Preparation and Setup
Hydraulic Hose Hookup
Great Plains hydraulic hoses are color coded to help you
hookup hoses to your tractor outlets. Hoses that go to the same
remote valve are marked with the same color.
Hose Handles
To distinguish hoses on the same hydraulic circuit, refer to,
Hydraulic Hose Hookup above. The hose under an extended
symbol feeds a cylinder base end. The hose under a retracted-
cylinder symbol feeds a cylinder rod end.
Clean all hydraulic couplings and hook hoses to tractor.

High Pressure Fluid Hazard:
Relieve pressure before disconnecting hydraulic lines. Use
paper or cardboard, NOT BODY PARTS, to check for leaks.
Wear protective gloves and safety glasses or goggles when
working with hydraulic systems. Escaping fluid under pressure
can have sufficient pressure to penetrate the skin causing
serious injury. If an accident occurs, seek immediate medical
assistance from a physician familiar with this type of injury.
Only trained personnel should work on system hydraulics.
