Using this HOn3 brass model is easy. Just connect it to an analog - DC power source and watch it run. When handling the model, be gentle as it's a fragile item. Keep it away from sharp objects and rough surfaces to avoid scratches. For maintenance, clean the wheels regularly with a soft, dry cloth to keep the movement smooth. Check the motor in the tender from time to time for any signs of wear. If you notice any issues with the gearbox noise or the running performance, stop using it and contact us. When storing, keep it in the original box and insert to protect it from dust and damage. And remember, if you're not satisfied, we have a 30 - day money - back policy.
