Maybe that model was made by Singer??? Anyway, here is the link I found:

I did a search through the manual but did not find anything referencing dropping the feed dogs. As I mentioned before, I would look for a knob (at the base of the machine, usually around the stitch selection column) or a lever (in the bobbin area, with the bobbin cover open) with the teeth mark logo on it.
