To thread the Singer SISC550S, first raise the needle to its highest position. Place the spool of thread on the spool pin and secure it with a spool cap. Follow the threading path guide marked on the machine, ensuring the thread passes through the tension discs and needle eye.

What should I do if the machine is skipping stitches?

If the machine is skipping stitches, check that the needle is properly inserted and not bent. Ensure you are using the correct needle and thread for your fabric, and rethread the machine, checking for any obstructions or incorrect threading paths.
