6.  Set the tool on the cartridge.  Fit the ears on the tool between the ears of the cartridge.
7. By hand, screw the knurled screw down into the cartridge stem.  Turn it until it stops.
8. Screw the hex nut down until it stops on the valve.
9. Twist handle by hand.  Try to turn and rotate the cartridge body.  If it still will not pull, then proceed as in Step 10.
