Donaldson Radialseal™ Air Cleaner
A remote mounted Donaldson Radialseal™ air
cleaner provides the air ltering function. The
paper lter element slides over an outlet tube
inside the air cleaner canister with radial sealing
action, reducing the possibility of dust leaks due to
improper lter installation. Intake design, internal
ba󰀪ing, 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 lter re striction gauge on the
air cleaner outlet to indicate when the air lter
needs servicing–a yellow indicator will show when
the lter is overly restricting airow into the engine.
IMPORTANT: Use only Donaldson air lter ele-
ments for replacement (Donaldson P822686 or
Walker 5090-1). Aftermarket lters may not seal
properly or lter e󰀩ciently.

Inspect the primary lter element after every 100
hours of service and replace the element and
safety lter 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 lter 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 t togeth er; any
cracks, deformation, or wear in the valve is
cause for replacement.
2. Remove the lter element by pulling it out of
the canister. There will be some initial resis-
tance as the lter seal breaks loose and slides
o󰀨 of the outlet tube. Gently move the end of
the lter 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 lter
is removed.
3. Discard the lter element if excessive air ow
restriction has been indicated by the air lter
restriction gauge and proceed to Step 6.
Clean the lter element by gently tapping on
a at, hard surface. If excessive restriction
still exists after cleaning the element, it should
be replaced.
