Never operate the engine without the air fil-
ter 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 synchronization, leading to poor
engine performance and possible overheat-
ing.
TIP
When installing the air filter element into the air
filter case cover, make sure that the sealing
surfaces are aligned to prevent any air leaks.
