Removing & Installing Grinding Wheels
If you must conduct a ring test, the grinding wheel must be removed and reinstalled onto the hub. However, when doing this, remember that overtightening or rotating the spanner nut in the incorrect direction can damage threads, crack the grinding wheel, and make grinding wheel removal more difficult than necessary.
To remove and install a grinding wheel:
1.DISCONNECT MACHINE FROM POWER!
2.Place a sheet of plywood on top of the table to protect the table (Figure 12), and open the grinding wheel cover.

4.Position the spanner wrench on the spanner nut (Figure 14).
