8.5.2 Adjusting the spraying
height
WARNING
Danger of crushing and impact for persons
staying in the danger zone when lifting or
lowering for height adjustment of the spray-
ing boom!
Instruct persons to leave the danger zone
around the machine before lifting or lowering the
spray boom by means of the height adjustment.
NOTE
Adjust the spraying height (distance be-
tween nozzles and crop) as per currently
applicable guidelines.
Always adjust the spraying boom parallel to
the ground, because the specified spraying
height can only be achieved in this condition.
Carry out all adjustment work on the spray
boom conscientiously.
8.5.3 Spraying pressure, nozzle
size, application quantity, travel
speed, agitator
Should the spraying pressure drop consider-
ably all of a sudden, the spraying mixture tank
is empty.
Should the spraying pressure drop under oth-
erwise unchanged conditions, the suction or
pressure filters are blocked.
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 spraying mix-
ture. The smaller droplets are subject to higher,
undesired windward drifting!
¾
Increasing the spraying pressure also in-
creases the placing quantity.
¾
Decreasing the spraying pressure also
reduces the placing quantity.
Increasing the travel speed while leaving both
nozzle size and spraying pressure unchanged,
reduces the spraying quantity.
Reducing the travel speed while leaving both
nozzle size and spraying pressure unchanged,
increases the spraying quantity.
The travel speed is freely selectable, based on
the automatic, area related spraying quantity
control via the spraying computer.
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.
Example:
Required application quantity: 200 l/ha
Intended travel speed:
8 km/h
Nozzle type:
AI / ID
Nozzle size:
03
Permissible pressure range for
the installed spraying nozzles:
3 bar (min.) -
8 bar (max.)
Intended spraying pressure:
3.7 bar
Permissible spraying pressures: 3.7 bar ±25%
2.8 bar (min.) -
4.6 bar (max.)
