Do you mean the Bernina Activa 145? If so, you can press and hold the Reverse button. The button is to the right of the needle bar; it's to the left and below the needle stop Up/Down button. The button is indicated with a raised U with an arrow at the top of the right side of the U. Note: this "quick reverse" will only work if the stitch length is <= 3mm. If you want to sew in reverse without holding the Reverse button, quickly press the button twice. Press the Reverse button once more to sew forward.

This is explained in the manual for the Bernina Activa 145. The manual is available on the support page: https://www.bernina.com/en-US/Machines-US/Series-Overview/BERNINA-activa/BERNINA-activa-145 . The current link to the manual is https://www.bernina.com/BERNINA/media/Support/Sewing_Quilting_Embroidery/activa/activa_145/Documents/EN/activa-135-145-EN.pdf .

I hope this helps.

Look it up in your manual or go to Bernina website and you can type the request in. They will help. :-)

Yes, you can purchase a replacement needle threader for the Bernina 1130. Here's one source: https://www.sewingpartsonline.com/needle-threader-bernina-0016575201.aspx . Other sites have the piece for sale.

I hope this helps.

As far as I know, the Patchwork 140 doesn't have a needle stop up/down button. You'll need to use the hand wheel to bring the needle up or down, as needed. The Bernina machines that have a needle stop up/down button have this button below the LCD screen. (On those machines, it's usually the left-most button below the LCD.) I suspect the index giving a page number for the Needle Stop Up/Down button is a artifact of using the same index for multiple machines.

The manual for the Patchwork 140 is available at Manuals Lib here: https://www.manualslib.com/manual/1002243/Bernina-Activa-131.html . The Bernina 135 has the needle stop up/down button. See https://www.bernina.com/en-US/Support-US/Machines/BERNINA-activa/BERNINA-activa-135 . The manual for this model is https://www.bernina.com/getdoc/90f75840-2b12-4f46-88f2-76f09e35d8d4/030529-52-04_0303_a135-a145_EN .

I hope this helps.

You can probably remove it from your machine. It won't matter since you don't use it anyway.

Install a brand new needle. Verify that it is installed correctly and is facing straight forward. If it is still not threading properly, then something may be bent or out of place in the threader.

I would contact Bernina's Support:

Please be advised that the newer machines (Classic models) such as the 130-180 and up, have a totally different geometry. This is to say that the older machines have a shorter distance from the center of the presser bar to the needle center. The newer machine design was increased to provide space for needle threaders etc. Older machines will use an older Walking foot model (still available).

you'll have to check with a bernina dealer for the part
