This European Standard applies to transportable masonry and stone cutting-off machines stationary during work, principally used on job site building construction for cutting-off stones, other mineral construction materials and composite materials having at least one supporting surface. The power for the tool rotation is supplied by electrical or internal combustion prime motor. This European Standard deals with all significant hazards pertinent to masonry and stone cutting-off machines for job site (see clause 4), when they are used as intended and under the conditions foreseen by the manufacturer. This European Standard specifies the appropriate technical measures to eliminate or reduce risks arising from the significant hazards.These machines are designed for use with rotating diamond cutting-off wheels with a continuous rim and/or segmented rim.This European Standard does not apply to: -metal cutting-off machines;-wood and timber sawing machines;-machines with a feed or descent mechanism other than manual, or with a pedal;-mobile machines on a trolley travelling on the ground;-hand-held portable grinding and cutting-off machines;-hand-held portable grinding and cutting-off machines mounted on a support to be used in a fixed position.This European Standard does not cover the operation of transportable masonry and stone cutting-off machines in potential explosive atmospheres.This European Standard covers electrical hazards making reference to relevant European Standards (see 5.2).Those hazards that are relevant for all mechanical, electrical, hydraulic, pneumatic and other equipment of machinery and that are dealt with in standards for common use are not covered by this European Standard. Reference to pertinent standards of this kind is made where such standards are applicable and so far necessary.In this standard, the masonry and stone cutting-off machines for job site construction are called: "cutting-off machines" or "machines", and
