Cautions on Maintenance and Inspection

When performing inspection or maintenance of the robot, strictly observe the following
precautions to protect yourself and coworkers.
• Be sure to remove the power plug of the controller from the power source before approaching
the robot for maintenance and inspection.
• When moving the robot by hand while the power is connected, be sure to assure the safe
work and effect an emergency stop beforehand.
• In the above situation, if the work is to be done while the axis 3 motor brake release switch is
pressed, be sure to perform the work by two (2) persons.
One person should carry out the work while the other is monitoring the work outside the
hazardous zone. The latter person should watch the work and be ready to turn off the
controller switch if any abnormality occurs. Once the controller power is turned off, the
motor brake actuates even if the axis 3 motor brake release switch is kept pressed.
• If the axis 3 motor brake release switch is pressed while the robot is carrying a heavy
workpiece, Axis 3 may drop suddenly. To avoid this, the customer should take all necessary
measures by themselves.
