Unscrew the main bolt from under the forefoot. That will show you the strap to change the boot sole length. Set it to the nearest length to your size (The heel moves back and forth). Then click in your boot.
The forward pressure screw is the lowest on the heel. That should be flush to the housing.
If it is not, TAKE THE BOOT OUT, and adjust it. Repeat putting the boot back in and adjusting as needed. (You might have to change the original length setting you chose to make it work too.
BEWARE: Not removing the boot when you adjust forward pressure can strip the track -- and guess what? Premature release, because you BROKE IT!
