Rainbird pop-up sprinklers provide even, continuous watering to zones within irrigation systems. They are fully enclosed, gear-driven and will pop up from the ground only when needed for watering, returning to their low-profile position once finished. Rainbird sprinklers are factory set to a 180 degree spray arc pattern and can be adjusted from 40 to 360 degrees. They are easy to operate and can be adjusted either dry or wet with a simple flathead screwdriver.
Turn the center cap of the sprinkler to the right, using the palm of your hand, until it stops. Then turn the center cap to the left until it stops. This is the fixed left edge of the sprinkler.
Adjust the arc dial with the screwdriver. Turn the dial clockwise to increase the arc and counterclockwise to decrease it. Do not adjust the sprinkler past 40 or 360 degrees, as this can cause binding of the gears.
Adjust the spraying distance by turning the radius screw in the center cap with the screwdriver. Turn the screw clockwise to reduce the radius and counterclockwise to increase it.
Change out the nozzle of the sprinkler by first backing the radius screw out. Press the tab on the nozzle with the screwdriver to remove the nozzle from the sprinkler. Insert a new nozzle and screw the radius screw back in place.
