Using this HO scale brass model is straightforward. Connect it to a DC power source as it has analog DC - only control. When running it, don't be too alarmed if you notice a bit of hesitation, but if it gets worse, you might want to check the motor. As for maintenance, keep it in a dry place to prevent further tarnish. If you decide to install the spare parts or boiler weight, do it carefully. For the gearbox, you can clean and replace the lube periodically as it was recently done. When handling the model, be gentle due to its fragile nature. And if you need to ship it back, make sure to follow the return policy and use proper packing to avoid damage.
