OPERATION
Make sure that the drill is centred in INSTALLING DRILL BIT
IN CHUCK (FIG. S)
1. With the switch OFF and the yellow switch key removed,
open the chuck jaws (1) using the chuck key (2). Turn the
chuck key counter clockwise to open the chuck jaws (1).
2. Insert the drill bit into the chuck far enough to obtain maxi-
mum gripping by the jaws, but not far enough to touch the
spiral grooves (flutes) of the drill bit when the jaws are tight-
ened.
3. Make sure that the drill is centred in the chuck.
4. Turn the chuck key clockwise to tighten the jaws.
WARNING:
To avoid injury or accident by the chuck key eject-
ing 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.

DRILLING TO A SPECIFIC DEPTH
Drilling a blind hole (not all the way through workpiece) to a
given depth can be done two ways:
Workpiece method (Fig. U and V)
1. Mark the depth (1) of the hole on the side of the workpiece.
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 travelling the distance
marked on the workpiece.
Depth scale method (Fig. V)
Note: With the chuck up, 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 until the pointer
(7) points to the desired depth on the depth scale (4) and hold
the feed handle in that position.
2. Spin the lower nut (3) down to contact the depth stop lug (6).
3. Spin the upper nut (5) against the lower stop nut and tighten.
4. The drill bit will stop after travelling the distance selected
on the depth scale.
