Nozzle Installation
1. Insert the plastic key end of the Hunter
wrench into the lifting socket of the sprin-
kler and turn 90°. Pull the riser up to gain
access to the nozzle socket.
2. Using the hex key of the Hunter wrench,
turn the radius adjustment screw coun-
terclockwise 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.
3. Slip the desired nozzle into the nozzle
socket. Note that the socket is angled up
Data represented test results in zero wind. Adjust for local conditions. Radius may be reduced up to 25% with adjustment screw (this may alter the uniformity of spray pattern).
Optimum performance is shown in bold type.
