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 create 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. Acharger 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 under the influence of drugs, alcohol, or med-
ication. A moment of inattention while operating power tools may result in serious personal injury,
• Dress properly. Do not wear loose clothing or jewelry. Contain long hair. Keep
your hair, clothing, and gloves away from moving parts. Loose clothing, jewelry, or long
hair can be caught in moving parts. Air vents cover moving parts, and should be avoided as well.
• Avoid accidental starting. Be sure switch is in the locked or off position before
inserting battery pack. Carrying tools with your finger on the switch or inserting the
battery pack into a tool with the switch on invites accidents.
• Remove adjusting keys or wrenches before turning the tool on. A wrench or a key
that is left attached to a rotating part of the tool may result in personal injury.
• Do not overreach. Keep proper footing and balance at all times. Proper footing and
balance enables better control of the tool in unexpected situations.
• Use safety equipment. Always wear eye protection. Dust mask, non-skid safety
shoes, hard hat, or hearing protection must be used for appropriate conditions.
TOOL USE AND CARE
• Use clamps or other practical way to secure and support the workpiece to a
stable platform. Holding the work by hand or against your body is unstable and may
lead to a loss of control.
• Do not force tool. Use the correct tool for your application. The correct tool will do the
job better and safer at the rate for which it is designed.
• Do not use tool if switch does not turn it on or off. A tool that cannot be controlled
with the switch is dangerous and must be repaired.
• Disconnect battery pack from tool or place the switch in the locked or off posi-
tion before making any adjustments, changing 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 manufacturer 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 personnel 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.
Additional 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.
CAUTION: Some tools with large battery packs will stand upright on the battery pack
but may be easily knocked over. When not in use, place tool on its side on a stable surface where it will not cause a tripping or falling hazard.
CAUTION: Wear appropriate hearing protection during use. Under some condi-
tions and duration of use, noise from this product may contribute to hearing loss.
WARNING: Some dust created by power sanding, sawing, grinding, 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 (CCA).
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, sawing, 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.
• The label on your tool may include the following symbols.
V ............volts A ................amperes
Hz ..........hertz W................watts
min..........minutes ..............alternating current
........direct current

Important Safety Instructions for Battery Packs
The battery pack is not fully charged out of the carton! First read the safety instructions
below. Then follow charging notes and procedures.
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.
• 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
E
WALT chargers.
• NOTE: The batteries in your battery pack are the nickel–cadmium type. Cadmium is
considered to be a toxic material by the Environmental Protection Agency. Before disposing of damaged or worn out Nickel–Cadmium battery packs, check with your state
Environmental Protection Agency to find out about special restrictions on the disposal
of these battery packs or return them to a D
E
WALT certified service center for recycling.
• 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. Danger of electric shock or electrocution. 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 con-
tact exposed battery terminals.
For example, do not place battery in aprons,
pockets, tool boxes, product kit boxes, drawers, etc. with loose nails, screws, keys, etc. without battery cap. Without cap in place, battery could short circuit causing fire or burns or
damage to battery.
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 retailer 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
D
E
WALT battery chargers.
• Before using battery charger, read all instructions and cautionary markings on battery
charger, battery and product using battery.
CAUTION:To reduce the risk of injury, charge only DEWALT nickel cadmium recharge-
able 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.
DANGER: 120 volts present at charging terminals. Do not probe with conductive
objects. Danger of electric shock or electrocution.
WARNING: Don’t allow any liquid to get inside charger. Electric shock may result.
• The charger and battery pack are specifically designed to work together. DO NOT
attempt to charge the battery pack with any chargers other than the ones in this
manual.
• These chargers are not intended for any uses other than charging D
E
WALTrechargeable
batteries. Any other uses may result in risk of fire, electric shock or electrocution.
• To reduce risk of damage to electric plug and cord, pull by plug rather than cord when
disconnecting charger.
• Make sure cord is located so that it will not be stepped on, tripped over, or otherwise
subjected to damage or stress.
• An extension cord should not be used unless 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.
Recommended Minimum AWG Size for Extension Cords

Charging Procedure
1 HOUR CHARGERS
1. Plug the charger into an appropriate power outlet.
2. Insert the battery pack into the charger, as shown in FIG.1, making sure the pack is
fully seated in the charger. The red (charging) light will blink continuously indicating that
the charging process has started.
3. The battery pack will be fully charged in about 1 hour. 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.
TROUBLE INDICATORS: These chargers are designed to detect certain problems that
can arise with battery packs which would be indicated by the red light flashing at a fast rate
(and continuous beeping for 15 Minute Chargers). If this occurs, re-insert battery pack. If
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 for recycling. If the new battery pack elicits the same trouble indication as the
original, have charger tested at an authorized service center.
PROBLEM POWER LINE
If your charger has 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.
HOT PACK DELAY
If your charger has a Hot 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.
15 MINUTE CHARGERS
1. Plug the charger into an appropriate power outlet. The charger will beep twice, the red
light will blink and go off.
2. Insert the battery pack into the charger, as shown in FIG. 1, making sure the pack is
fully seated in the charger. The red light will blink and the charger will beep once indicating the charging process has started.
3. The battery pack will be fully charged in less than 15 minutes under most conditions.
This will be indicated by the red light remaining ON and 3 beeps. The pack is fully
charged and may be used at this time or left in the charger.
WEAK BATTERY PACKS: The charger 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.
15 MINUTE CHARGER
FIG. 1
1 HOUR CHARGER
ALL CHARGERS
Leaving the battery pack in the charger: When the red light remains ON, the charger
has switched to its "equalize charge" mode which lasts approximately 4 hours, after which
the charger will switch to "maintenance charge" mode. The battery pack can be removed
at any time during these charge cycles, but will only be fully charged if the red light is continuously ON. 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. 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. Abattery pack
may also slowly lose its charge if left in a charger that is not plugged into an appropriate
AC source.
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 — (1) Check current at receptacle by plugging in a lamp or other appliance, (2) Check to see if receptacle is connected to a light
switch which turns power off when you turn out the lights. (3) Move charger and battery pack to a location where the surrounding air temperature is approximately 65°F 75°F (18°- 24°C). (4) If charging problems persist, take or send 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. Do not 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 hous-
ing of the battery pack breaks or cracks, return to a service center for recycling.
OPERATION
Installing and Removing the Battery Pack (Fig. 2, 3)
NOTE: Make sure your battery pack is fully charged.
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 as shown. To remove the battery pack from the tool, press the release
buttons 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
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.
The variable speed switch enables you to select the best speed for a particular application.
The farther you squeeze the trigger, 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 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. 4) 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 forward/reverse control button on the left side of the tool. 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.
Torque Adjustment Collar
The torque adjustment collar is clearly marked with numbers and a drill bit symbol.The collar should be rotated until the desired setting is located at the top of the tool, (FIG. 5).
Locators are provided in the collar to eliminate the guess work when selecting fastening
torque. The higher the number on the collar, the higher the torque and the larger the fastener which can be driven. 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 arrow on the top of the tool. Failure
to do this will allow the clutch to slip while attempting to drill
Dual Range Gearing
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) (position 1), as shown in FIG. 5. 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 Chuck
Your tool features a 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,
as shown in FIG 6. 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.
Single Sleeve Chuck
Some tools feature a keyless chuck with one plastic sleeve for one-handed operation of
the chuck. To insert a drill bit or other accessory, follow the steps listed below.
1. Lock the trigger in the off position (Fig. 4).
2. Grasp the black sleeve of the chuck with one hand and rotate the sleeve counterclockwise until it is open enough to accept the desired tool.
3. Insert the tool shank about 3/4" (18 mm) and tighten the chuck by rotating the sleeve
clockwise.
WARNING: Do not attempt to tighten drill bits (or 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 the trigger in the off position when changing accessories.
Be sure to tighten the chuck with one hand on the chuck sleeve and one hand firmly holding the drill for maximum tightness.
NOTE: Do not install a single sleeve chuck onto a tool that has a standard two sleeve, keyless chuck. Tools originally built with a single-sleeve chuck have an internal locking mechanism that is not part of the chuck. Therefore the single-sleeve chuck will not function properly on tools originally built with standard two-sleeve chucks.
Chuck Removal
Always wear eye protection.
Turn the adjustment collar to the “drill” position and low speed gear shifter position 1.
Tighten the chuck around the shorter end of a hex key (not supplied) 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. 7. This will loosen the screw inside the chuck.
FIG. 6
English
5
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-handthread). Place hex key in chuck and tighten, as shown in FIG. 8. 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. 7. Tighten the screw once again by turning in a counterclockwise direction.
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 dual range 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 or 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.
Operation as a Hammerdrill
To utilize the hammer feature of your tool, rotate the collar to align the hammer symbol
with the arrow shown in FIG.5. 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.
FIG. 8
FIG. 7
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.
Drilling in Wood
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.
Drilling in Metals
Use a cutting lubricant when drilling metals. The exceptions are cast iron and brass which
should be drilled dry. The cutting lubricants that work best are sulphurized cutting oil or lard
oil; bacon grease will also serve the purpose.
Drilling Masonry
Use carbide tipped masonry bits at low speeds. Keep even force on the drill but not so
much that you crack the brittle materials. A smooth, even flow of dust indicates the proper
drilling rate.
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 practice runs in scrap or unseen areas to determine the proper position of the clutch
collar.
Maintenance
CLEANING: 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 nonmetallic brush. Do not use water or any cleaning solutions.
