Using this model is easy. Just connect it to a DC power source for analog control and watch it run. 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 wear and clean them gently if needed. Keep the motor clean to ensure smooth operation. If you notice any unusual noise, it might be a sign that the motor or gearbox needs a bit of attention. When storing the model, keep it in its box to protect it from dust and damage. Remember, it comes with an oil bunker insert for the tender, so you can use it to add a bit of realism.
