Make sure the front hand guard is not damaged and that there are no visible defects such as cracks.
Move the front hand guard forwards and back to make sure it moves freely and that it is securely anchored to the clutch cover.
Checking the inertia brake release
With the engine turned off, hold the chain saw over a stump or other firm object. Let go of the front handle so that the bar drops towards the stump as the chain saw rotates around the rear handle.
When the bar hits the stump the brake should be applied.
