Using your Nella Juice Extractor is easy. First, make sure it's plugged into a 110V outlet using the NEMA 5 - 15P plug. Choose the appropriate citrus crown (small or large) based on the size of the fruit you're using. Place the fruit on the crown and let the machine do its job. It'll extract fresh and delicious juice for you. When you're done, don't forget to unplug the machine. For cleaning, remove the citrus crown and wash it under running water. Wipe the rest of the machine with a damp cloth. Make sure the machine is completely dry before storing it. Keep it in a cool, dry place. Avoid using abrasive cleaners on the machine as it might damage the surface. And always follow the electrical safety rules when using it.
