Arc Adjustment Procedure (Part-circle Models) ________________________________________ The 860S and 880S part-circle models have an adjustable watering arc from 30°–330° and are factory preset at 180°. The left side of the arc, located at the end of counterclockwise rotation, is non-adjustable (fixed). Therefore, all arc adjustments, whether increasing or decreasing, will change the right side of the arc, located at the end of clockwise rotation. Although the sprinkler arc can be adjusted dry (
