Ryobi 40V trimmer won't stop Some water spray while locating and clearing sprinkler heads started the problem. All dried out, but problem remains.

SOURCE: Hunter sprinkler head adjusting...

I googled Hunter sprinkler heads and where to purchase them. In my area (the East bay, Tri-Valley) in Nothern California.

I went to Ewing Irrigation in Dublin, CA and found the Hunter sprinkler heads there. The man working the counter got two for me and he demonstrated how to change the head by unscrewing it from the base at or just below ground level by removing the old one and screwing in the new head. He also showed me how to adjust them with the spray pattern. You will need the little tool that comes with the sprayer head.

Making sure the center arrow is completely to the left and rotate the head to the right then back to left. They are set to a 180% spray pattern from the manufacturer. If you want a bigger pattern you turn the adjuster toward the ( + ) side and if you want less pattern you turn the adjuster to the ( - ) side. He showed me how to install the red sprayer inserts by simply pushing them in the cavity making sure the little u shaped indentation is pointing up to allow for the set screw to go through to adjust the spary.The spray varies in distance and amount of water being emitted from the head depending upon the insert used.

I was able to replace the Hunter head, adjust the spray and changed out the insert a few times until I found the one I liked. I used needle nose pliers to remove the initial spray insert that the man @ Ewing installed until I found the one that worked best.

I found using needle nose pliers makes it very easy to grasp the little inserts for replacing.

SOURCE: Replacing the cutting head on Ryobi string trimmer.

There is a nut above the head, place a wrench on the nut then unscrew the head from the shaft, unless yours is different from mine this is how it works. I hope this helps.

SOURCE: I cannot remove the head

Being new, I'd return it if the the head flew off. When you say head I see the Engine head coming off and the engine be a total mess. What part are you actually talking about. Is it plastic or aluminum? Here is a link to PDF doc that you can download. If your talking about the part with the string that cuts, which I think you are, you need to screw it back on and make sure you have a something that is locking the screw in place while you screw it down. You can use the special tool that should have been included with the weed eater or use a Phillips head screwdriver in the locking hole to hold that mounting bolt steady for you. I found a pretty good picture of the process in the manual I found here :

Hi and wel;come to FixYa, I am Kelly.

Your problem is caused by either drive shaft failure or.. clutch failure. Most of the time the drive shaft fails before the clutch.
