Using the Nella Heavy - Duty 0.5 hp Elite Potato Peeler is easy. First, make sure it's plugged into a 110V/60Hz/1Ph electrical outlet using the included NEMA 5 - 15P plug. Then, put the potatoes into the peeler. It can handle up to 22 lbs at a time. Switch it on, and it'll start peeling the potatoes quickly. When it's done, simply turn it off. For cleaning, since it's made of stainless steel, you can wipe it down easily with a damp cloth. As for maintenance, check the parts regularly for any signs of wear. Keep it in a dry place when not in use to prevent rust. Also, don't overload it with more potatoes than its 22 - lb capacity, as this could affect its performance.
