1.3 Die Set Service
The Die Set assembly is not serviceable other than inspection and periodic lubrication.
If a Die Set is at its end of life, it will tend to cause misfeeds due to hanging chips. This
is a result of die plate wear, and not pin wear, which cannot be corrected. When this
occurs, the Die Set should be replaced with a new one.
1.3.1 Die Set Life Expectancy
The StreamPunch Pro standard Die Sets have a minimum life expectancy of 500K
cycles (sheets of paper punched). Heavy Duty die sets have a minimum life
expectancy of 4M cycles (sheets of paper punched). With periodic lubrication and
optimum paper types, life may exceed this number. Variables that affect life
expectancy:
•
Failure to follow the lubrication schedule or using the incorrect lubricant
•
Variety and types of paper being punched
•
Cover stocks being punched
•
Other environmental conditions
