Husqvarna serger model 910
Does anyone have one of these? I just bought one, the guy says it was his mother's and has been in their closet for 8 years, since his mother passed away. It looks like a brand new machine, I don't believe it has ever been unpacked since it was bought. The problem is the hand wheel will not turn, it's stuck very firmly, so the machine just makes a humming sound when you step on the pedal. Can anyone help or give some advice? Thanks, Sharon
