4 Working with the Discman
4.1 Connecting to the power supply
For an optimum workplace layout, route the power cable
down from the ceiling.
4.2 Before commissioning
Before you start working, remove the locking bolt and the Allen key from the device!
4.3 Grinding angle setting
To set the grinding angle, release screw [1].
Turn the angle adjuster [2] manually to the desired position.
Turning by one number is equivalent to changing the angle by one
degree. The angle adjuster latches every 0.5 degrees.
Hand-tighten the screw [1] with an Allen key.

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
Turning the knurled nut in PLUS direction [1] moves the
grinding disc towards the steel edge to be ground.
