INTRODUCTION:
- Hydraulic Fluid : CASE AKCELA HY-TRAN® ULTRA™ HYDRAULIC TRANSMISSION OIL is specifically designed for high pressure applications and for Case hydraulic systems. Your Case Dealer can provide hydraulic fluid to fulfill different climate/temperature conditions. Refer to the charts at the beginning of this section.
- Transmission Component Oil: Extreme pressure oil should be used for enclosed transmission components. Choose an oil that is manufactured for your climate/temperature conditions such as CASE AKCELA NEXPLORE™ FLUID. See charts at the beginning of this section.
- Grease: The type of grease to use depends on ambient temperature such as: CASE AKCELA MOLY GREASE.
- Environment:Before servicing machine and disposing oil, fluids, and lubricants, follow all environmental regulations. Do not drain oil or fluids on to the ground or into containers that leak. Check with your local environmental recycling center or your dealer for correct disposal information.
Engine Oil: - CASE AKCELA ENGINE OIL 15W-40 is recommended for your engine. This oil insures correct lubrication of your engine in all working conditions. See charts at the beginning of this section to choose the correct oil for climate/temperatures. If CASE AKCELA ENGINE OIL 15W-40 cannot be obtained, use only oil of the API SERVICE CI-4 category.
