1 Scope
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.
