Using the Nella 0.8 hp Electric Tomato Squeezer is a breeze. First, plug it into a 115V, 60 Hz, 1 - phase power source. Then, place the tomatoes into the funnel. The machine will automatically separate the puree from the seeds and skin. For making meat, detach the head from the motor and attach the optional #22 meat grinder attachment. When it comes to maintenance, clean the 304 stainless - steel parts with warm, soapy water after each use. Make sure to dry them thoroughly to prevent rust. Avoid using abrasive cleaners on the machine. Store it in a dry place when not in use. If you encounter any issues, check the power connection and motor first.
