The motor and chuck axis was set parallel with
the table by the factory. This ensures boring oper-
ations will be vertically squared in the workpiece
If boring holes are no longer perpendicular to
the workpiece, as shown in
Figure 41, refer to
Troubleshooting on Page 30 to rule out other
solutions first, then perform the following proce-
dure to reset table parallelism.

To verify table parallelism with chuck:
1. DISCONNECT MACHINE FROM POWER!
2. Clean and service chuck (refer to Hold-Down
Clamp & Chuck Jaws on Page 28).
3. Follow instructions in Adjusting Table Roller
Bearings on Page 33.
4. Mount drill rod (round, straight metal

diameter) in chuck. Rotate by chuck hand to
ensure rod is straight and doesn't wobble.
5. Raise table until there is approximately 1"
gap between table surface and bottom of drill
rod (see
Figure 42), then tighten table lock.
6. Set adjustable square against drill rod and
table at chuck end, as shown in
Figure 42,
then tighten square to secure measurement.
7. Move square to opposite end of drill rod to
check parallelism.
—If measurements at both ends of drill rod
are equal, no adjustment is necessary. The
chuck is parallel to the table.
—If measurements at both ends of drill rod
are not equal, the chuck is not parallel to
the table. Proceed to
Step 8.
