Hi all!
Need help to correct the actions for disassembling the grinder and the calibration of the Burr
Tried to disassemble the grinder to clean the burrs, as shown in http://www.ecm.de/uploads/media/Bedienu ... tik_03.pdf
Removed the Bean hopper with lid, unscrewed the Safety screw and fixture was removed Grind level indicator. Tried to Unscrew the top block, and it is not removed. What is the reason?

I don't actually own this grinder, but a quick look at the manual makes me think perhaps you have not removed the allen screws? It also mentions that it may take some force to unscrew the upper burr bracket.

Maybe are you sure you are turning it the right way?

After many efforts it took off the top block. Cleaned burrs and assembled everything back. I'm happy . But there is another question. Why on the Burr there is no marking?
