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 a cylinder base end.
Hoses with 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.
Machine Damage Risk:
Case Drain Hose must be attached first,
prior to inlet and return hoses being connected.
Case Drain Hose must be detached last,
to prevent damage to the fan motor.
