Hayward Chlorinator CL100/CL110 drip help!

I was cleaning the pool a few days ago and noticed I needed to adjust the chlorine feeder to a higher level. I turned it up and noticed a drip drip drip out of where the control knob goes into the feeder. I turned it back and forth a few times and the drip got worse, now a steady stream. I headed for the pool store and they do not stock a new control knob but suggested I unscrew the control knob and put some teflon tape on the threads... Well, it did not unscrew (it just turns from off to 1/8 1/4 1/2 3/4 full), smoothly but then hits a stop. I came home got on the computer and discovered that all I needed was two o-rings and I could put them on the control knob shaft or I could purchase a new control knob for somewhere between $11 and $30 plus shipping. But nowhere online could I find how to remove and replace the control knob. Unfortunately it is near the ground and faces away from me.

The feeder is a Hayward CL100/CL110,(no check mark on the feeder to say which one) it is a inline feeder and takes the CLX100FA Control Knob. The knob is plastic and in a poor location and pulling and prying not knowing how it comes off could only break it off or break the Chlorinator. The Chlorinator has been working fine for the last 5 years and it was here when we bought the house. I've spent quite a bit of time online and have downloaded several (5) PDF's nice drawings but no info on removing the knob and I have google searched 4 hours unable to find out how to remove the knob. The Hayward FAQ's did not list my problem.

Any help will be greatly appreciated.

Thanks,'
Have a great day.

If anyone knows how to remove and replace the knob please post here.

Can anybody help this poster?

I'm sorry I missed this post. When you don't get an answer in a couple days just make another post to bump it to the top of the list.

Welcome to the forum. I have one of those and the knob is a dog. I cut off the tab that stops it from turning so I can unscrew it all the way. I've had to replace those O-rings every couple years but I use the Home Depot flavor that aren't that resistant to chlorine. Cents vs. dollars apiece. I think you're supposed to be able to squeeze the knob to get the tang past the stops but not sure. Been many years since I cut the tang off. Once you unscrew it the repair is obvious.

Again, sorry for missing this.

Edit: Found this in the CL-100 guide.
"To remove dial valve handle.
Set pointer to Full. Insert screwdriver in slot opposite pointer, lift up and rotate handle counterclockwise. This allows the handle index lock tab to clear the body ridge."
