Operating Instructions
This section covers the basic operation of your Necchi NC-204D sewing machine.
1. Threading the Machine
- Winding the Bobbin: Place a spool of thread on the spool pin. Guide the thread through the bobbin winding tension disc and around the bobbin. Place the bobbin onto the bobbin winder spindle and push it to the right. Start winding by pressing the foot controller or start/stop button. Stop when the bobbin is full.
- Inserting the Bobbin: Open the bobbin cover plate. Insert the wound bobbin into the bobbin case, ensuring the thread unwinds in the correct direction (usually counter-clockwise). Guide the thread through the tension spring and into the thread guide. Close the bobbin cover.
- Threading the Upper Thread: Raise the presser foot. Place a spool of thread on the spool pin. Guide the thread through the upper thread guide, down into the tension assembly, up and over the take-up lever, and down to the needle. Use the automatic needle threader for easy needle threading.

- Bringing Up the Bobbin Thread: Hold the upper thread lightly. Turn the handwheel towards you to lower the needle into the needle plate and then raise it. The upper thread will catch the bobbin thread, bringing it up through the needle plate opening. Pull both threads under the presser foot and towards the back of the machine.
2. Stitch Selection and Adjustment
- Selecting Stitches: Use the numerical keypad and direct stitch selection buttons on the control panel to choose your desired stitch pattern. The selected stitch will be displayed on the LCD screen.
