CLEAN AIR FILTER

A dirty air filter decreases the life and perfor-
mance of the engine and increases fuel con-
sumption and harmful emissions.
Always clean your air filter after 5 tanks of fuel
or 5 hours of operation, whichever comes
first. Clean more frequently in dusty condi-
tions. It is advisable to replace your air filter
with a new one after every 50 hours of opera-
tion, or annually, whichever comes first.
To clean filter:
1. Remove the two screws and the air filter
cover from the engine.
2. Remove air filter.
NOTE:
Do not clean the air filter with gaso-
line or other flammable solvent to avoid creat-
ing a fire hazard or producing harmful evapo-
rative emissions.
3. Wash the filter in soap and water.
4. Allow filter to dry.
5. Add 4 or 5 drops of oil to the filter.
NOTE:
Do not soak air filter with oil.
6. Squeeze the air filter to distribute oil.
7. Reinstall air filter in housing.
8. Reinstall air filter cover.
CAUTION:
Make sure air filter is fitted into
the corners of the housing to keep dust from
entering engine and causing engine damage.
