Hi, my name is Matthew Christian from Tampa, Florida and on behalf of Expert Village today I'd like to talk to you about a portable electric sander. As I mentioned earlier most portable electric sanders run on 110 or house current. Pretty much any extension cord will work. These sanders don't require significant amounts of power. You don't need a very heavy gauge extension cord, your standard, I think this is a fourteen gauge extension cord, will do. But to power it up, first, make sure your sander is in the off position, make sure the power switch is off. And then a little helpful thing that I like to do is before I connect my extension cord, to help keep it from coming unplugged while you're using it, we're going to tie a knot in the cord. We'll just hold the two, come around, draw it into a knot and now you can plug it in. Notice that one pole on the extension cord is larger than the other so it will only go in one way. Plug it in and you're ready to go.
