¶ How to secure the ring in place

- When engraving the inside
Insert the ring in between the finger chucks. Rotate the rotary clamp to inward-outward directions to lock and secure the ring in place. Make sure that the ring is firmly attached and locked so it won’t fall off or spin during operation.
If the thickness of ring is not even, mix different sized chuck fingers to hold it.

¶ How to replace finger chucks
Choose the appropriate finger chucks for your ring. Insert the finger chucks into the holes then fasten them tightly with the use of a finger chuck spanner.
