Using this model is quite simple. Just connect it to an analog DC power source and it'll run smoothly on your track. When handling the model, be gentle as it's a delicate item, especially the brass parts. For maintenance, keep it in a dry place to prevent rust. Clean the wheels regularly with a soft cloth to ensure minimal wheel wear and smooth operation. If you notice any unusual noise or issues, stop using it and check for loose parts. When shipping, we've already packed it securely, but if you need to move it yourself, make sure to use proper packaging materials to protect it. And don't forget, if you're not satisfied with your purchase, you can return it within 30 days for a full refund, minus the return shipping cost (except when the item arrives damaged).
