Using this model is easy. Just connect it to your analog DC power source and it should start running. Make sure to handle it gently because it's a delicate brass model. When you're not using it, store it in the original box and foam to protect it from scratches and damage. Keep an eye on the wheel wear, but since it has minimal wear now, it should last a while. If you hear any unusual noise beyond the moderate motor/gearbox noise it currently has, stop using it and check for loose parts. For maintenance, you can clean the wheels occasionally to keep it running smoothly. If you need to make any repairs, refer to the spare parts included. And remember, if you're not satisfied with your purchase, you can get a refund within 30 days, just let us know.
