I just received my new CT33. I thought I would plug it in and get it a test yesterday and noticed a 220 volt type plug. I do not see anything in the owners manual saying it is 110 or 220 volt. Does this machine use 220 volt current? I just assumed when I ordered it, that it would use 110. I have 220 in my shop, just want to make sure. If it is 220, how does the hookup of sanders work? I have a 110 volt Makita sander I was going to use with this machine.
