2. Trenching and Pipe Installation
Dig trenches to the appropriate depth for your local climate and pipe size. Lay the irrigation pipes, ensuring they are level and free of debris. Use appropriate fittings for connections.
3. Connecting the Sprinkler
Thread the PGJ-04 rotor onto the riser from the lateral pipe. Ensure the top of the sprinkler head is flush with the ground level when retracted. Hand-tighten the connection, then use a wrench for a final quarter-turn to secure it, being careful not to overtighten.
4. Nozzle Installation
The PGJ-04 comes with a variety of nozzles to achieve different flow rates and spray patterns. Select the appropriate nozzle for your specific needs.
- Pull up the riser to expose the nozzle socket.
- Insert the plastic key of the Hunter adjustment tool into the keyhole on the top of the sprinkler. Turn the key 90 degrees counter-clockwise to loosen the nozzle retention screw.
- Carefully remove the existing nozzle (if any) or insert the desired nozzle into the socket. Ensure it is seated correctly.
- Tighten the nozzle retention screw by turning the key 90 degrees clockwise.

5. Arc Adjustment (Setting the Right Stop)
The PGJ-04 is factory-set to rotate counter-clockwise from a fixed right stop. The right stop is the non-adjustable side of the spray pattern.
- Turn on the water supply to allow the sprinkler to pop up.
- Rotate the nozzle turret manually to the right stop. This is the fixed side of the arc.
- If the right stop is not aligned with the desired right edge of your watering area, you can adjust the entire sprinkler body. Dig around the sprinkler and rotate the entire body until the right stop is correctly positioned.
6. Arc Adjustment (Setting the Left Stop)
The left stop defines the adjustable side of the spray pattern.
- Insert the plastic key of the Hunter adjustment tool into the arc adjustment slot (marked with a plus/minus sign) on the top of the sprinkler.
- Turn the key clockwise to increase the arc (move the left stop further counter-clockwise) or counter-clockwise to decrease the arc (move the left stop closer to the right stop).
- The arc can be adjusted from 40 to 360 degrees.
7. Axuste do radio
The radius adjustment screw allows fine-tuning of the spray distance.
- Insert the metal end of the Hunter adjustment tool into the radius adjustment screw located on the top of the sprinkler.
- Turn the screw clockwise to decrease the radius or counter-clockwise to increase the radius.
- Do not turn the screw more than five full turns, as this can interfere with the spray pattern.
Instrucións de funcionamento
Once installed and adjusted, the Hunter PGJ-04 operates automatically with your irrigation controller. Ensure your controller is programmed correctly for desired watering times and durations.
