Tractor Hydraulic Hose Hookup
High Pressure Fluid Hazard:
Only trained personnel should work on system hydraulics!
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,
seek immediate medical attention from a physician familiar
with this type of injury.
Refer to Figure 10
Current Style Color Coded Hose Handles
Great Plains hydraulic hoses have color coded handle
grips to help you hookup hoses to your tractor outlets.
Hoses that go to the same remote valve are marked with
the same color.
Note: Markers are normally on Fold circuit.
To distinguish hoses on the same hydraulic circuit, refer
to the symbol molded into the handle grip. Hoses with an
extended-cylinder symbol feed cylinder base ends.
Hoses with a retracted-cylinder symbol feed cylinder rod
ends.
Older Style Hoses with Color Ties
Refer to Figure 11
Hoses that go to the same remote valve are marked with
the same color tie.
To distinguish hoses on the same hydraulic circuit, refer
to plastic hose label. The hose under an extended-cylin-
der symbol feeds a cylinder base end. The hose under a
retracted-cylinder symbol feeds a cylinder rod end.
