Only hand-tighten the screw [1] with the Allen key!

4.4 Fitting angle wheel 87°/88°(optional)

The angle wheel can be fitted optionally instead of the angle adjuster. This helps the Discman to glide more smoothly over

the dressed surface. These angle wheels are only available for edge angles of 87° and 88°.

1) Shim ring

2) Position the angle wheel with label pointing to the Discman.

3) Screw

Fit and tighten the parts in this order.

4.5 Grinding disc feed
