gent.

CLEAN AIR FILTER

ance and increases fuel consumption and
harmful emissions. Always clean after every
5 hours of operation.

keep dirt from falling into the carburetor
chamber when the cover is removed.
2. Remove parts as illustrated.
NOTE:
Do not clean filter in gasoline or other
flammable solvent to avoid creating a fire haz-
ard or producing harmful evaporative emis-
sions.
3. Wash the filter in soap and water.
