2.4 MAINTENANCE AND INSPECTION OF MAJOR PARTS

Periodical inspection and maintenance are requisite to maintain
the initial performance and reliability of the product. Table 2-4-1
(Maintenance & Inspection List) has been compiled assuming
standard operating conditions, and the specifications in the ta-
ble are greatly variable depending on the actual operating envi-
ronment and conditions. Remember that, if the maintenance
and inspection are not enforced properly, the operating hours of

Layout of Major Parts

the product will not only reduce considerably but other
unfavorable influences may produce.
Rubber parts may deform or degrade after long period of stor-
age even if they are not used in this period.
The service life of the drum is variable depending on the tape
used and operating environment.
