Characteristic malfunctions and their independent elimination

Naturally, during operation, the owners of the trimmers are faced with certain malfunctions of mowing heads. Over, they are most often associated with certain difficulties in pulling (lengthening) of the cutting cord from the coil. The most common causes of the lack of fishing line is its “bite” between the turns or sticking.

If the string is not served

In this case, the cause of the defect is incorrect winding of the cutting cord. A trimmer fishing line can be wound with insufficient tension, which helps to cross the turns together and confuse the string. When the coil rotates, the cutting cord under the influence of the emerging centrifugal force is delayed, which in turn leads to the clamping of the free end of the fishing line between the turns. To eliminate this malfunction, you need to dismantle the coil, disassemble it and rewind the string so that the turns lie down in even rows, pressing tightly against each other.

If the string sticks together

Squeezing the turns of the fishing line directly in the mowing head can be caused:

Advice! To avoid sticking the cord inside the mowing head, experts recommend applying a thin layer of silicone lubricant after refueling the string to the coil. In addition, it is better not to use a fishing line for a trimmer of unknown manufacturers.

When using semi-automatic mowing heads, the user can detect the accelerated consumption of the cutting cord due to its spontaneous lengthening.

If the bobbin does not spin

The refusal to work the semi.Automatic coil of the trimmer for the grass can also be caused by a frequent clash of its head with solid objects (dry branches, soil, stones, etc.). In this situation, there is a slight stretching of the fishing line, and then the rapid retraction of it inside the bobbin. Due to severe friction, the cord is heated, which can lead to sticking its turns to each other. To eliminate the defect, the string will need to be rewound.

If the string is served spontaneously

Spontaneous lengthening of the fishing line, followed by trimming its tips, may be caused by a violation of the order of assembly of the head after replacing the cutting cord.

The device is a trimmer head

In the Russian market, semi.Automatic trimmer heads are considered the most popular. A typical representative of the mechanisms of this type is a universal semi.Automatic head, which is equipped with electric trimmers for grass and lawn mowers such well.Known brands as Bosch, Huter, Husqvarna, etc. Its device is shown in the figure.

  • Corps (pos.6) with a lid (pos.1), equipped with special eyes (poses.5) through which the cutting cord is displayed;
  • Shpulya (pos.3), on which a fishing line for a trimmer is wound (pos.7);
  • A pressing spring (pos. 4).

There are other simpler heads.

What can be used instead of fishing line

Many users of trimmers are interested in the question: how can you replace the default cord used in this device? They begin to conduct dangerous experiments, installing a metal or copper wire, metal cables or strings, as well as a regular fishing line for a trimmer in a mowing head.

If a metal cable is installed instead of fishing line, then the trimmer for grass becomes a dangerous device not only for the user, but also for others. This fact is explained by the fact that during the operation of the unit, the steel cable will gradually work, its ends will be rash, and small pieces of wire will fly in different directions at high speed.

And if you accidentally touch your or someone else’s leg while working with a steel cable (wire), this will provide a strong and deep section of fabrics, and in some cases, amputation of the toes. It is not surprising that the manufacturer uses nylon for this purpose, since it is quite light and durable, and in the disconnected state it does not fly out and cannot cause injury.
