Installing the Hydraulic Components—For Models Serial No. 240000001 and Above Connecting the Elevator Motor 1. Install the hose cover 122 cm (48 inches) over the hydraulic hose included with the core harvester (Figure 16). Connecting the Hydraulic Hoses Note: The machine must have the high flow hydraulic control kit (Model No. 07228 or Model No. 07316) installed. 1. Install the hose cover 147 cm (58 inches) to the hydraulic hose A—254 cm (100 inches, 8 FJ to 6 MP) as shown in Figure 15.
Connecting the Hydraulic Hoses to the Machine 3. Important: Always cover the connectors when you disconnect them to prevent damaging the hydraulic system. WARNING Hydraulic fluid escaping under pressure can penetrate skin. Fluid injected into the skin must be surgically removed within a few hours by a doctor familiar with this form of injury, or gangrene may result.

Connecting the Elevator Motor 1. Connecting the Hydraulic Hoses to the Machine Install the hose cover 122 cm (48 inches) over the hydraulic hose included with the core harvester (Figure 20). WARNING Hydraulic fluid escaping under pressure can penetrate skin. Fluid injected into the skin must be surgically removed within a few hours by a doctor familiar with this form of injury, or gangrene may result. • Keep your body and hands away from pinhole leaks or nozzles that eject high-pressure hydraulic fluid.
