WARNING:
Mufflers fitted with
catalytic converters get very hot
during use and remain so for some
time after stopping. This also ap-
plies at idle speed. Contact can re-
sult in burns to the skin. Remember
the risk of fire!
WARNING:
Bear in mind that:
Engine exhaust fumes contain car-
bon monoxide, which can cause
carbon monoxide poisoning. For
this reason you should not start or
run the machine indoors, or any-
where that is poorly ventilated.
The exhaust fumes from the engine
are hot and may contain sparks
which can start a fire. Never start
the machine indoors or near flam-
mable material!
WARNING:
The inside of the
muffler contain chemicals that may
be carcinogenic. Avoid contact with
these elements in the event of a
damaged muffler.
Cooling system
The engine is equipped with a cooling
system for maintaining the right operating
temperature.
The cooling system consists of the follow-
ing components:
1. Air intake on the starter device (BB).
2. Fan blades on the flywheel (CC).
3. Cooling fins on the cylinder (DD).
4. Cylinder cowling (guides cooling air flow
against cylinder surfaces).
Clean the cooling system by brushing once
a week, or more often, if necessary.
A dirty or blocked cooling system will
cause the blower to overheat and this will
damage the cylinder and piston.

Air filter
The air filter (EE) must be regularly cleaned
to remove dust and dirt in order to avoid:
S Carburetor malfunctions
S Starting problems
S Loss of engine power
S Unnecessary wear to engine parts
S Excessive fuel consumption
S Elevated content of harmful exhaust
fumes.
Clean the filter every 25 hours, or more
regularly if conditions are exceptionally
dusty.
Cleaning the air filter
Remove the air filter cover (FF) and take out
the filter. Wash it clean in warm, soapy water.
Rinse thoroughly. Ensure that the filter is dry
before reinstalling it.
An air filter that has been in use for a long
time cannot be cleaned completely. The
filter must therefore be replaced with a new
one at regular intervals.
CAUTION! A damaged air filter must
always be replaced.
