either side of the tool using only the screw
accommodate left- or right- handed users. If the hook or bit clip
is not desired at all, it can be removed from the tool.
To move belt hook or bit clip, remove the screw

securely tighten the screw.
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. I)

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

WARNING: To reduce the risk of serious personal injury,
ALWAYS hold securely in anticipation of a sudden
reaction.
Proper hand position requires one hand on the main handle
14 , with the other hand on the side handle
Drill Operation (Fig. C)

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.

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. 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

6. Keep the motor running when pulling the bit back out of a
drilled hole. This will help prevent jamming.
Screwdriver Operation (Fig. D)
1. Select the desired speed/torque range using the three-
speed gear shifter on the top of tool to match the speed
7
and torque to the planned application. Initially set the
torque adjustment collar 5
fastener to be set to your specification.
nOTE: Use the lowest torque setting required to seat the
fastener at the desired depth. The lower the number, the
lower the torque output.
2. Rotate the mode control collar
aligned with the arrow.
3. Reset the torque adjustment collar
number setting for the torque desired. Make a few practice
runs in scrap or unseen areas to determine the proper
position of the torque adjustment collar.
nOTE: The torque adjustment collar may be set to any
number at any time. However, the torque adjustment collar is
only engaged during screwdriving mode and not in drill and
hammerdrill modes.
Hammerdrill Operation (Fig. E)
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
2. When drilling, use just enough force on the hammer to keep
it from bouncing excessively. Too much force will cause
slower drilling speeds, overheating, and a lower drilling rate.
3. Drill straight, keeping the bit at a right angle to the work. Do
not exert side pressure on the bit when drilling as this will
cause clogging of the bit flutes and a slower drilling speed.
4. When drilling deep holes, if the hammer speed starts to
drop off, pull the bit partially out of the hole with the tool
still running to help clear debris from the hole.
5. For masonry, use carbide-tipped bits or masonry bits. A
smooth, even flow of dust indicates the proper drilling rate.
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.
