2 Precautions

CHAPTER 5 Periodic Inspection

2 Precautions

(1)Periodic inspection must be performed by or in the presence of personnel who have received the Robot Training given by YAMAHA or YAMAHA dealers.

(2)Do not attempt any inspection, adjustment, repair and parts replacement not described in this manual. This work requires specialized technical knowl- edge and skill, and may also involve work hazards.

(3)When inspection is required inside the safeguard enclosure, always turn off the controller and also the external switch board.

(4)If the inspection or maintenance procedure calls for operation of the robot, stay outside the safeguard enclosure.

(5)Place a sign indicating the robot is being inspected, to keep others from oper- ating the controller switch, programming unit or operation panel.

(6)Use only the lubricants specified by YAMAHA or YAMAHA dealers.

(7)To check the operation after inspection, refer to "6 Trial operation" in Chapter 1.

WARNING

•When you need to touch the terminals or connectors on the outside of the controller during inspection, always first turn off the controller power switch and also the power source in order to prevent possible electrical shock.

•Never touch any internal parts of the controller.

For precautions on handling the controller, refer to the "YAMAHA robot control- ler owner's manual".
