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

hours of operation, or annually, which-
ever comes first. To clean filter:
1. Loosen 3 screws on cylinder

water. Rinse with clean cool water.
