Calibration Crank Safety Information
Moving Chain Hazard:
Keep all persons except operator away from drill mainframe
during crank operations. Body parts and clothing can get
caught in chains, sprockets and gears, causing serious injury.
When operating the crank from either side of the drill, all parts
of the contact drive system are in motion, including parts out
of sight of the crank operator.
Rotate the hand crank only in the:
clockwise direction on the left side, or
counter-clockwise direction on right side.
Operating in reverse can damage meter gear box.
Note: If a variable rate gearbox is set to “0”, operating the
hand crank may fail to clear the meters of seed.
Crank General Information
Refer to Figure 65
A hand crank is provided on the left side of the drill for
manual operation of the meters (the meters otherwise
turn only when the drill is lowered and in motion).
The crank is used for two common tasks:
• calibration of the meter setting for planting, and
• clean-out of the meter flute chamber.
