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 mains­operated (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

2

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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 Safety Warnings

• 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 and drilling operations cause chips to fly.
Flying particles can cause permanent eye damage.

• 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.

ENGLISH

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

caught in movingparts.

Additional Safety Information

Important Safety Instructions for All
Battery Chargers

WARNING: Read all safety warnings and all
instructions for the battery pack, charger and



power tool. Failure to follow the warnings and
instructions may result in electric shock, fire and/
or serious injury.

• 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

rechargeable batteries.

ENGLISH

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
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.

* DCB107, DCB112, DCB113, DCB115, DCB118, DCB132:

The red light will continue to blink, but a yellow indicator
light will be illuminated during this operation. Once the
battery pack has reached an appropriate temperature, the
yellow light will turn off and the charger will resume the
charging procedure.

The compatible charger(s) will not charge a faulty battery
pack. The charger will indicate faulty battery pack by
refusing to light or by displaying a problem pack or charger
blink pattern.

NOTE: This could also mean a problem with a charger.
If the charger indicates a problem, take the charger and

battery pack to be tested at an authorized service center.

Hot/Cold Pack Delay

When the charger detects a battery pack that is too hot
or too cold, it automatically starts a Hot/Cold Pack Delay,
suspending charging until the battery pack has reached an
appropriate temperature. The charger then automatically
switches to the pack charging mode. This feature ensures
maximum battery pack life.

A cold battery pack will charge at a slower rate than 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.

The DCB118 charger is equipped with an internal fan
designed to cool the battery pack. The fan will turn on
automatically when the battery pack needs to be cooled.

Never operate the charger if the fan does not operate
properly or if ventilation slots are blocked. Do not permit
foreign objects to enter the interior of the charger.

Electronic Protection System

Li-Ion tools are designed with an Electronic Protection
System that will protect the battery pack against
overloading, overheating or deep discharge.

The tool will automatically turn off if the Electronic
Protection System engages. If this occurs, place the lithium­ion battery pack on the charger until it is fully charged.

Wall Mounting

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,
and away from a corner or other obstructions which may
impede air flow. Use the back of the charger as a template
for the location of the mounting screws on the wall. Mount
the charger securely using drywall screws (purchased
separately) at least 1" (25.4 mm) long, with a screw head
diameter of 0.28–0.35" (7–9mm), screwed into wood to an
optimal depth leaving approximately 7/32" (5.5 mm) of the
screw exposed. Align the slots on the back of the charger
with the exposed screws and fully engage them in the slots.

Charger Cleaning Instructions

WARNING: Shock hazard. Disconnect the charger
from the AC outlet before cleaning. Dirt and grease



may be removed from the exterior of the charger using
a cloth or soft non-metallic brush. Do not use water or
any cleaning solutions.

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 +104°F (+40°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. 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.

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 effect on the battery pack.

5. 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.

ENGLISH

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

Storage Recommendations

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

2. For long storage, it is recommended to store a fully
charged battery pack in a cool dry place out of the
charger for optimal results.

NOTE: Battery packs should not be stored completely
depleted of charge. The battery pack will need to be
recharged before use.

1. Select the desired speed/torque range using the gear
shifter to match the speed and torque to the planned
operation. Turn the collar

2. Use sharp drill bits only. For MASONRY, such as brick,
cement, cinder block, etc., use carbide-tipped bits rated
for percussion drilling.

3. Always apply pressure in a straight line with the bit. Use
enough pressure to keep drill biting, but do not push
hard enough to stall the motor or deflect the bit.

4. Hold tool firmly with both hands to control the twisting
action of the drill. If model is not equipped with side
handle, grip drill with one hand on the handle and one
hand on the battery pack.

WARNING: Drill may stall if overloaded causing a
sudden twist. Always expect the stall. Grip the drill



firmly to control the twisting action and avoid injury.

5. IF THE DRILL STALLS, it is usually because it is being
overloaded or improperly used. RELEASE TRIGGER
IMMEDIATELY, remove drill bit from work, and
determine cause of stalling. DO NOT depress TRIGGER

ON AND OFF IN AN ATTEMPT TO START A STALLED
DRILL — THIS CAN DAMAGE THE DRILL.

6. To minimize stalling or breaking through the material,
reduce pressure on drill and ease the bit through the
last fractional part of the hole.

7. Keep the motor running when pulling the bit back out
of a drilled hole. This will help prevent jamming.
