There is an adjustment hole that you stick on of the Allen wrenches in, lock the BrakeAway, slightly loosen the two small Allen screws then, by using the Allen wrench as a lever loosen the BrakeAway so that it will just hold the throttle in place.
Section 4 of the manual does a better job of describing this than I can:
