Serger not cutting right

My Bernette 334 DS is not cutting right. It seems to be eating the fabric, kind of chewing it up. I replaced the lower knife with what I thought was a new blade. I have adjusted the level. Still eats the fabric and does not look neat at all.
I thought that maybe this is a very simple problem to fix.
Please let me know what I am doing wrong!
Thanks so much,
Deborah

Your knives may be blunt and need sharpening or replacement.

Check also if the knives are aligned properly. Remove the material and turn the handwheel slowly. The knives should pass each over like a pair of scissors and there should not be any cap between the blades.

If everything seems to be okay and it still does noet cut tne material, replacement is the only option.

Hi,
I have found this info...it mentions both threading and changing the knife width. I hope it is useful.

This happens with other brands as well.

Hold on to the threads behind the presser foot and hand walk the first two or three stitches.

Some like to use a leader/spider.

Fold a scrap and stitch to the edge and then **** with the fabric you want to sew.

Remove the leader and use over and over and soon the leader threads will resemble a "spider".

How do I set my Bernette 334D to overlock thin T-shirt material?


Thin, light-weight fabrics present some issues with sergers, ie the fabric tunnels with the stitching. Usually, it is better to use a narrow seam. Also, a stabilizer (wash-away) or even adding a strip of thin paper (toilet tissue, adding machine tape, etc) to the seam will help the fabric hold its shape when stitching. I have also sprayed & ironed heavy starch on thin fabrics to help stabilize.

How do I take the knife down?? I don't want to use it.


Usually, the upper knife can be lifted, but that is usually for the purpose of cleaning or threading. HOWEVER, it is recommended to never use the serger without the knives. What frequently happens is the fabric gets too far to the right and then interferes with the loopers. When that happens, the loopers can be damaged/broken. If you don't want to cut, just guide the fabric edge slightly to the left of the knife action so the fabric is not cut.

Pushing material away, but still overlocking


It is difficult to tell what exactly is happening with your serger.

First thing--make sure you RAISE the presser foot BEFORE you thread any of the threads. This releases the tension disks so the threads will seat properly. You may need to remove all the threads and rethread from the beginning, making sure you thread each in the proper order. Start out with the thread tensions set at the ideal setting--usually the halfway point between the high & low numbers. From there, you will adjust them to even up the thread tensions.

Are you actually trimming off some of the fabric as it is stitching? If so, you might try increasing the cutting width (moves the cutting edge further toward the right) so that there is more fabric caught within the looper threads. It also appears that the looper tensions may be too loose. Try tightening the upper and lower looper tensions so less of the thread loops don't fall off the fabric's raw edge.

I recently got an older bernette 334 ds serger and it doesnt look like it hss ever been used. i went to plug it in and run it and nothing happened only light came on


If it's old and has never been run, it will need a proper service fro the parts that have become immobile due to the lubricant "gumming up".

Off to the sewing machine shop for you!

My serger keeps rolling the edge as I serge. I've tried to make several adjustments. Where do you get instruction manuals. Is it online?


Possibly you need to adjust the knife. It sounds like the knife is positioned too far to the right which is causing the cut fabric to extend further than the edge of the stitching. The thread chain is probably so tight against the edge of the fabric that it is folding it over.Move the knife a little to the left and try it again. If the thread chain is hanging past the cut fabric then the knife was moved too far to the left.

I have a Husqvarna serger and when I try to serge and cut through 3 thicknesses of sweatshirt fleece it won't cut. I have replaced the cutter and it still won't cut. The same happens when I sew on polar...


I really need to know what kind of serger you have , if it is the 905 910 or the 936 series take a look at the large headed screw that holds the knife in place. if you are doing fleece it will cause a lot of build up of lint behind this screw and not allow the knife to go all the way up and down causing it not to cut multi layers of fabric, and if this is the case it probably needs to go the an authorized tech for a thorough cleaning

I have a pfaff Hobbylock 4860 serger. I got it serviced about 6 months ago but never used it until about a month ago. Now it will not cut my fabric as I serge. What should I do?


If it won't cut then you need either a new upper knife or lower knife. One or both has gotten dull or nicked up. The place you got it serviced or any dealership should be able to order new knives for it.

Trouble starting a seam


Evolve is a serger and can't sew backwards. Start on a scrap and then onto fasion material and then cut off scrap. You'll have to use fray check where cut or it'll pull out. I'd ask your dealer. It shouldn't do this. Do you start w/ a thread chain? You have to except for the chain or cover stitch where you have to start on material.
