Precautions for Maintenance

Before performing inspections or part replacements, please read this "Precautions for Maintenance" section carefully and make sure you understand safe procedures.

Robot system maintenance should be performed by people who have received maintenance training provided by Epson and the suppliers.

WARNING

  • Do not disassemble the product in areas not described in the service manual or perform maintenance in a manner different from these procedures. Improper disassembly or maintenance may not only lead to a malfunction in the robot system, but can also cause serious safety issues.
  • Persons who have not undergone training must never approach a Manipulator that is turned on. Also, do not enter the work envelope. If the Manipulator is turned on, it may make unexpected movements even if it appears to be stopped, which may result in serious safety problems. Also, safe work procedures should be established and followed to prevent hazards due to unexpected movement of the Manipulator or operator mishandling of the Manipulator.
  • When checking the Manipulator's operation after replacing parts, be sure to step outside of the safety barriers. A Manipulator that has not been tested may move unexpectedly, which may cause serious safety problems.
  • Before beginning full operation, make sure that the emergency stop switch and interlocked guard switch operate. Operation without the switches functioning properly may result in the safety functions failing to operate during an emergency, which is extremely hazardous and may result in serious injury and/or severe damage to the robot system.
  • When touching the exterior terminals or connection connectors of the Controller for Controller inspection or the like, turn off the Controller and shut off the power supply to prevent electric shock.
  • Shut off the supply power before performing cleaning or retightening terminal screws. Failure to shut off the supply power may cause electric shock, product damage, and malfunctions.

WARNING

  • Remove the power plug before maintenance.

    If necessary, perform lockout for safety. For details, refer to the following manual.

    "Controller Manual"

  • Before performing any replacement work, be sure to display that work is in progress, turn off the power for the robot system and related equipment, and disconnect the power plug. Performing any work procedure with the power turned on is extremely dangerous and may result in electric shock and/or malfunction of the robot system.

  • Do not connect or disconnect the motor connector while the power is turned on. There is a risk the Manipulator may malfunction, which is extremely hazardous. Also, performing any work procedure with the power turned on may result in electric shock and/or malfunction of the robot system.

  • Use cables with securely protected high-voltage sections and connect them securely. Also, do not put heavy objects on the cables, bend them severely, pull them forcibly, or pinch them. Damaged cables, broken wires, or contact failure is extremely hazardous and may result in electric shock and/or malfunction of the robot system.

CAUTION

  • When using alcohol, liquid gaskets, or adhesives, carefully read the precautions for those products and thoroughly ensure safety. Also, pay attention to the following points. Failure to be cautious may result in fire or safety problems.
    • Do not handle near fire.
    • Use with good ventilation.
    • Wear protective equipment (such as goggles, oil-resistant gloves, and a mask).
    • If it adheres to the skin, rinse with water and soap.
    • If it enters the eyes or mouth, rinse thoroughly with clean water and seek medical attention.
  • When applying grease, wear protective equipment (such as goggles, oil-resistant gloves, and a mask) and ensure safety when performing work. If grease enters the eyes or mouth or adheres to the skin, take the following measures:
    • If it enters the eyes
      After rinsing the eyes thoroughly with clean water, seek medical attention.
    • If it enters the mouth
      If swallowed, do not force vomiting, and seek medical attention. If the mouth is contaminated, rinse thoroughly with water.
    • If adhered to skin
      Rinse with water and soap.
  • Immediately after operation is stopped, the Manipulator may be hot due to heat generated by the motor. Do not touch the Manipulator until the temperature has dropped. Operations such as teaching and maintenance should be performed only after the Manipulator temperature has dropped and it does not feel hot to the touch.
  • During maintenance work on the Manipulator, ensure about 50 cm of free space around the Manipulator.
  • When cleaning the Manipulator, do not rub it strongly with alcohol or benzene. Coated surfaces may lose their luster.
