Part 2-5: Particular requirements for 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 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.
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 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 fourth edition cancels and replaces the third edition published in 2003, of which it
constitutes a technical revision. Main changes include: Clause 19: Mechanical hazards,
clarifications in respect to the guarding, editorial modifications in Annex AA, the addition of
Annex M: Safety of working stands for operation with hand-held motor-operated electric tools

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.
8.12.1.101.1 Safety instructions for all saws
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 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.

60745-2-5  IEC:2006 – 17 –
8.12.1.101.2 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;
− 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.

60745-2-5  IEC:2006 – 19 –
8.12.1.101.3 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 may 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.
8.12.1.101.4 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.
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.
8.12.1.101.5 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.

60745-2-5  IEC:2006 – 21 –
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.

18 Abnormal operation
This clause of Part 1 is applicable.
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.
19.3 This subclause is not applicable.
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.
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. If the motor casing is not suitable for grasping, the measurement is made from
the geometric centre of the switch trigger grasping surface with the switch in the off position.

60745-2-5  IEC:2006 – 25 –
Compliance is checked by the following measurements, which shall be conducted with the
guide plate set to any depth of cut and 90°.
To establish the measuring point on the auxiliary handle or the motor casing, follow the
procedure outlined below. The guide plate is set to maximum depth of cut and 90°.
a) Establish the closest (A) and the most distant (B) points on the auxiliary handle or motor
casing defined grasping surface from the blade. For the motor casing, the closest (A) point
to the blade is assumed to be in the plane of the main handle farthest from the blade.
Equidistant between points (A) and (B), but not more than 45 mm away from point (A),
draw the vertical intersecting line of the plane parallel with the blade and the surface of
the auxiliary handle or motor casing, as applicable.
b) Establish the closest (C) and the most distant (D) point from the plane of the guide plate
on the auxiliary handle or motor casing defined grasping surface. Equidistant between
points (C) and (D), draw the horizontal intersecting line of the plane parallel with the guide
plate and the surface of the auxiliary handle or motor casing, as applicable.
c) The intersection of the vertical and horizontal lines drawn on the applicable surface is the
defined measuring point.
ƒ Height restriction
The height of the viewing aperture (H) measured from the bottom plane of the guide plate, as
shown in Figure 108a, is limited to the point where the line of sight, from the ordinary
operator’s head position to the tip of the saw blade cutting the wood, is intersecting the outer
surface of the upper guard.
The maximum permissible height H, in millimetres, is given by the formula
848 U
H =
205 + S
where
U is the maximum distance, in millimetres, from the cutting edge zone to the outer surface of
the upper guard at the top end of the viewing aperture, measured perpendicularly to the
plane of the saw blade (see Figure 108b);
S is the distance, in millimetres, from the plane of the saw blade to a parallel centreplane of
the switch handle (see Figure 108c).
Compliance is checked by measurement, which shall be conducted with the guide plate set to
maximum depth of cut and 90°.
19.101.2.2 The upper guard on the side opposite the motor need not completely cover the
blade.
