It's entirely possible that you could use your treadmill here, there is a page on electronics that descibes how to buy the correct transformer and some resources for buying them, depends on the wattage/amperage or something.
http://www.uk-yankee.com/electronics.htmlJust reading that, I see that the motor that drives it, if it is a synchronus motor, will run a bit slower, 5/6, as the cycle lower here, that can cause it to overheat, I would check with the manufacturer, if they have a website, drop them an email and ask.
I hope that helps a bit, maybe you could sell it or store it and get another when you're here? They might have the same brand available here, you could ask them that in email as well.
