Using this HO brass model is straightforward. Just connect it to your analog DC power source and watch it run on your track. It's a smooth - running engine, so you'll enjoy a quiet and steady operation. When handling the model, be gentle as it's a fragile item, especially since it's made of brass. For maintenance, regularly check the wheels for any signs of excessive wear. Wipe the body of the model with a soft cloth to keep it clean. If you notice any issues with the motor or the couplers, don't try to fix it yourself. Instead, contact a professional or us for advice. Keep it stored in the original box and foam when not in use to protect it from damage. Remember, it has a non - working headlight, so don't expect it to light up. Also, follow the shipping and payment rules we've set. If you're not satisfied with your purchase, let us know within 30 days for a hassle - free refund, but you'll be responsible for return shipping unless the item arrives damaged.
