Electric motor-operated hand-held tools, transportable tools and lawn and garden machinery - Safety - Part 4-2: Particular requirements for hedge trimmers
IEC 62841-4-2:2017 applies to hand-held hedge trimmers which are designed for use by one operator for trimming hedges and bushes, including extended-reach hedge trimmers with a maximum length of 3,5 m. 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 are given in K.1 and L.1. 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.
This standard is not applicable to hedge trimmers with a rotating blade.
This standard is not applicable to scissors type grass shears.
This Part 4-2 is to be used in conjunction with the first edition of IEC 62841-1:2014.
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
The contents of the corrigendum of June 2018 have been included in this copy.
Key words: Hedge trimmer, Hand-held tool, Safety

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.

8.14.1 Addition:
The additional safety instructions as specified in 8.14.1.101 shall be given for all hedge
trimmers. The additional safety instructions as specified in 8.14.1.102 shall be given for all
extended-reach hedge trimmers. This part may be printed separately from the “General
Machine Safety Warnings”.
NOTE 101 “General Machine Safety Warnings” are referred to as “General Power Tool Safety Warnings” in Part 1.
8.14.1.101 Safety instructions for hedge trimmers
Hedge trimmer safety warnings:
a) Keep all parts of the body away from the blade. Do not remove cut material or hold
material to be cut when blades are moving. Blades continue to move after the switch is
turned off. A moment of inattention while operating the hedge trimmer may result in
serious personal injury.
b) Carry the hedge trimmer by the handle with the blade stopped and taking care not to
operate any power switch. Proper carrying of the hedge trimmer will decrease the risk of
inadvertent starting and resultant personal injury from the blades.
c) When transporting or storing the hedge trimmer, always fit the blade cover. Proper
handling of the hedge trimmer will decrease the risk of personal injury from the blades.
d) When clearing jammed material or servicing the unit, make sure all power switches
are off and the power cord is disconnected. Unexpected actuation of the hedge trimmer
while clearing jammed material or servicing may result in serious personal injury.
e) Hold the hedge trimmer by insulated gripping surfaces only, because the blade may
contact hidden wiring or its own cord. Blades contacting a "live" wire may make
exposed metal parts of the hedge trimmer "live" and could give the operator an electric
shock.
f) Keep all power cords and cables away from cutting area. Power cords or cables may
be hidden in hedges or bushes and can be accidentally cut by the blade.
g) Do not use the hedge trimmer in bad weather conditions, especially when there is a
risk of lightning. This decreases the risk of being struck by lightning.
8.14.1.102 Additional safety instructions for extended-reach hedge trimmers
Extended-reach hedge trimmer safety warnings:
a) To reduce the risk of electrocution, never use the extended-reach hedge trimmer
near any electrical power lines. Contact with or use near power lines may cause serious
injury or electric shock resulting in death.
b) Always use two hands when operating the extended-reach hedge trimmer. Hold the
extended-reach hedge trimmer with both hands to avoid loss of control.
c) Always use head protection when operating the extended-reach hedge trimmer
overhead. Falling debris can result in serious personal injury.
NOTE Alternate wording for "extended-reach" is possible, e.g. “pole” or “long reach”.
8.14.2 a) Addition:
101) If applicable, information on cutting devices and attachments permitted to be used
with the hedge trimmer, e.g. a device attached to the cutting device to aid removal of

19.101 Handles
19.101.1 Hedge trimmer handles
19.101.1.1 General
For all hedge trimmers except for extended-reach hedge trimmers, the minimum number of
handles shall be in accordance with Table 101.
If a part containing the motor complies with the dimensions for a handle, it may be considered
as a handle.
The handles shall be designed in such a way that each one can be grasped with one hand.
Handles shall be suitably shaped to be grasped securely and have a perimeter between
65 mm and 170 mm as illustrated in Figure 105 a), 105 b) or 105 c). The perimeter is
determined by a chain measurement with the blade control, if any, fully depressed. The
gripping length of the handle(s) shall be at least 100 mm long.
If applicable, the part of the handle containing the blade control shall be counted as part of
the handle gripping length.
If there are finger grips or similar superimposed profiles, the handle gripping length shall not
be measured along the surface, but only the arc or straight line distance of the gripping
surface, as applicable, shall be taken into account.
Handles shall be locked in position during operation except as allowed by 19.101.3. If they
are adjustable without tools to different positions in accordance with 8.14.2 b), it shall not be
possible to operate the machine when adjusted to a position which contravenes other
provisions of this standard.
NOTE The requirements for endurance and integrity of adjustments are covered in 19.107 and 19.108.
Compliance is checked by inspection and by measurements.
19.101.1.2 Dimensions of bail or closed handles
On bail or closed handles (U-shaped handles) the gripping length is related to the inner width
of the gripping surface. There shall be a minimum radial clearance of 25 mm around the
gripping length.
If a bail or closed handle is used, the gripping length L in Figure 105 a) shall be measured
using lengths A and B as follows:
– the length A is measured within region X where the radius is at least 100 mm;
– the length(s) B are measured within region(s) Y where the transition radius is less than
100 mm, but each length B cannot exceed 10 mm in each region Y of the gripping surface.
Compliance is checked by inspection and by measurements.
19.101.1.3 Dimensions of handles supported centrally (T–type)
If a handle is supported centrally (i.e. T-type), there shall be a minimum radial clearance of
25 mm around the gripping length. The gripping length shall be calculated as follows (see
Figure 105 b)):
– for handles with a perimeter P (not including the support) of less than 80 mm, the gripping
length is the sum of the two parts of the gripping length X + Y on either side of the
support;
– for handles with a perimeter P (not including the support) of 80 mm or more, the gripping
length is the complete length Z from end to end.
Compliance is checked by inspection and by measurements.
19.101.1.4 Dimensions of handles that are formed by the shaft
The gripping length L in Figure 105 c) shall be measured using the straight portion of the
handle, not including any transition radius, finger grips or similar superimposed profiles.
Compliance is checked by inspection and by measurements.
– 16 – IEC 62841-4-2:2017 © IEC 2017
19.101.2 Extended-reach hedge trimmer handles
19.101.2.1 General
For extended-reach hedge trimmers, the minimum number of handles shall be in
accordance with Table 102.
If a part containing the motor complies with the dimensions for a handle, it may be considered
as a handle.
A shaft may be used as a handle if specified in accordance with 8.14.2.
The handles shall be designed in such a way that each one can be grasped with one hand.
Handles shall be suitably shaped to be grasped securely and have a perimeter P between
65 mm and 170 mm as illustrated in Figure 105 a), 105 b) or 105 c). The perimeter P is
determined by a chain measurement with the blade control, if any, fully depressed. The
gripping length of the front handle and the rear handle shall be at least 100 mm long.
If applicable, the part of the handle containing the blade control shall be counted as part of
the handle gripping length.
If there are finger grips or similar superimposed profiles, the handle gripping length shall not
be measured along the surface, but only the arc or straight line distance of the gripping
surface, as applicable, shall be taken into account.
If handles are adjustable to different positions without tools in accordance with 8.14.2 b), it
shall not be possible to inadvertently operate the machine when locked in a position which
contravenes other provisions of this standard. This may be achieved by at least one blade
control requiring two separate and dissimilar actions before the cutting device operates as
described in

Part 4-2: Particular requirements for hedge trimmers
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.
This consolidated version of the official IEC Standard and its amendment has been
prepared for user convenience.
IEC 62841-4-2 edition 1.1 contains the first edition (2017-12) [documents 116/346/FDIS
and 116/352/RVD], its corrigendum (2018-06) and its amendment 1 (2022-05) [documents
116/578/FDIS and 116/586/RVD].

International Standard IEC 62841-4-2 has been prepared by IEC technical committee 116:
Safety of motor-operated electric tools.
This document has been drafted in accordance with the ISO/IEC Directives, Part 2.
This Part 4-2 is to be used in conjunction with the first edition of IEC 62841-1 (2014).
This Part 4-2 supplements or modifies the corresponding clauses in IEC 62841-1, so as to
convert it into the IEC Standard: Particular requirements for hedge trimmers.
Where a particular subclause of Part 1 is not mentioned in this Part 4-2, that subclause
applies as far as relevant. 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, tables and figures which are additional to those in Part 1, except as
described for Annex K and Annex L below, are numbered starting from 101.
Subclauses, notes, tables and figures in Annex K and Annex L which are additional to those in
the main body of this Part 4-2 as well as Annex K and Annex L of Part 1 are numbered
starting from 301.
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 the base publication and its amendment will
remain unchanged until the stability date indicated on the IEC web site under 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.
IMPORTANT – The "colour inside" logo on the cover page of this document indicates
that it contains colours which are considered to be useful for the correct
understanding of its contents. Users should therefore print this document using a

8.14.1.101 Safety instructions for hedge trimmers
For Category 1 hedge trimmers that can be converted to a grass shear, the term "hedge
trimmer" may be replaced by alternate wording (e.g. "grass shear/hedge trimmer" or "grass
shear/shrub shear"). For this case, the verbatim warnings below need not be repeated for the
two configurations.
Hedge trimmer safety warnings:
a) Keep all parts of the body away from the blade. Do not remove cut material or hold
material to be cut when blades are moving. Blades continue to move after the switch is
turned off. A moment of inattention while operating the hedge trimmer may result in
serious personal injury.
b) Carry the hedge trimmer by the handle with the blade stopped and taking care not to
operate any power switch. Proper carrying of the hedge trimmer will decrease the risk of
inadvertent starting and resultant personal injury from the blades.
c) When transporting or storing the hedge trimmer, always fit the blade cover. Proper
handling of the hedge trimmer will decrease the risk of personal injury from the blades.
d) When clearing jammed material or servicing the unit, make sure all power switches
are off and the power cord is disconnected. Unexpected actuation of the hedge trimmer
while clearing jammed material or servicing may result in serious personal injury.

e) Hold the hedge trimmer by insulated gripping surfaces only, because the blade may
contact hidden wiring or its own cord. Blades contacting a "live" wire may make
exposed metal parts of the hedge trimmer "live" and could give the operator an electric
shock.
f) Keep all power cords and cables away from cutting area. Power cords or cables may
be hidden in hedges or bushes and can be accidentally cut by the blade.
g) Do not use the hedge trimmer in bad weather conditions, especially when there is a
risk of lightning. This decreases the risk of being struck by lightning.
