DANGER

IF THE INSPECTION OR MAINTENANCE PROCEDURE CALLS FOR OPERATION OF THE ROBOT, STAY OUT OF THE
WORKING AREA OF THE ROBOT DURING OPERATION. KEEP WATCHING THE ROBOT MOvEMENT AND SURROUNDING
AREA SO THAT THE OPERATOR CAN PRESS THE EMERGENCY STOP BUTTON IF ANY DANGER OCCURS.

WARNING

• THE ADjUSTMENT AND MAINTENANCE WORK WITH THE COvER REMOvED NEEDS THE SPECIAL KNOWLEDGE AND
SKILL. IF UNSKILLED WORK PERSON PERFORMS SUCH WORK, THIS MAY INvOLvE RISK. THE ADjUSTMENT AND

MAINTENANCE WORK MUST BE PERFORMED ONLY BY PERSONS WHO HAvE THE REQUIRED QUALIFICATIONS

  DESCRIBED IN “2. QUALIFICATION OF OPERATORS/WORKERS” IN SECTION 4.1 OF “SAFETY INSTRUCTIONS”, WHILE
  REFERRING TO THIS MANUAL.
•  WHEN THE ROBOT DOES NOT NEED TO BE OPERATED DURING ADjUSTMENT OR MAINTENANCE, ALWAYS TURN OFF
  THE CONTROLLER AND THE ExTERNAL SWITCH BOARD.
•  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 INTERNAL PARTS OF THE CONTROLLER.
•  WHEN ONLY MAKING ELECTRICAL INSPECTIONS AND REQUIRING NO MECHANICAL MOvEMENT OF THE ROBOT,
  KEEP THE EMERGENCY STOP BUTTON PRESSED.
•  BE CAREFUL NOT TO NEGLECT TIGHTENING SCREWS OR BOLTS. IF ANY COvER IS NOT SECURED FIRMLY, THIS MAY
  CAUSE NOISE, COvER DROPPING AND FLYING, HAND ENTANGLEMENT IN DRIvE UNIT DURING TEACHING, OR

BURN DUE TO HAND IN CONTACT WITH HOT SURFACE. SO, BE SURE TO TIGHTEN ALL THE SCREWS AND BOLTS

SECURELY.
•  BE SURE TO USE THE LUBRICANT SPECIFIED BY YOUR DISTRIBUTOR.

•  DO NOT MODIFY ANY PARTS ON THE ROBOT OR CONTROLLER. MODIFICATION MAY RESULT IN UNSATISFACTORY
  SPECIFICATIONS OR THREATEN OPERATOR SAFETY.
•  WHEN ADjUSTMENT OR MAINTENANCE IS COMPLETE, RETIGHTEN THE BOLTS AND SCREWS SECURELY.
•  PLACE A SIGN INDICATING THE ROBOT IS BEING ADjURED OR INSPECTED TO KEEP OTHERS FROM OPERATING THE
  CONTROLLER POWER SWITCH, PROGRAMMING BOx, HANDY TERMINAL, OR OPERATION PANEL. WHEN NECESSARY,
  INSTALL AN APPROPRIATE SWITCH KEY LOCK MECHANISM OR ARRANGE A WATCHER.

CAUTION

•  Only qualified engineers who have the skill and license in accordance with the laws and regulations in each
  country are allowed to carry out the periodic inspection.
•  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.
