Put the citrus fruits into the appropriate cup. Press the start button, but remember the working time should not exceed 1 minute.

The copper - wire motor gives it a long service life, but don't overuse it to ensure its durability. And that's all you need to know to enjoy fresh citrus juice with this great juicer!
