All is fine when I sew a straight seam, but when I zig-zag . . . urk!
Bobbin thread is picked up fine on the left side of the motion (zig) but never picked up on the right side (zag). What's the deal?
Checked, re-checked, pulled apart (as much as was wise!), cleaned, oiled, re-threaded. Checked, re-checked, pulled apart (as much as was wise!), cleaned, oiled, re-threaded.
All is as it should be - but the picture that Brother showed under the faq title "Why won't the machine pick up the bobbin thread?" showed single missed stitch. Imagine, if you will, a whole line of missed stitches.
/\/\/\/\/\/\/\ is how it SHOULD look.
----~~~snarl--snarl------ is how it DOES look

ok.... let's do some more troubleshooting. Are you using the original bobbins, or universal? what size needle are you using? What type of fabric? and thread? Is the shuttle tight or loose (bobbin casing) ? what tension settings are you at?

So your set up to sew zig/zag and only get the zig or the zag : )
Could be top thread tension is too high. Switch to a straight stitch and reduce tension until top thread starts to appear on bottom. Then go back to zig/zag and see if it sews properly.
If still dropping stitches, check the needle is not bent and is fully inserted into the holder. Clean the bobbin, hook, and race per machine instructions. Try reducing the stitch width and see if that makes any difference. If still not right then timing may be off.
Joe, you might try a larger needle than you're using. You might also want to try a larger leather needle. You machine should take needles up to a size 18.
It sounds like the needle you're using is having a problem picking up the bobbin thread, and that might solve it.
Try installing a brand new needle. Perhaps the needle is bent or damaged so it is not able to catch the bobbin thread. Also be sure the needle is installed with the flat side facing the correct direction.
If it is still not catching the zig-zag stitch, you may need to take it for service.
put in a new needle rethread the machine top & bobbin--use every thread guide make sure the zig zag settings are correct it's also possible that the machine could have a worn or damaged gear or cam--which would have to be checked at a sewing machine shop
it's very possible that the machine is slightly out of time & needs to be service at a sewing machine shop is the fabric & thread & needle compatable with each other? did you use every thread guide when threading the machine? is the bobbin in correctly? is the bobbin warped?
FIRST > Make sure your bobbin case is threaded correctly...
NEXT For normal straight sewing the top tension should be around 5, for zigzag or satin stitch you need to lower your upper thread tension a bit. Try it at 4, if it still pulls your bottom thread to the top try it at 3 etc...
Because it is almost a straight stitch but the needle continues to move in a zig zag fashion is reason to believe it is in a long stitch. By changing the number of stitches per inch there will be a very noticeable looking zig zag stitch.

ok.... let's do some more troubleshooting.
Are you using the original bobbins, or universal?
what size needle are you using?
What type of fabric? and thread?
Is the shuttle tight or loose (bobbin casing) ?
what tension settings are you at?
did you check the hook race? make sure there is no thread caught in it
