Description of machine operation

5--9

At the end of the cutting operation, the head can be raised.

Remove the piece from the vice; in the MA version the vice is opened using

the open/close button, or by manually turning the vice handwheel.

If the machine is equipped with the Cut Control System, make sure that the

function selector switch is positioned on Manual and that the head return

spring is tensioned in the Manual position.
