Safety and application instructions for working with diamond tools: - - - - The arrow on the diamond cutting disc indicates the running direction of the disc. The drill hole of the diamond cutting disc or the socket of diamond tools must correspond to the respective machine socket, the disc is to be inserted free of axial or radial run-out. Work without contact pressure, the dead weight of the machine suffices. The maximum cutting depth is set according to the diameter of the diamond cutting disc: Diameter of the disc (mm) max. cutting depth (mm) 110, 115, 125, 150 20 180 30 230 40 300 50 350 60 - - - - - - - The maximum circumferential speed is 80 m/s in dry cut. This can be lower for abrasive materials (marble, hard sandstone: 45-50 m/s) or harder materials (e.g. granite 30-35 m/s), for wet cut please note the instructions of the machine manfacturer! Cooling breaks - for dry cut discs a cooling break of 10 seconds is to be made every 2 minutes during which the disc is to be removed from the cut so that it can cool during the run. For wet cut discs ensure a supply of sufficient coolant as well as the removal of lubricating liquid from the groove. Large material cross-sections are to be cut over several working processes. When the cutting performance diminishes the disc can be sharpened using an abrasive material (e.g. sandstone). Diamond discs are constructed for straight cuts only! The cutting of curves can result in cracks in the steel core or damage to segments - danger of injury! Damaged diamond tools, unbalanced cutting discs or tools that have been dropped may no longer be used - danger of injury! Always work with eye protection and protective clothing! For your working protection please observe the following safety pictograms established by the Federation of European Producers of Abrasives (FEPA): Use a dust mask! Use ear protection! Use eye protection! Use gloves! Observe the safety instructions!
