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.
3. Position a 12mm wrench on the spindle shaft
that protrudes from the motor fan cover
(Figure 13).

in the direction shown in Figure 15.
