ISO 11680-1:2011 gives safety requirements and measures for their verification for the design and construction of portable, hand-held, pole-mounted powered pruners having an integral combustion engine as their power unit and using a drive shaft to transmit power to a cutting attachment consisting of a saw chain or a reciprocating or circular saw blade with a 205 mm maximum outside diameter. 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 11680-1:2011 deals with all significant hazards, hazardous situations or hazardous events with the exception of electric shock from contact with overhead electric lines (apart from warnings and advice for inclusion in the instruction handbook), relevant to these machines when they are used as intended and under conditions of misuse which are reasonably foreseeable by the manufacturer.
