GBC Auto 50 MBM Crease - Manual (Page 8)

Changing Crease Matrix
Matrix
Bar
The machine is supplied with two crease matrix bars that have different widths of slot on
either side. One of these slots allows the operator to use replaceable self adhesive matrix
bars, the other three may be changed depending on the thickness of the material to be
creased.
The bar must only be changed while the machine is in its rest position with the knife at its
highest point. Withdraw the bar from the slot, turn or replace with the correct size slot,
and slid the bar into the machine until it stops.
