I WOULDN'T PLUG IT IN IF I WERE YOU!!!!!
I think you're very wise NOT to plug that machine in.
You never know what could possible happen. Fire. Explosion. Flood.
I heard of an elderly couple who plugged in an old machine, just like the one you have. They were friends of my aunt.
The old lady lifted the lid, looked in, and got hit in the head with the lint filter. She got knocked out, but the husband died trying to give her CPR.
What you should do--right now--without further delay--is sell that dangerous piece of metal before something terrible happens.
In fact, I'll help you. I'll take that danger right off your hands. I've got a truck, and I can make it to Vermont.
How much do you want for it?

P.S. If a guy named Graham contacts you, he doesn't need any more machines.
