Adjusting The Boom Bypass Valves - Toro 41229 Operator's Manual

12. When the calibration volume is displayed, use the [+]
or [–] buttons to change it to the amount of water you
put in the tank.
13. 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 vehicle.
14. Press [CAL] until the red light turns off. You can also
exit calibration mode by driving the vehicle.
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 to their recommended pressure.
See your Workman Operator's Manual for more
information.
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 vehicle on
turf.
5. Measure 500 feet, marking both the start and end
points.
6. Position the vehicle about 30 feet behind the starting
point.
7. Set the master boom switch 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 sensor
calibration value and the distance value.
15. When the distance is displayed, use the [+] or [–]
buttons to change it to 500 feet.
16. When the display begins alternating again, the speed
sensor 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 vehicle.
Note: Using a smaller distance than 500 feet will decrease
accuracy.
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. Place the range selector in the Neutral position.
5. Set the hand throttle.
6. Engage the PTO lever to start the pump.
7. Set all three boom switches and the master boom
switch to the On position.
8. 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
40-50 psi).
9. Record the reading on the pressure gauge.
10. Turn off one of the booms using the appropriate boom
switch.
