4.Safety regulations
If you use the automotive lift, the German following regulations are to be considered:
BGG945: Examine of automotive-lifts; BGR500 Using automotive-lifts; (VBG14).
Especially the following regulations are very important:
• The laden weight of the lifted vehicle must not exceed 6000 kg for the automotive lift.
• The automotive lift must be in its lowest position (fully collapsed), before the vehicle can
be driving on to the lift. Only then can the vehicle be lifted.
• While working with the lift the operating instructions must be followed.
• Vehicles with low clearance or vehicles that are specially equipped should be pre tested
to ensure that they clear the lift ramp to avoid damage.
• Only trained personnel over the age of 18 years old are to operate this lift.
• No one is to stand within the working area (danger area) during lifting and lowering
• No one is to be raised or lowed either directly or in a vehicle by the automotive lift.
• No one is to climb onto the automotive lift or onto an already raised vehicle.
• The automotive column lift must be checked by an expert after changes in the
construction have been made.
• The main switch must be switched off and locked before work on the vehicle can commence. This
is a safety precaution to ensure that the lift does not move during work.
• The main switch must be switched off and locked before any maintenance or repair work
on the automotive lift itself can be carried out.
• During lifting or lowering the operator must observe the vehicle to ensure that the vehicle
and the lift are functioning correctly.
• Installation of the standard-mobile column lift in hazardous or dangerous locations such
as washing bays is dangerous and is not allowed.
• Check the centre of gravity of the vehicle if heavy parts (egg the motor) are removed.
• If heavy parts must be removed (motor) the centre of gravity will change. Secure the
vehicle before removing parts to avoid the possibility of the vehicle becoming insecure.
• The capacity is reduced to max. 4200 kg when using the forklift adapters.

5.Operating Instructions
The Safety Regulations must be observed and adhered to while working with the
automotive lift. Read the safety regulations in chapter 4 carefully before working with
the lift!
5.1 Lifting the vehicle
• Drive the vehicle onto the middle of the lift.
• Secure the vehicle from rolling, put into gear, apply the hand brake.
• Before positioning the arms under the vehicle, press the button; “unlocking the arms” and
the pneumatic safety device will open.
Slew the carrying arms under the vehicle and position the pads at the points specified by
the vehicle-manufacturer. The arms will lock, if the button “lifting” is pressed.
• Determine the centre of gravity. This point must be located in the middle of the lift. If
necessary, adjust the lifting-pads until the vehicle is in the raising condition, that is
horizontally level.
Pic 1:
• Check all the danger points of the lift and ensure that there are no objects or people in
the working area around the lift or on the lift.
• Switch on the main switch.
• Raise the vehicle. Press the button “lifting” until the wheels are free. If the wheels are
free, stop the lifting procedure and check the safety position of the vehicle on the pads
again. Check also the locking system of the arms. They must be locked, if the wheels are
free. Otherwise lower the lift and position the vehicle one more time.
Closely observe how the vehicle is positioned on the lifting pads. If the vehicle is not
correctly positioned on the pads the vehicle is not secure and the risk exists that the
vehicle may fall.
• Raise the vehicle to the required working height. Press the button “lifting”.
• Observe the complete process.

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.

6.2 Emergency lowering
A emergency lowering is an intervention into the controls of the lift and can be done
only by experienced expert.
The emergency lowering must be carried in this order. Otherwise a malfunction may
lead to damage to equipment, injury or even death.
Every kind of external leakage must be removed. This is particularly necessary before
an emergency lowering.
The emergency lowering may only be done by persons who are trained in using the
lift.
Reasons, that may warrant an emergency lowering are; a defect in the electric system or
disturbances of the valves, etc.
In case of power-failure or defective valves it is the possible through the use of suitable tools to
lower the lift to its lowest position so that the vehicle can be driven off.
