6.3 Inspection after storage for long period of time
If the vacuum pump is stored for a long period of time without operation, it may not work properly
due to occurrence of rust etc. If it has not been used for a long period of time, make a request of
your nearest service center to perform inspections.
6.4 Overhaul
The inspection items are as mentioned above. However we recommend periodical overhauls under
the condition where the pump is polluted or its performance deteriorates excessively depending on
the service conditions.
Overhauls are necessary to maintain the performance (including safety) and continue scheduled
production.
For overhauls, contact your nearest service center described at the end of this document.
Note that you are requested to complete and submit the pollution certificate attached to the end of
this document.
Carry out an overhaul once a year.
In addition, if the pump is polluted or its performance deteriorates
excessively under your service conditions, carry out an overhaul even
if it is within one year.
In an overhaul, at least the parts described in "9. Main replacement
