MAINTENANCE

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 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.

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.

Vibration damping system

Regularly check the vibration damping units for cracks or

deformation.

Make sure the vibration damping units are securely attached

to the engine unit and handle unit.
