1.7 Maintenance and troubleshooting
General
The robot requires only minimum maintenance during operation. It has been
designed to make it as easy to service as possible:
• Maintenance-free AC motors are used.
• Grease is used for the gearboxes.
• The cabling is routed for longevity, and in the unlikely event of a failure, its
modular design makes it easy to change.
Maintenance
The maintenance intervals depend on the use of the robot. The required
maintenance activities also depend on the selected options. For detailed information
on maintenance procedures, see the maintenance section in
