switch and remove the battery from the tool when
changing acces sories.

WARNING: Always ensure the bit is secure before
starting the tool. A loose bit may eject from tool
causing possible personal injury.
Open the keyed chuck 9
hand then insert the shank of the bit about 3/4" (19 mm)
into chuck. Tighten the chuck collar by hand. Place chuck
key ( 12 , Fig. A) 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.
NOTE: When using hex shank or three-sided shank bits, be
sure to align the flat sides of the bit with the chuck jaws to
ensure the bit is properly engaged by the jaws.
Worklight (Fig. A)

CAUTION: Do not stare into worklight. Serious eye
injury could result.
The worklight 6 is activated when the trigger is depressed,
and will remain on for a short time after the trigger is
released. If the trigger remains depressed, the worklight will
remain on.
NOTE: The worklight is for lighting the immediate work
surface and is not intended to be used as a flashlight.
OPERATION

WARNING: To reduce the risk of serious personal
injury, turn unit off and remove the battery pack
before making any adjustments or removing/
installing attachments or accessories. An
accidental start‑up can cause injury.
Installing and Removing the Battery Pack

it into the handle until the battery pack is firmly seated in the
tool and ensure that it does not disengage.
To remove the battery pack from the tool, press the release
button 2 and firmly pull the battery pack out of the tool
handle. Insert it into the charger as described in the charger
section of this manual.

Drilling

WARNING: TO REDUCE THE RISK OF PERSONAL
INJURY, ALWAYS ensure workpiece is anchored or
clamped firmly. If drilling thin material, use a wood
"back‑up" block to prevent damage to the material.

1. Use sharp drill bits only. For WOOD, use twist drill bits,
spade bits, auger bits, self-feed 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.
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: 7/16" (11 mm) holes in steel can be made easier if a
pilot hole [5/32" (4 mm) to 3/16" (5 mm)] is drilled first.
NOTE: When using a cutting lubricant, be sure not to get the
lubricant on the tool.
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.
MAINTENANCE

WARNING: To reduce the risk of serious personal
injury, turn unit off and remove the battery pack
before making any adjustments or removing/
installing attachments or accessories. An
accidental start‑up can cause injury.
Your D WALT power tool has been designed to operate
e
over a long period of time with a minimum of maintenance.
