本文件规定了安全技术要求和措施，以确定便携式手持式高压油轮（以下简称“机械”）的设计和建造是否符合要求，该油轮采用集成内燃机作为推进装置，包括可再生和伸缩机械。这些机器配备有一个驱动轴，用于将动力传输至切割机，该驱动轴由链锯、移动锯片或最大外径为205 mm的圆锯片组成。应规定防止或减少因使用这些机器而产生的风险的方法以及制造商提供的安全工作信息。 本文件涵盖这些机器的所有重大危险、危险情况或危险事件，但因接触高电流架空接触线而触电的情况除外（使用说明中的警告和说明除外），前提是它们用于预期目的，并且在制造商可预见的合理误用情况下（见附录A）。 本文件适用于本标准发布日期后制造的便携式、手持式、高速电机柴油机。 带圆锯片的自由切割机不在本文件范围内。 注:ISO 11806中规定了自由职业者的要求- 1:2021描述。

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.
