I am desperately seeking an owner's manual for a Craftsman variable speed 10-in. band saw. It lists it as 120 volt, 60 hz 2.4 amps. We bought it used and the model number plate is missing along with part of the label on the front side of this thing. I've located the following numbers on the outside and underside of it: 5J65, E129484, 821902 and 320265. Inside the saw, I found these numbers: 821439E and 821438. Please help!
