A well-sharpened chain is just as important as a powerful engine
We strongly recommend that you learn how to sharpen the saw chain yourself. The reason is that the chain must be kept sharp in order to cut efficiently, safely and with accuracy. Professional loggers sharpen their chains several times every working day, because they know that a sharp chain is just as important as a powerful engine.
How often should you sharpen the chain? That naturally depends on how much you use the saw, but when the chain starts to seem blunt it is usually time to sharpen it. The appearance of the chips gives a good indication of the chains condition. A sharp chain produces fine, regular wood chips, while a blunt chain just produces sawdust.
