How do I set my R-50 Rainbird rotor sprinkler head?
When setting the Rainbird R-50 you want to ensure that the left fixed trip is where you want it. This position is indicated by the double ribs on the body below the cap. While sprinkler is up and operating, spread the vandal collar and slide it down the riser shaft (Do NOT remove the vandal collar). You may add arc by turning in a clockwise direction. Hold the riser in one hand. With the other pushdown on the nozzle turret and while still holding down, dial the additional arc you need.
