Memo
● When the sewing machine is started or the 
handwheel is turned after winding the 
thread around the bobbin, the machine will 
make a clicking sound; this is not a 
malfunction.
● The needle bar does not move when you 
slide the bobbin winding shaft to the right.

used with this machine.

b Wound poorly
● The bobbin was designed specifically for this 
sewing machine. If bobbins from other 
models are used, the machine will not operate 
correctly. Use only the enclosed bobbin or 
bobbins of the same type (part code: SA156, 
SFB: XA5539-151).
● Make sure you turn the power off while 
threading the machine. If you accidentally 
step on the foot controller and the machine 
starts to sew, you could be injured.

● Make sure you set the bobbin so the thread 
unrolls in the right direction. If the thread unrolls 
in the wrong direction, it may cause the thread 
tension to be incorrect or break the needle.
