Unscrew the radius adjustment screw until it clears the clears the nozzle. Use a sheet rock screw and thread it into the nozzle hole and pull it out. It will damage the nozzle, so if you plan on reusing it, this won't work. The other option is to turn the zone on and undo the screw. If you have enough pressure, the nozzle will shoot out. Keep an eye out for where it goes!
