Precision X-axis positioning is by rotating a knurled hand wheel with a hand crank, as shown in
Figures 1 and 2. The stage can be disengaged from the shaft of the hand wheel by raising the
lever of a latch block around the shaft, thereby allowing the stage to be pushed directly by hand
for coarse X-axis positioning. The stage is reengaged to the shaft by lowering the lever of the
latch block.
Y-axis positioning is via the large hand crank at the base of the unit, as shown in Figures 1 and 2.
Rotate clockwise to raise the stage, counterclockwise to lower the stage.
The stage can be rotated by ±15° around a vertical axis to provide skew adjustment for parts
that are not perfectly aligned with the stage. The skew angle can be read to a precision of 10’
by means of a Vernier scale. To release the stage for skew adjustment, first release the locking
levers at the right and left of the rotation mechanism that supports the stage. Turn the levers
