To begin with, without removing the chain, determine its size. For grinding it is better to use grindstone, which is in the household for almost everyone, and a file (special) for the chainsaw. To date, there are several sizes of chainsaw teeth.

Before you sharpen the chainsaw chain, you must thoroughly clean it. To do this, you need to apply any available cleaner you have, such as acetone, gasoline, but the best option is white spirit. At the same time, you can clean the body of the chainsaw, just be careful that the product does not get into the engine.

Stage 3

Before sharpening the chainsaw chain, inspect it for no damage. Pay special attention to the teeth. If some of them are bent or are chipped and badly worn, then it is better not to use such a chain anymore. The professional woodcutters have the following rule: in a suitable chain, the blade of each tooth must be at least a quarter of an inch.

4 stage

Put the saw in a stable, secure position, setting it on a solid, devoid of potholes and bevels, the surface. In some cases, you can also use a vice. It must be done so that the chain remains mobile and free to rotate.

5 th stage

For the starting point, find the leading edge. As a rule, it is the shortest. If your chain has all the same teeth, you can start from anyone. During the process, such as sharpening the chain, it is necessary to process each cutter with a file in such a way that all of its blades have the same size. Only in this case they will evenly cut the layer of wood and form the correct cut. If all the teeth are the same, it is better to mark the start tool with a marker or a paint point.

Before you sharpen the chain saw chains, inspect the file used for the absence of potholes. Then place it in the front notch of the tool, which is an inclined denticle, located on the flat surface of the link. It should be taken into account that about 1/5 of the file when sharpening should act.

7th stage

Before you sharpen the chainsaw chain "Calm" or another brand, place the file correctly on the surface of a separate link. The angle must be maintained within 25-30 degrees. These values are optimal.

8th stage

Moderate smooth movements, rotating the file directly on the face of the tool, make the chain sharp. In this case, remove the metal shavings in a timely manner. Thus, treat the tooth through one, and then repeat the same manipulations in the opposite direction.

Now you have learned how to properly sharpen the chainsaw chain, and what you need to use for this.
