Please be advised that this cutter is specifically made for the newer model of the Imperia Pasta Machine, represented by a blue power switch.
If your pasta machine is the older version, represented by a white power switch, then these cutters WILL NOT work with your machine. You can attach them to the back, but the only way to operate them would be manually using the hand crank.
Old P108 cutters have a small round opening on the side. New P108 Cutters now directly attach to the machine on the SIDE. A straight pin adaptor is necessary to attach the cutter.
