General
The robot, consisting of robot and controller cabinet, must be maintained regularly
to ensure its function. The maintenance activities and their respective intervals are
specified in the table below.
Non-predictable situations also give rise to inspections of the robot. Any damages
must be attended to immediately!
The inspection intervals do not specify the life of each component.

"Regularly" implies that the activity is to be performed regularly, but the actual interval may not be
specified by the robot manufacturer. The interval depends on the operation cycle of the robot, its
working environment and movement pattern. Generally, the more contaminated environment, the
shorter intervals. The more demanding movement pattern (sharper bending cable harness), the
shorter intervals.
ii
Service inspection including dismounting of robot parts shall always be done outside the clean
room area.
