Insert the plug of the foot pedal into the designated "FOOT PEDAL" port on the back of the machine. The foot pedal provides an alternative method to control the machine's operation.
3. Threading the Machine
Proper threading is essential for correct stitching.
Upper Threading:
- Place a spool of thread on the spool pin.
- Guide the thread through the first thread guide.
- Pass the thread through the tension control dial.
- Guide the thread through the take-up lever.
- Thread the needle from front to back.
Bobbin Threading:
- Slide the bobbin cover plate to the left to open the bobbin case.
- Insert a wound bobbin into the bobbin case, ensuring the thread unwinds in the correct direction (usually counter-clockwise).
- Pull the bobbin thread through the small slot in the bobbin case.
- Close the bobbin cover plate.
- Turn the handwheel towards you to lower the needle, catching the bobbin thread. Pull both upper and bobbin threads to the back under the presser foot.
