The Weathermatic Turbo is a sprinkler head that uses a rotor to function and allows for adjustment to increase or decrease the arc of the water. You can make this adjustment from the top of the sprinkler head without removing the whole unit from the ground.
Grip the Weathermatic Turbo by the head of the unit. Turn the head clockwise to enlarge the arc of the water.
Turn on your sprinkler and test the arc. If you feel you need to readjust the arc, turn off the sprinkler.
Grip the sprinkler head, and twist it counterclockwise. Turn one the sprinkler again, and verify that the arc is how you would like it. Continue to adjust the sprinkler head until you get the arc the way you would like it.
