Part 2-13: Particular requirements for chain saws



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.

This consolidated version of IEC 60745-2-13 consists of the second edition (2006)
[documents 61F/625/FDIS and 61F/637/RVD] and its amendment 1 (2009) [documents
116/17/FDIS and 116/18/RVD]. It bears the edition number 2.1.
The technical content is therefore identical to the base edition and its amendment and
has been prepared for user convenience. A vertical line in the margin shows where the
base publication has been modified by amendment 1. Additions and deletions are
displayed in red, with deletions being struck through.

8.12.1.1 Addition:
Chain saw safety warnings:
• Keep all parts of the body away from the saw chain when the chain saw is operating.
Before you start the chain saw, make sure the saw chain is not contacting anything.
A moment of inattention while operating chain saws may cause entanglement of your
clothing or body with the saw chain.
• Always hold the chain saw with your right hand on the rear handle and your left
hand on the front handle. Holding the chain saw with a reversed hand configuration
increases the risk of personal injury and should never be done.
NOTE For chain saws designed with the guide bar on the left side, the reference to “right hand” and “left
hand” positioning is reversed.
• Hold the power tool by insulated gripping surfaces only, because the saw chain may
contact hidden wiring or its own cord. Saw chains contacting a "live" wire may make
exposed metal parts of the power tool "live" and could give the operator an electric shock.
• Wear safety glasses and hearing protection. Further protective equipment for head,
hands, legs and feet is recommended. Adequate protective clothing will reduce
personal injury by flying debris or accidental contact with the saw chain.
• Do not operate a chain saw in a tree. Operation of a chain saw while up in a tree may
result in personal injury.
• Always keep proper footing and operate the chain saw only when standing on fixed,
secure and level surface. Slippery or unstable surfaces such as ladders may cause a
loss of balance or control of the chain saw.
• When cutting a limb that is under tension be alert for spring back. When the tension
in the wood fibres is released the spring loaded limb may strike the op
