Before beginning work
Periodic inspection and maintenance are essential to ensure safe and efficient operation of
YAMAHA robots. This chapter describes periodic inspection items and procedures for the
PHASER series. Before beginning work, read the precautions below and also in Chapter 1
"Safety Instructions" and follow the instructions.
[Safety precautions]
(1) Read and understand the contents of this chapter completely before attempting to
adjust the robot.
(2) Place a sign indicating that the robot is being adjusted or serviced in order to keep any
other person from operating the controller power switch, programming box or Handy
Terminal, and the operation panel, etc.
(3) If a safety enclosure or fence has not yet been provided right after installation of the
robot, rope off or chain off the movement area around the robot in place of a safety
enclosure or fence, and observe the following points.
1. Use stable posts which will not fall over easily.
2. The rope or chain should be easily visible by everyone around the robot.
3. Place a conspicuous sign prohibiting anyone other than the person who is adjusting
the robot from entering the movement area of the robot.
(4) To check operation after adjustment, refer to "Safety Instructions" in Chapter 1.
(5) For precautions on handling the controller, refer to the controller user's manual.

DANGER
If the inspection or maintenance procedure calls for operation of the robot,
stay out of the working area of the robot during operation. Do not touch any
parts inside the controller.
Keep watching the robot movement and surrounding area so that the
operator can press the emergency stop button if any danger occurs.
