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.

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.

4

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 Instructions for All Operations

a ) This power tool is intended to function as a

grinder, sander, wire brush or cut-off tool. Read

ENGLISH

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 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.

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 ) 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.

g ) 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.

h ) 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.

i ) 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.

j ) Hold the power tool by insulated gripping surfaces

only, when performing an operation where the

5

ENGLISH

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.

k ) 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.

l ) 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.

m ) 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.

n ) Do not operate the power tool near flammable

materials. Sparks could ignite thesematerials.

o ) 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
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 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
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 ) Never place your hand near the rotating accessory.

Accessory may kickback over yourhand.

c ) 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.

d ) 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.

e ) 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

susceptibility to twisting or binding of the wheel in the cut
and the possibility of kickback or wheelbreakage.

b ) 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.

c ) 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

6

a complete stop. Never attempt to remove the cut-

DeWALT

DeWALT

DeWALT

DeWALT

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binding.

d ) 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.

e ) 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.

f ) 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
Operations

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
Operations

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.

Additional Safety Rules for Grinders

a ) Do not use Type 11 (flaring cup) wheels on this tool.

Using inappropriate accessories can result ininjury.

b ) Always use side handle. Tighten the handle securely.

The side handle should always be used to maintain control
of the tool at alltimes.

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.

ENGLISH

• Risk of personal injury due to prolongeduse.

• Risk of dust from hazardoussubstances.

Electrical Safety

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.

Features

Kickback Brake™

When a pinch, stall, or bind-up event is sensed, the electronic
brake engages with maximum force to quickly stop the wheel,
reduce the movement of the grinder, and shut the grinder
off. The switch will need to be released then depressed to
restarttool.

Power-OFF™ Overload Protection

The power supply to the motor will be reduced in case of
motor overload. With continued motor overload, the tool will
shut off. The switch will need to be released then depressed
to restarttool. The tool will power off each time the current
load reaches the overload current value (motor burn-up point).
If continued overload shutdowns occur, apply less force/
weight on the tool until the tool will function without the
overloadengaging.

Anti-vibration Side Handle

The anti-vibration side handle offers added comfort by
absorbing the vibrations caused by thetool.

Soft Start Feature

The soft start feature allows a slow speed build-up to avoid an
initial jerk when starting. This feature is particularly useful when
working in confinedspaces.

No-Volt

The No-volt function stops the grinder restarting without the
switch being cycled if there is a break in the powersupply.

Electronic Clutch

The electronic torque limiting clutch reduces the maximum
torque reaction transmitted to the operator in case of jamming
of a disc. This feature also prevents the gearing and electric
motor from stalling. The torque limiting clutch has been factory­set and cannot beadjusted.

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 NIOSH-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

WARNING: Do not use edge grinding/cutting wheels for
surface grinding applications because these wheels are



ENGLISH

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 41 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.

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

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
