I am sewing leather and have the settings correctly for leather. This is a lambskin and very thin. It won't feed properly and the bobbin thread either breaks or can be pulled out, so the stitch does not hold. I have rethreaded many times, put new thread on the bobbin, purchased Viking needles and new bobbins and bought expensive thread - but it hasn't worked.
Check the upper tension by lowering the presser foot and pulling on the thread through the needle. You should feel resistance. If not, take a stiff brush and clean out the tension disks/dials removing any loose threads or lint. If upper tension is ok, check bobbin tension by pulling thread through needle plate opening. You should feel resistance. If not, remove bobbin case and brush any loose threads or lint from the case, especially in the tension spring where the thread is snapped into place. You may need to use a sharp needle to dig in between the spring but be careful that you don't damage it.

Be sure you haven't missed a loop while threading the bobbin. If that's not it, check how well the bobbin is turning on the spindle. If it is threaded properly and you have cleaned it, I suspect you will find some damage to the bobbin that is causing it to bind on the spindle. If you have another bobbin, try it and see what happens. Post back to let me know what you find.

Sounds like the tension unit is at fault. First check the bobbin tension by removing the bobbin case. Use a half-full to 3/4 full bobbin. Be sure it is threaded through the bobbin case with thread hanging straight down with tension spring on top. Tie the stitch plate to the end of the thread. If the thread pulls the bobbin out, the bobbin tension is too loose. If it does not move when "jiggling" the bobbin, it is too tight (which is not likely based on your description). Small screw (through an open hole) on the side of the bobbin case adjusts the tension of the bobbin case. Left for loose and Right for tighter. Otherwise, contact local authorized Husqvarna Viking dealer for their assistance. You can find the closest dealer at the Husqvarna Viking website - http://www.husqvarnaviking.com/us Good luck.
SOURCE: My machine will not pick up the bobbin thread when
I read on line that the needle may be in backwards. Not sure that was true, but I did take it out and re-insert. The machine sews just fine.
Thank you,

Check that it is threaded correctly (both top and bottom) making sure that the upper thread is in the takeup lever and the bobbin is guided through the tension spring in the bobbin case. Watch the needle as you slowly turn the handwheel counter clockwise (toward you) and the needle point touches the fabric (make sure presser foot is down). Is the thread still relatively taunt? If it is loose, the upper thread tension unit does not have enough tension. Check the areas where the thread goes and make sure you remove any loose threads or fluff which could be inhibiting the tension discs from closing over the thread. If the tension unit still is not tightening enough, the tension unit may need to be replaced or the circuit board replaced. If everything is ok in the upper thread area, now look at the bobbin area. With no fabric, watch as the needle enters the bobbin area. Does it go down and the upper thread catch the bobbin thread and pulls it to the surface? Check for anything preventing the bobbin thread from being pulled up to the surface through the needle plate. If you have still not been able to resolve the problem suggest you take it to an authorized husqvarna viking dealer for service. You can locate a dealer near you by visiting the husqvarna viking website and clicking on the Dealer link on the left-hand side of the page - http://www.husqvarnaviking.com
Good luck.

This could be bad timing, or the needle is not in properly.
Make sure that the needle is pushed up all the way, and in the correct position. If the needle is too low, it will break.
Also, keep the bobbin case door open to see where the needle is catching.
