Garden equipment - Walk-behind combustion engine powered trimmers - Safety
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;

EN 14910:2007+A1:2009 - Garden equipment: Walk-behind combustion engine powered trimmers - Safety
Overview
EN 14910:2007+A1:2009 is a CEN European Standard that specifies safety requirements for walk‑behind trimmers powered by combustion engines designed to cut grass or similar plant material using non‑metallic filament line or freely pivoting non‑metallic cutters. The standard covers significant hazards when the equipment is used as intended and under reasonably foreseeable misuse. It includes Amendment 1 (2009) and supports compliance with relevant EU machinery directives.
Scope highlights
- Applies to walk‑behind combustion engine trimmers whose single cutting element kinetic energy does not exceed 10 J.
- Excludes self‑propelled trimmers, edge trimmers, machines with other cutting means, and machines manufactured before the EN publication date.
- EMC and environmental hazards other than noise are not considered in this standard.
Key topics and technical requirements
The standard addresses hazards through design, testing and documentation. Major sections include:
- Guards and guarding (power‑driven components, cutting‑means guards, hot surfaces)
- Controls and starting/stopping - safe operation and engine stop/start requirements
- Electrical requirements for battery and ignition circuits (cables, terminals, overload protection)
- Cutting means - limits tied to kinetic energy, construction and marking of cutting heads
- Mechanical strength and rigidity - structural integrity of guards and cutting heads
- Vibration and noise - measurement methods, reduction by design and information to users (Annex A: vibration; Annex B: noise test code)
- Fuel and fluid safety - tank openings, liquid spillage, exhaust protection
- Information for use - instructions, markings, warnings, and durability of markings (Annexes E–F include safety signs and user safety instructions)
- Verification methods - test procedures and calculation methods (e.g., kinetic energy calculation in Annex D)
Practical applications and users
EN 14910 is used by:
- Manufacturers and designers to develop compliant walk‑behind trimmers and integrate guards, controls and safety features.
- Test laboratories and conformity assessors for type testing, noise and vibration measurement, and CE conformity documentation.
- Safety engineers and technical writers preparing user manuals, warning labels and maintenance procedures.
- Procurement teams and regulators evaluating product safety and compliance with EU machinery directives.
Typical uses:
- Product development risk assessment and safety validation
- Preparing instructions for use, marking and warning labels
- Verifying noise/vibration performance and mechanical robustness
Related standards
- EN 836 - machines using non‑metallic cutting elements with kinetic energy > 10 J
- EN 12733 - motor mowers with metal/solid cutting elements
- EN 786 - electric lawn trimmers and edge trimmers
- EN 11806 - internal combustion engine powered grass trimmers
This standard is essential for stakeholders involved in the safe design, testing and sale of walk‑behind combustion engine trimmers in the European market.
