Claim 7:
8. The method according to claim 1, wherein, in a switching position, in which an operating-mode setting device is on “rearward delivering of construction material”, pressure changes detected by the at least one pressure sensor up to a limit value are ignored by the control device, and in that, in said switching position of the operating-mode setting device, the drive unit, with an actual pressure lying below the limit value, is operated in a reverse direction of rotation at a constant rotational speed or a constant torque which is greater than 0% and at most 50% of a rotational speed with which the drive unit operates in a normal mode, and, in said switching position of the operating-mode setting device, the drive is switched off when an actual pressure reaches the limit value.
