ABSTRACT:
A manually actuated adjusting device for control valves of a hydraulic lift mechanism of a vehicle, especially of a fork lift truck, includes a shifting lever with an armrest supporting a lower arm which is connected with an adjusting mechanism arranged below the same and consisting of a guide joint and support elements. A formed-out support surface extends over the entire length of the lower arm which terminates at one end in an approximately vertical shifting lever that is formed-in into the armrest. Within the area of its transition to the support surface, the latter includes a trough-shaped recess formed out of the plane of the support surface.
