This document is a type C standard as stated in EN 1070
The machinery concerned and the extent to which hazards, hazardous situations and events are covered are indicated in the scope of this document
When provisions of this type C standard are different from those which are stated in type A or B standards, the provisions of this type C standard take precedence over the provisions of the other standards, for machines that have been designed and built according to the provisions of this type C standard
Trang 81 Scope
This European Standard specifies safety requirements and their verification for the design and construction of pedestrian controlled integrally powered lawn aerators and scarifiers which are designed for re-generating lawns by, for instance, combing out grass, thatch and moss or cutting vertically into the lawn face using tines which rotate about a horizontal axis It describes methods of 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
Throughout this standard, the term “machine” applies to those machines known as aerators, scarifiers, corers, lawn rakes or grass rakes
This standard does not apply to aerators/scarifiers made from a machine falling within the scope of
EN 709:1997 when fitted with an aerating/scarifying implement, non-powered aerators, vertical axis aerators or those aerators which cut into the soil by means of a reciprocating motion or by water pressure The electrical aspects of mains operated machines are covered by EN 60335-1 The safety aspects of batteries other than batteries for starting the engine and the electrical safety aspects of battery powered lawn aerators and scarifiers are not covered by this standard
This standard deals with all significant hazards, hazardous situations and events relevant to scarifiers and aerators, when they are used as intended and under the conditions foreseen by the manufacturer (see Clause 4)
Environmental hazards and EMC have not been considered in this standard
This document is not applicable to aerators/scarifiers which are manufactured before the date of publication of this document by CEN
