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.
The term “power tool” in the warnings refers to your mainsoperated (corded) power tool or battery-operated (cordless)
power tool.
1) Work area safety
a ) Keep work area clean and well lit. Cluttered or dark
areas invite accidents.
b ) Do not operate power tools in explosive
atmospheres, such as in the presence of flammable
liquids, gases or dust. Power tools create sparks which
may ignite the dust or fumes.
c ) Keep children and bystanders away while operating
a power tool. Distractions can cause you to lose control.
2) Electrical safety
a ) Power tool plugs must match the outlet. Never
modify the plug in any way. Do not use any adapter
plugs with earthed (grounded) power tools.
Unmodified plugs and matching outlets will reduce risk of
electric shock.
b ) Avoid body contact with earthed or grounded
surfaces such as pipes, radiators, ranges and
refrigerators. There is an increased risk of electric shock if
your body is earthed or grounded.
c ) Do not expose power tools to rain or wet conditions.
Water entering a power tool will increase the risk of
electric shock.
d ) Do not abuse the cord. Never use the cord for
carrying, pulling or unplugging the power tool. Keep
cord away from heat, oil, sharp edges or moving
parts. Damaged or entangled cords increase the risk of
electric shock.
e ) When operating a power tool outdoors, use an
extension cord suitable for outdoor use. Use of a cord
suitable for outdoor use reduces the risk of electric shock.
f ) If operating a power tool in a damp location is
unavoidable, use a 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
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.
b )
c )
d )
e )
f )
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.
g )
h )
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.
i )
Safety Instructions for All Operations
a ) This power tool is intended to function as a
grinder, sander, wire brush or cut-off tool. Read
j )
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.
Operations such as polishing 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.
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.
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.
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.
Threaded mounting of accessories must match the
grinder spindle thread. For accessories mounted by
flanges, the arbour hole of the accessory must fit the
locating diameter of the flange. Accessories that do
not match the mounting hardware of the power tool will
run out of balance, vibrate excessively and may cause loss
of control.
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.
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
by your operation. Prolonged exposure to high intensity
noise may cause hearing loss.
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.
Hold power tool by insulated gripping surfaces only,
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 electrical shock.
k ) Position the cord clear of the spinning accessory. If
you lose control, the cord may be cut or snagged and your
hand or arm may be pulled into the spinning accessory.
l ) 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.
m ) 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.
n ) 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.
o ) Do not operate the power tool near flammable
materials. Sparks could ignite these materials.
p ) Do not use accessories that require liquid coolants.
Using water or other liquid coolants may result in
electrocution or shock.
q ) Do not use Type 11 (flaring cup) wheels on this tool.
Using inappropriate accessories can result in injury.
r ) Always use side handle. Tighten the handle securely.
The side handle should always be used to maintain control
of the tool at all times.
WARNING: We recommend the use of a residual current
device with a residual current rating of 30mA or less.
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
in turn causes the uncontrolled power tool to be forced in the
direction opposite of the accessory’s rotation at the point of the
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 power 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
b )
c )
d )
e )
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.
Never place your hand near the rotating accessory.
Accessory may kickback over your hand.
Do not position your body in the area where power
tool will move if kickback occurs. Kickback will propel
the tool in direction opposite to the wheel’s movement at
the point of snagging.
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.
Do not attach a saw chain woodcarving blade or
toothed saw blade. Such blades create frequent kickback
and loss of control.
Safety Warnings Specific for Grinding and
Abrasive Cutting-Off Operations
a ) Use only wheel types that are recommended for your
power tool and the specific guard designed for the
selected wheel. Wheels for which the power tool was not
designed cannot be adequately guarded and are unsafe.
b ) The grinding surface of centre depressed wheels
must be mounted below the plane of the guard lip.
An improperly mounted wheel that projects through the
plane of the guard lip cannot be adequately protected.
c ) The guard must be securely attached to the power
tool and positioned for maximum safety, so the least
amount of wheel is exposed towards the operator.
The guard helps to protect the operator from broken wheel
fragments and accidental contact with wheel and sparks
that could ignite clothing.
d ) Wheels must be used only for recommended
applications. For example: do not grind with the side
of cut-off wheel. Abrasive cut-off wheels are intended
for peripheral grinding, side forces applied to these wheels
may cause them to shatter.
e ) Always use undamaged wheel flanges that are
of correct size and shape for your selected wheel.
Proper wheel flanges support the wheel thus reducing the
possibility of wheel breakage. Flanges for cut-off wheels
may be different from grinding wheel flanges.
f ) Do not use worn down wheels from larger power
tools. Wheel intended for larger power tool is not suitable
for the higher speed of a smaller tool and may burst.
Additional Safety Warnings Specific for
Abrasive Cutting-Off Operations
a ) Do not “jam” the cut-off wheel or apply excessive
pressure. Do not attempt to make an excessive depth
of cut. Overstressing the wheel increases the loading and
b )
c )
d )
e )
f )
susceptibility to twisting or binding of the wheel in the cut
and the possibility of kickback or wheel breakage.
Do not position your body in line with and behind
the rotating wheel. When the wheel, at the point of
operations, is moving away from your body, the possible
kickback may propel the spinning wheel and the power
tool directly at you.
When wheel is binding 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 cutoff 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 binding.
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
minimise 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 cut and near 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.
Safety Warnings Specific for Sanding
a ) Do not use excessively oversized sanding disc
paper. Follow manufacturer’s recommendations,
when selecting sanding paper. Larger sanding paper
extending beyond the sanding pad presents a laceration
hazard and may cause snagging, tearing of the disc
or kickback.
Safety Warnings Specific for Wire Brushing
a ) Be aware that wire bristles are thrown by the brush
even during ordinary operation. Do not overstress
the wires by applying excessive load to the brush.
The wire bristles can easily penetrate light clothing and/
or skin.
b ) If the use of a guard is recommended for wire
brushing, do not allow any interference of the
wire wheel or brush with the guard. Wire wheel
or brush may expand in diameter due to work and
centrifugal forces.
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.
Risk of dust from hazardous substances.
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.
Mains Plug Replacement
(U.K. & Ireland Only)
If a new mains plug needs to be fitted:
• Safely dispose of the old plug.
• Connect the brown lead to the live terminal in the plug.
• Connect the blue lead to the neutral terminal.
WARNING: No connection is to be made to the
earth terminal.
Follow the fitting instructions supplied with good quality plugs.

Charge Indicators
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.

CAUTION: Use extra care when working over an edge, as
a sudden sharp movement of grinder may be experienced.
Precautions To Take When Working on a
Painted Workpiece
1. Sanding or wire brushing of lead based paint is NOT
RECOMMENDED due to the difficulty of controlling the
contaminated dust. The greatest danger of lead poisoning is
to children and pregnant women.
2. Since it is difficult to identify whether or not a paint contains
lead without a chemical analysis, we recommend the
following precautions when sanding any paint:
Personal Safety
1. No children or pregnant women should enter the work area
where the paint sanding or wire brushing is being done
until all clean up is completed.
2. A dust mask or respirator should be worn by all persons
entering the work area. The filter should be replaced daily or
whenever the wearer has difficulty breathing.
NOTE: Only those dust masks suitable for working with lead
paint dust and fumes should be used. Ordinary painting
masks do not offer this protection. See your local hardware
dealer for the proper N.I.O.S.H. approved mask.
3. NO EATING, DRINKING or SMOKING should be done in the
work area to prevent ingesting contaminated paint particles.
Workers should wash and clean up BEFORE eating, drinking
or smoking. Articles of food, drink, or smoking should not be
left in the work area where dust would settle on them.
Environmental Safety
1. Paint should be removed in such a manner as to minimize
the amount of dust generated.
2. Areas where paint removal is occurring should be sealed
with plastic sheeting of 4 mils thickness.
3. Sanding should be done in a manner to reduce tracking of
paint dust outside the work area.
Cleaning and Disposal
1. All surfaces in the work area should be vacuumed and
thoroughly cleaned daily for the duration of the sanding
project. Vacuum filter bags should be changed frequently.
2. Plastic drop cloths should be gathered up and disposed
of along with any dust chips or other removal debris. They
should be placed in sealed refuse receptacles and disposed
of through regular trash pick-up procedures.
During clean up, children and pregnant women should be
kept away from the immediate work area.
3. All toys, washable furniture and utensils used by children
should be washed thoroughly before being used again.
Edge Grinding and Cutting (Fig. J)
WARNING: Do not use edge grinding/cutting wheels for
surface grinding applications because these wheels are
not designed for side pressures encountered with surface
grinding. Wheel breakage and injury may result.
CAUTION: Wheels used for edge grinding and cutting
may break or kick back if they bend or twist while the tool
is being used. In all edge grinding/cutting operations, the
open side of the guard must be positioned away from
the operator.
NOTICE: Edge grinding/cutting with a Type 27 wheel
must be limited to shallow cutting and notching—less
than 13 mm in depth when the wheel is new. Reduce the
depth of cutting/notching equal to the reduction of the
wheel radius as it wears down. Refer to the Accessories
Chart for more information. Edge grinding/cutting with a
Type 1 wheel requires usage of a Type 1 guard.
1. Allow the tool to reach full speed before touching the tool
to the work surface.
2. Apply minimum pressure to the work surface, allowing
the tool to operate at high speed. Grinding/cutting rate is
greatest when the tool operates at high speed.
3. Position yourself so that the open-underside of the wheel is
facing away from you.
4. Once a cut is begun and a notch is established in the
workpiece, do not change the angle of the cut. Changing
the angle will cause the wheel to bend and may cause
wheel breakage. Edge grinding wheels are not designed to
withstand side pressures caused by bending.
5. Remove the tool from the work surface before turning
the tool off. Allow the tool to stop rotating before laying
it down.
Metal Applications
When using the tool in metal applications, make sure that a
residual current device (RCD) has been inserted to avoid residual
risks caused by metal swarf.
If the power supply is shut off by the RCD, take the tool to an
authorised DeWALT repair agent.
WARNING: In extreme working conditions, conductive
dust can accumulate inside the machine housing when
working with metal. This can result in the protective
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. Refer
to Maintenance.
Cutting Metal
For cutting with bonded abrasives, always use the
guard type 1.
When cutting, work with moderate feed, adapted to the
material being cut. Do not exert pressure onto the cutting disc,
tilt or oscillate the machine.
Do not reduce the speed of running down cutting discs by
applying sideward pressure.
The machine must always work in an upgrinding motion.
Otherwise, the danger exists of it being pushed uncontrolled
out of the cut.
When cutting profiles and square bar, it is best to start at the
smallest cross section.
Rough Grinding
WARNING: Blow dirt and dust out of the main housing
with dry air as often as dirt is seen collecting in and around
the air vents. Wear approved eye protection and approved
dust mask when performing this procedure.
WARNING: Never use solvents or other harsh chemicals
for cleaning the non-metallic parts of the tool. These
chemicals may weaken the materials used in these parts.
Use a cloth dampened only with water and mild soap.
Never let any liquid get inside the tool; never immerse any
part of the tool into a liquid.
Optional Accessories
Never use a cutting disc for roughing.
Always use the guard type 27.
The best roughing results are achieved when setting the
machine at an angle of 30° to 40°. 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: Since accessories, other than those offered
by DeWALT, have not been tested with this product, use
of such accessories with this tool could be hazardous.
To reduce the risk of injury, only DeWALT recommended
accessories should be used with this product.
Consult your dealer for further information on the
appropriate accessories.
Cutting Stone
Protecting the Environment
The machine shall be used only for dry cutting.
For cutting stone, it is best to use a diamond cutting disc.
Operate the machine only with additional dust protection mask.
