    • On the rear side is an obstacle: four "oval head screws" looking like rivets. You can remove them using a special oval drive bit. They are sold at iFixit with the tool kits as well as some Jura suppliers or somewhere in the internet. Jura wants to keep us out of our own machines!

    • Using an oval head bit you can screw them out. If you haven´t got one you can carefully use pliers. It is a good idea to later change the screws for normal ones.
