Question about Juki HZL-25Z

1 Answer

The machine seems to work fine when I am sewing two pieces of fabric together. The problem is when I was making double welt cording for an upholstery project. I was adding the second piece of cording and sewing down the center between the two cords and the machine made a noise like the needle was hitting the plate and froze. It looked like I bent the needle slightly so I fixed it and it just kept on doing the same thing. Upon further inspection it looks almost like the feed dog is slightly tilted and not perfectly centered in the slots it rides through. I am able to sew two layers of fabric without a problem, but the machine continues to jam when I tried to sew the double welting. Do I need to adjust the feed dog somehow?? My husband is pretty handy and wants to fix it so we would appreciate your feedback.

First you need to change the Needle to a heavy duty needle that may help a lot. You may want to check ur stitch settings as well. Sometimes work with a heavyweight fabrics or bulky items can throw ur tension and stitches off. So my just need to re adjust them. Manually sew(turn the non) the item first to get the machine going. Then slowly press ur petal.

SOURCE: skip stitch

The three most obvious causes (other than that of the machine possibly being slightly out of time) are:

1) Too small of a needle size - increase the size.

2) A needle that has a flaw / defect - change the needle.

3) Needle not inserted correctly, either not pushed all the way up into the needle bar, or not installed facing the correct place. On this machine, the small "scarf" in the needle (an indent just above the eye) shouldface the right side of the machine.

Properly balanced tensions are critical. The lower bobbin tension must be tight enough to pull the knots down. To which number is your upper tension set? It should be around three. Skipping stitches is an indicator of hook timing and hook/needle clearance issues.

My janome 9000 won't sew forwards it just moves on spot

Make sure the stitch length is set higher than 2. Also make sure the feed dogs have not been inadvertently dropped for darning. If the feed dogs are up and moving back and forth, they are working okay but may have a lot of lint and dust inhibiting them from biting the fabric.

Are you sewing very fine or slick fabric? Frequently, that will cause the fabric to slip under the presser foot. Check your machine to see if you can adjust the pressure on the presser foot. If not, then try laying a piece of wax paper or vellum with the fabric. It can be easily removed after stitching.

I have my machine threaded and it runs with no beeps however it is not sewing the material together

I'm wondering if you have the flat side of the needle in correctly. If your bobbin assembly is in the front of the machine, the flat side should be towards the back. Also, check to make sure your needle is ALL the way up in the needle clamp.

Someone gave me a Life style Pfaff sewing machine and I don't have the manual. I would like to know how to use the rolled hem foot and need to purchase a pipping foot. A foot to make pipping, 1/4 -...

I would suggest you contact Pfaff firstly to see if you can obtain a manual, its always worth having the one for your machine. I presume you are in the USA? if yes, go to or ring toll free 1-800-446-2333 Monday-Friday 8:00a - 4:00p CST or email
or go to then choose your own country then go to "contact us". and find the details.

Using a rolled hem foot is the same on all sewing machines, you are introducing the cut edge of the fabric into the front of the foot and it rolls the cut edge twice, as you seam over it. Its fiddly, you need a straight trimmed edge, and you have to keep the same amount going into the foot for it to work. You can either straight stitch or do a small zigzag over the fabric. Getting it started is the hardest bit because you need something through the foot to stitch on so it doesn't just get pulled into the hole on the needle plate.

try this link for a bit more info on this, some machine makes sell a 2mm, 4mm or 6mm foot for different weights of fabric and finishes. You can buy accessories for your pfaff from or from Pfaff. Pfaff website even has free projects and a newsletter for customers.

Just put the foot on, lower the pressure foot onto the edge of the fabric, do a couple of straight stitches, then raise the pressure foot and pull the fabric back an inch, so you have something to hang onto at the back, then put 1/4 of fabric into the open part of the foot, hold it there, lower the pressure foot and start stitching, keep a bit of fabric turned in in front of the foot so you help it go into the foot and try to keep it a constant width, trial and error, you'll soon get the hang of it.

Piping can often be done with your zipper foot, you just want to encase the piping cord with a bias cut fabric strip and stitch as close to the edge of the cord as you can to hold it nice and tight. Then put the piping strip between two pieces of fabric and again stitch close to the cord so the first line of stitching doesn't show. Some machines, the zipper foot will have a guide so you can squeeze the cord up against the foot. Here is a link for piping techniques and covering cord

Just cut the bias strip width to suit your cord width, join the bias strips together if you want lots of length, then wrap fabric around the cord, right side out, put it under the zipper foot and stitch through the fabric as close to the cord as you can, on some machines you can adjust the needle position to get close but check your manual for help on this, you don't want to strike the foot, just sew up close to it.

I haven't done double piping, but I presume you would sew two layers of piping on top of each other?

I've got a old "Sewing Soft Furnishings" text book that I found at the op shop for $2, the images are daggy but the techniques don't change, most furnishing stuff is just taking measurements, adding seam allowances, and sewing straight seams, so the machine doesn't have to be fancy, or need lots of accessories, just know-how. What you do need is a strong machine to sew upholstery fabric, many domestic machines just won't handle heavy weight fabrics too well. Large sized needles 110 size will be important too.

I'd suggest you try one of Debbie's free pillow guides as a start , go for something without a zipper at first, and once you've made a couple of easy pillows, your confidence will grow.

Good luck with your Pfaff and enjoy your sewing.

What tension should I use for fine materials? I have a Toyota RA41

The proper tension is a tension that locks the threads together tightly (you don't see a gap in your seem when you pull the two separate fabric pieces apart after sewing). But the biggest problem I see is when people have the thread tension so tight that it puckers the fabric as it's sewn. Thread tension is a balancing act between three forces top tension, bobbin tension, and fabric

Hope this helps...

One thing to try is that the button hole lever has not moved to the front or back of the guide, make sure that it is in the direct middle. Sometimes they get moved when you take out or insert fabric. If, that is not it, call Singer and find out if there is a problem with this model, because if it is maybe you can exchange it. Their phone number, 1-800-4singer

Sewing machine will not advance the fabric

Have you tried adjusting the tension as you sew?
Use a scrap piece of the same fabric, (doubled, etc to simulate piece you'll be working) and adjust the tension as you sew. Sometimes, that's all it takes.
