Using the machine
•
The pump delivery capacity is dependent on the pump drive
speed. Select the pump speed (between 400 and 550 rpm.) so
that there is always an adequate flow rate to the sprayer boom
and for the agitator. When making this choice, always take ac-
count of the fact that more spray liquid needs to be conveyed at
higher operational speeds and higher spray rates.
•
The agitator normally remains switched on from filling to the end
of spraying operation. On this account, the instructions of the
agent manufacturer are decisive.
•
If there is a sudden significant drop-off in spray pressure, the
spray liquid tank is empty.
•
Residues in the spray liquid tank can be applied correctly up to a
pressure drop of 25%.
•
If the spray pressure drops off while conditions remain otherwise
unaltered, the suction or pressure filter is blocked.
10.7.1
Applying the spray liquid
•
Properly couple the field sprayer to the tractor.
•
Before starting spraying, check the following machine data on
the operating terminal
ο
the values for the permitted spray pressure range of the
spraying nozzles installed in the sprayer boom.
ο
the value "Pulses per 100m".
•
Take the appropriate action if a fault message appears on the
display during spraying.
•
Check the indicated spray pressure during spraying operation.
Ensure that the indicated spray pressure does not deviate under
any circumstances by more than
±
25 % from the target spray
pressure given in the spray table, e.g. by changing the spray
rate using the plus/minus buttons. Larger deviations than this
from the target spray pressure make it impossible to achieve the
best possible results from your crop protection measure and
cause pollution of the environment.
Decrease or increase the operational speed until you are back
within the permissible spray pressure range for the target spray
pressure.
