Using this Nella tomato squeezer is easy. First, plug it into a 115V power outlet. Then, put your tomatoes into the funnel. The machine will do the rest, separating the puree from the seeds and skin. For making meat, detach the head from the motor and attach the optional #12 meat grinder attachment. When using, make sure to place it on a stable surface. After use, unplug the machine and clean it. You can wash the 304 stainless steel parts with warm, soapy water. Don't submerge the motor in water. Keep the machine in a dry place to prevent rust and damage.
