Floor cutting-off machines - Safety
This European Standard 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 European Standard 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 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 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.
NOTE Other types of cutting tools may also be used provided that they fall within the design and usage parameters of the machine. This standard does not cover this.
This European Standard 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;

For the application of EN 294:1992, !EN 953", EN 982:1996 and !EN 60204-1:2006" the manufacturer shall carry out an adequate risk assessment of their requirements, where it is necessary to make choices. NOTE This specific risk assessment should be part of the general risk assessment relating to the hazards not covered by this standard. Covering each significant individual hazard is sufficient for covering combinations of hazards. 5.1 Mechanical hazards 5.1.1 General As components and parts have to be manually handled, all the accessible parts, the tool excepted, shall not present sharp edges or angles/corners which could generate hazards when setting, using, handling, and maintaining the machine. Burrs resulting from, for example, manufacturing, casting or welding shall be eliminated and sharp edges shall be smoothed. SIST EN 13862:2002+A1:2009
EN 13862:2001+A1:2009 (E) 11 5.1.2 Protection against moving parts 5.1.2.1 Transmission parts Rotating transmission parts, for example drive shafts, couplings, belt drives shall be provided with fixed guards to prevent contact. !These guards shall comply with EN 953 and 5.3.2.2 of
EN ISO 12100-2:2003." Fixed guards shall be held in position either by welding or by mounting them in such a way that they can be opened or removed only with the aid of tools or keys. Guards shall comply with the provisions of EN 294:1992 on safety distances. !deleted text" 5.1.2.2 Connection between the cutting head and the frame When the vertical movement of the cutting head with respect to the frame is power driven, safety distances according to EN 294:1992 shall be provided. 5.1.2.3 Protection of the tool 5.1.2.3.1 General Machines shall be equipped with a guard covering at least the upper half of the tool(s) and its fixing device(s) (see figure C.1). Specifications concerning the strength of the guards are given in annex C. The guard(s) shall be so designed to facilitate safe and easy access for tool replacement. When the tool guard is removable to allow access to the tool fixing device, the machine shall be so designed that the rotation of the tool(s) may not be possible without the guard. The following exception is possible. The presence of a device for stopping the tool(s) is not necessary when the absence or the opening of the guard creates a projection of water, which prevents the intended use of the machine. The guard shall remain fixed to the machine also in the open position and a warning sign (see figure D.3) shall be provided at the guard. 5.1.2.3.2 Open parts in the guard When the guard is designed with a section which can be opened at the front in order to visually position the rotating tool in relation with the cutting line, or to allow it to perform a cut close to a vertical surface, then: the open section shall stay connected to the main guard; the retaining device of the rotating tool(s) shall remain covered. 5.1.2.3.3 Complementary requirements to prevent contact with the tool(s) out of the cutting area Contact with the tool(s) in rotation during the displacement of the machine outside the cutting area shall be prevented as follows: either all parts of the tool(s) (in particular the lower part) shall be guarded when the machine is set for displacement or; if the tool(s) is(are) not completely guarded, the machine shall be designed to allow displacement without the tool rotating, for example by means of a clutch and the guard shall carry a warning sign stating the following: SIST EN 13862:2002+A1:2009
EN 13862:2001+A1:2009 (E) 12 "All displacement of the machine outside the cutting area shall be carried out with the tool not in rotation“ (see figure D.2). 5.1.3 Minimum strength of the guard The guards for rotating tools shall be so designed to resist strains resulting from an accidental projection of a segment of the cutting-off wheel. Any brittleness damage of the guard material shall be avoided. A permanent plastic deformation of the guard resulting from stresses is acceptable as long as the guard fulfils its protective function and can be normally assembled/disassembled. The guards shall remain attached to the frame in the case of projection of segments of the cutting-off wheel. Annex C indicates characteristics of guards which correctly fulfil their function. 5.1.4 Immobilization, stability 5.1.4.1 Immobilization Machines whose nominal mass exceeds 100 kg shall be equipped with a device which allows their immobilization (e. g. mechanical parking brake or self-sustaining system) on a slope of 10° with the machine in a position and configuration giving the maximum load on the braked wheel(s). 5.1.4.2 Stability The machines shall be designed and constructed so that they are sufficiently stable under the intended operating conditions, e.g. movement on site, cutting and parking. This shall be verified under the most unfavorable conditions specified by the manufacturer with the machine located on a plane inclined at 10° to the horizontal and with the machine power source switched off. The immobilization means (if any) shall be in use during the test. For machines without immobilization means the wheels shall be blocked for the test. Under these test conditions the machine shall not overturn. 5.1.5 Transport and handling The movable parts of the machine shall be either lockable or removable to avoid any risk of shearing or crushing e.g. during handling and carrying. NOTE For technical requirements relating to transport and lifting of the machine see !5.5.5 of
EN 12100-2:2003". 5.1.6 Fixing of the tool(s) 5.1.6.1 Device for mounting the rotating tool(s) The device for mounting the rotating tool(s) shall be so designed that loosening and untightening shall be possible only by an intentional manual action (e.g. retaining the rotating tool(s) on the drive spindle by a threaded nut, the thread direction of which prevents unscrewing of the nut during the cutting operation). 5.1.6.2 Flanges 5.1.6.2.1 Mounting of a cutting-off wheel The flanges intended to mount a rotating tool shall comply with the requirements of annex B.
