Using this model is quite straightforward. Just connect it to an analog DC power source and watch it run. It operates well under normal conditions. As for the missing brake shoes, it doesn't affect basic operation but be aware of its braking performance. When handling, be gentle as it's a brass model and can be fragile. For maintenance, keep it in a dry and clean place. You can use a soft cloth to dust it off. If you notice any excessive noise from the motor or gearbox, it might be a good idea to have it checked by a professional. Also, always store it in the original box and foam to protect it from damage. And remember, if you're not satisfied with your purchase, you can return it within 30 days for a full refund, just pay the return shipping unless it arrived damaged.
