• Assemble the heads with the desired male scoring discs, female collars, and spacers. Position and lock both lower scoring heads onto the lower scoring shafts.
• Position the heads on the upper scoring shafts with the male scoring discs centered over the female grooves. Lower and lock the upper shafts. Rotate the shafts two full turns to align the heads, then lock the upper heads to the shafts.
• Run a sheet through and adjust the upper scoring shafts until the desired scoring depth is reached.
• No need to remove the heads to change the male scoring discs or the hinge width. Simply loosen the nuts with the tools supplied and slide along the shaft. Twist and remove the male discs and thin spacers, then replace and re-assemble the heads.
• The red male disc in the wide female groove produces a wider score for heavier cover stocks. Use the red male in the narrow female groove for medium covers.
• The black male scoring disc in the narrow female groove produces a narrower score, perfect for light cover stock.
• Red and black male scoring discs can be combined on the same set up, typically red for the spine score and black for the hinge.
• The hinge width is adjustable from 4.0mm (0.157”) to 7.0mm(0.276”)score using the thin spacers provided.
