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 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 before
E
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 °C–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 °C–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.

OPERATION
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.
Installing and Removing the Battery Pack (Fig. 2)
NOTE: 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 2.
To remove the battery pack from the tool, press the release buttons (F) 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.
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.
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. Turn the collar to the drill bit symbol for drilling or to the hammer symbol for hammerdrilling.
2. Select the desired speed/torque range using the gear shifter to match the speed and torque to
the planned operation.
3. 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. For MASONRY, use carbide-
tipped bits or masonry bits. A smooth, even flow of dust indicates the proper drilling rate.
4. 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.
5. Hold tool firmly with both hands to control the twisting action of the drill.
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.
6. 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 CLICK
TRIGGER OFF AND ON IN AN ATTEMPT TO START A STALLED DRILL – THIS CAN
DAMAGE THE DRILL.
7. Keep the motor running when pulling the bit back out of a drilled hole. This will help prevent
jamming.
8. To minimize stalling or breaking through the material, reduce pressure on drill and ease the bit
through the last fractional part of the hole.
9. 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.
HAMMERDRILL OPERATION
1. When drilling, use just enough force on the hammer to keep it from bouncing excessively or
"rising" off the bit. Too much force will cause slower drilling speeds, overheating, and a lower
drilling rate.
2. 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.
3. 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.
4. For masonry, use carbide-tipped bits or masonry bits. A smooth even flow of dust indicates the
proper drilling rate.
SCREWDRIVER OPERATION
Select the desired speed/torque range using the three-speed gear shift lever 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. Set the torque adjustment collar (Fig. 3) to the desired setting.
Make a few practice runs in scrap or unseen areas to determine the proper position of the clutch
collar.
MAINTENANCE
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
E
or accessories.
Cleaning
WARNING: Blow dirt and dust out of all air vents with clean, dry air at least once a week.
