I gleaned this from a yahoo group that I read and found it very interesting, it might help someone in their hour of need!
Who knows what the Digital Ten sewing machine looks like? See the answer at the end of this message!

I am a repair-tech in training. I have added a few things to the list and here it is. I am still learning, so do not claim to know everything.
Sewing Machine Tune Up check list:
- Plug the machine into a power source that works.
- Lift up the presser foot lever before attaching the feet.
- Don't check the tension without putting the presser foot down.
- No matter if you've done it a million times, always double check that the needle is inserted correctly, flat side of needle away from last thread guide.
- Ditto the thread direction in threading the needle.
- Ditto the upper thread path.
- Even after doing the above, when all else fails, unthread the machine, take out the bobbin (consider winding a new bobbin), take needle out (and replace unless it's a new needle)
- Make sure thread on top and in bobbin are same brand. Yes, it matters!
Then rethread, re-needle, re-bobbin etc. You'd be surprised how many times this works on a fussy machine.
- BTW, while the bobbin is out, check the bobbin race for thread, needle bits, dust bunnies etc. Also, check the hook for burrs. Burrs cause skipped stitches or thread breaking. You may have to feel the edge with a finger nail to feel it.
- Remove needle plate and remove lint and fluff from feed-dogs.
- Check around hole in bobbin for smoothness. If not smooth, it could be causing thread breaking and other problems.
- Birds nesting or loose thread on the bottom of fabric is upper tension problem. Make sure machine is threaded properly and/or look for lint in tension rings.
Very important: Cheap thread (Coats & Clark, etc) causes more lint build up in the uneven way it is wound, so please don't use it! Gutermann & Mettler are the only ones I use.
Singer brand needles are made to bend when they hit something. A bent needle causes damage and burrs to the hook and creates thread breaking, skipped or dropped stitches. Schmetz needles are the only ones I use!
