CMP Powerclean Chlorinator Issue

[TDragger]

I have looked online and in my documentation to see if there is a way to lube the flow adjustment dial. This is my first season using it and its stiff as heck. I'm afraid it could snap off, its that stiff.

Ideas?

Thx

If you pull the knob's cap off, there's a phillip's screw. I've not taken it down, but would make sense that the screw holds the valve in. There's no other entry for it to the canister.
