To get the best coverage for your rotating sprinkler heads while avoiding areas you don’t need to water (sidewalks, parking lots, houses, etc.), you may have to adjust the rotor to get the arc at the correct angle. Many rotors come with their arcs set to the lowest degrees for that model (often 40 degrees). Most rotors can go up to 360 degrees for a full circle, if needed. Here are three simple steps to adjust the arc of a sprinkler. 1. ** Turn the system on** Adjustments are made when the sprinkler is watering so you can see the change you are making. 1. ** Open the top cover and turret** Stand behind the rotor you want to adjust. Press the top cover in and rotate it to the left until it stops. If your rotor has a turret, rotate the turret to the right until it stops, and hold the turret in this position until you’ve finished rotating the arc. (Consult the manufacturer’s manual for specific directions about the model you have.) 1. ** Adjust the arc** Find the keyhole, located near the plus/minus signs. Insert the [key](https://www.ewingirrigation.com/hunter-sprinkler-adj-key) or [screwdriver](https://www.ewingirrigation.com/products/tools-accessories/tools-short-handle/tools-screw-nut-drivers) (depending on manufacturer) and rotate: to the right for a larger arc or the left for a smaller arc. Watch the sprinkler as you adjust the key to ensure you have the correct angle. When you have the desired angle, remove the key. Once you’ve completed these three steps, your sprinkler will be watering at the angle needed for more efficient irrigation! Do you have tips for adjusting the arc of a sprinkler?
