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 acci-
dents.
• 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
• 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 suit-
able for one type of battery may create a risk of fire when used with another battery.
• Use battery operated tool only with the specifically designed 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 medica-
tion. 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.
• Avoid accidental starting. Be sure switch is in the locked off position before inserting bat-
tery 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 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 bal-
ance 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 and the rate for which it is designed.
• Do not use tool if switch does not turn it on or off. Any 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 position
before making any adjustments, changing accessories, or storing the tool. Such pre-
ventative safety measures reduce the risk of starting the tool accidentally.
• Store idle tools out of reach of children and other untrained persons. Tools are dan-
gerous 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 con-
nection 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 become hazardous when used on anoth-
er tool.
SERVICE
• Tool service must be performed only by qualified repair personnel. Service or mainte-
nance performed by unqualified personnel could 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 electric shock or injury.
Additional Specific Safety Rules for Rotary Hammers
• Hold tool by insulated gripping surfaces when performing an operation where the
cutting tool may contact hidden wiring or its own cord. Contact with a “live” wire will
make exposed metal parts of the tool “live” and shock the operator.
• Wear ear protectors when hammering for extented periods of time. Temporary hear-
ing loss or serious ear drum damage may result from high sound levels generated by ham-
mer 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.
• 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.
WARNING: Use of this tool can generate dust containing chemicals known to cause can-
cer, birth defects or other reproductive harm. Use appropriate respiratory protection.

Additional Specific Safety Instructions When Using
DW0247 AC Adapter (Fig. 4)
• Double insulated tools are equipped with a polarized plug (one blade is wider than the
other.) This plug will fit in a polarized outlet only one way. If the plug does not fit fully in the
outlet, reverse the plug. If it still does not fit, contact a qualified electrician to install a polar-
ized outlet. Do not change the plug in any way. Double insulation eliminates the need for
the three wire grounded power cord and grounded power supply system. Applicable only to
Class II (double insulated) tools.
• Avoid body contact with grounded surfaces such as pipes, radiators, ranges and refrigera-
tors. There is an increased risk of electric shock if your body is grounded.
• Don’t expose power tools to rain or wet conditions. Water entering a power tool will increase
the risk of electric shock.
• Do not abuse the cord. Never use the cord to carry the tools or pull the plug from an outlet.
Keep cord away from heat, oil, sharp edges or moving parts. Replace damaged cords
immediately. Damaged cords increase the risk of electric shock.
• When operating a power tool outside, use an outdoor extension cord marked “W-A” or “W.”
These cords are rated for outdoor use and reduce the risk of electric shock.

• Avoid accidental starting. Be sure switch is off before plugging in. Carrying tools with your
finger on the switch or plugging in tools that have the switch on invites accidents.
• Disconnect the plug from the power source before making any adjustments, changing
accessories, or storing the tool. Such preventative safety measures reduce the risk of start-
ing the tool accidentally.

FOR FUTURE USE
Battery Packs
Your tool uses a 24.0 Volt D
EWALT battery pack. When ordering replacement battery packs,
be sure to include catalog number and voltage.
CAUTION: 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
EWALT certified service center for recycling.
HOT PACK /COLD PACK DELAY
If your charger has a Hot Pack Delay feature, when it detects a battery that is hot or excessively
cold, it automatically starts a Hot Pack /Cold Pack Delay, suspending charging until the battery
has stabilized. The charger will automatically switch 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.
Using Tune-Up™ Mode
The Tune-up™ mode will equalize or balance the individual cells in the battery pack at its peak
capacity. This cycle takes up to 8 hours to complete. Battery packs should be tuned up weekly
or after 10 to 20 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. The Tune-up™ Button may be pressed at any time after the charge has started. The red light
will stop blinking momentarily, blink quickly 3 times, and then resume blinking continuously.
The charger is now giving your batteries a tune-up.
3. When the charge cycle has completed, 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™ 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 commence.
Installing and Removing the Battery Pack (Fig. 1)
NOTE: Make sure your battery pack is fully charged. To install the battery pack into the tool,
set the lock off button to disable the trigger switch, align the front of the battery with the notch-
es inside the tool’s body and slide the battery pack firmly into place until you hear the lock
snap into place.
To remove the battery pack from the tool, depress release buttons (B) on both sides,
remove the battery pack (C). Insert it into the charger as described in the charger manual.
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
