ADJUSTING THE RAC ROLLERS
The RAC rollers are set from the factory and it is NOT recommended to make any
adjustments to this without consulting with MBM’s tech-support department.
Should an adjustment be necessary, please follow the steps below.
Loosen the small bearing block lock screws. This allows very slight adjustments of the
bearing block to be made by loosening the thumb lock and turning the height
adjustment screw in the middle of the bearing block. This is a very fine thread and is
capable of making very slight adjustments. Turning the adjustment screw clockwise will
increase the bar pressure, as counterclockwise will decrease the pressure. Once the
adjustment to the bar has been made, slightly tighten the thumb lock and re set the
block set-screws.
ADJUSTING RAC TOP DEAD CENTER
The top dead center of the RAC will need to be adjusted from time to time. To do this
turn the machine off, remove the operator side cover, and manually rotate the eccentric
shaft to the top dead center. Then locate the adjusting shaft collar on the end of the
eccentric on the operators side and take a 5/32 allen wrench and loosen the button
head screw and rotate it to the 6 o’clock position. This will ensure proper alignment of
the crease bar.
CHANGING THE LOWER CREASE DIE
The Lower crease die can easily be changed to accommodate thicker stocks by removing
the non-operator side cover, slide the bar out and flip it over to use the wider die
channel. Please note, custom die’s are available upon request.
