Introduction
CONTROLS & INSTRUMENTS
(continued)
CONTROL PANEL
Located on right side of seat. The following are located on the control panel.
A. Hand Throttle: Located outside top corner. This
hand throttle is used for hose/handgun spraying,
spraying and sprayer calibration. It controls engine
RPM, forward for fast, opposite direction for slow.
3200 RPM maximum sprayer output. This does NOT
control speed of travel.
B. Choke: Located at the bottom outside corner. Pull
out the choke when starting cold engine, push in
when engine starts.
C. Right and Left Boom Switches: Located to the top
of the control panel. These toggle switches are used
to raise and lower the right and left electric actuated
booms.
D. Hydraulic Pump Control: Located below boom lift
switches. Push forward to engage spray system
pump, pull back to disengage. Always engage pump
below 2000 RPM engine speed. Disengage pump
immediately after all spray material has been
discharged.
SEAT ADJUSTMENT
Adjustment lever is located under the front of the seat on the right side. It allows the seat to be adjusted for-
ward or backwards for the operator’s comfort. For further adjustment unbolt seat from seat panel, move to
other set of holes and re-bolt.
STEERING
Hydraulic steering. Before operating acquaint yourself with the steering.
Avoid sharp turns at high speeds, on slopes or unsafe terrain.
ELECTRONIC SPRAY CONTROL SYSTEM
Pressure must be set with sprayer in operation (booms on). Increase pressure by pushing the pressure ad-
justment handle upwards. Once the console reaches maximum pressure, the motorized control valve in the
sprayer then begins to open and pressure begins to decrease. Push switch in either direction until desired
pressure is reached. The system provides operation of one, two or three booms and it controls sprayer pres-
sure indicated by a wet pressure gauge on the vehicle. The pressure gauge reads the pressure in psi. The
control system is operated by the 12 volt electrical system of the vehicle. The master switch controls all boom
switches. Boom switch #1 controls left boom, boom switch #2 controls center boom, and boom switch #3 con-
trols right boom. Pressure switch increases or decreases spraying pressure through the motorized control
valve.
ELECTRICAL CONNECTIONS
Use dielectric grease on all electrical connection.
