To lower the lift the control valve MV2 (m) on the aggregate has to be opened.
Therefore the unit cover has to be removed. The control valve MV2 is the left one of the two
valves. Again, first the black cap has to be removed and then the screw-on cap with the Allen
screw (f) is fastened.
By tightening the Allen screw the valve MV2 is opening and the lift begins to lower. The low-
ering speed can be controlled by adjusting the Allen screw.
In case of danger stop the lowering operation by closing the valve MV2.
