Store your grinding wheels in a dry environment. Don't subject them to near-freezing temperatures or to dramatic temperature changes. If a wheel is cracked, chipped or otherwise damaged, don't mount it. If it has been dropped, don't mount it.
Make sure that guards and work rests are all properly adjusted and secure before you start work. Safety guards should cover at least half of the wheel. Let a newly mounted wheel run for at least one full minute before grinding with it. Don't let anyone stand in front of or in line with the wheel during this time. Make sure flanges are clean, flat and free of burrs.
Don't overtighten the flange retaining nuts. Compare the safe maximum operating speed of your grinding wheel with that of your grinder. Don't use a grinding wheel whose top-rated speed is less than the grinder's speed. Never exceed a grinding wheel's maximum operating speed.
Never use a high-speed air sander with a grinding wheel. The speed of these pistol-grip air sanders far exceeds the maximum operating speed for grinding wheels. The result can be a potentially lethal wheel breakage. Many tragic injuries have resulted from using these high-speed sanders with grinding wheels. Don't let the next one happen on your watch. Instead, if you're using a high-speed air sander, only use sanding discs designed for the sander.
