How to Use a Stihl Trimmer Coil

How to Use a Stihl Trimmer Coil

The trimmer reel mows the grass, but it wears out and often needs to be replaced. Recently, motorcycle or electric scythes have become widespread. The main working element of such a garden tool are reels with fishing line tucked inside. Therefore, it is extremely important to choose a quality element so as not to waste money, because the device is quite expensive. To reduce the cost of servicing lawn mowers, you can learn how to independently feed the forest into the trimmer coil.

Often, manufacturers of power tools do not complete their products with a number of necessary or useful devices for operation, offering to purchase them separately (as an additional option). With the coil for lawn mowing, the situation is different: since this is the main working element of the garden tool, all trimmers are supplied with it, however, the quality of the coil from the braid kit leaves much to be desired.

The consumer has to purchase a coil separately. This is done to increase sales and make additional profit for manufacturers.

Below are questions about what a trimmer is, what kind of coils are there and how to independently insert and secure the fishing line.

What is a trimmer

Under the trimmer mean lawn mowers or electric braids. In fact, this is one of the types of lawn mowers (hand mowers) that are designed for mowing grass. This is a modern braid. Initially, they were designed to perform agricultural work, but the main use of trimmers was precisely mowing the lawns.

For the first time, the idea to create a trimmer came to the mind of an American entrepreneur J. Bollas. Driving in a car through an automatic car wash, he noticed that the principle of rotating brushes can be used to mow crops.

After that, he assembled a primitive trimmer from a can (as a reel) and fishing line threaded through holes drilled in it. He installed the resulting structure on a pole, on which the engine from a moped was previously mounted. The device mowed not only wheat, but also grass. Realizing that he would earn a lot of money by selling braids, the entrepreneur improved his product and gave it the name “Weed Shredder”. A feature of the invention was the possibility of grass mowing around trees. Forests perfectly cut grass, but did not injure the bark.

The main purpose of such a tool was grass mowing in small areas in places where classic wheeled vehicles cannot be used:

  • In the presence of a large number of shrubs;
  • In gardens with lots of trees;
  • Near fences and fences;
  • If the site has an uneven terrain.

All trimmers incorporate a bar. The main structural element. A gasoline or electric engine is attached to the rod from one end, and a reel with fishing line is put on the other. The main working element. Over, the type of transmission can be any. It is limited only by the capabilities of the manufacturer and commercial parameters.

Why this tool is called differently

The trimmer was originally understood as a manual lawn mower with an electric motor. At the same time, the power of the mower went both from the mains and from the battery, which can be installed on the bar or carried in a special pouch.

The main cutting element is the fishing line, which creates some restrictions on the type of grass being treated: only plants with a thin and soft stem can be mowed. The mowing area is limited by the cable length or battery capacity. However, recently braids with gasoline engines began to be called trimmers. They give greater mobility to the worker, which can significantly increase the size of the site.

But electric and gasoline braids were originally varieties of lawn mowers, however, with the advent of the trimmer, these designs have ceased to be in demand and are now rarely produced, and their names have passed to trimmers. Most people are more accustomed to call this tool.

Coil specifics

In the modern world (both in the city and in the village) it is practically impossible to do without such a modern and useful tool as a trimmer. It is widely used by public utilities of large cities, such devices are also in demand on farms, they are used to improve summer cottages, gardens, gardens, etc.

However, it should be remembered that the main working element is the head for the trimmer. A reel with fishing line. It is this element that most often fails and requires care. The price of the coils has a wide range (from 10 to 150 dollars), which makes such a tool even more expensive. Any manufacturer (even branded) completes its product usually with an inexpensive and low-quality coil. However, you can work for a long enough time and a primitive coil, provided that timely work to care for it.

Like any other mechanical element, the coil requires cleaning from the accumulated grass, cooling during overheating and filling the lubricant. However, coils often fail for various reasons, and buying new ones or carrying broken ones for repair is quite expensive. In this case, almost all malfunctions can be eliminated independently. It is not difficult to disassemble the coil, especially if you use the instructions.

The first part that often fails on the trimmer coil is the fishing line. Fishing line is a consumable for which the manufacturer is not responsible. At the same time, on many reel models, replacing the fishing line is a difficult procedure (and impossible for some brands). An attempt to replace the fishing line with a material different from the parameters of the native fishing line can lead to the destruction of the reel.

The reel itself (the part of the element onto which the fishing line is wound) rarely fails, while the grooves through which the working part of the fishing line is held and which hold it can collapse (grind off), since they are almost always made of plastic.

Despite the abundance of spare parts for trimmers on sale, not everyone can afford to purchase them, in addition, often there are restrictions on available products. For example, manufacturers make an “individual” mount for the trimmer, a universal coil for such a mount does not fit. This often makes it impossible to purchase a suitable coil price. Some manufacturers make reels designed for thin fishing line (up to 3 mm in diameter), which significantly limits the capabilities of the trimmer. Therefore, there is an option for self-manufacturing coils.

How to make a coil yourself

The basis of a homemade coil is a disk made of durable material. It is best used for these purposes textolite about 5 mm thick. It is strong enough and reliable. The size of the disk depends on the dimensions of the trimmer and personal experience. How to work more conveniently.

Next, drill a hole in the center of the disc. The diameter of the hole should be equal to the diameter of the axis of the rod (the latter is attached to the rotating shaft of the engine). It is extremely important to determine exactly the center of the disk. After that, you should drill 4 holes under the fishing line. Their diameter will be equal to the diameter of the fishing line, and they will be arranged in pairs on opposite sides of the axis (2 on one side, 2 on the other from the axis of rotation). In this case, the design of the reel is greatly simplified: it is not necessary to wind a large number of fishing lines, but rather fasten (tie) a small segment of it through the finished holes.

To give the structure the desired strength and reliability, it is recommended to find a spring whose inner diameter will be equal to the diameter of the shaft, and install it on the shaft on top of the finished disk.

Once the fishing line is tucked in and secured to the disc, you can begin the tests. You can not fix the fishing line on the disk motionlessly: even threaded into the holes, it will not fall out, because the engine gives high speeds to the shaft, and centrifugal force is enough to keep the fishing line under load.

This design, instead of the purchase coil for the trimmer, has many advantages: any fishing line (either thin or thick) can be installed in it, the device itself is practically “unkillable”, and it will not take a long time to purchase a new coil.

The disadvantages of this homemade product include the following:

  • The need to cut a pair of pieces of fishing line of the same length;
  • When installing without attaching fishing line, it is necessary to ensure that equal sections of fishing line hang from the reel.

The case can be used from an old coil. It rarely breaks.

Conclusion

Such a home-made coil can significantly reduce the cost of operating the trimmer, which improves its operating parameters. You can use the same trimmer for mowing both small shrubs and soft and thin lawn grass.
