Hunter PGJ User manual

Arc Adjustment
(All PGJ adjustable heads are PRESET to
approximately 40°)
1. Rotate the nozzle turret counterclockwise
to the left stop.
2. Now, rotate the nozzle turret clockwise to
the right stop. This is the xed side of the
arc. The nozzle turret must be held in this
position for all arc adjustments.
To increase arc:
1. Insert the key end of the Hunter wrench
into the adjustment socket on top of the
sprinkler.
2. While holding the nozzle turret at the right
stop, turn the wrench clockwise.
3. Wrench will stop turning when adjusted to
the maximum arc (360°). Do not go past
this stop.
4. Adjust to any arc between 40°-360°.
To decrease arc:
1. Insert the key end of the Hunter wrench
into the adjustment socket.
2. While holding the nozzle turret at the right
stop, turn the wrench counterclockwise.
3. Wrench will stop turning when adjusted to
the minimum arc (40°). Do not go past this
stop.
4. Adjust to any arc between 40°-360°.
Radius Adjustment
To decrease radius:
1. Turn nozzle-retainer/range-adjustment
screw clockwise using hex end of Hunter
tool or slot screwdriver. This can reduce
radius up to 25%.
2. If an even smaller radius is desired, install
a smaller nozzle. This will affect precipita-
tion rate.
To increase radius:
1. Turn nozzle-retainer/range-adjustment
screw counterclockwise using hex end of
Hunter tool or slot screwdriver.
2. If larger radius is desired, install larger
nozzle. This will affect precipitation rate.
Precipitation Rate Adjustment
To increase precipitation:
1. Remove existing nozzle.
2. Replace with larger size.
3. Adjust radius.
To decrease precipitation:
1. Remove existing nozzle.
2. Replace with smaller size.
3. Adjust radius.
Note: Undamaged nozzles are reusable.

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.
