I have been teaching a sewing class to some young girls. I believe one of them adjusted the thread tension. I am doing a zig zag stitich and the bobbin thread is showing on the top stitch.

Check tensions again, review the manual. Could be threaded wrong or bobbin not correctly wound. These are common solutions to this problem.

Need to now where to put tentions to sew sweat pants.


use a couple of pieces of waste material the same as the sweat pants material and sew about an inch long
adjust the needle tension and do it again
repeat the exercise until the top and bottom thread joint at the middle of the two pieces of the material
tension settings on the machine are a loose guide as the thread thickness, material thickness and needle size all have a bearing in the tensions of the thread
so practice and adjust prior to sewing is the way to go

Loose underthread and no zig zag


Lower thread tension can be adjusted by tightening (clockwise) the small screw in the bobbin case. The specifications call for 12-20 g resistance when pulling the thread slowly. I suggest tightening in increments of 1/8 turn and trying the machine each time. Also, mark the position of the screw in its original position should you need to return to the original setting and start over (use a piece of tape and place a mark where the slot in the screw is). I don't understand what you're saying about the zig zag problem.

Sews straight when on zigzag


it's possible the zig zag gear or cam could be worn or damaged
and the machine should be checked to see for sure what's happened.

The thread underneath when sewing is too loosed


Usually thread too loose on the bottom is caused by the upper tension being too loose. The top and bottom tensions work together with the top thread making the underside of the stitch seem too taunt or too loose and the bobbin thread causing the top side of the stitch to be loopy or too tight. Select a large zig zag stick and sew a couple of inches. Then examine the stitch. It should look identical on both sides. Look to see which side is drawn too tight, the zig zag being smaller on that side with threads from the bottom threads pulled through. Then adjust the two tensions so that they make a uniform, identical stitch.

Also, when the bobbin tension is right you can hold the bobbin dangling by the thread and it won't spool out to the floor but will let loose a bit with a slight flick of the wrist. Too loose it will just spool out. Too tight and it won't drop at all. When you get that set right then do the above zig zag test to see where the top tension should be set.

I'm sewing a zig zag stitch and the underside is a perfect zig zag and the upper side looks like it should be the underside....how can I fix this so that the beautiful zig zag is on the top?


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...

I cannot get my tension adjusted correctly. I have lost my manual. Can you give me some help. Also, do I need a separate foot for the zig zag stitch.


usually a tension of 3 or 4 is good
only if the presser foot not is not made for zig zag--all the presser foot's that I've seen on new machines do straight stitch & zig zag,, if the opening in the foot is large then manually try a zig zag stitch to see

What are the settings for regular sewing, I do not have a manual. It has 3 knobs on the front and 1 on top? This might have something to do with my problems.


The three front dials are as follows....left to right-Stitch width, type of stitch, and stitch length. The dial on the top adjust the top tension.

For straight stitch you want 0 stitch width, straight stitch, 3 for stitch length.

For zig zag you want turn your stitch width to how wide you want the zig zag, choose zig zag stitch, and choose how close you want the stitches to be on the stitch length dial. Practice on a piece of fabric. Usually for zig zag you will want to loosen your top tension a little bit.

Suddenly zig zag stitch not working?


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.
