Keep tapping until no dust comes off. The element should
be replaced if the dust does not drop off easily or if the eleĆ
ment becomes bent or crushed.
Note: Do not wash elements in any liquid of blow dirt off
with air. Do not tap element on a sharp corner, it may damĆ
age the seal.

sene or liquid detergent and water to remove the dirt. Wrap
the foam in a cloth and squeeze dry. Saturate the foam in
engine oil and squeeze it to remove excess oil. Assemble
the parts and reinstall air cleaner to engine.

inefficient operation. Remove and clean spark plug as necessary (see

be between the FULL" and ADD" marks on the dipstick or to overflow

twenty-five (25) hours thereafter or at the end of each season. To
