PGP nozzles


I have just completed the installation of my lawn irrigation system. I have a little problem with the PGP rotors.

The nozzle will not stay in the heads. The nozzle will actually launch itself out of the head. Is there a setting on the rotor to stop this? Zone Example: 155' at 1" all the way to the head. Reduced down to a 3/4" at the head. 5 heads on this line. Main comes directly from the well with a pump that delivers the amount of water you need when you want it. Inside, the well controll is set to 60 PSI. I cannot believe that I have to much water presure.

Any ideas on how to keep the nozzle in the heads?

You need to adjust the radius adjustment screw until it comes into contact with the nozzle. Using the hex key of the Hunter wrench, turn the radius adjustment screw (The raised bump with an arrow on the rubber head cover) clockwise until it makes contact with the nozzle.
