Move the housing to position the drill bit over the center of the hole.
Tighten the adjusting handle securely.
Keyed Chuck (Fig. 9) (Select Models)
1. Open the chuck jaws wide enough to insert the bit. Be sure the
shank and the chuck jaws are clean. Dirt particles may prevent the
bit from lining up properly.
2. When using drill bits, insert the bit into the chuck. Center the bit in the
chuck jaws and lift it about 1/32" off of the bottom. Tighten the chuck
jaws by hand to align the bit.
3. Place the chuck key in each of the three holes in the chuck, turning
it clockwise as shown below. Tighten securely.
4. To remove the bit, insert the chuck key into one of the three holes in
the chuck and turn it counterclockwise.
- Clockwise (Tighten)
- Counterclockwise (Loosen)
Morse Taper Socket (Fig. 10) (Select Models)
These drills are supplied with a No. 3 Morse Taper Socket.
To insert a bit or adapter into the socket:
1. Make sure the taper is clean and lightly oiled. Foreign material can
cause misalignment.
2. Insert the taper into the socket and rotate the taper until the bit tang
slides into the slot at the top of the socket.
3. Press the taper firmly into the socket, or use the feed handle to press
the bit against a piece of wood.
To remove a bit or adapter from the socket:
1. Unscrew the knurled collar and remove the entire Morse Taper Socket.
2. Strike the bit tang firmly with a soft metal mallet or strike the bit tang
firmly on a wood or soft metal surface.
3. Replace the Morse Taper Socket by aligning the notches with tabs
on the drill.
4. Replace the knurled collar and tighten.

Gear Shift Lever (Fig. 7)
Cat. Nos. 4292-1 and 4297-1 operate in either high or low speed. Use low
speed for large diameter bits and high speed for small diameter bits (see
Specifications chart).
To change speeds, turn the drill off and rotate the lever up or down while
the drill is coasting to a stop.
NOTE: To avoid damage to the gearbox, do not shift at full speed, when
the tool is under load, or when the tool has stopped.

If a loss of line voltage occurs while the drill is running, the drill will
stop.
