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.

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.

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 .
