• Cooling fins on the cylinder
• Cylinder cover (directs cold air over
the cylinder)

overheating which causes damage to
the piston and cylinder.

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 completely
cleaned. It is advisable to replace your
air filter with a new one after every 50
hours of operation, or annually, which-
ever comes first.
