6.4. Motor Replacement
Warning:
When motor is separated, the ARM will drop due to its built-in brakes inside the motor for holding robot's posture. Take necessary precautions such as fixing A2 FRAME with 2nd ARM by using M20×250 bolts or lifting and hanging the ARM by using crane as shown in the Figure in order to prevent such dropping. Do not hold the ARM in your hand.
In case of contacting the motor right after it stops, ensure the motor temperature. Motor weights are listed as follows. Be careful when dealing with the motor.

Warning:
In this work, there is a part performed with the motor [ON]. Therefore, perform the work in pairs. An observer must always be ready to activate an emergency stop. The other perform the work quickly and carefully. An escape route should be determined before starting work.
After replacing axis H or V, ensure that M20 bolt for supporting ARM has been removed before operating the robot.
