In this article we will look at the rotational sweep or arc of the rotor. If you are looking at adjusting the radius or throw of your rotor, click here.
The arc adjustment screw is located on the top of the sprinkler head. It is the indented slot on the opposite side of the spraying, or nozzle side, of the sprinkler. There is a + symbol on the left side and a - symbol on the right side of the head. To increase the rotation you turn the screw to the plus sign, to decrease the rotation you turn it toward the minus sign. Logical, right? The trick here is the left margin on the head is a fixed position. Meaning you can't change how far it turns to the left without actually moving the head in the ground. You are only changing how far it sprays to the right. So if you are turning the screw toward the plus sign it will go farther to the right. These heads can go almost 360 degrees so the more you turn the screw to the plus sign the more you are increasing that right rotation. Alternately, the more you turn toward the minus sign the smaller your rotation to the right will be. Make small adjustments and check how it works before making additional turns.
