Remove the two screws holding the Die rail at the front of the StreamPunch.
Step 3:
Remove the four screws holding the Die rail at the rear of the StreamPunch.
Step 4:
Remove the wire that attaches the solenoid to the PC board. After all the screws and
Step 5:
the wire are removed you can now remove the back gage and rail as an assembly.
Facing the back gauge pull the rail from the right side first and slide out the assembly.
Step 6:
Install the new back gage. Also, when replacing the two screws that hold the die rail
Step 7:
make sure you install the brush that is provided in the kit.

correctly with the notch. The new E-Prom not only provides software to work with the
new Back Gage mechanism, it also contains new software that changes the default time
to 4 minutes. This provides the customer sufficient time to clear a jam without returning
to by-pass mode.

Skew Adjustment: Check for proper hole alignment to paper edge.
Step 13:
The back gage is designed to give you some adjustment when the three screws are loosened.
It will give you up and down play, which allows you to remove skew.
The ideal situation is to have the back gage all the way to the top position.
If not, paper can slip past the paper stops and give you a deep punch. This may occur if the back
gage is tightened into place in it's bottom most position. This situation is most likely to occur when
using the VeloBind or PB die sets, which are at one end of the Back Gage tolerance spectrum.
Three-Hole Die Set: At the other end of the Back Gage tolerance is the Three-Hole Die Set. If the
customer owns a Three-Hole Die, check this die to see if it is easy to insert and remove. If the die is
too tight you will need to lower the back gage slightly to achieve the tightness you desire, while still
retaining the PB and VeloBind functionality mentioned above.
