3. Wash the foam element in warm water with
detergent. Rinse the element thoroughly until all
traces of detergent are eliminated. Squeeze out all
excess water (do not wring). Allow the element to

Squeeze the precleaner to evenly distribute the oil
and remove any excess.

clean and check the air cleaner case and outer
cover for damage, distortion, or an improper
seal. Replace any components which are bent or
damaged.
6. Install the element into the air cleaner base.
7. Reinstall the cover and secure with the screw.
NOTE: Do not operate engine without the air cleaner
element; excessive piston and/or cylinder
wear may result.
