Hunter SRM Rotor Series

The Low Precipitation, Low Flow Rotor for Close-Range Applications

The SRM is Hunter's shortest-range rotor and was designed to offer a convenient and efficient alternative to spray heads. It is capable of working in tandem with larger rotors to combine big and small areas in a single zone. Utilizing the SRM where appropriate results in fewer sprinklers performing more efficient work at a more economical price. The SRM features a rack of six water-efficient nozzles all of which can be easily identified by its flow rates and installed and changed quickly and easily. This versatile rotor also includes a radius adjustment feature that fine-tunes the spray to keep water off driveways, walks, and other non-landscaped surfaces.

So far, very satisfied. If these new heads last as long as the previous Hunter heads, they will be the last heads I will have installed here.
I was looking for a Hunter head with a smaller than standard coverage radius.
This head fit the design.

HOW DO I ADJUST SPRINGER HEAD-SRM ?
James d on Jun 20, 2015
BEST ANSWER: Hi James,
Following is the instruction cut and paste from Hunter.

Arc Adjustment
(All SRM adjustable heads are PRESET to approximately 40°)
1. Rotate the nozzle turret counterclockwise to the left stop.
2. Now, rotate the nozzle turret clockwise to the right stop. This is the fixed 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 on top of the sprinkler.
2. While holding the nozzle turret at the right stop, turn the wrench clockwise. (Note: all
adjustments can be made with less than one full turn of the adjusting wrench.)
3. Wrench will stop turning when adjusted to the maximum arc (360°). Do not go past this stop.
4. Adjust to any arc between 40°-360°.

To decrease arc:
1. Insert the key end of the Hunter wrench into the adjustment socket.
2. While holding the nozzle turret at the right stop, turn the wrench counterclockwise.
3. Wrench will stop turning when adjusted to the minimum arc (40°). Do not go past this stop.
4. Adjust to any arc between 40°-360°.

Radius Adjustment
To decrease radius:
1. Turn nozzle-retainer/range-adjustment screw clockwise. This can reduce radius up to 25%.
2. If an even smaller radius is desired, install a smaller nozzle. This will affect precipitation rate.

To increase radius:
1. Turn nozzle-retainer/range-adjustment screw counterclockwise.
2. If larger radius is desired, install larger nozzle. This will affect precipitation rate.

how do i adjust sprinkler head?
James d on Jun 20, 2015
BEST ANSWER: There is an recessed hex drive set screw under the flap that holds the interchangeable spray tip. They spray tips can be swapped out with various GPM sized openings. There is also a screw on the top side that controls the arc length of the spray. The direction of the arc is adjusted by rotating the pop-up part of the body.
I need 3.0 Dark green nozzles for Hunter SRM 04. I need 10 Price please?
