MAINTENANCE
English 31
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.
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.
Stop switch
Start the engine and make sure the engine stops when
you move the stop switch to the stop setting.
Muffler
Never use a machine that has a faulty muffler.
Regularly check that the muffler is securely attached to
the machine.
The muffler is designed to reduce the noise level and to
direct the exhaust gases away from the operator. The
exhaust gases are hot and can contain sparks, which may
cause fire if directed against dry and combustible
material.
