How do I get the correct tension on my Elna 792D 4 thread overlocker?

ALWAYS Raise the presser foot when threading the machine. Give each thread and extra little tug when threading the tension disks so it seats completely. The midway point on the tension disk is the standard factory setting when using the standard thread weight, however, with use, age, and thread weight that setting may change. So, the user can use the midway point as a starting point for the basic overlock stitch but will need to make adjustments to get the correct tension. When testing your tension, it works best to use the 4 thread colors so it is easier to identify which thread is misbehaving. When you become familiar with your machine and how the stitch looks, it is easier to identify which thread is which.

Remember that the tension settings will also determine the stitch you are trying to create. A basic overlock will generally have the tension set around the midway point, however, when changing to a rolled edge or some other stitch, certain tensions will be increased or decreased in order to create that particular stitch.

Make sure the lower looper thread is seated properly in the tension disk. (RAISE the presser foot. Grasp the thread between the thread tree and the tension disk and with the other hand, grasp the thread below the tension disk and give a little tug.) When threading, always RAISE the presser foot so the tension disks are released.

If the lower looper thread is still too loose, set it to a tighter setting until it creates the stitch you want.

I need to adjust my baby lock and just can not understand how it works,the tension Dial with the Blue,Green,Orange,Yellow and purple, What is the right tension for light weight Fabric for the side sea

Try setting up your machine with the 4 different thread colors as the guide--use yellow thread in the yellow guide, blue in the blue, etc. This is a good way to figure out what is not working with your tension dials. To start out with a 4-thread stitch, set the tension dials at the midway point on each and then test your stitch. You should be able to see which thread colors are off. If one color is wrapping over the edge of the fabric, then that tension is too loose and the opposite thread may be too tight. The tensions are correct when the threads meet in the middle of the fabric. It's a matter of sitting down and playing with it to see what happens when you make changes to the settings. Also, one particular setting that works on a particular fabric may not work on another, so learning how to test and adjust is a big part of using a serger.

As for stitch length, that is mostly a personal decision. The shorter the stitch length, the closer the stitches will be.

Need basic settings for Baby Lock BL450 Serger. Any idea where I can get it?? My book was lost. The threads don't wrap around the edge of the fabric. I've re-loaded 3 times following the diagram on...

Hi GailKelley,
I have the same model serger. I will make a copy of the stitches and figure out how to get it to you. I recently took my serger out of storage to start some projects. I always struggle threading it but love the look of the stitches when it is set up correctly. Be in touch. MnFriend

I don't have a manual for my Baby lock Pro line model # BL4-738 NS. It was given to me and I have threaded it accordingly to the diagram on the machine but it won't pick up the stitch.

You will have to order the manual from a Baby Lock dealer.

This model may have to be threaded in a certain order.

Try raising the presser foot and setting the tensions to zero.

Turn the handwheel so the upper looper (the curved one) is at it's highest position - there may be a mark on the side of the serger where you align the handwheel for this.

Thread the upper looper and then the lower looper and then the needles.

Pull the threads under the presser foot and toward the side of the serger.

Set the tensions back to 4 - 6, lower the presser foot.

Hold onto the thread tails and gently press the power pedal to begin a thread chain before serging fabric.

Factory settings for stitch length and width dials

I hope you have not left this machine for a year! (If you haven't used it, feel free to send it to me!) Since the tensions on this machine are automatically set with the automatic thread delivery system, check to see if you have stitch dial set for an overlock or a flatlock stitch (which is what you're getting now).
