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

J

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 circuff 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 tool's 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 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 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 Safety Rules for Oscillating

Multi-Tool

• Hold power tool by insulated gripping surfaces, when
performing an operation where the cutting accessory may
contact hidden wiring or its own cord. 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.

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

A 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.

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 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.

A 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.

A 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.

A 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.

• 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

trigger switch locked on. Never tape the trigger switch in
the ON position.

_ 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
lithMm 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 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
markings on the charger, battery pack and product using the

battery pack.

h_,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
DEiWALTrechargeable 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
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 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
necessary. 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 thegauge 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 inline voltage resulting inloss ofpower 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
DCB101

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.

DCB107, DCB112

The DCB107 and DCB112 chargers have a hot/cold delay feature.

When the charger detects a battery that is hot, it automatically delays
charging until the battery has cooled. When the charger detects a
battery that is cold, it automatically delays charging until the battery

has warmed.

The red light will continue to blink, but a yellow indicator light will be

illuminated during this operation. Once the battery has cooled, the
yellow light will turn off and the charger will resume the charging
procedure.

LEAVING THE BA'I-I'ERY PACK IN THE CHARGER

The charger and battery pack can be left connected with the charge

indicator showing Pack Charged.
WEAK BATTERY PACKS" Weak batteries will continue to function

but should not be expected to perform as much work.
FAULTY BA'rI'ERY 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 (DCB101)

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 isout of limits.

Wall Mounting

DCB107, DCB112

These chargers are designed to be wall mountable or to sit upright on

a table or work surface.

If wall mounting, locate the charger within reach of an electrical

outlet. Mount the charger securely using drywall screws at least

1" (25.4 mm) long, screwed into wood to an optimal depth leaving

approximately 7/32" (5.5 mm) of the screw exposed.

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;
