1. Unsnap the air cleaner cover and remove the elements.
2. Clean the elements:
FOAM PRE-CLEANER ELEMENT: Wash the foam pre-cleaner
element in warm water with detergent. Rinse the foam pre-
cleaner element thoroughly until all traces of detergent are
eliminated. Squeeze out excess water, but do not wring. Allow
the foam pre-cleaner element to air dry.
Saturate the foam pre-cleaner element with new engine oil.
Squeeze out all excess oil. DO NOT put engine oil on the foam
damper.
NOTE: Clean the foam pre-cleaner element every 25 hours of operation
(more often under extremely dusty or dirty condition)

ment or use pressurized air, as this will damage the element.
Clean by gently tapping the element to remove dust. Replace
the element if damaged, bent or extremely dirty. Handle new
element carefully; do not use if the sealing surfaces are bent or
damaged.

extremely dusty conditions.)

cleaner element. Close air cleaner cover and clasp shut.
