Question
I have several new Toro Prostream XL Rotor Sprinkler heads I can adjust the Arc to cover but do not know how to set where the Arc starts from.  One Head by house - I need 90 degrees travel - which I can set - but all of the 90 degrees of travel is all pointing at and along the house - How do I reset where the travel starts from ?

Thanks

Answer
Hey Forrest, you need to turn the entire head to the position you want it to start from, there is no way to reset the starting point, it is already set. On the bottom of the head is a threaded fitting that when you turn the head either clockwise or counter clockwise will pivot and not damage the pipe below. Simply grab the body of the head (below the top cap) and turn the head one way or the other, until you get it in the position you want it to throw. good luck and have a great day.
