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

at

.

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 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

ENGLISH

5

ENGLISH

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.

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.

6

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

DeWALT

DeWALT

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 Safety Instructions for Rotary
Hammers

• Wear ear protectors. Exposure to noise can cause hearingloss.

• Use auxiliary handles supplied with the tool. Loss of control
can cause personalinjury.

• Hold power tools by insulated gripping surfaces when
performing an operation where the cutting tool may contact
hidden wiring. Contact with a “live” wire will make exposed
metal parts of the tool “live” and could give the operator an
electrical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. Flying particles 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 it with both hands. It
is recommended that the side handle be used at all times.
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. Tighten the side handle
securely beforeuse.

• 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.

• Slightly worn chisels can be resharpened bygrinding.

• Keep the power cord away from the rotating bit. Do not
wrap the cord around any part of your body. An electric cord
wrapped around a spinning bit may cause personal injury and
loss ofcontrol.

Residual Risks

The following risks are inherent to the use of rotary hammers:

• Injuries caused by touching the rotating parts or hot parts of
thetool.

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 squeezing fingers when changing theaccessory.

• Health hazards caused by breathing dust developed when
working in concrete and/ormasonry.

SAVE THESE INSTRUCTIONS

Chargers

Charge Indicators

Charging

Fully Charged

Hot/Cold Pack Delay*

* 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

DeWALT

DeWALT

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.

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 25.4mm long
with a screw head diameter of 7–9mm, screwed into wood to
an optimal depth leaving approximately 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.

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.

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

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
the pack. Furthermore, due to regulation complexities,
does not recommend air shipping lithium-ion battery packs
alone regardless of Watt Hour rating. Shipments of tools with
batteries (combo kits) can be air shipped as excepted if the Watt
Hour rating of the battery pack is no greater than 100Whr.

Regardless of whether a shipment is considered excepted
or fully regulated, it is the shipper's responsibility to consult
the latest regulations for packaging, labeling/marking and
documentationrequirements.

The information provided in this section of the manual is
provided in good faith and believed to be accurate at the time
the document was created. However, no warranty, expressed or
implied, is given. It is the buyer’s responsibility to ensure that its
activities comply with the applicableregulations.

Transporting the FLEXVOLT

The

FLEXVOLTTM battery has two modes: Use

TM

Battery

andTransport.
Use Mode: When the FLEXVOLT

a

18V product, it will operate as an 18V battery. When

TM

battery stands alone or is in

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 FLEXVOLT
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

Example of Use and Transport Label Marking

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

In addition to the pictographs used in this manual, the labels
on the charger and the battery pack may show the following
pictographs:

Read instruction manual beforeuse.

theenvironment.

Charge

than the designated

battery packs only with designated

chargers. Charging battery packs other

batteries with a

charger may make them burst or lead to

other dangeroussituations.

Do not incinerate the batterypack.

USE (without transport cap). Example: Wh rating
indicates 108 Wh (1 battery with 108 Wh).

Active Vibration Control

For best vibration control, hold the tool as described in Proper
HandPosition.

The active vibration control neutralises rebound vibration from
the hammer mechanism. Lowering hand and arm vibration,
it allows more comfortable use for longer periods of time and
extends the life of theunit.

The hammer only needs enough pressure to engage the active
vibraton control. Applying too much pressure will not make
the tool drill or chip faster and active vibration control will
notengage.
