Manual Rate Control - Spray Application
After completing the filling process, you are now
ready to start spraying. While travelling from the fill
station to the field, the pump should be running at
400 - 500 rpm with the agitator running in order to
ensure that the chemical mix is adequately agitated
prior to spraying.
NOTE: The following information is provided as a
guide only. It is the responsibility of the operator to
assess the conditions in the field where the spray
application is taking place
NOTE: The bypass ball valve must be open while
spraying.
1. Enter the field, unfold boom and set the boom to
desired height above the target and have pump
running.
2. Flip all boom section switches ON.
3. Flip master switch ON.
4. Remain stationary until all boom lines have been
completely purged with product from the main
tank.
5. Flip master switch OFF.
6. Commence travel on primary swathe and flip
master switch ON to start spraying. Maintain a
constant application rate by adjusting speed and
flow rate to balance each other out as calculated
in Chapter 6 'Calibration'.
7. To avoid overlap it is recommended that
individual boom section switches are used to turn
on/off sections as needed.
8. Upon completing the spray task, flip master
switch OFF.
9. The booms and pump should be flushed after
spraying. See 'Flushing' section later in this chapter.
