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 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 60745-2-5 has been prepared by IEC technical committee 116:
Safety of hand-held motor-operated electric tools.
This fifth edition cancels and replaces the fourth edition published in 2006, of which it
constitutes a technical revision.
Main changes include: in Clause 17, Endurance: introduction of endurance tests in practical
use for the guards of all types of saws; in Clause 19, Mechanical hazards: clarifications and
editorial improvement in respect to the guarding; and in Annex M, Safety of working stands for
operation with hand-held motor-operated electric tools: editorial improvements.

8.12.1.101.1 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 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 the power tool by insulated gripping surfaces only, 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
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.
8.12.1.101.2 Further safety instructions for all saws
Kickback causes and related warnings
– 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.
60745-2-5 © IEC:2010 – 9 –
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 sawing into existing walls or other blind areas. The
protruding blade may cut objects that can cause kickback.
8.12.1.101.3 Safety instructions for saws shown in Figures 101, 102 and 103
Lower guard function
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
Guard function
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 so that the blade is 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 base 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
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. Riving knife must be
replaced after plunge cutting. 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 riving knife is bent. Even a light interference can slow the
closing rate of a guard.
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;
– information about the allowed range of saw blade body thickness and the tooth set
of the blade.
103) Instructions to use only blade diameter(s) in accordance with the markings.
8.12.2 b) Addition:
101) Instructions for the blade changing procedure.
102) Instruction how to check the function of all blade guard operations.
103) 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.
104) Instruction on the correct use of the dust collection system.

8.12.2 c) Addition:
101) Instructions how to properly clean the tool and guarding system.
