4.8 Back Gauge Assembly

4-36
The Back Gauge assembly pauses the paper just as the edge has entered the die
set. Working properly, the sheet will pause only long enough for the holes to be
punched correctly. The Back Gauge assembly also controls the paper chad falling
into the chad bin, significantly reducing the amount of chad that could flow through
the paper path. Some chad falls outside the chad bin and should be cleaned up
with a vacuum cleaner during each servicing.
Warning: Disconnect the Advanced Punch from its power source before
removing the Back Gauge assembly. Failure to observe this warning can result in
severe injury or death and damage the punch.
