■About part aging degradation trouble
Some parts installed in our machine suffer from aging degradation during long term use.
We call such parts limited-life parts.
Some of the limited-life parts, 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 parts during a recommended
replacement period.
■Part failure occurrence
Depending on the occurrence time, a
part 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
part.
・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 parts.

■Replacement of part
To use the machine longer
Parts or units used in the machine have limited life-spans. To use the machine over a long period of time,
replace the affected parts or units before the end of their life. Please contact us for replacement.
Over-
view
For limited-life part items and a guide for the recommended replacement period, refer to the list in
this chapter.
* Part 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 part’s life.
●In NPM-W2, 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.
