- Do always follow instructions for correct storage.
- Do always visually inspect grinding wheels before mounting for possible damage during transport and eliminate damaged ones.
- Do always use a safety guard, which should cover nearly one half of the grinding wheel.
- Do always use non-reinforced cutting-off wheels on fixed stationary machines.
- Do always switch off the power at the supply and/or unplug the machine before changing the wheel.
- Do always use the tools supplied by the machine manufacturer to change the wheel.
- Do always ensure that the spindle speed of the machine is no higher than the operating speed marked on the wheel.
- Do always use the correct wheel mounting flanges for grinding wheels and check that they are undamaged, clean and free of burrs.
- Do always use blotters between the mounting flanges and the wheel sides for soft mounting of flat cutting-off wheels.
- Do always allow newly mounted wheels to run.
DONTs
- DON’T store wheels in a damp atmosphere or in extreme temperatures.
- DON’T use non-reinforced cutting-off wheels on portable machines.
- DON’T handle wheels roughly.
- DON’T drop portable machines or lower to the floor by the cable or air hose. A wheel can be easily cracked by the weight of the machine if it is up.
- DON’T mount a damaged wheel.
- DON’T EVER exceed the maximum operating speed marked on the wheel.
- DON’T force a wheel onto a machine spindle.
- DON’T use mounting flanges which are incorrect, damaged, dirty or worn out.
- DON’T tighten the mounting nut or locking flange excessively. This can distort the flanges.
- DON’T use blotters for soft mounting of depressed-centre concave wheels
