2. Cover the air inlet opening with a clean cloth, or
seal with tape in order to prevent dirt and debris
from entering the engine.
3. Tap the element in order to dislodge dirt
particles. Gently brush the element with a soft
bristle brush.
NOTICE
Do not use gasoline, steam, caustic or unapproved
detergents, or partscleaning solvents. Do not use high
pressure water or air to clean the air cleaner element.
Any of those liquids or methods can cause air cleaner
element damage.
4. Spray the element with the cleaning solution.
Allow the element to stand for 20 minutes.
5. Rinse the element with low water pressure. The
maximum water pressure for this procedure is
275 kPa (40 psi). Tap water is acceptable. Start
to rinse the element from the clean side (inside).
Next, clean the dirty side (outside) in order to
flush out dirt. Inspect the element for tears and/or
holes after the element is cleaned. Do not reuse
damaged elements.
NOTICE
Do not use compressed air, open flame, or hot air to
dry the air cleaner element. Excess heat shrinks cot-
ton fiber, and compressed air may blow holes in the
material. Allow the air cleaner element to air dry.
6. Shake excess water off the element, and allow
the element to air dry. Drying the element in the
sun speeds the process.
NOTICE
Do not use transmission fluid, engine oil, diesel fuel,
or other lubricant to oil the air cleaner element. The
air cleaner element can not function correctly if im-
proper oil is used. Never operate an engine with a
dry air cleaner element. The air cleaner element can
not function correctly without oil. Always saturate the
clean air cleaner element with the recommended oil.
7. The dry element should be oiled before
installation. Apply small amounts of oil across
the top of each pleat. Allow the oil to soak into
the element for 20 minutes. Oil any remaining
“white” spots.
8. Inspect the housing and the clamp for the
element. Replace the housing and the clamp,
if necessary.
9. Remove the seal from the air inlet opening.
Install the clean, oiled element. Refer to the
Operation and Maintenance Manual, “Torque
Specifications” topic (Maintenance Section).

Indicator - Inspect
SMCS Code: 7452-040
Some engines may be equipped with a different
service indicator.
Some engines are equipped with a differential
gauge for inlet air pressure. The differential gauge
for inlet air pressure displays the difference in the
pressure that is measured before the air cleaner
element and the pressure that is measured after
the air cleaner element. As the air cleaner element
becomes dirty, the pressure differential rises. If your
engine is equipped with a different type of service
indicator, follow the OEM recommendations in order
to service the air cleaner element.
A service indicator may be mounted on the air
cleaner element or in a remote location.
