Maintaining the robot

This function supports maintenance and inspection so that the robot can be used for a long time without
trouble.
Efficient maintenance is supported though notification of the time of maintenance parts replacement or
overhaul based on the actual operating status of the robot. However, in order to prevent failure
beforehand and ensure prolonged service life and safety of the robot, we strongly recommend periodic
maintenance and inspection be carried out.
This chapter explains maintenance and inspection of parts that are subject to this function.
For details on robot inspection items, implementation time of periodic inspection, calculation of operating
time, and maintenance and inspection procedures, refer to "5. Maintenance and Inspection" in the
separate volume "Instruction Manual/Robot Arm Setup & Maintenance".
