MAINTENANCE
Muffler
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.
!
CAUTION! Some mufflers are fitted with a catalytic
converter. See chapter on Technical data to see whether
your machine is fitted with a catalytic converter.
Remember the risk of fire!
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.
Cooling system
To keep the working temperature as low as possible the
machine is equipped with a cooling system.

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.
The cooling system consists of:

Air intake on the starter.
Fins on the flywheel.
Cooling fins on the cylinder.
Cylinder cover (directs cold air over the cylinder).
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. See also instructions
under the heading Maintenance.
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.
