I have a new sprinkler system with HUNTER PCP sprinkler heads. Can some one help me? There are three holes on top of the sprinkler head. Two of the holes take the allen wrench side of the tool and one takes the butterfly side of the tool. I have three questions. 1) How do you control how far right or left the sprinler turns? 2) How do you increase or decrease the turning radius? 3)How do you adjust the length of the water stream? PLEASE HELP
