The 2 sides of the clamping nut are different. Screw
the clamping nut onto the spindle as follows:
See illustration B on page 2.
- A) For thin grinding wheels:
The edge of the clamping nut (7) faces upwards
so that the thin grinding wheel can be attached
securely.
B) For thick grinding wheels:
The edge of the clamping nut (7) faces
downwards so that the clamping nut can be
attached securely to the spindle.
- Lock the spindle. Turn the clamping nut (7)
clockwise using the 2-hole spanner (8) to secure.
