IMPORTANT

Air filter element cleaning is not
recommended due to the possible
degradation of the element material. If
cleaning is performed, there are several
risks involved, and the following
procedures should be followed:

1. Hold a bright light inside element and check

carefully for holes. Discard any element
which 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.

f.

Inspect the air intake piping for damage, cracked
hoses, loose clamps, etc. Repair or replace
damaged parts and tighten loose clamps.

IMPORTANT

Do not remove the secondary filter
element (K) unless it needs replacing. Do
not attempt to clean the secondary (inner)
element.

cleanliness. If there is visible dirt on the
secondary element, replace both primary and
