Chain - an important element of the chainsaw. And if the engine, even with mistreatment, does its work for tens of hours, then improper operation of the circuit will make it impossible to work after 10 minutes. So, learn to choose and care for the chain correctly.
Professionals know that it is not power that makes a saw a good tool, but a method of operation, handling it. And if the chainsaw is properly followed, it will last for decades and will always show excellent cutting qualities. If the tool is not properly handled, then even the newest saw, bought for huge money, does not want to work at all. And most importantly, on which the cutting qualities depend, this is related to the chain. It must be properly operated, constantly eroded, and, of course, correctly chosen.
