Operating the Control Units While Spraying (DF4)
The control units in the tractor control the following functions in the field:
1. Power ON/OFF status LED. The light must be ON.
2. Automatic spray pressure regulation.
The regulation valve controls the main spray pressure. This is the
default selection when the controller is powered ON, and it should
remain here during normal spraying.
3. Manual spray pressure regulation.
During normal spraying, these controls should not be used, as the
regulation valve does this automatically.
4. Foam marker blob interval. Regulates the blob interval for the
optional foam marker.
5. Foam marker (Left/Right). Turns the optional foam marker ON for each side.
6. Optional function, A or B.
If extra equipment is added, it can be controlled from here.
A. Power ON/OFF/status LED. The light must be ON.
B. Section valves for spray boom. Turns separate sections ON or OFF.
• Lever up is OFF.
• Lever down is ON.
C. Main valve ON/OFF.

NOTE! Check the current volume application rate on the display,
or see the instruction book for the spray controller for more
information.
Before Returning to Refill the Sprayer
If the sprayer is to be refilled at a filling location without a dedicated filling site (with hard surface and drain to a closed
reservoir), the sprayer should be rinsed in the field before returning to refill.
Dilute the residues of the spraying circuit and spray it on the crop. Then rinse the outside of the sprayer with the External
Cleaning Device (optional) before returning to refill.
