I have the Moulinex Masterchef 750 (about 20 years old) and have misplaced my owner's manual. I would like to use one of the attachments for grating potatoes for latkes. I have used the discs but they shred the potatoes instead of grating. I'm not sure how to use what I think is the grating attachment. It might be a "ricer attachment" and I think I remember that food had to be cooked already to put through it. It is a bowl that replaces the food processor bowl and has 3 different size grating screens, a pusher blade, and a collar that goes on last.. It is the attachment on the far right in the attached photo. Any help would be appreciated!
