PGP InstallatIon:
The PGP pop-up sprinkler should be
installed at finished grade as shown
in the illustration (Fig. 1).
arc adjustments:
Adjustable heads are preset to
approximately 180˚. Sprinklers may
be adjusted with water on or off. It is
recommended that initial adjustments be
made before installation.
1. Using the palm of your hand, rotate the
nozzle turret counterclockwise to the
left stop to complete any interrupted
rotation cycle (Fig. 2).
2. Rotate the nozzle turret clockwise to
the right stop. This is the fixed side of
the arc. The nozzle turret must be held
in this position for arc adjustments.
The right stop does not change.
to Increase the arc:
1. Insert the plastic key end of the Hunter
wrench into the adjustment socket (Fig. 3
& 4).
2. While holding the nozzle turret at the right
stop, turn the wrench clockwise. Each full
360˚ turn of the wrench will increase the
arc 90˚.
3. Adjust to any arc between 40˚ and 360˚
(Fig. 5).
4. The wrench will stop turning, or there will be a ratcheting noise, when the
maximum arc of 360˚ (full circle) has been reached.
to Decrease the arc:
1. Insert the plastic key end of the Hunter wrench into the adjustment socket
(Fig. 3 & 4).
2. While holding the nozzle turret at the right stop, turn the wrench counter-
clockwise. Each full 360˚ turn of the wrench will decrease the arc 90˚.
3. Adjust to any arc between 40˚ and 360˚ (Fig. 5).
4. The wrench will stop turning, or there will be a ratcheting noise, when the
minimum arc of 40˚ has been reached.
RaDIUs / DIstanCE oF tHRoW
Insert the steel hex end of the Hunter wrench into the
radius adjustment screw (Fig. 6). Turn the screw clockwise
(into the stream of water) to decrease the radius, or
counterclockwise to increase the radius. Radius can be
reduced up to 25%.
Caution: Turning the adjustment screw clockwise more
than five full turns may result in a lost
radius adjustment screw
.
PRECIPItatIon RatE aDJUstMEnt
If you have excessively wet or dry
areas, you can change the nozzle in the
sprinkler to increase or decrease the
precipitation rate. For dry areas, install
a larger nozzle. For wet areas, install a
smaller nozzle.

noZZlE InstallatIon
1. 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 (Fig. 8).
2. Using the hex key of the
Hunter wrench, turn the radius
adjustment screw (Fig. 6)
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
pulling outward on the nozzle
“ears” with a pair of needle-
nosed pliers.
3. Slip the desired nozzle into the
nozzle socket (Fig. 7). Note that
the socket is angled up 25˚. The
“ears” should be adjusted so that
the nozzle range screw threads
directly down between them.
Then tighten the nozzle range
screw. The raised bump with
an arrow on the rubber cover will always indicate the
location of the nozzle and direction of water flow when
the sprinkler is retracted.
alIGnInG tHE RIGHt (FIXED) sIDE oF aRC
If the right side of the arc is not properly aligned, the
results may be a wet walkway or a dry turf area. The
right side arc can easily
be realigned. One way to
realign the right stop is to
turn the whole sprinkler body
assembly and the fitting
below it, left or right to the
desired position. This may
require temporary removal of
the soil around the sprinkler
to allow you to grip the
sprinkler housing.
Another way to reset the
right arc is to unscrew the
body cap counterclockwise
and remove the internal assembly from the body. Once
removed, rotate the nozzle turret to the right stop, screw
the internal assembly back into the body with the nozzle
aligned to the right side of the area you want irrigated
(Fig. 9). At this point you have realigned the right arc
stop, and you can adjust the left arc to an appropriate
setting.
note:
It is not necessary to dig up and remove the
whole sprinkler to realign the right arc.
