MP Rotator - Adjustment

1. Install the MP Rotator with the Left Edge Indicator (flat side of nozzle) pointing to the left side of the desired watering pattern. The Hunter Pro-Spray two piece ratcheting riser will allow you to align the riser by twisting in either direction after MP Rotator is tightened.
2. With the MP Rotator operating and in the pop-up position, rotate the Arc Adjustment Ring. Turning the Arc Adjustment Ring clockwise will increase the arc, counter clockwise will decrease the arc.

Note: Adjustment can be done with the MP Rotator Tool (MPTOOL) or by hand.

The factory setting is for a full radius, and the radius can be reduced by 25%. With the MP Rotator tool (MPTOOL) or a small flat-bladed screwdriver, rotate the Radius Adjustment Screw:

• Clockwise (4 full turns) to decrease the radius
• Counter-clockwise (4 full turns) to increase the radius

Note: A slip clutch mechanism intentionally limits radius reduction to ensure reliable rotation. To prevent damage during adjustment, the MP Rotator does not completely shut off like a spray nozzle. To achieve maximum radius reduction with any MP Rotator model use a 30 PSI (2 BAR) regulating spray body.
