This Technical Specification gives safety requirements, and the means of verifying them, for the design and
construction of guards, only able to be opened with a tool, which are used to guard the moving parts of the
power transmission of self-propelled ride-on machines and mounted, semi-mounted or trailed machines used
in agriculture. In addition, it specifies the type of information on safe working practices (including residual
risks) to be provided by the manufacturer.
It deals with the significant hazards (as listed in Annex A), hazardous situations and events relevant to guards
of moving parts of power transmission used as intended and under the conditions foreseen by the
manufacturer (see Clauses 4 and 5).
It is not applicable to guards for moving parts of the power transmission of
- tractors,
- aircraft,
- air cushion vehicles, or
- lawn and garden equipment.
