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 (Primary)

A remote mounted Donaldson Radialseal™ air cleaner provides the primary air filtering function (ahead of the standard Kohler engine air cleaner). The paper filter element slides over an outlet tube in- side the air cleaner canister with radial sealing ac- tion, eliminating the possibility of dust leaks due to improper filter installation. Intake design, internal baffling, and a Vacuator™ valve provide dust sepa- ration and automatic precleaning action. Daily or frequent servicing of the air cleaner is not required. Use the air restriction 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.

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:
