MAINTENANCE
Vibration damping systemSome 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 Note! The mesh must be replaced if it is damaged. If the mesh
deformation.is blocked the machine will overheat and this will cause
damage to the cylinder and piston. Never use a machine with
a muf�er that is in poor condition. Never use a muf�er if the
spark arrestor mesh is missing or defective.
Make sure the vibration damping units are securely attached
to the engine unit and handle unit.
Stop switchThe muf�er is designed to reduce the noise level and to direct
the exhaust gases away from the operator. The exhaust gases
are hot and can contain sparks, which may cause Ţre if
directed against dry and combustible material.
Start the engine and make sure the engine stops when you
move the stop switch to the stop setting.Starter
WARNING! When the recoil spring is wound
up in the starter housing it is under tension
!and can, if handled carelessly, pop out and
cause personal injury.
Care must be exercised when replacing the
return spring or the starter cord. Wear
protective glasses and protective gloves.
Changing a broken or worn starter cord
Muf�er
Y Loosen the screws that hold the starter against the
crankcase and remove the starter.
Never use a machine that has a faulty muf�er.
Y Pull out the cord approx. 30 cm and hook it into the notch
in the rim of the pulley. Release the recoil spring by letting
the pulley rotate slowly backwards.
Regularly check that the muf�er is securely attached to the
machine.
