How to replace the profiling ring?
Remove all eight screws of the upper and lower unit. Then you can take off the front part and replace the profiling rings.
Be careful there are o-rings behind the front part.
In case you do not have the spare profiling rings, we recommend you to order the profiling disc complete, with carbide ring:
order no. 009904 (without cooling) order no. 011123 (with cooling)
depending on your configuration.
