Cleaning
1) Remove the air cleaner element. Refer to "Air
Cleaner Element Removal and Installation in Section
1D (Page 1D-7)".
2) Carefully use compressed air to clean the air cleaner
element.
CAUTION
!
Always apply compressed air to the inside of
the air cleaner element. If compressed air is
applied to the outside, dirt will be forced into
the pores of the air cleaner element,
restricting air flow through the air cleaner
element.
3) After cleaning the air cleaner element, reinstall the
removed parts.
4) Drain water from the air cleaner by removing the
drain plug.
5) Reinstall the drain plug.
