Precautions for Maintenance

Read this chapter carefully to understand safe maintenance procedures before
performing any maintenance.
Only personnel who has taken maintenance training held by us and suppliers should
be allowed to perform the maintenance of robot system.
■ Do not remove any parts unless otherwise instructed by maintenance
manual. Follow the maintenance procedure strictly as described.
Improper removal of parts or improper maintenance may cause not
only malfunction of the robot system but serious safety problems.
■ If you have not received training, keep away from the Manipulator while
the power is ON. Do not enter the operating area while the power is
ON. Entering the operating area with the power ON is extremely
hazardous and may cause serious safety problems as the Manipulator
may move even it seems to be stopped. In addition, establish a safe
working procedure to prevent danger due to unexpected movement of
the Manipulator or wrong operation by the operator, and work
according to the procedure.
■ When you check the operation of the Manipulator after replacing parts,
be sure to check it while you are outside of the safeguarded area.
Checking the operation of the Manipulator while you are inside of the
safeguarded area may cause serious safety problems as the
Manipulator may move unexpectedly.
WARNING
■ Before operating the robot system, make sure that both the Emergency
Stop switches and safeguard switch function properly. Operating the
robot system when the switches do not function properly is extremely
hazardous and may result
in serious bodily injury and/or serious damage to the robot system as
the switches cannot fulfill their intended functions in an emergency.
■ When touching the terminal on the outside of the controller or
connector for maintenance, turn OFF the Controller and shut off power
supply to prevent electric shock.
■ Be sure to shut off the power supply before cleaning or tightening the
terminal screws. Failure to shut off all phases may result in electric
shock, product damage, or malfunction.
