Throttle Lockout - Husqvarna TrioBrake 345e EPA II Operator's Manual

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.

MAINTENANCE
• 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.
Chain catcher
Check that the chain catcher is not damaged and is firmly
attached to the body of the chain saw. Replace it if necessary
with an aluminium chain catcher (is available as spare part).
Right hand guard
Check that the right hand guard is not damaged and that there
are no visible defects, such as cracks.
