* The belt tensile jig is an assembly jig. Use the jig when adjusting belt tension.
The brake is mounted on each joint to prevent the arm from lowering due to its own weight while the
Controller power is OFF or the motor is OFF status. The brake does not work during replacement. Be
careful when performing maintenance work.
When removing the Joint #2 motor, tilt the Arm #2 and press it against the Arm #1.

When pressing the arm, put a piece of cloth or a similar material between the arms to avoid contacting each other.
This protects the arm surfaces from scratching and paint peeling off.
