CLUTCH
An ON/OFF switch that activates the pneumatic
solenoids that engage and disengage the auxiliary
engine PTO clutch. A green LED light in the switch
indicates that the clutch is engaged.
FLOAT SWITCH
Activates and deactivates the float mode feature
that enables the Hog Head to float freely over un -
even road surfaces. A green LED light in the switch
indicates that float mode is engaged.
CHARGE PUMP
Activates the solenoid valve that supplies pres-
surized hydraulic fluid to power the charge water
pump. A green LED light in the switch indicates the
charge pump is activated.
HEAD ROTATION
An ON/OFF switch that activates the solenoid valve
that supplies pressurized hydraulic fluid to power
the hydraulic motor that rotates the spray bar. A
green LED light in the switch indicates that the mo-
tor is engaged. Head rotation speed is controlled
by the HEAD ROTATION speed dial.
PTO
• Disengages the truck drive system and ener-
gizes the circuits for all other rocker switches on
the control panel, joystick, and digital gauges.
A green LED light in the switch indicates that
the PTO switch is on and the panel circuits are
energized.
NOTICE:
THE PTO SWITCH MUST BE ON AND THE AUXILIARY ENGINE
RUNNING TO ACTIVATE THE HYDRAULIC SYSTEM. THE
CONTROL PANEL PTO SWITCH DISENGAGES THE TRUCK
DRIVE TRAIN AND ENERGIZES THE CIRCUITS FOR ALL
OTHER PANEL SWITCHES THAT ACTIVATE THE HYDROSTATIC
DRIVE AND WATER BLASTING SYSTEM COMPONENTS. THE
PTO SWITCH ALSO ENERGIZES THE JOYSTICK AND DIGITAL
GAUGES IN THE CONTROL PANEL.
MODE
The PTO and Clutch switches are used to select
the truck operation mode, either Drive mode or
Work mode. Colored LED lights in the control panel
indicate the status of the operation mode selected.
• Green lights illuminated indicate the truck
has been successfully shifted into DRIVE
mode. All water blasting functions are can-
celled and the truck is ready for highway
operation.
• Red lights illuminated indicates the truck
has been successfully shifted into WORK
mode. The truck highway drive train is dis-
abled, the hydrostatic drive is enabled and
all water blasting functions are available
for activation.
AUX
Reserved for additional water blasting accessories.
ENGINE START
A key activated switch that starts and stops the
auxiliary engine. Once started, the engine is
controlled and monitored by the controller above
switch. Refer to the Skid Mounted Auxiliary Engine
section for additional information on the operation
of the auxiliary engine.
Joystick Control Lever
The joystick controls the motion of the Hog Arm.
Move it forward to lower the arm, pull it back to
raise it. Move it to the right and the arm moves
right, move it left and the arm moves left. When
the joystick is released, the handle automatically
returns to the center and the Hog Arm stops in
that position.
Speed Dials And Digital Gauges
The speed dials are used to select the desired
RPM for the spray bar and the speed of the truck
hydrostatic drive.
HEAD ROTATION
The Head Rotation speed dial controls the speed of
the spray bar from 0 to maximum speed. Rotating the
dial clockwise increases speed. Rotating it counter-
clockwise reduces speed. Setting the Head Rotation
dial to 0 will stop the rotation of the spray bar.
