Scope
This European Standard specifies mechanical safety requirements and testing for the design and construction of electrically powered walk-behind and hand-held lawn trimmers and lawn edge trimmers, with cutting element(s) of non-metallic filament line or freely pivoting non-metallic cutter(s) with a kinetic energy of not more that 10 J each, and used by a standing operator primarily for cutting grass. It describes methods for the elimination or reduction of hazards arising from their use. In addition, it specifies the type of information to be provided by the manufacturer on safe working practices. This standard is not applicable to: a) Scissor type or lawn trimmers and lawn edge trimmers with cutting means other than those described above; b) Self-propelled lawn trimmers or lawn edge trimmers; c) Lawn trimmers or lawn edge trimmers which do not have a distance of at least 600 mm between the cutting means control and the cutting head. The electrical aspects of electrically powered lawn trimmers and lawn edge trimmers are not covered by this standard. The list of significant hazards dealt with in this standard is given in annex A. Annex A also indicates the hazards which have not been dealt with. Environmental aspects have not been considered in this standard. This European Standard applies primarily to machines which are manufactured after the date of issue of this standard. NOTE The method of calculating the kinetic energy for the purposes of this standard is given in annex B.
