5.2 Lowering the vehicle
• Check all danger points of the lift and be sure that there are no objects or people in the
working area (danger area) around the lift or on the lift.
• Lower the lift to the required working height or to its lowest (or fully collapsed) position.
Press the button “lowering“. The lift will rise approx. 1 mm (safety function) before it
starts to lower.
• Before the lift reaches its lowest position, the lift stops automatically (CE-Stop). After the
lift has stopped, check the danger areas around the lift. Press the button “lowering” again.
A warning signal will sound as the lift is further lowered. This is to warn against the risk of
crushing as the lift is lowered to its lowest (fully collapsed) position.
• Observe the complete lowering process.
• Once the arms are in the lowest position, press the button “unlocking the arms” and
remove the arms from under the vehicle.
• Drive the vehicle off the lift.
5.3 Position measurement
An hall sensor on the hydraulic cylinder monitors the threaded spindle by counting the
magnetised increments on the outer ring.
The number of increments counted is transmitted to the Controller. The controller processes
this information and regulates both lifting carriages so that they remain level. The current
position is shown on the Display.
• The SST (Safety-Star Technology) observes the complete Process of the Lift during “Lifting”
and “Lowering”.
• The automotive lift lowers with a average load at a rate of 0.05 Meters per sec.
If the lift descends noticeable faster there may be a problem with the hydraulic
system. The computer-control-system recognizes the problem and switches off the
hydraulic supply for the cylinder. The Safety-star system locks and the lift stops.
5.4 Manual equalization of the automotive lift
Only trained and authorized staff are allowed to work with the DIP-switches! The main-
switch must be switched off!
• If the Computer Control System recognize a difference of approx. 40 mm between both
lifting carriages, it will stop the lift automatically.
• Equalize the lifting carriages.
• Open the electrical box.
• Adjust the following Dip-switch as described: (see Pic. Pos. K)
Dip switch 5 (regulation ON/OFF).
Dip-switch 1 (only lifting carriage 1 moveable).
Dip-switch 2 (only lifting carriage 2 moveable).
Dip-switch 7 (reset – zero the lift in the lowest position).
Enforce the equalisation:
• Equalize lifting carriage 1.
• Move the Dip Switch 5 to the “off” position (regulation off).
• Move the Dip switch 1 to the “on” Position (Dip switch 1 for platform 1).
• Press the button “lifting” or “lowering” and the override switch simultaneously until the
platform is level.
• Move the Dip switch 1 to the “off” Position.
