Maintenance Instructions CLEANING62Turbine PrecleanerThe turbine precleaner is mounted on a remote airintake tube connected to the Donaldson air cleaner.A spinning fan driven by the intake airflow separatesdust from the air, giving the initial stage of air clean-ing. Dust particles are exhausted through a singlesmall vent in the side of the housing. Since no dustis trapped, the precleaner operates without clean-ing. The only maintenance required is to check theoperation of the internal fan every 100 hours. Verifyoperation:1. Look into the exhaust vent while shining a lightinto the intake.2. Start the engine and watch the fan begin to spinas the throttle is advanced.If the fan is not spinning, service or replace the pre-cleaner as required.Donaldson Radialseal™ Air CleanerA remote mounted Donaldson Radialseal™ aircleaner provides the air filtering function. The paperfilter element slides over an outlet tube inside the aircleaner canister with radial sealing action, eliminat-ing the possibility of dust leaks due to improper filterinstallation. Intake design, internal baffling, and aVacuator™ valve provide dust separation and auto-matic precleaning action. Daily or frequent servic-ing of the air cleaner is not required. Use the airrestriction gauge on the air cleaner outlet to indicatewhen the air filter needs servicing -- a red flag willappear when the filter is overly restricting airflow intothe engine.IMPORTANT: Use only Donaldson air filter ele-ments for replacement (Donaldson P822686 orWalker 5090-1). Aftermarket filters may not sealproperly or filter efficiently.Air Cleaner Components(shown with cover being removed)IMPORTANT: The Donaldson air cleaner uses a drypaper-type air filter element. NEVER apply oil to thepaper element.Air Restriction Gauge LocationClean and inspect the paper element after every100 hours of service and replace the element andsafety filter yearly or after six (6) cleanings (orwhen dirty or damaged). More frequent cleaningmay be required when operating in extremely dustyconditions as indicated by the air restriction gauge.Service the air cleaner as follows:CanisterCoverVacuator™ValveCover LatchRadialseal™Filter ElementAir RestrictionGaugePush Button to ResetIndicator After Service
