INSPECT AND CLEAN UNIT AND
DECALS
S After each use, inspect complete unit
for loose or damaged parts. Clean the
unit and decals using a damp cloth
with a mild detergent.
S Wipe off unit with a clean dry cloth.
COOLING SYSTEM
To keep the working temperature as
low as possible the machine is
equipped with a cooling system.
The cooling system consists of:
S Air intake on the starter
S Air guide plate
S Fins on the flywheel
S Cooling fins on the cylinder
S Cylinder cover (directs cold air over
the cylinder)
Clean the cooling system with a brush
after each use, more often in demand-
ing conditions. A dirty or blocked cool-
ing system results in the machine
overheating which causes damage to
the piston and cylinder.
CHECK CHAIN BRAKE
See
CHAIN BRAKE
section.
CLEAN AIR FILTER
CAUTION: Do not clean filter in gaso-
line or other flammable solvent to
avoid creating a fire hazard or produc-
ing harmful evaporative emissions.
Cleaning the air filter:
A dirty air filter decreases the life and
performance of the engine and in-
creases fuel consumption and harmful
emissions. Always clean your air filter
after 10 tanks of fuel or 5 hours of op-
eration, whichever comes first. Clean
more frequently in dusty conditions.
A used air filter can never be com-
pletely cleaned. It is advisable to re-
place your air filter with a new one af-
ter every 50 hours of operation, or
annually, whichever comes first.
1. Loosen 3 screws on cylinder cover.
2. Remove cylinder cover.
3. Remove air filter cover and air filter.
4. Clean the air filter using hot soapy
water. Rinse with clean cool water.
Air dry completely before reinstalling.
