Adjusting A Rain Bird Rotor Head
In this article we will discuss the basics on how to adjust a Rain Bird Rotor, so your lawn will be happy and you’ll avoid wasting water.
Proper lawn maintenance requires a sprinkler system in tip-top condition. And a primary component of sprinkler system maintenance is keeping your rotors adjusted. Your rotors should be delivering head-to-head coverage. And also minimize the amount of water hitting sidewalks, streets or other hard surfaces.
Arc Adjustments for Rain Bird Rotors
Align Fixed LEFT Edge:
- Pull up turret and turn to the left trip point (counterclockwise). CAUTION: If while adjusting the rotor, it does not turn easily to the left, first turn it right (clockwise) to the right trip point.
- Rotate entire case to the desired fixed left position, OR unscrew cap and pull out assembly. Rotate internals to re-align left trip point to the desired adjustment point and re-install.
To Increase Or Decrease The Arc:
- While holding the nozzle turret at the fixed LEFT stop, insert tool or screwdriver into the adjustment socket.
- Next, adjust the arc with a screwdriver:
- Turn the screwdriver clockwise, (+) to INCREASE arc.
- Turn the screwdriver counterclockwise, (-) to DECREASE arc.
- Each full clockwise turn of the screwdriver will add or remove 90 degrees of arc.
- When the maximum arc of 360 degrees or minimum arc of 40 degrees has been set, you will hear a ratcheting noise. Do not adjust the rotor beyond the maximum or minimum arc.
Rotor Radius Adjustment:
- Insert a screwdriver into the radius adjustment socket of the rotor.
- Turn the screwdriver clockwise to reduce radius, and counterclockwise to increase the radius.
