The Hunter MP Rotator Adjustment Tool is used to adjust both the arc and the radius of MP Rotators. Please note, the MP tool is not required for adjustments. All adjustments can be done by hand.

• Quick & easy-to-use adjustment tool for MP Rotators


• Adjusts both the arc & radius

Arc Adjustment

• Install the MP Rotator with the left edge indicator pointing to the left side of the desired watering pattern


• With the MP Rotator operating & in the pop-up position, rotate the arc adjustment ring


• To increase the arc, turn the arc adjustment ring clockwise. To decrease the arc, turn it anticlockwise

Radius Adjustment

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

• Clockwise (4 full turns) to decrease the radius


• Anticlockwise (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 2 Bar (30 PSI) regulating spray body.A consistent operating pressure greater than 3.7 Bar (> 55 PSI) reduces the life of the sprinkler, increases rotation speed, reduces sprinkler uniformity and voids the trade warranty.
