This is an interesting thread because I'm running US gear in the UK.
The MFT seems to work fine.
I went to a Woodcraft to make sure I was going to pick up all the right parts and accesories. When I got there I found that they'd run out of TS55 saws, but I could have a TS75. So, the wife said I could spend the extra cash as we'd driven 2.5 hours to get to the shop, and I got the TS75 with the CT Mini.
I was annoyed to find that the TS75 can draw more current than the CT Mini is supposed to supply. For such a well built and thought out range of tools, i was annoyed that Festool don't give you any warnings about the issue of the current limitation. Not even a note in the catalog.

Okay, I should have checked, but I just a note would have helped.
Anyway. I fitted a UK 110v plug, got a transformer, and i'm running the extractor/saw on 110v/50hz. The transformer is rated at 3.3KVA for a 60% duty cycle, and about 1.6KVA continuous.
I dial down the speed controllers on both items, and although I understand that the saw could theoretically draw lots of current at lower revs, I'm not cutting oak beams like in the TS75 video on the Festoolusa website.
I've noticed a couple of things I've factored in to my considerations, I'd be interested in knowing what other people think of these deductions.
Firstly, if an appliance wants to use 1500 watts of power, a voltage drop might result in the appliance drawing more current. This worried me when thinking about running 120v tools at 110v. Would the tool draw even more current than on the label?
Secondly, I saw a Japanese tool that showed a lower current demand when the frequency of the supply voltage dropped. This made me think of an issue is audio test frequencies that have to be reduced in volume as the frequency goes up. This made me think that 50hz might be doing me a favor.
The tools are working well, I'll add to this thread if I run into trouble.
