CLEAN AIR FILTER
A dirty air filter decreases the life and
performance of the engine and in-

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 3 screws on cylinder cover.

water. Rinse with clean cool water.
Air dry completely before reinstal-
ling.

(SAE 30). Squeeze excess oil from
