Cleaning the Foam and Paper Elements

1. Wash the foam element in liquid soap and warm
water and rinse it thoroughly.
2. Dry the element by squeezing it in a clean cloth.
3. Saturate the element in engine oil.
4. Squeeze the element in a clean, absorbent cloth to
remove excess oil.
Important: Replace the foam element if it is torn
or worn.
Paper Element
1. Lightly tap the paper element on a flat surface to
remove dust and dirt.
2. Inspect the element for tears, an oily film, and
damage to the rubber seal.
Important: Never clean the paper element with
pressurized air or liquids, such as solvents, gasoline,
or kerosene. Replace the paper element if it is
damaged or cannot be cleaned thoroughly.
Installing the Foam and Paper Elements

operate the engine with the complete foam and
paper air cleaner assembly installed.

Note: Ensure that the rubber seal is flat against the
air cleaner base.
2. Position the paper element on the foam element in
the air cleaner base.
3. Install the air cleaner cover and knobs (Figure 20).
4. Tighten the knobs snugly.
