Electric motor-operated hand-held tools, transportable tools and lawn and garden machinery - Safety - Part 2-5: Particular requirements for hand-held circular saws

IEC 62841-2-5:2014 applies to hand-held circular saws. This standard does not apply to saws designed for use with abrasive wheels. Saws designed for use with abrasive wheels as cut-off machines are covered by IEC 62841-2-22. The rated voltage is not more than 250 V for single-phase a.c. or d.c. tools, and 480 V for three-phase a.c. tools. The rated input is not more than 3 700 W. The limits for the applicability of this standard for battery tools is given in Annex K. This standard deals with the hazards presented by tools which are encountered by all persons in the normal use and reasonably foreseeable misuse of the tools. Hand-held electric tools, which can be mounted on a support or working stand for use as fixed tools without any alteration of the tool itself, are within the scope of this standard and such combination of a hand-held tool and a support is considered to be a transportable tool and thus covered by the relevant Part 3. 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. Key words: Saw, Circular, Cutting,
This publication is to be read in conjunction with IEC 62841-1:2014.

L'IEC 62841-2-5:2014 s'applique aux scies circulaires portatives. La présente norme ne s'applique pas aux scies destinées à être utilisées avec des roues abrasives. Les scies destinées à être utilisées avec des roues abrasives comme des machines de coupe sont traitées dans l'IEC 62841-2-22. The rated voltage is not more than 250 V for single-phase a.c. or d.c. tools, and 480 V for three-phase a.c. tools. The rated input is not more than 3 700 W. The limits for the applicability of this standard for battery tools is given in Annex K. This standard deals with the hazards presented by tools which are encountered by all persons in the normal use and reasonably foreseeable misuse of the tools. Les outils électroportatifs, qui peuvent être montés sur un support de travail pour être utilisés comme outils installés à poste fixe sans aucune modification de l'outil lui-même, sont compris dans le domaine d'application de la présente Norme et la combinaison d'un outil portatif et d'un support est considérée comme un outil portable, donc couvert par la Partie 3 applicable. L'attention des Comités Nationaux est attirée sur le fait que les fabricants d'appareils et les organismes d'essai peuvent avoir besoin d'une période transitoire après la publication d'une nouvelle publication IEC, ou d'une publication amendée ou révisée, pour fabriquer des produits conformes aux nouvelles exigences et pour adapter leurs équipements aux nouveaux essais ou aux essais révisés. Le comité recommande que le contenu de cette publication soit entériné au niveau national au plus tôt 12 mois et au plus tard 36 mois après la date de publication.

Overview - IEC 62841-2-5:2014 (Part 2‑5)

IEC 62841-2-5:2014 specifies safety requirements for electric motor‑operated hand‑held circular saws (hereafter “saws”). It is a particular part of the IEC 62841 series and is to be read in conjunction with IEC 62841-1:2014. The standard addresses hazards encountered in normal use and reasonably foreseeable misuse of hand‑held circular saws and transportable combinations (hand‑held saws mounted on supports). It excludes saws designed for abrasive wheels (these are covered by IEC 62841-2-22).

Scope limits include:

• Rated voltage not more than 250 V for single‑phase a.c. or d.c., and 480 V for three‑phase a.c.
• Rated input not more than 3 700 W
• Battery tool applicability and limits given in Annex K

The committee recommends a transitional adoption period (not earlier than 36 months from publication) to allow manufacturers and test labs to implement new requirements.

Key topics and technical requirements

This Part 2‑5 supplements IEC 62841-1 with circular saw‑specific provisions. Key topics include:

• Guarding system requirements (upper guard, lower guard, base plate, riving knife) and performance tests
• Kickback hazards - definitions and protective measures (mechanical design and guards)
• Mechanical hazards - blade exposure, cutting edge zone, plunge‑type saw considerations
• Starting, input and current, heating, overload and endurance tests to ensure safe operation under normal and abnormal conditions
• Protection against access to live parts and insulation/earthing provisions
• Noise and vibration measurement (Annex I) and battery tool requirements (Annex K)
• Specific annexes: riving knife (Annex AA), lower guard for saws without riving knife (Annex BB)
• Marking and instructions, test conditions, mechanical strength and construction requirements

Figures and dimensional requirements (e.g., base plate geometry, guard clearances, blade exposure angles) are provided to standardize safety margins and testing.

Applications - who uses this standard

IEC 62841-2-5 is essential for:

• Circular saw manufacturers (design, verification, technical files)
• Test laboratories and certification bodies performing safety and conformity testing
• Regulatory authorities and procurement teams specifying safe tools for workplaces
• R&D and safety engineers designing cutting tools and guarding systems
• Compliance professionals preparing user manuals, markings and safety instructions

Applying this standard helps reduce cutting‑related incidents (kickback, blade contact), ensures product conformity, and supports market access in regions adopting IEC/EN requirements.

Part 2-5: Particular requirements for hand-held circular 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.
This consolidated version of the official IEC Standard and its amendment has been
prepared for user convenience.
IEC 62841-2-5 edition 1.1 contains the first edition (2014-06) [documents 116/166/FDIS
and 116/180/RVD] and its amendment 1 (2025-02) [documents 116/860/FDIS and
116/878/RVD].

8.14.1.101 Additional safety instructions for circular saws
8.14.101.1 General
The additional safety instructions as specified in 8.14.1.101.2 to 8.14.1.101.6 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 Power Tool Safety
Warnings".
All notes are not to be printed; they are information for the designer of the manual.
8.14.1.101.2 Safety instructions for all saws
Cutting procedures
a) DANGER: 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 a maximum blade diameter of 140 mm or smaller, the words "Keep your
second hand on auxiliary handle, or motor housing" do not apply.
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 the workpiece in your hands or across your leg while cutting. Secure the
workpiece to a stable platform. It is important to support the work properly to minimise
body exposure, blade binding, or loss of control.
e) Hold the 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 could give the
operator an electric shock.
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 off-centre,
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.
8.14.1.101.3 Further safety instructions for all saws
Kickback causes and related warnings
– kickback is a sudden reaction to a pinched, jammed 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 jammed tightly by the kerf closing down, the blade stalls and
the motor reaction drives the unit rapidly back toward the operator;
– 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

REDLINE VERSION – 10 – IEC 62841-2-5:2014+AMD1:2025 CSV
© IEC 2025
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 a maximum blade diameter of 140 mm or smaller, the words "with both hands"
do not apply.
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 so that the
saw teeth are not engaged into the material. If a saw blade binds, 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 the cut. If blade adjustment shifts while cutting, it may cause binding and
kickback.
g) Use extra caution when sawing into existing walls or other blind areas. The
protruding blade may cut objects that can cause kickback.
8.14.1.101.4 Safety instructions for saws with pendulum guard and saws with tow
guard as shown in Figures 101, 102 and 103
Lower guard function
a) Check the lower guard for proper closing before each use. Do not operate the saw if
the lower guard does not move freely and close instantly. Never clamp or tie the
lower guard into the open position. If the saw is accidentally dropped, the 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 for "retracting handle" is possible.
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) The lower guard may be retracted manually only for special cuts such as "plunge
cuts" and "compound cuts". Raise the lower guard by the retracting handle and as
soon as the blade enters the material, the lower guard must be released. For all other
sawing, the lower guard should operate automatically.
NOTE Alternate wording for "retracting handle" is possible.
d) Always observe that the lower guard is covering the blade before placing the 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.
8.14.1.101.5 Safety instructions for plunge type saws shown in Figure 104
Guard function
a) Check the guard for proper closing before each use. Do not operate the saw if the
guard does not move freely and enclose the blade instantly. Never clamp or tie the
guard so that the blade is exposed. If the saw is accidentally dropped, the guard may
be bent. Check to make sure that the guard moves freely and does not touch the blade or
any other part, in all angles and depths of cut.

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. The guard may
operate sluggishly due to damaged parts, gummy deposits, or a build-up of debris.
c) Assure that the base plate of the saw will not shift while performing a “plunge cut”.
Blade shifting sideways will cause binding and likely kick back.
d) Always observe that the guard is covering the blade before placing the 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 the
switch is released.
8.14.1.101.6 Additional safety instructions for all saws with riving knife
Riving knife function
a) Use the appropriate saw blade for the riving knife. For the riving knife to function, the
body of the blade must be thinner than the riving knife and the cutting width of the blade
must be wider than the thickness of the riving knife.
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. The riving knife must be
replaced after plunge cutting. The riving knife causes interference during plunge cutting
and can create kickback.
NOTE This warning is not applicable for plunge type saws with a spring loaded riving knife.
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 the riving knife is bent. Even a light interference can slow the
closing rate of a guard.
8.14.2 a) Addition:
101) Instruction not to use any abrasive wheels;
102) For saws with riving knife the instruction shall include the following:
– instruction 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;
– information about the allowed range of saw blade body thickness and the tooth set
of the blade;
103) Instruction to use only blade diameter(s) in accordance with the markings;
104) Instruction to identify the correct saw blade to be used for the material to be cut;
105) Instruction to use only saw blades that are marked with a speed equal or higher than
the speed marked on the tool.
NOTE In Europe (EN 62841-2-5), the following additional requirement applies:
Instruction to use only saw blades recommended by the manufacturer, which conform to EN 847-1, if intended for
wood and analogous materials.
8.14.2 b) Addition:
101) Information regarding the maximum depth of cut;
102) Instruction for the blade changing procedure;
103) Instruction how to check the function of all blade guard operations;
104) Information regarding what materials can be cut. Instructions to avoid overheating the
blade tips and, if cutting plastics is permitted, to avoid melting the plastic;
105) Instructions on the correct use of the dust collection system;

retracted from the fully closed position to the maximum open working position and then
released. This sequence is repeated at a rate not less than 10 cycles per minute.
The sample used for this test may be positioned in a manner other than horizontal provided
that it can be shown that the alternate position is equal or more severe.
After completion of cycling test as specified above, the saw shall then comply with the tests of
17.101.2 and 17.101.3.
17.101.2 The test and measurement is carried out at maximum depth of cut and 0° bevel
angle. The saw is held or secured with the base plate in a horizontal position, the upper
guard being at the top.
Without any restoration or cleaning, the lower guard as shown in Figures 101, 102 and 103,
or the guarding system as shown in Figure 104, is retracted fully and then allowed to close.
The closing time from the fully open position to the fully closed position shall not exceed
0,3 s.
17.101.3 The following tests and measurements are carried out at maximum depth of cut,
at 0° bevel angle and in the following positions:
a) The saw is held with the base plate in the horizontal position, with the upper guard being
at the top.
b) The saw is then held with the base plate in the vertical position, with the front of the saw
pointing upwards.
For saws using a lower guard as shown in Figures 101 and 102, the lower guard is retracted
fully and then allowed to close. Without any alteration, the final position of the lower guard in
both cases shall be in contact with the lower guard stopper and shall not change as a result
of moving the base plate to a minimum depth-of-cut setting and the guarding shall comply
with the requirements of 19.102.3.
For saws using a lower guard as shown in Figure 103 or a guarding system as shown in
Figure 104, the lower guard or the guarding system is fully retracted, released and then
shall lock in the blade covering position.
17.102 Guarding System-Resistance
17.102.1 The guarding system shall be resistant against environmental and foreseeable
dust accumulation.
Compliance is checked by the tests of 17.102.2 and 17.102.3, as applicable.
During the tests, ventilation in the test area is permitted providing that air flow does not
influence the distribution of dust within the tool.
17.102.2 For a saw intended to cut wood based materials in accordance with 8.14.2 b) 104),
a new saw sample is subjected to 1 000 cuts through each of the materials and in the order as
specified below:
a) crosscutting soft wood;
b) crosscutting plywood with a minimum of 5 layers;
c) cutting standard medium density fibreboard (MDF) having a density between 650 kg/m³
and 850 kg/m .
REDLINE VERSION – 14 – IEC 62841-2-5:2014+AMD1:2025 CSV
© IEC 2025
The materials are stored indoors for 72 h prior to sawing. The thickness and length of each
material to be cut may vary in size, provided the thickness of the material is minimum 10 mm
and the cross sectional area of each cut is at least 30 mm times D.
Each cut is made with the saw set to 0° bevel angle and maximum depth of cut. The cutting
is conducted with a carbide-tipped general purpose combination blade. An external dust
extraction system attached to the saw shall not be used. A non-detachable dust collection
system shall be maintained per 8.14.2 b) 105).
NOTE Use of personal protective equipment will help to protect the operator during these tests.
During each cut, the lower guard or the guarding system shall cycle from the fully closed
position to the maximum open working position for each cutting cycle, without manual
assistance. Moreover, for plunge type saws with a spring loaded riving knife, the riving
knife shall cycle from its fully extended to the fully retracted position.
If the lower guard, guarding system or the riving knife fails to return to its normal position
at any time during the test, this is considered a failure.
After completion of all cuts as specified above, the saw is conditioned for 24 h in air at a
relative humidity of (93 ± 3) %. The temperature of the air is maintained within 2 K of any
convenient value between 20 °C and 30 °C.
The saw shall then comply with the tests of 17.101.2 and 17.101.3.
17.102.3 For a saw intended to cut materials such as plastic, ferrous metal or masonry in
accordance with 8.14.2 b) 104), a new saw sample for each specified material is subjected to
the tests as specified below.
− Plastics: 1 000 cuts through PVC. The thickness and length of the material may vary in
size, provided the cross sectional area of each cut is at least 0,012 D .
NOTE 1 The above formula simulates the cross sectional area of typical PVC pipes of a diameter approximately
equal to 2/3 of the maximum depth of cut of the saw. Sawing of such pipes is the predominant application for
plastic.
− Ferrous metals: 200 cuts through soft steel. The thickness and length of the material may
1,46 2
vary in size, provided the cross sectional area of each cut is at least 0,13 D in mm ,
where D is measured in mm.
NOTE 2 The above formula simulates the cross sectional area of typical metal pipes of a diameter approximately
equal to 1/2 of the maximum depth of cut of the saw. Sawing of such pipes is the predominant application for
metal.
− Masonry: 500 cuts through masonry fibreboard (fibre cement board). The thickness and
length of the fibreboard may vary in size, provided the thickness of the material is
minimum 10 mm and the cross sectional area of each cut is at least 30 mm times D.
Each cut is made with the saw set to 0° bevel angle. The depth of cut, the saw blade and the
rate of sawing shall be as specified for the respective material. An external dust extraction
system attached to the saw shall not be used. A non-detachable dust collection system shall
be maintained per 8.14.2 b) 105).

Part 2-5: Particular requirements for hand-held circular 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.
International Standard IEC 62841-2-5 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:
FDIS Report on voting
116/166/FDIS 116/180/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 first edition of IEC 62841-1 (2014).
This Part 2-5 supplements or modifies the corresponding clauses in IEC 62841-1, so as to
convert it into the IEC Standard: Particular requirements for hand-held circular saws.
Where a particular subclause of Part 1 is not mentioned in this Part 2-5, that subclause
applies as far as reasonable. Where this standard states “addition”, “modification” or
“replacement”, the relevant text in Part 1 is to be adapted accordingly.
The following print types are used:
– requirements: in roman type;
– test specifications: in italic type;
– notes: in small roman type.
The terms defined in Clause 3 are printed in bold typeface.
Subclauses, notes and figures which are additional to those in Part 1 are numbered starting
from 101.
A list of all parts of the IEC 62841 series, 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.
The committee has decided that the contents of this publication will remain unchanged until
the stability date indicated on the IEC web site under "http://webstore.iec.ch" in the data
related to the specific publication. At this date, the publication will be
• reconfirmed,
• withdrawn,
• replaced by a revised edition, or
• amended.
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 Additional safety instructions for circular saws
8.14.101.1 General
The additional safety instructions as specified in 8.14.1.101.2 to 8.14.1.101.6 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 Power Tool Safety
Warnings".
All notes are not to be printed; they are information for the designer of the manual.
8.14.1.101.2 Safety instructions for all saws
Cutting procedures
DANGER: Keep hands away from cutting area and the blade. Keep your second
a)
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 a maximum blade diameter of 140 mm or smaller, the words "Keep your
second hand on auxiliary handle, or motor housing" do not apply.
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 the workpiece in your hands or across your leg while cutting. Secure the
workpiece to a stable platform. It is important to support the work properly to minimise
body exposure, blade binding, or loss of control.
e) Hold the 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 could give the
operator an electric shock.
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 off-centre,
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.
8.14.1.101.3 Further safety instructions for all saws
Kickback causes and related warnings
– kickback is a sudden reaction to a pinched, jammed 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 jammed tightly by the kerf closing down, the blade stalls and
the motor reaction drives the unit rapidly back toward the operator;
– 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 a maximum blade diameter of 140 mm or smaller, the words "with both hands"
do not apply.
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 so that the
saw teeth are not engaged into the material. If a saw blade binds, 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 the cut. If blade adjustment shifts while cutting, it may cause binding and
kickback.
g) Use extra caution when sawing into existing walls or other blind areas. The
protruding blade may cut objects that can cause kickback.

8.14.1.101.4 Safety instructions for saws with pendulum guard and saws with tow
guard as shown in Figures 101, 102 and 103
Lower guard function
a) Check the lower guard for proper closing before each use. Do not operate the saw if
the lower guard does not move freely and close instantly. Never clamp or tie the
lower guard into the open position. If the saw is accidentally dropped, the 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 for "retracting handle" is possible.
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) The lower guard may be retracted manually only for special cuts such as "plunge
cuts" and "compound cuts". Raise the lower guard by the retracting handle and as
soon as the blade enters the material, the lower guard must be released. For all other
sawing, the lower guard should operate automatically.
NOTE Alternate wording for "retracting handle" is possible.
d) Always observe that the lower guard is covering the blade before placing the 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.
8.14.1.101.5 Safety instructions for plunge type saws shown in Figure 104
Guard function
a) Check the guard for proper closing before each use. Do not operate the saw if the
guard does not move freely and enclose the blade instantly. Never clamp or tie the
guard so that the blade is exposed. If the saw is accidentally dropped, the guard may
be bent. Check to make sure that the guard moves freely and does not touch the blade or
any other part, in all angles and depths of cut.
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. The guard may
operate sluggishly due to damaged parts, gummy deposits, or a build-up of debris.
c) Assure that the base plate of the saw will not shift while performing a “plunge cut”.
Blade shifting sideways will cause binding and likely kick back.
d) Always observe that the guard is covering the blade before placing the 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 the
switch is released.
8.14.1.101.6 Additional safety instructions for all saws with riving knife
Riving knife function
a) Use the appropriate saw blade for the riving knife. For the riving knife to function, the
body of the blade must be thinner than the riving knife and the cutting width of the blade
must be wider than the thickness of the riving knife.
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. The riving knife must be
replaced after plunge cutting. The riving knife causes interference during plunge cutting
and can create kickback.
NOTE This warning is not applicable for plunge type saws with a spring loaded riving knife.

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 the riving knife is bent. Even a light interference can slow the
closing rate of a guard.
8.14.2 a) Addition:
101) Instruction not to use any abrasive wheels;
102) For saws with riving knife the instruction shall include the following:
– instruction 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;
– information about the allowed range of saw blade body thickness and the tooth set
of the blade;
103) Instruction to use only blade diameter(s) in accordance with the markings;
104) Instruction to identify the correct saw blade to be used for the material to be cut;
105) Instruction to use only saw blades that are marked with a speed equal or higher than
the speed marked on the tool.
NOTE In Europe (EN 62841-2-5), the following additional requirement applies:
Instruction to use only saw blades recommended by the manufacturer, which conform to EN 847-1, if intended for
wood and analogous materials.
8.14.2 b) Addition:
101) Information regarding the maximum depth of cut;
102) Instruction for the blade changing procedure;
103) Instruction how to check the function of all blade guard operations;
104) Information regarding what materials can be cut. Instructions to avoid overheating the
blade tips and, if cutting plastics is permitted, to avoid melting the plastic;
105) Instructions on the correct use of the dust collection system;
106) Instruction to wear a dust mask.
8.14.2 c) Addition:
101) Instruction how to properly clean the tool and guarding system.

This clause of Part 1 is applicable, except as follows:
17.101 Guarding system – Longevity
17.101.1 To provide sufficient endurance for extended use, the guarding system shall have
a longevity of 50 000 operating cycles.
Compliance is checked by a new saw sample completing the following test.
The saw is to be set for 0° bevel angle with the base plate in horizontal position and the
blade removed. The lower guard, or the guarding system as shown in Figure 104, is
retracted from the fully closed position to the maximum open working position and then
released. This sequence is repeated at a rate not less than 10 cycles per minute.
The sample used for this test may be positioned in a manner other than horizontal provided
that it can be shown that the alternate position is equal or more severe.
After completion of cycling test as specified above, the saw shall then comply with the tests of
17.101.2 and 17.101.3.
17.101.2 The test and measurement is carried out at maximum depth of cut and 0° bevel
angle. The saw is held or secured with the base plate in a horizontal position, the upper
guard being at the top.
Without any restoration or cleaning, the lower guard as shown in Figures 101, 102 and 103,
or the guarding system as shown in Figure 104, is retracted fully and then allowed to close.
The closing time from the fully open position to the fully closed position shall not exceed
0,3 s.
17.101.3 The following tests and measurements are carried out at maximum depth of cut,
at 0° bevel angle and in the following positions:
a) The saw is held with the base plate in the horizontal position, with the upper guard being
at the top.
b) The saw is then held with the base plate in the vertical position, with the front of the saw
pointing upwards.
For saws using a lower guard as shown in Figures 101 and 102, the lower guard is retracted
fully and then allowed to close. Without any alteration, the final position of the lower guard in
both cases shall be in contact with the lower guard stopper and shall not change as a result
of moving the base plate to a minimum depth-of-cut setting and the guarding shall comply
with the requirements of 19.102.3.
For saws using a lower guard as shown in Figure 103 or a guarding system as shown in
Figure 104, the lower guard or the guarding system is fully retracted, released and then
shall lock in the blade covering position.
17.102 Guarding System-Resistance
17.102.1 The guarding system shall be resistant against environmental and foreseeable
dust accumulation.
Compliance is checked by the tests of 17.102.2 and 17.102.3, as applicable.
During the tests, ventilation in the test area is permitted providing that air flow does not
influence the distribution of dust within the tool.
17.102.2 For a saw intended to cut wood based materials in accordance with 8.14.2 b) 104),
a new saw sample is subjected to 1 000 cuts through each of the materials and in the order as
specified below:
a) crosscutting soft wood;
b) crosscutting plywood with a minimum of 5 layers;
c) cutting standard medium density fibreboard (MDF) having a density between 650 kg/m³
and 850 kg/m .
The materials are stored indoors for 72 h prior to sawing. The thickness and length of each
material to be cut may vary in size, provided the thickness of the material is minimum 10 mm
and the cross sectional area of each cut is at least 30 mm times D.
Each cut is made with the saw set to 0° bevel angle and maximum depth of cut. The cutting
is conducted with a carbide-tipped general purpose combination blade. An external dust
extraction system attached to the saw shall not be used. A non-detachable dust collection
system shall be maintained per 8.14.2 b) 105).
NOTE Use of personal protective equipment will help to protect the operator during these tests.
During each cut, the lower guard or the guarding system shall cycle from the fully closed
position to the maximum open working position for each cutting cycle, without manual
assistance. Moreover, for plunge type saws with a spring loaded riving knife, the riving
knife shall cycle from its fully extended to the fully retracted position.
If the lower guard, guarding system or the riving knife fails to return to its normal position
at any time during the test, this is considered a failure.
After completion of all cuts as specified above, the saw is conditioned for 24 h in air at a
relative humidity of (93 ± 3) %. The temperature of the air is maintained within 2 K of any
convenient value between 20 °C and 30 °C.
The saw shall then comply with the tests of 17.101.2 and 17.101.3.
17.102.3 For a saw intended to cut materials such as plastic, ferrous metal or masonry in
accordance with 8.14.2 b) 104), a new saw sample for each specified material is subjected to
the tests as specified below.
– 14 – IEC 62841-2-5:2014 © IEC 2014
− Plastics: 1 000 cuts through PVC. The thickness and length of the material may vary in
size, provided the cross sectional area of each cut is at least 0,012 D .
NOTE 1 The above formula simulates the cross sectional area of typical PVC pipes of a diameter approximately
equal to 2/3 of the maximum depth of cut of the saw. Sawing of such pipes is the predominant application for
plastic.
− Ferrous metals: 200 cuts through soft steel. The thickness and length of the material may
1,46 2
vary in size, provided the cross sectional area of each cut is at least 0,13 D in mm ,
where D is measured in mm.
NOTE 2 The above formula simulates the cross sectional area of typical metal pipes of a diameter approximately
equal to 1/2 of the maximum depth of cut of the saw. Sawing of such pipes is the predominant application for
metal.
− Masonry: 500 cuts through masonry fibreboard (fibre cement board). The thickness and
length of the fibreboard may vary in size, provided the thickness of the material is
minimum 10 mm and the cross sectional area of each cut is at least 30 mm times D.
Each cut is made with the saw set to 0° bevel angle. The depth of cut, the saw blade and the
rate of sawing shall be as specified for the respective material. An external dust extraction
system attached to the saw shall not be used. A non-detachable dust collection system shall
be maintained per 8.14.2 b) 105).
NOTE 3 Use of personal protective equipment will help to protect the operator during these tests.
During each cut, the lower guard or the guarding system shall cycle from the fully closed
position to the maximum open working position for each cutting cycle, without manual
assistance. Moreover, for plunge type saws with a spring loaded riving knife, the riving
knife shall cycle from its fully extended to the fully retracted position.
If the lower guard, guarding system or the riving knife fails to return to its normal position
at any time during the test, this is considered a failure.
After completion of all cuts as specified above, the saw is conditioned for 24 h in air at a
± 3) %. The temperature of the air is maintained within 2 K of any
relative humidity of (93
convenient value between 20 °C and 30 °C.
