I have problems hemming garments with my new Bernina 009DCC coverstitch machine. When I try to sew a coverstitch hem to viscose-elastane jersey or other similar thin and stretchy jerseys, the machine somehow "pushes" the top layer of fabric forward. This causes the fabric to gather and form folds before I have even sewn more than a few inches.

Also I have to have the stitch length set to maximum (4) to get any decent looking stitch.

Other users of 009, are you able to hem this kind of fabrics? What stitch length do you normally use?

Terve filifjonka!
I find any of the very fine viscose elastane knit tops are harder to hem, the stretchier the harder they are to handle, and this is true of any coverstitch machine I think. You should not have to have your stitch length set to 4 to get a good stitch, I normally hem finer knits around 2.5 - 3.
I have tried another brand that I did not like before I got the Bernina coverstitch - and it had other issues but was far worse behaving with fine fabrics!

I think you need to look at reducing your presser foot pressure. Less pressure is needed for delicates to avoid shifting and stretching out layers. Same goes on a sewing machine. The manual shows you different recommended height settings for the screw for different fabrics.
So I'd loosen the screw a bit and experiment on scraps to find the right setting for best results.
You could also check the differential feed setting and increase the number if you are also getting any rippling. Experiment for the best setting.
The best thing for the really stretch fabrics I have found is to control them with wonder tape. Have you seen it? Its water soluable and you use pressure to apply it- but not the iron, or it will melt. Press the garment hem up first, then apply tape to the underside of the hem edge, remove the adhesive backing paper strip, then fold back and press into place with fingers. Then coverstitch over the area.
Some experimentation is needed on the thinner and thicker fabrics for the right tension, presser foot presser and differential feed settings, on any machine. Hope that these tips help.

I don't own the Bernina brand coverhem machine, but with the brand I own, I like to use Steam-a-Seam Lite to gently fuse the hem before I coverstitch it. If you can find it in Finland or online, I highly recommend it. I use the 1/2 inch wide version for hems. It is not stiff at all, and knits still have good stretch and retention.

I've learned with both my coverstitch and serger that going to the 'minus' differential setting as I'm going over seams helps prevents the fabric from gathering and folding.
