UNIT & LABELS
• Clean the unit using a damp cloth
with a mild detergent.

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:
• Loosen 3 screws on cylinder cover.
• Remove cylinder cover.
• Remove air filter.
• Clean the air filter using hot soapy
water. Rinse with clean cool water.
Air dry completely before reinstalling.
• Lightly oil air filter before installing to
improve the efficiency of air filter.
Use 2-cycle engine oil or motor oil
(SAE 30). Squeeze excess oil from
filter.
• Reinstall air filter.
• Reinstall cylinder cover and 3 screws
(15-20 in-lbs.).
