Sharpening a chainsaw chain with your own hands. features and methods
If the chainsaw has a dull chain, it reduces productivity. You put in a lot of effort but you don’t get a good cut. But the risk of injury increases greatly if you use a chain saw with a bad chain. There are several ways out of this situation. You can buy a new chain, have it sharpened at a special service center or do it yourself. In the latter case, sharpening the chain for a chainsaw will cost you for free.
If you are accustomed to long use of chain saws, intensive work with the tool, it means that you have faced the problem of sharpening the teeth of the chain. Once you hit a patch of sand or soil, the teeth of the chain become less sharp and the quality of cutting is impaired. If you give the saw to a sharpening machine every time, you have to take breaks in your work. It is much faster to learn how to sharpen the chain of a chainsaw correctly by yourself.
The complicated shape of the teeth makes sharpening your saw chain difficult, so before you start sharpening, you need to be familiar with the ways and fine points of sharpening your saw chain.
How a chain is sharpened on a chainsaw
The parts are the teeth and the connecting pieces. The teeth are along the entire chain and alternate in right-hand and left-hand turns. The links are made of a special steel material and the teeth have a hard chrome coating that increases their wear life.
STIHL has excelled in manufacturing quality products more than any other of its products, and the following are some of STIHL’s key strengths. STIHL chains are manufactured in Switzerland, with multiple testing and induction hardening to increase the wear resistance of the entire bearing surface.
So, the chain consists of these elements:
- drive links (1);
- The cutter bar itself also consists of the left hand saw chain and the left hand bar link (2);
- left-hand cutting teeth (3);
- The right cutting teeth (4);
- knurled drive links (5) for low kickback applications.
The cutting tooth itself is also made up of individual areas:
The special thing about the tooth is that it is not sharpened on one side but on several sides at the same time and is shaped in the process:
- angle for cutting the upper blade into the wood (1);
- rear angle of the end blade (2);
- front angle of nose blade (3); different chains 60-85 degrees;
- back angle of upper blade (4); the value varies from 50-60 degrees;
- sharpening angle (5); 25-35 degrees is optimal; the higher the angle. The softer the wood for sawing;
- depth stop distance (6);
- Tooth diagram (8).
Timely repair of the saw chain is advisable
Putting off repairing the chain indefinitely is highly undesirable. a saw chain with blunted cutting edges reduces the chainsaw’s cutting performance by about half, consumes less fuel and wastes valuable working time.
The problem is solved by taking it to a specialized repair shop, which inevitably leads to additional costs. In another variant owners of chainsaws practice sharpening the chain of a chainsaw with their own hands. There is no set maintenance interval for the saw chain.
Main rules and order of sharpening
Design and shape of the teeth
First of all, it is necessary to understand the structure of the chain tooth, which is subject to sharpening. The tooth slices through wood like a planer. It has a complex configuration and an unusual cutting surface with two cutting edges. one lateral and one slightly beveled on top. The tooth stop, whose height is variable, controls the thickness of the chip. Of course, sharpening these teeth is much harder than for example with a kitchen knife.
The chainsaw tooth is shaped in a more complex way than other sharp objects that need to be sharpened
The correct chain sharpening angle for a chainsaw chain should be established. It is clear that to act with one file is difficult, so there are various auxiliary devices that help to adhere to the exact parameters of sharpening. Such kits are sold as part of chainsaws, as well as separately.
The diagram shows the inclination angles to be observed during sharpening
When sharpening, the position of the tool should be correct. The choice of a round file is not accidental. it is the rounded shape of the inner contour of the tooth that is advantageous. the edge of the file should be 20% of its diameter above the cutting surface, and the choice of diameter is influenced by the length of the chain pitch (usually from 4 mm to 5.5 mm). Always follow the correct order: first you work on the cutting teeth, then on the stop tooth.
The question arises: how to sharpen the chain so that all teeth are uniformly flat and sharp? Work is made easier by using a metal block that is laid on the chain. It is set in a strict position. according to the arrows, the ends of which are directed by the chain movement. The main pressure is applied to the cutting edge, respecting the angle of inclination which is correlated with the pitch length of the chain.
Try to use an equal number of strokes per tooth. Sharpen the teeth one at a time: one on the left side, the next one on the right side, and so on. For ease of operation, the tire is clamped in a vise, and then machined through the tooth on one side, then the same on the other.

Grinding the Limiter
The work is regulated by the template, to the level of which the limiter tooth should be ground with a flat file instead of a round one. The jig position “S” is for soft wood, “H” for hard wood. If you do not use the template, you can get a wrong, low cut, from which the efficiency of the saw will decrease dramatically.

If the sharpening process requires that the chain be dismantled, do not force the threaded fastener when reinstalling it. An electric screwdriver calibrated to the dial is the best way to tighten the bar mount screws.
Experts recommend the method of increasing strength and wear resistance of chains, which is known as “stabilization of internal structure of metal”. To do it a new guide bar is warmed up in oil bath at temperature of 55-65°C for one and a half to two weeks. This has been proven in practice.
