Can I use off-brand bobbins? We recommend to use only BERNINA quality bobbins because using off-brand bobbins can cause unsatisfying thread tension and other problems.
What's the use of the hole and the screw at the back of the presser foot? For attaching the seam guide.
Can the buttonhole be saved? Yes, but only in combination with using the buttonhole foot with slide #3A.
How often should the machine be oiled? The frequency of oiling depends on the number of the sewn stitches. We recommend to place a drop of oil onto the hook race before sewing for a longer period, but at least when the machine prompts you. When sewing bigger projects, you can oil the machine once a day.
The machine is running very slow. Check the slide speed control on the front of the machine and move to the right. Here you can set the maximum speed setting when sewing with the foot control or use it to adjust the speed when working with the start/stop button.
The machine sews on the spot There may be several reasons for this: The feed dog is down. The stitch length is set very small.
What are the holes on the top of the free arm for? For attaching BERNINA accessories such as the binder attachment, circular embroidery attachment, hosiery darning hoop, and much more.
What's the use of the eyelet on the top of the machine? For bobbin winding when the machine is threaded for sewing. The thread stands on the horizontal spool pin and is threaded first through the eyelet and then the pre-tension stud.
Whats the use of the vertical spool pin? Necessary when using a second thread for example sewing with the twin needle. For stacked (parallel wound) threads, use the vertical spool pin to allow the thread to evenly feed off the spool. Important: use the foam pad as base.
How should the upper thread be threaded for the double needle? Both threads follow the usual threading path, but one passes to the right and the other to the left of the tension disc
