5. Set the metering slider stop to the value specified in the spreading table.
7. Start the tractor.
8. Set the PTO shaft speed according to the values in the fertiliser chart.
9. Open the left metering slide for the calibration test time stipulated before from
the tractor seat.
10. Close the metering slide when this time has elapsed.
11. Determine the fertiliser weight (taking into consideration the empty weight of
the collection vessel).
12. Compare the actual quantity with the target quantity.
Actual output quantity = target output quantity: output rate stop is set cor-
rectly. End calibration test.
Actual output quantity < nominal output quantity: Set the output rate stop
to a higher position and repeat the calibration test.
Actual output quantity > nominal output quantity: Set the output rate stop
to a lower position and repeat the calibration test.
n WARNING
Risk of injury due to rotating machine components
Rotating machine components (universal drive shaft, hubs) may
catch and pull-in body parts or objects. Contact with rotating
machine components may cause bruises, abrasions and crushing
injuries.
Always stay outside the area of rotating hubs while the
machine is running.
When the drive shaft is rotating, the metering slides are to
be operated from the tractor seat at all times.
Ensure that nobody is present in the hazard zone of the
machine.
6. Position a collection vessel
under the left output.
