MAINTENANCE
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.
Checking the brake trigger
Place the chain saw on firm ground and start it. Make sure the chain does not touch the ground or any other object. See the instructions under the heading Start and stop.
Grasp the chain saw firmly, wrapping your fingers and thumbs around the handles.
Apply full throttle and activate the chain brake by tilting your left wrist forward onto the front hand guard. Do not let go of the front handle. The chain should stop immediately.
Throttle lockout
•Make sure the throttle control is locked at the idle setting when the throttle lockout is released.
•Press the throttle lockout and make sure it returns to its original position when you release it.
•Check that the throttle control and throttle lockout move freely and that the return springs work properly.
•Start the chain saw and apply full throttle. Release the throttle control and check that the chain stops and remains stationary. If the chain rotates when the throttle control is in the idle position you should check the carburetor idle adjustment.
