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.
Identify additional safety measures to protect the operator
from the effects of vibration and/or noise such as: maintain
the tool and the accessories, keep the hands warm
(relevant for vibration), organisation of workpatterns.

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

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
performed. Use of the power tool for operations different
from those intended could result in a hazardoussituation.
GENERAL POWER TOOL SAFETY WARNINGS
WARNING: 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.
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 a dust mask,
non-skid safety shoes, hard hat or hearing protection used
for appropriate conditions will reduce personalinjuries.

ADDITIONAL SPECIFIC SAFETY RULES
Safety Warnings Common for Grinding
a ) This power tool is intended to function as a grinder.
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 ) Operations such as sanding, wire brushing, polishing
and cutting-off 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 ) 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.
g ) Mandrel mounted wheels or other accessories must
be fully inserted into the collet or chuck. If the mandrel
is insufficiently held and/or the overhang of the wheel is
too long, the mounted wheel may become loose and be
ejected at highvelocity.
h ) 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
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) 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.
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 your 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 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.
l ) Always hold the tool firmly in your hand(s) during
start up. The reaction torque of the motor, as it
accelerates to full speed, can cause the tool totwist.
m ) Use clamps to support workpiece whenever
practical. Never hold a small workpiece in one hand
and the tool in the other while in use. Clamping a
small workpiece allows you to use your hand(s) to control
the tool. Round material such as dowel rods, pipes or
tubing have a tendency to roll while being cut, and may
cause the bit to bind or jump towardyou.
n ) 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.
o ) After changing bits or making any adjustments,
make sure the collet nut, chuck or any other
adjustment devices are securely tightened. Loose
adjustment devices can unexpectedly shift, causing
loss of control, loose rotation components will be
violentlythrown.
p ) 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.
q ) 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.
r ) Do not operate the power tool near flammable
materials. Sparks could ignite thesematerials.
s ) Do not use accessories that require liquid coolants.
Using water or other liquid coolants may result in
electrocution orshock.

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.
SAVE THESE INSTRUCTIONS
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 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 ) 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.
c ) Do not attach a saw chain woodcarving blade or
toothed saw blade. Such blades create frequent kickback
and loss ofcontrol.
d ) Always feed the bit into the material in the same
direction as the cutting edge is exiting from the
material (which is the same direction as the chips are
thrown). Feeding the tool in the wrong direction causes
the cutting edge of the bit to climb out of the work and
pull the tool in the direction of thisfeed.
e ) When using rotary files, cut off wheels, high-speed
cutters or tungsten carbide cutters, always have the
work securely clamped. These wheels will grab if they
become slightly canted in the groove, and can kickback.
When a cut-off wheel grabs, the wheel itself usually
breaks. When a rotary file, high speed cutter or tungsten
carbide cutter grabs, it may jump from the groove and you
could lose control of thetool.
Safety Warnings Specific for Grinding and
Cutting-Off Operations
a ) Use only wheel types that are recommended for your
power tool and only for recommended applications.
For example: Do not grind with the side of a cut-off
wheel. Abrasive cut-off wheels are intended for peripheral
grinding, side forces applied to these wheels may cause
them toshatter.
b ) For threaded abrasive cones and plugs use only
undamaged wheel mandrels with an unrelieved
shoulder flange that are of a correct size and length.
Proper mandrels will reduce the possibility ofbreakage.
c ) Do not "jam" a 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 snapping of the wheel in the
cut and the possibility of kickback ort wheelbreakage.
d ) Do not position your hand in line with or behind
a rotating wheel. When the wheel, at the point of
operation, is moving away from your hand, the possible
kickback may propel the wheel and the power tool directly
atyou.
e ) When wheel is pinched, snagged 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 pinching orsnagging.
f ) 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.
g ) 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 the cut and the edge of the workpiece on both sides of
thewheel.
h ) 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.
