FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.

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) 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) 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.
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 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.
NOTE The above warning may be omitted if polishing is the only recommended operation.
Hold the 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 electric shock.
NOTE The above warning may be omitted if polishing or sanding are the only recommended operations.
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.
NOTE The above warning does not apply for power tools specifically designed for use with a liquid system.

8.12.1.102 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 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 reactions 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.
8.12.1.103 Additional safety instructions for grinding and cutting-off operations
NOTE If grinding and cut-off operations are not recommended by the manufacturer, this section may be omitted.
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 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.
NOTE The above warning may be omitted for die grinders and grinders or cut-off grinders with rated capacity
of less than 55mm.
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.
NOTE The above warning may be omitted for grinders or cut-off grinders with a rated capacity of less than
55 mm.
c) 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.
d) 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.

– 14 – 60745-2-3  IEC:2006+A1:2010
e) 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.
8.12.1.104 Additional safety instructions for cutting-off operations
NOTE If cutting-off operation is not recommended by the manufacturer, this section may be omitted.
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 operation, 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.
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.
8.12.1.105 Additional safety instructions for sanding operations
NOTE If sanding operation is not recommended by the manufacturer, this section may be omitted.
Safety Warnings Specific for Sanding Operations:
a) 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.
8.12.1.106 Additional safety instructions for polishing operations
NOTE If polishing operation is not recommended by the manufacturer, this section may be omitted.
Safety Warnings Specific for Polishing Operations:
a) 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.
8.12.1.107 Additional safety instructions for wire brushing operations
NOTE If wire brushing operation is not recommended by the manufacturer, this section may be omitted.

60745-2-3  IEC:2006+A1:2010 – 15 –
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.
