MAINTENANCE

Checking the right-hand brake trigger

Check that the right hand guard is not damaged and that there are no visible defects, such as cracks.

Push the trigger up and forwards to check that it moves freely and is securely hinged to the clutch cover.

Never carry or hang the saw by the trigger! This could damage the mechanism and disable the chain brake.

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 carburettor idle adjustment.
