General Power Tool Safety Warnings
WARNING! Read all safety warnings and all instructions.
Failure to follow the warnings and instructions may result in
electric shock, fire and/or serious injury.
SAVE ALL WARNINGS AND INSTRUCTIONS
FOR FUTURE REFERENCE
The term “power tool” in the warnings refers to your mains-operated
(corded) power tool or battery-operated (cordless) power tool.
1) WORK AREA SAFETY
a) Keep work area clean and well lit. Cluttered or dark areas
invite accidents.
b) 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.
c) Keep children and bystanders away while operating a
power tool. Distractions can cause you to lose control.
2) ELECTRICAL SAFETY
a) Power tool plugs must match the outlet. Never modify
the plug in any way. Do not use any adapter plugs with
earthed (grounded) power tools. Unmodified plugs and
matching outlets will reduce risk of electric shock.
b) Avoid body contact with earthed or grounded surfaces
such as pipes, radiators, ranges and refrigerators. There
is an increased risk of electric shock if your body is earthed or
grounded.
c) Do not expose power tools to rain or wet conditions.
Water entering a power tool will increase the risk of electric
shock.
d) Do not abuse the cord. Never use the cord for carrying,
pulling or unplugging the power tool. Keep cord away
from heat, oil, sharp edges or moving parts. Damaged or
entangled cords increase the risk of electric shock.
e) 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.
f) If operating a power tool in a damp location is unavoidable,
use a ground fault circuit interrupter (GFCI) protected
supply. Use of a GFCI reduces the risk of electric shock.

3) PERSONAL SAFETY
a) Stay alert, watch what you are doing and use common
sense when operating a power tool. Do not use a power
tool while you are tired or under the influence of drugs,
alcohol or medication. A moment of inattention while
operating power tools may result in serious personal injury.
b) Use personal protective equipment. Always wear eye
protection. Protective equipment such as dust mask, non-
skid safety shoes, hard hat, or hearing protection used for
appropriate conditions will reduce personal injuries.
c) Prevent unintentional starting. Ensure the switch is in
the off position before connecting to power source and/
or battery pack, picking up or carrying the tool. Carrying
power tools with your finger on the switch or energizing power
tools that have the switch on invites accidents.
d) Remove any adjusting key or wrench before turning the
power tool on. A wrench or a key left attached to a rotating
part of the power tool may result in personal injury.
e) Do not overreach. Keep proper footing and balance at
all times. This enables better control of the power tool in
unexpected situations.
f) Dress properly. Do not wear loose clothing or jewelry.
Keep your hair, clothing and gloves away from moving
parts. Loose clothes, jewelry or long hair can be caught in
moving parts.
g) If devices are provided for the connection of dust
extraction and collection facilities, ensure these are
connected and properly used. Use of dust collection can
reduce dust-related hazards.
4) POWER TOOL USE AND CARE
a) Do not force the power tool. Use the correct power tool
for your application. The correct power tool will do the job
better and safer at the rate for which it was designed.
b) Do not use the power tool if the switch does not turn it
on and off. Any power tool that cannot be controlled with the
switch is dangerous and must be repaired.
c) Disconnect the plug from the power source and/or the
battery pack from the power tool before making any
adjustments, changing accessories, or storing power
tools. Such preventive safety measures reduce the risk of
starting the power tool accidentally.
d) Store idle power tools out of the reach of children and
do not allow persons unfamiliar with the power tool or
these instructions to operate the power tool. Power tools
are dangerous in the hands of untrained users.
e) Maintain power tools. Check for misalignment or binding
of moving parts, breakage of parts and any other
condition that may affect the power tool’s operation. If
damaged, have the power tool repaired before use. Many
accidents are caused by poorly maintained power tools.
f) Keep cutting tools sharp and clean. Properly maintained
cutting tools with sharp cutting edges are less likely to bind and
are easier to control.
g) Use the power tool, accessories and tool bits, etc. in
accordance with these instructions, taking into account
the working conditions and the work to be performed.
Use of the power tool for operations different from those
intended could result in a hazardous situation.
5) BATTERY TOOL USE AND CARE
a) Recharge only with the charger specified by the
manufacturer. A charger that is suitable for one type of
battery pack may create a risk of fire when used with another
battery pack.
b) Use power tools only with specifically designated battery
packs. Use of any other battery packs may create a risk of
injury and fire.
English

c) 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 burns or a fire.
d) Under abusive conditions, liquid may be ejected from
the battery; avoid contact. If contact accidentally occurs,
flush with water. If liquid contacts eyes, additionally seek
medical help. Liquid ejected from the battery may cause
irritation or burns.
6) SERVICE
a) Have your power tool serviced by a qualified repair
person using only identical replacement parts. This will
ensure that the safety of the power tool is maintained.
Drill/Driver/Hammerdrill Safety Warnings
• Wear ear protectors when impact drilling. Exposure to noise
can cause hearing loss.
• Use auxiliary handle(s), if supplied with the tool. Loss of
control can cause personal injury.
•Hold power tool by insulated gripping surfaces, when
performing an operation where the cutting accessory may
contact hidden wiring. Cutting accessory contacting a “live”
wire may make exposed metal parts of the power tool “live” and
could give the operator an electric shock.
•Use clamps or another practical way to secure and support
the workpiece to a stable platform. Holding the work by hand
or against your body leaves it unstable and may lead to loss of
control.
•Wear ear protectors when hammering for extented periods
of time. Prolonged exposure to high intensity noise can cause
hearing 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.Wear a dust mask or respirator for
applications that generate dust. Ear protection may be required for
most applications.
•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. Operating this
tool with one hand will result in loss of control. Breaking through or
encountering hard materials such as re-bar may be hazardous as
well.
•Accessories and tool may get hot during operation. Wear
gloves when handling them if performing heat producing
applications such as hammerdrilling and drilling metals.
• Do not operate this tool for long periods of time. Vibration
caused by hammer action may be harmful to your hands and
arms. Use gloves to provide extra cushion and limit exposure by
taking frequent rest periods.
•Air vents often cover moving parts and should be avoided.
Loose clothes, jewelry or long hair can be caught in moving parts.
WARNING: ALWAYS use safety glasses. Everyday eyeglasses are
NOT safety glasses. Also use face or dust mask if cutting operation is
dusty. ALWAYS WEAR CERTIFIED SAFETY EQUIPMENT:
• ANSI Z87.1 eye protection (CAN/CSA Z94.3),
• ANSI S12.6 (S3.19) hearing protection,
• NIOSH/OSHA/MSHA respiratory protection.

Important Safety Instructions for All
Battery Chargers
SAVE THESE INSTRUCTIONS: This manual contains important
safety and operating instructions for battery chargers.
• Before using charger, read all instructions and cautionary markings
on charger, battery pack, and product using battery pack.
DANGER: Electrocution hazard. 120 volts are present at charging
terminals. Do not probe with conductive objects. Electric shock or
electrocution may result.
WARNING: Shock hazard. Do not allow any liquid to get inside
charger. Electric shock may result.
CAUTION: Burn hazard. To reduce the risk of injury, charge only
DEWALT rechargeable batteries. Other types of batteries may burst
causing personal injury and damage.
NOTICE: 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, 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.
•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 DEWALT 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.
English

•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.

•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.

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.
English

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.
