When replacing the die, first stop the punch slider at the next dead center. Then loosen the screw fixing the handle and lift the slider. Remove the removed mold, then lower the punch slider to the bottom dead center, and then measure the height of the mold with the new mold installed.
Then adjust the distance between the punch slider and the punch table to the same size. Then lift the slider and put in a new mold. Then slowly put down the slider. Insert the template into the mounting hole of the slider and press it into the mold.
