Setting the Left Edge of the Arc

To set the left edge of the spray arc on your Rain Bird 42SA+ rotor sprinkler, begin by identifying the center cap on the top of the sprinkler head. This cap serves as the primary control for adjusting the arc’s left edge, which marks the starting point of the sprinkler’s rotation. Initially, the left edge is fixed and needs to be located by rotating the center cap all the way to the right until it stops. Then, turn the cap to the left until it stops. This position represents the fixed left edge. This fixed left edge cannot be adjusted, but it is important to understand as a starting point for adjusting the right edge of the arc. The left edge defines the path and provides a precise point; By understanding the left edge, you will have a proper base for adjusting the rest of your desired watering area. This step is crucial before making changes to the right edge, ensuring that your adjustments are accurate and effective for optimal lawn coverage. This process is important to ensure the sprinkler covers the intended area.

Adjusting the Right Edge of the Arc

After establishing the fixed left edge, you can adjust the right edge of the spray arc on your Rain Bird 42SA+ sprinkler. This adjustment is crucial for controlling the overall area covered by the sprinkler. Locate the adjustment mechanism, which is the center cap on the sprinkler head. Using a flathead screwdriver, carefully turn the center cap. To move the right edge clockwise, turn the cap in a clockwise direction; to move it counterclockwise, turn the cap in a counterclockwise direction. The right edge determines the end point of the sprinkler’s rotation. Adjust it to ensure that water is only applied to the desired area, avoiding areas such as sidewalks, driveways, or buildings. This precise adjustment helps conserve water and promotes efficient irrigation. Make small adjustments and monitor the spray to ensure you achieve the desired coverage. Fine-tuning the right edge will help with overall performance. This ensures the most effective water distribution. By correctly adjusting the right edge, you can maximize the efficiency of your sprinkler system.

Adjusting the Spray Distance

The Rain Bird 42SA+ allows for easy adjustment of the spray distance, ranging from 26 to 38 feet; This is achieved using a radius reduction screw, typically located on the top of the sprinkler head. Adjustments are made with a flathead screwdriver.

Identifying the Radius Reduction Screw

The radius reduction screw on the Rain Bird 42SA+ rotor sprinkler is a crucial component for adjusting the spray distance. This screw, typically located on the top of the sprinkler head, is designed to regulate the water flow and, consequently, the distance the water is thrown. It’s usually a small, flat-head screw, often made of plastic or metal, and is distinct from other adjustment mechanisms on the sprinkler. Look for a screw near the nozzle area, usually within a recessed area or clearly marked with a plus and minus symbol, indicating the direction to turn for increasing or decreasing the spray radius. This screw is easily accessible and designed for simple adjustments using a standard flathead screwdriver. The screw may be positioned directly on the nozzle, or adjacent to it, depending on the specific model and design variations. It’s essential to locate this screw accurately before attempting to adjust the spray distance, as other screws might control the arc or other aspects of the sprinkler’s performance. Identifying the radius reduction screw correctly ensures that you are modifying the spray distance and not another parameter of the sprinkler’s operation.

Using a Flathead Screwdriver for Adjustment

A flathead screwdriver is the primary tool for adjusting the spray distance of the Rain Bird 42SA+ rotor sprinkler. To begin, gently insert the flathead screwdriver into the radius reduction screw, ensuring it fits snugly. To reduce the spray distance, turn the screw clockwise, which restricts the water flow and shortens the throw. Conversely, turning the screw counterclockwise increases the spray distance by allowing more water to pass through the nozzle. Make small, incremental adjustments, as a slight turn can result in a noticeable change in the spray range. Observe the sprinkler’s performance after each adjustment and fine-tune as needed to achieve the desired coverage. When turning the screw, be gentle and avoid forcing it to prevent damage to the adjustment mechanism. It is recommended to make adjustments while the water is running to observe the spray distance directly, this will help to dial in the correct distance for your specific watering needs. This process ensures that you achieve the optimal watering distance and prevent water waste by ensuring you are only watering the areas that need it.

Nozzle and Maintenance

The Rain Bird 42SA+ nozzle can be changed using a flathead screwdriver and needle-nose pliers. It also features a self-flushing action during pop-down, which clears debris and maintains optimal spray efficiency. Regular maintenance ensures consistent performance.

Changing the Nozzle on the 42SA+

To change the nozzle on your Rain Bird 42SA+ rotor sprinkler, you’ll need a flathead screwdriver and a pair of needle-nose pliers. First, use the screwdriver to gently lift the nozzle housing, exposing the radius reduction screw. Next, turn the radius reduction screw to release the nozzle, which should now be easily removable. If needed, use the needle-nose pliers to grip and pull the nozzle out. When installing a new nozzle, align it correctly within the housing and make sure it’s securely in place before retracting the nozzle housing. This process is straightforward and allows for easy customization based on your lawn’s specific watering needs. Additionally, ensure that the nozzle is firmly installed to prevent any issues with water distribution. Remember to always turn off the water supply before changing nozzles. Following these steps helps maintain the efficiency of your sprinkler system.

Understanding the Flushing Feature

The Rain Bird 42SA+ incorporates a self-flushing feature designed to clear debris and maintain optimal spray efficiency. This feature manifests as a slight leak through the adjustment hole when the rotor head retracts. This is not a malfunction but a deliberate design to flush out any particles that may have accumulated during operation. The flushing action ensures that the internal mechanisms remain free from blockages, which can lead to uneven watering patterns or premature wear. This self-cleaning process is crucial for the longevity and consistent performance of the sprinkler. It reduces the need for manual cleaning and keeps the sprinkler operating efficiently. The flushing feature is a built-in safeguard and should not be mistaken for a leak. It is a vital part of the maintenance, keeping the sprinkler operating smoothly and ensuring a reliable watering experience for your lawn. Regular inspection can help identify if the flushing function is working properly.
