How to use
Position A4 sheets in the comb binder punch unit and create the required hole pattern for 21-ring A4 combs. Align the punched stack with the comb spine and open the comb on the binding machine. Insert the comb rings through the punched holes across the document, then close the comb to secure the pages.

Follow the instructions specific to your manual or electric comb binding machine for safe operation.
