How to Adjust a Hardie XL Series Rotor Sprinkler Head

Understanding Your XL Series Rotor

The Hardie XL series rotor is designed to rotate continuously across a set arc—it cannot be converted into a stationary spray head. If you need a fixed pattern, you would have to replace the rotor with a spray head or a fixed-arc nozzle. However, you can adjust the rotation arc to match your landscape.

Locating the Fixed Right Stop

Every XL rotor has a fixed right stop marked by a hash mark on the side of the riser, just below the nozzle turret. To find it, pull up the riser and align the arrow on the rubber cover with that hash mark. This reference point lets you position the right edge of the watering arc against hardscapes or property lines even when the riser is retracted.

Setting the Desired Arc

1. Insert a small flat-blade screwdriver into the adjustment hole marked with + and − arrows.
2. Push down firmly to engage the adjustment mechanism.
3. While holding the screwdriver down, turn it toward + to increase the arc or toward − to decrease it.
4. Watch the white indicator beneath the turret and the numbered scale on the rubber cover to gauge the arc setting.
5. Once the desired arc is reached, remove the screwdriver—the setting locks automatically.

Reducing Throw Distance

If the rotor throws water too far, use the same flat-blade screwdriver on the radius-reduction screw (usually located near the nozzle) to shorten the spray distance. This does not affect the rotation arc.

When to Consider a Different Head

If a stationary spray pattern is essential—for example, for a narrow planter or a corner—replace the XL rotor with a fixed-arc spray head or a rotary nozzle that can be set to 360° with a very small radius. Hardie (now Irritrol) offers compatible spray bodies that fit the same inlet.
