ÖNORM EN ISO 11806-2

This part of ISO 11806 specifies safety requirements and their verification for design and construction of portable handheld, combustion engine driven brush-cutters and grass-trimmers having a backpack mounted combustion engine power source and mechanical power transmission between power source and cutting attachment. This Standard 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. It describes methods for the elimination or reduction of hazards arising from their use. In addition it specifies the type of information on safe working practices to be provided by the manufacturer. This document deals, except for whole body vibration hazard from the backpack power unit with all significant hazards, hazardous situations or hazardous events relevant to these machines, when they are used as intended and under conditions of reasonably foreseeable misuse.
