I-20 Rotary Sprinkler Adjustment Instructions
Aligning the Right Fixed Side of Arc
The right side of the arc can be realigned to avoid wet walkways or a dry turf area. One way to realign the right stop is to turn the whole sprinkler body assembly and the fitting below. This may require temporary removal of the surrounding soil.
Another way to reset the right side of the arc is to unscrew the body cap and remove the internal assembly from the body.
Once removed, rotate the nozzle turret to the right stop and screw the internal assembly back into the body with the nozzle aligned to the right side of where you want irrigated. At this point you have realigned the right arc stop and can adjust the left arc to the appropriate setting.
Adjustable heads are preset to approximately 180 degrees and can be adjusted with the water on or off. It is recommended that initial adjustments be made prior to installation.
The right stop is fixed therefore cannot be adjusted.
Increasing the Arc
Decreasing the Arc
Be careful not to turn the wrench too far, if you start to hear a ratcheting noise you’ve gone too far and are in danger of damaging internal components.
Turning Flow On/Off
Insert the plastic end of the Hunter adjustment wrench into the FloStop adjustment socket. A rotation clockwise 90 degrees will stop the flow of water, a rotation counterclockwise will allow the flow of water.
