I have a Santinelli 7070 PLBM and I just got a 7070SX but it has a standard wheel set with no polishing wheel. The 7070 SX manual lists the PLB wheel combination that I have but POL does not come up as an option under Mode. Is it possible to put my PLB wheels in the 7070SX? If so, is there a setting that needs to be changed or does it require a software update, which I probably can't access, right?
