KEYLESS SINGLE SLEEVE CHUCK (FIG. 7–9)
DCD940, DCD930, DCD920
Your tool features a keyless chuck with one rotating
sleeve for one-handed operation of the chuck. To
insert a drill bit or other accessory, follow these
steps.
1. Lock the trigger in the OFF position. Turn off
tool and disconnect tool from power source.
2. Grasp the black sleeve of the chuck (d) with
one hand and use the other hand to secure the
tool as shown in Figure 7. Rotate the sleeve
counterclockwise (as viewed from the front) far
enough to accept the desired accessory.
3. Insert the accessory about 3/4" (19 mm) into
the chuck and tighten securely by rotating the
chuck sleeve clockwise with one hand while
holding the tool with the other hand. Continue
to rotate the chuck sleeve until several ratchet
clicks are heard to ensure full gripping power.
To release the accessory, repeat Steps 1 and 2
above.
Be sure to tighten chuck with one hand on the
chuck sleeve and one hand holding the tool for
maximum tightness.
SELF-TIGHTENING CHUCK OPERATION (FIG. 10–12)
DCD945, DCD935, DCD925
To insert a drill bit or other accessory:
1. Lock the trigger in the OFF position. Turn off
tool and disconnect tool from power source.
2. Grasp the chuck sleeve (m) with one hand and
use the other hand to secure the tool as shown
in Figure 10. Rotate the sleeve counterclockwise
(as viewed from the front) far enough to accept
the desired bit or accessory.
3. Insert the bit or other accessory about 3/4"
(19 mm) into the chuck, as shown in Figure 11.
Grasp the chuck sleeve (m) securely and rotate
the sleeve clockwise (viewed from the front) with
one hand while using the other hand to secure
the tool. Rotate the sleeve clockwise until sleeve
cannot be rotated any further, as demonstrated
in Figure 12. As the drill is being operated in
the forward position, the chuck will continually
self tighten the jaws of the chuck onto the bit or
accessory to maximize the bit gripping strength.
To release the accessory, repeat Steps 1 and 2.
OPERATION
Instructions for Use
WARNING: Always observe the safety
instructions and applicable regulations.
WARNING: To reduce the risk
of serious personal injury, turn
tool off and disconnect tool from
power source before making any
adjustments or removing/installing
attachments or accessories.
Proper Hand Position (fi g. 13)
WARNING: To reduce the risk of
serious personal injury, ALWAYS
use proper hand position as shown
in figure 13.

Drill Operation
1. Select the desired speed/torque range using
the gear shifter to match the speed and torque
to the planned operation. Set the mode control
collar to the drill symbol.
2. For WOOD, use twist bits, spade bits, power
auger bits or hole saws. For METAL, use high-
speed steel twist drill bits or hole saws. Use
a cutting lubricant when drilling metals. The
exceptions are cast iron and brass which should
be drilled dry.
3. Always apply pressure in a straight line with the
bit. Use enough pressure to keep the drill bit
biting, but do not push hard enough to stall the
motor or deflect the bit.
4. Hold tool firmly with both hands to control the
twisting action of the drill.
5. IF DRILL STALLS, it is usually because it
is being overloaded. RELEASE TRIGGER
IMMEDIATELY, remove drill bit from work,
and determine cause of stalling. DO NOT
CLICK TRIGGER OFF AND ON IN AN
ATTEMPT TO START A STALLED DRILL –
THIS CAN DAMAGE THE DRILL.
6. Keep the motor running when pulling the bit
back out of a drilled hole. This will help prevent
jamming.
Screwdriver Operation (fi g. 4–6)
1. Select the desired speed/torque range using the
three-speed gear shifter (g) on the top of tool
to match the speed and torque to the planned
application. Initially set the torque adjustment
