Frequent troubleshooting topics

Detailted causes and remedies for common troubleshooting topics are described below. Be sure to refer to this before contacting us.

Upper thread tightened up

■ Symptom

  • The upper thread appears as a single continuous line.
  • The lower thread is visible from the upper side of the fabric.
  • The upper thread has tightened up, and comes out when pulled.
  • The upper thread has tightened up, and wrinkes appear in the fabric.
  • The upper thread tension is tight, and the results do not change even after the thread tension is adjusted.

■ Cause

Incorrect bobbin threading

If the bobbin thread is incorrectly threaded, instead of the appropriate tension being applied to the bobbin thread, it is pulled through the fabric when the upper thread is pulled up. For this reason, the thread is visible from the right side of the fabric.

Remedy/check details

Correctly install the bobbin thread.

  1. Press and raise the presser foot lever.
  2. Remove the bobbin from the bobbin case.
  3. Place the bobbin in the bobbin case so that the thread unwinds in the correct direction.

• Hold the bobbin with your right hand with the thread unwinding to the left, and hold the end of the thread with your left hand.

Then, with your right hand, place the bobbin in the bobbin case. A

If the bobbin is inserted with the thread unwinding in the wrong direction, sewing will be done with an incorrect thread tension.

d While holding the bobbin in place with your finger, pass the thread through the slit in the needle plate cover.

• Hold down the bobbin with your right hand, and then pull the end of the thread around the tab with

  1. Tab
  2. Hold down the bobbin with your right hand.

■ Remedy/check details

Remove the tangled thread, and then correct the upper threading. a Remove the tangled thread. If it cannot be removed, cut the thread with scissors.

  • For details, refer to “Cleaning the race” on page A-2.b Remove the upper thread from the machine.
  • If the bobbin was removed from the bobbin case, refer to “Installing the bobbin” in the “Basic operations” section and “Remedy/check details” in the section “Upper thread tightened up” on page A-5 to correctly install the bobbin.

c Refer to the following steps to correct the upper threading. Raise the presser foot using the presser foot lever.

1 Presser foot lever

→ The upper thread shutter opens so the machine can be threaded.

• If the presser foot is not raised, the machine cannot be threaded correctly. d Press (Needle position button) once or twice to raise the needle.

→ The needle is correctly raised when the mark on the handwheel is at the top, as shown below. Check the handwheel and, if this mark is not at this position,

1 Mark on handwheel e While holding the thread lightly with your right hand, pull the thread with your left hand, and then pass the thread behind the thread guide cover and to the front.

  • Symptom 2: The upper thread appears as a straight line on the right side of the fabric.
  • Symptom 3: The upper thread is visible from the wrong side of the fabric. (Refer to illustration below)
  • Symptom 4: The bobbin thread appears as a straight line on the wrong side of the fabric.

  4. Right side of fabric
  5. Bobbin thread
  6. Upper thread visible from wrong side of fabric

■ Cause/remedy/check details

… Cause 1

The machine is not correctly threaded. <With symptoms 1 and 2 described above> The bobbin threading is incorrect.

Return the upper thread tension to the standard setting, and then refer to “Upper thread tightened up” on page A-5 to correct the threading.

<With symptoms 3 and 5 described above> The upper threading is incorrect.

Return the upper thread tension to the standard setting, and then refer to “Tangled thread on wrong side of fabric” on page A-6 to correct the upper threading.

Note

• If the upper threading and bobbin threading are incorrect, the thread tension cannot be adjusted correctly. Check the upper threading and bobbin threading first, and then adjust the thread tension.

… Cause 2

A needle and thread appropriate for the fabric are not being used.

The machine needle that should be used depends on the type of fabric sewn and the thread thickness. If a needle and thread appropriate for the fabric are not being used, the thread tension will not be adjusted correctly, causing wrinkles in the fabric or skipped stitches.

• Refer to “Fabric/Thread/Needle Combinations” in the “Basic operations” section to check that a needle and thread appropriate for the fabric are being used.

… Cause 3

An appropriate upper tension is not selected. The setting selected for the upper thread tension is not appropriate.

Refer to “Setting the thread tension” in the “Basic operations” section to select an appropriate thread tension.

The appropriate thread tension differs depending on the type of fabric and thread being used.

* Adjust the thread tension while test sewing on a piece of scrap fabric that is the same as that used in your project.
