Help with threading info for a Singer 5040c

I am out of town and did not bring my manual and my singer has started messing up. It was doing well on the zig zag stich, but I have changed the thread several times and I don't know if I have missed something. It is loose on the bottom and tight on top. And I have several things to finish before I go home, so would appreciate any help.
Thank you,

    Been sewing away on my Singer 5040c and all of a sudden the bottom thread is looping up all over and the tension is not right. When I adjust the tension knob, nothing happens! Help, why is the bottom thread all messed up? I made sure I threaded it correctly...????

I have the same problem. Driving me nuts. The tension dial is broken, as far as I can tell. Just craps out from time to time. Sometimes turning it on and off helps. I personally think it's a problem with the electronic controls.

Inherited Singer 755..need info on factory settings.. was sewing okay.. started having tension issues.. now it's a MESS! Help, please..

Remove the top thread from the machine.
Install a brand new needle.
ALWAYS RAISE the presser foot and rethread from the beginning.
Verify the top and bobbin thread follow the correct thread paths.

Top tension factory setting is usually around the midway point, but that may need to be changed depending on what you are sewing. Correct tension is when the two threads meet in the middle of the fabric.

Do you have your manual? Because it is almost always the top threading, either tangled thread or a bent or dull needle causing the problem. You can download your manual at for free and enlarge the detail of the diagrams for threading. I just hope that it is something simple and not your timing because that is not a do it yourself job, unfortunately. You can also call Singer customer service at 1-800-4singer. and get their advice. Good luck.
