Current Style Color Coded Hose Handles
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.
For hydraulic fan and drive motors, connect the hose
under the retracted cylinder symbol to the pressure side
of the motor. Connect the hose under the extended
cylinder symbol to the return side of the motor.
The fan motor further requires hookup of a third line,
which returns hydraulic fluid from the fan motor case.
Older Style Hoses with Color Ties
Great Plains hydraulic hoses are color coded.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 hose label. The hose under an extended-cylinder
symbol feeds a cylinder base end. The hose under a
retracted-cylinder symbol feeds a cylinder rod end.
For hydraulic fan and drive motors, connect the hose
under the retracted cylinder symbol to the pressure side
of the motor. Connect the hose under the extended
cylinder symbol to the return side of the motor.
The fan motor further requires hookup of a third line,
which returns hydraulic fluid from the fan motor case.
