3. Align the calibration test trays (4) with the seed side feeder shaft by turning the crank (1)
to position 1A.
The crank position 1B is for the seed side and the centre position is for seeding.
4. Check that the calibration test trays are at the feeders and their lock (5) is turned to the
side.
5. Remove the cotter (6) of the fertiliser side from the feed shaft chain gear. If the machine is
equipped with a small seed hopper, remove the cotter of the small seed hopper (2).
6. Attach the calibration test crank (3) to the calibration test shaft. Turn the crank until an
even ow of fertiliser or seed comes out of all feeders. Empty the calibration test trays.
7. Rotate the shaft counterclockwise 1 round per second using the calibration test crank.
An area of 100 m² is obtained by turning the crank 22 rounds.
8. Pull out the calibration test trays and weigh the quantities they now contain.
The calibration test quantity obtained corresponds to the area of 100 m², so the
quantities for a hectare will be hundredfold.
If the weighing result does not match the desired quantity, adjust the length of
the roller in accordance with section 6.5.5. ADJUSTING THE WIDTH OF THE
FEEDER ROLLER.
9. Repeat the calibration test. Make sure that the result is sufficiently close to the target
quantity.
10. Replace the calibration test trays in the machine. Ensure that the trays are in the correct
order and that they are connected to each other correctly.
11. Reinsert the cotters.
12. Turn the crank to bring the calibration test trays to the seeding position.
13. Put the transmission cover back in place.
