(5)With the vacuum pump still running, close the “Lo” knob of the manifold valve. Then stop the vacuum pump.

(6)With the accessory hex wrench, turn the valve stem on the narrow tube service valve counter-clockwise by 90 degrees (1/4 turn) for 10 seconds, and then turn the stem clockwise to close it again. (Fig. 58)

the hex wrench before

 

 

attempting to turn the valve.
