Installing a nozzle on a rotor is relatively easy. The procedure is the same for the PGJ, SRM, PGP-ADJ, PGP Ultra and I-20 rotors. This video will teach you how to intall a nozzle for any Hunter rotors.
Insert the plastic end of the Hunter adjustment wrench into the lifting socket of the rotor and turn 90 degrees.
Pulling up the riser will allow access to the nozzle port for installation.
Insert the allen key (3/32) end of the Hunter adjustment wrench into the radius adjustment of the rotor. Turn counterclockwise no more than four times.
Pry the old nozzle out using the same key if necessary.
Visually check to make sure the nozzle screw is not blocking the socket where you are about to install the nozzle. Slip the nozzle into the nozzle socket, the nozzle socket is angled up 25 degrees.
After the nozzle is installed, turn the nozzle retainer screw clockwise far enough to hold the nozzle in place. Turning the nozzle retainer screw too far will result in reduced radius or loss of screw.
