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 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.

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

ofmoving 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.

t) 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) BATFERY TOOL USE AND CARE

a) Recharge only with the charger specified by the

manufacturer. A charger that is suitable for one type of

batterypackmaycreateariskoffirewhenusedwithanother
batterypack.

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 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 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 bums.

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 Specific Safety Rules

• Hold power tool by insulated gripping surfaces when
performing an operation where the fastener may contact

hidden wiring. Fasteners 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 and

drilling operations cause chips to fly. Flying particles can cause

permanent eye damage.

• Accessories and tools get hot during operation. Wear gloves
when touching them.

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

• Do not operate this tool for long periods of time. Vibration
caused by tool action may be harmful to your hands and arms.
Use gloves to provide extra cushion and limit exposure by taking
frequent rest periods.

i_ 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 $12.6 ($3. 19) hearing protection,

• NIOSH/OSHA/MSHA respiratory protection.

_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 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,

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.

_ 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.

Some tools with large battery packs will stand upright on the battery

pack but may be easily knocked over.

When ordering replacement battery packs, be sure to include the
catalog number and voltage. Consult the chart at the end of this

manual for compatibility of chargers and battery packs.
The battery pack is not fully charged out of the carton. Before using

the battery pack and charger, read the safety instructions below and
then follow charging procedures outlined.

READ ALL INSTRUCTIONS

• Do not charge or use the battery pack in explosive atmo-

spheres, such as in the presence of flammable liquids,
gases or dusL Inserting or removing the battery pack from the

charger may ignite the dust or fumes.

• NEVER force the battery pack into the charger. DO NOT

modify the battery pack in any way to fit into a non-compat-
ible charger as battery pack may rupture causing serious

personal injury. Consult the chart at the end of this manual for

compatibility of batteries and chargers.

• Charge the battery packs only in designated DEWALT 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 (40 °C)
(such as outside sheds or metal buildings in summer). For

best life store battery packs in a cool, dry location.

NOTE: Do not store the battery packs in a tool with the trig-
ger switch locked on. Never tape the trigger switch in the

ON position.

i_WARNING: Fire hazard. Never attempt to open the battery pack
for any reason. If the battery pack case is cracked or damaged, do

not insert into the charger. Do not crush, drop or damage the battery

pack. Do not use a battery pack or charger that has received a sharp

blow,beendropped,runoverordamagedinanyway(e.g.,pierced
withanail,hitwithahammer,steppedon).Damagedbatterypacks

shouldbereturnedtotheservicecenterfor recycling.

A WARNING: Fire hazard. Do not store or carry the battery

pack so that metal objects can contact exposed battery

terminals. For example, do not place the battery pack in aprons,

pockets, tool boxes, product kit boxes, drawers, etc., with loose

nails, screws, keys, etc. 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 US Department of Transportation Hazardous

Material Regulations (HMR) actually prohibit transporting batteries in
commerce or on airplanes (e.g., packed in suitcases and carry-on

luggage) UNLESS they are properly protected from short circuits.
So when transporting individual battery packs, 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, imme-
diately wash area with mild soap and water, ff 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 irri-
tation. Provide fresh air. If symptoms persist, seek medical atten-

tion.

_WARNING: Bum hazard. Battery liquid may be flammable if
exposed to spark or flame.

The RBRC TM Seal

The RBRCTM (Rechargeable Battery Recycling Corporation) Seal on the
nickel cadmium, nickel metal hydride or lithium ion

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

or lithium ion batteries to an authorized DEWALT 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 All
Battery Chargers

SAVE THESE INSTRUCTIONS: This manual contains important

safety and operating instructions for battery chargers.

• Before using the charger, read all instructions and cautionary mark-
ings on the charger, battery pack and product using the 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 into the

power supply, 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 the charger cavities. Always unplug

the charger from the power supply when there is no battery pack in the
cavity, Unplug the charger before attempting to clean.

• DO NOT attempt to charge the battery pack with any char-
gers other than the ones in this manual The charger and bat-

tery 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 the charger to rain or snow.

• Pull by the plug rather than the cord when disconnecting

the charger. This will reduce the risk of damage to the electric plug

and cord.

• Make sure that the 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 neces-
sary. Use of improper extension cord could result in risk of fire,

electric shock or electrocution.

• When operating a charger outdoors, always provide a dry

location and 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 lower the gauge number, the heavier the cord.

Charge Indicators

This charger is designed to detect certain problems that can arise,

Problems are indicated by the red light flashing at a fast rate, If this
occurs, re-insert the battery pack into the charger. If the problem
persists, try a different battery pack to determine if the charger is
working properly. 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 and the battery pack

tested at an authorized service center.

HOT/COLD DELAY

This charger has a hot/cold delay feature: when the charger detects a
battery that is hot, it automatically starts a 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/cold delay mode.

LEAVING THE BATTERY PACK IN THE CHARGER

The charger and battery pack can be left connected with the charge
indicator showing Pack Charged.

WEAK BA'R'ERY PACKS: Weak batteries will continue to function
but should not be expected to perform as much work.

FAULTY BATTERY PACKS: This charger will not charge a faulty
battery pack. The charger will indicate faulty battery pack by refusing

to light or by displaying problem pack or charger.

NOTE: This could also mean a problem with a charger.
PROBLEM POWER LINE

Some chargers have a Problem Powerline 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.

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 the 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. A cold battery pack will charge at about half the rate of a warm
battery pack. The battery pack will charge at that slower rate
throughout the entire charging cycle and will not return to
maximum charge rate even if the battery pack warms.

4. 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 the 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.

5. 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 effect on the battery pack.

6. 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 the charger before

attempting to clean.

7. Do not freeze or immerse the charger in water or any other liquid.

i_ WARNING: Shock hazard. Don't allow any liquid to get inside the

charger. Electric shock may result.
i_WARNING: Bum hazard. Do not submerge the battery pack in

any liquid or allow any liquid to enter the battery pack. 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.

Storage Recommendations

1. The best storage place is one that iscool and dry, away from direct
sunlight and excess heat or cold.

2. Press switch to start operation. Release switch to stop operation.
Always check torque with a torque wrench, as the fastening torque
is affected by many factors including the following:

11

• Voltage: Low voltage, due to a nearly discharged battery, will

reduce fastening torque.

• Accessory size: Failure to use the correct accessory size will
cause a reduction in fastening torque.

• Bolt size: Larger bolt diameters generally require higher
fastening torque. Fastening torque will also vary according to
length, grade, and torque coefficient.

• Bolt: Ensure that all threads are free of rust and other debris to
allow proper fastening torque.

• Material: The type of material and surface finish of the material
will affect fastening torque.

• Fastening time: Longer fastening time results in increased
fastening torque. Using a longer fastening time than
recommended could cause the fasteners to be overstressed,
stripped or damaged.
