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) IEC draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). IEC takes no position concerning the evidence, validity or applicability of any claimed patent rights in
respect thereof. As of the date of publication of this document, IEC had not received notice of (a) patent(s),
which may be required to implement this document. However, implementers are cautioned that this may not
represent the latest information, which may be obtained from the patent database available at
https://patents.iec.ch. IEC shall not be held responsible for identifying any or all such patent rights.

Part 3-11: Particular requirements for transportable
combined mitre and bench 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) IEC draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). IEC takes no position concerning the evidence, validity or applicability of any claimed patent rights in
respect thereof. As of the date of publication of this document, IEC had not received notice of (a) patent(s), which
may be required to implement this document. However, implementers are cautioned that this may not represent
the latest information, which may be obtained from the patent database available at https://patents.iec.ch. IEC
shall not be held responsible for identifying any or all such patent rights.
IEC 62841-3-11 has been prepared by IEC technical committee 116: Safety of motor-operated
electric tools. It is an International Standard.
The text of this International Standard is based on the following documents:
Draft Report on voting
116/802/FDIS 116/824/RVD

the above table.
The language used for the development of this International Standard is English.
This document is to be used in conjunction with IEC 62841-1:2014.
This document supplements or modifies the corresponding clauses in IEC 62841-1, so as to
convert it into the IEC Standard: Particular requirements for transportable combined mitre and
bench saws.
Where a particular subclause of IEC 62841-1 is not mentioned in this document, that subclause
applies as far as reasonable. Where this document states "addition", "modification" or
"replacement", the relevant text in IEC 62841-1 is to be adapted accordingly.
The following print types are used:
– requirements: in roman type;
– test specifications: in italic type;
– terms defined in Clause 3: in bold type
– notes: in small roman type.
Subclauses, notes, tables and figures which are additional to those in IEC 62841-1 are
numbered starting from 101.
Subclauses, notes, tables and figures in Annex K and Annex L which are additional to those in
the main body of this document are numbered starting from 301.
A list of all parts in the IEC 62841 series, published under the general title: Electric motor-
operated hand-held tools, transportable tools and lawn and garden machinery – Safety, can be
found on the IEC website.
This document was drafted in accordance with ISO/IEC Directives, Part 2, and developed in
accordance with ISO/IEC Directives, Part 1 and ISO/IEC Directives, IEC Supplement, available
at www.iec.ch/members_experts/refdocs. The main document types developed by IEC are
described in greater detail at www.iec.ch/standardsdev/publications.
The committee has decided that the contents of this document will remain unchanged until the
stability date indicated on the IEC website under webstore.iec.ch in the data related to the
specific document. At this date, the document will be
• reconfirmed,
• withdrawn, or
• revised.
NOTE The attention of National Committees is drawn to the fact that equipment manufacturers and testing
organizations may need a transitional period following publication of a new, amended or revised IEC publication in
which to make products in accordance with the new requirements and to equip themselves for conducting new or
revised tests.
It is the recommendation of the committee that the content of this publication be adopted for implementation nationally
not earlier than 36 months from the date of publication.

8.14.1.101 Safety instructions for combined mitre and bench saws
a) Combined mitre and bench saws are intended to cut wood or wood-like products, they
cannot be used with abrasive cut-off wheels for cutting ferrous material such as bars,
rods, studs, etc. Abrasive dust causes moving parts such as the lower guard to jam. Sparks
from abrasive cutting will burn the lower guard, the kerf insert and other plastic parts.
b) Keep guards in place. Guards must be in working order and be properly mounted,
especially after a mode change. A guard that is loose, damaged, or is not functioning
correctly must be repaired or replaced.
c) Do not use the saw until the table is clear of all tools, wood scraps, etc., except for
the workpiece. Small debris or loose pieces of wood or other objects that contact the
revolving blade can be thrown with high speed.
d) Cut only one workpiece at a time. Stacked multiple workpieces cannot be adequately
clamped or braced and may bind on the blade or shift during cutting.
e) The cut-off piece must not be jammed or pressed by any means against the spinning
saw blade. If confined, for example using length stops, the cut-off piece could get wedged
against the blade and thrown violently.
f) Turn off the saw and disconnect the power cord when removing the table insert,
changing the saw blade or making adjustments to the riving knife, anti-kickback
device or saw blade guard, and when the machine is left unattended. Precautionary
measures will avoid accidents.
NOTE 101 If an anti-kickback device is not provided, the phrase "anti-kickback device" is omitted in item f)
above.
NOTE 102 At the manufacturer's discretion, it is possible to replace the term "anti-kickback device" by an
appropriate term such as "anti-kickback pawls" or "anti-kickback rollers" in item f) above.
g) Never leave the saw running unattended. Turn it off and do not leave the tool until it
comes to a complete stop. An unattended running saw is an uncontrolled hazard.
h) Mount or place the saw in a well-lit and level area where you can maintain good footing
and balance. It should be installed in an area with firm work surface that provides
enough room to easily handle the size of your workpiece. Cramped, dark areas, and
uneven slippery floors invite accidents. A level and firm work surface reduces the risk of the
saw becoming unstable.
i) Frequently clean and remove sawdust from under the saw table and/or the dust
collection device. Accumulated sawdust is combustible and may self-ignite.
j) The saw must be secured. A saw that is not properly secured may move or tip over.
k) Always use saw blades with correct size and shape (diamond versus round) of arbour
holes. Saw blades that do not match the mounting hardware of the saw will run off-centre,
causing loss of control.
l) Never use damaged or incorrect saw blade mounting means such as flanges, saw
blade washers, bolts or nuts. These mounting means were specially designed for your
saw, for safe operation and optimum performance.
m) Never stand on the saw, do not use it as a stepping stool. Serious injury could occur if
the tool is tipped or if the cutting tool is accidentally contacted.
n) Make sure that the saw blade is installed to rotate in the proper direction. Do not use
grinding wheels, wire brushes, or abrasive wheels on a saw. Improper saw blade
installation or use of accessories not recommended may cause serious injury.
o) Keep saw blades clean, sharp, and with sufficient set. Never use warped saw blades
or saw blades with cracked or broken teeth. Sharp and properly set saw blades minimize
binding, stalling and kickback.
8.14.1.102 Safety instructions for mitre saw mode
a) Use clamps to support the workpiece whenever possible. If supporting the workpiece
by hand, you must always keep your hand at least 100 mm from either side of the saw
blade. Do not use this saw to cut pieces that are too small to be securely clamped or
held by hand. If your hand is placed too close to the saw blade, there is an increased risk
of injury from blade contact.
b) The workpiece must be stationary and clamped or held against both the fence and the
table. Do not feed the workpiece into the blade or cut "freehand" in any way.
Unrestrained or moving workpieces could be thrown at high speeds, causing injury.
c) Push the saw through the workpiece. Do not pull the saw through the workpiece. To
make a cut, raise the saw head and pull it out over the workpiece without cutting, start
the motor, press the saw head down and push the saw through the workpiece. Cutting
on the pull stroke is likely to cause the saw blade to climb on top of the workpiece and
violently throw the blade assembly towards the operator.
d) Never cross your hand over the intended line of cutting either in front of or behind
the saw blade. Supporting the workpiece "cross handed", which means holding the
workpiece to the right of the saw blade with your left hand or vice versa, is very dangerous.
e) Do not reach behind the fence with either hand closer than 100 mm from either side
of the saw blade, to remove wood scraps, or for any other reason while the blade is
spinning. The proximity of the spinning saw blade to your hand may not be obvious and
you may be seriously injured.
– 16 – IEC 62841-3-11:2024 © IEC 2024
f) Inspect your workpiece before cutting. If the workpiece is bowed or warped, clamp it
with the outside bowed face toward the fence. Always make certain that there is no
gap between the workpiece, fence and table along the line of the cut. Bent or warped
workpieces can twist or shift and may cause binding on the spinning saw blade while cutting.
There should be no nails or foreign objects in the workpiece.
g) Plan your work. Every time you change the bevel or mitre angle setting, make sure
the adjustable fence is set correctly to support the workpiece and will not interfere
with the blade or the guarding system. Without turning the tool "ON" and with no
workpiece on the table, move the saw blade through a complete simulated cut to assure
there will be no interference or danger of cutting the fence.
NOTE 101 The phrase "bevel or" does not apply for saws without bevel adjustment in item g) above.
h) Provide adequate support such as table extensions, saw horses, etc. for a workpiece
that is wider or longer than the table top. Workpieces longer or wider than the table top
can tip if not securely supported. If the cut-off piece or workpiece tips, it can lift the lower
guard or be thrown by the spinning blade.
i) Do not use another person as a substitute for a table extension or as additional
support. Unstable support for the workpiece can cause the blade to bind or the workpiece
to shift during the cutting operation, pulling you and the helper into the spinning blade.
j) Always use a clamp or a fixture designed to properly support round material such as
rods or tubing. Rods have a tendency to roll while being cut, causing the blade to "bite"
and pull the work with your hand into the blade.
k) Let the blade reach full speed before contacting the workpiece. This will reduce the risk
of the workpiece being thrown.
l) If the workpiece or blade becomes jammed, turn the saw off. Wait for all moving parts
to stop and disconnect the plug from the power source and/or remove the battery
pack. Then work to free the jammed material. Continued sawing with a jammed workpiece
could cause loss of control or damage to the saw.
m) After finishing the cut, release the switch, hold the saw head down and wait for the
blade to stop before removing the cut-off piece. Reaching with your hand near the
coasting blade is dangerous.
n) Hold the handle firmly when making an incomplete cut or when releasing the switch
before the saw head is completely in the down position. The braking action of the saw
may cause the saw head to be suddenly pulled downward, causing a risk of injury.
NOTE 102 The warning in item n) above applies only for saws with a brake system.
8.14.1.103 Safety instructions for bench saw mode
1) Guarding related warnings
a) Always use saw blade guard, riving knife and anti-kickback device for every
through–cutting operation. For through-cutting operations where the saw blade cuts
completely through the thickness of the workpiece, the guar
