•
Check that the throttle control and throttle lock move
freely and that the return springs work properly.
•
Start the chainsaw 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 chainsaw.
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.
Muffler
Never use a chainsaw that has a faulty muffler.
Regularly check that the muffler is securely attached to the
chainsaw.
Some mufflers are equipped with a special spark arrestor
mesh. If your chainsaw has this type of muffler, you should
clean the mesh at least once a week. This is best done with a
wire brush. Blocked mesh will cause the engine to overheat
and may lead to serious damage.
Never use a muffler if the spark arrestor mesh is missing or
defective.
The muffler is designed to reduce noise level and direct
exhaust gases away from the operator. Exhaust gases are
hot and can contain sparks, which may cause fire if directed
against dry and combustible material.
Starter
Changing a broken or worn starter cord
•
Loosen the screws that hold the starter against the
crankcase and remove the starter.
NOTE: The mesh must be replaced if it is damaged. If
the mesh is blocked, the chainsaw will overheat and
this will cause damage to the cylinder and piston.
Never use a chainsaw with a muffler that is in poor
condition.
