If you have a low shank machine but no snap-on feet you need a low shank snap-on adapter (you can buy this separately from our shop and it is also included in our ultimate presser foot set 32 pcs (bonus adapter, in the slot marked with a star). 

Step 1: attach the low shank snap-on adapter (bonus) adapter (B) to your machine’s shank (A) with the holding screw (C). 

Step 2-3: place the presser foot under the bonus adapter, lower the presser foot lever so the presser foot bar (F) snaps into the opening in the bonus adapter (E) 

Step 4: push the red button (D) at the back of the bonus adapter to release the presser foot from the adapter

Attach the adapter to your machine just like you attach a Bernina presser foot.  This gives your Bernina machine a low shank. You can now use all low shank accessories. To use a snap-on presser foot you will have to attach a low shank snap-on adapter as soon in steps 3-5.

Step 1-2: attach the adapter (A) to your machine, just like you attach a normal presser foot. Note: This makes your Bernina machine, a low shank machine. Now you can use the adjustable zipper foot, the gathering foot and the two different darning feet. 

Step 3-5: To use the other feet you attach the bonus adapter to the Bernina adapter as pictured and explained in detail at the Bonus Adapter section above.
