Next remove the safety filter (replace at every third primary filter change) or support liner by pulling it straight out. This allows necessary access to properly clean the primary filter’s seal surface.
Inspect the seal surface and housing for any damage. Replace the complete air cleaner if damage is present.
It is not necessary to replace the support liner unless it is damaged. If you are reusing the safety filter keep it clean while servicing the housing to avoid contamination.
Note: If a safety filter or liner is not present, check to see if it has attached itself to the inside of the primary filter during removal. To properly service this small diameter air cleaner, you will need to remove the safety filter or liner upon each filter service.
