A sprinkler system usually comes with a key. You use that key and insert it into the sprinkler head, and you should be able to adjust the arc and the amount of water the sprinkler throws out. It varies depending on your actual sprinkler brand, but a quick search of your manufacturer's website will show a step-by-step process on how to adjust sprinkler heads.
