Next, immerse element in a solution of nonsudsing
household detergent and warm water [not to exceed 60 C
(140 F)] for approximately 15 minutes. Agitate element
occasionally to aid cleaning action.
Remove element and rinse thoroughly by running clean
water through element from clean air side to dirty side until
water passing through element is clear. Use a hose without a
nozzle and do not permit water pressure to exceed 276
kilopascals (40 psi).
Allow element to dry completely.
CAUTION: Never use compressed air or light
bulbs to hasten drying. High pressure air can
tear holes in paper pleats and light bulbs can
cause burning.
Inspect element after cleaning by inserting a light bulb
inside element and inspecting outside surface of element for
punctures or splits.
If so equipped, inspect air cleaner and element gaskets
and replace if necessary on reassembly.
It is not recommended to attempt cleaning box dry type
elements. When box dry type elements have reached
maximum allowable restriction as outlined in the applicable
operator's manual, they should be replaced.
Oil Bath Air Cleaners
Remove cover or sump. Wash mesh element and sump
in cleaning solvent or kerosene. Some oil bath air cleaners
have two mesh elements: one removable and one integral in the
body assembly.
Cleaning solvent must be flushed through element with
sufficient force and volume to dislodge foreign material. Use a
long bristle, brush to assist in dislodging any dirt or dust. Air
cleaners having integral elements can be submerged and
agitated briskly in cleaning solvent to force the cleaning fluid
through the element.
NOTE: Steam cleaners may be used to perform
the cleaning operation if the air cleaner is
unusually dirty; however, be careful not to
damage the air cleaner.
Refill sump to oil level mark and oil mesh element freely
with engine oil of same viscosity used in crankcase. Allow
excess oil to drip from element before installation.
Combination Oil Bath and Dry Type Air Cleaners
Refer to the oil bath air cleaner and dry type air cleaner
service instruction contained in this manual section to service
the corresponding sections of combination oil bath and dry type
air cleaners.
