13. CALIBRATION
Because the adjustment values in the sowing table are only indicative, before starting the sowing,
a calibration must be carried out. Before starting a calibration the machine will be adjusted
according to the sowing table.
Check:
•
Transmission cassette setting I / II
•
Bottom flaps position (seed and fertilizer)
•
Seed feed rate from the handwheel
•
That the optional drive groove device is not being used
•
The amount of fertilizer feed from the handwheel
•
The shutters are fully open
•
That the tanks contain fertilizer and seeds
Machine is slightly lifted from the ground, so that the ground-wheel is loose and can be rotated.
Rotating can be easily arrived at by inserting a rotation piece in its place as in Fig. 14. The rotation
piece referred to is located in the left end of the machine under a cover.
Machine tubes (both seed and fertilizer) can be easily set to a calibration position at the same
time. This takes place from the front of the machine (fig. 15).
•
Lift the lock up
•
Push the hose rack back
•
Ensure that the hose rack moves evenly and i.e. not another edge first.
Calibration can be done in three ways:
•
For the seeds and fertilizer simultaneously, when all of the transmission pins are in
place.
•
Separately for the seeds, when a spring ring pin is removed from the end of the
fertilizer shaft. Remember to place the pin back in place after the calibration
•
Separately for the fertilizer, when the seed side cassette pin is removed. Remember
to place the pin back in place after the calibration
