Adjustable heads are preset to approximately 180°. The I-90 can be adjusted from 40-360 degrees. Sprinklers may be adjusted with water on or off. It is recommended that initial adjustment be made before installation.
Note: It is not necessary to disassemble the sprinkler to make adjustments.
To Increase Arc
To Decrease 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 can easily be realigned. One way to realign the right stop 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, insert 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 realigned the right arc stop, and you can adjust the left arc to an appropriate setting.
If you have excessively wet or dry areas, you can change the nozzle in the sprinkler to increase or decrease the precipitation rate. For dry areas, install a larger nozzle. For wet areas, install a smaller nozzle.
Note: Refer to the Nozzle/Stator Chart below for nozzle and stator settings.
