1. Turn on table motor. Table should rotate in counter clockwise direction when viewed from
the top (see arrow label on edge of table). Turn on grinding motor. Motor should rotate in
clockwise direction when viewed from the top (see arrow label on front of motor).
2. If both the table motor and the grinding motor are rotating the wrong direction, interchange
any two of the three HOT LEADS of the 3 Phase connection at the electrical box (Figure

not the other, contact Van Norman technical assistance.
