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. 2 Normative references The following referenced documents are indispensable for the application of this European Standard.

In addition, the trimmer shall be designed according to the principles of EN ISO 12100 for relevant but not significant hazards, which are not dealt with by this European Standard. 5.2 Guards 5.2.1 General It shall not be possible to fit or adjust any guard required by this European Standard so that it does not comply with the requirements of this European Standard. Compliance shall be checked by inspection. 5.2.2 Power driven components (other than the cutting means) All power driven transmission parts shall be guarded to prevent the operator's contact with these parts. All guards required by this European Standard shall be fixed guards as defined in 3.25.1 of EN 12100-1:2003 or the construction of the trimmer shall be such that it cannot be used without the guard in its guarding position as defined in 3.25.4 of EN 12100-1:2003. All apertures and safety distances shall conform to 4.5.1, 4.5.3 and Table 4 of EN 294:1992. Compliance shall be checked by inspection.
