From "Serge With Confidence" by Nancy Zieman:

Set the machine up for a 3-thread rolled edge. Normal width; length 1 - 2.

Use Woolly Nylon in the loopers & regular thread in the needle.

Lock or disengage the cutting blade.

Guide fabric along the right edge of the presser foot.

Stretch and equal amount from fron to back while serging.

Lower the differential feed, if available to about 0.6.

Serge at a slow to moderate speed.

Practice with scraps first.

After serging, gently stretch & release the fabric edge after serging.

This guy has shipped to everywhere. I am sure if you email him, he would be willing to mail you a copy in the UK. These manuals are hard to find, so any source is a godsend!

May be one of three things:
A) foot pedal may have burnt out (this is common-is this perhaps where the smell was coming from?)
B)The belt inside the machine may have worn out
C)You may have actually worn out he motor, depending on how long you have had the machine.
Suggestion for all three-take it to your reputable sewing machine repair person. It will likely cost about $100. I take my machine in every 6 months for a 'tune'up', and it has proven to be a wise move, since I use my overlock frequently.

Replace the needles and choose size according to the thickness/weight of the fabric you are serging.

You may have to re-thread, here is a video from Threadbanger - http://www.allbrands.com/products/abp08027.html

I suggest also setting the stitch length to about 2 (very close together). When the stitch is shorter, it seems to be able to give a little more. I also use woolly nylon, but I still had the problem (especially when hemming). This is how I solved my problem....

hi , i have one the same and yes you do have to force itjust that bit further on the [length] dial till u see a green triangle, it is just past the 'o' then select the green stitches you want, i hope this helps happy sewing from georgi

You have to thread the needles last.

1 - Take the threads out of both needles.
2 - Thread both loopers according to the diagram on your serger.
3 - Thread the needles.

If this fails, you need to bring it to a pro for service.

If the manual does''t say anything about oiling machine don't. Usually when you take in for a service it is done then. But always keep it clean with a brush.

I am disappointed that you tricked me into asking for your help that you so advertised and then I get this answer to click on a "premium plan" I can pay for. What a cheap trick! HAVE A GREAT DAY IF YOU TRULY FEEL GOOD ABOUT YOURSELF.............

You need to fit a rolled hem plate

Clean in between you tension plates of your tension units and rethread making sure your cotton runs between the tesion discs.

BERNINA 800D

wont pick up thread from bobbin

it sounds like the machine isn't threaded correctly, start again and see how you go
