This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by May 2015, and conflicting national standards shall be withdrawn at the latest by May 2015. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN [and/or CENELEC] shall not be held responsible for identifying any or all such patent rights. This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association, and supports essential requirements of EU Directive(s). For relationship with EU Directive(s), see informative Annex ZA, which is an integral part of this document. The main modifications compared to EN 1870-3:2001+A1:2009 relate to the introduction of performance levels (PL) for control systems and to the following items: — clarification of controls positions in 5.2.2; — addition of PL where missing; — addition of requirements on mode selection in 5.2.7 and on prevention of automatic restart in 5.2.8; — deletion of material requirements on flanges in 5.3.3.3; — addition of requirements on braking system in 5.3.4; — up-date of references; — addition of requirements in 5.4.3 on chips and dust performances; — limitation of tightening torque for riving knife mounting screws in Annex B.

BS EN 1870-3:2014 EN 1870-3:2014 (E) 6 Introduction This document has been prepared to be a harmonized standard to provide one means of conforming to the essential safety requirements of the Machinery Directive, and associated EFTA regulations. This European Standard is a type “C” standard as defined in EN ISO 12100:2010. The extent to which hazards are covered is 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 other standards, for machines that have been designed and built according to the provisions of this type C standard. The requirements of this document are directed to manufacturers and their authorized representatives of down cutting cross-cut saws and dual purpose down cutting cross -cut saws/circular saw benches. They are also useful for designers. This document also includes information to be provided by the manufacturer to the user. Common requirements for tooling are given in EN 847-1:2013. Electrically driven machines excluded by the scope of this document are covered by the requirements of EN 61029-1:2000, EN 61029-2-9:2009 and EN 61029-2-11:2009. BS EN 1870-3:2014 EN 1870-3:2014 (E) 7 1 Scope This European Standard deals with all significant hazards, hazardous situations and events as listed in Clause 4 which are relevant to down cutting cross-cut saws and dual purpose down cutting cross-cut saws/circular saw benches, herein after referred to as “machines”, designed to cut solid wood, chipboard, fibreboard, plywood and also these materials where they are covered with plastic edging and/or plastic/light alloy laminates when they are used as intended and under the conditions foreseen by the manufacturer including reasonably foreseeable misuse. NOTE 1 For the definition of down cutting cross-cut saws and dual purpose down cutting cross -cut saws/circular saw benches, see 3.2.2, 3.2.3 and 3.2.4, and for the definition of displaceable machine, see 3.2.8. This document does not apply to: — machines for cross cutting logs; — hand-held motor-operated electric tools or any adaptation permitting their use in a different mode, e.g. bench mounting; NOTE 2 Hand-held motor-operated electric tools and saw benches to form an integrated whole with a hand-held motor- operated electric tools are covered by EN 60745-1:2009 together with EN 60745-2–5:2010. — transportable machines set up on a bench or a table similar to a bench, which are intended to carry out work in a stationary position, capable of being lifted by one person by hand i.e. maximum mass ≤ 25 kg. NOTE 3 Transportable motor-operated electric tools are covered by the requirements of EN 61029-1:2009 together with EN 61029-2–9:2009 and EN 61029-2–11:2009. This document is not applicable to down cutting cross-cut saws and dual purpose down cutting cross-cut saws/circular saw benches which are manufactured before the date of its publication as European Standard. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
