Scope

This part of ISO 11806 gives safety requirements and measures for their verification for the design
and construction of portable, hand-held, powered brush-cutters and grass-trimmers with a back-packmounted
combustion engine power source 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 part of ISO 11806, taken together with the relevant clauses of ISO 11806-1 (see 4.1), deals with
all significant hazards, hazardous situations and hazardous events, with the exception of whole-body
vibration from the back-pack power unit, relevant to these machines when they are used as intended
and under conditions of misuse which are reasonably foreseeable by the manufacturer.
NOTE 1 – A standardized test procedure for measuring whole-body vibration from the back-pack power unit is
presently not available.
NOTE 2 – See Annex A, together with Annex A in ISO 11806-1:2020, for a list of significant hazards.
This part of ISO 11806 is applicable to portable, hand-held, powered brush-cutters and grass-trimmers
manufactured after its date of publication.
This part of ISO 11806 is not applicable to machines equipped with metallic cutting attachments
consisting of more than one piece, e.g. pivoting chains or flail blades.
