If the table is not parallel to the boring head, drilled
holes will be at an angle or at different depths.
To check and adjust the table parallel to the
boring head:
1. DISCONNECT THE BORING MACHINE
FROM POWER!
2. Use a dial indicator or a planed piece of
stock to measure the distance between the
table and boring head at the four corners of
the boring head (refer to the
X's illustrated in
Figure 36).
— If these distances are not equal, the table
and boring head are not parallel to one
another. Continue to
Step 3.
— If these distances are equal, the table and
boring head are parallel, and no further
adjustments are necessary.

and boring head parallelism (top view).
3. Loosen the cap screws that secure the cross
fence (see
Figure 37), and shim between the
mounting bracket and the cross fence.
4. Re-tighten the cross fence cap screws, and
re-check the parallelism of the table and
boring head. Repeat this procedure if neces-
sary.
