If you notice when you flip the lever the dies either open or close. Adjust to size if it's not there. Fill the thing with cutting oil, when the die is down it should rain on the pipe, completely covering the thread cutting, you need a ton of oil. Cut your threads, go one thread past the end of the dies, then open the dies with it still spinning. Don't stop the machine with the dies engaged. Spin a fitting on til it's hand tight, then count the turns as you spin it off. Adjust them til you get 3.5 turns ideally, 3 to 4 is usually close enough. Cut each wrong thread off, you need to set it cutting threads on just pipe, not chasing them deeper. Then you're ready to start cutting and threading your pieces once the die is correctly set.
