I was curious about your machine. I found a picture at https://www.ebay.ie/itm/Pfaff-Hobbym...-/333230186211 I then went to http://www.pfaff.com/Support-and-Updates/Support and could not find a Hobbymatic 939 I looked at some of the other manuals and found that the Hobbymatic 933 & 953 have the wheel in the pillar. One has the lift up top handle and the other has the lid for the accessories, but both use the same manual. The 933/953 both have 12 keys on the bottom of the pillar. I found the Hobbymatic 904-1. 919-1 and 946-1 use the same manual. The 919-1 has the lift up handle, the right number? of buttons, but no wheel on the pillar. The 946-1 has the lift up lid and has a wheel on the pillar.

I also found some other Hobbymatic manuals at https://www.manualslib.com/manual/50...matic-935.html and https://www.manualslib.com/manual/10...matic-917.html

I know Pfaff, as indicated above & others that I have, will put several models in one manual. I did not check any of the Hobbymatic 800s to see if there were any similarities or not. You might have to combine manuals to figure out the 939. If I had a Hobbymatic 939, I would probably just see if one or two of the other manuals was close enough to figure it out. If I couldn't figure out the 939, I think I would check to see if Pfaff Customer Service could help ( http://www.pfaff.com/Support-and-Updates/Support ).
