Chainsaw Chain Won't Move? Diagnose It Powered Down

If the chainsaw motor runs but the chain won’t move, stop applying throttle and switch the saw off. After disabling its power source exactly as the operator manual directs, use the chain’s hand-movement result to separate a brake, tension, installation, or debris problem from a clutch or drive fault that needs service. This article is for a motor that runs while the chain remains stationary. If the motor will not start, cannot accelerate, or dies when you press the throttle, that is a different diagnostic job. Do not keep revving against a chain that is locked: the useful evidence comes from a cooled, disabled saw.

Chainsaw Still Dull After Sharpening? Diagnose the Chain Before Filing Again

A chainsaw that is still dull after sharpening usually has a cutting edge that was not fully restored, depth gauges that no longer match the shortened cutters, or inconsistent cutter geometry around the loop. Do not start another full sharpening pass until you know which fault you are correcting. This guide is for homeowners, firewood cutters, and workshop users who have just filed or ground a chain but still need to push the saw through clean wood. Put the saw aside, clean the chain enough to see bare metal, and work through the checks in order.
