I checked the owner's manual the other day and I could not find any mention of twin needle stitching for this model, so I did an experiment. I used my number 37 presser foot, made sure the needle plate had a wide enough opening for both needles, inserted my twin needle, and threaded two threads through the machine and it worked. I will make a notation in my owner's manual. I may not use it a lot but at least I know I can.

Check the width of your stitch. Most machines have a twin needle button that limits the width to around 4mm. That avoids breaking needles since you can do twin needle embroidery with built in stitches.
If your standard stitch width is 6mm, 4mm would avoid a too wide swing of the needles.

You would buy the needles by use. Pintucks usually use smaller width needles.

You can twin needle pintuck on an old manual machine if you can find the foot. (Generic by shank)
Those machines would have to limit width of zigzag also.

I tried it once on my 1530 but I didn't like the stitch. Surprised that it wasn't in the manual.

I'm just doing straight stitch twin needle sewing.
