Safety is top priority when using abrasives. Here is a short video on how to keep safe while grinding.
DOs for grinding wheel safety
-
DO check all wheels for cracks or other damage before mounting.
-
DO make sure the machine speed does not exceed the maximum operating speed marked on the wheel.
-
DO use an ANSI B7.1 wheel guard. Position it so it protects the operator.
-
DO be sure wheel hole or threads fit machine arbor properly and that the flanges are clean, flat, undamaged, and the proper type.
-
DO run wheel in a protected area for one minute before grinding.

-
DON’T allow untrained people to handle, store, mount, or use wheels.
-
DON’T use grinding wheels on pistol grip air sanders.
-
DON’T use wheels which have been dropped or damaged.
-
DON’T use a wheel on grinders rotating at speeds higher than the MAX RPM marked on the wheel or on grinders that do not show a MAX RPM speed.
-
DON’T use excessive pressure when mounting a wheel. Tighten enough only to hold wheel firmly.
-
DON’T alter a wheel hole or force it on a spindle.
-
DON’T mount more than one wheel on an arbor.
