Since it was not close to an outlet, like a .....I did not try it in the shop . You guessed it, it didn't work. A wire for the foot control was not connected. Now I need to drive 45 miles to take it back. At least I have a 60 day warenty. Sure hope the person who had your machine took good care of it. Beautiful cabinet.
