To thread the Dürkopp Adler 268, first ensure the machine is turned off. Raise the presser foot and guide the thread from the spool through the thread guide, down through the tension discs, up to the take-up lever, and finally through the needle eye from front to back.
To adjust the tension, locate the tension discs on the front of the machine. Turn the tension knob clockwise to increase tension and counterclockwise to decrease it. Test on a scrap piece of fabric to ensure the stitch quality is balanced.
Skipped stitches can be caused by a dull needle, improper threading, or incorrect tension settings. Replace the needle, re-thread the machine, and check the tension settings to troubleshoot the issue.
Regular maintenance includes cleaning lint from the bobbin area, oiling the machine according to the user manual, and checking for worn parts. It's important to service the machine annually by a professional technician.
To change the needle, turn off the machine and raise the needle to its highest position. Loosen the needle clamp screw, remove the old needle, insert a new needle with the flat side facing the back, and tighten the screw securely.
Check the power supply and ensure the machine is plugged in. Inspect the fuse and circuit breaker. If the machine still doesn't start, consult the user manual or contact a professional technician for further diagnosis.
Ensure the feed dogs are engaged and the presser foot pressure is adequate for the fabric being sewn. Adjust the stitch length dial to the desired setting and test on scrap fabric to verify consistency.
Common causes include incorrect threading, tension too tight, a damaged needle, or inferior thread quality. Re-thread the machine, adjust the tension, replace the needle, and use high-quality thread to resolve the issue.
Locate the presser foot pressure adjustment screw on the top of the machine. Turn it clockwise to increase pressure or counterclockwise to decrease it. Adjust according to the thickness of the fabric being sewn.
Ensure the feed dogs are raised and not obstructed. Check the presser foot pressure and adjust if necessary. Make sure the fabric is positioned correctly and that the stitch length is set appropriately for the fabric type.
