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 Key words: Hedge trimmer, Hand-held tool, Safety

Outils électroportatifs à moteur, outils portables et machines pour jardins et pelouses - Sécurité - Partie 4-2: Exigences particulières pour les taille-haies
IEC 62841-4-2:2017 s'applique aux taille-haies portatifs qui sont conçus pour être utilisés par un opérateur pour tailler les haies et les buissons, y compris les taille-haies télescopiques portatifs d’une longueur maximale de 3,5 m. La tension assignée est inférieure à 250 V pour les outils à courant monophasé alternatif ou continu, et inférieure à 480 V pour les outils à courant alternatif triphasé. La tension assignée est inférieure à 3 700 W. Les limites d'application de la présente Norme aux outils fonctionnant sur batterie sont indiquées en K.1 et L.1. La présente Norme traite des dangers présentés par les outils, encourus par tous les individus dans l'utilisation normale et dans l'utilisation impropre raisonnablement prévisible de ces outils. 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. La présente norme ne s'applique pas aux taille-haies avec une lame rotative. La présente norme ne s'applique pas aux cisailles à gazon de type ciseaux. La présente Partie 4-2 doit être utilisée conjointement avec la première édition de l'IEC 62841-1 (2014). 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 36 mois après la date de publication. Mots clés: taille-haies, outil portable, sécurité

Replace Note 103 with the following:
Except for Category 1 machines, this annex does not apply to hedge trimmers equipped with integral
batteries.
Replace the NOTE 101 in Subclause K.21.18 with the following:
K.21.18.Z101 Isolation and disabling device
Machines with an integral battery shall either be equipped
– with an isolation device to prevent the risk of injury from mechanical hazards during servicing or user
maintenance; or
– with a disabling device that prevents unintentional starting of the machine.
An isolation device shall
– provide disconnection of all poles of the battery from the serviceable region of the machine;
– be equipped with an unambiguous indication of the state of the disconnection device which
corresponds to each position of its manual control (actuator);
– be provided with protection against accidental reconnection.
NOTE 1 Examples of methods to achieve this disconnection include removable jumpers, integral batteries that can be
disconnected for servicing or user maintenance, or an electromechanical power switch with a direct mechanical link between the
actuator and the contact.
NOTE 2 The risk of accidental reconnection for a power switch is addressed by the requirement of 21.18.102.3. The other
examples in NOTE 1 achieve this by the necessary actions for reconnection.
A disabling device may be achieved by any of the following:
– a self-restoring or non-self-restoring lock-off device where two separate and dissimilar actions are
necessary before the motor is switched on (e.g. a power switch which has to be pushed in before it
can be moved laterally to close the contacts to start the motor). It shall not be possible to achieve
these two actions with a single grasping motion or a straight-line motion;
– a removable disabling device provided with the machine where it shall not be possible for the
