5 Safety requirements and/or measures Machinery shall comply with the safety requirements and/or measures of this clause and in addition with !EN ISO 12100-1:2003 and EN ISO 12100-2:2003" for hazards relevant but not significant which are not dealt with in this standard. 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 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 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. SIST EN 13862:2002+A1:2009

!EN 60204-1:2006", in particular clauses 4, 5, 6, 14, 15 and 16. In addition to !4.4.3" of
!EN 60204-1:2006" these machines shall work as intended in an ambient temperature range of 0 °C to 40 °C. The enclosure of the electric controls shall provide a degree of protection of at least IP 54 as defined in EN 60529:1991. 5.2.2 Water pump Where water is supplied by an electrical pump for flushing the tool(s) the pump shall fulfil the relevant requirements of !EN 60335-1:2002 and EN 60335-2-41:2003". 5.3 Thermal hazards 5.3.1 Handles and other surfaces which require continuous contact shall have a surface temperature not exceeding 43 °C. 5.3.2 Controls and other parts of the machine which are contacted occasionally shall meet the limits as given in !4.2 of EN ISO 13732-1:2008" according to the chosen material for a contact period up to 5 s, lowest curve. 5.3.3 Hot areas which may be contacted unintentionally shall meet the levels of
!EN ISO 13732-1:2008" for a contact period below 1 s. These areas shall be either located at a distance greater than 120 mm from the gripping areas, or they shall be protected by shields. These shields shall be designed to reduce the heat transfer from the surface to the body of the operator. This could be achieved by a structured surface, ribs or special coating. 5.3.4 Test method The test method to verify the surface temperature of the machine is described in annex E. The machine parts whose temperatures exceed the permissible limits of !EN ISO 13732-1:2008" for contact not exceeding 1 s and whose surface is greater than 10 cm2, shall not be accessible to the test cone (see annex E). 5.4 Exhaust fumes (and gas) Internal combustion engine exhausts shall not be directed towards the operator when in the operating position as specified by the manufacturer. This requirement is considered fulfilled when the angle of the axis of the exhaust outlet and the longitudinal axis of the machine, measured from the position of the operator, is equal to or greater than 90°.
