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.
Chain catcher
Check that the chain catcher is not damaged and is firmly
attached to the body of the chain saw. Replace it if
