• 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
carburetor 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.

MAINTENANCE
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.
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.
Note! The screen must be replaced if it is damaged. If the
screen is blocked the machine will overheat and this will
cause damage to the cylinder and piston. Never use a
machine with a muffler that is in poor condition. Never use a
muffler if the spark arrestor screen is missing or
defective.
