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.
