Installing the Hydraulic Hose
The Hydraulic Hose moves Hydraulic Fluid from the Power Unit to the Hydraulic Cylinder.
To install the Hydraulic Hose, you will need the Hydraulic Hose and two Hydraulic Fittings.
Drawing not to scale. Some components exaggerated for clarity.
To install the Hydraulic Hose:
1. Find the Hydraulic Hose and the two Hydraulic Fittings.
2. Route the Hydraulic Hose through the Flex Tube; keep the Curved end at the Power Unit.
3. Remove the Shipping Plug from the Hydraulic Out Port on the Power Unit, install the ORB
connector of the JIC-to-ORB Hydraulic Fitting to the port, while the JIC connector attaches to the
Hydraulic Hose.
4. Remove the Shipping Plug from the Hydraulic Cylinder Port and install the NPT connector of the
JIC-to-NPT Hydraulic Fitting to the port, then connect the JIC connector to the Straight end of the
Hydraulic Hose.
5. Securely tighten both connections on the Power Unit and Hydraulic Cylinder.
