ISO 11806-1:2022 pdf download.Agricultural and forestry machinery — Safety requirements and testing for portable, hand-held, powered brush-cutters and grass- trimmers — Part 1: Machines fitted with an integral combustion engine
This document gives safety requirements and measures for their verification for the design and construction of portable hand-held, powered brush-cutters and grass-trimmers (hereafter called machines) having an integral combustion engine as their power unit and mechanical power transmission between the power source and the cutting attachment. 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 and hazardous events relevant to these machines, as well as when they are used as intended and under conditions of misuse which are reasonably foreseeable by the manufacturer.
This document is not applicable to machines equipped with metallic cutting attachments consisting of more than one piece, such as pivoting chains or flail blades.
NOTE See Annex C for a list of significant hazards.
This document is applicable to portable, hand-held, powered brush-cutters and grass-trimmers manufactured after its date of publication.

3.1 machine
complete brush-cutter, brush saw or grass-trimmer, including power unit, drive shaft tube, cutting attachment and guard, but excluding the harness
4 Safety requirements and/or protective measures
4.1 General
Machines shall comply with the safety requirements and/or protective measures of this clause. In addition, the machine shall be designed according to the principles of ISO 12100:2010 for relevant but not significant hazards which are not dealt with by this document. The machine shall also be marked according to 5.2 and carry warnings according to 5.3.
The safe operation of a brush-cutter and a grass-trimmer depends on both the safety requirements given in this clause and the safe working conditions associated with the use of adequate personal protection equipment (PPE), such as gloves, slip-resistant footwear, and leg, eye and hearing protection equipment, as well as safe working procedures (see 5.1).ISO 11806-1 pdf download.ISO 11806-1 pdf download
