• Do not place any object on top of charger or place the charger on a soft surface that
might block the ventilation slots and result in excessive internal heat. Place the charger
in a position away from any heat source. The charger is ventilated through slots in the top
and the bottom of the housing.
• Do not operate charger with damaged cord or plug.
• Do not operate charger if it has received a sharp blow, been dropped, or otherwise
damaged in any way. Take it to an authorized service center.
• Do not disassemble charger; take it to an authorized service center when service or
repair is required. Incorrect reassembly may result in a risk of electric shock, electrocution or
fire.
• Disconnect the charger from the outlet before attempting any cleaning. This will
reduce the risk of electric shock. Removing the battery pack will not reduce this risk.
• NEVER attempt to connect 2 chargers together.
• The charger is designed to operate on standard 120V household electrical power. Do
not attempt to use it on any other voltage. This does not apply to the vehicular charger.
Using Automatic Tune-Up™ Mode
The automatic Tune-Up™ Mode equalizes or balances the individual cells in the battery pack
allowing it to function at peak capacity. Battery packs should be tuned up weekly or after
10 charge/discharge cycles or whenever the pack no longer delivers the same amount of work.
To use the automatic Tune-Up™, place the battery pack in the charger and leave it for at least
8 hours. The charger will cycle through the following modes.
1. The red light will blink continuously indicating that the 1-hour charge cycle has started.
2. When the 1-hour charge cycle is complete, the light will stay on continuously and will no
longer blink. This indicates that the pack is fully charged and can be used at this time.
3. If the pack is left in the charger after the initial 1-hour charge, the charger will begin the
Automatic Tune-Up™ mode. This mode continues up to 8 hours or until the individual cells
in the battery pack are equalized. The battery pack is ready for use and can be removed at
any time during the Automatic Tune-Up™ mode.
4. Once the Automatic Tune-Up™ mode is complete, the charger will begin a maintenance
charge; the red indicator will remain lit.
Chargers
Your tool uses a D WALT 12, 14,4 or 18 volt charger. Be sure to read all safety instructions
E
before using your charger. Consult the chart at the end of this manual for compatibility of
chargers and battery packs.
Charging Procedure
DANGER: Electrocution hazard. 120 volts present at charging terminals. Do not probe with
conductive objects. Danger of electric shock or electrocution.
1. Plug the charger into an appropriate outlet before inserting battery pack.
2. Insert the battery pack into the charger. The red (charging) light will blink continuously
indicating that the charging process has started.
3. The completion of charge will be indicated by the red light remaining ON continuously. The
pack is fully charged and may be used at this time or left in the charger.
Indicator Light Operation
Charge Indicators
Some chargers are designed to detect certain problems that can arise with battery packs.
Problems are indicated by the red light flashing at a fast rate. If this occurs, re-insert battery pack
into the charger. If the problem persists, try a different battery pack to determine if the charger is
OK. If the new pack charges correctly, then the original pack is defective and should be returned
to a service center or other collection site for recycling. If the new battery pack elicits the same
trouble indication as the original, have the charger tested at an authorized service center.
HOT/COLD PACK DELAY
Some chargers have a Hot/Cold Pack Delay feature: when the charger detects a battery that is
hot, it automatically starts a Hot Pack Delay, suspending charging until the battery has cooled.
After the battery has cooled, the charger automatically switches to the Pack Charging mode.
This feature ensures maximum battery life. The red light flashes long, then short while in the
Hot Pack Delay mode.
PROBLEM POWER LINE
Some chargers have a Problem Power Line indicator. When the charger is used with some
portable power sources such as generators or sources that convert DC to AC, the charger may
temporarily suspend operation, flashing the red light with two fast blinks followed by a
pause. This indicates the power source is out of limits.
LEAVING THE BATTERY PACK IN THE CHARGER
The charger and battery pack can be left connected with the red light glowing indefinitely. The
charger will keep the battery pack fresh and fully charged.
NOTE: A battery pack will slowly lose its charge when kept out of the charger. If the battery pack
has not been kept on maintenance charge, it may need to be recharged before use. A battery
pack may also slowly lose its charge if left in a charger that is not plugged into an appropriate
AC source.
WEAK BATTERY PACKS: Chargers can also detect a weak battery pack. Such batteries are
still usable but should not be expected to perform as much work. The charger will indicate to
replace battery pack.
Important Charging Notes
1. Longest life and best performance can be obtained if the battery pack is charged when the
air temperature is between 65°F and 75°F (18°- 24°C). DO NOT charge the battery pack in
an air temperature below +40°F (+4.5°C), or above +105°F (+40.5°C). This is important and
will prevent serious damage to the battery pack.
2. The charger and battery pack may become warm to touch while charging. This is a normal
condition, and does not indicate a problem. To facilitate the cooling of the battery pack after
use, avoid placing the charger or battery pack in a warm environment such as in a metal
shed, or an uninsulated trailer.
3. If the battery pack does not charge properly:
a. Check current at receptacle by plugging in a lamp or other appliance;
b. Check to see if receptacle is connected to a light switch which turns power off when you
turn out the lights;
c. Move charger and battery pack to a location where the surrounding air temperature is
approximately 65°F - 75°F (18°- 24°C);
d. If charging problems persist, take the tool, battery pack and charger to your local service
center.
4. The battery pack should be recharged when it fails to produce sufficient power on jobs which
were easily done previously. DO NOT CONTINUE to use under these conditions. Follow the
charging procedure. You may also charge a partially used pack whenever you desire with
no adverse affect on the battery pack.
5. Under certain conditions, with the charger plugged into the power supply, the exposed
charging contacts inside the charger can be shorted by foreign material. Foreign materials
of a conductive nature such as, but not limited to, grinding dust, metal chips, steel wool,
aluminum foil, or any buildup of metallic particles should be kept away from charger cavities.
Always unplug the charger from the power supply when there is no battery pack in the cavity.
Unplug charger before attempting to clean.
6. Do not freeze or immerse charger in water or any other liquid.
WARNING: Shock hazard. Don't allow any liquid to get inside charger. Electric shock may
result.
CAUTION: Never attempt to open the battery pack for any reason. If the plastic housing of the
battery pack breaks or cracks, return to a service center for recycling.
Storage Recommendations
1. The best storage place is one that is cool and dry away from direct sunlight and excess heat
or cold.
2. Long storage will not harm the battery pack or charger. Under proper conditions, they can
be stored for 5 years or more.
SAVE THESE INSTRUCTIONS FOR FUTURE USE
Motor
Your D WALT tool is powered by a D WALT-built motor. Be sure your power supply agrees
E E
with the nameplate markings.
Voltage decrease of more than 10% will cause loss of power and overheating. All D

Variable Speed Paddle Switch (Fig. 3)
To turn the tool on, squeeze the paddle switch (A). To turn the tool off, release the paddle
switch. Your tool is equipped with a brake. The chuck will stop as soon as the paddle switch is
fully released.
The variable speed switch enables you to select the best speed for a particular application. The
farther you squeeze the paddle, the faster the tool will operate. Use lower speeds for starting
holes without a centerpunch, drilling in metals or plastics, driving screws and drilling ceramics,
or in any application requiring high torque. Higher speeds are better for drilling in wood, wood
compositions and for using abrasive and polishing accessories. For maximum tool life, use vari-
able speed only for starting holes or fasteners.
NOTE: Continuous use in variable speed range is not recommended. It may damage the switch
and should be avoided.

Keyless Chuck
Your tool features a 3/8" keyless chuck for greater convenience. To insert a drill bit or other
accessory, follow the steps listed below.
1. Lock the trigger switch in the off position as described earlier.
2. Grasp the rear half of the chuck with one hand and use your other hand to rotate the front
half counterclockwise. Rotate far enough so that the chuck opens sufficiently to accept the
desired accessory.
3. Insert the bit or other accessory about 3/4" into the chuck and tighten securely by holding
the rear half of the chuck and rotating the front portion in the clockwise direction.
To release the accessory, repeat step 2 listed above.
WARNING: Do not attempt to tighten drill bits (or any other accessory) by gripping the front
part of the chuck and turning the tool on. Damage to the chuck and personal injury may result.
Always lock off trigger switch when changing accessories.
Be sure to tighten chuck with two hands on both the rear sleeve and the forward sleeve for
maximum tightness.
Chuck Removal
WARNING: Always use eye protection. All users must wear eye protection that conforms to
ANSI Z87.1.
Move the shifter to position 1. Tighten the chuck around the shorter end of a hex key (not sup-
plied) of 1/4" or greater size. Using a wooden mallet or similar object, strike the longer end in the
clockwise direction, as shown in Fig. 4. This will loosen the screw inside the chuck.
Open chuck jaws fully, insert screwdriver (or Torx tool if required) into front of chuck between
jaws to engage screw head. Remove screw by turning clockwise (left-hand-thread). Place hex
key in chuck and tighten, as shown in Fig. 4. Using a wooden mallet or similar object, strike key
sharply in the counterclockwise direction. This will loosen the chuck so that it can be unscrewed
by hand.
Chuck Installation
Screw the chuck on by hand as far as it will go and insert screw (LH thread). Tighten screw
securely. Tighten the chuck around the shorter end of a 1/4" or larger hex key (not supplied)
strike the longer end in the clockwise direction with a wooden mallet, as shown in Fig. 4. Tighten
the screw once again by turning in a counterclockwise direction.
Operation as a Drill
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.
WARNING: To reduce the risk of personal injury, ALWAYS operate the tool with the side
handle properly installed. Failure to do so may result in the side handle slipping during tool
operation and subsequent loss of control. Hold tool with both hands to maximize control.
Install and tighten the desired drill bit in the chuck. Select the desired speed/torque range using
the dual range gear shifter to match the speed and torque to the planned operation. Follow these
instructions for best results when drilling.
Turn the collar to the drill bit symbol. Install and tighten the desired drill bit in the chuck. Select
the desired speed/torque range using the gear shifter to match the speed and torque to the
planned operation. Follow these instructions for best result s when drilling.
DRILLING
1. Use sharp drill bits only. For WOOD, use the low speed setting and twist drill bits, spade bits,
power auger bits, or hole saws. For METAL, use the low speed setting and 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. If model is not
equipped with side handle, grip drill with one hand on the handle and one hand on the battery
pack.
CAUTION: Drill may stall if overloaded causing a sudden twist. Always expect the stall. Grip
the drill firmly to control the twisting action and avoid injury.
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 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.
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) to 1/2" (13 mm)] holes in steel can be made easier if a pilot hole
[5/32" (4 mm) to 3/16" (5 mm)] is drilled first.
SCREWDRIVER OPERATION
Select the desired speed/torque range using the dual range gear shifter on the top of tool to
match the speed and torque to the planned operation.
Insert the desired fastener accessory into the chuck as you would any drill bit.
