Electric Hydraulic Pump
An electric hydraulic pump activated by a toggle
switch on hydraulic manifold provides hydraulic
power to raise or lower heavy components in the
event of a hydraulic pump failure. This pump is
capable of raising only one component at a time.
Hydraulic Manifolds
The Hydraulic manifolds are mounted to the chas-
sis behind the driver side of the cab. Electric so-
lenoid valves activated by switches in the control
panels direct hydraulic pressure to the various
components in the hydraulic system. It is also
equipped with a regulator between the low and
high pressure side of the manifold that is used
to adjust the low pressure setting. The solenoid
valves are a cartridge type design that are easily
replaced in the event of a failure.
Manual Down Pressure Valve
Down pressure on the cutter arm is set and con-
trolled by a manual bypass valve located near the
hydraulic manifold or digital controls on the cab
touch screen controller. A gauge near the valve
indicates down pressure on the arm.
Down pressure is adjusted by the operator when
the cutting mode is changed. Rotating the valve
clockwise increases pressure, rotating the valve
counter clockwise decreases pressure.
Refer to the Operation section for additional in-
formation on setting down pressure and pressure
requirements for different modes of operation.
