The results may be a wet walkway or a dry turf area if the right side of the arcs is not properly aligned.The right side arcs can be realigned.The sprinkler body assembly can be turned left or right to realign the stop.The soil around the sprinkler may need to be removed temporarily to allow you to grip the housing.

One way to reset the right arcs is to remove the internal assembly from the body.Attach the internal assembly back into the body with the nozzle aligned to the right side of the area you want to irrigate.You can adjust the left arcs to an appropriate setting after realigning the right arcs.
