Maintenance • DO NOT start the unit if the engine oil level is below the ADD mark on the dipstick. • Normal operating level is in the cross-hatch pattern between the full and add markings on the dipstick. • Add oil only if the oil level is below the add mark on the bottom of the cross-hatch pattern on the dipstick. DO NOT OVERFILL. • Check the fuel level. • If the unit is connected to a remote start or transfer switch, verify the remote switch is off and tagged.
Maintenance Basic Maintenance Schedule—Kubota Engine Item Daily Check oil level Check coolant level Check fuel level Check tire pressure Inspect wheel bearings Inspect all electrical connections Inspect radiator fins for debris; clean as required Inspect light tower winch for correct operation Inspect fan belt for tightness Inspect radiator hoses and clamp bands First 50 Hr Every 750 Hr Replace fuel filter element Replace air filter element * Replace engin
Maintenance Resetting the Maintenance Alarms (If Equipped) 2. Verify the cable and cable attachments are not damaged. Contact Generac Mobile to order a replacement cable if necessary. The Power Zone-DLA controller will display a warning message when the unit is due for maintenance or service. The maintenance or service interval is set at 750 hours of engine running time. Once the unit has been serviced, the appropriate maintenance alarm reminder needs to be reset.
Maintenance Winch Mechanical Brake The mechanical brake generates heat when loads are lowered and the wire cable is powered out. Avoid overheating the mechanical brake. Overheating the mechanical brake may result in permanent damage to, or failure of, the brake. Replace any damaged brake components before resuming use of the winch. Whine or chatter associated with a new mechanical brake is normal and typically disappears with use.
