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
mesh. If your machine has this type of muffler, 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.
Note! The mesh must be replaced if it is damaged. If the mesh
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 mesh is missing or defective.
The muffler 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 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.
• 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.
!
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.
