1. Close the quick filling valve.
2. Switch on the pump via the terminal.
3. Set the suction side to solution tank (a).
4. Open the boom line (b).
5. Switch on agitator via the terminal and adjust
the intensity (c)
The required agitating power depends on the prepa-
rations used and must be checked by the user.
This setting also serves the purpose of stirring
the chemical when travelling to the field.
Travelling to the field with the agitator
switched on:
1. Close the quick filling valve.
2. Switch on the pump drive.
3. Switch on agitator via the terminal and adjust
the intensity (c)
Before starting spraying operation you
should reset the stirring intensity you had set
for travelling, if it deviates from the stirring
intensity required for spraying!
8.5.4 Measures for windward drift
reduction
¾
Schedule your work for early morning or even-
ing (generally less wind).
¾
Reduce the spraying pressure.
¾
Choose bigger nozzles and high water ap-
plication quantities.
¾
Strictly maintain the exact boom working
height, because the risk of windward drift will
increase considerably with increasing nozzle
distance.
¾
Reduce the travel speed (below 8 km/h).
¾
Use of so-called antidrift (AD) nozzles or
injectors (ID) nozzles (nozzles with a high
proportion of coarse drops).
¾
Follow the distance instructions for the cor-
responding crop protection agent.
8.5.5 Spraying with 25 cm nozzle
spacing and reduced target area
distance
¾
The risk of windward drifting can be consid-
erably reduced by reducing the target area
distance to less than 50 cm.
¾
This reduction of the target area distance is
only possible with continuous 25 cm nozzle
spacing. Otherwise there is a risk of strip for-
mation caused by non-existing overlapping of
the spraying cones.
¾
A distance reduction is only possible if all
nozzles used at a time are of the same type
and the same size.
¾
The minimum target area distance corre-
sponds with half the minimum target area
distance for a corresponding 50 cm nozzle
spacing → see data of nozzle manufacturer.
