CLEAN AIR FILTER
A dirty air filter decreases the life and performance of the engine and in- creases fuel consumption and harmful 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. A used air filter can never be completely cleaned. It is advisable to replace your air filter with a new one after every 50 hours of operation, or annually, which- ever comes first. To clean filter:
1.Loosen and remove 3 screws from cylinder cover.
2.Remove cylinder cover.
3.Loosen and remove 2 screws from air filter.
4.Remove air filter.
5.Clean the air filter using hot soapy water. Rinse with clean cool water. Air dry completely before reinstalling.
