This European Standard deals with all significant hazards, hazardous situations and events relevant to walk-behind trimmers, powered by a combustion engine, with cutting means using non-metallic filament line or freely pivoting non-metallic cutter(s), of which the cutting elements rely on centrifugal force to achieve cutting with the kinetic energy of a single cutting element not exceeding 10 J, designed for cutting grass or similar plant material, when they are used as intended and under conditions of misuse which are reasonably foreseeable by the manufacturer (see Clause 4).
This European Standard is not applicable to:
a) walk-behind trimmers with cutting means other than those described above
b) self propelled walk-behind trimmers or walk-behind edge trimmers
c) lawnmowers using non-metallic filament line or freely pivoting non-metallic cutting elements with greater than 10 J kinetic energy
NOTE 1 EN 836 applies for machines using non-metallic filament line or freely pivoting non-metallic cutting elements with greater than 10 J kinetic energy.
d) motor mowers using metal or other solid cutting elements.
NOTE 2 EN 12733 applies for machines using metal or other solid cutting elements.
EMC and environmental hazards other than noise have not been considered in this European Standard.
This European Standard is not applicable to walk-behind trimmers which are manufactured before the date of its publication as EN.
NOTE 3 Lawn trimmers and lawn edge trimmers (electric powered) are dealt with in EN 786, grass trimmers (internal combustion engine powered) are dealt with in EN 11806 and lawn mowers (internal combustion engine powered) are dealt with in EN 836.
