c. Remove the wing bolt. Pull the element out of the air-
cleaner.
d. Dust it off by patting lightly while holding it with the
other hand.
e. When the element does not become clean only by
patting, blow dust off the element with compressed
air. Apply compressed air from inside to outside of the
element.
f. When the element does not become sufficiently clean
only by blowing, dip it in neutral detergent solution
for about 30 minutes and then rinse it in fresh water.
Then dry it in the atmospheric temperature.
g. After cleaning, install the element in reverse order of
disassembly.
IMPORTANT: • Never hit the element against a hard ob-
ject like a concrete wall.
• An element which is damaged should be
replaced with a new one.
• Never attempt to start the engine without
the air-cleaner element. Such operation
will cause engine trouble.
