It is strongly NOT recommended to use abrasive tools lacking the oSa label or the EN13236 compliancy

 


DO's

DIAMOND BLADES

ARE SAFE IF USED

CORRECTLY

  • Read the safety instructions provided by the abrasives and equipment supplier
  • Store diamond blades in dry, frost-free conditions, avoid large temperature variations
  • Ensure that the product is suitable for its purpose
  • Handle, store and transport products with care
  • Disconnect the power to the machine before fitting the diamond blade
  • Examine all products before mounting and periodically during blade use for possible defects or damage (core flatness, fatigue cracks, undercutting, arbor damage…)
  • Check that correct mounting devices are used and that they are clean, undistorted and free from burrs
  • Ensure that work rests are properly adjusted and secure
  • Always use a correctly designed and adjusted guard (on the blade and belts)
  • Ensure that the workpiece is secure
  • Wear appropriate personal protective equipment at all times
  • Avoid clogging and uneven wear to ensure that the product is working efficiently
  • Ensure accordance between product direction arrow / machine rotation
  • Ensure that all machines using abrasives meet the requirements of the current european machinery directives-CE
  • Be aware of the hazards likely during the use of abrasives and observe the recommended precautions to be taken:
    • Bodily contact with the abrasive product at operating speed
    • Injury resulting from product breakage during use
    • Grinding debris, sparks, fumes and dust generated by the grinding process
    • Noise
    • Vibration

 


DONT's

DIAMOND BLADES ARE DANGEROUS IF ABUSED

  • Allow untrained people to use abrasives
  • Use a product that is damaged or one which has been dropped
  • Use a product if it cannot be properly identified
  • Use a machine that is not in good working order or one with defective parts
  • Force the abrasive onto the mounting device or modify the size of the mounting hole
  • Exceed the maximum operating speed marked on the product
  • Apply shock or excessive force to the product or let it overheat
  • Use mounting flanges which are not clean and flat
  • Tighten the mounting device excessively
  • Start the machine until the guard is in place and fastened securely
  • Continue to use a product if vibration occurs, true or replace it
  • Grind on the part of the product which is not designed for the operation
  • Start the machine with the workpiece in contact with the abrasive product
  • Grind material for which the product is not designed
  • Stop the abrasive by applying pressure to its surface, let it stop naturally
  • Exceed permissible rotation speeds: refer to values engraved on product
  • Use blades with missing segments or core cracks
  • Use dry products marked for wet use
  • Wear loose clothing, ties and jewellery
  • Use abrasive products near flammable materials

 

 


ALWAYS

  • Wear eye protection EN166B
  • Wear gloves EN 388 cat.2
  • Wear hearing protection EN352
  • Wear a respirator EN149
  • Read the instructions
  • Not to be used for side grinding

NEVER EXCEED - the maximum operating speeds:

  • Handheld blades diam < or = to 230mm : 80 m/s
  • Handheld blades diam > to 230 mm: 100 m/s
  • Others: 63 m/s
