6.2 Emergency lowering
A emergency lowering is an intervention into the control of the lift and can be done
only by experienced expert.
The emergency lowering must be carried in this order. Otherwise a malfunction can
lead it to damages or lead to danger for body and lives.
Every kind of external leakage has to be removed. This is necessary in particular
before an emergency lowering.
The emergency lowering may only be done by persons which are trained in using the
lift.
Reasons, that can make an emergency lowering necessary, are a defect of the electric system
or disturbances of the valves, etc.
In case of power-failure or defective Valves there is the possibility through suitable tools to
lower the lift in the lowest position, so that the vehicle can be driven off.
6.2.1 Procedure of the emergency lowering

The piston rod can be stuck through the dirty deposit at the
top of the hole. Use the solvent and lubricating stuff (for an
example WD40) to loosen the connection. The WD40 is
sprayed generously between the screw thread and the bore
hole (see arrow). The time of the effect follows the
contamination-degree.
