• Never attempt to perform inspection, adjustment, repair, or part replacement work of the robot and controller
other than those described in this manual. Such work requires special knowledge and may involve risk.
• Before starting each adjustment work, thoroughly read this Chapter to fully understand its contents.
• If a safety enclosure has not yet been provided right after installation of the robot, rope off or chain off the
movement area around the manipulator in place of a safety enclosure, 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 the operator or other personnel from entering the movement area of
the manipulator.
• To check the operation after the adjustment has been made, see "4.6.1 Trial operation" in the Safety
Instructions.
• Be sure to wear safety gloves before starting the work. If you touch any steel material part with bare hands, this
may cause rust.
• Be careful not to drop any screw or bolt during cover removal work.
• For details about cautions on controller, see the User's Manual for controller.
