A WARNING
To prevent the workpiece or backup material from being
torn from your hands while drilling, you MUST position the
workpiece against the LEFT side of the column. If the
workpiece or the backup material is not long enough to
reach the column, clamp them to the table, or use the fence
provided with the drill press to brace the workpiece. Failure
to secure the workpiece could result in personal injury.
USING THE FENCE (FIG. W)
The fence provides a way of accurately and quickly
setting up the workpiece for more precision or repetitive
drilling operations.
1. Using the centerpunch or sharp nail, make an
indentation in the workpiece where you want to drill.
2. Lower the drill bit to align with the indentation on the
workpiece. See “HOLDING A DRILLING LOCATION”
page 19.
3. Loosen the knobs (1) and slide the fence back stop (2)
firmly against the long side of the workpiece. Tighten
the knobs when in position.
4. Loosen the wing nut (3) and slide the end stop (4) along
the fence until it is firmly against the left side of the
workpiece. Tighten the wing nut.
5. Check the accuracy by drilling a scrap workpiece.
Adjust if needed.
5. Hold with your hand or clamp the top surface of the
workpiece firmiy to prevent it from lifting off the table
when the bit is raised.

DRILLING TO A SPECIFIC DEPTH
Drilling a blind hole {not ail the way through workpiece)
to a given depth can be done two ways;
Workpiece method (FIG. X and Y)
1. Mark the depth of the hole on the side of the
workpiece (1),
2. With the switch “OFF”, bring the drill bit (2) down
until the tip is even with the mark.
3. Hold the feed handle at this position.
4. Spin the lower nut (3) down to contact the depth stop
lug (6) on the head.
5. Spin the upper nut (5) down and tighten against the
lower nut. (3)
6. The drill bit will now stop after traveling the distance
marked on the workpiece.
Depth scale method (FIG.Y)
NOTE: With the chuck up, the tip of the drill bit must be
just slightly above the top of the workpiece.

4.
With the switch “OFF", turn_the feed handle until
the pointer (7) points to the desired depth on the
depth scale (4). Hold the feed handles in that position.
Spin the lower nut (3) down to contact the depth stop
lug (6) on the head.
Spin the upper stop nut (5) against the lower stop nut
and tighten.
The and drill bit will now stop after traveling the
distance selected on the depth scale.
Drilling a hole
Using a center punch or a sharp nati, dent the workpiece
where you want the hole. Before turning the switch on,
bring the drill bit down to the workpiece, lining it up with
the hole location. Turn the switch on and pull down on
the feed handles with only enough effort to allow the drill
to cut.
FEEDING TOO SLOWLY might cause the driii bit to turn.
FEEDING TOO RAPIDLY might stop the motor, cause the
belt or drill to slip, tear the workpiece loose, or break the
drill bit. When drilling metal, it will be necessary to
lubricate the tip of the drill bit with oil to prevent it from
overheating.
