The brake is mounted on the Joint #2 to prevent the arm from lowering due to its own weight while the Controller
power is OFF or the motor is OFF status. However, the brake does not work during replacement.
To replace the Joint #2 motor, tilt the Arm #2 and press it toward the Arm #1. (See the step (3)
When pressing the arm, put a cloth or a similar material between the arms to avoid each arm from contacting.
This also protects the arm surfaces and coatings.
