Emergency lowering at power failure:
Power failure and a vehicle is still on the lift:
Switch off at the main switch and secure it against switching on again.
Remove protective covers from the column heads.
Insert a suitable key into each of the crown nuts on the upper end of the lifting spindle.
By turning the two lifting spindles simultaneously and evenly the vehicle can be moved slowly downwards.
If movement is sluggish because of damage to the motor bearings:
Before turning the spindles, loosen the ribbed V-belt on the motor drive activators.
Emergency lowering with the service plug:
When emergency lowering is carried out with the service plug it must be taken into account that the switch
box at the control columns must be opened for this purpose and that touching of live parts is dangerous.
The power supply must be switched off, the hood on the control side must be pushed upwards and secured
against sliding down. The switch box is then opened, the power supply can be connected again and the
work process can be carried out as follows:
1. Press H-mode (Help mode key), signal initiator sends out a bleep.
2. Insert the service plug on the electronic board (10-pole box socket).
3. LED is switched off
4. Press H-mode key -> LED turns orange.
By pressing the “down” key both columns can be moved down.
It must be checked that both lifting carriages are descending simultaneously and evenly. If faults in the
movement are noticed, the lowering process must be stopped immediately. The stipulated working process
must be adhered to, since faulty handling can change the control mode and a function is called up.
Next, the main switch of the lift should be set up to “0” position and be secured against switching on.
The customer service must be informed.
Driving against an obstacle:
If the lifting carriage or the lifting arm drives against an obstacle through carelessness of the operating
personal, only the motor blocks, of which lifting carriage or lifting arm stands on the obstacle. The 2 post lift
disconnect, as soon as the other lifting carriage drives through the range of control of about 40 mm. As an
extra protective arrangement are at the motor windings temperature probes installed, which disconnect
control current by overload motors. An further servicing of the 2 post lift is possible after ca. 10 minutes later
(wait for the cooling of the electro motor). After blocking from the motor the belt has to be checked for
possible damage and may be changed by another. Please contact your service-partner (dealer).
