IMPORTANT
Do not remove the secondary filter element
(J) unless it needs replacing. Do not
attempt to clean the secondary (inner)
element.
1. Hold a bright light inside primary element (H),
and check carefully for holes. Discard any
element that shows the slightest hole.
2. Be sure outer screen is not dented. Vibration
would quickly wear a hole in the filter.
3. Be sure filter gasket is in good condition. If
gasket is damaged or missing, replace
element.
4. If element is coated with oil or soot, replace
the element.
d. Inspect the air intake piping for damage, cracked
hoses, loose clamps, etc. Repair or replace
damaged parts, and tighten loose clamps.

If there is visible dirt on the secondary element,
replace both primary and secondary elements.
IMPORTANT
The air cleaner's primary (outer) filter
element should be replaced after six
cleanings, or at least every three years.
IMPORTANT
The secondary (inner) element should be
replaced every third time the primary
element is changed.
f. Clean inside of canister, and cover with a damp
cloth.
IMPORTANT
Leave secondary element in place to
prevent ingress of dirt into engine intake.

with compressed air.
i. Hold nozzle next to inner surface, and move up
and down pleats.
