Make sure abrasive wheels are safe to use.

(1) You must do the following before mounting a wheel:
(a) Visually inspect the wheel for cracks or damage.
(b) Perform a ring test for cracks if the size and shape of the wheel permits testing.
(c) Make sure the spindle speed of the machine is not greater than the operating speed of the wheel.
(2) You must make sure a damaged or cracked wheel is not mounted or used.
Wheels that have gouges, grooves, other damage, or material buildup on the grinding surface need to be dressed or trued to correct the problem. Wheels that cannot be trued are considered damaged and cannot be used.
