Using this model is quite simple. Just connect it to an analog DC power source and it will start running smoothly. Make sure the power supply is stable to avoid any sudden stops. When handling the model, be gentle as it's a delicate item. For maintenance, every few months, check the gearbox. If you notice the movement is getting a bit rough, you can remove the old grease and add new grease like it was done during the recent service. Also, keep an eye on the rubber drive tube for any signs of wear and replace it if necessary. When storing the model, put it back in the original box with the foam to protect it from scratches and damage.
