Hydraulic Hose Hookup
!
WARNING!
Escaping fluid under pressure can have sufficient pressure to
penetrate the skin causing serious injury. Avoid the hazard by
relieving pressure before disconnecting hydraulic lines. Use a
piece of paper or cardboard, NOT BODY PARTS, to check for
leaks. Wear protective gloves and safety glasses or goggles
when working with hydraulic systems. If an accident occurs, see
a doctor immediately. Any fluid injected into the skin must be
surgically removed within a few hours or gangrene will result.
Great Plains hydraulic hoses are color coded to help you
connect hoses to your tractor outlets.
To distinguish hoses on the same hydraulic circuit, refer to
plastic hose holders. See Figure 1-3. Hoses under the ex-
tended-cylinder symbol feed cylinder base ends. Hoses
under retracted-cylinder symbol feed cylinder rod ends.

NOTE: SAE O-ring and JIC 37˚ flare-type hose connec-
tions do not require sealant or high torque for a good seal.
Carefully check all hoses to make sure none will be dam-
aged by implement operation. Reroute hoses or use cable
ties to keep hoses in a safe place.
Bleed the Hydraulics
To function properly, the hydraulics must be free of air. If
the hydraulics have not been bled, the implement will fold
in jerky, uneven motions or some frame sections will run
higher than others. If the hydraulics were not bled during
initial implement setup or if you replace a part in the hy-
draulic system during the life of the drill, complete the fol-
lowing procedures.
