Some of us will have power issues, 220VAC outlets (particularly NEMA L6-30) are hard to find here in the USA. In this case, it's suggested to "swap the plug". Okay, great, how do you do that? This review lost a star because there is no discussion of this subject in the (skimpy) owner's manual.This machine's main power cord has three wires inside: one is blue, one is brown, and one is yellow/green. I went and researched the subject, this unit is wired by EUROPEAN standards, which say: blue = common, brown=hot, yellow/green=ground. I'm gonna go try that in a 110VAC outlet, will let you all know what happens (if I don't hurt myself, that is!).
