the calibration and exit the page.
NOTE:
This calibration procedure can also be done when the
machine is in normal operation; however, this will result in
more erratic knife speeds. Performing a deliberate
calibration prior to normal operation will make sure that
the calibration is automatically maintained and adjusted as
performance varies. This also ensures that the system
constantly or periodically monitors the relationship of the
engine speed, the knife speed, the valve current, and the
pressure.

calibrated to ensure that the knife drive pump output is accurate.
DANGER
Ensure that all bystanders have cleared the area.

This calibration MUST be performed with the engine running and the header engaged.
