If your restoring the machine then you need to pull it out to get the presserfootbar lever out to polish it. Also you need to be sure the screw is snug holding the lever in anyway and the bar has to be out of the way to do it.
Plus it makes it easier to clean and detail the machine if it is out of the way.
