Table Adjustment
Refer to Figure 8.
The table can be raised or lowered to
accommodate the height of the workpiece. To
raise or lower the table, loosen the table lock
using the hand crank. Then use the hand crank
to move the table to the desired height. Then
lock the table in position.

Radial Head Adjustment (All Models)
Change the radial position of
the drill head only if the drill press base is
secured to the floor. Swinging the drill head
without the base being secured to the floor
will cause the drill press to become unstable
and tip over resulting in injury and/or
damage to the machine.
The radial position of the drill head can be
changed to accommodate the drilling of a hole
that may be offset from the center of the table.
Reposition the drill head as follows:
1. Loosen the two clamping hex nuts using the
hex socket wrench provided with the
machine.
2. The swing the drill head to the desired
position.
3. Tighten the two clamping nuts.
Speed Pickup Adjustment (All Models)
1. Loosen screws securing speed pickup (ref.
68A, page 23) to plate (ref. 69A, page 23).
2. Adjust the speed pickup gap to
approximately 1/8-inch. Re-tighten screws.
3. Operate drill press to verify that speed
readout is operating correctly.
Operating Precautions
The following operating and safety precautions
must be observed in order to avoid harm to the
operator or damage to the drill press.
1. The head assembly must be locked to the
column so the thrust produced by drilling will
not force the head assembly up the column.
2.
The work table must be locked to the
column so it will not be forced down the
column.
3. Before drilling, release the quill lock nut to
permit free travel of the quill.
4. Be sure the belt is tightened to the proper
tension.
5. DO NOT start to drill the workpiece until
making certain the workpiece is held down
securely.
6. MAKE SURE THE DRIVE MOTOR IS
RUNNING BEFORE
turning the speed
control handwheel in either direction.
7. Point of operation protection is required for
maximum safety. This remains the
responsibility of the user/purchaser since
conditions differ between jobs.
8. Make sure the drill is secured in the spindle
or chuck before attempting to use the drill
press.
9. Make sure the spindle taper is clean and
free of burrs, scoring, and galling to assure
maximum gripping.
10. Lock the quill in position when using any
side-loaded tool.
