To thread the Singer 3323, raise the presser foot lifter, place the spool of thread on the spool pin, and follow the threading path indicated on the machine, passing the thread through the thread guide, tension discs, and take-up lever, then thread the needle from front to back.
Ensure that the needle is correctly inserted and not bent or damaged. Use the appropriate needle type and size for the fabric and thread. Check that the presser foot and needle plate are correctly attached and that the machine is threaded properly.
Adjust the tension by turning the tension dial located on the front of the machine. For general sewing, the tension is typically set between 3 and 5. Test on a scrap fabric to ensure the stitches are balanced.
Regularly clean the machine by removing lint and dust with a small brush, oil the moving parts as instructed in the manual, and replace the needle after every project or after 8 hours of sewing.
Check for tangled threads or debris in the bobbin case, ensure the needle is not bent, and verify that the machine is properly threaded. Also, oil the machine to ensure smooth operation.
Use the buttonhole foot and select the buttonhole stitch on the stitch dial. Place the fabric under the foot, lower the buttonhole lever, and sew by following the machine's instructions for automatic buttonhole creation.
Ensure the presser foot is down, check that the feed dogs are up, and clean any lint or debris from the feed dogs area. Adjust the presser foot pressure if necessary.
Turn off the machine, lower the presser foot, and unscrew the needle clamp screw. Remove the old needle, insert a new one with the flat side facing the back, and tighten the needle clamp screw.
Ensure the needle is correctly installed and not damaged. Check that the thread is correctly threaded and the tension is set properly. Use the correct needle and thread for the fabric type.
Re-thread the machine, check if the presser foot is down, and ensure the bobbin is wound and inserted correctly. Adjust the tension dial and test on scrap fabric until stitches are balanced.
