7 Maintenance and repair

7.1 Maintenance and repair
General
Corrective maintenance must only be carried out by personnel trained on the robot.
Maintenance or repair must be done with all electrical, pneumatic, and hydraulic
power switched off, that is, no remaining hazards.
Hazards due to stored mechanical energy in the manipulator for the purpose of
counterbalancing axes must be considered before maintenance or repair.
Never use the robot as a ladder, which means, do not climb on the controller,
manipulator, including motors, or other parts. There are hazards of slipping and
falling. The robot might be damaged.
Make sure that there are no loose screws, turnings, or other unexpected parts
remaining after work on the robot has been performed.
When the work is completed, verify that the safety functions are working as
intended.
Gearbox lubricants (oil or grease)
When handling oil, grease, or other chemical substances the safety information of
the respective manufacturer must be observed.
Warning
Hot oil or grease
