Tangled thread on wrong side of 
fabric
■ Symptom
*
The thread becomes tangled on the lower side of the 
fabric.
*
After starting sewing, a rattling noise is made and 
sewing cannot continue.
*
Looking under the fabric, there is tangled thread in 
the bobbin case.
■ Cause
Incorrect upper threading
If the upper thread is incorrectly threaded, the upper 
thread passed through the fabric cannot be firmly 
pulled up and the upper thread becomes tangled in 
the bobbin case, causing a rattling noise.
■ Remedy
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.

Refer to “Cleaning the Race” in “CARE AND 
MAINTENANCE” on page 338.
b
Remove the upper thread from the 
machine.

refer to “Setting the Bobbin” on page 54 and 
“Remedy” in the section “Upper thread is too tight” 
on page 343 to correctly install the bobbin.
