Using this freight motor is easy. Just connect it to your analog DC power source, and it'll start running smoothly. Since it has movable side doors, you can open and close them for a more realistic look. When handling the model, be gentle as it's a fragile item. Avoid dropping it or applying too much force. For maintenance, keep it in a dry and clean place. You can use a soft cloth to gently wipe the body to prevent dust buildup. Check the wheels regularly for any signs of wear, although currently the wheel wear is almost none. If you notice any issues with the motor noise or its running performance, feel free to contact us. And remember, when you're shipping it back (if needed), make sure to use proper packaging to avoid damage.
