Rain Bird® Simple Adjust Series Rotors

Operating Instructions for 32SA, 42SA, 42SA+, 52SA Series

1. Find the fixed LEFT edge.

First, turn the center cap of the rotor all the way to the right until it stops. Then turn it to the left until it stops. This is your fixed left edge. Rotate the entire rotor case to align the left edge into the correct position. This is the starting point from which water rotation will begin.

2. Adjust the Pattern to Increase/Decrease the Arc

The arc is preset to rotate 180º or a half circle. Using a flat-bladed screwdriver, turn the arc adjustment screw clockwise (+) to increase the arc or counterclockwise (-) to decrease the arc. The pattern is adjustable from 40º to 360º. Remember, when adjusting the arc while the rotor is operating, only turn the arc adjustment screw in the direction the rotor is already turning. Turning it against the direction it is already turning can damage the rotor by stripping the gears. These adjustments can be made while the water is on or off.

3. Adjusting the Radius (Distance of Throw)

With the water on or off, you can adjust the distance of throw. Using a flat-bladed screwdriver, turn the radius reduction screw to decrease the spray distance up to 25%.
