How to Wind a Fishing Line On a Bosch Trimmer

The speed of the electric and lawn mowers is largely affected by the quality of the fishing line. The consumption of the cord itself, as well as the load that affects the engine, depends on how correctly it is wound on the mower coil. In this regard, each gardener needs to carefully study the rules for the selection and self-installation of fishing line on a reel. This will prevent premature breakage of the spit and make its operation on the garden plot more convenient and efficient.

Which fishing line for trimmer is better?

When choosing a fishing line you need to consider several of its parameters.

The list of the main characteristics of the cutting cord includes:

  • fishing line thickness. the most common threads on the market are threads whose thickness is in the range 1.2–4 mm. A thin cord, with a thickness of not more than 1.6 mm, is intended for trimmers whose power does not exceed 0.8 l. from. Most often, this cord is used in cases where the farm has a low-power electric scythe with fishing line and knife. Cords with a diameter of up to 2 mm to 2.6 mm are used for trimmers with a capacity of 1 to 1.8 liters. from. These fishing lines are able to successfully remove not only freshly grown, but also quite old dried vegetation. Thick fishing lines, with a diameter of 3 mm or more, are intended for use with petrol scythes with a capacity of at least 3 liters. from. Cord with this thickness shows itself well when mowing large and dense wild vegetation;

  • trimmer cord shape. a lot depends on this factor, since when mowing grass, the thread does not cut the stems, but repeatedly hits them. It is the shape of the thread that affects the speed of mowing the grass and the accuracy of the cut line. Most often in the market you can find round fishing lines. This cord is suitable for mowing any kind of vegetation. A little less often on the market there is a square thread. It copes best with the removal of large hard stems, and is often used to mow wild shrubs. There is also a fishing line star on the market. It stands out for its low morbidity for grass, so it is best used for caring for decorative natural lawns;
  • material. In most cases, manufacturers use nylon, polypropylene and polyamide to produce cutting cord. Cheaper trimmer cords are made of nylon with polyethylene additives, which significantly reduces the resistance of the thread to wear and temperature.

Also, when choosing a cord, you need to take into account the type of equipment that will be used to work on the site. If the farm uses electric trimmers with fishing line and knife, then it is best to equip them with thin round cords that create a minimum load on the electric motor. If a powerful brushcutter is used to care for the site, then to work with it you can confidently use a thread with any thickness and cross section, including home-made fishing lines from a plastic bottle. The load on the gasoline engine, in these cases, will be almost imperceptible.

  2. Then, at one end of the first segment, you will need to make a kind of hook, and insert it into one of the through holes located in the upper part of the spool;
  3. Next, you need to start winding the fishing line on the spool in the direction indicated by the arrow. During winding, you need to make sure that the fishing line evenly lies on the surface of the spool, and does not go beyond its upper section. It is not necessary to wind up the segment to the end, about 15 cm of thread should remain in the hands;
  4. The remaining free end of the wound cord will need to be inserted into one of the recesses located in the upper part of the spool;

  3. After that, you need to start winding the fishing line. This must be done in the direction of the arrow indicated on the bobbin case. During winding, the cord should not be entangled. The upper part of the segment should be carefully wound on the upper, and the lower. on the lower section of the spool. After this, two 15-centimeter segments of the cord should remain free;

  • Then you need to start winding the fishing line. During installation, the line should not bend or hang. Otherwise, it will constantly jump out of the coil;
  • After winding the cord in the hands of the operator, there must be 2 ends, 10-15 cm long;
  • These ends must be threaded through holes located in the side walls of the upper part of the coil, opposite each other;
  • After that, you need to assemble the coil. At the same time, its spring should precisely stand between two metal washers.

The finished single-section coil will need to be installed on the household trimmer, after which it will be possible to continue mowing vegetation on the site.
