what year are you pilots? there are at least two diffrent types these bindings. The older style 912/914 have both a toe screw adjustment and a heel tab w/forward pressure indicator. basically you adjust the toe and heel in order to center the boot over the center of the ski (one advantage is you can easily move yourself fore or aft of center if prefered). the 8 seires pilot bindings don't have the toe screw. Newer pilots use a pre-drilled plate with boot sole length ranges marked on them. Proper forward pressure is indicated (with the boot locked in the binding) when the arrows on the rear adjustment tab line up with the machined recessed area on the heel. The toe wings and 0.5mm AFD clearance must also be adjusted. If in doubt, as always have you gear adjusted by a certified tech.
