Functioning

Press the Car-Brake button to release the car. Then press the forward button to lift the car.
When the car reaches the top of the tower and begins to fall, press the brake button to stop the car
in the vertical position, also brake the seat. Press the forward button and the car-brake button to deactivate their function
so the car can fall freely. Before arriving the lower rail press the seat break and press the forward button.
