Description
The Saturn IV and Voyager II gear-drive rotor sprinkler adjustment key is engineered for adjusting the arc and radius, as well as for raising the riser stem when the water is off. The tool consists of a 3/32 Allen key for adjusting the radius, two finger loops for gripping, and an arc adjustment key. In a pinch you can also use a 3/32 Allen key for radius adjustment only.
To adjust the arc, insert the plastic tee side of tool into the circle with the +/- and rotate clockwise to increase the arc and counterclockwise to decrease it. Note that the right side is fixed, so the adjustments will increase or decrease the left stop. To adjust the radius, put the Allen key into the arrow and turn clockwise to decrease the radius and counterclockwise to increase it. To raise the riser stem when the water is off, insert the plastic tee side of the tool into the rectangular slot, turn 90 degrees, and lift.
The Saturn III® and Voyager adjust with a standard slotted screwdriver and do not require a key. Compatible with Orbit, Hydro-Rain and Hunter gear-drive rotors. For outdoor irrigation use with cold water only.
