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.
