Operation - Craftsman 124.47747 Operator's Manual

1. Installing A Drill Bit
See Fig. 14
A. With the switch "OFF", open the chuck jaws (1) using the chuck key (2).
Turn the chuck key counterclockwise to open the chuck jaws (1).
B. 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.
C.
Make sure that the drill is centered in the chuck.
D. 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, always recheck and re-
move the chuck key before turning the power ON.
2. Positioning Workpiece
If not using a table fence, to prevent the workpiece or back-up material
from being torn from your hands while drilling, you MUST position it
against the LEFT side of the column. Failure to do this could result in
personal injury.
See Fig.15
3. Using Vise
For small workpieces that cannot be clamped to the table, use a drill press
vise. The vise must be clamped or bolted to the table.
WARNING: The drill press vise MUST be clamped or bolted to the table to
avoid injury from a spinning workpiece, or damaged vise or bit parts.
See Fig.16
4. Drilling a Hole
Using a center punch or a sharp nail, make an indentation in the workpiece
where you want to drill. Turn the power switch on and pull down 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 work-
piece 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
DRILLING TO A SPECIFIC DEPTH
Drilling a blind hole (not all the way through the workpiece) to a given depth
can be done two ways:
Workpiece method (Figure 16 and 17)
A. Mark the depth (2) of the hole on the side of the workpiece.(1) (Figure 16).
B. With the switch "OFF", bring the drill bit (2) down until the tip is even with
the mark (Figure 16).
C. Hold the feed handle at this position.
D. Spin the lower nut (3) down to contact the depth stop lug (6) on the head
(Figure 17).
E. Spin the upper nut (5) down and tighten against the lower nut
(3)(Figure 17).
F. The drill bit will now stop after traveling the distance marked on the work-
piece.
Depth scale method (Figure 17)
A. 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.
B. Spin the lower nut (3) down to contact the depth stop lug (6).
C. Spin the upper nut (5) against the lower stop nut and tighten.
D.The drill bit will stop after traveling the distance selected on the depth
scale.
