Any owner who owns a chainsaw sooner or later faces the fact that the chain loses its original sharpness. And here, many see no other way out of the situation, how to purchase a new one. But the one who is used to doing everything with his own hands and does not like to spend money on what he can do himself, begins to look for the answer to the question: "How to sharpen a chainsaw chain?" Let's figure out step by step how to do it right.
1 stage
First, without removing the chain, determine its size. For sharpening, it is better to use a whetstone, which almost everyone has on the farm, and a file (special) for a chainsaw. Today, there are several sizes of chainsaw teeth.
2 stage
Before sharpening the chainsaw chain, it must be thoroughly cleaned. To do this, you need to use any cleaner you have, such as acetone, gasoline, butthe best option would be white spirit. At the same time, you can clean the body of the chainsaw, just be careful not to get the product into the engine.
3 stage
Before you sharpen your chainsaw chain, inspect it for any damage. Pay special attention to the teeth. If some of them are bent or chipped and worn out, then it is better not to use such a chain anymore. Professional lumberjacks have the following rule: in a chain suitable for work, the blade of each tooth should be at least a quarter of an inch.
4 stage
Place the saw in a stable, secure position by placing it on a hard, dent-free and bevel-free surface. Also, in some cases, you can use a vice. This must be done so that the chain remains movable and rotates freely.
5 stage
Find the lead cutter as a starting point. As a rule, it is the shortest. If your chain has all the same teeth, you can start with any. During a process such as chain sharpening, it is necessary to file each cutter so that all of its blades are the same size. Only in this case will they evenly cut off the layer of wood and form the correct cut. If all the teeth are the same, it is better to mark the starting cutter with a marker or a dot of paint before starting.
6 stage
Before sharpening the chainsaw chain, inspect the file used for gouges. Then place itinto the front notch of the cutter, which is an inclined tooth located on the flat surface of the link. It should be borne in mind that about 1/5 of the file should protrude when sharpening.
7 stage
Before sharpening the chain of a Stihl or other brand of chainsaw, correctly position the file on the surface of a single link. In this case, the angle must be maintained within 25-30 degrees. These values are optimal.
8 stage
With moderate smooth movements, rotating the file directly on the face of the cutter, sharpen the chain. At the same time, remove metal chips in a timely manner. Thus, process the tooth through one, and then repeat the same manipulations in the opposite direction.
Now you have learned how to properly sharpen a chainsaw chain, and what you need to use for this.
