EN ISO 11680-1 pdf download Machinery for forestry — Safety requirements and testing for pole‑mounted powered pruners — Part 1: Machines fitted with an integral combustion engine
This part of ISO 11680 gives safety requirements and measures for their verification for the designconstruction of portable, hand-held,pole-mounted powered pruners having an integral combustionengine astheir power unit and using a drive shaft to transmit power to a cutting attachment consisting of a saw chain a reciprocating or circular saw blade with a 205 mm maximum outside diameter.Methods for the eliminatioror reduction of hazards arising from the use of these machines and the type of information on safe workpractices to be provided by the manufacturer are specified.
This part of lISO 11680 deals with allsignificant hazards, hazardous situations or hazardous events with thexception of electric shock from contact with overhead electric lines (apart from warnings and adviceinclusion in the instruction handbook)， relevant to these machines when they are used as intended and underconditions of misuse which are reasonably foreseeable by the manufacturer.
NOTESee Annex A for a list of significant hazards.
This part of lSo 11680 is applicable to portable，hand-held，pole-mounted powered pruners manufactured afterits date of publication.

3 Terms and definitions
For the purpose of this document,the terms and definitions given in lISO 6531, ISO 7112 and ISO 12100 andthe following apply.
pole-mounted powered pruner
machine whose power source is attached via a long drive-shaft tube(pole) to a cutting attachment,designedto enable an operator to cut branches from a distance
NOTE See Figure 1 for an example of a pole-mounted powered pruner with integral combustion engine and a saw-chain cutting attachment within the Scope of this part of lsO 11680.
4 Safety requirements andor protective measures
Machines shall comply with the safety requirements and/or protective measures of this clause. In addition, themachine shall be designed according to the principles of lSo 12100 for relevant but not significant hazardswhich are not dealt with by this part of Iso 11680.
The safe operation of a pole-mounted powered pruner also depends on the safe environment associated withthe use of personal protective equipment (PPE) such as gloves,slip-resistant footwear，and eye, hearing andhead protective equipment，as well as safe working procedures (see 5.1).
Except where otherwise specified in this part of lSO 11680， the safety distances specified in IS0 138572008,126.96.36.199 and 188.8.131.52,shall be met.
The machine shall have a hand-grip for each hand. The shape and surface of the hand-grip shall be designedso as to provide the necessary sureness of grip，regardless of whether or not the operator wears gloves.lfthe hand-grip nearest the cutting attachment is an integral part of the drive-shaft tube, the diameter shall bebetween 20 mm and 50 mm. The hand-grip length shall be at least 100 mm.
The gripping length of a bail or closed hand-grip shall comprise any length that is straight or curved at a radiusgreater than 100 mm together with any blend radius, but not more than 10 mm, at one or both ends of thegripping surface.
The design and dimensions shall be verified by inspection and measurement.
