agitation valve towards "Agitation" (If BK operating unit: turn
agitation on at lever on BK operating unit). Other valves are closed.

Before Returning to Refill the Sprayer

If the sprayer is to be refilled at the farm, or at a fixed filling place without a filling space with hard surface and drain to a
closed reservoir, the sprayer should be rinsed before returning to refill.
Dilute the residues of the spraying circuit, and spray it on the crop. Now rinse the sprayer on the outside with the External
Cleaning Device (optional equipment), before returning to the farm.
