What must you do before removing the J3-axis motor?

• A. Disconnect the power supply
• B. Support the J3-axis arm
• C. Calibrate the position
• D. Loosen all screws

Answer: (B)

Before removing the J3-axis motor, it is essential to support the J3-axis arm. This action ensures that the arm remains stable and does not fall or become unbalanced during the removal process. Supporting the arm prevents potential damage to both the arm and the motor, as well as reducing the risk of injury to personnel working on the machine. By securing the arm, you maintain control over its position, which is crucial when any components are detached or moved. While disconnecting the power supply is a critical safety measure generally performed in such procedures, it does not specifically address the stability of the J3-axis arm during motor removal. Calibrating the position and loosening screws may be necessary steps in certain scenarios, but they are not as immediately vital as ensuring the arm's support for safe motor removal.
