Claim 6:
7. The interchangeable unit in combination with the road construction machine as recited in claim 6 further comprising:
a controller configured to:
switch the start-up clutch into a, or hold the start-up clutch in a, torque-transmitting connection state if the removal tool rotates at a speed that is lower than or equal to a first limit speed, the first limit speed being lower than a removal speed of the removal tool during normal removal operation of the removal tool;
switch a drive belt tensioner into an, or hold the drive belt tensioner in an, operating state such that a belt tension of the drive belt is at an idling tension when the removal tool rotates at a speed lower than a second limit speed, the idling tension being lower than an operating tension of the drive belt during normal removal operation of the removal tool, and the second limit speed being lower than or equal to the first limit speed; and
change the belt tension of the drive belt such that the belt tension of the belt drive is between the idling tension and the operating tension, the change in the tension of the drive belt corresponding to the change of the speed of the removal tool between the second limit speed and the removal speed.
