Page: 134 / 218

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.
In case of deviations between the actual and the displayed travel distance calibrate the distance sensor
(pulses per 100 m), see operating instructions Co. Müller-Elektronik Job Computer II Crop Protection
Sprayer.
Spraying pressure and nozzle size have an influence on the drop size and the sprayed out fluid volume.
The higher the spraying pressure, the smaller the drop diameter of the sprayed wash.
The smaller droplets are subject to higher, undesired windward drifting!
Increasing the spraying pressure also increases the application quantity - reducing the spraying pres-
sure also reduces the application quantity.
If the travel speed is increased with the same nozzle size and constant spraying pressure, the applica-
tion quantity will be reduced - by reducing the travel speed and keeping both the nozzle size and the
spraying pressure unchanged, the application quantity will increase.
The travel speed is freely selectable via the sprayer computer, based on the automatic, area related
application quantity control.
The agitator normally remains switched on from filling to the end of spraying. The information provided
by the preparation manufacturer are decisive in this respect.
The spraying container is empty when the spraying pressure drops all of a sudden.
If the spraying pressure drops under otherwise unchanged conditions, the suction and pressure filters
are clogged.
12.6.2 Spraying wash
Before starting spraying check the following machine data on the control terminal
o the values for the permissible spraying pressure range for the spraying nozzles installed in the spray-
ing boom.
o the value for "Pulses per 100 m".
Apply appropriate measures if an error message appears in the display during spraying. See also chap-
ter Faults 12.9.
Check the indicated spraying pressure during spraying.
Make sure that the indicated spraying pressure does under no circumstances deviate for more than
±25% from the intended spraying pressure as per spraying table, e.g. when changing the application
quantity with the plus/minus keys. Higher deviations from the intended spraying pressure do not enable
an optimal treatment success for your crop protection measure and will also harm the environment.
Reduce or increase the travel speed, until you have returned to the permissible range of the intended
spraying pressure.
Never spray the wash container completely empty (this does not apply for the end of spraying operations).
Refill the wash container at the latest when a filling level of approx. 50 litres is reached.
