Using this HO scale brass gas electric car is quite straightforward. Just connect it to your analog - DC power source, and it should start running well. When handling it, be careful not to touch the worn parts of the wheels to avoid further damage. For maintenance, you can periodically clean the gearbox like it was recently done. Check the glazing from time to time and if any more sections go missing, you might want to consider replacing them. When storing the car, keep it in its original box to protect it from dust and potential physical damage. Also, if you're shipping it back for a return, make sure to pack it well to avoid any new damages.
