Using this model is easy. Just connect it to a DC - analog power source and watch it run smoothly on your track. When handling, be gentle as it's a fragile brass model. For maintenance, regularly check the wheels for any debris or excessive wear. You can use a soft, dry cloth to clean the body and windows. Store it in the original box and foam when not in use to protect it from damage. If you have any issues during operation, like unusual noise or stalling, first check the power connection. If the problem persists, contact us for further assistance. Remember, we offer a 30 - day money - back guarantee if you're not satisfied.
