OPERATION
INSTALLING A DRILL BIT
1. With the switch OFF, open the chuck jaws (Fig. X - 1) using the chuck key
(Fig. X - 2). Turn the chuck key counterclockwise to open the jaws.
2. Insert the drill bit (Fig. X - 3) into the chuck far enough to obtain the maxi-
mum gripping by the jaws, but not far enough to touch the spiral grooves of
the drill bit when the jaws are tightened.
3. Make sure the drill is centered in the chuck. Turn the chuck key (Fig. X -
2) clockwise to tighten the jaws.
POSITION THE TABLE AND WORKPIECE
Always place a piece of backup material (wood, plywood, etc.) on the table
underneath the workpiece . This will prevent splintering on the underside
of the workpiece as the drill bit breaks through. To keep the material from
spinning out of control, it must contact the left side of the column, or be
clamped (not included) to the table.
To prevent the workpiece or back-up material from spinning or rotating, you
MUST position it against the left side of the column (Fig. Y).

Note: For small workpieces that cannot be clamped to the table, use a drill press vise (not included). The vise
must be clamped or bolted to the table to avoid injury.
GENERAL DRILLING GUIDELINES - DRILLING A HOLE
WARNING: To prevent the workpiece and the backup material from slipping from your hand while drilling, po-
sition the workpiece and backup material to the left side of the column. If the workpiece and the backup material
are not long enough to reach the column, clamp the workpiece and backup material to the table. Failure to do this
could result in personal injury.
1. Mark where you want to drill the workpiece by using a center punch or a sharp nail. Turn ON the laser to mark
your drilling point also.
2. Before turning the drill press ON, turn the feed handles to bring the drill bit down. Line the drill bit tip up with
the mark. Clamp the workpiece in place.
3. Turn ON the drill press and pull down on the feed handles with the appropriate force needed to allow the drill
bit to drill the material.
4. It is good practice to touch the bit to the surface before fully committing to the cut to mark the surface of your
work piece. This helps ensure a straighter cut/hole while maximizing accuracy.
5. Make sure to routinely retract the bit to remove shavings and wood chips from the hole in order to prevent the
drill bit from binding.
Note: Feeding too slowly might cause the drill bit to turn in the chuck. Feeding too rapidly
might stop the motor, cause the belt to slip, force the workpiece loose, or break the drill bit. Practice with scrap
material to get the feel of the machine before attempting to do any drilling operation.
