the numbers facing up.
3. Pull up on the plunger knob and push the handle all
the way to the left.
4. Select the correct dies for the size desired. (Size
marked on the back end or face of the dies.)
5. Numbers on the Dies must correspond with those on
the Die Head Slots. Insert Dies to the line marked on
the Dies – numbered edge up.
6. Rotate the handle back to the right so that the plunger
knob pops back down flush against the Die Head.
7. To set or adjust for desired size loosen the screw for
the desired position block size, move the block to the
right to make it Under-Size and to the left to make it
Over- Sized. When setting blocks for new dies start
