4.2.2 Maintenance schedule
Scheduled and non-predictable maintenance
The robot must be maintained regularly to ensure proper function. The maintenance
activities and 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!
Life of each component
The inspection intervals
do not
specify the life of each component. Values for these
are specified in the section

"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
Operating hours counted by the DTC = Duty time counter.
iii
Axis-1 and axis-4 timing belts can be accessed and inspected only after the axis-1 and axis-4
motors are removed. It is recommended to inspect the timing belts when replacing the motors.
