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.

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 mains-
operated (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

8
ENGLISH
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.
5) 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 (DWE4557 and DWE4597), wire brush, or
cut-off tool. 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 ) Operation such as polishing is not recommended to
be performed with this power tool.
Operation such as sanding (DWE4559; DWE4579;
DWE4579R and DWE4599) is 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 cannot be
adequately guarded or controlled.
f ) Threaded mounting of accessories must match the
grinder spindle thread. For accessories mounted by
flanges, the arbor 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

9
ENGLISH
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 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.
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 the 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, 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

10
ENGLISH
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
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 binding.
d ) Do not restart the cutting operation in the
workpiece. Let the wheel reach full speed and
carefully reenter 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
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 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
DWE4557, DWE4597 only
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 load and
centrifugalforces.
Additional Safety Rules for Grinders
• Do not use Type 11 (flaring cup) wheels on this tool.
Using inappropriate accessories can result in injury.
• 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.
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 power supply corresponds to the voltage
on the rating plate.
Your DEWALT tool is double insulated in accordance
with EN60745; therefore no earth wire is required.

in place.
• Secure and support the workpiece. 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 movement of the
workpiece and loss of control. Movement of the
workpiece or loss of control may create ahazard and
cause personal injury.
• 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 cut and near the edge of the
workpiece on both sides of the wheel.
• Always wear regular working gloves while operating
this tool.
• 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 to cool the
accessory. Do not touch accessories before they have
cooled. The discs become very hot during use.
• Never work with the grinding cup without asuitable
protection guard in place.
• Do not use the power tool with acut-off stand.
• Never use blotters together with bonded
abrasiveproducts.
• Be aware, the wheel continues to rotate after the tools
is switched off.
• The tool is not designed to be used with
agrindingcup.
• Do not use separate reducing bushings or adapters to
adapt large hole abrasive wheels.

To engage the lock, depress the spindle lock button and rotate
the spindle until you are unable to rotate the spindle further.
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
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 inthe 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
aprotection 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
will not become too hot, does not discolour and no grooves are
formed.
Cutting Stone
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.
Working Advice
Exercise caution when cutting slots in structural walls.
Slots in structural walls are subject to the country-specific
regulations. These regulations are to be observed under all
circumstances. Before beginning work, consult the responsible
structural engineer, architect or the construction supervisor.
Using Flap Discs
WARNING: Metal dust build-up. Extensive use of flap
discs in metal applications can result in the increased
potential for electric shock. To reduce this risk, insert an
RCD before use and clean the ventilation slots daily by
blowing dry compressed air into the ventilation slots
inaccordance with the below maintenance instructions.
MAINTENANCE
Your DEWALT power tool has been designed to operate

ПОПЕРЕДЖЕНЬ ТА ІНСТРУКЦІЙ
ДЛЯ ПОДАЛЬШОГО ВИКОРИСТАННЯ.
Термін "електричний інструмент" вусіх попередженнях
стосується використовуваних вами інструментів, що
працюють від мережі енергоспоживання (звикористанням
електричного кабелю) або акумуляторів (без кабелю).
1) Безпека робочої зони
a ) Дотримуйтесь чистоти та якісного
освітлення робочої зони. Невпорядковані
та неякісно освітлені робочі зони збільшують
імовірність нещасного випадку.
b ) Не використовуйте електричні інструменти
увибухонебезпечному середовищі, наприклад,
убезпосередній близькості до легкозаймистих
рідин, газів та ділянок знадмірним
пилоутворенням. Електричні інструменти
створюють іскри, що можуть спричинити займання
пилу чи легкозаймистих випарів.
c ) Тримайте дітей та сторонніх осіб на
відповідній віддалі під час використання
інструменту. Відвернення уваги може призвести до
втрати контролю.
2) Електрична безпека
a ) Тип вилки електричного інструменту має
відповідати типу розетки. Жодним чином не
модифікуйте тип вилки. Не використовуйте
адаптери із заземленими електричними
інструментами. Немодифіковані вилки та
відповідні розетки зменшують ризик ураження
електричним струмом.
b ) Уникайте контактів тіла ззаземленими
поверхнями, такими як труби, радіатори,
плити та холодильники. Якщо ваше тіло
заземлене, збільшується ризик ураження
електричним струмом.
c ) Не залишайте електричні інструменти під
дощем або вумовах підвищеної вологості. Вода,
що потрапляє велектричний інструмент, підвищує
ризик ураження електричним струмом.
d ) Не використовуйте кабель живлення не за
призначенням. Не використовуйте шнур для
переміщення, витягування та відключення від
розетки живлення електричного інструмента.
Тримайте шнур подалі від джерел високих
температур, мастил, гострих предметів та
рухомих деталей. Пошкоджені або перекручені

20
УКРАЇНСЬКА
шнури підвищують ризик ураження електричним
струмом.
e ) При експлуатації електричного інструменту
поза межами приміщення, використовуйте

призвести до серйозних травм.
b ) Використовуйте засоби особистої безпеки.
Завжди використовуйте засоби захисту
очей. Засоби безпеки, такі як протипилова маска,
неслизькі безпечні черевики, захисний шолом та
засоби захисту слуху, застосовані при відповідних
умовах, зменшують імовірність особистих травм.
c ) Уникайте випадкового запуску. Переконайтесь
втому, що вимикач знаходиться впозиції
Вимк. перед підключенням до джерела
живлення та/або акумулятора, переміщенням
або перенесенням пристрою. Переміщення
інструменту, тримаючи палець на вимикачі, або
підключення живлення зперемикачем впозиції Увімк.,
може призвести до нещасного випадку.
d ) Перед вмиканням електроінструменту зніміть
зпристрою всі регулювальні або гайкові ключі.
Гайковий ключ, що залишився прикріпленим до
будь-якої деталі електричного пристрою, що
обертається, може призвести до травмування.
e ) Не перенапружуйтесь. Дотримуйтесь
правильного положення ніг та рівноваги.
Це дасть вам змогу контролювати роботу
інструменту внепередбачуваних ситуаціях.
f ) Одягайте відповідний одяг. Не одягайте вільний
одяг чи прикраси. Тримайте ваше волосся, одяг
та рукавиці подалі від рухомих деталей. Вільний
одяг, прикраси або довге волосся можуть зачепитися
за рухомі деталі.
g ) Якщо передбачені пристрої для підключення
до засобів виділення та збору пилу,
переконайтеся, що вони правильно підключені
та використовуються за призначенням.
Використання таких пристроїв зменшує ризик
виникнення небезпечних ситуацій, що пов’язані
зпотраплянням пилу.
4) Вимоги щодо експлуатації
електричного інструменту та догляду
за ним
