The ideal needle size for the Dürkopp Adler 550-16-26 is typically 110/18. However, the size may vary depending on the fabric thickness and type.
To thread the machine, start by placing the spool on the spool pin, guide the thread through the thread guides, tension discs, and finally through the needle eye from front to back. Refer to the user manual for detailed threading diagrams.
If the motor overheats, turn off the machine immediately and let it cool down. Check for any obstructions in the motor area and ensure proper ventilation. If the problem persists, consult a professional technician.
To adjust the stitch length, locate the stitch length dial on the machine and turn it to the desired setting. The numbers on the dial correspond to the stitch length in millimeters.
Regular maintenance includes cleaning the bobbin case and feed dogs, oiling the machine as per the manual instructions, checking the needle for wear, and ensuring the tension settings are correct.
If the machine is skipping stitches, check the needle for damage or incorrect installation, ensure the thread is correctly threaded, and adjust the tension settings. Also, verify that the fabric is suitable for the needle size used.
To replace the bobbin, first, remove the bobbin case cover, then take out the empty bobbin. Insert a new bobbin into the case, ensuring it unwinds in the correct direction, and replace the cover securely.
To resolve tension issues, re-thread the machine, check for any tangles or obstructions, and adjust the upper and lower thread tensions gradually until the stitching appears balanced and even.
Use high-quality sewing machine oil specifically designed for industrial machines. Avoid using household oils or other lubricants, as they can damage the machine components.
Calibrating the timing involves aligning the needle and hook precisely. It is recommended to follow the service manual instructions or consult a professional technician to avoid misalignment and potential damage.
