I brought this laminator from the U.S down to Peru with me. It was new when I brought it down here, but I had tried it out back in the States to make sure it worked. Today I turned it on (for the first time since arriving in Peru). It worked just fine at first, but after about 10 minutes it just shut off. I thought maybe it had an automatic shut-off button, but then when I tried to turn it back on about half an hour later, it wouldn't turn back on. Is there any advice you can give me for what to do?
