This document applies to pedestrian-controlled floor-sawing machines having travel power feed or manual feed (see 3.1) for sawing, grooving and milling floor surfaces made of concrete, asphalt and similar mineral building materials where the main power is supplied by electric or internal combustion prime engine. The power transmission of floor-sawing machines is mechanical or hydraulic. This document deals with all significant hazards, hazardous situations or hazardous events relevant to floor sawing machines, when they are used as intended and under conditions of misuse which are reasonably foreseeable by the manufacturer (see Annex A). This document specifies the appropriate technical measures to eliminate or reduce risks arising from the significant hazards during the lifetime of the machinery as described in EN ISO 12100:2010, 5.4. These machines are designed for use with rotating cutting-off wheels for wet and dry cutting. These cutting-off wheels can be either a diamond cutting-off wheel or a boron nitride cutting-off wheel. This document does not apply to: - self-propelled ride-on floor-sawing machines; - machines moving along a rail; - hand-held portable cutting off machines for construction materials mounted on a mobile support, to be used as floor saws; - remote-controlled machines. In this document, floor-sawing machines are called “machines”, and cutting-off wheels are also called “tools”. This document applies to machines which are manufactured after the date of approval of the standard by CEN.
