Adjustable heads are preset to approximately 180 degrees. Sprinklers may be adjusted with water on or off. It is recommended that initial adjustments be made before installation.
Note: The right stop does not change.
To Increase the Arc
To Decrease the Arc
Radius / Distance of Throw
Insert the steel hex end of the Hunter wrench into the radius adjustment screw. Turn the screw clockwise (into the stream of water) to decrease the radius, or counterclockwise to increase the radius. Radius can be reduced up to 25%.
Caution: Turning the adjustment screw clockwise more than five full turns may result in a lost radius adjustment screw.
Aligning the Right (Fixed) Side of Arc
If the right side of the arc is not properly aligned, the results may be a wet walkway or a dry turf area. The right side arc can easily be realigned. One way to realign the right stop is to turn the whole sprinkler body assembly and the fitting below it, left or right to the desired position. This may require temporary removal of the soil around the sprinkler to allow you to grip the sprinkler housing.
Another way to reset the right arc is to unscrew the body cap counterclockwise and remove the internal assembly from the body. Once removed, rotate the nozzle turret to the right stop, screw the internal assembly back into the body with the nozzle aligned to the right side of the area you want irrigated. At this point you have realigned the right arc stop, and you can adjust the left arc to an appropriate setting.
Note: It is not necessary to dig up and remove the whole sprinkler to realign the right arc.
