How to Set the Sprinkler Heads
- 1). Set the rotor sprinkler head start position. Rotate the rotor nozzle turret counterclockwise with your hand until it stops, then rotate the nozzle turret the other way to the left until it stops. This will set the sprinkler start position and complete any interrupted rotation cycles. The sprinkler will spray clockwise from the start position.
- 2). Insert the manufacturer's arc adjustment key into the adjustment socket at the center of your rotor nozzle turret. The arc adjustment key comes with the rotor sprinkler head package. Turn the key clockwise while holding the nozzle turret so that the turret does not rotate to increase the sprinkler arc or rotation angle. Usually, a full 360 degrees turn of the key increases the rotation arc by 90 degrees.
- 3). Turn the key counter-clockwise while holding the turret to decrease the angle of rotation. It is recommended that you adjust the arc until the arc indication arrow points to an angle between 40 degrees and 360 degrees. Avoid going beyond the 360 degree mark or below the 30 degree arc setting.
- 4). Fine tune your sprinkler head settings. Supply water to the sprinkler installation. Increase or decrease the radius of spray as desired by adjusting the indication arrow setting from the arc adjusting key.
