<p>The machine (F) has a screed (9) including a hydraulically movable extendable screed part (10), and a control panel (27) having a control that is manually operable by an operator. The control includes a rotary knob (16) that is manually movable between a zero position and a maximum position to produce an increase in kinetic resistance noticeable by the operator, the increased kinetic resistance noticeably signals either a predetermined speed or a transition between two different speeds of a movement actuator (11) of the extendable screed part.</p> |
