Control Valve
CAUTION
The hydraulic oil must be kept clean to prevent
damage to the control valve.
The control valve is part of the lift pump and mo-
tor assembly and is replaceable but not adjustable.
When the operator selects a hydraulic function by
pressing a button on the control handle, a signal is
sent to the traction/lift controller, is processed, and
is sent to the pump assembly. Lifting speed is con-
trolled by varying the pump motor speed. Lower-
ing speed is controlled by a proportional electro-hy-
draulic valve on the pump assembly.
The control valve is designed with close tolerances
and must be kept clean to work properly.
