/CC
_1 WARNING: Mufflersfitted 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!
_1_ 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 coefing
system for maintaining the right operating
temperature•
The cooling system consists of the follow-
ing components:
1. Air intake on the starter device (DD).
2. Fan blades on the flywheel (EE).
3. Cooling fins on the cylinder (FF).
4. Cylinder cowling (guides cooling a{r f_ow
aga{nst cylinder surfaces).
Ctean the coefing system by brushing once
a week, or more often, if necessary.
A dirty or b_ocked coefing system will
cause the b_ower to overheat and this will
damage the cytinder and piston

Air filter
The air filter (GG) must be regulady cleaned
to remove dust and dirt in order to avoid:
• Carburetor mallunctions
• Starting problems
• Loss of engine power
• Unnecessary wear to engine parts
• Excessivefuef consumption
• 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 fiEter cover (HH) and take out
the filter. Wash it clean in warm, soapy water•
Rinse thoroughly. Ensure that the _ter 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.
