Part 2-5: Particular requirements for circular saws
FOREWORD
1) The IEC (International Electrotechnical Commission) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of the 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, the IEC publishes International Standards. 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. The 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 the 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 National Committees.
3) The documents produced have the form of recommendations for international use and are published in the form
of standards, technical specifications, technical reports or guides and they are accepted by the National
Committees in that sense.
4) In order to promote international unification, IEC National Committees undertake to apply IEC International
Standards transparently to the maximum extent possible in their national and regional standards. Any
divergence between the IEC Standard and the corresponding national or regional standard shall be clearly
indicated in the latter.
5) The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with one of its standards.
6) Attention is drawn to the possibility that some of the elements of this International Standard may be the subject
of patent rights. The IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 60745-2-5 has been prepared by subcommittee 61F: Safety of
hand-held motor-operated electric tools, of IEC technical committee 61: Safety of household
and similar electrical appliances.
This third edition cancels and replaces the second edition published in 1993, of which it
constitutes a technical revision.
The text of this standard is based on the following documents:
FDIS Report on voting
61F/503/FDIS 61F/512/RVD
Full information on the voting for the approval of this standard can be found in the report on
voting indicated in the above table.
This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.
This part 2-5 is to be used in conjunction with the third edition of IEC 60745-1: Hand-held
motor-operated electric tools – Safety – Part 1: General Requirements. When this standard
states “addition”, “modification” or “replacement”, the relevant text in Part 1 is to be adapted
accordingly.
– 4 – 60745-2-5 IEC:2003(E)
NOTE in this standard, the following print types are used:
– requirements: in roman type;
– test specifications: in italic type;
– notes: in smaller roman type.
Subclauses, tables and figures which are additional to those in Part 1 are numbered starting from 101; additional
annexes are lettered AA, BB, etc.
The committee has decided that the contents of this publication will remain unchanged until
January 2007. At this date, the publication will be
• reconfirmed;
• withdrawn;
• replaced by a revised edition, or
• amended.
A bilingual version of this publication may be issued at a later date.

60745-2-5 IEC:2003(E) – 7 –
8.12.2 a) Addition:
101) Instructions not to use any abrasive wheels
102) For saws with riving knife the instruction shall include the following:
Instructions to ensure that the riving knife is adjusted so that the distance between the
riving knife and the rim of the blade is not more than 5 mm, and the rim of the blade
does not extend more than 5 mm beyond the lowest edge of the riving knife.
8.12.2 b) Addition
101) Instructions for the blade changing procedure
Additional subclause:
8.12.101 The following additional safety instructions shall be given. If in English they shall
be verbatim and in the following order as applicable and equivalent in any other language.
This part may be printed separately from the General Safety Instructions. All notes are not to
be printed, they are information for the designer of the manual.
8.12.101.1 Safety instructions for all saws
DANGER:
a) Keep hands away from cutting area and the blade. Keep your second hand on
auxiliary handle, or motor housing. If both hands are holding the saw, they cannot be
cut by the blade.
NOTE For circular saws with 140 mm or smaller diameter blades, the "Keep your second hand on auxiliary
handle, or motor housing" may be omitted.
b) Do not reach underneath the workpiece. The guard cannot protect you from the blade
below the workpiece.
c) Adjust the cutting depth to the thickness of the workpiece. Less than a full tooth of
the blade teeth should be visible below the workpiece.
d) Never hold piece being cut in your hands or across your leg. Secure the workpiece
to a stable platform. It is important to support the work properly to minimize body
exposure, blade binding, or loss of control.
e) Hold power tool by insulated gripping surfaces when performing an operation where
the cutting tool may contact hidden wiring or its own cord. Contact with a "live" wire
will also make exposed metal parts of the power tool "live" and shock the operator.
f) When ripping always use a rip fence or straight edge guide. This improves the
accuracy of cut and reduces the chance of blade binding.
g) Always use blades with correct size and shape (diamond versus round) of arbour
holes. Blades that do not match the mounting hardware of the saw will run eccentrically,
causing loss of control.
h) Never use damaged or incorrect blade washers or bolt. The blade washers and bolt
were specially designed for your saw, for optimum performance and safety of operation.
8.12.101.2 Further safety instructions for all saws
Causes and operator prevention of kickback:
− kickback is a sudden reaction to a pinched, bound or misaligned saw blade, causing an
uncontrolled saw to lift up and out of the workpiece toward the operator;
− when the blade is pinched or bound tightly by the kerf closing down, the blade stalls and
the motor reaction drives the unit rapidly back toward the operator;
– 8 – 60745-2-5 IEC:2003(E)
− if the blade becomes twisted or misaligned in the cut, the teeth at the back edge of the
blade can dig into the top surface of the wood causing the blade to climb out of the kerf
and jump back toward the operator.
Kickback is the result of saw misuse and/or incorrect operating procedures or conditions and
can be avoided by taking proper precautions as given below.
a) Maintain a firm grip with both hands on the saw and position your arms to resist
kickback forces. Position your body to either side of the blade, but not in line with
the blade. Kickback could cause the saw to jump backwards, but kickback forces can be
controlled by the operator, if proper precautions are taken.
NOTE For circular saws with 140 mm or smaller diameter blades, the words "with both hands" may be omitted.
b) When blade is binding, or when interrupting a cut for any reason, release the trigger
and hold the saw motionless in the material until the blade comes to a complete
stop. Never attempt to remove the saw from the work or pull the saw backward while
the blade is in motion or kickback may occur. Investigate and take corrective actions
to eliminate the cause of blade binding.
c) When restarting a saw in the workpiece, centre the saw blade in the kerf and check
that saw teeth are not engaged into the material. If saw blade is binding, it may walk
up or kickback from the workpiece as the saw is restarted.
d) Support large panels to minimise the risk of blade pinching and kickback. Large
panels tend to sag under their own weight. Supports must be placed under the panel on
both sides, near the line of cut and near the edge of the panel.
e) Do not use dull or damaged blades. Unsharpened or improperly set blades produce
narrow kerf causing excessive friction, blade binding and kickback.
f) Blade depth and bevel adjusting locking levers must be tight and secure before
making cut. If blade adjustment shifts while cutting, it may cause binding and kickback.
g) Use extra caution when making a "plunge cut" into existing walls or other blind
areas. The protruding blade may cut objects that can cause kickback.
8.12.101.3 Safety instructions for saws shown in Figures 101, 102 and 103
a) Check lower guard for proper closing before each use. Do not operate the saw if
lower guard does not move freely and close instantly. Never clamp or tie the lower
guard into the open position. If saw is accidentally dropped, lower guard may be bent.
Raise the lower guard with the retracting handle and make sure it moves freely and does
not touch the blade or any other part, in all angles and depths of cut.
NOTE Alternate wording may be substituted for "retracting handle."
b) Check the operation of the lower guard spring. If the guard and the spring are not
operating properly, they must be serviced before use. Lower guard may operate
sluggishly due to damaged parts, gummy deposits, or a build-up of debris.
c) Lower guard should be retracted manually only for special cuts such as "plunge
cuts" and "compound cuts." Raise lower guard by retracting handle and as soon as
blade enters the material, the lower guard must be released. For all other sawing, the
lower guard should operate automatically.
NOTE Alternate wording may be substituted for "retracting handle."
d) Always observe that the lower guard is covering the blade before placing saw down
on bench or floor. An unprotected, coasting blade will cause the saw to walk backwards,
cutting whatever is in its path. Be aware of the time it takes for the blade to stop after
switch is released.
8.12.101.4 Safety instructions for saws shown in Figure 104
a) Check guard for proper closing before each use. Do not operate the saw if guard
does not move freely and enclose the blade instantly. Never clamp or tie the guard
with the blade exposed. If saw is accidentally dropped, guard may be bent. Check to
make sure that guard moves freely and does not touch the blade or any other part, in all
angles and depths of cut.
60745-2-5 IEC:2003(E) – 9 –
b) Check the operation and condition of the guard return spring. If the guard and the
spring are not operating properly, they must be serviced before use. Guard may
operate sluggishly due to damaged parts, gummy deposits, or a build-up of debris.
c) Assure that the guide plate of the saw will not shift while performing the “plunge
cut” when the blade bevel setting is not at 90°. Blade shifting sideways will cause
binding and likely kick back.
d) Always observe that the guard is covering the blade before placing saw down on
bench or floor. An unprotected, coasting blade will cause the saw to walk backwards,
cutting whatever is in its path. Be aware of the time it takes for the blade to stop after
switch is released.
8.12.101.5 Additional safety instructions for all saws with riving knife
a) Use the appropriate riving knife for the blade being used. For the riving knife to work,
it must be thicker than the body of the blade but thinner than the tooth set of the blade.
b) Adjust the riving knife as described in this instruction manual. Incorrect spacing,
positioning and alignment can make the riving knife ineffective in preventing kickback.
c) Always use the riving knife except when plunge cutting. Riving knife must be
replaced after plunge cutting. Riving knife causes interference during plunge cutting and
can create kickback.
d) For the riving knife to work, it must be engaged in the workpiece. The riving knife is
ineffective in preventing kickback during short cuts.
e) Do not operate the saw if riving knife is bent. Even a light interference can slow the
closing rate of a guard.

19 Mechanical hazards
This clause of Part 1 is applicable, except as follows:
19.1 Replacement:
Saws shall be so guarded as to minimise the risk of accidental access to the rotating blade as
far as conditions of use will permit. Guarding systems shall not be removable without the aid
of a tool.
There are four commonly used guarding systems for saws, as shown in Figures 101, 102, 103
and 104. Guarding systems can be designed with the blade on the right or on the left side of
the saw. These guarding systems shall comply with the requirements of 19.101 and 19.102.
Each one of these guarding system types can be designed with or without the riving knife
(item 6 in the figures).
− If a guarding system is designed with a riving knife, it shall meet the additional
requirements of Annex AA.
− If a guarding system is designed without a riving knife, it shall meet the additional
requirements of Annex BB.
Other means of achieving the necessary degree of mechanical safety are allowed, provided
that these are as equally effective and reliable as those specified.
Compliance is checked by inspection.
Additional subclauses:
19.101 Guarding above the guide plate
19.101.1 The blade above the guide plate shall be guarded by the upper guard.
19.101.2 Apertures in the guarding system above the guide plate, unless otherwise specified
below, shall be designed such that the test probe ‘a’ of Figure 105, when inserted at any
angle and to the depth allowed by its stop, shall not be able to contact the cutting edge zone
of any recommended blade.
60745-2-5 IEC:2003(E) – 11 –
19.101.2.1 On the motor side of the upper guard, adjacent to the cutting edge zone at the
front of the blade an aperture may be provided for viewing the line of the cut. This viewing
aperture shall either meet the requirements of 19.101.2, as illustrated in Figure 106, or it shall
be limited by proximity and height restrictions.
ƒ Proximity restriction
The straight line distance from a defined measuring point on the auxiliary handle surface to
the cutting edge zone of any recommended blade shall be a minimum of 120 mm as shown in
Figure 107. If there is no auxiliary handle provided, the distance shall be measured from the
motor casing.
Compliance is checked by the following measurements, which shall be conducted with the
guide plate set to maximum depth of cut and 90°.
To establish the measuring point on the auxiliary handle or the motor casing, follow the
procedure outlined below.
a) Establish the closest (A) and

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 provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with an IEC Publication.
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.

suivantes:
s’assurer que le couteau diviseur est réglé de façon que la distance entre le couteau
diviseur et le contour de la lame de scie ne soit pas supérieure à 5 mm, et que le
contour de la lame de scie ne s’étende pas à plus de 5 mm au-delà du bord le plus
bas du couteau diviseur.
8.12.2 b) Addition
101) Instructions pour la procédure de changement de lame
Paragraphe complémentaire:
8.12.101 Les instructions de sécurité complémentaires suivantes doivent être données. Si
elles sont rédigées en anglais, elles doivent figurer textuellement et dans l’ordre suivant, si
applicables et équivalentes dans toute autre langue. La présente partie peut être imprimée
séparément des instructions générales de sécurité. Toutes les notes ne doivent pas être
imprimées, elles constituent des informations pour le concepteur du manuel.
8.12.101.1 Instructions de sécurité pour toutes les scies
DANGER:
a) N’approchez pas les mains de la zone de coupe et de la lame. Gardez la deuxième
main sur la poignée auxiliaire ou sur le boîtier du moteur. Si les deux mains tiennent
la scie, elles ne peuvent pas être coupées par la lame.
NOTE Pour les scies circulaires dont le diamètre des lames est inférieur ou égal à 140 mm, il est possible
que l’instruction « Gardez la deuxième main sur la poignée auxiliaire ou sur le boîtier du moteur » ne figure
pas.
b) N’exposez aucune partie de votre corps sous la pièce à travailler. Le protecteur ne
peut pas vous protéger de la lame sous la pièce à travailler.
c) Ajustez la profondeur de coupe à l’épaisseur de la pièce à travailler. Il convient que
moins de la totalité d’une dent parmi toutes les dents de la lame soit visible sous la pièce
à travailler.
d) Ne tenez jamais la pièce à débiter dans vos mains ou sur vos jambes. Assurez-vous
que la pièce à travailler se trouve sur une plate-forme stable. Il est important que la
pièce à travailler soit soutenue convenablement, afin de minimiser l’exposition du corps,
le grippage de la lame, ou la perte de contrôle.
e) Maintenez l’outil par les surfaces de prise isolantes, si l’outil coupant, en marche,
peut être en contact avec des conducteurs cachés ou avec son propre câble. Le
contact avec un fil « sous tension » mettra également « sous tension » les parties
métalliques exposées de l’outil et provoquera un choc électrique sur l’opérateur.
f) Lors d’une coupe, utilisez toujours un guide parallèle ou un guide à bords droits.
Cela améliore la précision de la coupe et réduit les risques de grippage de la lame.
g) Utilisez toujours des lames dont la taille et la forme (diamètre et rond) des alésages
centraux sont convenables. Les lames qui ne correspondent pas aux éléments de
montage de la scie ne fonctionneront pas bien, provoquant une perte de contrôle.
h) N’utilisez jamais de rondelles ou de boulons de lames endommagés ou inadaptés.
Les rondelles et les boulons de lames ont été spécialement conçus pour votre scie, afin
de garantir une performance optimale et une sécurité de fonctionnement.
60745-2-5 IEC:2006 – 15 –
8.12.2 a) Addition:
101) Instructions not to use any abrasive wheels
102) For saws with riving knife the instruction shall include the following:
Instructions to ensure that the riving knife is adjusted so that the distance between the
riving knife and the rim of the blade is not more than 5 mm, and the rim of the blade
does not extend more than 5 mm beyond the lowest edge of the riving knife.
8.12.2 b) Addition
101) Instructions for the blade changing procedure
Additional subclause:
8.12.101 The following additional safety instructions shall be given. If in English they shall
be verbatim and in the following order as applicable and equivalent in any other language.
This part may be printed separately from the General Safety Instructions. All notes are not to
be printed, they are information for the designer of the manual.
8.12.101.1 Safety instructions for all saws
DANGER:
a) Keep hands away from cutting area and the blade. Keep your second hand on
auxiliary handle, or motor housing. If both hands are holding the saw, they cannot be
cut by the blade.
NOTE For circular saws with 140 mm or smaller diameter blades, the "Keep your second hand on auxiliary
handle, or motor housing" may be omitted.
b) Do not reach underneath the workpiece. The guard cannot protect you from the blade
below the workpiece.
c) Adjust the cutting depth to the thickness of the workpiece. Less than a full tooth of
the blade teeth should be visible below the workpiece.
d) Never hold piece being cut in your hands or across your leg. Secure the workpiece
to a stable platform. It is important to support the work properly to minimize body
exposure, blade binding, or loss of control.
e) Hold power tool by insulated gripping surfaces when performing an operation where
the cutting tool may contact hidden wiring or its own cord. Contact with a "live" wire
will also make exposed metal parts of the power tool "live" and shock the operator.
f) When ripping always use a rip fence or straight edge guide. This improves the
accuracy of cut and reduces the chance of blade binding.
g) Always use blades with correct size and shape (diamond versus round) of arbour
holes. Blades that do not match the mounting hardware of the saw will run eccentrically,
causing loss of control.
h) Never use damaged or incorrect blade washers or bolt. The blade washers and bolt
were specially designed for your saw, for optimum performance and safety of operation.
