Manual Brake Release
As long as no power is being supplied to the robot actuators, the
brakes will be engaged automatically. However, in some emergency
situations it may be necessary to move the robot joints without
power. This can be achieved using the manual brake release tool.
NOTE: A manual brake release can only be performed on axes 2, 3
and 5.
To move the joints without power:
1. Disconnect all source of power from the robot. In some cases
it may be appropriate to unscrew the base from its work
surface and lay the robot down in a horizontal position.
2. Identify which joint needs to be moved, and push the brake
release tool through the pin hole on the joint to disengage the
appropriate brakes.
3. Keep the robot supported as you adjust the joint to a suitable
position. Be mindful of the weight of the higher joints.

Personnel should be trained on responding to abnormal situations,
including being able to locate and identify the brake release tool and
the brake release pin hole, as well as understanding the necessity of
supporting the higher joints when brakes are released.
