Hunter MP Rotator Adjustment Tool

This tool is used to adjust your Hunter MP rotator nozzles. The tool makes it easier to adjust the spray angle of each nozzle so they spray perfectly for each application.

Arc Adjustment

  1. Install the MP Rotator with the Left Edge Indicator pointing to the left side of the desired watering pattern.
  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.

Radius Adjustment

Factory setting is for full radius, and the radius can be reduced by 25%. With the MP Rotator tool 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.
