Maintenance
Washing Method
IMPORTANT: Do not remove plastic fin
assembly because washing removes dust from
beneath fins.
A. Prepare a solution of filter cleaner and water
and soak filter element about 15 minutes.
Refer to directions on filter cleaner carton
for complete information.
B. After soaking filter for 15 minutes, rinse it
with clear water. Maximum water pressure
must not exceed 40 psi to prevent damage
to the filter element.
C. Dry filter element using warm, flowing
air(160 F ) max), or allow element to
air–dry. Do not use compressed air or a
light bulb to dry the filter element because
damage could result.
Compressed Air Method
IMPORTANT: Do not remove plastic fin
assembly because back–blowing with
compressed air removes dust from beneath
fins.
D. Blow compressed air from inside to the
outside of dry filter element. Do not exceed
100 psi to prevent damage to the element.
E. Keep air hose nozzle at least one inch from
pleated paper, and move nozzle up and
down while rotating the filter element.
Inspect element when dust and dirt are
removed; refer to Inspecting Filter Element.
4. Wipe inside of air cleaner body with a damp
cloth to remove excess dust. Slide filter into air
cleaner body and secure it in place with wing nut and
gasket.
5. Reinstall dust cup and baffle. Move thumb screw
behind air cleaner body and tighten it securely.
