Hunter I-80 User manual

INSTALLATION INSTRUCTIONS
I-80 GEAR-DRIVEN ROTORS
I-80 Arc Adjustments
Adjustments (not for “ON” opposing-nozzle models)
All I-80 adjustable arc rotors are preset to approximately
180°. Sprinklers can be adjusted with water on or o. It is
recommended that initial arc adjustments be made before
installation.
➊ Use your hand to rotate the nozzle turret counterclockwise
to the le stop to complete any interrupted rotation cycle.
② Next, 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 all arc adjustments.
➌ The ratchet feature allows the right xed stop to be moved
when water is o. Pull the riser up, grab the riser below
adjustment ring, and rotate the right xed arc stop to the
desired landscape alignment.
To Increase Arc
➊Slide the adjustment wrench
PN 382800SP onto the gray
adjustment ring below the nozzle
turret (Figure 1).
②While holding the nozzle turret
at the right stop, turn the wrench
counterclockwise.
➌Adjust to any arc between 60° and 360°. The wrench will
stop turning when the maximum arc (360°) is reached.
When set to 360°, the sprinkler will rotate continually
counterclockwise.
To Decrease Arc
➊Slide the adjustment wrench PN 382800SP onto the gray
adjustment ring below the nozzle turret.
②If the arc is set to less than 360°, hold the nozzle turret at
the right stop and turn the wrench clockwise.
➌If the arc is set to 360°, turn the wrench clockwise. Then
proceed with #2 above to complete the adjustment.
④Adjust to any arc between 60° and 360°. The wrench will
stop turning when the minimum arc (50°) is reached.
Radius Adjustment
Individual I-80 nozzles cannot be adjusted to reduce the radius.
To change the radius, install a larger or smaller nozzle.
Primary Nozzle Removal and Installation
➊ Insert the hex-key end of the Hunter wrench into the
primary nozzle “arrow” located on the top of
the rubber cover.
② Raise the nozzle-retainer screw by turning
counterclockwise. Raise the screw until the
screw clears nozzle opening.
➌ Using small needle-nose pliers, rmly insert
tip of pliers into the opening below the nozzle
(Figure 2). This action will collapse the nozzle’s
retaining hook (Figure 3). While gripping the
nozzle, pull outward to remove.
④ Slip the desired nozzle rmly into the nozzle
socket. Lower the nozzle-retainer screw to retain
the nozzle.
Short-Range/Mid-Range Nozzle Removal and
Installation
➊ Reference the I-80 and I-80-ON performance charts to
determine the correct nozzle part number and color.
② Use nozzle installation and removal tool PN
803700SP to service all short-range and
mid-range nozzles.
➌ When facing directly toward the nozzles,
short-range nozzles are on the le and mid-
range nozzles are on the right. To remove a
nozzle, rmly align and press the tool against it
while turning counterclockwise (Figure 4).
④To install the nozzle, engage the tool to the
nozzle. Then carefully align the nozzle to the
housing. Use care to prevent cross-threading
and turn clockwise (Figure 5).
➎ Each short-range and mid-range nozzle
has an alignment pointer. Turn the nozzle
clockwise until the pointer is facing the 12:00
position (Figure 6).
Stator Adjustments
All I-80 rotors with nozzles #10 through #20
have an automatic self-adjusting stator to control
rotation speed (Figure 7).
All I-80 rotors with nozzles #23 through #52 have a
manually adjustable stator to control rotation speed
(Figure 8).
When the primary nozzle size is changed, the stator
must be changed or adjusted to match the nozzle in
use. To make stator adjustments, rst remove the
riser assembly using the instructions below.
➊Remove the screen at the base of the riser by
grabbing, turning counterclockwise, and
liing away.
②Remove the stator assembly and adjust by
turning the black stator plate until the arrow
aligns with the nozzle in use (Figure 9).
➌Install the stator assembly with the black stator plate facing
the screen. Insert the screen and turn clockwise to lock.
Pop-Up and Riser-Mount Models
All I-80 rotors also have a traditional body cap that must be
unscrewed to gain riser assembly access. To facilitate easy riser
assembly removal, all I-80 rotors also include a removable snap
ring on the body cap. To access the riser assembly using the
snap ring, use tool 984400SP.
➊Insert the tool into the snap ring’s access
point (Figure 10). Press downward, slightly
twist the tool’s handle, and pull upward to
remove the snap ring (Figure 11).
②Engage the pull-up socket in the riser’s
logo cap using the Hunter wrench or
T-handle tool PN 319100SP. Pull upward to
remove the riser.
➌To install the riser assembly, insert the
riser into the body. First, install the snap
ring’s le side. Then press downward in a
counterclockwise direction.
Turf Cup Models
All I-80 rotors with turf cups have a removable
snap ring on the body cap to facilitate easy riser
assembly removal. To gain access to the snap ring,
the turf cup must be removed rst.

Use the pop-up riser removal instructions below to complete
riser removal and installation.
➊To install the turf cup to the top of the riser, the cup must
be correctly aligned with the top of the riser assembly.
②Locate the protruding vertical indicator on the outside of
the turf cup’s vertical surface near the top (Figure 17).
➌While holding the turf cup over the riser assembly, orient
the turf cup’s indicator mark to the riser’s nozzle retaining
screw.
④While maintaining this orientation, place the turf cup onto
the top of the riser. Then turn quickly clockwise to lock the
cup to the riser.

➊Pull the turf cup upward using at-nosed
pliers. Hold the riser assembly in the
popped-up position.
②Slide the adjustment wrench PN
991300SP onto the gray or black
adjustment ring below the nozzle turret.
Then release the cup downward (Figure 12
and Figure 13).
➌Hold the turret with the tool in one hand and
the riser and turf cup in the other. Remove the
cup with a quick counterclockwise turn and li
away (Figure 14).
④Use the Hunter wrench or T-handle tool PN
319100SP to engage the pull-up socket in
riser’s retainer cap (Figure 15).
➎Li the riser assembly slightly while removing
the adjustment wrench PN 991300SP. Then
lower the riser assembly into position
(Figure 16).
