¾
Choose a slow travel speed and a low
spraying pressure to prevent losses by
windward drifting!
¾
See also chapter “Nozzle selection”.
¾
Apply additional measures for windward drift
reduction at wind speeds of 3 m/s.
¾
See chapter “Measures for windward drift
reduction”.
¾
Refrain from treatments at average wind
speeds in excess of 5 m/s (leaves and small
twigs are moving).
¾
Switch spraying on and off only when driving
to avoid overdosing.
¾
Avoid overdosing caused by overlapping
•
in case of inaccurate joining passes from
one spraying track to the next and/or
•
when cornering at the headland with
spraying boom switched on!
¾
During spraying operation keep an eye on
the actual spraying mixture consumption
in relation to the treated area. In case of
discrepancies between the actual and the
displayed placing quantity calibrate the flow
meter.
¾
Teach procedures must be carried out by
HORSCH service staff.
¾
In case of deviations between the actual and
the displayed distance calibrate the position
sensor (pulses per 100 m). This activity should
always be executed in the field.
¾
Teach procedures must be carried out by
HORSCH service staff.
¾
In case of weather related interruptions of
spraying operation it is mandatory to clean
filters, pump, fitting and spraying lines!
Folding boom control
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 spraying boom by means of the height ad-
justment.
NOTE
Adjust the spraying height (distance between
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.
Spraying pressure, nozzle size,
placing quantity, travel speed,
agitator
Should the spraying pressure drop considerably
all of a sudden, the spraying mixture container
is empty.
Should the spraying pressure drop under
otherwise 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
mixture. The smaller droplets are subject to
higher, undesired windward drift!
¾
Increasing the spraying pressure also
increases the placing quantity.
¾
Decreasing the spraying pressure also
reduces the placing quantity.
