How to sharpen chain chainsaws: the features of the process

Harvesting firewood or even simple work in the garden, if it is performed using an electric or gasoline saw, requires a well-grounded chain. We think that it makes no sense to buy a new one every time, as its value can hardly be called moderate.

So how do you sharpen the chainsaw chains? Let's deal with the main points.

When is it necessary to sharpen?

How do you know that the cutting edge has lost its sharpness? Well, there are enough signs. To begin with, the tool begins to enter the tree with difficulty, and the sawing process itself is much slower. In addition, in this case the working tire of the tool begins to warm up a lot.

By the way, where to sharpen the chain for the chainsaw? This can be done both in your garage, and turn to professionals with a machine.

Pay attention to sawdust!

Experienced sawmillers know that the size of sawdust is very revealing: if they become like fine dust that occurs when working on a grinding machine, then the chain is 100% time to sharpen.

Since we can sharpen the chainsaw chains in two ways, we will immediately note that we will consider a manual procedure. It is unlikely that some summer resident will buy an automatic machine, the cost of which is comparable to the price of two peers of the amateur class.

Manual sharpening

Of course, the most popular is the manual type, since it does not require the purchase of a complex and expensive tool. That's only to approach this kind of sharpening should be the most accurate.

Just note that the height of the cutter, as well as the angle of the cutting tooth should strictly comply with the standards, which in the accompanying documents indicated the manufacturer. "Chemical" and "improve" does not need anything here. In no event can you change the links of the factory chains (even seemingly identical), since all this is fraught with their breaks.

Select file

Before you sharpen the chain chainsaw, you need to buy a special set. It's better when you constantly use tools from only one manufacturer. In this case it is better to buy a set for sharpening the same brand.

Carefully study the parameters of the tooth, its inclination and step! Suppose that the step, the most common, is 4-5.5 mm. Attach a file to the tooth: it should not extend over its upper edge more than 1/5 of the length. During grinding, you need to hold the file at an angle of 10-30 ° to the horizontal plane.

How is sharpening

Since it is not possible to quickly sharpen the chainsaw chains quickly, each movement should be done slowly and accurately. The file must be constantly rotated along its axis: this not only ensures the best grinding of the teeth, but also the tool itself wears more evenly.

Prevent the wear of the file

Do not "jump" from the tooth to the tooth, each of them must be sharpened consistently. It is preferable to sharpen the cutting edge first from one side, and then, after the complete passage of the chain, go over to the other. This approach is not only more convenient, but also completely prevents overheating of the metal.

In advance determine the same number of movements, which will sharpen the chain. This will prevent uneven tool wear. If there is an uneven wear of the teeth, you need to focus on the length of the shortest, shoving the rest to its size.

So we told how to sharpen the chain chainsaw.
