This document applies to pedestrian controlled floor sawing machines having power feed, manual feed or hand feed (see 3.2) 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 pertinent to floor sawing machines, when they are used as intended and under the conditions foreseen by the manufacturer (see Clause 4). This document specifies the appropriate technical measures to eliminate or reduce risks arising from the significant hazards.

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, according to EN 13236.

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.

This document covers electrical hazards by making reference to relevant European Standards (see 4.2).

Those hazards that are relevant for all mechanical, electrical, hydraulic and other equipment or machinery and that are dealt with in standards for common use are not covered by this document. Reference to pertinent standards is made where such standards are applicable and so far necessary.

In this document, floor sawing machines are called "machines", and cutting-off wheels are called “tools”.

This document applies primarily to machines which are manufactured after the date of approval of the standard by CEN.

This document 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 document 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 document 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 according to prEN 13236:2017.

This document 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 document does not cover the operation of transportable masonry and stone cutting-off machines in potential explosive atmospheres.

This document covers electrical hazards making reference to relevant European Standards (see 4.3).

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 document. Reference to pertinent standards of this kind is made where such standards are applicable and so far necessary.

In this document, the masonry and stone cutting-off machines for job site construction are called: "cutting-off machines" or "machines", and cutting-off wheels are also called: "tools".

This document applies primarily to machines which are manufactured after the date of approval of the standard by CEN.
