Reasons, that can make an emergency lowering necessary, are e.g. a defect of the
electric system or disturbances of the valves, etc.
In the case of
power failure
, the emergency-lowering can only be done if the
automotive-lift is not blocked in a safety device. If the lift is locked, the command valve
cannot be opened and the security system cannot opened. Wait for the end of the
blackout in this case.
In the case of
defective electromagnetic valves
, the hydraulic valves of the lift will not
open any more. Therefore the lift can not be lowered. In this case there is the possibility
to open the hydraulic valves manually and to lower the lift into its lowest position, so
that the vehicle can be driven off.
Preparation to the emergency lowering
1. Switch off the main switch and safe it. (lock it)
The emergency lowering can only be performed when the interactive Safety-Star-
System is not locked.
2. To execute an emergency lowering, the interactive security system has to be opened.
Connect a hand pump with the measuring connection M3 at the hydraulic bloc.
Approximately 100 bar are needed to raise the lift 10 mm.
3. Unlock the security system manually in the direction of the arrow. (see pic. 4).
Put a suitable object (e.g. metal disc) between the cylinder and the flange.
(see pic. 4, white arrow)
4. Repeat this measure with the other cylinder.

Procedure of the emergency lowering (main lift)
