performance of the engine and in-

and harmful
emissions. Always clean your air filter
after 15 tanks of fuel or 5 hours of op-

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 3 screws on cylinder
cover

water. Rinse with clean cool water
