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.
English
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 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 SPECIFIC SAFETY RULES
Safety Warnings Common for Grinding
a ) This power tool is intended to function as a grinder.
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.
b ) Operations such as sanding, wire brushing, polishing
and cutting-off are not recommended to be
performed with this power tool. Operations for which
the power tool was not designed may create a hazard and
cause personal injury.
c ) Do not use accessories which are not specifically
designed and recommended by the tool
manufacturer. Just because the accessory can
be attached to your power tool, it does not assure
safe operation.
d ) The rated speed of the accessory must be at least
equal to the maximum speed marked on the power
tool. Accessories running faster than their rated speed can
break and fly apart.
e ) The outside diameter and the thickness of your
accessory must be within the capacity rating of
your power tool. Incorrectly sized accessories can not be
adequately guarded or controlled.
f ) The arbour size of wheels, flanges, backing pads or
any other accessory must properly fit the spindle of
the power tool. Accessories with arbour holes that do
not match the mounting hardware of the power tool will
run out of balance, vibrate excessively and may cause loss
of control.
g ) Mandrel mounted wheels or other accessories must
be fully inserted into the collet or chuck. If the mandrel
is insufficiently held and/or the overhang of the wheel is
too long, the mounted wheel may become loose and be
ejected at high velocity.
h ) Do not use a damaged accessory. Before each use
inspect the accessory such as abrasive wheel for
chips and cracks, backing pad for cracks, tear or
excess wear, wire brush for loose or cracked wires.
If power tool or accessory is dropped, inspect for
damage or install an undamaged accessory. After
inspecting and installing an accessory, position
yourself and bystanders away from the plane of
the rotating accessory and run the power tool at
maximum no-load speed for one minute. Damaged
accessories will normally break apart during this test time.
i ) Wear personal protective equipment. Depending on
application, use face shield, safety goggles or safety
glasses. As appropriate, wear dust mask, hearing
protectors, gloves and workshop apron capable of
stopping small abrasive or workpiece fragments.
The eye protection must be capable of stopping flying
debris generated by various operations. The dust mask or
respirator must be capable of filtrating particles generated
5
English
by your operation. Prolonged exposure to high intensity
noise may cause hearing loss.
j ) Keep bystanders a safe distance away from work
area. Anyone entering the work area must wear
personal protective equipment. Fragments of
workpiece or of a broken accessory may fly away and
cause injury beyond immediate area of operation.
k ) Hold the power tool by insulated gripping surfaces
only, when performing an operation where the
cutting tool may contact hidden wiring. Contact
with a "live" wire will also make exposed metal parts
of the power tool "live" and could give the operator an
electric shock.
l ) Always hold the tool firmly in your hand(s) during
start up. The reaction torque of the motor, as it
accelerates to full speed, can cause the tool to twist.
m ) Use clamps to support workpiece whenever
practical. Never hold a small workpiece in one hand
and the tool in the other while in use. Clamping a
small workpiece allows you to use your hand(s) to control
the tool. Round material such as dowel rods, pipes or
tubing have a tendency to roll while being cut, and may
cause the bit to bind or jump toward you.
n ) Never lay the power tool down until the accessory
has come to a complete stop. The spinning accessory
may grab the surface and pull the power tool out of
your control.
o ) After changing bits or making any adjustments,
make sure the collet nut, chuck or any other
adjustment devices are securely tightened. Loose
adjustment devices can unexpectedly shift, causing
loss of control, loose rotation components will be
violently thrown.
p ) Do not run the power tool while carrying it at your
side. Accidental contact with the spinning accessory
could snag your clothing, pulling the accessory into
your body.
q ) Regularly clean the power tool’s air vents. The
motor’s fan will draw the dust inside the housing and
excessive accumulation of powdered metal may cause
electrical hazards.
r ) Do not operate the power tool near flammable
materials. Sparks could ignite these materials.
s ) Do not use accessories that require liquid coolants.
Using water or other liquid coolants may result in
electrocution or shock.
FURTHER SAFETY INSTRUCTIONS FOR ALL
OPERATIONS
Causes and Operator Prevention
of Kickback
Kickback is a sudden reaction to a pinched or snagged rotating
wheel, backing pad, brush or any other accessory. Pinching or
snagging causes rapid stalling of the rotating accessory which
6
in turn causes the uncontrolled power tool to be forced in the
direction opposite of the accessory’s rotation at the point of
the binding.
For example, if an abrasive wheel is snagged or pinched by the
workpiece, the edge of the wheel that is entering into the pinch
point can dig into the surface of the material causing the wheel
to climb out or kick out. The wheel may either jump toward or
away from the operator, depending on direction of the wheel’s
movement at the point of pinching. Abrasive wheels may also
break under these conditions.
Kickback is the result of tool misuse and/or incorrect operating
procedures or conditions and can be avoided by taking proper
precautions as given below:
a ) Maintain a firm grip on the power tool and position
your body and arm to allow you to resist kickback
forces. Always use auxiliary handle, if provided, for
maximum control over kickback or torque reaction
during start up. The operator can control torque reaction
or kickback forces, if proper precautions are taken.
b ) Use special care when working corners, sharp edges
etc. Avoid bouncing and snagging the accessory.
Corners, sharp edges or bouncing have a tendency to
snag the rotating accessory and cause loss of control
or kickback.
c ) Do not attach a saw chain woodcarving blade or
toothed saw blade. Such blades create frequent kickback
and loss of control.
d ) Always feed the bit into the material in the same
direction as the cutting edge is exiting from the
material (which is the same direction as the chips are
thrown). Feeding the tool in the wrong direction causes
the cutting edge of the bit to climb out of the work and
pull the tool in the direction of this feed.
e ) When using rotary files, cut off wheels, high-speed
cutters or tungsten carbide cutters, always have the
work securely clamped. These wheels will grab if they
become slightly canted in the groove, and can kickback.
When a cut-off wheel grabs, the wheel itself usually
breaks. When a rotary file, high speed cutter or tungsten
carbide cutter grabs, it may jump from the groove and you
could lose control of the tool.
Safety Warnings Specific for Grinding and
Cutting-Off Operations
a ) Use only wheel types that are recommended for your
power tool and only for recommended applications.
For example: Do not grind with the side of a cut-off
wheel. Abrasive cut-off wheels are intended for peripheral
grinding, side forces applied to these wheels may cause
them to shatter.
b ) For threaded abrasive cones and plugs use only
undamaged wheel mandrels with an unrelieved
shoulder flange that are of a correct size and length.
Proper mandrels will reduce the possibility of breakage.
c ) Do not "jam" a cut-off wheel or apply excessive
pressure. Do not attempt to make an excessive depth
English
d )
e )
f )
g )
h )
of cut. Overstressing the wheel increases the loading and
susceptibility to twisting or snapping of the wheel in the
cut and the possibility of kickback ort wheel breakage.
Do not position your hand in line with or behind
a rotating wheel. When the wheel, at the point of
operation, is moving away from your hand, the possible
kickback may propel the wheel and the power tool directly
at you.
When wheel is pinched, snagged or when
interrupting a cut for any reason, switch off the
power tool and hold the power tool motionless until
the wheel comes to a complete stop. Never attempt
to remove the cut-off wheel from the cut while the
wheel is in motion otherwise kickback may occur.
Investigate and take corrective action to eliminate the
cause of wheel pinching or snagging.
Do not restart the cutting operation in the
workpiece. Let the wheel reach full speed and
carefully re-enter the cut. The wheel may bind, walk up
or kickback if the power tool is restarted in the workpiece.
Support panels or any oversized workpiece to
minimize the risk of wheel pinching and kickback.
Large workpieces tend to sag under their own weight.
Supports must be placed under the workpiece near the line
of the cut and the edge of the workpiece on both sides of
the wheel.
Use extra caution when making a "pocket cut" into
existing walls or other blind areas. The protruding
wheel may cut gas or water pipes, electrical wiring or
objects that can cause kickback.
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.
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.

Charging a Battery (Fig. A)
1. Plug the charger into an appropriate outlet before inserting
battery pack.
2. Insert the battery pack 8 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.
3. The completion of charge will be indicated by the red
light remaining ON continuously. The battery pack is fully
charged and may be used at this time or left in the charger.
To remove the battery pack from the charger, push the
battery release button 9 on the battery pack.
NOTE: To ensure maximum performance and life of lithium-ion
battery packs, charge the battery pack fully before first use.
Charger Operation
Refer to the indicators below for the charge status of the

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 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
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.
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. Never let any liquid get inside the tool;
never immerse any part of the tool into a liquid.

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
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.
9
English
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).
Only for indoor use.
Discard the battery pack with due care for
the environment.
Charge DeWALT battery packs only with designated
DeWALT chargers. Charging battery packs other
than the designated DeWALT batteries with a
DeWALT 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).
TRANSPORT (with built-in transport cap). Example:
Wh rating indicates 3 x 36 Wh (3 batteries of 36 Wh).
Storage Recommendations
Battery Type
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.

WARNING: To reduce the risk of serious personal
injury, ALWAYS hold securely in anticipation of a
sudden reaction.
Proper hand position requires one hand on the tool body 10 ,
with the other hand on the neck of the die grinder 11 as shown
in Figure D.
Instructions for Use (Fig. C)
WARNING:
• Ensure all materials to be ground or cut are secured
in place.
• Use clamps or a vice to hold and support the
workpiece to a stable platform. It is important to
clamp and support the workpiece securely to prevent
the movement of the workpiece and loss of control.
Movement of the workpiece or loss of control may
create a hazard and cause personal injury.
• Secure the workpiece. A workpiece clamped with
clamping devices or in a vice is held more secure than
by hand.
• Support panels or any oversized workpiece to
minimize the risk of wheel pinching and kickback.
Large workpieces tend to sag under their own weight.
Supports must be placed under the workpiece near the
12
line of cut and near the edge of the workpiece on both
sides of the wheel.
• Always wear regular working gloves while operating
this tool.
• The gear case becomes very hot during use.
• Apply only a gentle pressure to the tool. Do not exert
side pressure on the disc.
• Avoid overloading. Should the tool become hot, let it
run a few minutes under no load condition.
• The best grinding results are achieved when setting
the machine at an angle of 90°. Move the machine
back and forth with moderate pressure. In this
manner, the workpiece will not become too hot, does
not discolour and no grooves are formed.
WARNING: Grasp tool firmly with both hands to maintain
control of the tool at start up and during use and until the
wheel or accessory stops rotating. Make sure the wheel
has come to a complete stop be­fore laying the tool down.
Put the work in a vise or clamp it securely. Use a face mask
over the nose and mouth if the operation raises dust. Treat
the wheel with respect. Do not jam the wheel into the work or
use unnecessary pressure. Grind only on the face of the wheel
unless you have a special wheel specifically make to permit
grinding on the side of the wheel.
Mounting an Accessory (Fig. A, B)
WARNING: Accessories must be rated at least equal to the
maximum speed marked on the tool. Accessories running
faster than their rated speed can break and fly apart.
WARNING: Accessories must be within the capacity rating
marked on the tool. Incorrectly sized accessories cannot be
adequately controlled.
WARNING: Do not use accessories with a mandrel length
exceeding 40 mm. Ensure that the exposed mandrel
length is no more than 10 mm after inserting accessory
into collet.
WARNING: Projectile hazard. Only use accessories
with shanks that match the installed collet. Smaller
shanks will not be secure and could become loose
during operation.
CAUTION: Never tighten the collet without first installing
an accessory in it. Tightening an empty collet, even by
hand, can damage the collet.
1. Hold the spindle 3 using the smaller spanner 5 provided.
2. Loosen the collet nut 4 by turning it counterclockwise.
3. Insert the shank of the accessory into the collet 7 .
4. Securely tighten the collet using the larger spanner
6 provided.
To remove the accessory, proceed in reverse order.
Metal Applications
WARNING: In extreme working conditions, conductive
dust can accumulate inside the machine housing when
working with metal. This can result in the protective
English
insulation in the machine becoming degraded with a
potential risk of an electrical shock.
To avoid build-up of metal swarf inside the machine, we
recommend to clear the ventilation slots on a daily basis.
