Claim 9:
10. A method of operating a machine according to claim 1, comprising the steps of:
setting the stabilizing unit down on the track via the vertical drive and actuated with a vertical load, and
driving said at least two rotatable imbalance masses by applying a variably adjustable second phase shift (Δφ1, Δφ2) to one another;
wherein one imbalance mass in an imbalance pair is driven right-turning and one imbalance mass is driven left-turning, and wherein at least one of these imbalance masses is driven applying a first phase shift (Δφ1) which is variably adjustable with respect to an initial position;
wherein in the case of four imbalance masses, two left-turning imbalance masses are driven applying a variably adjustable second phase shift (Δφ2) to one another and two right-turning imbalance masses are driven applying a variably adjustable second phase shift (Δφ2) to one another.
