<p>The machine has mobile housing (4) with upwardly running guide handle (7) which is connected via bearing (8) pivotably mounted on housing, and is stopped in different working positions (A-C) so that upper end is located at operator desired working height and is forwardly foldable in rest position. The pivot bearing has axially offset pivotal ranges for working positions and rest position. A clamping device alternatively blocks or releases pivotal ranges so that pivotal range for working positions is released before pivotal range for rest position upon release of clamping device.</p> |
