Key Features Relevant to Threading:

  • Built-in Needle Threader: A handy tool that simplifies the needle threading process, saving time and reducing eye strain.

Preparation Steps Before Threading:

  1. Clean the Machine: Begin by cleaning your Singer M1500. Remove lint and debris from the bobbin area and the feed dogs. This prevents thread jams and ensures smooth operation.
  2. Inspect for Damages: Check the needle for any bends or bluntness and replace it if necessary. A damaged needle can lead to threading and sewing issues.
  3. Choose the Right Thread and Bobbin: Select a high-quality thread and an appropriate bobbin for your sewing project. Using the wrong type can cause threading problems.

Basic Steps to Thread a Singer M1500 Electric Sewing Machine

Threading a Singer M1500 sewing machine is a straightforward process that, when done correctly, sets the foundation for successful sewing projects. Here’s a detailed guide:

1. Place the Thread Spool:

  • Place your thread spool on the spool pin.
  • Ensure the thread unwinds in the correct direction as per the machine’s manual.

2. Guide the Thread:

Lead the thread through the designated threading path on the machine. This typically involves passing the thread through a series of hooks and tension discs.

3. Threading the Bobbin:

  • Wind the thread around the bobbin winder tension disc.
  • Place the bobbin on the winder, and push the bobbin winder to the right to engage.
  • Start the machine to wind the bobbin, then disengage the winder.

4. Inserting the Bobbin:

  • Place the wound bobbin in the bobbin case, ensuring it unwinds in the correct direction.
  • Thread the bobbin tail through the slit in the case, leaving a tail of a few inches.

5. Threading the Needle:

Use the built-in needle threader or manually thread the needle. The thread should pass from the front to the back of the needle eye.

6. Drawing Up the Bobbin Thread:

  • Hold the needle thread loosely, and turn the handwheel towards you to lower and then raise the needle.
  • This action should bring up the bobbin thread. Gently pull both threads to have equal lengths.

7. Threading the Upper Thread:

  • Raise the needle to its highest position and lift the presser foot.
  • Place thread on the spool pin and draw it through the upper thread guide.
  • Guide the thread around the thread guide and through the tension module.
  • Pass the thread through the take-up lever and down behind the needle clamp guide.
  • Thread the needle from front to back and pull 6-8 inches to the rear.
  • Trim the thread with the built-in cutter. Remember to turn off the power before

8. Raising the Bobbin Thread:

  • Hold the upper thread with your left hand. (Step 1)
  • Turn the handwheel toward you (counterclockwise) to lower and then raise the needle.
  • Gently pull the upper thread to bring the bobbin thread up through the needle plate hole. (Step 2)
  • Lay both threads to the back under the presser foot. (Step 3)

Note: If lifting the bobbin thread is challenging, check for any thread entanglement with the hinged cover or the Removable Extension Table.


9. Adjusting Thread Tension on Singer M1500:

  1. Basic Setting: Set the tension dial to “4” for straight stitch sewing.
  2. For Straight Stitches: Increase tension (turn dial higher) if stitches are too loose. Decrease tension (turn dial lower) if stitches are too tight.
  3. Zigzag and Decorative Stitches: Adjust tension to allow a small amount of upper thread on the bottom side of the fabric.
  4. Lower Thread Tension: Typically, no adjustment needed for bobbin tension.
  5. General Tips: Balanced tension is ideal for straight stitch construction. Most sewing falls within the “3” to “5” tension range.
  6. Decorative Sewing: For zigzag and decorative stitches, use lower tension. Aim for a nicer stitch with an upper thread showing on the bottom side.
