General Safety Rules – For All Battery
Operated Tools
WARNING! Read and understand all instructions. Failure
to follow all instructions listed below may result in electric
shock, fire and/or serious personal injury.
SAVE THESE INSTRUCTIONS
WORK AREA
• Keep your work area clean and well lit. Cluttered benches and
dark areas invite accidents.
• Do not operate power tools in explosive atmospheres, such
as in the presence of flammable liquids, gases, or dust. Power
tools create sparks which may ignite the dust or fumes.
• Keep bystanders, children, and visitors away while operating
a power tool. Distractions can cause you to lose control.
ELECTRICAL SAFETY
• Do not abuse the cord. Never use the cord to carry the tool.
Keep cord away from heat, oil, sharp edges or moving parts.
Replace damaged cords immediately. Damaged cords may cre-
ate a fire.
• A battery operated tool with integral batteries or a separate
battery pack must be recharged only with the specified charger for the battery. A charger that may be suitable for one type of
battery may create a risk of fire when used with another battery.
• Use battery operated tool only with the specifically designated
battery pack. Use of any other batteries may create a risk of fire.
PERSONAL SAFETY
• Stay alert, watch what you are doing and use common sense
when operating a power tool. Do not use tool while tired or
ing accessories, or storing the tool. Such preventative safety
measures reduce the risk of starting the tool accidentally.
• Store idle tools out of reach of children and other untrained
persons. Tools are dangerous in the hands of untrained users.
• When battery pack is not in use, keep it away from other metal
objects like: paper clips, coins, keys, nails, screws, or other
small metal objects that can make a connection from one terminal to another. Shorting the battery terminals together may
cause sparks, burns, or a fire.
• Maintain tools with care. Keep cutting tools sharp and clean.
Properly maintained tools, with sharp cutting edges are less likely
to bind and are easier to control.
• Check for misalignment or binding of moving parts, breakage
of parts, and any other condition that may affect the tools
operation. If damaged, have the tool serviced before using.
Many accidents are caused by poorly maintained tools.
• Use only accessories that are recommended by the manufac-
turer for your model. Accessories that may be suitable for one
tool, may create a risk of injury when used on another tool.
SERVICE
• Tool service must be performed only by qualified repair personnel. Service or maintenance performed by unqualified person-
nel may result in a risk of injury.
• When servicing a tool, use only identical replacement parts.
Follow instructions in the Maintenance section of this manual. Use of unauthorized parts or failure to follow Maintenance
Instructions may create a risk of shock or injury.
Specific Safety Rules
• Hold tool by insulated gripping surfaces when performing an
operation where the tool may contact hidden wiring. Contact
with a “live” wire will also make exposed metal parts of the tool
“live” and shock the operator.
• Wear ear protectors when hammering for extented periods of
time. Prolonged exposure to high intensity noise can cause hear-
1
English
ing loss. Temporary hearing loss or serious ear drum damage may
result from high sound levels generated by hammer drilling.
• Wear safety goggles or other eye protection. Hammering and
drilling operations cause chips to fly. Flying particles can cause permanent eye damage.
• Always use the side handle supplied with the tool. Keep a firm
grip on the tool at all times. Do not attempt to operate this tool without holding it with both hands.
• Hammer bits and tools get hot during operation. Wear gloves
when touching them.
WARNING: Some dust created by power sanding, sawing, grind-
ing, drilling, and other construction activities contains chemicals
known to cause cancer, birth defects or other reproductive harm.
Some examples of these chemicals are:
• lead from lead-based paints,
• crystalline silica from bricks and cement and other masonry
products, and
• arsenic and chromium from chemically-treated lumber.
Your risk from these exposures varies, depending on how often you
do this type of work. To reduce your exposure to these chemicals:
work in a well ventilated area, and work with approved safety equipment, such as those dust masks that are specially designed to filter
out microscopic particles.
• Avoid prolonged contact with dust from power sanding, saw-
ing, grinding, drilling, and other construction activities. Wear
protective clothing and wash exposed areas with soap and
water. Allowing dust to get into your mouth, eyes, or lay on the skin
may promote absorption of harmful chemicals.
WARNING: Use of this tool can generate and/or disburse dust,
which may cause serious and permanent respiratory or other injury.
Always use NIOSH/OSHA approved respiratory protection appropriate for the dust exposure. Direct particles away from face and body.
CAUTION: When not in use, place tool on its side on a stable
surface where it will not cause a tripping or falling hazard. Some
2
tools with large battery packs will stand upright on the battery pack but
may be easily knocked over.
CAUTION: DO NOT TOUCH ANY METAL PARTS OF THE TOOL
when drilling or driving into walls, floors or wherever live electrical
wires may be encountered! Hold the tool only by insulated grasping
surfaces to prevent electric shock if you drill or drive into a live wire.

Important Safety Instructions
for Battery Packs
Your tool uses either a 12, 14.4 or 18 Volt DEWALT battery pack. When
ordering replacement battery packs, be sure to include catalog number and voltage: Extended Run-Time battery packs deliver 25% more
run-time than standard battery packs.
NOTE: Your tool will accept either standard or Extended Run Time
battery packs. However, be sure to select proper voltage.
The battery pack is not fully charged out of the carton. Before using
the battery pack and charger, read the safety instructions below. Then
follow charging procedures outlined.
READ ALL INSTRUCTIONS
• Do not incinerate the battery pack even if it is severely damaged or is completely worn out. The battery pack can explode in
a fire.
English
• A small leakage of liquid from the battery pack cells may
occur under extreme usage or temperature conditions. This
does not indicate a failure. However, if the outer seal is broken and
this leakage gets on your skin:
a. Wash quickly with soap and water.
b. Neutralize with a mild acid such as lemon juice or vinegar.
c. If battery liquid gets into your eyes, flush them with clean water
for a minimum of 10 minutes and seek immediate medical
attention. (Medical note: The liquid is 25-35% solution of potassium hydroxide.)
• Do not carry extra battery packs in aprons, pockets, or tool
boxes along with other metal objects. Battery pack could be
short circuited causing damage to the battery pack and possibly
causing severe burns or fire.
• Charge the battery packs only in D
EWALT chargers.
• DO NOT splash or immerse in water or other liquids.
• Do not store or use the tool and battery pack in locations
where the temperature may reach or exceed 105°F (such as
outside sheds or metal buildings in summer).
DANGER: Never attempt to open the battery pack for any reason.
If battery pack case is cracked or damaged, do not insert into charger. Electric shock or electrocution may result. Damaged battery packs
should be returned to service center for recycling.
NOTE: Battery storage and carrying caps are provided
for use whenever the battery is out of the tool or charger.
Remove cap before placing battery in charger or tool.
WARNING: Do not store or carry battery so that
metal objects can contact exposed battery terminals.
For example, do not place battery in aprons, pockets,
tool boxes, product kit boxes, drawers, etc. with loose nails,

The RBRC™ Seal
The RBRC™ (Rechargeable Battery Recycling Corporation) Seal on the nickel-cadmium battery (or battery pack)
indicates that the costs to recycle the battery (or battery
pack) at the end of its useful life have already been paid by
D
EWALT. In some areas, it is illegal to place spent nickel-
cadmium batteries in the trash or municipal solid waste stream and the
RBRC program provides an environmentally conscious alternative.
RBRC in cooperation with D
EWALT and other battery users, has
established programs in the United States to facilitate the collection of
spent nickel-cadmium batteries. Help protect our environment and
conserve natural resources by returning the spent nickel-cadmium
battery to an authorized D
EWALT service center or to your local retail-
er for recycling. You may also contact your local recycling center for
information on where to drop off the spent battery.
Important Safety Instructions for Battery
Chargers
SAVE THESE INSTRUCTIONS: This manual contains important
safety instructions for battery chargers.
• Before using charger, read all instructions and cautionary markings
on charger, battery pack, and product using battery pack.
DANGER: 120 volts are present at charging terminals. Do not probe
with conductive objects. Electric shock or electrocution may result.
WARNING: Do not allow any liquid to get inside charger. Electric
shock may result.
CAUTION: To reduce the risk of injury, charge only D
EWALT nickel
cadmium rechargeable batteries. Other types of batteries may burst
causing personal injury and damage.
CAUTION: Under certain conditions, with the charger plugged in to
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.
•
DO NOT attempt to charge the battery pack with any chargers
other than the ones in this manual. The charger and battery
pack are specifically designed to work together.
• These chargers are not intended for any uses other than
charging D
EWALT rechargeable batteries. Any other uses may
result in risk of fire, electric shock or electrocution.
• Do not expose charger to rain or snow.
• Pull by plug rather than cord when disconnecting charger.
This will reduce risk of damage to electric plug and cord.
• 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.
• 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. When using more than one
extension to make up the total length, be sure each individual
extension contains at least the minimum wire size.

• 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.
Battery Performance
Some chargers have a Tune-Up™ feature that optimizes battery pack
performance. Your charger may provide automatic Tune-Up™ mode
or manual (i.e., push button) Tune-Up™ mode. For information on this
feature, please see the appropriate section below. Because batteries
slowly lose their charge when they are not on the charger, the best
place to keep your battery pack is on the charger at all times.
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. Whenever 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 Tune-Up™ Mode.
4. Once the automatic Tune-Up™ Mode is complete the charger will
transition to a maintenance charge; the indicator light shuts off
when the automatic Tune-Up™ Mode is complete.
USING THE MANUAL TUNE-UP™ MODE
The manual Tune-Up™ mode equalizes or balances the individual
cells in the battery pack allowing it to function at peak capacity. This
mode takes up to 8 hours to complete. 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.
1. To tune up your battery pack, place the battery in the charger as
usual. The red light will blink continuously indicating that the
charge cycle has started.
2. Press the Tune-Up™ Mode button any time after the charge cycle
has started. The red light will stop blinking momentarily, blink
quickly 3 times, and then resume blinking continuously. The
charger is now tuning up the cells in your battery.
3. When the Tune-Up™ mode cycle is complete, the light will stay on
continuously. The pack is fully charged and may be used at this
time or left in the charger.
4. If you select Tune-Up™ Mode and then change your mind,
remove the battery from the charger. After 5 seconds, insert the
battery into the charger. The normal charge cycle will begin.

Chargers
Your tool uses a 12.0, 14.4,18.0 Volt DEWALT Charger. Your battery
can be charged in D
EWALT 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
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.
CAUTION: 120 volts present at charging terminals. Do not probe
with conductive objects. Danger of electric shock or electrocution.
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.
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
condition. 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.
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: Don't allow any liquid to get inside charger. Electric
shock may result. 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.
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.

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.
Side Handle
CAUTION: Always hold drill with both hands
and use side handle if so equipped. Side handle
clamps to the front of the gear case as shown and
can be rotated 360˚ to permit right- or
left-hand use. Be sure side handle is installed
tightly. If model is not equipped with side handle,
grip drill with one hand on the handle and one
hand on the battery pack.
NOTE: Side handle comes equipped on models DC987, DC988,
DC989.
Operation as a Drill
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 results when drilling.
DRILLING
1. Use sharp drill bits only. For WOOD, use twist drill bits, spade bits,
power auger bits, or hole saws. For METAL, use high speed steel
twist drill bits or hole saws. For MASONRY, such as brick, cement,
cinder block, etc., use carbide-tipped bits.
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 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.
6. To minimize stalling as you are breaking through the material,
reduce pressure on drill 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.
Drilling in Wood
Start drilling with slow speed and increase to full power while applying firm pressure to 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. For larger holes,
use low speed wood bits. Work that is likely to splinter should be
backed up with a block of wood.

FIG. 4
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" to 1/2") holes in steel can be made easier if a pilot
hole (5/32" to 3/16") is drilled first.
Drilling in Masonry
(TOOLS WITHOUT A HAMMER FEATURE)
Use carbide tipped bits rated for percussion drilling and be certain
that the bit is sharp. Use a constant and firm force on the tool to drill
most effectively. A smooth, even flow of dust indicates the proper
drilling rate.
Operation as a Hammerdrill
Some models have the Hammerdrill feature. To utilize the hammer
feature of your tool, rotate the collar to align the hammer symbol with
the arrow shown in Figure 3. The hammering position is for hammer
drilling in soft concrete and masonry such as brick, mortar and soft
ceramics.
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. Do not pour water into the hole to settle dust. Water causes clogging of bit flutes which will tend to make the bit bind in the hole.

Operation as a Screwdriver
Select the desired speed/torque range using the 3 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). Make a
few practice 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: 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.
Repairs
To assure product SAFETY and RELIABILITY, repairs, maintenance
and adjustment (including brush inspection and replacement) should
be performed by certified service centers or other qualified service
organizations, always using identical replacement parts.
