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 bafing, and a
dust ejection valve provide dust separation and
auto matic precleaning action. Daily or frequent ser-
vicing 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
airow 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 efciently.

Inspect the paper 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 ex-
tremely dusty con ditions as indicated by the air lter
restriction gauge. Ser vice the air cleaner as fol-
lows:
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 ejec-
tion valve is subject to wear and deterioration
and should be inspected carefully and replaced
yearly or when damaged. The lips of the valve
should close and t togeth er; any cracks, defor-
mation, or wear in the valve is cause for re-
placement.
2. Remove the lter element by pulling it out of the
canister. There will be some initial resistance
as the lter seal breaks loose and slides off 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 minimize
the amount of dust dislodged as the lter is re-
moved.
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 re-
placed.
