The chiansaw - the most useful tool for garden andlogging management. The effectiveness of its work depends on the degree of wear and sharpness of the cutting elements. Chain sharpening chainsaws may be assigned to a specialist. However, having studied the necessary information on this issue and having practiced a little, the beginner can independently perform this work.
How to determine that the saw needs sharpening?
The working surface of the chainsaw chain is twotype of links: cutting and limiting teeth. The first have a greater height than the second. The difference in height is usually always on the same level - 0.5-0.8 mm. When it changes the efficiency of the saw is sharply reduced, it begins to lead to the side. Sawing time is extended. The need for sharpening can also be seen in the form of the remaining chips. Sharp teeth create uniform chips. Its particles are square. If the links are stowed, then the shape and size of the particles will be different. From under the chain, fine dust mixed with chips that look like needles will begin to fall. Work with such saws becomes not only inconvenient, but also dangerous. Its continuation can lead to breakage of the mechanism and personal injury. Therefore, in such cases, sharpening the chainsaw chain should be immediately organized.
What tools are needed?
Often professional loggers use machine tools.They set special circles for sharpening chainsaw chains. An ordinary gardener can easily do without buying expensive equipment. The kit for sharpening the chainsaw chain includes the following tools:
- flat file
- cylindrical file
- combo pattern
- vice (this tool will facilitate the work, but without it it is quite possible to do).
Sharpening process
A pattern is superimposed on the chain so thatthe direction of the arrows coincided with the motion vector of the chain. The file angle should be selected for each chain individually, based on its pitch. Sharpening is done with light, 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 the chainsaw chain pattern eliminates errors and helps to avoid saw vibration in the future. A flat file is used for stop teeth. The template assumes two positions for different tree species: “H” (hard) for hard, “S” (soft) for soft.
Saw operation
If you follow the basic rules of use,then sharpening the chainsaw chain will be required much less frequently, and the device will last much longer. Never forget the lubrication mechanism. Oil should flow continuously to the surface of the sprocket, chain and guide rail. During operation, care must be taken how the chain is tensioned. Lack of tension threatens to slip and can be a serious health hazard. Do not use a dull chain. Its use will lead to excessive load on the saw mechanism and rapid wear of parts.
