Setting the Perf Blade
When locating the perf blade to where you would like to perf you must make sure that
you can move the lower assembly and upper assembly to the location you want to perf.
This may require moving the rubber gripper wheels or other upper and lower
assemblies. The lower assemblies all have a single set screw that once broken loose will
slide along the lower shaft. These are placed in line with each other for easier access. If
you cannot see the lower assembly set screws rotate the lower shaft until they become
accessible. The upper assemblies have one set screw on the upper shaft that when
broken loose will allow you to slide or move them to the desired location.
Make sure that you have even distribution of gripper wheels across the width of your
sheet when setting your perf up. While your sheet size may not require all 4 gripper
wheels to securely guide the sheet you will want as even distribution and uniform
pressure on all the gripper wheels.
With the corresponding T-Handle wrench provided with your machine, lower the perf
blade down until the blade just touches the hardened steel lower. Then turn the T-
Handle ½ turn and hand screw the lock down to lock the blade into the down position.
You are now ready to perf. Remember, depending on the thickness of stock you may
need to adjust the perf blade up or down to fine tune your perforation.
Important: When you lower a perf or score assembly you are putting
downward force on the lower shaft. These are self tightening and
should automatically adjust. However, if you have multiple perf
assemblies operating at the same time you may need to make fine tune
adjustments to ensure matching perf depth.
