CAUTION:
ECA4S81008
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 
throttle bodies synchronization, leading to 
poor engine performance and possible 
overheating.
NOTE:
When installing the air filter element into the air 
filter case cover, make sure their sealing sur-
faces are aligned to prevent any air leaks.
