Page 123: Preparing The Wash
12.2 Preparing the wash DANGER Strictly wear protective gloves and appropriate protective clothes! When preparing wash there is the highest risk of coming into contact with crop protection product. WARNING Danger caused by accidental contact with crop protection products and / or wash! Generally flush the crop protection product through the illuviation container into the wash container.
Page 124: Calculating Filling And Refilling Quantities
Execution 1. Determine the required water and preparation quantity by using the instructions for use of the crop protection product. 2. Calculate the filling or refilling quantity for the area to be treated. 3. Fill half of the wash container with water. 4.
Page 125: Filling Tables For Remnant Areas
12.2.2 Filling tables for remnant areas Use the "Filling table for residual areas" to calculate the required refilling quantity for the last wash container filling. Subtract the residual quantity in the spraying line from the calcu- lated refilling quantity! See also chapter "Spraying line", chapter 11.9. The specified refilling quantities apply for an application quantity of 100 l/ha.
Page 126: Filling With Water
12.3 Filling with water When filling, pay attention to the permissible payload of your crop protection sprayer! When filling your crop protection sprayer you must strictly consider the different specific weights [kg/l] of the individual fluids.

Page 134: Spraying Wash
In case of spraying operation you should continuously check the wash consumption with respect to the treated area. Calibrate the flow meter in case of deviations between the actual and the displayed application quantity. (See operating instructions "Job Computer II" Co. Müller-Elektronik). Strictly clean filters, pump, valve and spray lines in case of weather dependent interruptions of the spraying process.
Page 135: Spraying
Example Required application quantity: 200 l/ha Intended travel speed: 8 km/h Nozzle type: AI / ID Nozzle size: Permissible pressure range for the min. pressure 3 bar installed spraying nozzles max. pressure 8 bar Intended spraying pressure: 3,7 bar Permissible spraying pressures: 3.7 bar ±25% min.
Page 136: Windward Drift Reduction Measures
12.6.4 Windward drift reduction measures • Schedule your work for early morning or evening (generally less wind). • Reduce the spraying pressure • Choose bigger nozzles and high water application quantities. • Strictly maintain the exact boom working height, because the risk of windward drift will increase con- siderably with increasing nozzle distance.
Page 137: Residual Quantities
12.7 Residual quantities A differentiation is made between two types of residual quantities: • Residual quantity remaining in the wash container after the end of spraying operation. • Technical residual quantity which still remains in wash container, suction fitting and spraying line, with considerable drop in pressure.
Page 138 Diluting the residual quantity 1. Switch off the nozzles 2. Switch on the pump 3. Switch on the agitator 4. In the terminal switch over to fresh water for 15 seconds, fresh water will now circu late through the nozzle pipe and dilute the residual quantity in the tank with fresh water 5.

Spraying table Spraying tables for flat jet, anti-drift, injector and airmix nozzles, spraying height 50 cm NOTE! • All application quantities [l/ha] listed in the spraying tables apply for water. Multiply the specified application quantities with 0.88 to concert to AHL and with 0.85 to convert to NP-solution.
Page 205 Choose the nozzle type x 0.88 Nozzle spacing 50 cm x 1.14 Example: 200 l/ha Required application quantity: Intended travel speed: 8 km/h Required atomizing characteristic for the crop protection measure to be carried out: coarse drops (no windward drift) required nozzle type: required nozzle size: Required spraying pressure:...
Page 206 Determination of nozzle type, nozzle size, spraying pressure and individual nozzle output 1. Determine the operating point for the required appli- cation quantity (200 l/ha) and the intended travel speed (8 km/h). 2. At the operating point draw a vertical line down- wards.
Page 207 Universal table for crop protection sprayers with 50 cm nozzle spacing The values apply for water of 20 °C, pressure measured directly at the nozzle. Check the values with a measuring vessel before the start of application. ----- Example: 200 l/ha at 7.2 km/h require 1.20 l/min per nozzle, i.e. 6.7 bar with size -02, 4.3 bar with size -025, 3.0 bar with size -03 etc.
