Installation & Maintenance Notes
For equipment using the AF4878 air filter, general service steps include:
- Shut down the engine and allow the air intake system to cool before servicing.
- Open the air cleaner housing and remove the old primary element (AF4878 or AF25220).
- Inspect the secondary element (AF25215) — replace it every 2–3 primary element changes, or immediately if visibly contaminated, and never clean or reuse it.
- Inspect the housing for dust buildup or debris before installing new elements.
- Install the new filter(s), ensuring the element seats evenly to prevent unfiltered air bypass, and secure the housing cover.
- Follow your equipment’s OEM service schedule, typically based on hours or a restriction indicator reading.
