DIN EN ISO 11806-2:2012-04

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 source and cutting attachment. This standard does not apply for lawn edge trimmers or brush-cutters equipped with metallic blades consisting of more than one part, e. g. pivoting chains. 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 providedby 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.
