Maintenance Instructions CLEANING

Turbine Precleaner
The turbine precleaner is mounted on a remote air
intake tube connected to the Donaldson air cleaner.
A spinning fan driven by the intake airflow separates
dust from the air, giving the initial stage of air clean-
ing. Dust particles are exhausted through a single
small vent in the side of the housing. Since no dust
is trapped, the precleaner operates without clean-
ing. The only maintenance required is to check the
operation of the internal fan every 100 hours. Verify
operation:
1. Look into the exhaust vent while shining a light
into the intake.
2. Start the engine and watch the fan begin to spin
as the throttle is advanced.
If the fan is not spinning, service or replace the pre-
cleaner as required.
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 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:
