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 62841-3-9 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:

5.101 Procedure to determine the horizontal cutting capacity
The mitre saw is fitted with a 2 mm thick steel disc of diameter D in place of the saw blade
and is set to 0° bevel angle. The saw unit is at its fully down position and, for a mitre saw
with a sliding function, the saw unit is at its maximum extended horizontal position from the
fence. The mitre saw is set for the mitre angle for which the horizontal cutting capacity
measurement is desired.
Horizontal cutting capacity:
The horizontal cutting capacity is the perpendicular distance measured in the plane of the
table top from the fence to the intersect point of the steel disc periphery in quadrant “C” with
the plane of the table top.
6 Radiation, toxicity and similar hazards
This clause of Part 1 is applicable.
7 Classification
This clause of Part 1 is applicable.
8 Marking and instructions
This clause of Part 1 is applicable, except as follows:
8.1 Addition:
Mitre saws shall be marked with:
– rated no-load speed of the output spindle.
8.3 Addition:
Mitre saws shall be marked with the saw blade diameter(s). The marked value(s) shall not be
larger than D and shall not be less than 0,975 D.
Mitre saws shall be marked with the direction of rotation of the spindle, indicated in a visible
location on the tool in the vicinity of the saw blade, such as on the saw blade guard, by an
arrow raised or recessed or by any other means no less visible and indelible.
The table top on each side of the saw blade shall be marked with a sign as follows:

– 10 – IEC 62841-3-9:2014 © IEC 2014

This symbol needs not be in accordance with the colour requirements of ISO 3864-2.
8.14.1 Addition:
The additional safety instructions as specified in 8.14.1.101 shall be given. This part may be
printed separately from the “General Power Tool Safety Warnings”.
8.14.1.101 Safety instructions for mitre saws
a) Mitre saws are intended to cut wood or wood-like products, they cannot be used
with abrasive cut-off wheels for cutting ferrous material such as bars, rods, studs,
etc. Abrasive dust causes moving parts such as the lower guard to jam. Sparks from
abrasive cutting will burn the lower guard, the kerf insert and other plastic parts.
b) Use clamps to support the workpiece whenever possible. If supporting the
workpiece by hand, you must always keep your hand at least 100 mm from either
side of the saw blade. Do not use this saw to cut pieces that are too small to be
securely clamped or held by hand. If your hand is placed too close to the saw blade,
there is an increased risk of injury from blade contact.
c) The workpiece must be stationary and clamped or held against both the fence and
the table. Do not feed the workpiece into the blade or cut “freehand” in any way.
Unrestrained or moving workpieces could be thrown at high speeds, causing injury.
d) Push the saw through the workpiece. Do not pull the saw through the workpiece. To
make a cut, raise the saw head and pull it out over the workpiece without cutting,
start the motor, press the saw head down and push the saw through the workpiece.
Cutting on the pull stroke is likely to cause the saw blade to climb on top of the workpiece
and violently throw the blade assembly towards the operator.
NOTE The above warning is omitted for a simple pivoting arm mitre saw.
e) Never cross your hand over the intended line of cutting either in front or behind the
saw blade. Supporting the workpiece “cross handed” i.e. holding the workpiece to the
right of the saw blade with your left hand or vice versa is very dangerous.
f) Do not reach behind the fence with either hand closer than 100 mm from either side
of the saw blade, to remove wood scraps, or for any other reason while the blade is
spinning. The proximity of the spinning saw blade to your hand may not be obvious and
you may be seriously injured.
g) Inspect your workpiece before cutting. If the workpiece is bowed or warped, clamp it
with the outside bowed face toward the fence. Always make certain that there is no
gap between the workpiece, fence and table along the line of the cut. Bent or warped
workpieces can twist or shift and may cause binding on the spinning saw blade while
cutting. There should be no nails or foreign objects in the workpiece.
h) Do not use the saw until the table is clear of all tools, wood scraps, etc., except for
the workpiece. Small debris or loose pieces of wood or other objects that contact the
revolving blade can be thrown with high speed.
i) Cut only one workpiece at a time. Stacked multiple workpieces cannot be adequately
clamped or braced and may bind on the blade or shift during cutting.
j) Ensure the mitre saw is mounted or placed on a level, firm work surface before use.
A level and firm work surface reduces the risk of the mitre saw becoming unstable.
k) Plan your work. Every time you change the bevel or mitre angle setting, make sure
the adjustable fence is set correctly to support the workpiece and will not interfere

IEC 62841-3-9:2014 © IEC 2014 – 11 –
with the blade or the guarding system. Without turning the tool “ON” and with no
workpiece on the table, move the saw blade through a complete simulated cut to assure
there will be no interference or danger of cutting the fence.
NOTE The phrase “bevel or” does not apply for saws without bevel adjustment.
l) Provide adequate support such as table extensions, saw horses, etc. for a
workpiece that is wider or longer than the table top. Workpieces longer or wider than
the mitre saw table can tip if not securely supported. If the cut-off piece or workpiece tips,
it can lift the lower guard or be thrown by the spinning blade.
m) Do not use another person as a substitute for a table extension or as additional
support. Unstable support for the workpiece can cause the blade to bind or the workpiece
to shift during the cutting operation pulling you and the helper into the spinning blade.
n) The cut-off piece must not be jammed or pressed by any means against the spinning
saw blade. If confined, i.e. using length stops, the cut-off piece could get wedged against
the blade and thrown violently.
o) Always use a clamp or a fixture designed to properly support round material such
as rods or tubing. Rods have a tendency to roll while being cut, causing the blade to
“bite” and pull the work with your hand into the blade.
p) Let the blade reach full speed before contacting the workpiece. This will reduce the
risk of the workpiece being thrown.
q) If the workpiece or blade becomes jammed, turn the mitre saw off. Wait for all
moving parts to stop and disconnect the plug from the power source and/or remove
the battery pack. Then work to free the jammed material. Continued sawing with a
jammed workpiece could cause loss of control or damage to the mitre saw.
r) After finishing the cut, release the switch, hold the saw head down and wait for the
blade to stop before removing the cut-off piece. Reaching with your hand near the
coasting blade is dangerous.
s) Hold the handle firmly when making an incomplete cut or when releasing the switch
before the saw head is completely in the down position. The braking action of the saw
may cause the saw head to be suddenly pulled downward, causing a risk of injury.
NOTE The above warning applies only for mitre saws with a brake system.
