INSTALLING DRILL BIT IN CHUCK (FIG. U)
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 (flutes) of the drill bit when
the jaws are tightened.
3. Make sure that the drill is centred in
the chuck.
4. Turn the chuck key (2) clockwise to
tighten the chuck jaws (1).
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."

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. V, W)
1. Make the depth mark (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 (1).
3. Hold the feed handle at this position.
4. Spin the lower nut (3) down to contact the
depth stop lug (4).
5. Spin the upper nut (5) down and tighten
against the lower nut (3).
6. The drill bit (2) now will stop after traveling
the distance marked on the workpiece.
Depth scale method (Fig. W)
NOTE: With the chuck in the upper position,
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 (6) points to the
desired depth on the depth scale (7) and
hold the feed handle in that position.
2. Spin the lower nut (3) down to contact the
depth stop lug (4).
3. Spin the upper nut (5) against the lower
nut (3) and tighten.
4. The drill bit will stop after traveling the
distance selected on the depth scale.

DRILL A HOLE
Using a centre punch or a sharp nail, make an
indentation in the workpiece where you want
to drill. Turn the power switch on and pull
down on the feed handles with only enough
effort to allow the drill to cut.
FEEDING TOO RAPIDLY might 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 metal drilling oil to prevent it
from overheating.
