CLEAN AIR FILTER
CAUTION:
Do not clean filter in gasoline or
other flammable solvent to avoid creating a
fire hazard or producing harmful evaporative
emissions.
Cleaning the 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 10 tanks of fuel or 5
hours of operation, 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 fil-
ter with a new one after every 50 hours of op-
eration, 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 com-
pletely before reinstalling.
5. Reinstall air filter and air filter cover.
6. Reinstall cylinder cover and 3 screws.
