Using this model is straightforward. Just connect it to an analog DC power source and watch it run. Since it's an older model, handle it gently to avoid any damage. When not in use, store it in the original box to protect it from dust and scratches. For maintenance, keep an eye on the wheels and clean them regularly to ensure smooth operation. If you notice any excessive noise, it might be a good idea to check the motor and gearbox.
