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.
note: It is not necessary to disassemble the sprinkler to make adjustments.
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.

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.
