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 counter-clockwise 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 tem-
porary 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
counter-clockwise 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 neces-
sary to dig up and
remove the whole
sprinkler to realign
the right arc.
