How can the lower-thread tension be adjusted to suit Bobbin-Play Sewing?

Use the multifunction tool included with the machine. Hold the bobbin case stop with your left hand and turn the handwheel clockwise with your right hand until the setting tool can be slid over the lug at the slider. Refer to 'Preparation,/Lower Thread Tension' chapter in the user manual. Slide lug to the left (slacken) depending on the thread used. Reset to lower thread basic setting (red dot in the bobbin door) after Bobbin-Play Sewing.When applying this technique, we recommend increasing the upper thread tension and testing before starting on the project.
