Using this model is easy. Just connect it to an appropriate analog DC power source and watch it run on your track. When handling it, be gentle as it's a fragile item. Avoid dropping or rough handling. For maintenance, regularly check the wheels for any debris or excessive wear. You can clean the wheels with a soft, dry cloth. If you notice any unusual noise from the motor or gearbox, it might be a sign to have it checked. Keep it stored in a dry and dust - free place when not in use. And remember, if you're not satisfied with your purchase, you can return it within 30 days for a full refund, though you'll be responsible for return shipping costs unless the item arrived damaged.
