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 off the main power switch and unplug the machine.
- If you restart the machine, follow the instructions for operating the machine correctly.
