4.1.1  Movement Without Drive Power 
 
In the unlikely event of an emergency, when the robot power is either impossible or unwanted, you 
can use forced back-driving or contact your Universal Robots distributor if this is not possible. 
To perform forced back-driving you must push, or pull, the Robot Arm hard to move the joint. Each 
joint brake has a friction clutch that enables movement during high forced torque. 
NOTICE 
•  Moving the Robot Arm manually is intended for urgent emergency and service 
purposes only. 
•  The brake inside each joint is not designed for manual release. Attempting to 
do so without proper training may cause damage to the brake and other joint 
components. This will make the joint un-usable. 
•  Do not move the joint more than necessary.  
Not more than 160 degrees to ensure the robot can find its original physical 
position.
