Floor cutting-off machines - Safety
This European Standard applies to self-propelled ride-on1) and 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:
- 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 European Standard covers electrical hazards by making reference to relevant European Standards (see 5.2).
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 European Standard. Reference to pertinent standards is made where such standards are applicable and so far necessary.
In this European Standard, floor sawing machines are called "machines", and cutting-off wheels are called "tools".
This European Standard applies primarily to machines which are manufactured after the date of approval

La transmission de d'énergie des scies à sol est mécanique ou hydraulique.
Cette norme européenne traite de tous les phénomènes dangereux significatifs spécifiques aux machines à scier les sols lorsqu'elles sont utilisées normalement et dans les conditions prévues par le constructeur (voir article 4). Cette norme spécifie les mesures techniques appropriées pour éliminer ou réduire les risques dus aux phénomènes dangereux significatifs.
Ces machines sont conçues pour être utilisées avec des disques à tronçonner par arrosage ou à sec. Ces disques à tronçonner et qui peuvent être notamment des meules à tronçonner soit des disques à tronçonner à base de diamant ou de nitrure de bore.
NOTE D'autres types d'outils peuvent également être utilisés suivant les caractéristiques de la machine et le travail pour lequel elle a été conçue, mais la présente norme ne couvre pas ces cas.
Ne sont pas couvertes par cette norme européenne :

The followingexception is possible.The presence of a device for stopping the tool(s) is not necessary when the absence or theopening of the guard creates a projection of water, which prevents the intended use of themachine. The guard shall remain fixed to the machine also in the open position and a warningsign (see figure D.3) shall be provided at the guard.5.1.2.3.2Open parts in the guardWhen the guard is designed with a section which can be opened at the front in order to visuallyposition the rotating tool in relation with the cutting line, or to allow it to perform a cut close to avertical surface, then:-the open section shall stay connected to the main guard;-the retaining device of the rotating tool(s) shall remain covered.SIST EN 13862:2002

Any brittleness damage of the guard materialshall be avoided. A permanent plastic deformation of the guard resulting from stresses isacceptable as long as the guard fulfils its protective function and can be normallyassembled/disassembled.The guards shall remain attached to the frame in the case of projection of segments of thecutting-off wheel.Annex C indicates characteristics of guards which correctly fulfil their function.5.1.4 Immobilization, stability5.1.4.1 ImmobilizationMachines whose nominal mass exceeds 100 kg shall be equipped with a device which allowstheir 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 brakedwheel(s).5.1.4.2 StabilityThe machines shall be designed and constructed so that they are sufficiently stable under theintended operating conditions, e.g. movement on site, cutting and parking.This shall be verified under the most unfavorable conditions specified by the manufacturer withthe machine located on a plane inclined at 10° to the horizontal and with the machine powersource switched off.

the spacer discswhich allows the width of the saw cut to be altered to make the required groove width shall havethe following performance requirements:-when rotating, the spacer disc(s) shall be prevented from moving in relation to thecutting tools and spindle by a positive device and not only by the tightening of theflanges;-the use of multiple mounted cutting tools shall be effected without additional modifica-tion to existing guards or exchange of guards;-secure and safe fixing of the multiple tools on the spindle shall be provided.The manufacturer shall indicate the limitations and intended modifications of this application
inthe operator’s instructions.5.1.7Starting with a crankInternal combustion engines which are hand-started using a crank shall be designed to avoidhazards caused by kick-back, for example, a safety crank shall be provided or the engine shallbe fitted with an internal anti-kick-back device.Easily accessible storage facilities shall be provided for safety starting cranks.SIST EN 13862:2002
