Adjusting Toro 570 Variable Arc Nozzles

Turn the Collar, Not the Top, to Change Arc

The adjustment ring is just below the nozzle top. Grip the nozzle body with one hand and turn the ring with the other. Practice with water off. Turning one way increases arc, the other decreases. If the top blows off, you’re turning the wrong part.
