TROUBLESHOOTING

Several solutions for minor problems are described below. If the problem persists, contact your nearest authorized 
dealer.

■

The thread was accidentally cut 
automatically and the bobbin thread is 
caught inside the machine (Only for 
machines equipped with the automatic 
thread cutting function)

a

Cut the thread near the fabric above the 
needle plate, and then remove the fabric.

a

Thread

b

Remove the bobbin, and then hold it out 
toward the left side of the machine.

c

Lower the presser foot.

d

Press the “Thread Cutter” button again, and 
then pull the thread out to the left while the 
thread cutter is operating.

■

The pattern is misaligned

Refer to “ADJUSTING THE THREAD TENSION” and 
increase the upper thread tension. If the pattern is still 
misaligned, reduce the tension of the bobbin thread.

Example: Decorative Stitch

a

Correct tension

b

The upper thread tension is too loose, or the bobbin 
thread tension is too tight.

■

The bobbin thread catches on the tension 
spring of the bobbin case

Sew with no tension applied to the bobbin thread. 
(Refer to “When tension is not applied to the bobbin 
thread” on page 6.)

 CAUTION

• Do not pull on the thread with excessive force, 

otherwise the machine may be damaged.
