Need to know how to thread an Elna Contessa 710 sewing machine

SOURCE: Elna Primula 410 Bobbin Winding Question

Wind the Bobbin
For the usual jobs, it is the best to use a medium sized thread.
2. Disengage the flywheel by unscrewing the coupling knob as far as it will go.

3. Place the bobbin on the bobbin winder, and push the bobbin winder to the right.

4. Pull out one of the spool pins and place the spool of thread on it.

5. Pass the thread through the bobbin winder tension discs, as indicated.

6. Wind the end of the thread around the bobbin by hand, in the direction indicated.

7. Wind the bobbin, at a medium speed by pressing lightly with a finger on the spool so as to stretch the thread better and thus fill the bobbin to a maximum. The full bobbin stops automatically.

8. Re-engage the flywheel by tightening the coupling knob.

9. Cut the thread and remove the bobbin from the bobbin winder by pushing the latter to the left.

SOURCE: Elna SU missing stiches and breaking thread

it sounds like the needle hook timing is out. You need to get the needle in the lowest position and measure the gap from the needle to the hook point on the bobbin shuttle. It should be 1/4". You will need to remove the foot and foot plate to be able to see. I use a 1/4" drill bit as a gauge. If you need to adjust it, you will need to remove the free arm cover to the right of the foot and loosen the 2 allen head screws that hold the drive gear. Adjust the gap, tighten the screws and retry. Usually if the needle catches the thread to early, it will make a bad stitch and the upper thread will break. If it catches to late, it will make thread loops and the machine will skip stitches. Good luck, these are a good machine and worth fixing. Phil
