Using this HO brass model is straightforward. Just connect it to an analog - DC power source and it should run well. When handling, be gentle as it's a fragile item. For maintenance, check the wheels regularly for any excessive wear and clean them gently if needed. Keep the motor and gearbox clean to reduce noise. Store it in the original box and foam when not in use to protect it from damage. If you notice any issues during operation, contact us right away. And remember, if you're not satisfied, you can return it within 30 days for a full refund (you'll pay return shipping unless it arrives damaged).
