If any binding occurs, loosen the limiting nut and turn the adjustment knob until it moves freely. Then 
retighten the limiting nut.

12

Rotate the adjustment knob a full turn counterclockwise from its full clockwise position. This should turn the 
pressure ON. 

13

Pressurize the chamber and check the entire assembly for leaks.
