SECTION 3 - LUBRICATION AND MAINTENANCE
3-12
Rinse the element with clean, running water.
Rinse from the inside of the element through to
the outside until the water is free of dirt. If a hose
is used, do not exceed 2 bar (30 PSI). A gentle
trickle of water is sufficient and will ensure that
the element is not ruptured.
Shake out excess water from the element and
allow to air dry. DO NOT use compressed air, a
light bulb or heat to dry the element.
NOTE: It usually takes one to three days for a filter
element to dry.
IMPORTANT: Do not attempt to dry the element with
heat or compressed air and do not install until
thoroughly dry as it may rupture. It is recommended
that a new or previously cleaned element be installed
at this service and the washed element put aside for
installation at the next service. The spare element
should be stored in a dry place and wrapped to
prevent dust contamination or damage.
NOTE: An outer filter element may be washed up to
six times.

5. Examine the element for damage by placing a
light inside the element. Discard the element if
pin pricks of light can be seen or if there are areas
where the paper appears thin.
6. Check the element material for bunching; the
metal casing for distortion; and the rubber gasket
for damage. Discard the filter element if it is
damaged.
7. Clean the inside of the air cleaner housing using
a damp, lint-free cloth on a probe. Do not damage
the inner filter element.
8. Install a cleaned or a new outer element. Tighten
the wing nut.
NOTE: Replace the wing nut seal if it is damaged.

9. Install the air cleaner cover, 2, and wing nut, 1.
