To thread the Dürkopp Adler 1220-6, start by placing the spool on the spool pin. Then, guide the thread through the thread guide, down through the tension discs, and up through the take-up lever. Finally, thread the needle from front to back.
If the machine is skipping stitches, check the needle to ensure it is not bent or dull. Also, make sure the needle is inserted correctly and the thread tension is properly adjusted.
To adjust the tension, use the tension dial located on the front of the machine. Turn it clockwise to increase tension and counterclockwise to decrease tension. Test on a scrap piece of fabric to ensure proper tension.
Regular maintenance includes dusting the machine and oiling the moving parts. Use a soft brush to remove lint and follow the manufacturer's guidelines to apply sewing machine oil at designated points.
Ensure the feed dogs are engaged and not lowered. Also, check that the presser foot is down and applying adequate pressure on the fabric. Adjust the presser foot pressure if necessary.
To change the needle, first turn off the machine and remove the presser foot. Loosen the needle clamp screw and remove the old needle. Insert a new needle with the flat side facing the back and tighten the clamp screw.
Check if the machine is plugged in and the power switch is turned on. Verify that the foot pedal is properly connected. If the problem persists, consult a professional technician to inspect the motor.
Ensure the bobbin is wound evenly and inserted correctly. Clean the bobbin case and surrounding area of any lint or thread debris. Reinsert the bobbin case properly.
Unusual noises may indicate a need for cleaning or oiling. Turn off the machine and inspect for any loose screws or parts. If noises persist, consult the manual or a technician.
Adjust the needle type and size according to the fabric. Modify the thread tension and presser foot pressure to accommodate thicker or thinner materials. Conduct a test stitch on a scrap piece of fabric for best results.
