This servicing information is provided as a best practices guide. It is not intended to replace or supersede the service instructions supplied by your engine or vehicle manufacturer. 

1. Check the Restriction  
Replace the filter only when the restriction level has reached the maximum recommended by the engine or equipment manufacturer or on a regular scheduled service. 

2. Remove the Primary Filter
Push down on the service handle to tilt the filter to a 5º angle. This will loosen the seal. Then, pull up on the service handle to remove the filter from the housing.

NEVER use a pressure sprayer to clean out the air cleaner housing while it is installed on the machine

3. Visually Inspect the Safety Filter
Remove any excess dirt and wipe out the housing with a damp cloth before servicing the safety filter. Visually inspect the safety filter but do not remove it unless it is damaged or due for changeout. Verify that the safety filter is properly seated in the housing. The safety filter should be replaced every three primary filter changes. 

4. Remove Safety Filter if Indicated or if Excessively Contaminated
To remove the safety filter, use the plastic handle on the face of the safety filter. Pull the filter toward the center of the housing and remove it. Ensure that the outlet tube sealing area is clean and undamaged. If the safety filter is removed and the new filter is not to be installed immediately, be sure to cover the seal tube with a cloth so that dirt is not admitted. After removing the safety filter, wipe the air cleaner housing interior and seal surfaces with a clean, damp cloth.


The safety filter should be replaced every three primary filter changes.

5. Inspect the New Filters
Visually check for cuts, tears or indentations on the sealing surfaces and the media pack before installation. If any damage is visible, do not install. 

6. Replace the Safety Filter  
If replacing the safety filter, use the plastic handle. Slide the filter at an angle into the outlet side and push it in place until the filter seats firmly and evenly within the housing. 

7. Insert the primary filter  
Slide the filter down at approximately a 5º angle until it makes contact with the end of the housing. Rotate the filter toward the outlet section to complete the seal.

8. Replace the Service Cover
Place the service cover in position and fasten the metal latches. If the cover doesn’t seat, remove and re-check the filter position and access cover orientation. 

9. Inspect the Entire Air Cleaner System
Make sure that inlet and outlet connections are in good condition. Torque to and do not exceed 40 in-lb. Replace rubber connectors if necessary and reset the service indicator.
