Trang 6Introduction
This European Standard is a Type C-standard as stated in !EN ISO 12100-1:2003"
The machinery concerned and the extent to which hazards are covered are indicated in the scope of this
European Standard
1 Scope
This European Standard applies to !deleted text" 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;
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”

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:
Trang 14"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

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
