Using this hand dryer is a breeze. Just place your hands under the dryer, and it will automatically start drying them. When you're done, remove your hands, and it will stop. It's important to keep the dryer in a dry area to prevent any electrical issues. Don't try to modify the dryer on your own as it may void the warranty and pose a safety risk. For maintenance, wipe the exterior regularly with a soft, dry cloth. If there's a lot of dirt or grime, you can use a mild detergent, but make sure to dry it thoroughly afterwards. Also, check the power cord periodically for any signs of damage.
