EN 17106-4:2021

This European Standard applies to machines used for road service area maintenance which are attached to or mounted on carrier vehicles (e.g. tractor, truck), or which are self-propelled machinery and which are defined in Clause 3. Directives and standards for the vehicular truck or tractor chassis aspect, termed 'carrier vehicle' in this standard, would be those relevant to that equipment.For machinery which are a combination of a grass/brush-cutting attachment and a carrier-vehicle, this part of the standard applies to the grass or brush cutting attachment itself and with all health and safety requirements of the interaction and effects between attachment and the carrier vehicle when used together (e.g. stability, visibility).For self-propelled machinery, this part only deals with health and safety requirements of the attachment itself and does not deal with the self-propelled machinery itself which are dealt with in EN 17106 1.NOTE 1Road regulations or Directive apply to vehicular truck and tractor.NOTE 2The use in public road traffic is governed by the national regulations.This European Standard deals with all significant hazards identified through a risk assessment pertinent to road service area maintenance machines, when they are used as intended and under the conditions foreseen by the manufacturer (see Clause 4). This European Standard does not deal with significant hazards associated with EMC. This European Standard specifies the appropriate technical measures to eliminate or reduce risks arising from the significant hazards associated with machine operation, setting and adjustments, load discharge and routine maintenance.This European Standard does not include requirements for the carrier vehicles (e.g. trucks, tractors, construction machines, industrial trucks). These are covered in directives related to the construction of vehicles.This European Standard does not deal with:—walker-operated and hand-held machines;—machines for the maintenance of sports grounds;—machines for agriculture, horticulture and forestry;—pit and sewer cleaning vehicles/-machines;—grass and brush cutting machines with multiple cutting heads (see Annex A, Clause C.2, Figure C.20)—vertical axis grass and brush cutting machines except inter-post machinery (see Annex A, Clause C.2, Figure C.22)—horizontal axis grass and brush cutting machines with two rotors (see Annex A, Clause C.2, Figure C.23)—self-propelled remote controlled machinery for road service area maintenance, except the mowing head—self-propelled remote controlled machinery used for forestry application (see Annex A, Clause C.2, Figure C.21)—cleansing and ditch maintenance machines (see Annex A, Clause C.2, Figure C.24 and C.25)A machine which is a combination of several parts with different uses should conform to all the standards referring to the corresponding parts of the machine.This document, together with part 1, deals with all significant hazards for road service area maintenance machines – grass and brush cutting machines when they are used as intended and under the conditions of misuse which are reasonably foreseeable by the manufacturer associated with the whole life time of the machine (see Clause 4).The requirements of this part are complementary to the common requirements formulated in prEN 17106 1:2017.This document does not repeat the requirements from prEN 17106 1:2017, but adds or replaces the requirements for application for grass and brush cutting machines.This European Standard does not deal with the risks associated with the operation of machines in potentially explosive atmospheres.This standard applies to machines manufactured after the date of approval of this standard through CEN.
