Cleaning the field sprayer on the field

Perform the cleaning of the spray liquid circuit, the spray lines and the nozzles while driving on the field, since cleaning water is applied intermittently. You can clean the machine in the farmyard if you have a collecting facility, e.g. a Biobed.

A distinction is made between quick cleaning and intensive cleaning:

  • Quick cleaning must be performed daily.

  • Intensive cleaning must be performed before critical agent changes or before the machine is out of operation for a longer period of time.

REQUIREMENTS

  • The flushing water tank must be filled.

  • The spray liquid tank must be empty.

  1. Run the spray liquid pump.
  2. On the control terminal, select the Cleaning menu.
  3. In the Cleaning menu, select Intensive cleaning or Quick cleaning.
NOTE
The intensive cleaning procedure takes approx. 15 minutes.
During intensive cleaning, cleaning water is sprayed onto the field automatically three times.
