Frequently Asked Questions - 961-16 Dürkopp Adler
How do I thread the Dürkopp Adler 961-16?
First, raise the presser foot and turn the handwheel to bring the needle to its highest position. Place the thread spool on the pin, guide the thread through the tension discs, then through the take-up lever, and finally through the needle eye from front to back. Ensure the thread is properly engaged in the tension mechanism.
How to adjust stitch length on this machine?
The stitch length is adjusted using the stitch length dial located on the front of the machine. Turn the dial to the desired setting; higher numbers produce longer stitches. For reverse stitching, press the reverse lever while sewing.
How do I change the needle on the 961-16?
Loosen the needle clamp screw with a screwdriver. Remove the old needle and insert a new one with the flat side facing the back of the machine. Push the needle up as far as it will go, then tighten the clamp screw securely.
What oil should I use for lubrication?
Use only sewing machine oil specifically designed for industrial machines, such as Dürkopp Adler recommended oil. Apply a few drops to the oil wicks and hook area daily. Do not over-oil.
Why does the thread keep breaking?
Thread breakage can be caused by incorrect tension settings, a burred needle, or improper threading. Check the tension discs for lint, replace the needle if bent, and re-thread following the correct path. Also ensure the thread is suitable for the fabric.
How to adjust thread tension?
Turn the tension dial located on the front. Increase tension by turning clockwise for tighter stitches, or counter-clockwise for looser. The bobbin tension can be adjusted by turning the screw on the bobbin case. Test on a scrap fabric.
How to clean the feed dogs?
Remove the needle plate using a screwdriver. Brush away lint and dust from the feed dogs and surrounding area with a small brush. Reinstall the needle plate and tighten screws.
How to replace the bobbin?
Open the bobbin cover and remove the empty bobbin. Insert a wound bobbin with the thread unwinding in the correct direction (check manual). Pull the thread through the bobbin tension spring and close the cover.
What to do if the machine skips stitches?
Check that the needle is not bent or blunt and is inserted correctly. Ensure the needle size matches the thread and fabric. Also inspect the hook timing; if misaligned, contact a technician.
How to perform basic maintenance on the 961-16?
Daily: clean lint from feed dogs and hook area, oil indicated points. Weekly: check belt tension and clean the motor filter. Monthly: lubricate moving parts and check for loose screws. Always refer to the manual for detailed intervals.
