I-40/41/42/43
Gear-Driven Sprinklers
ARC ADJUSTMENTS
All I-40 group adjustable heads are preset to
approximately 180°. Sprinklers may be adjusted
with water on or off. It is recommended that initial
adjustment be made before installation.
1. Using the palm of your hand, rotate the
nozzle turret counterclockwise to left stop to
complete any interrupted rotation cycle.
(Fig. 1).
2. Rotate the nozzle turret clockwise to right
stop. This is the xed side of the arc. The
nozzle turret must be held in this position for
all arc adjustments.
To Increase 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 counter-clockwise.
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 (40°)
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 counter-clock-
wise to increase the radius.
Precipitation 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 Installation
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 sprinkler, it may
now be removed by briey turning on
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.

Note: All precipitation rates are calculated for 180 degree
operation. For the precipitation rate for a 360 degree sprinkler,
divide by 2. Precipitation rates for the ON model are calculated
at 360 degrees.

Each nozzle can be identified by
the number of raised ridges on the
inside surface of the nozzle.
Example: 2 ridges = # 42 nozzle
I-40 Ultra = 3 minutes (approx.)
I-40 Ultra High Speed = 1 minute (approx.)
