Safety instructions
General power tool safety warnings
Warning! Read all safety
warnings and all instructions.
Failure to follow the warnings and
instructions listed below may
result in electric shock, fire and/or
serious injury.
Save all warnings and instructions for
future reference.
The term “power tool” in all of the warnings
listed below 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 o-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.

ENGLISH
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 o. 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 aect the power
tools 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 dierent from those intended
could result in a hazardous situation.

Additional power tool safety
warnings
Warning! Additional safety
warnings for grinding, sanding, wire
brushing, polishing or abrasive
cutting-o operations
• This power tool is intended to function
as a grinder, sander, wire brush, polisher
or cut-o 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.
• 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 cannot be
adequately guarded or controlled.
5
ENGLISH
(Original instructions)
• 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.
• Do not use a damaged accessory.
Before each use inspect the accessory
such as abrasive wheels 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 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 filtering 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 shock
the operator.
• 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.
• 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.
• 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.
• 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.
• Do not operate the power tool near
flammable materials. Sparks could ignite
these materials.
• Do not use accessories that require
liquid coolants. Using water or other
liquid coolants may result in electrocution
or shock.
Note: The above warning does not apply for
power tools specifically designed for use
with a liquid system.
Kickback and related warnings
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.
6
(Original instructions)
ENGLISH
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.
• 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 reactions 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-o
operations
• 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.
• 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.
• 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 operator from
broken wheel fragments and accidental
contact with wheel.
• Wheels must be used only for
recommended applications. For
example: do not grind with the side of
cut-o wheel. Abrasive cut-o wheels
are intended for peripheral grinding, side
forces applied to these wheels may cause
them to shatter.
• 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-o wheels may be dierent from
grinding wheel flanges.
• 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-o operations
• Do not "jam" the cut-off wheel or apply
excessive pressure. Do not attempt to
make an excessive depth of cut. Over
stressing 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.
• Do not position your body in line with
and behind the rotating wheel. When the
wheel, at the point of operation, 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
o the power tool and hold the power
tool motionless until the wheel comes to
a complete stop. Never attempt to
remove the cut-o 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.
7
ENGLISH
(Original instructions)
• 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 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 operations
• Do not use excessively oversized
sanding disc paper. Follow
manufacturers 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
polishing operations
• Do not allow any loose portion of the
polishing bonnet or its attachment
strings to spin freely. Tuck away or trim
any loose attachment strings. Loose and
spinning attachment strings can entangle
your fingers or snag on the workpiece.
Safety of others
• This appliance is not intended for use by
persons (including children) with
reduced physical, sensory or mental
capabilities, or lack of experience and
knowledge, unless they have been given
supervision or instruction concerning use
of the appliance by a person responsible
for their safety.
• Children should be supervised to ensure
that they do not play with the appliance.
Residual risks.
Additional residual risks may arise when
using the tool which may not be included in
the enclosed safety warnings. These risks
can arise from misuse, prolonged use etc.
Even with the application of the relevant
safety regulations and the implementation of
safety devices, certain residual risks can not
be avoided. These include:
• Injuries caused by touching any
rotating/ moving parts.
• Injuries caused when changing any parts,
blades or accessories.
• Injuries caused by prolonged use of a
tool. When using any tool for prolonged
periods ensure you take regular breaks.
• Impairment of hearing.
• Health hazards caused by breathing dust
developed when using your tool
(example:- working with wood,
especially oak, beech and MDF.)
Vibration
The declared vibration emission values
stated in the technical data and the
declaration of conformity have been
measured in accordance with a standard test
method provided by EN 60745 and may be
used for comparing one tool with another.
The declared vibration emission value may
also be used in a preliminary assessment of
exposure.
Warning! The vibration emission value during
actual use of the power tool can dier from
the declared value depending on the ways in
which the tool is used. The vibration level
may increase above the level stated.
When assessing vibration exposure to
determine safety measures required by
2002/44/EC to protect persons regularly
using power tools in employment, an
estimation of vibration exposure should
consider, the actual conditions of use and
the way the tool is used, including taking
account of all parts of the operating cycle
such as the times when the tool is switched
o and when it is running idle in addition to
the trigger time.

ENGLISH
(Original instructions)
When grinding, always maintain the correct
angle between the disc and the work
surface (15°)(Fig. D). This increases the
removal capacity of the disc and avoids
unnecessary overloading.
Overload
Overloading will cause damage to the
motor of your angle grinder. This can
happen if your angle grinder is subjected to
heavy duty use for prolonged periods of
use. Do not in any circumstances, attempt
to exert too much pressure on your angle
grinder to speed up your work. The abrasive
discs operate more eciently when a light
pressure is exerted, thus avoiding a drop in
the speed of your angle grinder.
Maintenance
Keep guards, air vents and the motor
housing as clear as possible of dust and dirt.
Wipe with a clean cloth and blow through
with a low-pressure air supply. Excessive
build-up of metal dust can cause tracking of
electrical current from the internal parts to
exposed metal parts. Do not overload your
angle grinder. Overloading causes a
reduction in speed and eciency, causing
your angle grinder to become too hot. If this
happens, operate your angle grinder under
no load for one or two minutes until it has
cooled to normal operating temperature.
Switching your angle grinder o under load
will reduce the life of the switch.

электрическим инструментом.
Внимание! Внимательно прочитайте все
предупреждающие надписи и указания по
безопасной работе. Несоблюдение предупреждающих
надписей и указаний по безопасной работе может
привести к поражению электрическим током, пожару
и/или серьезным травмам персонала.
Храните все предупреждающие надписи и указания
по безопасной работе для использования в
будущем.
Термин «электрический инструмент», используемый во
всех предупреждающих надписях и указаниях по
технике безопасности, представленных ниже,
относится к электрическому инструменту,
работающему от сети (со шнуром электропитания) или
от аккумуляторной батареи (без шнура питания).
1. Указания по безопасности на рабочем месте
a. Рабочее место должно содержаться в чистоте и
должно быть оборудовано надлежащим
освещением. Беспорядок или плохое освещение
на рабочем месте может привести к несчастному
случаю.
b. Запрещается использование электрического
инструмента во взрывоопасной среде,
например, в условиях наличия
легковоспламеняющихся жидкостей, газов или
пыли. Искры, возникающие при работе
электрического инструмента, могут воспламенить
пыль, пары и газы.
c. Запрещается нахождение детей и посторонних
лиц вблизи работающего электрического
инструмента. Отвлекающие факторы могут
привести к потере контроля за работой
инструмента.
2. Электрическая безопасность
a. Вилка шнура электрического инструмента
должна соответствовать сетевой розетке.
Запрещается вносить какие-либо изменения в
вилку электрического шнура. Запрещается
использование каких-либо штепсельных
переходников при работе заземленного
электрического инструмента. Отсутствие
изменений в вилках электрических шнуров и
соответствие электрических вилок и розеток
снижает риск поражения электрическим током.
b. Не допускайте контакта тела с заземленными
поверхностями таких объектов, как трубы,
радиаторы, электроплиты и холодильники. Если
ваше тело заземлено, риск его поражения
электрическим током повышается.
c. Электрические инструменты не должны
подвергаться воздействию дождя и находится в
условиях повышенной влажности. При попадании
влаги внутрь электрического инструмента
повышается риск поражения электрическим током.
d. Запрещается использовать электрический шнур
не по назначению. Никогда не берите, не тяните
и не вынимайте электрический инструмент за
шнур. Электрический шнур не должен
находиться вблизи источников тепла, масла,
острых краев и движущихся деталей.
Поврежденные и закрученные электрические
шнуры повышают риск поражения электрическим
током.
e. При работе электрического инструмента на
открытом воздухе используйте
соответствующий удлинитель. Использование
удлинителя, предназначенного для работы на
открытом воздухе, снижает риск поражения
электрическим током.
f. Если работы с помощью электрического
инструмента внутри влажного помещения
должны быть выполнены обязательно, в таком
случае необходимо использовать устройство
защитного отключения (УЗО) электрической
сети. Использование УЗО снижает риск поражения
электрическим током. Примечание: Термин
«устройство защитного отключения (УЗО)» может
быть заменен термином «выключатель короткого
замыкания на землю (ВКЗЗ)» или термином
«автоматический выключатель утечки на землю
(АВУЗ)».
