MAINTENANCE AND SERVICING
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. If any of
the following conditions are found, the filter element MUST be replaced.
1. Hold a bright light inside element, and check carefully for holes.
2. Check outer screen for dents. Vibration would quickly wear a hole in the filter.
3. Check filter gasket for cracks, tears, or other signs of damage.
4. Check element for oil or soot contamination.
5. Check the secondary element for cleanliness. If there is visible dirt on the secondary element, replace both
primary and secondary elements. Do NOT clean.
IMPORTANT:
The air cleaner’s primary (outer) filter element should be replaced after three cleanings or at the specified interval.
The secondary (inner) element should be replaced every third time the primary element is changed. Refer to
5.7.11
Maintenance Schedule, page 407 for the required interval.
6. If secondary element passes inspection, clean primary element as follows:
a. Use compressed air NOT exceeding 60 psi (400 kPa), and a Dry Element Cleaner Gun.
b. Hold nozzle next to inner surface only, and move up and down on pleats.
c. After three cleaning’s (or at the specified interval), replace the primary element.
7. Repeat inspection before installing.
Removing and Installing Secondary Air Filter
Replace the secondary air filter (A) every year or after every
third primary filter change (even if it appears clean).
If you’re changing the secondary air filter because it is dirty,
inspect the primary filter and the filter canister to determine
the reason for contamination.
• Examine the filter canister for cracks and replace if
necessary.
• Ensure filter sealing surfaces are soft, flexible, and
sealing properly. Hard seals may allow debris through
to the secondary filter.
• Ensure canister retaining latches are secure.
NOTE:
• Do NOT remove the secondary filter element unless it
needs replacing.
• Do NOT attempt to clean the secondary element (A).
Replace only.
