Safety advice when using cutting discs and grinding wheels

For your safety you should ensure that you are fully aware of how to safely use cutting discs and grinding wheels

 

DOs

CUTTING DISCS AND GRINDING WHEELS 

ARE SAFE IF USED

CORRECTLY

  • Always handle and store wheels carefully. All cutting discs and grinding wheels should be placed on top of each other or stored in the original packaging.
  • Always visually inspect all wheels before mounting for possible damage in transit.
 
  • Always use a safety guard and ensure that it is correctly positioned and securely fitted.
    • lt should cover at least one half of the wheel and protect the operator in the unlikely event of a wheel breakage.
  • Always switch ‘OFF’ the power at supply source and/or remove the plug from the socket before changing the wheel.
  • Always use the tools supplied by the machine manufacturer to change the wheel.
  • Always ensure that the speed of the machine does not exceed the operating speed marked on the wheel.
  • Allow newly mounted wheels to run at operating speed, with the guard in place, for a reasonable time before cutting or grinding.
  • Always wear EYE PROTECTION.
  • Always wear appropriate safety clothing such as DUST MASK, GLOVES, EAR PROTECTION, OVERALLS AND SAFETY SHOES.
  • Always secure the workpiece firmly while it is being cut or ground.
  • Grind at an angle above 30 degrees to the workpiece with a depressed centre grinding wheel.
  • Keep the working area around cutting and grinding operations clear.
 

 

DON'Ts

CUTTING DISCS AND GRINDING WHEELS ARE DANGEROUS IF ABUSED

  • Store wheels in a damp atmosphere or in extreme temperatures.
  • Mount a damaged wheel.
  • EVER exceed the maximum operating speed marked on the wheel.
  • Force a wheel onto a machine spindle.
  • Tighten the mounting nut or locking flange excessively. Doing so can distort the flanges.
  • Use a machine which is not in good mechanical condition.
  • Use a machine without a wheel guard.
  • Use wheels without proper ventilation or dust protection equipment.
  • Stop the wheel by applying pressure to the periphery or face. Always switch the machine off and allow the wheel to stop revolving.
  • Allow the wheel to be trapped or pinched in the cut.
  • Apply excessive pressure onto the wheel so that the driving motor slows down.
  • Grind on the side of cutting discs wheels.
  • Grind with a depressed centre grinding wheel at an angle below 30° to the workpiece.
