Product Description

MP Rotator Tool

This tool is used to adjust both the arc and the radius of MP Rotators. Please note, this tool is not required for adjustments. All adjustments can be made by hand.

Arc Adjustment

First, install the MP Rotator with the left edge indicator 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 the MP Rotator is tightened.

Next, with the MP Rotator operating and in pop-up position, rotate the arc adjustment ring. turning the ring clockwise will increase arc, counter clockwise will decrease the arc.

 

Radius Adjustment

Factory setting is for full radius, and the radius can be reduced by 25% using the MP Rotator Tool or a small flat blade screwdriver.

To adjust, turn the screw clockwise, four full turns, to decrease the radius or counter clockwise, four full turns, to increase the radius.

Please 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 does.  To achieve maximum radius reduction with any MP Rotator model use a 30 PSI regulated spray body.
