Singer 4220, 4228 Instruction Book

To thread the Singer 4220, start by raising the presser foot and turning the handwheel to raise the needle. Place a spool of thread on the spool pin and secure it with the spool cap. Follow the threading path indicated on the machine, ensuring the thread passes through the thread guide, tension discs, and the take-up lever before threading the needle.
First, ensure you are using the correct needle size and type for your fabric. Check that the needle is inserted correctly and not bent or damaged. Re-thread the machine, ensuring the thread is properly seated in the tension discs, and check that the bobbin is inserted correctly. Ensure the presser foot is down while sewing.
To adjust the tension, locate the tension control dial on the front of the machine. Turn the dial to a higher number to increase tension or to a lower number to decrease tension. Test on a scrap piece of fabric to ensure the stitches are balanced.
Skipping stitches can be caused by a dull or incorrectly inserted needle. Replace the needle and ensure it's inserted with the flat side facing the back. Also, check the threading of the machine and ensure the presser foot is down while sewing.
Regular maintenance includes cleaning the bobbin case area to remove lint and dust. Use a small brush or vacuum attachment. Oil the machine as directed in the manual, typically in the hook race area. Always unplug the machine before cleaning.
The Singer 4228 uses Class 15 transparent bobbins. Ensure you are using the correct bobbin size to prevent jamming and tension issues.
First, check that the machine is threaded correctly with the presser foot up. Ensure the bobbin is wound evenly and inserted correctly. Adjust the upper thread tension using the tension dial and test on a scrap fabric. If issues persist, consult the manual or a professional technician.
Yes, the Singer 4228 can accommodate a twin needle. Ensure the machine is properly threaded for twin needle use and use a second spool pin for the additional thread. Adjust the stitch width to avoid needle breakage.
A loud noise could indicate that the machine needs cleaning or oiling. Check for lint build-up in the bobbin area and remove it. Ensure the needle is correctly inserted and not bent. If the noise persists, have the machine serviced by a professional.
To set up for free-motion quilting, drop the feed dogs using the lever or switch on the machine. Attach a darning or free-motion quilting foot. Set the stitch length to zero and manually move the fabric to create your design.
