complex automatic reels. The more complex is the construction of the mechanism, the more likely is it to malfunction. What to do if the spool doesn’t spin, the string doesn’t feed or breaks, as well as other malfunctions. see the material below.

Modern cultivator attachments can be made in two designs:

Despite the different names and designs, by and large the fundamental difference is only in the form of the ripping unit.

Toothed grass trimmer nozzles have less weight, and therefore are better suited for processing light soils. As for the disc models, they are used for loosening heavier soils, since they have greater rigidity.

The torque is transmitted to the mowing head by the engine through a shaft, which is linked by a special connecting rod. The latter, unfortunately, often has to be bought separately.

The considered unit can not be called interchangeable, and the number of slots on the end part of the rod can vary from 7 to 9. On this basis, buying a nozzle-cultivator, for example, from Oleo-Mac is worth knowing that it will not work with the trimmer brand Husqvarna, as well as vice versa.

The importance of proper reeling

In order to have a successful fishing trip, it is necessary to prepare for it thoroughly. Otherwise a “terrible thing” can happen. the weather is fine, the bite is great, but the tackle keeps failing and prevents to take advantage of favorable fishing conditions.

To avoid this happening, it is necessary to set up all fishing equipment in advance. One of the most important stages of preparation for fishing is the correct winding of the line on the bobbin of the fishing reel. Failure to follow the basic rules threatens the poor angler with tangles and breaks in the line, and fishing instead of pleasure will be a test for the nervous system.

The quality of such work determines the throwing range. Correct reeling ensures that the bait is thrown at a distance that best matches the specifications of the reel.

In addition, high-quality winding prolongs the life of the line, reducing mechanical friction and reducing the risk of “beard” when throwing, because of which it is often necessary to cut the line for trimmer. Therefore, before starting work, it is necessary to consider a few tips from experienced fishermen on how to lay the line on the bobbin. This is a fairly straightforward procedure that even a novice can do.

Preparing for replacement

To make it clear, the mowing head (the bobbin) was removed from the brushcutter. To change the line there is no need to remove it, everything is done in place. It doesn’t take long.

Dismantle the grass trimmer bobbin. it is held on the latches. Remove the cover by pushing on the catches. If your hands are not strong enough to do this, use a screwdriver.

The bobbin consists of the following:

The principle of operation is as follows. Pressing the button, the bobbin presses on the spring and comes out of the retaining grooves in the cover of the bobbin. Holding in this state, the spool can be twisted, thereby adjusting the length of the line. When you release the button, the body spring returns the coil to its original locked position.

Main faults of the reel

Users of electric trimmer and lawnmower often face a problem related to the semi-automatic mowing head. Faults in the reel may be the following:

If the grass trimmer spool button lightly strikes the ground and the trimmer line does not lengthen, then the causes of this may be.

Option 1. jamming has occurred, t.е. the filament is caught between the coils. This problem usually occurs if the user has wound the trimmer line unevenly, with overlapping coils, or has 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 tighten, resulting in a possible inter-scroll jamming of the line. To fix the problem, you have to disassemble the coil on the trimmer and rewind the cord correctly, i.e. with even coils and good tension.

Option 2. the ends are too short and protrude from the head. The trimmer line may not come out when hitting the ground, if its ends sticking out of the head are not long enough (short). In this case the centrifugal force is not enough to pull the trimmer line. It is therefore necessary to stop the machine (turn off the engine or unplug the electric grass trimmer) and pull the trimmer line manually by pushing the button.

Variant 3. trimmer line is soldered inside the mowing head. This causes the spool to stall and not spin when the button is pressed. This generally occurs for several reasons: poor quality cord, overheating of the reel during prolonged use of the machine, and bumping of the line against hard objects.

  • In the first case, the third-party cord can be made from low-quality and fusible materials that can not withstand mechanical and thermal loads. Therefore, you should give preference to “branded” fishing lines.
  • But, if you still bought a line for your trimmer of unknown quality and it often solders while working, you can follow the example of some users who, after threading the cord into the reel, wet it either with silicone grease (from a spray can) or mineral oil. This procedure greatly reduces the likelihood of soldering the coils of fishing line to each other.
  • Also, the line for the trimmer may melt if it hits a hard object (a rock, a fence, a dry branch, etc.) while mowing.д.). As a result, it stretches a little and pulls back into the head at a high rate. The friction heats the cord and causes it to stick together. The only thing you can do to fix this problem is to open the grass trimmer reel and rewind the trimmer line.

There are situations when the grass trimmer user notices a very fast consumption of the fishing line. Never hit the button on the ground to lengthen the line. The reason that the line for the trimmer unintentionally lengthens, being cut on a special knife on the hood of the device, may be the lack of spring in the mowing head.

How to tuck the trimmer line into the grass trimmer reel

It takes about 10-15 minutes to wind the mowing line. What is a grass trimmer reel? A plastic body with a cassette inside that has a special hook for easy winding of fishing line. Almost all trimmer spools have a similar attachment principle, it is a central screw button, when pressed it becomes possible to extract the line for the trimmer of the desired length. The photo below shows several examples of different trimmer bobbins.

The pins of trimmers, whose motor is located on the ground, have a different attachment to the axis of rotation, they have two buttons on the reel, located on the sides, which must be unscrewed, otherwise the change of the line is no different from other cassettes.

The principle of correctly winding a mower line is similar in all of the above

cases, so, for example, consider the standard version with two antennas.

To remove the spool with the line, you need to unscrew the screw located in the center, but note that the thread has remained there, so you have to return it clockwise, this was done on purpose, so that during operation it will not open under the action of centrifugal force.

Next, using a screwdriver, remove the head and remove the spool, which is directly wound string

What types of fishing lines are

A common type of fishing line that fits virtually all types of spools is round cord. This is an ordinary line for trimmer, suitable for mowing lush grass, but it will be much harder to mow dead grass, and even more so it can not cope with the bushes.

Usually, the cross section, with which young grass can be mowed, does not exceed 1,6 mm. The thicker the thread, the coarser the grass it can cut.

There is a line with sharpened facets in the form of a star or a square, this version is more adapted to mowing dry grass just by having a sharp edge, but the disadvantage is its greater wear and tear and inferior in strength round cord.

There are lines with improved aerodynamics with appropriate dents, scales and notches, a similar product makes less noise, but use it only on benzokosa, since the output of such thread from the spool is difficult, using it in most cases with discs, which are inserted segments. The disadvantage of such a product is its fragility.

In most cases petrol trimmers with engines of more than 1.5 liters.с. Use a cord with an iron rope inside.

Such cord is perfectly suitable for mowing dry grass and small bushes. The presence of the core, has a positive effect on the durability of this material.

The disadvantage of such cord is its cost, which is much higher than the above-listed opponents.

Self-made bobbin

Grass trimmer is often used far from places where you can buy spare parts for the mowing head when it breaks. In this case instead of a broken mechanism you can install a simple design spool, made by your own hands. For this you will need a sheet of plywood (textolite, metal, etc.) and a piece of wood.), eyelets, screws or screws. The process involves several steps.

  • From a plywood sheet cut disk, diameter corresponding to the failed bobbin.
  • In the center of the disk drill a hole that matches the diameter of the shaft of the grass trimmer.
  • On the opposite sides of the disc, small eyelets are fastened that will serve for threading the line.
  • The line for the trimmer is threaded through the eyelets and secured with usual screws or bolts. The spool is ready for use.

Important! Remember that you can not tighten or unscrew the nut without fixing the shaft firmly.

To replace the line on a homemade reel it is necessary to release the fixing screws, insert a new piece of string and tighten the fasteners again. Remove the spool from the shaft of the trimmer for grass in this case is not necessary, but it is necessary to exclude the possibility of spontaneous starting the motor.
