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 lock

•Make sure the throttle control is locked at the idle setting when the throttle lock is released.

•Press the throttle lock and make sure it returns to its original position when you release it.

•Check that the throttle control and throttle lock 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 carburettor idle adjustment.
