MAINTENANCE
Vibration damping system
Regularly check the vibration damping units for cracks or
deformation.
Make sure the vibration damping units are securely attached
to the engine unit and handle unit.
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.
A muffler equipped with a catalytic converter significantly
reduces the amount of hydrocarbons (HC), nitrogen oxides
(NO) and aldehydes in the exhaust fumes. Carbon monoxide
(CO), which is poisonous and odorless, is not however
reduced! Consequently, never work in an enclosed or badly
ventilated area. Good air circulation should always prevail
when working in snowy hollows, ravines or in confined
conditions.
