I shut off the power to the boiler and took the cover off the relay box so I could turn the hi temp limit which is set at 190 down to about 160.
Here is a picture of the limiter:

I can't seem to move the pointer off 190. Do I push the dial down away from the pointer and then turn the dial to the new setting or do I somehow pull the pointer away from the dial and turn the pointer. I don't want to break anything but I can't get these 2 pieces apart from each other. Any advice?
