The PGP® pop-up sprinkler should be
installed at nished grade as shown in
the illustration (Fig. 1).

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 xed side of the
arc. The nozzle turret must be held in this
position for arc adjustments. The right
stop does not change.

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.

2. While holding the nozzle turret at the right stop, turn the wrench counterclock-
wise. 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.

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.

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.

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 ow when the sprinkler is retracted.

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
tting 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.
It is not necessary to dig up and remove the whole
sprinkler to realign the right arc.
