Threading Need threading diagram

Search the internet for:

Make + Model + the word "Manual" or "threading diagram"

or contact manufacturer support.

There may even be some videos on YouTube.

you need to provide the name and model of the overlocker, so someone can help find a threading diagram

Search the internet for:
Manufacturer + Model + the word "Manual"

or search YouTube videos for "sewing machine threading." You may not find your exact machine, but many machines have similar threading patterns. Be sure to raise the presser foot before threading the upper thread so it will seat properly in the tension disk.

If the thread is breaking at the needle, it could be several problems:
Threaded incorrectly--#1 cause
Upper tension too tight
Install a brand new needle compatible with the fabric & thread
Make sure the thread is not too large for the needle eye
Avoid old, fuzzy, bargain bin thread

contact bernina and see if they have a diagram for threading

I found two things for your consew, but neither of them have threading information. Generally, you thread a serger like this. Upper Looper, Lower looper, needles from right to left. If you ever break a thread... remove all other threads and begin again from the upper looper thread. (I know... it's a pain) Here's a video that is NOT your machine but explains pretty well.

contact husqavarna customer service about a manual

they have some threading diagrams at sewusa.com

The inside diagram is for the loopers. For the needle threads, just follow the color coded dots.

Go sewusa.com for a free threading diagram.

I believe this is the manual that you need.
