When reversing the jaws, you will put them in using reverse ordering. So the #4 jaw goes into the #1 slot (so first), #3 jaw goes in the #2 slot, #2 jaw goes in the #3 slot, and #1 goes in the #4 slot.
The way to tell aside from the stamped numbers on the jaws is by the distance of the scroll teeth on the jaw from the edge of the jaw that is going in first.
The first jaw to go in will have the first tooth closest to the face going into the scroll. So in your picture of all 4 jaws facing the scroll teeth up, when putting them into the chuck with the beveled face inwards, the one on the right end will go in first, followed by each jaw in sequence.
If you are reversing the jaws then it will go in the opposite order, starting with the one on the left end.
I hope that helps.

Hi All
I was very lucky as my wife treated me to a Soba 4 jaw central reversible chuck to get on with my work as I was having so much trouble filing the jaws of the HBM 50m 4 jaw chuck.
The Soba is a really good chuck but the only issue I have is its not clear how to reverse the jaws correctly. Each jaw is marked with a number on one side (see one marked as 1 on one side) and are marked again on the other (the one marked as 1 has 4 on the other side). How do I get these correctly aligned up when adding them in reverse etc? It may be obvious but I can't really get on top of it?
?
Many thanks
Rob
