How to Troubleshoot a Singer 221

The sewing machine was originally patented in 1791.

Proper upkeep and maintenance are vital to the continued life of any sewing machine, especially vintage types such as the Singer 221 Featherweight. Using a broken or incorrect needle, improper tension and incorrect threading are all issues that can affect the performance of the machine. Troubleshooting these areas should be the primary focus if the Singer 221 is experiencing problems.

Things You'll Need

• Singer 221 Sewing Machine Manual
• Singer Sewing Machine Oil
• Sewing machine needles
• Flathead screwdriver
• Thread

Instructions

If the Singer 221 is Noisy

1. Add oil to the machine to ensure it is properly lubricated. Check the owners manual to determine the correct amount of oil to add and the specific points that need to be oiled.

2. Check the needle to ensure it is intact. If the needle is broken, bent or dull, it will need to be replaced with a needle of appropriate size.

3. Check the bobbin, the bobbin plate, the bobbin case and the hook for excess lint buildup. Remove any excess lint you find.

If the Singer 221 Skips Stitches

1. Check the needle and ensure it is the appropriate size and type for the fabric being sewn. Woven fabrics require a sharp needle, whereas knit fabrics require a ball point needle. Home decor and denim fabrics also require different types of needles, respectively.

2. Ensure that the needle is properly set in the needle bar. This is another common issue that causes skipped stitches.

3. Check the needle for damage. A damaged needle may also cause stitches to be skipped. Replace if necessary.

If the Tension is Incorrect

1. Consult the owners manual for the correct steps in threading the Singer 221 sewing machine. Failure to follow these instructions may result in incorrect tension in the thread. Adjust the tension as needed.

2. Check the bobbin tension. If it needs to be adjusted, hold the bobbin case at a vertical angle and move the top screw to the right to tighten the tension, or move it to the left to make the tension more loose.

3. Check the tension on the upper tension assembly. If the above steps do not solve the tension issues, the entire upper tension assembly may need to be removed, taken apart, and reassembled. Consult the owners manual for the steps to perform this procedure.

If the Thread Breaks

1. Consult the owners manual for the correct steps in threading the Singer 221 sewing machine. Failure to follow these instructions may cause the thread to break.

2. Check the bobbin and thread tension and loosen if necessary. Too much tension can cause breakage.

3. Ensure that the proper needle is being used for the fabric type.
