ISO 11806-2:2011 gives safety requirements and measures for their verification for the design and construction of portable, hand-held, powered brush-cutters and grass-trimmers with a back-pack-mounted combustion engine power source and mechanical power transmission between the power source and the cutting attachment. 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.ISO 11806-2:2011 is not applicable to lawn-edge trimmers or to brush-cutters equipped with metallic blades consisting of more than one part, e.g. pivoting chain.ISO 11806-2:2011, taken together with the relevant clauses of ISO 11806-1, deals with all significant hazards, hazardous situations and hazardous events, with the exception of whole-body vibration from the back-pack power unit, relevant to these machines when they are used as intended and under conditions of misuse which are reasonably foreseeable by the manufacturer.

Le présent document détermine les prescriptions de sécurité et les vérifications pour la conception et la construction des sources motrices portées à dos comprenant un moteur à combustion interne comme source de puissance et utilisées pour alimenter une variété d'appareils.
Le présent document détermine les prescriptions de sécurité et les vérifications pour la conception et la construction des débroussailleuses et coupe-herbe portatifs équipés d'une source motrice, portée à dos, à moteur thermique. L'attention du lecteur est attirée sur le fait que ces machines doivent répondre aux exigences de la Directive Machines (89/392/CEE modifiée par les Directives 91/368/CEE, 93/44/CEE et 93/68/CEE) qui leur sont applicable.
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.
