• 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 charg-
er 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 — have them replaced immediately.
• 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 household electrical power (120
Volts). Do not attempt to use it on any other voltage. This does not apply to the
vehicular charger.

FOR FUTURE USE
Chargers
Your tool uses a 12.0, 14.4,18.0 Volt D WALT Charger. Your battery can be charged in D
E
1 Hour Chargers, 15 Minute Chargers or Vehicular 12 volt charger. Be sure to read all safety
instructions before using your charger. Consult the chart on the back cover 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 indi-
cating 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.
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.
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 elic-
its 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. Such batteries are still
usable but should not be expected to perform as much work. In such cases, about 10 seconds
after battery insertion, the charger will beep rapidly 8 times to indicate a weak battery condi-
tion. The charger will then go on to charge the battery to the highest capacity possible.
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, 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. Do not 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.
OPERATION
Variable Speed Switch
To turn the tool on, squeeze the trigger switch. To turn the tool off, release the trigger switch.
Your tool is equipped with a brake. The chuck will stop as soon as the trigger switch is fully
released.
NOTE: Continuous use in variable speed range is not recommended. It may damage the switch
and should be avoided.
Forward/Reverse Control Button (Fig. 1)
A forward/reverse control button determines the direction of the tool and also serves as a lock
off button. To select forward rotation, release the trigger switch and depress the
forward/reverse control button on the right side of the tool. To select reverse, depress the for-
ward/reverse control button on the left side of the tool. The center position of the control but-
ton locks the tool in the off position. When changing the position of the control button, be sure
the trigger is released.
NOTE: The first time the tool is run after changing the direction of rotation, you may hear a click
on start up. This is normal and does not indicate a problem.
Torque Adjustment Collar (Fig. 2)
The torque adjustment collar (A) is clearly marked with numbers and a drill bit symbol.The col-
lar should be rotated until the desired setting is located at the top of the tool (Fig. 2). Locators
are provided in the collar to eliminate the guess work when selecting fastening torque. The high-
er the number on the collar, the higher the torque and the larger the fastener which can be dri-
ven. To lock the clutch for drilling operations, move to the drill bit position.

NOTE: When using the Drill/Driver for drilling holes, be sure that the Torque Adjusting Collar is
set so the figure of the drill is aligned with the center line on the top of the tool. Failure to do this
will allow the clutch to slip while attempting to drill.
Dual Range Gearing (Fig. 3)
The dual range feature of your Driver/Drill allows you to shift gears for greater versatility.
To select the low speed, high torque setting, turn the tool off and permit to stop. Slide the gear
shifter forward (towards the chuck) as shown in Figure 3. To select the high speed, low torque
setting, turn the tool off and permit to stop. Slide the gear shifter back (away from chuck).
NOTE Do not change gears when the tool is running. If you are having trouble changing gears,
make sure that the dual range gear shifter is either completely pushed forward or completely
pushed back.
Keyless Single Sleeve Chuck
Your tool features a keyless chuck with one rotating sleeve for one-handed operation of the
chuck. To insert a drill bit or other accessory, follow these steps.
1. Lock the trigger in the OFF position as previously described.
2. Grasp the black sleeve of the chuck with one hand and use the other hand to secure the
tool. Rotate the sleeve counterclockwise far enough to accept the desired accessory.
3. Insert the accessory about 3/4" (19 mm) into the chuck and tighten securely by rotating the
chuck sleeve clockwise with one hand while holding the tool with the other. Your tool is
equipped with an automatic spindle lock mechanism. This allows you to open and close the
chuck with one hand.
To release the accessory, repeat step 2 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 one hand on the chuck sleeve and one hand holding the tool for
maximum tightness.
Operation as a Drill
DRILLING
1. To install the battery pack into the tool handle, align the base of the tool with the notch inside
the tool's handle and slide the battery pack firmly into the handle until you hear the lock snap
into place.
NOTE: To remove the battery pack from the tool, press the release buttons and firmly pull
the battery pack out of the tool handle.
2. Turn the collar to the drill bit symbol for drilling.
3. Select the desired speed/torque range using the gear shifter to match the speed and torque
to the planned operation.
4. 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.
5. 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.
6. Hold the drill firmly with one hand on the grip and the other hand on the bottom of the bat-
tery pack to control its twisting action.
7. IF DRILL STALLS, it is usually because it is being overloaded. RELEASE TRIGGER IMME-
DIATELY, remove drill bit from work, and determine cause of stalling. DO NOT CLICK TRIG-
GER OFF AND ON IN AN ATTEMPT TO START A STALLED DRILL – THIS CAN DAMAGE
THE DRILL.
8. Keep the motor running when pulling the bit back out of a drilled hole. This will help prevent
jamming.
Operation as a Screwdriver
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. Make a few prac-
tice runs in scrap or unseen areas to determine the proper position of the clutch collar.
MAINTENANCE
Cleaning
CAUTION: With the motor running, blow dirt and dust out of all air vents with dry air at least
once a week. Wear safety glasses when performing this. Exterior plastic parts may be cleaned
with a damp cloth and mild detergent. Although these parts are highly solvent resistant, NEVER
use solvents.
CHARGER CLEANING INSTRUCTIONS
WARNING: Shock hazard. Disconnect the charger from the AC outlet before cleaning. Dirt
and grease may be removed from the exterior of the charger using a cloth or soft non-metallic
brush. Do not use water or any cleaning solutions.
