emissions. Always clean your air filter
after 15 tanks of fuel or 5 hours of op-
eration, whichever comes first. Clean
more frequently in dusty conditions. It
is advisable to replace your air filter
with a new one after every 50 hours of
operation, or annually, whichever
comes first. To clean filter:
1. Loosen 3 screws on cylinder cover.
2. Remove cylinder cover.
3. Remove air filter.
4. Clean the air filter using hot soapy
water. Rinse with clean cool water.
Air dry completely before reinstal-
ling.

screws. Tighten securely.
