It helps to coordinate the HC handle with the needlebar each time after winding a bobbin or disengaging the HC finger from the wheel, to make it easier to stop with the needle in the up or down position as needed.

So, after winding a bobbin, tighten the clutch knob and turn the wheel until the needle is in its furthest down position. Loosen the clutch knob and turn the wheel again until the crank handle is also at the bottom of its rotation (make sure the needlebar doesn’t move while you’re doing this), and then tighten the clutch knob to begin sewing.
