■
By removing the bolts, the Arm #1, #2, #3, #4, #5, and #6(end effector) can be
separated. There is a possibility of hands and fingers being caught and/or
damage or malfunction to the Manipulator. Be very careful when removing the

the other worker is removing the bolts.
■ The Arms are connected by the internal cables. When replacing the parts, place
