The vibration and/or noise emission level given in this information
sheet has been measured in accordance with a standardised test
given in EN60745 and may be used to compare one tool with
another. It may be used for a preliminary assessment ofexposure.

WARNING: The declared vibration and/or noise emission
level represents the main applications of the tool. However



if the tool is used for different applications, with different
accessories or poorly maintained, the vibration and/or
noise emission may differ. This may significantly increase
the exposure level over the total workingperiod.

An estimation of the level of exposure to vibration and/or
noise should also take into account the times when the tool
is switched off or when it is running but not actually doing
the job. This may significantly reduce the exposure level
over the total workingperiod.

Identify additional safety measures to protect the operator
from the effects of vibration and/or noise such as: maintain
the tool and the accessories, keep the hands warm
(relevant for vibration), organisation of workpatterns.

GENERAL POWER TOOL SAFETY WARNINGS

WARNING: Read all safety warnings, instructions,
illustrations and specifications provided with this



power tool. Failure to follow all instructions listed below
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

DCB104 DCB107 DCB112 DCB113 DCB115 DCB116 DCB117 DCB118 DCB132 DCB119

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 residual current device (RCD)
protected supply. Use of an RCD 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 a 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 energising power tools that have the switch on
invitesaccidents.

ENGLISH

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

jewellery. Keep your hair and clothing away from
moving parts. Loose clothes, jewellery 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.

h ) Do not let familiarity gained from frequent use of

tools allow you to become complacent and ignore
tool safety principles. A careless action can cause severe

injury within a fraction of asecond.

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 remove the battery pack, if detachable, 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 and accessories. 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.

h ) Keep handles and grasping surfaces dry, clean and

free from oil and grease. Slippery handles and grasping
surfaces do not allow for safe handling and control of the
tool in unexpectedsituations.

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.

e ) Do not use a battery pack or tool that is damaged or

modified. Damaged or modified batteries may exhibit
unpredictable behaviour resulting in fire, explosion or risk
ofinjury.

f ) Do not expose a battery pack or tool to fire or

excessive temperature. Exposure to fire or temperature
above 130°C may causeexplosion.

g ) Follow all charging instructions and do not charge

the battery pack or tool outside the temperature
range specified in the instructions. Charging

improperly or at temperatures outside the specified range
may damage the battery and increase the risk offire.

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.

b ) Never service damaged battery packs. Service

of battery packs should only be performed by the
manufacturer or authorized serviceproviders.

Additional Specific Safety Rules for Drills/
Drivers/Hammerdrills

• Wear ear protectors when impact drilling. Exposure to

noise can cause hearingloss.

• Use the auxiliary handles, if supplied with the tool. Loss

of control can cause personalinjury.

• Brace the tool properly before use. This tool produces a

high output torque and without properly bracing the tool
during operation, loss of control may occur resulting in
personalinjury.

• Hold the power tool by insulated gripping surfaces when

performing an operation where the cutting accessory
may contact hidden wiring. Cutting accessory or fasteners

contacting a “live” wire may make exposed metal parts of the
power tool “live” and could give the operator an electricshock.

ENGLISH

Safety Instructions When Using Long
Drill Bits

• Never operate at higher speed than the maximum
speed rating of the drill bit. At higher speeds, the bit is likely

to bend if allowed to rotate freely without contacting the
workpiece, resulting in personalinjury.

• Always start drilling at low speed and with the bit tip
in contact with the workpiece. At higher speeds, the bit is
likely to bend if allowed to rotate freely without contacting the
workpiece, resulting in personalinjury.

• Apply pressure only in direct line with the bit and do not
apply excessive pressure. Bits can bend causing breakage or
loss of control, resulting in personalinjury.

• 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 ear protectors when hammering for extended
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hammerdrilling.

• Wear safety goggles or other eye protection. Hammering
and drilling operations cause chips to fly. Flying particles can
cause permanent eyedamage.

• Hammer bits and tools get hot during operation. Wear
gloves when touchingthem.

Residual Risks

In spite of the application of the relevant safety regulations
and the implementation of safety devices, certain residual risks
cannot be avoided. These are:

• Impairment ofhearing.

• Risk of personal injury due to flyingparticles.

• Risk of burns due to accessories becoming hot
duringoperation.

• Risk of personal injury due to prolongeduse.

SAVE THESE INSTRUCTIONS

* 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 by refusing tolight.

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 authorised servicecentre.

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

XR 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 lithium‑ion battery
pack on the charger until it is fullycharged.

The battery pack is not fully charged out of the carton. Before
using the battery pack and charger, read the safety instructions
below. Then follow charging proceduresoutlined.

READ ALL INSTRUCTIONS

• Do not charge or use battery in explosive atmospheres,
such as in the presence of flammable liquids, gases or
dust. Inserting or removing the battery from the charger may

ignite the dust orfumes.

• Never force battery pack into charger. Do not modify

battery pack in any way to fit into a non‑compatible
charger as battery pack may rupture causing serious
personalinjury.

• Charge the battery packs only in 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 fall below 4˚C (39.2˚F)
(such as outside sheds or metal buildings in winter), or
reach or exceed 40˚C (104˚F) (such as outside sheds or
metal buildings insummer).

• 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 persists, seek
medicalattention.

WARNING: Burn hazard. Battery liquid may be flammable
if exposed to spark orflame.



WARNING: Never attempt to open the battery pack for
any reason. If battery pack case is cracked or damaged,



do not insert into charger. Do not crush, drop or damage
battery pack. Do not use a battery pack or charger that
has received a sharp blow, been dropped, run over or

damaged in any way (i.e., pierced with a nail, hit with
a hammer, stepped on). Electric shock or electrocution
may result. Damaged battery packs should be returned to
service centre forrecycling.

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.

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.

Transportation

WARNING: Fire hazard. Transporting batteries can
possibly cause fire if the battery terminals inadvertently



come in contact with conductive materials. When
transporting batteries, make sure that the battery
terminals are protected and well insulated from
materials that could contact them and cause a short
circuit. NOTE: Lithium‑ion batteries should not be put in
checkedbaggage.

DEWALT batteries comply with all applicable shipping
regulations as prescribed by industry and legal standards which
include UN Recommendations on the Transport of Dangerous
Goods; International Air Transport Association (IATA) Dangerous
Goods Regulations, International Maritime Dangerous Goods
(IMDG) Regulations, and the European Agreement Concerning
The International Carriage of Dangerous Goods by Road
(ADR). Lithium‑ion cells and batteries have been tested to
section 38.3of the UN Recommendations on the Transport of
Dangerous Goods Manual of Tests andCriteria.

In most instances, shipping a DEWALT battery pack will be
excepted from being classified as a fully regulated Class
9Hazardous Material. In general, only shipments containing a
lithium‑ion battery with an energy rating greater than 100Watt
Hours (Wh) will require being shipped as fully regulated Class 9.
All lithium‑ion batteries have the Watt Hour rating marked on

andTransport.

Use Mode: When the FLEXVOLTTM battery stands alone or is in
a DEWALT 18V product, it will operate as an 18V battery. When
the FLEXVOLTTM battery is in a 54V or a 108V (two 54V batteries)
product, it will operate as a 54Vbattery.

Transport Mode: When the cap is attached to the FLEXVOLTTM
battery, the battery is in Transport mode. Keep the cap
forshipping.

When in Transport mode, strings
of cells are electrically
disconnected within the pack
resulting in 3batteries with a
lower Watt hour (Wh) rating as compared to 1battery with a
higher Watt hour rating. This increased quantity of 3batteries
with the lower Watt hour rating can exempt the pack from
certain shipping regulations that are imposed upon the higher
Watt hour batteries.

For example, the Transport
Wh rating might indicate
3x36Wh, meaning
3batteries of 36Wh each.
The Use Wh rating might
indicate 108Wh (1batteryimplied).

Storage Recommendations

1. The best storage place is one that is cool and dry away
from direct sunlight and excess heat or cold. For optimum
battery performance and life, store battery packs at room
temperature when not inuse.

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.

Labels on Charger and Battery Pack

2. For WOOD, use twist bits, spade bits, power auger bits or
hole saws. For METAL, use high‑speed steel twist drill bits
or hole saws. Use a cutting lubricant when drilling metals.
The exceptions are cast iron and brass which should be
drilleddry.

3. Always apply pressure in a straight line with the bit. Use
enough pressure to keep the drill bit 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.

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

2. When drilling, use just enough force on the hammer to
keep it from bouncing excessively. Prolonged and too much
force on the hammer will cause slower drilling speeds and
potentialoverheating.

3. Drill straight, keeping the bit at a right angle to the work. Do
not exert side pressure on the bit when drilling as this will
cause clogging of the bit flutes and a slower drillingspeed.

4. When drilling deep holes, if the hammer speed starts to
drop off, pull the bit partially out of the hole with the tool
still running to help clear debris from thehole.

5. For masonry, use carbide‑tipped bits or masonry bits. A
smooth, even flow of dust indicates the proper drillingrate.
