Home > How To Adjust A Signature Rotor Head – (Nelson)

This article covers the basics on how to adjust a Signature Rotor (formerly known as “Nelson” rotor). Keeping your rotors properly adjusted is an important part of irrigation system maintenance.

Arc Adjustments for Signature Rotors

Full Circle Adjustment:

  1. For full circle; leave black side up. No need to set collars.

Part Circle Adjustment:

  1. Remove the click-set disk and manually turn the rotor until nozzle points to the center of the desired watering area.
  2. Place Click-set disk in with the gray side up. Adjust collars to the desired angle.
  3. Memory Ring Protection – If the Signature rotor is manually turned past the set adjustment pattern, the memory ring will pop temporarily out of position while the sprinkler rotates around to its original part circle pattern. If the memory ring gets out of position while you are setting the pattern, remove the disk and rotate the ring with your fingers until the tab clicks into place.

Quick Adjust

  1. Ratcheting piston allows for quick turret adjustment for part-circle applications wet or dry.

Note: The ratcheting piston, wet or dry, will not break when you adjust the Signature rotor.
