There is a slow speed potentiometer screw on the bottom of some Bernina electronic foot controls to set the machine at it's slowest starting speed. You machine will run a lot smoother if the motor armature has been cleaned and polished of any black carbon buildup from the motor brushes wearing down. It also helps if the machine has been cleaned and oiled so that the handwheel is extremely easy to turn (no binds). John
I was extremely pleased with the speed of service and my product. I called your company to ask a question about the product before I placed my order online. I can't remember her name, but the woman that I spoke with was very helpful. I was looking for a replacement for the foot control for my Bernina 830 that I purchased in 1976. I had the guts of the control replaced about 20 years ago, but it stopped working again. Since I just recently moved to Louisiana, I didn't know where a good service dealer was close to me. I was thrilled to find the new foot control at your company. It worked perfectly after I adjusted the speed with the screw on the bottom of the control. Thank you
