“The partial circle rotors came preloaded with 2.0 gallon per minute nozzles plus an assortment of other replacement nozzles. The rotors were preset at more than 180 degree arcs. Adjusting the left stop is confusing. Rainbird says to not turn nozzlehead or you may strip the internal gears. They suggest you turn entire sprinkler on its 3/4 inch fitting. Other websites say to turn nozzle to right and then left to the desired location. Still others say to dial left for one full turn and then to desired location. While water was off I dialed to the right and then a full dial left before setting to desired location - always turning very slowly. The Rainbird works fine after those adjustments.”
