Slide back the cover.Press the white button to the left of the bobbin.
Press the foot pedal to wind on the thread.
Load it with the amount of thread you require.
The clear bobbins are marked to indicate fill.
If you have leftover thread when through, or if there is a problem, the bobbins unscrew so that thread can be removed all at once, rather than spun off.
Sorry, I can't say more, I haven't used mine in quite a few years.

I can answer this question...
How do you wind the bobbin on the singer 626 model?
