5. Operating instructions
The Safety Regulations must be observed during working with the automotive lift.
Read the safety regulations in chapter 4 carefully before working with the lift!
5.1 Lifting the vehicle
• Drive vehicle over the lift, longitudinal axes on line of the lift.
• Block the vehicle against rolling, put into gear.
• Check the dangerous places of the lift and be sure that there are no objects or
people in the immediate area of the lift or on the lift.
• Switch on the control system; main switch on position ”1” (see pic.1)
• Raise the lift. Press the button „lifting“.
• Lift the vehicle on the working height
• In the display of the operating unit, the momentary height of the platform can be
read.
• Observe the complete process.

5.2 Lowering the vehicle
• Check the dangerous places of the lift and be sure that there are no objects or
people in the immediate area of the lift or on the lift.
• Lower the vehicle to the working height or until the platform reaches the lowest
point; press the button „lowering“ .
The lift is raising a few millimetre before the lift lowered (the safety device is
unlocking).
• Observe the complete process.
The lift stops before reaching the lowest position CE-Stop).

Control the dangerous places of the lift and be sure that there are no objects or
people in the immediate area of the lift or on the lift. Press the button
“Lowering” until the lift again. You hear an acoustic signal until the lift is
reaching the lowest position.
• Drive the vehicle out of the lift if the lift is in the lowest position.
5.3 Equalisation of the Lift
• Press the button „Equalization the platform“ at the operation unit. The Platform of
the lift equalize.
5.4 Function Microprocessor / Display-advertisement
• The automotive lift is equipped with a microprocessor. This system recognizes an
unequal of the lift and regulate the hydraulic valves until the lift has the same
height.
• The processor recognizes the present position of the cylinder. The lift switched off
if the automotive lift reaches the top end position or the bottom end position or the
position of the CE-Stop.
• The display shows the present position of the cylinder.
• this display is required also for the service-business, over a foil-keyboard.
5.5 The lift is not in the rule-window
• The lift switched off, if the lift is not in the rule-window of ± 50 mm.
• Read the chapter 5.6 step B to put the lift in the normal Function.
5.6 Function of the bypass-switch in case of unequal level of the platform
Pic 2: Position of the bypass switch
A) Do not press the button „lifting“ shortly consecutively before the lift was lowered 50
mm. Otherwise the lift will raising over the top limit position. After, it is not possible
to lower the lift again with the button „lowering“.

B) In this case it is possible to lower the lift with the button „lowering and the bypass
switch. Press both buttons simultaneously (see pic 2, arrow) until the lift has the
normal function again.
Take careful, otherwise a malfunction can occur.
6.Troubleshooting
If the lift does not work properly, the reason for this might be quite simple. Please check
the lift for the potential reasons mentioned on the following pages. If the cause of
trouble cannot be found, please call the technical service
Problem: Motor does not start!
Potential causes: solution:
- no power supply Check the power supply
- main switch is not engaged Check the main switch
- fuse defective Check the fuse
- the feed line is cut Check the feed line
- Button „lifting“ defective Check the button
- Thermo fuse active Let it cool down
- Out of the rule-window ± 50 mm Read chapter 5.5
Problem: Motor starts, lift does not lifting!
Potential causes: solution:
- The vehicle is too heavy Unload the vehicle
- Level of the oil is too low Fill in new hydraulic oil
- The hydraulic valve is defective Call the lift service
Problem: The lift does not lowered!
Potential causes: solution:
- The lift is standing on a obstacle Read chapter 6.1
- The hydraulic valve is defective Call the lift service
- fuse defective Check the fuse
- button „lowering“ is not pressed or defective Check the button
- the holding valve is defective Call the lift service
- the safety device is locked Call the lift service
6.1 Driving on an obstacle
If the Safety-Star-System recognizes a difference of ± 50 mm between the platforms
then it switches off the lift.

- 19 -
6.1.1 Remove an obstacle
Only trained and authorized staff is allowed to work with the DIP-switches! The
main-switch has to be switched off!
• Remove the cover of the operating unit and the control box.
• Press the button “lifting” and the bypass switch simultaneously. (pic 3, arrow).
Raise the lift until the object can be removed.
After it, lower the lift in the lowest position and enforce a reset.
Take careful, otherwise a malfunction can occur.
6.2 Emergency lowering
A emergency lowering is an intervention into the control of the lift and can be
done only by experienced expert.
The emergency lowering must be carried in this order. Otherwise a malfunction
can lead it to damages or lead to danger for body and lives.
Every kind of external leakage has to be removed. This is necessary in particular
before an emergency lowering.
The emergency lowering may only be done by persons which are trained in using
the lift.
Reasons, that can make an emergency lowering necessary, are a defect of the electric
system or disturbances of the valves, etc.
In case of power-failure or defective Valves there is the possibility through suitable
tools to lower the lift in the lowest position, so that the vehicle can be driven off.
6.2.1 Procedure of the emergency lowering
• Switch off the main switch an d safe it. (lock it)
• Remove the covers of hydraulic unit.
• Secure the dangerous place around the lift.
Pic 6:
Loosen and remove the 2 lock nuts with a suitable
tool in arrow direction. Carry out this process at
both columns. (Key 41)

Pic 7:
The piston rod can be stuck through the dirty
deposit at the top of the hole. Use the solvent and
lubricating stuff (for an example WD40) to
loosen the connection. The WD40 is sprayed
generously between the screw thread and the
bore hole (see arrow). The time of the effect
follows the contamination-degree.
Pic 8:
Loosen the cap of the Minimess connection and the
cap of the tank. Fasten the Minimess hydraulic tube
at the screw fitting and put the other end into the
tank.
Pic 9:
Use the long screw thread-bushing and
turns with a suitable tool (key-wideness 24,
available with your dealer,), clockwise.
Lower the lifting carriage only approx. 5cm
– 10 cm. Repeat the process at the next
column. Lower always 5 cm-10 cm until all
lift are in the lowest position.
Repair the defective lift. After it create a
Reset which is described in the operating
instruction.
Attention!! Lower the automotive-lift only approx. 5cm – 10 cm.
Observe the complete emergency lowering process.
Do not work with the lift until the defective parts are changed.
