DRILLING TO A SPECIFIC DEPTH (Fig. V)
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. W)
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.

REMOVING CHUCK AND ARBOR (Fig. X)
1. With the switch "OFF" and the unit unplugged, adjust
the depth stop nut (1) to hold the drill at a depth of
three inches. (See instructions for "LOCKING CHUCK
AT DESIRED DEPTH").
2. Align the key holes in the spindle (2) and quill (3) by
rotating the chuck by hand.
3. Insert the key wedge (4) into the key holes (2 & 3).
4. Tap the key wedge (4) lightly with a plastic tipped
hammer, until the chuck and arbor fall out of the
spindle.
NOTE: Place one hand below the chuck to catch it
when it falls out.
