2.2 Power Connection
Connect the power cord to the machine's power input and then to a suitable electrical outlet. Ensure the power switch is in the "OFF" position before connecting.
2.3 Bobbin Winding
Before sewing, the bobbin must be wound with thread. Place a spool of thread on the spool pin, guide the thread through the tension disc for bobbin winding, and then around the bobbin. Place the bobbin onto the bobbin winder spindle and push it to the right. Start the machine to wind the bobbin evenly.
