Thank you for viewing. Sometimes the threader hook doesn't go into the needle's eye properly. You can get it through by wiggling it back and forth while pressing down on the operating lever. The following functions have been confirmed to work: Light on Bobbin winding Speed adjustment Reverse sewing Multiple test sewing patterns The purchase date and manufacturing year are unknown. I disassembled it for air blowing cleaning, thread entanglement removal, and lubrication of moving parts. (The air tool in image 7 is not included.) Please refrain from price negotiations in the comments. I welcome requests for price reductions. I will pack it with recycled materials. There is no instruction manual. Please consider purchasing only if you understand how to use it. JAGUAR Electronic sewing machine Serviced Sewing machine body sewing machine #usedinjapan #usedinjapan
