Basic Chain Maintenance

Besides maintenance for the engine or batteries, all chainsaws need some general care to keep their actual chains cutting like new. You’ll want to check the chain’s tension frequently, and sharpen or replace the chain when it becomes too dull. If you don’t, the machine’s performance will begin to suffer.

Try not to saw into the ground, as this can rapidly dull the blades! You’ll also need to keep the chain lubricated (this oil is in a separate reserve from the fuel). For pruning purposes, you might try a vegetable oil-based chain lubricant that is healthy for living trees.
