INSTALLING A DRILL BIT IN THE CHUCK (FIG. R)
1. With the switch "OFF" and the safety key removed,
open the chuck jaws (1) using the chuck key (2).
Turn the chuck key counterclockwise to open the
chuck jaws (1).
2. Insert the drill bit (3) into the chuck far enough to
obtain maximum gripping by the jaws, but not far
enough to touch the spiral grooves (fl utes) of the drill
bit when the jaws are tightened.
3. Make sure that the drill is centered in the chuck.
4. Turn the chuck key clockwise to tighten the jaws.
WARNING
To avoid injury or accident by the chuck key ejecting
forcibly from the chuck when the power is turned "ON",
use only the self-ejecting chuck key supplied with this
drill press. ALWAYS recheck and remove the chuck key
before turning the power "ON".

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.
Failure to secure the workpiece could result in personal
injury.
DRILLING TO A SPECIFIC DEPTH (FIG. S)
Drilling a blind hole (not all the way through workpiece) to
a given depth can be done two ways:
Workpiece method
1. Mark the depth (1) of the hole on the side of the
workpiece.
2. With the switch "OFF", bring the drill bit down until the
tip is even with the mark.
3. Hold the feed handle (2) at this position.
4. Spin the lower nut (3) down to contact the depth stop
(4) 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
Note: With the chuck quill assembly fully retracted the
tip of the drill bit must be just slightly above the top of the
workpiece.
1. With the switch "OFF", turn the feed handle (2) until
depth stop (4) points to the desired depth on the
depth scale (6) and hold the feed handle in that
position.
2. Spin the lower nut (3) down to contact the depth stop
(4).
3. Spin the upper nut (5) against the lower stop nut (3)
and tighten.
4. The drill bit will stop after traveling the distance
selected on the depth scale.

LOCKING THE CHUCK AT THE DESIRED DEPTH
(FIG. T)
1. With the switch "OFF", turn the feed handles until
the chuck (1) is at the desired depth. Hold the feed
handles at this position.
2. Turn the stop nut (2), located under the depth stop
(3), counterclockwise and upwards, until it is against
the depth stop.
3. The chuck will now be held at this position when the
feed handles are released.
