To Increase Radius
- Insert the plastic key end of the Hunter wrench into the lifting socket of the sprinkler and turn 90°. Pull the riser up to gain access to the nozzle socket.
- Using the hex key of the Hunter wrench, turn the radius adjustment screw counterclockwise to be sure it is not blocking the nozzle socket opening. If a nozzle is already installed, it can be removed by backing out the adjustment screw and turning on the water, or by prying outward under the nozzle.
- Slip the desired nozzle into the nozzle socket. Note that the socket is angled up 25° so that the nozzle range screw threads directly down. Then tighten the nozzle range screw. The arrow on the rubber cover will always indicate the location of the nozzle and direction of the water flow when the sprinkler is retracted.
Removing Filter Screen for Cleaning
The filter screen on a PGJ rotor can be easily accessed and cleaned by removing the internal assembly and flushing water through the filter.
