Check that the back of the rivet (nail) fits into the nail die. Put the rivet nail aside and place the nail die into the bottom slot of the hand press.

Snap the front of the rivet (head) into the head die. The rivet head should stay securely in the die.

To insert the head die into the press:

Use your fingers, a screwdriver, or a hex key, as needed, to unscrew the tightening mechanism on the side of the press near the top die fitting.

Insert the die upward and hold it in place.

Tighten the tightening mechanism.
