Calibration Crank
Loss of Material Risk:
Do not open the door under the DRIVING gear. This is the
clean-out door. Opening this door drains the hopper. Once the
clean-out door is open it is difficult to stop seed flow until the
hopper is empty, and impossible to close it with a seal tight
enough for application.
Refer to Figure 8 or Figure 10
5.
Mount calibration crank:
ADC2350/B: onto clutch shaft. See “Meter Hand
Crank” in air cart Operator Manual for operations.
NTA907/3007/HD: onto contact drive shaft. See
“Calibration Crank” in Operator Manual for
operations.
Machine Damage and Rate Risks:
Rotate calibration crank only in the correct direction:
ADC2350/B:
COUNTERCLOCKWISE
NTA607/2007/HD COUNTERCLOCKWISE
NTA907/3007/HD: CLOCKWISE on left side, at contact
drive (as shown in Figure 10) or at
jackshaft (2012+ models),
COUNTERCLOCKWISE on right side
at contact drive
Operating in reverse can cause gearbox damage.
6. Turn the calibration crank enough turns to be sure
the meter flutes are full and the system is metering.
Possible Agricultural Chemical Hazards:
Obey manufacturer or grower recommendations for safety
equipment and protective gear when using treated seeds.
7. Wipe all material off the flanges around the meter
door.
