Full-circle riser assemblies can be inserted into the rotor’s body without regard to arc orientation. Insert the riser,
screen rst, into the rotor’s body until it comes to a stop. Next, install the upper snap-ring referencing instructions

Adjustable part-circle risers must be inserted such that the arc setting aligns to the area to be irrigated. All Hunter
adjustable arc rotors have a xed stop on the right side of the arc and an adjustable stop on the left side of the arc.
Rotate the nozzle housing (turret) back and forth to nd the right xed stop. With the riser positioned to the right
xed arc stop, oriented and point the long-range nozzle to the right side of the landscape area to be irrigated. Drop
the riser into position within the rotor’s body.
For convenience of installation, new rotors from the factory are set to approximately 180 degrees and the long-
range nozzle is positioned to the right x side of the arc. Arc adjustments can be made with the riser in hand or, after
instalation – dry or, while the rotor is in operation.
Refer to the section earlier in this manual to learn more about the arc adjusting procedures.

Hunter Golf TTS rotors have upper snap-rings with an integrated wiper to help protect the riser and riser seal from
external contamination. It is important to follow these installation instructions to maximize the effectiveness of this
design.

Hold the snap-ring in front of you with the wiper seal facing up and the snap-ring open ends at the top. The snap-ring
end on the left must be installed rst (g 65). Lay the snap-ring on top of the rotor and use the left thumb to force the
left open end of the snap-ring into the upper snap-ring groove within the body (g 66). Once engaged, the remaining
portion of the snap-ring can be installed by pressing in a counter-clockwise motion around the snap-ring (g 67).
