⚫ Do not remove any parts that are not covered in this manual. Follow the maintenance procedure strictly as described in
this manual. Do not proceed using any methods other than described in this manual when you do replace a part or
maintain the equipment. Improper removal of parts or improper maintenance may not only cause improper function of
the robot system but also serious safety problems.
⚫ Keep away from the Manipulator while the power is ON if you have not taken the training courses. 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 when it seems to be stopped.
⚫ 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.
⚫ 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.
⚫ To shut off power to the robot system, disconnect the power plug from the power source. Be sure to connect the AC
power cable to a power receptacle. DO NOT connect it directly to a factory power source.
⚫ Before performing any replacement procedure, turn OFF the Controller and related equipment, and then disconnect the
power plug from the power source. Performing any replacement procedure with the power ON is extremely hazardous
and may result in electric shock and/or malfunction of the robot system.
⚫ When maintaining the manipulator, wear at least the following protective gear. Working without protective gear may
cause serious safety problems.
