You must perform maintenance, calibration and repair work according to the latest versions of
Service Manuals on the support website http://www.universal-robots.com/support.

6.1 Safety Instructions
After maintenance and repair work, checks must be done to ensure the required safety level.
Checks must adhere to valid national or regional work safety regulations. The correct function-
ing of all safety functions shall also be tested.
The purpose of maintenance and repair work is to ensure that the system is kept operational
or, in the event of a fault, to return the system to an operational state. Repair work includes
troubleshooting in addition to the actual repair itself.
When working on the robot arm or control box, you must observe the procedures and warnings
below.
DANGER:
1. Do not change anything in the safety configuration of the
software (e.g. the force limit). The safety configuration is de-
scribed in the PolyScope Manual. If any safety parameter is
changed, the complete robot system shall be considered new,
meaning that the overall safety approval process, including
risk assessment, shall be updated accordingly.
2. Replace faulty components using new components with the
same article numbers or equivalent components approved by
Universal Robots for this purpose.
3. Reactivate any deactivated safety measures immediately after
the work is completed.
4. Document all repairs and save this documentation in the tech-
nical file associated with the complete robot system.
