Part 3-10: Particular requirements for transportable cut-off machines
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.

International Standard IEC 62841-3-10 has been prepared by IEC technical committee 116:

Safety of motor-operated electric tools.
The text of this standard is based on the following documents:

8.14.1.101 Safety instructions for cut-off machines
1) Cut-off machine safety warnings

a) Position yourself and bystanders away from the plane of the rotating wheel. The

guard helps to protect the operator from broken wheel fragments and accidental
contact with wheel.

b) Use only bonded reinforced or diamond cut-off wheels for your power tool. Just

because an accessory can be attached to your power tool, it does not assure safe
operation.

NOTE 1 The wording “bonded reinforced” or “diamond” is used as applicable depending on the

designation of the tool.
c) 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.
d) Wheels must be used 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.

e) Always use undamaged wheel flanges that are of correct diameter for your

selected wheel. Proper wheel flanges support the wheel thus reducing the possibility

of wheel breakage.
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 arbour size of wheels and flanges must properly fit the spindle of the power

tool. Wheels and flanges 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.
