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 and remove 3 screws from

cylinder cover.

2. Remove cylinder cover.
3. Loosen and remove 2 screws from

air filter.

4. Remove air filter.
5. Clean the air filter using hot soapy

water. Rinse with clean cool water.
Air dry completely before reinstalling.

6. Reinstall air filter and 2 screws.

Tighten screws securely.

7. Reinstall cylinder cover and 3

screws. Tighten screws securely.

engine performance. Replace the spark
arresting screen if breaks occur.
