Chain catcher MAINTENANCE Stop switch Check that the chain catcher is not damaged and is firmly attached to the body of the chain saw. Start the engine and make sure the engine stops when you move the stop switch to the stop setting. Right hand guard Muffler Check that the right hand guard is not damaged and that there are no visible defects, such as cracks. Never use a machine that has a faulty muffler. Vibration damping system Regularly check that the muffler is securely attached to the machine. 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. Some mufflers are equipped with a special spark arrestor screen. If your machine has this type of muffler, you should clean the screen at least once a week. This is best done with a wire brush. A blocked screen will cause the engine to overheat and may lead to serious damage. 32 - English
