Maintenance Instructions CLEANING65Donaldson 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 LocationInspect the paper element after every 100 hours ofservice and replace the element and safety filteryearly (or when dirty or damaged). More frequentreplacement may be required when operating in ex-tremely dusty conditions as indicated by the air re-striction gauge. Service the air cleaner as follows:1. Release the top and bottom cover latches andremove the air cleaner cover. Wash the coverand Vacuator™ valve. Check that these com-ponents are in good condition. The Vacuator™valve is subject to wear and deterioration andshould be replaced yearly or when damaged.The lips of the valve should close and fit togeth-er; any cracks, deformation, or wear in the valveis cause for replacement.2. Remove the filter element by pulling it out of thecanister. There will be some initial resistance asthe filter seal breaks loose and slides off of theoutlet tube. Gently move the end of the filter upand down and side to side or twist to loosen theseal. Use gentle action to minimize the amountof dust dislodged as the filter is removed.3. Replace the filter element.NOTE: Washing the element in water or clean-ing solution is not recommended. Do not try toclean the element with compressed air.CanisterCoverVacuator™ValveCover LatchRadialseal™Filter ElementAir RestrictionGaugePush Button to ResetIndicator After Service
