8. Maintenance
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. On
mufflers without a catalytic converter the mesh should be cleaned
weekly, or replaced if necessary. On mufflers fitted with a catalytic
converter the mesh should be checked, and if necessary cleaned,
monthly. If the mesh is damaged it should be replaced. If the
mesh is frequently blocked, this can be a sign that the
performance of the catalytic converter is impaired. Contact your
dealer to inspect the muffler. A blocked mesh will cause the
machine to overheat and result in damage to the cylinder and
piston.
CAUTION! Never use a machine with a defective muffler.
WARNING
• Mufflers fitted with catalytic converters get very hot during
use and remain so for some time after stopping. This also
applies at idle speed. Contact can result in burns to the
skin.
• Remember the risk of fire!
■ Cooling system
To keep the working temperature as low as possible the machine
is equipped with a cooling system.

The cooling system consists of:
1. Air intake on the starter.
2. Cooling fins on the cylinder.
3. Cylinder cover (directs cold air over the cylinder).
Clean the cooling system with a brush once a week, more often in
demanding conditions. A dirty or blocked cooling system results in
the machine overheating which causes damage to the piston and
cylinder.
■ Bevel gear
The bevel gear is filled with the right amount of grease at the
factory. However, before using the machine you should check that
the bevel gear is filled 3/4 full with grease.
The grease in the bevel gear does not normally need to be
changed except if repairs are carried out.
■ Air filter
The air filter must be regularly cleaned to remove dust and dirt in
order to avoid:
• Carburettor malfunctions
• Starting problems
• Loss of engine power
• Unnecessary wear to engine parts.
• Excessive fuel consumption.
Clean the filter every 25 hours, or more regularly if conditions are
exceptionally dusty.
