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 r aised. 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 sew ing:
Turn the main power to OFF and unplug the machine.
If you restart the machine, follow the instructions for operating the machine correctly.
