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 3 screws on cylinder cover.
2. Remove
cylinder cover.
3.
Remove
air filter.
4.
Clean the air filter using hot soapy
water. Rinse with clean cool water.
Air dry completely
before reinstalling.
5. 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.
6.
Reinstall air filter.
7.
Reinstall cylinder cover and 3
screws. Tighten securely.
