• Turn carefully, maximal one rotation anticlockwise, the emergency-lowering screw
N1 with a suitable tool (hexagon spanner 5). The lowering of one platform starts.
Lower the platform approx. 5- 10 cm then close the emergency-lowering screw.
If the platform does not lower, the cylinder is locked. Repeat the process of
unlocking the cylinder.
• Repeat the procedure with the set screw N2.
Repeat this alternate with the set screws N1 and N2 until the lift has reached his
lowest position.
• If the lift is in the lowest position turn the set screws clockwise and safe it with the
locknuts.
• Remove the hand pump and the objects between the cylinder and the flange!
The complete process must be observed by the operator. Close the emergency
lowering screws when any danger appears. After finishing the emergency
lowering, the set screws and the locknuts must be brought back into the original
position, otherwise a malfunction of the lift may occur.
Do not use the lift until defective parts are exchanged!!
Before the initiation after an emergency lowering, the objects between the cylinder
and the flange have to be removed! Otherwise the security devices are out of
function and this means danger to life and danger of damages!
6.2.2 Preparation for the emergency lowering (wheel free lift)
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. The
double seat valves SV1, SV2, SV3 and SV4 have to be kept pressed manually (see
pic. 5, pos. X) Further persons can make this action easier. Approximately 100 bar
are needed to raise the wheel free lift 10 mm.
