MAINTENANCE
� Check that the throttle control and throttle lock move freely and that the return springs work properly.
Stop switch
Start the engine and make sure the engine stops when you move the stop switch to the stop setting.
�
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 �rmly attached to the body of the chain saw.
Muf�er
Never use a machine that has a faulty muf�er.
Right hand guard
Check that the right hand guard is not damaged and that there are no visible defects, such as cracks. Regularly check that the muf�er is securely attached to the machine.
Vibration damping system
Some muf�ers are equipped with a special spark arrestor mesh. If your machine has this type of muf�er, you should clean the mesh at least once a week. This is best done with a wire brush. A blocked mesh will cause the engine to overheat and may lead to serious damage.
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.
