Leaving a toy crane machine powered on continuously is generally not recommended for safety, longevity, and economic reasons. While modern machines have safety features, several risks persist. First, electrical components like power supplies and wiring can overheat over time, especially in poorly ventilated areas, increasing fire hazard potential. Second, constant operation leads to accelerated wear of motors, gears, and belts, resulting in more frequent breakdowns and costly repairs. Third, it represents an unnecessary waste of electricity, adding to your energy bill. For commercial arcades, some machines may stay on during business hours but are typically shut down overnight for maintenance and safety checks. At home, the best practice is to turn the machine off when not in use. Always ensure the machine is placed on a stable surface, has proper ventilation, and is connected to a surge protector. Regularly inspect cords for damage and follow the manufacturer's guidelines. Prioritizing these steps ensures fun and safe operation while protecting your investment.
