Inspect the die sets
Inspect the die sets
Put the die set on a table.
1.
Put your hands on both ends of the die set and push the top plate straight down.
2.
Check if the die set functions smoothly. If not, the die set is worn.
When the die set seems OK, insert the die set into the die set slot.
3.
Run a number of sheets through the machine and inspect the holes.
4.
•
The holes must be clean and even. Torn or frayed edges indicate wear.
•
The holes must be punched completely. Chips that are still attached to the holes indi-
cate wear.
•
The holes must be straight, evenly spaced from the paper edge and correctly aligned.
Skewed holes indicate wear.
