WHAT did we do before technicians?
I don't have a Bernina, mostly Janomes....real workhorses...I care for my own machine, clean/oil, check inside the machine, use only machine oil or grease recommended for specific areas. NEVER have taken any of my machines in for a check up. I will if I have a serious problem.....haven't so far. Dealers here charge $150 plus to "service" a machine, which is what I do.....
