Never operate the engine without the air
filter element installed. Unfiltered air will
cause rapid wear of engine parts and may
damage the engine. Operating the engine
without the air filter element will also
affect carburetor tuning, leading to poor
engine performance and possible over-
heating.
NOTE:
When installing the air filter element into the
air filter case cover, make sure that the seal-
ing surfaces are aligned to prevent any air
leaks.
