The vibration 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 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 emission
may differ. This may significantly increase the exposure
level over the total working period.
An estimation of the level of exposure to vibration 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 such as: maintain the tool
and the accessories, keep the hands warm, organisation
of work patterns.

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.
4
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 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, clothing and gloves 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.
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
English

f )
g )
will do the job better and safer at the rate for which it
was designed.
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.
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.
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.
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.
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 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.
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 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 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.
5
English
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.
•
Electrical Safety
•
The electric motor has been designed for one voltage only.
Always check that the battery pack voltage corresponds to the
voltage on the rating plate. Also make sure that the voltage of
your charger corresponds to that of your mains.
Your DeWALT charger is double insulated in
accordance with EN60335; therefore no earth wire
is required.
If the supply cord is damaged, it must be replaced by a
specially prepared cord available through the DeWALT
service organisation.

charger. This will reduce risk of damage to electric plug
and cord.
Make sure that 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.
Do not place any object on top of charger or place
the charger on a soft surface that might block the
ventilation slots and result in excessive internal heat.
Place the charger in a position away from any heat source. The
charger is ventilated through slots in the top and the bottom
of the housing.
Do not operate charger with damaged cord or plug—
have them replaced immediately.
Do not operate charger if it has received a sharp blow,
been dropped, or otherwise damaged in any way. Take it
to an authorised service centre.
Do not disassemble charger; take it to an authorised
service centre when service or repair is required. Incorrect
reassembly may result in a risk of electric shock, electrocution
or fire.
In case of damaged power supply cord the supply cord must
be replaced immediately by the manufacturer, its service agent
or similar qualified person to prevent any hazard.
Disconnect the charger from the outlet before
attempting any cleaning. This will reduce the risk of
electric shock. Removing the battery pack will not reduce
this risk.
NEVER attempt to connect two chargers together.
The charger is designed to operate on standard
230V household electrical power. Do not attempt to
use it on any other voltage. This does not apply to the
vehicular charger.
Using an Extension Cable
An extension cord should not be used unless absolutely
necessary. Use an approved extension cable suitable for
the power input of your charger (see Technical Data). The
minimum conductor size is 1 mm2; the maximum length
is 30 m.
When using a cable reel, always unwind the cable completely.
Charging a Battery (Fig. B)
1. Plug the charger into an appropriate outlet before inserting
battery pack.
2. Insert the battery pack 1 into the charger, making sure the
battery pack is fully seated in the charger. The red (charging)
light will blink repeatedly indicating that the charging
process has started.

cleaning solutions. Never let any liquid get inside the tool;
never immerse any part of the tool into a liquid.
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 or by
displaying 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 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.
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
Battery Packs

English
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.
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
the pack. Furthermore, due to regulation complexities, DeWALT
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
8
implied, is given. It is the buyer’s responsibility to ensure that its
activities comply with the applicable regulations.
Transporting the FLEXVOLTTM Battery
The DeWALT FLEXVOLTTM battery has two modes: Use
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 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:

Overload Clutch
In case of jamming of a drill bit, the drive to the drill spindle is
interrupted. Because of the resulting forces, always hold the
tool with both hands and take a firm stance. After the overload,
release and depress the trigger to re-engage drive.
Mechanical Clutch
These tools are fitted with a mechanical clutch. The indication
that the clutch has activated will be an audible ratcheting
together with increased vibration.

Anti-Rotation System (Fig. D)
Fuel Gauge Battery Packs
In addition to the clutch, an anti-rotation system offers increased
user comfort and safety through an on-board, anti-rotation
technology capable of detecting if the user loses control of
the hammer. When a jam is detected, the torque and speed are
reduced instantly. This feature prevents self rotation of the tool
reducing the occurrence of wrist injuries.
The anti-rotation system indicator 11 will illuminate to
indicate status.
Some DeWALT battery packs include a fuel gauge which
consists of three green LED lights that indicate the level of
charge remaining in the battery pack.
To actuate the fuel gauge, press and hold the fuel gauge
button 12 . A combination of the three green LED lights will
illuminate designating the level of charge left. When the level
of charge in the battery is below the usable limit, the fuel gauge
will not illuminate and the battery will need to be recharged.
NOTE: The fuel gauge is only an indication of the charge left on
the battery pack. It does not indicate tool functionality and is
subject to variation based on product components, temperature
and end-user application.

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.
ASSEMBLY AND ADJUSTMENTS
WARNING: To reduce the risk of serious personal
injury, turn tool off and disconnect battery pack
before making any adjustments or removing/
installing attachments or accessories. An accidental
start-up can cause injury.

Side Handle (Fig. A)
WARNING: To reduce the risk of personal injury, ALWAYS
operate the tool with the side handle properly installed.
Failure to do so may result in the side handle slipping
during tool operation and subsequent loss of control. Hold
tool with both hands to maximize control.
The side handle 3 clamps to the front of the gear case and
may be rotated 360˚ to permit right- or left-hand use. The side
handle must be tightened sufficiently to resist the twisting
action of the tool if the accessory binds or stalls. Be sure to grip
the side handle at the far end to control the tool during a stall.
To loosen side handle, rotate counterclockwise.
Bit and Bit Holder
WARNING: Burn Hazard. ALWAYS wear gloves when
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.
The hammerdrill can be fitted with different bits depending on
the desired application. Use sharp drill bits only.
SDS-Max Bit Holder (Fig. A, C, F)
To insert a drill bit or other accessory:
1. Insert the shank of the bit about 19 mm into SDS-Max tool
holder 8 .
2. Push and rotate bit until it locks in place. The bit will be
securely held.
3. To release bit, pull the sleeve 9 back and remove the bit.

operable positions in between. It may be necessary to briefly
run the motor after having changed from 'hammering only' to
'rotary' modes in order to align the gears.
Performing an Application (Fig. A, F)
WARNING: TO REDUCE THE RISK OF PERSONAL
INJURY, ALWAYS ensure workpiece is anchored or
clamped firmly. If drilling thin material, use a wood “backup” block to prevent damage to the material.
WARNING: Always wait until the motor has come to
a complete standstill before changing the direction
of rotation.
1. Choose and install the appropriate chuck, adapter, and/or
bit onto to the tool. Refer to Bit and Bit Holders.
2. Using the mode selector dial 5 , select the mode
appropriate to desired application. Refer to
Operation Modes.
3. Adjust the side handle 3 as required.
4. Place the bit/chisel on the desired location.
5. Depress the trigger switch 4 .
NOTE: Depending on your tool, depressing the trigger
switch activates a worklight 10 designed to illuminate the
immediate work surface. Refer to Description. The worklight
will automatically turn off 20 seconds after the trigger
switch is released.
Recommendations for Tool Operation
• When drilling, always apply pressure in a straight line with
the bit, but do not push hard enough to stall the motor or
deflect the bit. A smooth even flow of material indicates the
proper drilling rate.
• Your hammer can be used for dry diamond drilling into
masonry up to 100 mm. For diamond drilling above this
diameter in masonry and regular large diameter diamond
drilling in masonry and concrete, we advise the use of
a dedicated diamond core drill. Follow the core bit or
manufacturer’s recommendations for using the accessory.
NOTE: Always use core bits with integral centredrill systems
and ensure the RPM (speed) of the hammer does not
exceed the maximum rated RPM of the diamond core.
-- Insert the centredrill into its holder in the centre of the
core bit.
-- Remove and unplug the machine.
-- Remove the centredrill from its holder.
-- Plug the machine in and insert the core bit into
the workpiece.
WARNING:
• Do not use this tool to mix or pump easily combustible
or explosive fluids (benzine, alcohol, etc.).
• Do not mix or stir inflammable liquids
labelled accordingly.
