4. Adjust to any arc between 40°-360°.
Radius Adjustment
To decrease radius:
1. Turn nozzle-retainer/range-adjustment
screw clockwise using hex end of Hunter
tool or slot screwdriver. This can reduce
radius up to 25%.
2. If an even smaller radius is desired, install
a smaller nozzle. This will affect precipita-
tion rate.
To increase radius:
1. Turn nozzle-retainer/range-adjustment
screw counterclockwise using hex end of
Hunter tool or slot screwdriver.
2. If larger radius is desired, install larger
nozzle. This will affect precipitation rate.
Precipitation Rate Adjustment
To increase precipitation:
1. Remove existing nozzle.
2. Replace with larger size.
3. Adjust radius.
To decrease precipitation:

Questions and answers
How do you determine the correct nozzle to use? Is it the full length between sprinkler heads or half that length? How do you keep the head extended to insert a nozzle? Your instructions are not complete.
To determine the correct nozzle for the Hunter PGJ sprinkler head:
1. Identify your water pressure, ideally 40 psi.
2. Use the nozzle chart to match the nozzle number (e.g., 2.0) with the desired radius and flow rate.
- For example, a 2.0 nozzle at 40 psi sprays 25 feet and uses 2.2 gallons per minute.
3. Choose a nozzle based on the needed spray distance and water flow.
4. Install the nozzle and adjust the set screw if needed to control the spray distance.
