Using this HO scale brass ALCO model train switcher is quite straightforward. Just connect it to your analog - DC power source and it will start running. When handling the model, be gentle as it's a fragile item, especially since it's made of brass. For maintenance, you can use a soft cloth to clean the body and wheels regularly to keep the minimal tarnish from getting worse. Check the motor and gearbox periodically for any signs of excessive noise. If the noise level goes beyond 5 out of 10, it might be a good idea to have it inspected. When storing the model, keep it in the original box and foam to protect it from damage. And remember, if you're not satisfied with your purchase, you can take advantage of our 30 - day, no - questions - asked money - back policy, though you'll be responsible for return shipping costs unless the item arrives damaged.
