Cleaning can be carried out entirely on the treated area (good practice) Full use of spray liquid Prevents contamination of surface water by improper spray cleaning in the yard Extension kit for internal cleaning of high-pressure sprayers Cleaning process: Empty sprayer on field Pressure drops, air enters through nozzles Switch on the pump while the spray pump is still running First spray the solution at full concentration on an untreated area of the field (spray window) As soon as approximately half of the clean water has been used, activate the spray boom sections and the main switch (on/off) and briefly open all other functional lines that have been filled with spray solution (filter nozzle, agitator, etc.) The cleaning process is complete once the clean water has been used up For field sprayers up to 2500 litres For field crops/arable farming with hydraulic drive
