Gearbox
—————
Maintain the oil level with 80w–90 gear lube up to the oil level plug on the side of the gearbox. See
Specifications and Fluids page at the back of this manual for recommended gearlube.
Hydraulic System
—————
Escaping hydraulic oil under pressure may penetrate the skin, causing personal injury.
Before disconnecting lines, relieve all pressure. Be sure all connections are tight and hoses are
not damaged.
It is recommended to change hydraulic oil every 500 hours or once per season. See Specifications and
Fluids page at the back of this manual for hydraulic oil recommendation to provide the best performance and
life. Change the return filter element every 500 hours. This element may be removed from the filter body without
removing the top cover of the tank. There is a suction strainer located inside the oil tank. Should it become
necessary to service this strainer, you must first remove the top cover from the tank. Maintain oil level within sight
gauge at all times. The hydraulic pump coupled to the gearbox at the front of the harvester is protected by a relief
valve. This relief valve is set at 2500 P.S.I. and must be maintained to insure proper operation of the harvester.
Bearing and Universal Joint Lubrication
—————
Note! Do not over grease bearings or PTO shafts.
1. Lube driveshaft U-joints twice daily.
2. Lube suction fan outer bearing every 15-20 hours.
3. Lube suction fan inner bearing every 150-200 hours.
4. Lube all other bearings every 50 hours.
5. Lube telescoping section of PTO shaft (between tractor and harvester) every 15-20 hours of operation.
