* The belt tensile jig is an assembly jig. Use this 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.
