Refer to Figure 51
22. Press FUNCTION. The console beeps and displays
this screen, indicating that the drive is about to oper-
ate, and all personnel must be cleared from the area
near the hydraulic drive, chains and shafts. There is
a danger of entanglement if anyone is in the drive
area.
Moving Chain Entanglement Hazard:
Be sure to verify that no one is near the drive area before
advancing to the next step.
Refer to Figure 52
23. Move the hydraulic motor circuit level lever forward to
supply oil to motor.
24. Only after you have verified the drive area is clear,
press the up arrow button to initiate calibration mode.
The console beeps again.
If drive area isn’t clear, press Down arrow button to
abandon the calibration. This skips to the next item
in the main FUNCTION menu rotation (speed cali-
bration, page 51).
25. Continuing to verify that the drive area is clear, press
the ENGAGE button to start drive rotation.
To terminate priming, press ENGAGE.
Refer to Figure 53
26. While the drive is rotating, the display window shows
the time remaining and the “Out” rate.
The “out=” rate is the estimated area planting rate,
based on motor performance, and is not related to
the sample size. The example screen at right is half-
way through the priming, and the actual motor rate is
slightly high.
CONTINUE TO MONITOR DRIVE AREA DURING DRIVE
ROTATION. PRESS THE
ENGAGE BUTTON (OR OFF
KEY) TO STOP DRIVE DURING CALIBRATION
