Rain Bird 952E

The Rain Bird 952E is an electric valve-in-head golf rotor for large turf irrigation. The listed GRE952860 configuration corresponds to an 80 psi pressure-regulated 952E with a #60 front nozzle.

Key features

• Rapid-Adjust full-circle or adjustable part-circle operation from 30° to 345°
• MemoryArc retains the part-circle setting when switching between operating modes
• Self-adjusting stator helps maintain a consistent rotation speed as flow changes
• Top-serviceable rock screen and replaceable valve seat

Arc adjustment guide

Use a 6.5 mm flat-blade screwdriver and make adjustments with the rotor off. Do not force the full/part-circle adjustment screw.

1. Turn the full/part-circle adjustment screw to the part-circle icon.
2. Arc A: the left-hand edge of the arc is fixed. The arc adjustment screw moves the right-hand edge.
3. Arc B: the right-hand edge is fixed. The arc adjustment screw moves the left-hand edge, and works in the reverse direction to the marks shown on the turret.
4. To change between Arc A and Arc B, temporarily select full-circle, rotate the turret in its direction of rotation until the nozzle points between the edges of the required arc, then return the adjustment screw to part-circle.
5. For full-circle watering, turn the adjustment screw to the full-circle setting. The stored Arc A and Arc B settings are retained for later use.

After setting the arcs, run the rotor manually and fine-tune as required.
