side-to-side to break the seal.
6. Are you replacing the safety filter?
 If yes, carefully remove the safety filter by gently
moving it side-to-side to break the seal.
 If no, continue with the next step.
7. Use a clean, dry cloth to wipe away any dirt or other
contaminants from the sealing surfaces of the outlet
tube.

Do not leave any dirt on the sealing surfaces
of the outlet tube because it can prevent a
good seal with the new filters or enter the
engine.
8. Examine the old filters for signs of damage. For example, a streak of dust on the inside surface of the filter indicates a
possible leak. Remove or repair any possible causes of leaks in the air cleaner before installing new filters.
9. Examine the new filters for signs of damage. Do not install damaged filters.
10. Are you installing a new safety filter?
 If yes, insert the safety filter into the air cleaner housing. Make sure it sits fully in the housing.

sits fully in the housing.
12. Put the cover back on the air cleaner, and hold it in place by folding down the 3 clips.

filter before it is in place, push the filter further into the housing before putting the cover
back on.
