For your safety you should ensure that you are fully aware of how to safely use cutting-off and grinding wheels. Here are the do's and don'ts for the safe use of these abrasives.
Cutting-off and grinding wheels are safe if used correctly.
- Always handle and store wheels carefully. All cutting 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.
Cutting-off 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-off wheels.
-
Grind with a depressed centre grinding wheel at an angle below 30° to the workpiece.
