OPERATING AND CALIBRATION INSTRUCTIONS
CONTROL OPERATION
Deluxe RoadMaster™ Control
Follow the steps below to get started using your
deluxe control. Complete details and instructions
follow in this section.
1. Before spraying, consider what speed range
you wish to operate in and select and install the
appropriate nozzles using the application rate
charts in this manual. Note that the unit will not
function as intended outside these ranges.
2. Turn the power switch ON. The unit will display the
software version and the total hours of operation
for 1.5 seconds each. Be sure the control is set
to HOLD or the boom switches are set to OFF
before starting the Liqui Maxx™ sprayer's motor to
prevent unintentional spraying.

WARNING
Always make sure personnel are clear of
areas of danger when using equipment.
Maintain 60' distance from all bystanders
when operating the spray system.
WARNING
Vehicle handling and characteristics will
change with the unit installed. Avoid any
sudden steering maneuvers, starts, or stops
that could create sloshing and instability.
WARNING
Before operating the sprayer, verify that all
safety guards are in place.
WARNING
Unit must be strapped down and locked into
position before operating or transporting.
CAUTION
Starting the motor with no antifreeze
will damage the seal in the pump. Check
antifreeze levels before starting.
The RUN/HOLD button is the master switch
to turn all sections ON and OFF. For example,
instead of using the individual section switches,
simply use the RUN/HOLD switch.
3.
Set the valves to the spray configuration. Start the
Liqui Maxx sprayer's motor by turning the motor
ON, setting the appropriate choke, and pulling the
recoil start handle.
Spray configuration:
• Brine Fill Valve: Closed
• Shut-off Valve: Open
4. Select the spray mode by pressing the
AUTO/MAN button on the bottom left of the
control until the desired mode is displayed on the
top right of the control display. Select Automatic
Mode if you wish to have the control automatically
hold a target application rate and your unit has
a compatible speed sensor installed. If you are
doing driveways or other applications where it
is difficult to stay within a target speed range,
it may be desirable to use Manual Mode. If
speeds of 4–6 mph are desired, Manual Mode is
recommended.
Automatic Mode
1. During normal operation, set the rotary switch to
RATE to see the actual application rate per acre.
The unit will automatically adjust to the target
application rate which can be seen and adjusted
using the Up (+) and Down (−) arrow buttons on
the control. Use the RUN/HOLD button and the
boom switches to control the boom as desired.
The factory defaults below can be adjusted as
desired. See "Entering Calibration Values" in this
section.
Factory Defaults:
• Target Application Rate: 30
• Rate Increment: ± 5
• Units: Gallons/Acre
The Automatic Mode has a BLAST function
intended for spot application that requires a higher
application rate like bridges or intersections.
This can be changed to any value and it is not
associated with the standard application rate. See
"Entering Calibration Values" in this section.
