You may need to adjust your tension dial with your fabric you are using and kind of thread, also adjust to thickness of fabric. Always use good sharp needles with your sewing and keep machine clean and oiled.

I don't own a Juki, but I am familiar with sewing knits and with differential feed. I would suggest getting some scraps of the knit you plan to sew and set the experiment with different settings until you eliminate any waviness. It's possible that you don't need t use the differential feed at all. Good luck and HTH.

It depends on the thickness of the material, the thicker the materials, the more tension.

It depends on how thick your batting is and what type of fabric you are using. It's best to practice on a scrap piece to get the setting right.

Your hook might not be timed correctly. Sometimes a thread or fabric jam can dislodge the hook. When your needle is just starting to move upward from its lowest position, the eye of the needle should be just below the hook.

Open the font of the serger and the instructions will be printed on the serger or on the door.

Raise the presser foot and set the tensions to zero when threading.

Turn the hand wheel so the upper looper (curved one) is at it's highest point and thread it first, and then the lower looper.

With some sergers you must thread in a certain sequence. This should be indicated in the instructions on the serger.

Set the tensions back to normal ( 4 - 6), lower the presser foot and run a length of stitching to see if the threads are knitted together as they should before you start serging your project.

Hi there,

Step 1. Set the upper tension tighter by turning the dial slightly to the right, or looser by turning the dial slightly to the left. (Or by using the electronic control if the sewing machine has one.) This adjusts the tightness of the main thread.
Step 2. Set the lower tension slightly tighter or looser using the dial or electronic control. This adjusts the tightness of the bobbin thread.
Step 3. Cut a small scrap of fabric, preferably the same type you want to sew with.
Step 4. Sew a few test stitches on the scrap. Examine the stitches to see if they’re too tight or too loose. The stitches should lie flat against the fabric, without pulling the fabric or making loops that stick out.
Step 5. Repeat Step 1 to Step 4 again as needed.

Good Luck!!
Thanks

Loops on the bottom of the fabric direct the problem to the top thread. Rethread again and make sure the thread goes through the tension discs. Lift the foot, because this is what opens the discs. When sewing and the foot is down, the discs should be closed and thus giving the upper thread the tension it needs.
