I have had my MIL old singer in our bonus room for a long time and finally opened it and set it up--it is a cabinet where the machine folds down. It seems to work fine but it needs a good cleaning and I think probably some maintenance. Is it ok to just follow the manual and do what it says or do you all think I need to take it a professional? It would be nice to have this as a 2nd machine for piecing when I have my other machine set up for quilting. Thanks in advance for any help, once I get it cleaned up I will post pics.
