SOURCE: thread wont overlock

When the thread breaks too often, try these, that goes for all sewing machines
1. Replace the needles,
2. Loosen slightly the tension of the needle threads.
3. The top threads are to thin,
4.The sewing (rotary) hook or looper, has burs,
5. Wrong threading

SOURCE: sharpen the cutting blades

You really can't sharpen them...you have to buy new ones.

I am trying to figure out how to disengage the blade on a BL4-738D Pro line serger. I do not have the book and not figure out how to do it.

Most serger upper blades can be "flipped" out of the way by pushing in and rotating it at the same time. HOWEVER, remember it is not recommended to run the machine with the blade deactivated. The loopers can be damaged/broken when they contact fabric that has not been trimmed.

Can I stop my semco 750 overlocker cutting the material when I'm sewing


You should be able to disengage the cutting blade. Probably a button that you push in then rotate anti clockwise, this will turn the blade down under the machine therefore not cutting the fabric.
Good luck

Overlocker Bernette


If this is new it will still be under guarantee so have it checked out. It sounds like a badly aligned or blunt upper blade.
Overlockers will sometimes struggle with thick fabrics and putting something to help keep the foot level to " jump the bump" will often help, discuss that with the sleasperson too.

I accidentally sewed over a pin and now the moving


Disengage and then engage the blade to see if this will reset the position of the blade.

You could replace the blade - this should be in the manual or you may need to take the machine in for service as replacing the blade may or may not be all that needs to be done.

I want to know which knob I use to make the stitching narrower


there are generally two variable controls .. one adjusts the stitch length (distance between stitches measured in stitches per inch) ... the second is stitch width .. that adjusts how far the zigzag moves left and right .. thats usually just a number from 0 to 10 or so .. 10 would be maximum width .. 0 would be used for straight stitch ..
so you need to adjust the stitch width control to make the stitching narrower .. the controls are called different things on different brand sewing machines .. if you have the brand and model number then there may be instruction booklets available ...

How do you get the blades to cut on a hobbylock 794 serger


It should just cut. Don't know too much about this machine as I'm new owner, but from what I can gather, either you need a new blade, or the upper knife is disengaged. The metal knob inside the threading area should be turned downwards, engaging the upper knife. The upper knife doesn't usually need replacing unless damaged, apparently. Hope this helps somewhat.
