Hunter MP Rotator Tool
- Install the MP Rotator with the Left Edge Indicatorpointing 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.
- 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.
Factory setting is for 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: Radius reduction is intentionally limited by a slip clutch mechanism 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.
