Bibliography

This document deals with the significant hazards, hazardous situations and events as listed in Clause 4 which are relevant to stationary and displaceable circular saw benches (with or without sliding table and/or demountable power feed unit), dimensions saws and building site saws, hereinafter referred to as “machines”, designed to cut solid wood, chipboard, fibreboard, plywood and also these materials, if 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.NOTE 1For the definition of stationary and displaceable machine see 3.13 and 3.14.NOTE 2Circular saw benches, and dimension saws are used for ripping, cross cutting, dimensioning and grooving. Building site saws are used for ripping, cross cutting and dimensioning.The requirements of this document apply also to machines designed for grooving with a width not exceeding 20 mm in one pass by using a milling tool.This document does not apply to:a)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. The bench can also be an integrated part of the machine if it consists of hinged legs which can be extended down;b)hand held woodworking machines including any adaptation permitting their use in a different mode, i.e. bench mounting.NOTE 3Transportable motor-operated electric tools are covered by the requirements of EN 61029-1:2000 together with EN 61029-2-1:2002; 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 60745-1:2003 together with EN 60745-2-5:2003.For the purpose of this document building site saws having a tiltable spindle are considered to be circular saw benches.This document is not applicable to circular saw benches (with and without sliding table), dimensions saws and b
