Welcome to Quilting Board. Congratulations on getting a neat machine.
You should be able to get the machine to lift back out of the base with the silver lever on the front of the machine. You will probably have to undo the hand crank from the hand wheel. It looks like it you may have to adjust something that is in the hole in the front of the base, first. A horrible video, but it shows a machine like yours at
