When filling bobbin, the needle goes up and down, causing thread to tangle and not fill bobbin. How do I release the needle action?

To stop the needle from moving up and down while filling the bobbin on a Singer Quantum 9240, ensure the bobbin winder clutch is properly disengaged. If the needle continues to move, old sticky grease may be causing the clutch to stay engaged. Remove the handwheel, clean the shaft and handwheel sleeve with isopropyl alcohol, apply a small amount of light oil, and reassemble. This should allow the clutch to disengage the needle mechanism during bobbin winding.
