7 Maintenance
7.1 Introduction
Please read the "Maintenance Safety" section, this manual, and other related documents
carefully before maintenance. Perform the maintenance after you have gained a full
understanding of the safe maintenance methods.
7.2 Maintenance safety
Warning
 Strictly follow the maintenance procedures. Do not disassemble any part of the
robot.
 The maintenance should only be performed by designated professionals.
 If you have not been trained, stay away from the robot when it is powered on.
Also, do not enter the robot's range of motion. Even if a powered-on robot seems
to stop, it may move accidentally and cause serious safety problems.
 Be sure to confirm the action of the robot after replacing the parts outside the
safety fence. Otherwise, the robot may perform unexpected actions and cause
serious safety problems.

Before entering normal operation, make sure that the emergency stop switch and
the safety fence switch are operating normally. If the robot works in a state where
the switches are not operating normally, the safety functions cannot be
guaranteed in the event of an emergency, and serious injury or damage may
occur, which is extremely dangerous.
7.3 Maintenance outline
7.3.1 Battery replacement
7.3.1.1 Safety risks with batteries
Under normal conditions of use, the electrode materials and liquid electrolytes in the
batteries will not be exposed to the outside provided that the battery integrity is
maintained. Risk of exposure only occurs in the case of abuse (mechanical, thermal,
electrical), which may lead to the activation of safety valves and/or the rupture of the
battery containers. Electrolyte leakage, electrode materials reaction with moisture/water
or battery vent/explosion/fire may follow, depending upon the circumstances.
Warning
 Pay particular attention to the use of batteries. Avoid the improper use described
below to prevent potential heating, liquid leakage, explosion, and fire.
 Improper use includes: attempting to charge, deformation under compression,
disassembling, short circuit, improper battery connection, heating, placing in fire,
