Mounting/Removing

Wheel

Before mounting a grinding wheel (new or used), perform the following procedures:

•Wheel Inspection (Page 26)

•Ring Test (Page 26)

•Wheel Balancing (Page 27)

Do not use a wheel that is suspected of having cracks, or if you can see chips, nicks, or dents in the wheel surface. These conditions can lead to wheel failure where the wheel flies apart at oper- ating speed. Always be sure to use a wheel that is rated for operating at speeds of at least 3450 RPM.
