This document specifies safety requirements, and measures for their verification, for the design and construction of portable, hand-held, powered brush-cutters and grass-trimmers with a backpack-mounted combustion engine power source and mechanical power transmission between the power source and the cutting attachment (hereafter referred to as “machine”). Methods for the elimination or reduction of hazards arising from the use of these machines and the type of information on safe working practices to be provided by the manufacturer are specified.
This document, taken together with the relevant clauses of ISO 11806-1:2021 (see 4.1), deals with all significant hazards, hazardous situations and hazardous events, with the exception of whole-body vibration from the backpack power unit, relevant to these machines when they are used as intended and under conditions of misuse which are reasonably foreseeable by the manufacturer.
NOTE 1    A standardized test procedure for measuring whole-body vibration from the backpack power unit is not available at the time of publication.
NOTE 2    See Annex A, together with ISO 11806-1:2021, Annex A, for a list of significant hazards.
This document is applicable to portable, hand-held, powered brush-cutters and grass-trimmers manufactured after its date of publication.
This document is not applicable to machines equipped with metallic cutting attachments consisting of more than one piece, such as pivoting chains or flail blades.

Dieses Dokument legt sicherheitstechnische Anforderungen sowie Maßnahmen zu deren Überprüfung für die Gestaltung und Konstruktion von tragbaren, handgehaltenen, motorbetriebenen Freischneidern und Grastrimmern mit rückentragbarer verbrennungsmotorisch betriebener Antriebseinheit und mechani¬scher Kraftübertragung zwischen der Antriebseinheit und der Schneidgarnitur (im Folgenden „Maschine“ genannt) fest. Verfahren für die Beseitigung oder Verringerung von Gefährdungen, die durch den Einsatz dieser Maschinen entstehen, sowie die Art der Informationen für sichere Arbeitsweisen, die vom Hersteller zur Verfügung zu stellen sind, werden festgelegt.
Dieses Dokument, zusammen mit den relevanten Abschnitten von ISO 11806-1:2022 (siehe 4.1), behandelt alle signifikanten Gefährdungen, Gefährdungssituationen oder Gefährdungsereignisse, mit Ausnahme der von der rückentragbaren Antriebseinheit ausgehenden Ganzkörperschwingungen, die für diese Maschinen relevant sind, sofern sie zu dem vorgesehenen Zweck und bei vernünftigerweise durch den Hersteller vorhersehbarem Missbrauch eingesetzt werden.
ANMERKUNG 1   Ein standardisiertes Prüfverfahren zur Messung der Ganzkörperschwingungen, die von der rückentragbaren Antriebseinheit ausgehen, ist zum Ausgabedatum nicht verfügbar.
ANMERKUNG 2   Siehe Anhang A, zusammen mit ISO 11806-1:2022, Anhang A, zur Liste der signifikanten Gefährdungen.
Dieses Dokument ist anzuwenden für tragbare handgehaltene motorbetriebene Freischneider und Grastrimmer, die nach dessen Ausgabedatum hergestellt worden sind.
Dieses Dokument ist nicht anzuwenden für Maschinen, die mit mehrteiligen, metallischen Schneidgarnituren wie schwenkbaren Ketten oder Schlegelmessern ausgestattet sind.

Matériel agricole et forestier - Exigences de sécurité et essais pour débroussailleuses et coupe-herbe portatifs à moteur - Partie 2: Machines pour utilisation avec source motrice portée à dos (ISO 11806-2:2022, Version corrigée 2022-04)

Le présent document spécifie les exigences de sécurité et les mesures de protection pour leur vérification, pour la conception et la construction des débroussailleuses et des coupe-herbe portatifs à moteur, tenus à la main, équipés d’une source motrice à moteur à combustion interne, portée à dos, et d’une transmission mécanique de puissance entre la source motrice et le dispositif de coupe (appelés «machines» dans la suite du texte). Il spécifie des méthodes pour éliminer ou réduire les phénomènes dangereux inhérents à l’utilisation de ces machines et le type d’informations devant être fournies par le fabricant sur les pratiques d’utilisation sûre.
Le présent document, conjointement avec les articles pertinents de l’ISO 11806‑1:2021 (voir 4.1), traite de tous les phénomènes dangereux, situations dangereuses et événements dangereux significatifs, à l’exception des vibrations transmises à l’ensemble du corps par la source motrice portée à dos, pertinents pour ces machines lorsqu’elles sont utilisées normalement et dans des conditions de mauvais usage raisonnablement prévisibles par le fabricant.
NOTE 1        Aucune méthode d’essai normalisée permettant de mesurer les vibrations transmises à l’ensemble du corps par la source motrice portée à dos n’est actuellement disponible au moment de la publicaion.
NOTE 2        Pour la liste des phénomènes dangereux significatifs, voir l’Annexe A ainsi que l’ISO 11806‑1:2021, Annexe A.
Le présent document est applicable aux débroussailleuses et aux coupe-herbe portatifs à moteur tenus à la main fabriqués après sa date de publication.
Le présent document n’est pas applicable aux machines équipées de dispositifs de coupe métalliques constitués de plusieurs pièces, comme les chaînes articulées ou les lames à fléau.

Ta dokument določa varnostne zahteve in ukrepe za njihovo preverjanje za načrtovanje ter izdelavo prenosnih, ročno vodenih kosilnic s prosto rezjo, opremljenih z rezilno ploščo ali kosilno nitko, z nahrbtnim motornim pogonom z notranjim izgorevanjem ter mehanskim prenosom napajanja med virom napajanja in nastavkom za rezanje (v nadaljevanju: »stroji«). Predpisane so metode za odpravljanje ali zmanjšanje tveganj, ki izhajajo iz uporabe teh strojev, in vrsta informacij o varnih delovnih praksah, ki jih mora zagotoviti proizvajalec. Ta dokument poleg ustreznih točk standarda ISO 11806-1:2021 (glej točko 4.1) obravnava vsa večja tveganja, nevarne situacije ali nevarne dogodke v zvezi s temi stroji, razen vibriranja celotnega telesa zaradi nahrbtnega motornega pogona, kadar se uporabljajo v skladu s predvidenim namenom in pod pogoji pričakovane nepravilne uporabe, ki jih določa proizvajalec. OPOMBA 1: V času objave dokumenta standardiziran preskusni postopek za merjenje vibracij celotnega telesa zaradi nahrbtnega motornega pogona ni na voljo. OPOMBA 2: Za seznam večjih tveganj glej dodatek A tega dokumenta in dodatek A standarda ISO 11806-1:2021. Ta dokument se uporablja za prenosne, ročno vodene kosilnice s prosto rezjo, opremljene z rezilno ploščo ali kosilno nitko, izdelane po datumu njegove izdaje. Ta dokument se ne uporablja za stroje, opremljene s kovinskimi nastavki za rezanje, ki jih sestavlja več delov, npr. vrteče se verige ali mlatilne lopatice.
