* The belt tensile jig and J1 brake positioning jig are assembly jigs. Use these jigs in relevant maintenance
steps.
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.
