Revision A
Cleaning Primary Air Filter
The engine air cleaner
’
s primary filter should be replaced after three cleanings or at the specified interval. The secondary
element should be replaced every third time the primary element is changed. Refer to 5.2 Windrower Break-In Inspections
and Maintenance Schedule, page 235 for the required interval.
1. Hold a bright light inside the element and check carefully for holes. Vibration will quickly wear a hole in the filter.
2. Check the filter gasket for cracks, tears, or other signs of damage.
3. Check the element for oil or soot contamination.
4. Check the secondary element for cleanliness. If there is visible dirt on the secondary element, replace both the primary
and secondary elements. Do
NOT clean the secondary element.
IMPORTANT:
•
The secondary filter element should NEVER be cleaned, only replaced.
•
Primary 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 steps should be followed. If
any of the conditions described in these steps are found, the filter element MUST be replaced.
5. If the secondary element passes inspection, use compressed air not exceeding 270 kPa (40 psi) and a dry element
cleaner gun to clean the primary element. Hold the nozzle next to the inner surface only and move it up and down on
the pleats.
NOTE:
After three cleanings (or at the specified interval), replace the primary element.
6. Repeat the inspection before installation. For instructions, refer to Installing Engine Primary Air Filter, page 292 .
Replacing Secondary Air Filter
The secondary element should be replaced every third time the primary element is changed.
IMPORTANT:
•
The secondary filter element should NEVER be cleaned, only replaced. Do NOT remove the secondary filter element
unless it needs replacing.
•
Replace the secondary element annually or after every third primary filter change, even if it appears clean.
•
If replacing the secondary element, a further inspection may be necessary.
•
Examine the filter canister for cracks and replace it as necessary.
•
Ensure the canister retaining latches are secure. Ensure the filter sealing surfaces are soft, flexible, and sealing, not hard
and allowing debris through to the secondary filter.
