MAINTENANCE
Regularly check that the mufer is securely attached to
the machine.
Some mufers are equipped with a special spark arrestor
mesh. If your machine has this type of mufer, 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 mufer that is in poor condition. Never
use a mufer if the spark arrestor mesh is missing or
defective.
The mufer 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 re if directed against dry and combustible
material.
