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.

If operating a powertool in a damp location is unavoidable,
use a ground fault circu# interrupter (GFCI) protected

supply. Use of a GFC/ 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 toors operation. If
damaged, have the power tool repaired before use. Many

accidents are caused by poorly maintained power tools.
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.

c) When battery pack is not in use, keep H 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 bums 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.

Additional Safety Rules for Rotary

Hammers

• Wear ear protectors. 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 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 loss of control.

• Wear safety goggles or other eye protection. Hammering
operations cause chips to fly.Flyingparticles can cause permanent
eye damage. Wear a dust mask or respirator for applications

that generate dust. Ear protection may be required for most

applications.

• Keep a firm grip on the tool at all times. Do not attempt

to operate this tool without holding # 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.

• 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.

• Do not recondition bits yourself. Chisel reconditioning should

be done by an authorized specialist. Improperly reconditioned

chisels could cause injury.

• Wear gloves when operating tool or changing bits. Accessible

metal parts on the tool and bits may get extremely hot during

operation. Small bits of broken material may damage bare hands.

• Never lay the tool down until the bit has come to a complete

stop. Moving bits could cause injury.

• Do not strike jammed bits with a hammer to dislodge them.
Fragments of metal or material chips could dislodge and cause

injury.

• Do not overheat the bit (discoloration) while grinding a new

edge. Badly worn chisels require reforging. Do not reharden and

temper the chisel

• Air vents often cover moving parts and should be avoided.
Loose clothes, jewelry or long hair can be caught in moving parts.

i_,WARNING: ALWAYS use safety glasses. Everyday eyeglasses are
NOTsafety 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 $12.6 ($3.19) hearing protection,

• NIOSH/OSHA/MSHA respiratory protection.

A WARNING: Some dust created by power sanding, sawing,

grinding, drilling, and other construction activities contains chemicals

known to the State of California 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 chromMm 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,

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.
i_,WARNING: Use of this tool can generate and/or disperse 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.

,_ WARNING: Always wear proper personal hearing protection
that conforms to ANSI $12.6 ($3.19) during use. Under some

conditions and duration of use, noise from this product may
contribute to hearing loss.

_ CAUTION: When not in use, place tool on its side on a stable
surface where it will not cause a tripping or falling hazard.

product kit boxes, drawers, etc., with loose nails, screws, keys, etc.

without battery cap. Transporting batteries can possibly cause
fires if the battery terminals inadvertently come in contact
with conductive materials such as keys, coins, hand tools
and the like. The U.S. Department of Transportation Hazardous
Material Regulations (HMR) actually prohibit transporting batteries

in commerce or on airplanes (i.e., packed in suitcases and carry-on
luggage) UNLESS they are properly protected from short circuits.
So when transporting individual batteries, make sure that the battery
terminals are protected and well insulated from materials that could

contact them and cause a short circuit.

SPECIFIC SAFETY INSTRUCTIONS FOR LITHIUM ION (Li-lon)

• 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. Toxic fumes and materials are created when

lithium ion battery packs are burned.

• If battery contents come into contact with the skin,

immediately wash area with mild soap and water. If battery
liquid gets into the eye, rinse water over the open eye for 15
minutes or until irritation ceases. If medical attention is needed,

the battery electrolyte is composed of a mixture of liquid organic
carbonates and lithium salts.

• Contents of opened battery cells may cause respiratory

irritation. Provide fresh air, If symptoms persist, seek medical
attention.

_&WARNING: Bum hazard. Battery liquid may be flammable if
exposed to spark or flame.

The RBRC TM Seal

The RBRC TM (Rechargeable Batted/ Recycling Corporation) Seal on
the nickel cadmium, nickel metal hydride or lithiumion

batteries (or battery packs) indicate that the costs to
recycle these batteries (or battery packs) at the end of

their useful life have already been paid by DEWALT. In
some areas, it is illegal to place spent nickel cadmium,

nickel metal hydride or lithium ion batteries in the trash
or municipal solid waste stream and the RBRC program
provides an environmentally conscious alternative.

RBRCTM in cooperation with DEWALT and other battery users, has

established programs in the United States and Canada to facilitate
the collection of spent nickel cadmium, nickel metal hydride or lithium

ion batteries. Help protect our environment and conserve natural
resources by returning the spent nickel cadmium, nickel metal hydride

on charger, battery pack, and product using battery pack.

WARNING: Shock hazard. Do not allow any liquid to get inside the
charger. Electric shock may result.
i_,CAUTION: Bum hazard. To reduce the risk of injury, charge only
DEWALT rechargeable battery packs. Other types of batteries may
overheat and burst resulting in personal injury and property 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.

• 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

Charger Diagnostics

This charger is designed to detect certain problems that can arise
with the battery packs or the charger. Problems are indicated by the

three red lights flashing together in different patterns.

PROBLEM POWERLINE

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. The three red lights will flash together
with two fast blinks followed by a pause. This indicates that the

power souce is out of limits.

BAD BATTERY

The charger can detect a weak or damaged battery. The three red
lights will flash together with rapid blinking. The battery will no longer

charge and should be returned to a service center or a collection site
for recycling.

BAD CHARGER

The charger will detect if it is not functioning properly. The three red
lights will flash together with one fast blink followed by a long
blink. The charger will no longer work and should be returned to an
authorized service center or replaced.

LEAVING THE BATTERY IN THE CHARGER

The charger and battery pack can be left connected with the red
lights glowing indefinitely. The charger will keep the battery pack

fresh and fully charged. This charger features an automatic tune-up
mode which equals or balances the individual cells in the battery

pack to allow it to function at peak capacity. Battery packs should
be tuned up weekly or whenever the battery no longer delivers the

same amount of work. To use the automatic tune-up mode, place the
battery pack in the charger and leave it for at least 8 hours.

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 o_ 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,aluminumfoil,oranybuildupofmetallicparticlesshouldbe
