7.8.5.2 Filter Element Cleaning
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:
a. Remove primary filter as described in previous
section.
b. Inspect as follows:
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.
5. Check the safety element for cleanliness. If
there is visible dirt on the safety element,
replace both primary and safety elements.
IMPORTANT
The air cleaner's primary (outer) filter
element should be replaced after three
cleanings or at the specified interval.
Refer to Section 7.13 MAINTENANCE
SCHEDULE.
IMPORTANT
The safety (inner) element should be
replaced every third time the primary
element is changed.
c. Clean element with compressed air, and a Dry
Element Cleaner Gun.
d. Hold nozzle next to inner surface, and move up
and down on pleats.
IMPORTANT
Air pressure must not exceed 60 psi
(400 kPa). Do not direct air against
outside of element, as dirt might be forced
through to inside.
e. Repeat inspection before installing.
