Any owner who has a chainsaw in his possession sooner or later faces the fact that the chain loses its original sharpness. And here, many do not see another way out of the situation, how to get a new one. But the one who is used to tinkering 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 the chain of a chainsaw?" Let's figure out step by step how to do it right.
Stage 1
To get started, without removing the chain, determine its size. For sharpening, it is better to use a grindstone, which almost everyone has on the farm, and a file (special) for a chainsaw. To date, there are several sizes of chainsaws.
2 stage
Before sharpening the chainsaw chain, you must thoroughly clean it. To do this, you need to use any cleaner you have, such as acetone, gasoline, but white spirit is the best option. At the same time, you can also clean the chainsaw body, just be careful so that the product does not get into the engine.
3 stage
Before sharpening the chainsaw chain, inspect it for any damage. Pay special attention to the teeth. If some of them are bent or have chips and are very worn out, then it is better not to use such a chain. Lumberjacks have the following rule: in a chain suitable for operation, the shoulder blade of each tooth should be at least a quarter of an inch.
4th stage
Put the saw in a stable, reliable position, setting it on a hard, devoid of potholes and bevels, surface. Also, in some cases, you can use a vise. This must be done so that the chain remains movable and rotates freely.
5 stage
For the starting point, find the leading tool. As a rule, it is the shortest. If your chain has all the teeth the same, you can start from any. During a process such as sharpening a chain, it is necessary to file each cutter with a file so that all of its blades are 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 starting cutter with a marker or a dot of paint before starting.
6 stage
Before sharpening the chainsaw chain, inspect the file used for potholes. Then place it in the front notch of the incisor, which is an inclined prong, located on the flat surface of the link. It should be borne in mind that about 1/5 of the file when sharpening should protrude.
7 stage
Before sharpening the chain of the "Calm" chainsaw or another brand, correctly position the file on the surface of an individual link. The angle must be maintained within 25-30 degrees. These values are optimal.
8 stage
With moderate smooth movements, turning the file directly along the front 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 sharpen a chain of a chainsaw, and what you need to use for this.
