dislodge loose surface dirt. Do not clean in any
liquid or use compressed air as these will damage
the filter element.

wear. Replace the element or housing if necessary.
4. Wipe the cover and base with a clean rag to remove
any dirt. Make sure that the sealing surfaces fit
correctly, and reattach the spring clips.
