• Make sure that cord is located so that it will not be stepped on, tripped over, or
otherwise subjected to damage or stress.
• Do not use an extension cord unless it is absolutely necessary. Use of improper
extension cord could result in risk of fire, electric shock, or electrocution.
• When operating a power tool outdoors, use an extension cord suitable for outdoor
use. Use of a cord suitable for outdoor use reduces the risk of electric shock.
• An extension cord must have adequate wire size (AWG or American Wire Gauge)
for safety. The smaller the gauge number of the wire, the greater the capacity of the cable,
that is 16 gauge has more capacity than 18 gauge. An undersized cord will cause a drop in
line voltage resulting in loss of power and overheating. When using more than one extension
to make up the total length, be sure each individual extension contains at least the minimum
wire size. The following table shows the correct size to use depending on cord length and
nameplate ampere rating. If in doubt, use the next heavier gauge. The smaller the gauge
number, the heavier the cord.

• 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 two chargers together.
• The charger is designed to operate on standard 120 volt 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 charger. Be sure to read all safety instructions before using your
E
charger. Consult the chart at the end of this manual for compatibility of chargers and battery
packs.
Charging Procedure (Fig. 1)
DANGER: Electrocution hazard. 120 volts are present at charging terminals. Do not probe
with conductive objects. Electric shock or electrocution may result.
1. Plug the charger into an appropriate outlet before inserting battery pack.
2. Insert the battery pack (E) into the charger, as shown in Figure 1, making sure the pack
is fully seated in 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 operation of 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.
WARNING: Burn hazard. 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. For long storage, it is recommended to store a fully charged battery pack in a cool dry place
out of the charger for optimal results.
NOTE: Battery packs should not be stored completely depleted of charge. The battery pack will
need to be recharged before use..

OPERATION
WARNING: To reduce the risk of injury, turn unit off and disconnect it from power
source before installing and removing accessories, before adjusting or when making
repairs. An accidental start-up can cause injury.
Installing and Removing the Battery Pack (Fig. 4)
NOTE: For best results, make sure your battery pack is fully charged.
To install the battery pack into the tool handle, align the notch inside the tool's handle with the
battery pack and slide the battery pack firmly into the handle until you hear the lock snap into
place as shown in Figure 4.
To remove the battery pack from the tool, press the release buttons (D) 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.
Variable Speed Switch (Fig. 2)
To turn the tool on, squeeze the trigger switch (A). 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.
The variable speed switch enables you to start the application at a slow speed. The farther you
squeeze the trigger, the faster the tool will operate. For maximum tool life, use variable 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.
Forward/Reverse Control Button (Fig. 2)
A forward/reverse control button (B) determines the direction the chuck will spin and also serves
as a lock off button. The center position of the control button 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.
Two Position Screwdriver (Fig. 2)
To convert the tool to an angled screwdriver pull back on the release button (C) and rotate the
top portion of the tool as shown.
TWO POSITION SCREWDRIVER WARNINGS:
• To avoid being pinched, hold the screwdriver and keep hands away from the hinge when
changing positions.
• Do not use screwdriver as a pry bar in either position.
• To avoid screwdriver being turned on accidentally, put the Forward/Reverse switch in the
center, locked-off, position.
Torque Adjustment Collar (Fig. 3)
The torque adjustment collar (G) is marked with numbers and a drill bit symbol. The higher the
number on the collar, the higher the torque. To lock the clutch for drilling operations, move to the
drill bit position. Failure to do this will allow the clutch to slip while attempting to drill.
Quick Release Chuck (Fig. 3)
Note: The chuck accepts 1/4" (6.4 mm) hex accessories only.
To install a bit, insert the bit into the chuck until the clip locks it in place.
To remove a bit, pull the chuck (F) back. Remove the bit and release the chuck.
Operation as a Drill
Turn the collar to the drill bit symbol. Install the hex shank drill bit in the chuck. Follow these
instructions for best results when drilling.
DRILLING
1. Use D
WALT hex shank drill bits only.
E
2. Be sure the material to be drilled is anchored or clamped firmly. If drilling thin material, use a
"back-up" block to prevent damage to the material.
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 to control the twisting action of the drill.
5. IF TOOL STALLS, it is usually because it is being overloaded. RELEASE TRIGGER
IMMEDIATELY, remove drill bit from work, and determine cause of stalling. DO NOT CLICK
TRIGGER OFF AND ON IN AN ATTEMPT TO START A STALLED TOOL – THIS CAN
DAMAGE THE TOOL.
6. To minimize stalling or breaking through the material, reduce pressure on tool and ease the
bit through the last fractional part of the hole.
7. Keep the motor running when pulling the bit back out of a drilled hole. This will help prevent
jamming.
8. 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. Operate at full on after starting the bit.
Operation as a Screwdriver
Insert the appropriate hex shank bit into the chuck. Make a few practice runs in scrap or unseen
areas to determine the proper position of the torque adjustment collar.
MAINTENANCE
WARNING: To reduce the risk of injury, turn unit off and disconnect it from power
