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 courtyard 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.
