How is the chainsaw sharpened?

Chainsaw - a useful tool for garden and forestry. The effectiveness of its work depends on the degree of wear and sharpness of the cutting elements. Sharpening chains chainsaw can be entrusted to a specialist. However, after having studied the necessary information on this issue and practicing a little, the newcomer will be able to perform this work independently .

How to determine that the saw needs sharpening?

The working surface of the chain saw chain consists of two types of links: cutting and limiting teeth. The former have a greater height than the latter. The difference in altitude is usually always at the same level - 0.5-0.8 mm. When it changes the efficiency of the saw's cutting is sharply reduced, it starts to lead to the side. The sawing time is increased. The need for sharpening can also be seen from the shape of the remaining chips. Sharp teeth create a uniform shavings. Its particles have a square shape. If the links are stacked, the shape and size of the particles will be different. From under the chain begins to pour small dust mixed with chips, outwardly reminiscent of needles. Working with such saws is not only uncomfortable, but also dangerous. Its continuation can lead to a breakdown of the mechanism and injury to a person. Therefore, in such cases, the chain saw chains should be immediately sharpened.

What tools will be needed?

Often professional woodcutters use machine tools. They are set special circles for sharpening chains chainsaw. A common gardener can do without buying expensive equipment. The chainsaw grinding set includes the following tools:

• Flat file,
• A file of cylindrical shape,
• Combined pattern,
• Vise (this tool will make it easier, but you can do without it).

Sharpening process

The pattern is superimposed on the chain so that the direction of the arrows coincides with the chain motion vector. The angle of the file should be selected for each chain individually, based on its step. Sharpening is made by easy precise movements towards the tire. Each tooth requires the same number of approaches. The cutting teeth are processed in two. The first - on the one hand, the second - on the other. Sharpening chains chainsaws on the pattern eliminates errors and helps to avoid vibration of the saw in the future. For flat teeth, a flat file is used. The template assumes two positions for different tree species: "H" (hard) for solid, "S" (soft) for soft.

Operation of the saw

If you follow the basic rules of use, sharpening chainsaw chain will be required much less often, and the device will last much longer. Never forget about the lubrication mechanism. The oil must always flow to the surface of the sprocket, chain and guide rail. During operation, it is necessary to monitor how the chain is stretched. Insufficient tension may result in slipping and may present a serious health hazard. Do not use a dull chain. Its application will lead to an excessive load on the saw mechanism and rapid wear of the parts.
