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.

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.
