Hi, I'm new to this watering world and would appreciate any advice. System is rather recent and so far no problems. I have a couple of Hunter pop up heads that I'd like to adjust (they're overshooting the desired area). I just got the adjusting tool but no instructions. Any special procedure? Does Hunter have any pamphlet/booklet out that covers operation/maintenance for the overall system? (winterizing/spring startup). Thanks for any help you can offer.
