1.2 Releasing a person trapped by the robot axes
Overview
Make sure that any attempt to release a person trapped by the robot axes does
not further increase the risk of injury.
Releasing the robot holding brakes will make it possible to move the robot manually,
but only small robots are light enough to be moved by human force. Moving larger
robots may require using an overhead crane or similar. Make sure that the right
equipment is available before releasing the brakes.

WARNING
Before releasing the brakes, make sure that the weight of the arms does not
increase the pressure on the trapped person, further increasing any injury.
Action
Press any of the emergency stop buttons.
DANGER
When releasing the holding brakes, the
robot axes may move very quickly and
sometimes in unexpected ways.
Make sure that the weight of the arm does
not increase the pressure on the trapped
person, further increasing any injury.
Locate the brake release unit.
Release the holding brake on a particular
robot axis by pressing and holding the
corresponding button on the internal brake
release panel.
The brake will function again as soon as
the button is released.
Move the robot so that the trapped person
is released.
Help the trapped person and make sure
he/she gets medical attention.
Make sure the robot cell is cleared so that
no one else runs the risks of being injured.
