Removal of Keyed Chuck (Fig. F)
Remove the left-handed chuck screw using a T25 torx wrench,
rotating clockwise to loosen. Tighten the chuck around the
shorter end of a hex wrench (not supplied) of 10 mm size. With
the tool braced securely, use a soft hammer and strike the hex
wrench 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. F)
Screw the chuck on by hand as far as it will go. Insert the shorter
end of a hex wrench (not supplied) of 10 mm size and strike it
in the clockwise direction with a soft hammer. Reinstall the left
handed clutch screw.
Worklight (Fig. A)

CAUTION: Do not stare into worklight. Serious eye
injury could result.
The worklight 9 is located on the foot of the tool. The worklight
is activated when the trigger switch is depressed, and will
remain on for a short time after the trigger switch is released.
If the trigger switch 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
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 battery pack
before making any adjustments or removing/
installing attachments or accessories. An accidental
start-up can cause injury.
Proper Hand Position (Fig. G)

WARNING: To reduce the risk of serious personal injury,
ALWAYS use proper hand position as shown.

WARNING: To reduce the risk of serious personal
injury, ALWAYS hold securely in anticipation of a
sudden reaction.
Always hold tool firmly with both hands in the proper position
for operation as shown.
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, 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 minimise 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: Large 8 mm to 13 mm holes in steel can be made easier
if a pilot hole 4 mm to 5 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.
MAINTENANCE
Your D WALT power tool has been designed to operate
e
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 serious personal
injury, turn tool off and disconnect battery pack
before making any adjustments or removing/
installing attachments or accessories. An accidental
start-up can cause injury.
The charger and battery pack are not serviceable.
Lubrication
Your power tool requires no additional lubrication.
Cleaning

WARNING: Blow dirt and dust out of the main housing
with dry air as often as dirt is seen collecting in and around
the air vents. Wear approved eye protection and approved
dust mask when performing this procedure.

WARNING: Never use solvents or other harsh chemicals
for cleaning the non-metallic parts of the tool. These
chemicals may weaken the materials used in these parts.
