Using this model is straightforward. Just connect it to your analog DC power source, and it'll start running. When you're done using it, make sure to turn off the power to save the motor. As for maintenance, keep an eye on the wheels. Since the wheel wear is minimal, you won't have to worry too much, but a gentle cleaning every once in a while can keep it running smoothly. You can use a soft cloth to wipe the body and remove any dust. If you want to add sound, you can install a speaker in the factory - drilled tender. When handling it, be careful as it's a fragile brass model. Always store it in the original box and foam to protect it from damage. If you have any issues with your purchase, reach out to us within 30 days, and we'll work to make it right. Just remember, if you're returning it, you'll be responsible for the return shipping unless the item arrived damaged.
