9.1 Inspection Schedule
Conduct daily and periodic inspections to ensure the long life of the robot and its performance.
Proper inspections are essential not only to assure that the mechanism will be able to function for a
long period, but also to prevent malfunctions and assure safe operation.
Inspection intervals are given in the levels shown in Table 9-1 "Inspection Schedule".
In Table 9-1 "Inspection Schedule", the inspection items are classified into three types of operation:
operations which can be performed by personnel authorized of the user, operations which can be
performed by personnel being trained, and operations which can be performed by service company
personnel.
Only specified personnel are to do inspection work.
