本文件规定了便携式、手持式、杆装式动力修剪机（以下简称“机器”）的设计和建造的安全要求和验证措施，包括可伸缩和可伸缩机器，其动力源为一体式内燃机。这些机器使用动力传动轴将动力传输至切割附件，切割附件由锯链和导杆、往复式锯片或最大外径为205？mm的单件圆形锯片组成。规定了消除或减少因使用这些机器而产生的危险的方法，以及制造商提供的有关安全工作实践的信息类型。 本文件涉及与这些机器有关的所有重大危险、危险情况或危险事件，但因接触架空电线而触电的情况除外（除了说明中包含的警告和建议），当这些机器按预期使用时，以及在制造商可合理预见的误用情况下（见附录A）。 本文件适用于出版日期后制造的便携式、手持式、杆装式动力修剪机。 带圆锯片的刷子刀具不包括在本文件的范围内。 注？ISO？11806-1:2021概述了电刷切割机的要求。

This document specifies safety requirements and measures for their verification for the design and construction of portable, hand-held, pole-mounted powered pruners (hereafter named “machine”), including extendable and telescopic machines, having an integral combustion engine as their power source. These machines use a power transmission shaft to transmit power to a cutting attachment consisting of a saw-chain and guide bar, a reciprocating saw blade or a single-piece 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. This document 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 instructions), relevant to these machines when they are used as intended and under conditions of misuse which are reasonably foreseeable by the manufacturer (see Annex？A). This document is applicable to portable, hand-held, pole-mounted powered pruners manufactured after its date of publication. Brush cutters with a circular saw blade are not included in the scope of this document. NOTE？Brush cutter requirements are outlined in ISO？11806-1:2021.
