ENGLISH

1. Use sharp drill bits only. For WOOD, use twist

drill bits, spade bits, power auger bits, or hole

saws. For METAL, use steel twist drill bits or

hole saws.

2. Always apply pressure in a straight line with the

bit. Use enough pressure to keep drill biting, but

do not push hard enough to stall the motor or

deflect the bit.

3. Hold tool firmly with both hands to control the

twisting action of the drill.

4. IF DRILL STALLS, it is usually because

it is being overloaded or improperly used.

RELEASE TRIGGER IMMEDIATELY, remove

drill bit from work, and determine cause of

stalling. DO NOT CLICK TRIGGER ON

AND OFF IN AN ATTEMPT TO START A

STALLED DRILL — THIS CAN DAMAGE

THE DRILL.

5. To minimize stalling or breaking through the

material, reduce pressure on drill and ease the

bit through the last fractional part of the hole.

6. Keep the motor running when pulling the bit

back out of a drilled hole. This will help prevent

jamming.

7. With variable speed drills there is no need to

center punch the point to be drilled. Use a

slow speed to start the hole and accelerate by

squeezing the trigger harder when the hole is

deep enough to drill without the bit skipping

out.

DRILLING IN METAL

Start drilling

with slow speed and increase to full

power while applying firm pressure on the tool.

A smooth even flow of metal chips indicates the

proper drilling rate. Use a cutting lubricant when

drilling metals. The exceptions are cast iron and

brass which should be drilled dry.

NOTE:

Large [5/16" (8 mm)] holes in steel can

be made easier if a pilot hole [5/32" (4 mm)] is

drilled first.

DRILLING IN WOOD

Start drilling with slow speed and increase to full

power while applying firm pressure on the tool.

Holes in wood can be made with the same twist

drills used for metal. These bits may overheat unless

pulled out frequently to clear chips from the

flutes.

Work that is apt to splinter should be backed up

with a block of wood.

Keyed Chuck

(ﬁg. 3, 4)

The DWD014 features a keyed chuck (d). To insert

a drill bit or other accessory, follow the steps listed

below.

1. Open the chuck jaws by turning collar by hand

and insert the shank of the bit about 3/4"

(19 mm) into chuck. Tighten the chuck collar by

hand.

2. Place chuck key in each of the three holes, and

tighten in clockwise direction. It’s important to

tighten chuck with all three holes.

To release the bit, turn the chuck counterclockwise

in just one hole, then loosen the chuck by hand.

REMOVAL OF KEYED CHUCK (FIG. 3)

Tighten the chuck around the shorter end of a hex

key (not supplied) of 1/4" (6 mm) or greater size.

Using a soft hammer,

strike the key sharply in the

counterclockwise direction when viewed from the

front of the tool. This will loosen the chuck so that it

can be removed by hand.

KEYED CHUCK INSTALLATION (FIG. 4)

Screw the chuck on by hand as far as it will go.

Insert the shorter end of a hex key (not supplied)

of 1/4" (6 mm) or greater size and strike it in the

clockwise direction with a soft hammer.

MAINTENANCE

Your DEWALT power tool has been designed to

operate over a long period of time with a minimum

of maintenance. Continuous satisfactory operation

depends upon proper tool care and regular cleaning.

WARNING: To reduce the risk of

injury, turn unit off and disconnect

machine from power source before

installing and removing accessories,

before adjusting or changing set-ups

or when making repairs. Be sure the

trigger switch is in the OFF position. An

accidental start-up can cause injury.
