How to Adjust Rain Bird Sprinkler Gears
- 1). Insert the supplied Rain Bird tool into the "Pull-Up" slot on the top-right side of the spray head. Twist the tool 90 degrees in either direction, and then pull up to lift the stem. Insert the desired nozzle into the exposed nozzle socket on the side of the stem. Different nozzles affect the precipitation rate of the spray head. Insert the tool into the "Radius Adjustment" screw on the top of the spray head and twist it clockwise to lock in the new nozzle.
- 2). Turn the spray head to the right until it stops turning and then to the left until it stops. The left point is the fixed left edge. This point may not be adjusted. Align the fixed left edge with the left border of the watering area.
- 3). Insert the tool into the "Arc Adjustment" socket below the label on the top of the spray head, hold the spray head in place and twist the tool clockwise to expand the arc or rotation range. When 360 degrees is reached, a ratcheting noise is heard or the tool stops turning. The sprinkler rotates continuously in one direction at the 360-degree setting.
- 4). Insert the tool into the Arc Adjustment socket, hold the spray head and turn the tool counterclockwise to decrease the rotation range. When the minimum range of 40 degrees is reached, a ratcheting noise is heard or the tool stops turning.
- 5). Insert the tool into the Radius Adjustment socket and turn the tool clockwise to lower the throw or water projection range by 25 percent. A lowered throw doesn't affect the amount of water flowing through the sprinkler.
- 6). Insert the Rain Bird tool into the "Flow Shut-Off" slot in the center of the spray head and twist it 180 degrees clockwise to shut off the flow of water to the sprinkler. Twist the tool 180 degrees counterclockwise to reopen the flow of water to the sprinkler.
