■About component aging degradation trouble
Some components installed in our machine suffer from aging degradation during long term use.
We call such components limited-life components.
Some of the limited-life components, if used past their estimated useful life, could lead to failure
that involves smoke, offensive odors or risks at work.
For your continued safety, please replace those components during a recommended replacement
period.
■Component failure occurrence
Depending on the occurrence time, a
component failure has three general
periods (stages) - early failure, chance
failure, and wear-out failure.
・Early failure:
Failure that occurs due to a
manufacturing or other defect during
initial operations.
・Chance failure:
Sudden and unpredictable failure that
occurs during the useful life of a
component.
・Wear-out failure:
Failure that occurs as a result of aging
degradation. The number of such
failures sharply increases near the end
of the useful life of components.

■Replacement of component
For limited-life component items and a guide for the recommended replacement period, refer to the
list in this chapter.
To use the machine longer
Components or units used in the machine have limited life-spans. To use the machine over a long period of
time, replace the affected components or units before the end of their life. Please contact us for replacement.
●In NPM-TT2, parts and units corresponding to “Replacement of service life-limited component (7 years)”
and “Replacement of service lift-limited component (15 years)” are not installed.
* Component life is influenced by the usage status or environment.
The recommended replacement period stated in the list is used only as a guide. It is not meant to
guarantee the length of the component’s life.
