Oh, THANK YOU for all this information! You don't know how I appreciate it.
I'm excited to have the machine but reticent to use it yet since it's still so unfamiliar. You know, what the belt goes around, how to wind and insert the bobbin in the shuttle, how to use the shuttle...all those things.
The manual links you provided are the same ones I'd found so I now know they're the right ones. I've watched several youtube videos and, you're right, they say to use sewing machine oil to clean it. I tried it and it worked a charm - the decals are much brighter looking now. It didn't look all that dirty until I cleaned it. I was truly surprised at how much dirt I was able to get off using oil.
Thank you again!
