Coated Abrasives

CoatedAbrasivesFibre DiscsPreparation for UseFibre discs must be used with the correct sized back-up pad. Do not use other fibre discsas a back-up pad. The diameter of the disc must be at least 3mm but not more than 15mmgreater than the diameter of the back-up pad. Do not use a fibre disc which is damagedin any way. Always check visually for damage before use. Make certain that both the disc and theback-up pad are fitted correctly to the machine spindle. The maximum peripheral operating speedof a fibre disc is 80m/s. This is shown on the box label by way of a red stripe, which is a FEPAStandard indicating a recommended operating speed of 80m/s. In no circumstances shouldthis speed be exceeded. The spindle speed of the machine must never exceed the maximumoperating speed of the disc: spindle speeds in rpm corresponding to 80m/s for different discdiameters are given below.MAXIMUM OPERATING SPEEDDisc Diameter80m/sMax rpm100mm 15300115mm 13300125mm 12300150mm 10200180mm 8600Grinding OperationThe fibre disc should only be brought into contact with the workpiece when the machine isrunning at its operational speed. The disc should be applied to the workpiece at the shallowestangle possible – about 10 degrees is recommended. Grind ‘off’ an edge rather than ‘into’ it whengrinding rough welds or metal edges. Do not attempt to use a fibre disc for slot grinding, cuttingoff or wet grinding. After use the angle grinder should be stored with care. The face of the discmust not be in contact with bench or floor.Personal ProtectionSafety goggles, ear defenders, safety gloves, dust masks and, if grinding conditions are severe,additional face protection. Leather aprons and safety shoes must be worn.PERSONAL PROTECTIONMouthProtectionWearGlovesEyeProtectionEarProtectionReadInstructionDryWetStorageFibre discs should be stored at a temperature of 18 – 22°C and 45% – 60% relative humidity.44
