First, ensure the needle is correctly inserted and is the right type and size for the fabric. Check for any bent or damaged needles and replace them. Verify that the needle is not hitting the presser foot or throat plate. Also, ensure the machine is threaded correctly and the tension is not too tight.

How often should I perform maintenance on the sewing machine?

Regular maintenance should be performed every 6 months, or more frequently if the machine is used extensively. This includes cleaning lint and dust, oiling moving parts, and checking for any loose screws or worn components.

What oil should be used for lubrication of the Dürkopp Adler 739-23?

Use high-quality sewing machine oil specifically designed for sewing machines. Avoid using household oils or other lubricants, as they may cause damage. Apply oil sparingly to the recommended parts as specified in the user manual.

How do I change the presser foot on the Dürkopp Adler 739-23?

To change the presser foot, raise the needle to its highest position and lift the presser foot lever. Press the presser foot release button to remove the current foot. Align the new presser foot with the presser foot holder and lower the presser foot lever to secure it in place.

What should I do if the machine is making unusual noises?

Unusual noises may indicate a need for cleaning or oiling. Turn off the machine and remove lint and debris from the bobbin area and feed dogs. Check for any loose parts or screws and tighten them. If the noise persists, consult a professional technician.

How can I set up the machine for sewing thick fabrics?

For sewing thick fabrics, use a larger needle and adjust the presser foot pressure to accommodate the fabric thickness. Increase the stitch length for better penetration and ensure the tension is set appropriately for thicker materials.
