Using this model is straightforward. Just connect it to your DC - analog power source and it should start running well. Remember, it has a moderate motor/gearbox noise, so don't be alarmed if you hear a bit of sound. When handling the model, be gentle as it's a fragile item, especially since it's made of brass. For maintenance, keep it in a dry place when not in use. You can use a soft cloth to dust it occasionally. Since there are no spare parts included, try to handle it carefully to avoid any damage. If you're shipping it back for a return, make sure to pack it well as it was originally packed to avoid any further damage.
