The vibration and/or noise emission level given in this
information sheet has been measured in accordance with
a standardised test given in EN62841 and may be used to
compare one tool with another. It may be used for a preliminary
assessment ofexposure.
WARNING: The declared vibration and/or noise 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 and/or
noise emission may differ. This may significantly increase
the exposure level over the total workingperiod.
An estimation of the level of exposure to vibration and/
or noise 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.

ENGLISH
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

shock, fire and/or seriousinjury.
performed. Use of the power tool for operations different
from those intended could result in a hazardoussituation.
h ) Keep handles and grasping surfaces dry, clean and
free from oil and grease. Slippery handles and grasping
surfaces do not allow for safe handling and control of the
tool in unexpectedsituations.
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.
e ) Do not use a battery pack or tool that is damaged or
modified. Damaged or modified batteries may exhibit
unpredictable behaviour resulting in fire, explosion or risk
ofinjury.
f ) Do not expose a battery pack or tool to fire or
excessive temperature. Exposure to fire or temperature
above 130°C may causeexplosion.
g ) Follow all charging instructions and do not charge
the battery pack or tool outside the temperature
range specified in the instructions. Charging
improperly or at temperatures outside the specified range
may damage the battery and increase the risk offire.
6) Service

person using only identical replacement parts. This
will ensure that the safety of the power tool ismaintained.
b ) Never service damaged battery packs. Service
of battery packs should only be performed by the
manufacturer or authorized serviceproviders.
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 and clothing 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.
h ) Do not let familiarity gained from frequent use of
tools allow you to become complacent and ignore
tool safety principles. A careless action can cause severe
injury within a fraction of asecond.
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 remove the battery pack, if detachable, 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 and accessories. 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

metal parts of the power tool "live" and could give the
operator an electricalshock.
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
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.
Kickback is the result of tool misuse and/or incorrect operating
procedures or conditions and can be avoided by taking proper
precautions as given below:
a ) Maintain a firm grip with both hands on the power
tool and position your body and arms 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
b ) Operations such as polishing, sanding or hole
cutting are not 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 convert this power tool to operate in a way
which is not specifically designed and specified by
the tool manufacturer. Such a conversion may result in
a loss of control and cause serious personal injury
d ) Do not use accessories which are not specifically
designed and specified by the tool manufacturer.
Just because the accessory can be attached to your power
tool, it does not assure safeoperation.
e ) 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.
f ) 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.
g ) The dimensions of the accessory mounting must fit
the dimensions of the mounting hardware of the
power tool. 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.
h ) 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, position
yourself and bystanders away from the plane of
the rotating accessory and run the power tool at
maximum no‑load speed for one minute. Damaged
accessories will normally break apart during this testtime.
i ) Wear personal protective equipment. Depending on
application, use face shield, safety goggles or safety
glasses. As appropriate, wear dust mask, hearing
protectors, gloves and workshop apron capable of
stopping small abrasive or workpiece fragments.
The eye protection must be capable of stopping flying
debris generated by various operations. The dust mask or
respirator must be capable of filtrating particles generated
by the particular operation. Prolonged exposure to high
intensity noise may cause hearingloss.
j ) Keep bystanders a safe distance away from work
area. Anyone entering the work area must wear
personal protective equipment. Fragments of
workpiece or of a broken accessory may fly away and
cause injury beyond immediate area ofoperation.
k ) Hold the power tool by insulated gripping surfaces
only, when performing an operation where the
cutting accessory may contact hidden wiring. Cutting
accessory contacting a "live" wire may make exposed

ENGLISH
c ) When wheel is binding or when interrupting a cut
for any reason, switch off the power tool and hold it
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 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
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.
g ) Do not attempt to do curved cutting.
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, which can lead to seriousinjury.
Additional Safety Instructions for
SandingOperations
a ) Use proper sized sanding disk paper. Follow
manufacturers recommendations, when selecting
sanding paper. Larger sanding paper extending too far
beyond the sanding pad presents a laceration hazard and
may cause snagging, tearing of the disc or kickback.
Additional Safety Instructions 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 specified 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.
c ) When using segmented diamond wheels, use
only diamond wheels with a peripheral gap not
greater than 10mm and negative rakeangle.
(refer to Additional Information for Guards and
Accessorieschart).
snag the rotating accessory and cause loss of control
orkickback.
e ) Do not attach a saw chain woodcarving blade,
segmented diamond wheel with a peripheral gap
greater than 10mm or toothed sawblade.Such
blades create frequent kickback and loss ofcontrol.
Safety Warnings Specific for Grinding and
Cutting-Off Operations
a ) Use only wheel types that are specified 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, accidental contact with wheel and sparks that
could igniteclothing.
d ) Wheels must be used only for specified 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. A wheel intended for larger power tool is not
suitable for the higher speed of a smaller tool and
mayburst.
g ) When using dual purpose wheels always use the
correct guard for the application being performed.
Failure to use the correct guard may not provide
the desired level of guarding, which could lead to
seriousinjury.
Additional Safety Warnings Specific for
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.
