INSTALLATION
MOTO MAN 4-21 MH–Series Positioner Manual with MotoMount
The vertical alignment is checked by measuring the gap between the mounting
fixture and mounting block. The measurement of this gap must not change more
than 1 mm (.039 in.) after the headstock is rotated 180 degrees. To align
MotoMount vertically, proceed as follows:
1. Jog the positioner to a vertical position until the drive bushing is at the
bottom (see Figure 4-24).
2. Using calipers, measure the alignment gap.
NOTE: It is important to measure the alignment gap at the same location. This will ensure a proper
alignment.
3. Rotate the positioner 180 degrees until the drive bushing is at the top (see
Figure 4-25).
4. Measure the alignment gap at the second position. If the gaps are different by
more than 1 mm (.039 in.), the vertical alignment must be adjusted. Use the
following procedure to adjust the vertical alignment:
a) Calculate the average gap between the two positions by adding both mea-
surements together and dividing by two.
b) If the first measurement (with drive bushing at the bottom) is greater
than the second measurement, raise the headstock until the gap is at the
average gap value. Raise the headstock by making equal clockwise turns
on the headstock leveling bolts.
c) If the first measurement (with drive bushing at the bottom) is less than
the second measurement, the raise the tailstock until the gap is at the
average gap value. Raise the tailstock by making equal clockwise turns
on the tailstock leveling bolts.
