Adjusting Thread Tension on Singer Sewing Machine: How To Thread Singer Sewing Machine

Proper thread tension is crucial for smooth and high-quality sewing operations on your Singer sewing machine. Incorrect thread tension can lead to a variety of issues, including uneven stitches, thread breakage, and poor fabric feed. To overcome these problems, it’s essential to learn how to adjust the thread tension on your Singer sewing machine.
Upper and Lower Tension Discs, How to thread singer sewing machine
The thread tension on your Singer sewing machine is controlled by the upper and lower tension discs, which work together to distribute the thread evenly. To adjust the tension, you’ll need to access these discs, usually located on the machine’s tension dial or presser foot.
To access the upper tension disc, you’ll typically need to lift the presser foot and turn the dial counterclockwise to release the tension. Then, move the disc to the desired notch or position, usually marked with numbers or indicators. Some machines may require you to lift the tension lever or press a button to access the disc.
For the lower tension disc, you may need to remove the presser foot or access panel to reach it. This disc is usually located near the machine’s take-up lever or bobbin winder. To adjust the lower tension, turn the dial clockwise or counterclockwise to increase or decrease the tension accordingly.
Some Singer sewing machines may have a different adjustment procedure, so be sure to consult your user manual or online documentation for specific instructions on your model.
Checking and Adjusting Thread Tension
To ensure your thread tension is set correctly, perform a simple test:
- Thread the machine with a scrap piece of fabric.
