I-50 ROTOR SUPPORT

I-50 Arc Adjustments

Adjustments (not for “ON” opposing-nozzle models)

All I-50 adjustable arc rotors are preset to approximately 180°. Sprinklers can be adjusted with water on or off. 

  1. Use your hand to rotate the nozzle turret counterclockwise to the left stop to complete any interrupted rotation cycle.
  2. Next, 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. While holding the nozzle turret at the right stop, turn the arc adjustment ring counterclockwise to increase the arc.
  2. Adjust to any arc between 50° and 360°. The arc adjustment will stop turning when the maximum arc (360°) is reached. When set to 360°, the sprinkler will rotate continually counterclockwise at a rate of approximately 3 minutes per rotation (see Fig. 2).
To Decrease Arc
  1. If the arc is set to less than 360°, hold the nozzle turret at the right stop and turn the arc adjustment ring clockwise to decrease the arc.
  2. Adjust to any arc between 50° and 360°. The arc adjustment ring will stop turning when the minimum arc (50°) is reached.
