Tank and Boom Flush
The Tank Rinse and Flush features use the fresh water in
the 100 gallon flush tank to rinse out the main sprayer
tank and boom in the field.
Before operation, make sure the Flush tank is filled with
fresh, clean water.
1. Completely empty the chemical in the main sprayer
tank by turning the agitation off the last pass and
spraying the main tank contents out in the field. To
avoid overdosing, use a higher ground speed or
lower application rate.
2. Make sure all boom valves and pump are turned off.
Refer to Figure 46
3.
Set the panel valves to:
agitation valve
to “FLUSH”,
tank valve “FLUSH TANK”, and
operation valve “SPRAY”.
4. Operate the pump with the sprayer stationary, and
rinse the tank until
1 ⁄
3
of the flush tank volume (33
gallons or 126 liters) is consumed and then stop the
pump.
5. With the sprayer pump off, turn the agitation valve
from “FLUSH” to “OFF”.
Refer to Figure 47
6.
Rotate the tank valve from “FLUSH TANK” to
“MAIN TANK”.
7. Operate the pump and spray out, in the field just fin-
ished, the full 33 gallon (126 liter) volume of liquid
(deposited into the main sprayer tank from the Flush
Tank).
8. Repeat step 2 through step 7 twice more until the
flush tank is empty and the main sprayer tank and
boom has been rinsed completely three times.
9. Reset the agitation pressure before filling the main
sprayer tank again.
