booms until all the water is out of the tank, then stop
them using the master spray lever.
8. Compare the volume displayed on the monitor to the
volume of water you put into the tank.
• If the volumes are the same, you do not need to
calibrate the monitor any further.
• If the values are different, continue with the rest of
this procedure.
9. Turn the selection dial to the Flowmeter Calibration
position.
10. Press and hold Calibrate button until the red light on the
monitor illuminates.
The display will alternate between the flowmeter
calibration value (indicated by the word “CAL” on the
monitor) and the calibration volume.
11. When the calibration volume is displayed, use the
Increase or Decrease calibration buttons to change it to
the amount of water you put in the tank.
12. When the display begins alternating again, the
flowmeter calibration value will have changed; write
this number down and save it. This is the calibration
value for your sprayer.
13. Press the Calibrate button 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 14.
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 switch to the Off position.
8. Align the front of the front tire with the marked starting
point.
9. Turn the selection dial to the Calibration Distance
position.
10. Press and hold the Reset calibration button until the
display reads “0.”
11. Drive the machine from the start point you marked to
the 500 ft end point, carefully stopping so that the front
of the front tire is aligned with the end mark.
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. Turn the selection dial to the Speed Cal position.
15. Press and hold the Calibrate button until the red light on
the monitor illuminates.
The display will alternate between the speed calibration
value (indicated by the word “CAL” on the monitor)
and the calibration distance.
16. When the calibration distance is displayed, use the
Increase or Decrease calibration buttons to change it to
500 feet.
17. 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.
18. Press the Calibrate button 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
the Reset calibration button to set the display to 0.
Adjusting the Boom Bypass
Valves
After you install your booms and nozzles, if necessary, 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 .
