MAINTENANCE

Chain catcher

Check that the chain catcher is not damaged and is ﬁrmly attached to the body of the chain saw.

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.

Stop switch

Start the engine and make sure the engine stops when you move the stop switch to the stop setting.

CAUTION! The start/stop switch automatically returns to run position. In order to prevent unintentional starting, the spark plug cap must be removed from the spark plug when assembling, checking and/or performing maintenance.

Mufﬂer

Never use a machine that has a faulty mufﬂer.

Regularly check that the mufﬂer is securely attached to the machine.

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.
