It can be tricky for the layperson to make rotor adjustments. The most important thing in adjusting any rotor is to set the fixed side of the rotor FIRST. (with the RB 5000, the fixed side is the left stop) You may need a set of Channel Locks to turn the head to adjust the left stop. Once you're satisfied with where it stops on the left, THEN adjust the right side with the arc adjustment screw.

One thing I noticed in the instructions after reviewing again.

They imply the water should be shutoff. Hence why they say "Pull up turret". FYI. I noticed the tech didn't shutoff the water first, but he's knows what he's doing.

Anyway, I think I could get a better grip if it's dry.

I'll call back my tech if all else fails.

thanks,

these heads have a left set area, in other words you have a set left sweep, you have this set then you adjust the right sweep with the screw

I found the easiest way to adjust the left stop is to loosen the big nut (just a fraction of a turn) first. Then the shaft can be easily turned by hand. I wouldn't recommend using channel locks - it will easily damage the plastic shaft preventing proper pop up/down action.
