 CAUTION

• This machine is equipped with a thread detection device. If the “Start/Stop” button is pushed before the 

upper threading is done, the machine will not operate properly. Also, depending on the pattern selected, 
the machine may feed the fabric even if the needle is raised. This is due to the needle bar release 
mechanism. At these times, the machine will make a sound different from that made during normal 
sewing. This is not the sign of a malfunction. 

• If the power is disconnected during sewing:

Turn the main power to OFF and unplug the machine. 
If you restart the machine, follow the instructions for operating the machine correctly.
