The MPTOOL rotator adjustment tool is used to change the variable arc and distance of spray coverage of the MP Rotator Nozzles. To achieve optimal results, replace all sprinklers on a zone with MP Rotators and adjust the run time accordingly. The precipitation rate of the MP Rotator is much lower than sprays and operating times will be similar to stream rotor zones. Features Install the MP Rotator with the Left Edge Indicator pointing to left side of the desired watering area. With the water on and the MP Rotator in the pop-up position; rotate Arc Adjustment Ring (clockwise) to increase the arc (counter-clockwise) to decrease the arc. 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. Downloads MPTOOL Instruction Guide MP Rotator Nozzle Support
