912. Install the air filter case cover by hooking the
holders onto the cover. NOTICE: Make sure
that the air filter element is properly seated
in the air filter case. Never operate the en-
gine with the air filter element removed.
Doing so would allow unfiltered air to enter

possible engine damage. Additionally, the
fuel injection system would be affected re-
sulting in poor engine performance and
possible overheating.
