ARC ADJUSTMENTS
(N O N -OPPO S I N G N OZZL E M O DE L)
All I-40 group adjustable heads are preset to approximately 180°.
Sprinklers may be adjusted with water on or o. It is recommended
that initial adjustment be made before installation.
1. Using the palm of your hand, rotate the nozzle turret counter -
clockwise to left stop to complete any interrupted rotation cycle
(Fig. 1).
2.
side of the arc.The nozzle turret must be held in this position
for all arc adjustments.
To I ncrease Arc
1. Insert the key end of the Hunter wrench into the adjustment
socket (Figs. 2 & 3).
2. While holding the nozzle turret at the right stop, turn the
wrench clockwise. Each 360° turn of the wrench increases the
arc 45°.
3. Adjust to any arc between 50° and 360°.
4. Wrench will stop turning, or there will be a ratcheting noise,
when the maximum arc (360°) is reached.
5. When set to 360°, the sprinkler will rotate continually
counterclockwise.
To Decrease Arc
1. Insert the key end of the Hunter wrench into the adjustment
socket (Figs. 2 & 3).
2. While holding the nozzle turret at the right stop, turn the
wrench counterclockwise. Each 360° turn of the wrench
decreases the arc 45°.
3. Adjust to any arc between 50° and 360°.
4. Wrench will stop turning, or there will be a ratcheting noise,
when the minimum arc (50°) is reached.
Radius Adjustment
Insert the hex end of the Hunter wrench into the nozzle-retainer/
range-adjustment screw (Figs. 2 & 3).Turn the screw clockwise
into the stream of water to decrease the radius, or counterclockwise
to increase the radius.
P recipitation Rate Adjustment
Where excessively wet or dry areas are a problem, the
precipitation rate may be adjusted. Simply replace the existing
nozzle with a larger one to increase or a smaller one to decrease
the rate of precipitation.
Nozzle I nstallation
1. Insert the key end of the Hunter wrench into the lifting socket
of a pop-up sprinkler. Pull the riser up to gain access to the
nozzle socket.
2. Using the Hunter wrench, loosen the nozzle-retainer/range-
adjustment screw. If a nozzle is already installed in the
the water.
3. Discard nozzle if removed with pliers. Slip the desired nozzle
into the nozzle socket. Note that the socket is angled up 25°
(see Fig. 4).Tighten the nozzle-retainer/range-adjustment screw.

NO N-S TR IPPABLE BACKDR IVE
This sprinkler is designed with an internal device that prevents
damage to the internal gear drive if it should be turned by
vandals.This important feature works when the nozzle turret
is turning in either direction.This makes the sprinkler very
durable in all applications.
AUTO ARC RETUR N
This sprinkler is designed with an internal device that re-aligns
the arc if it is turned by vandals.This important feature works
when the nozzle turret is turning in either direction.When
forced outside of the originally set arc, the sprinkler takes the
shortest path back to the pattern without going completely
around.This saves the non-irrigated areas from getting wet!
Always a good thing!
