A chainsaw is a portable mechanical, motorized saw. Chain Saws if used continuously becomes dull and needs to be sharpened to cut quickly. A sharpened chainsaw significantly cuts the time and energy. Chains must be kept very sharp to perform well. This may be done with a round file or a jig (without removing the chain from the saw), or with a specialized electric sharpening jig with the chain removed from the saw. The jigs help ensure that each cutting face is kept at the correct angles, which are carefully balanced to maximize the saw's efficiency. Proper hand-sharpening may produce a better result, but electric sharpeners are faster, particularly when sharpening very dull chains. Carbide chainsaw blades cannot be sharpened by conventional sharpeners and must be sharpened by a diamond sharpener.
What You Need
Chainsaw Sharpening Attachment
Begin on the near side teeth, keeping the line on the guide parallel to the chain. A few light strokes on each tooth are enough.
Now sharpen the far side, keeping the back edge of the guide parallel to the chain. The same number of strokes should be done to each tooth to keep it balanced.
After completing the top bar, advance the chain with a gloved hand.
You'll notice the newly sharp edges immediately.
