Singer Professional Sewing Machine Model #CG-550C withPower Cord & Pedal -UNTESTED

Singer Professional Sewing Machine Model #CG-550C w/Power Cord & Pedal -UNTESTED. Comes with only what is shown in the photos. I have no idea how to test. The unit powers on and I can get the needle assembly to move up and down. I tried pushing the pedal down and it also moved the needle up and down.

There is a little lever on the back side of the unit that looks bent. No idea what it does or if it is damaged.
