12. Press [CAL] until the red light turns off. You can also
exit calibration mode by driving the sprayer.
Calibrating the Speed Sensor
The Spray Pro comes approximately calibrated for the
speed sensor. Complete the following procedure to fine
tune the speed sensor calibration:
1. Check and fill all tires; refer to Checking Tire Pressure,
page 13.
2. Fill the fresh water tank.
3. Fill the sprayer tank half-full of water.
4. Select a straight, flat track of ground that is similar to
your turf conditions.
Note: Using a road or other paved surface could cause an
inaccurate reading when you later drive the sprayer on turf.
5. Measure 500 feet, marking both the start and end points.
6. Position the sprayer about 30 feet behind the starting
point.
7. Set the pump and the master boom switches to the Off
position. The monitor should display "HOLD."
8. Turn the selection dial to the Distance position.
9. Press and hold [RESET] until the display reads "0."
10. Drive the machine from the start point you marked to
the 500 ft end point. Ensure that you come up to speed
before reaching the start point and do not stop or brake
until after you pass the end point. When you reach the
start point, press the master boom switch to start the
distance tracking with the monitor.
11. When you reach the end point, set the master boom
switch to the Off position to stop the monitor.
12. Look at the distance displayed on the monitor.
If it reads "500 feet," you do not need to calibrate
the monitor any further.
If it does not read "500 feet," continue with the rest
of this procedure.
13. Set the parking brake.
14. With the selection dial set to the Distance position,
press and hold [CAL] until the monitor displays "CAL
HOLD" and the red light on the monitor illuminates.
The display will alternate between the speed calibration
value and the distance value.
15. When the distance value is displayed, use the [+] or [–]
buttons to change it to 500 feet.
16. When the display begins alternating again, the speed
calibration value will have changed; write this number
down and save it. This is the calibration value for your
sprayer.
17. Press [CAL] until the red light turns off. You can also
exit calibration mode by driving the sprayer.
Resetting an OFL Condition
If the monitor reads "OFL," it indicates that you have
exceeded the monitor screen dimensions. Press and hold
[RESET] to set the display to 0.
Adjusting the Boom Bypass
Valves
After you install your booms and nozzles and before using
the sprayer for the first time, adjust the boom bypass valves
so that the pressure and application rate remains the same
for all booms when you turn one or more booms off.
Select an open flat area to perform this procedure.
1. Fill the spray tank with clean water.
2. Put the extension booms down, if installed.
3. Set the parking brake and start the engine .
4. Set the dial on the Spray Pro monitor to Application
Rate.
5. Place the range selector in the Neutral position.
6. Press the accelerator to the floor and set the neutral
engine speed control switch to the On position.
7. Set the pump switch to the On position to start the
pump.
8. Set all three boom switches and the master boom switch
to the On position.
9. Use the application rate switch to adjust the pressure as
read on the pressure gauge until it is in the range for the
nozzles you installed on the booms (typically 50 psi).
10. Record the reading on the pressure gauge.
11. Turn off one of the booms using the appropriate boom
switch.
