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, eliminat-
ing the possibility of dust leaks due to improper filter
installation. Intake design, internal baffling, and a
Vacuator™ valve provide dust separation and auto-
matic precleaning action. Daily or frequent servicing
of the air cleaner is not required. Use the air re-
striction gauge on the air cleaner outlet to indicate
when the air filter needs servicing -- a red flag will
appear 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.

IMPORTANT: The Donaldson air cleaner uses a dry
paper-type air filter element. NEVER apply oil to the
paper element.
Air Restriction Gauge Location
Clean and inspect the paper element after every
100 hours of service and replace the element year-
ly or after six (6) cleanings (or when dirty or dam-
aged). More frequent cleaning may be required
when operating in extremely dusty conditions as in-
dicated by the air restriction gauge. Service the air
cleaner as follows:
1. Release the top and bottom cover latches and
remove the air cleaner cover. Wash the cover
and Vacuator™ valve. Check that these com-
ponents are in good condition. The Vacuator™
valve is subject to wear and deterioration and
should be 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 resistance 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 minimize the amount
of dust dislodged as the filter is removed.
3. Clean the filter element using low pressure
compressed air [less than 100 PSI (689 kPa)].
Blow out the filter from the interior of the ele-
ment while turning the element.
NOTE: Washing the element in water or clean-
ing solution is not recommended. Replace the
element if it does not clean up with compressed
air.
