Do you have a question about the Singer and is the answer not in the manual?
I have a Singer Heavy Duty. When starting the machine (pedal), the machine stitches in place and does not move forward automatically. Only when I pull the fabric, but the stitch is not good. How can I solve this?

I move the button to change the needle position. And it doesn't respond to any changes. It is only on the left side. What should I do? I bought it in January 2023. Please, I await your response.

Post reaction Sharon September 15, 2023I can’t get the bobbin to lock into the casing in the machine so I’m unable to thread the machine - what am I doing wrong
Same question Type your response here Add my commentTo lock the bobbin into the casing and thread the Singer Heavy Duty sewing machine, follow these steps: 1. Place the thread and corresponding spool holder onto the spool pin. 2. Snap the thread into the thread guide. 3. Wind the thread clockwise around the bobbin winder tension discs. 4. Thread the bobbin as illustrated and place it on the spindle. 5. Push the bobbin spindle to the right. 6. Hold the thread end securely. 7. Step on the foot control pedal. 8. Trim the thread close to the bobbin and continue winding until the bobbin is full. 9. Cut the thread, push the bobbin spindle to the left, and remove the bobbin. To start sewing, push the bobbin winder spindle to the left (sewing position). Please note that when the bobbin winder spindle is in the "bobbin winding" position, the machine will not sew. Make sure to turn the handwheel counterclockwise to lower and raise the needle. If it is difficult to raise the bobbin thread, check to ensure that the thread is not trapped by the hinged cover or the removable extension table. Gently pull on the upper thread to bring the bobbin thread up through the needle plate hole. Finally, lay both threads to the back under the presser foot.
