Donaldson Radialseal™ Air Cleaner
A remote mounted Donaldson Radialseal™ air
cleaner provides the air filtering function. The
paper filter element slides over an outlet tube
inside the air cleaner canister with radial sealing
action, reducing the possibility of dust leaks due to
improper filter installation. Intake design, internal
baffling, and a dust ejection valve provide dust
separation and auto matic precleaning action. Dai-
ly or frequent servicing of the air cleaner is not
required. Use the air filter re striction gauge on the
air cleaner outlet to indicate when the air filter
needs servicing–a yellow indicator will show when
the filter is overly restricting airflow into the engine.
IMPORTANT: Use only Donaldson air filter ele-
ments for replacement (Donaldson P822686 or
Walker 5090-1). Aftermarket filters may not seal
properly or filter efficiently.

Inspect the primary filter element after every 100
hours of service and replace the element and
safety filter yearly (or when dirty or damaged).
More frequent replacement may be required when
operating in extremely dusty con ditions as indicat-
ed by the air filter restriction gauge. Ser vice the air
cleaner as follows:
1. Release the top and bottom cover latches and
remove the air cleaner cover. Wash the cover
and dust ejection valve. Check that these
com ponents are in good condition. The dust
ejection valve is subject to wear and deteriora-
tion and should be inspected carefully and
replaced yearly or when damaged. The lips of
the valve should close and fit togeth er; any
cracks, deformation, or wear in the valve is
cause for replacement.
2. Remove the filter element by pulling it out of
the canister. There will be some initial resis-
tance as the filter seal breaks loose and slides
off of the outlet tube. Gently move the end of
the filter up and down and side to side or twist
to loosen the seal. Use gentle action to mini-
mize the amount of dust dislodged as the filter
is removed.
3. Discard the filter element if excessive air flow
restriction has been indicated by the air filter
restriction gauge and proceed to Step 6.
Clean the filter element by gently tapping on
a flat, hard surface. If excessive restriction
still exists after cleaning the element, it should
be replaced.
