6. Inspection and Maintenance
Before conducting maintenance work, preparations must be made to ensure

that during maintenance and repair work there is no risk to the safety of
people working on or around the lift and also that there is no risk of damage to
equipment being used on or around the lift.
To guarantee the utmost availability and to ensure that the lift remains functional,
maintenance work contracts are organised between our clients and their local retailers.
A service must be performed at regular intervals of 3 months through the operator in
accordance with following service manual. If the lift is in continuous operation or in a
dirty environment, the maintenance rate must be increased.
During daily operation the lift must be closely observed to ensure that it is functioning
correctly. In the case of malfunction or leakage the technical service must be informed.
6.1 Maintenance plan of the lift

• Before beginning any maintenance work isolate the power supply. Secure the
main switch (lock it). Secure the danger area around the automotive lift and
secure the lift against unintentional lowering
d,e,f clean and grease the pull-outs of the carrying arms, bolts of the pads and slide
ways of the carriage sliding blocks.
b Oiling the spindle and the lubricating felt between the carrying nut and the
centring of the spindle one time a month with a thin oil as SAE15W40.
Attaching twice lifting and lowering the lift in the end position. After lifting
and lowering the lift with load.
The lubricating interval has to be carried out at every maintenance. If the lift is
in continuous operation, the maintenance rate has to be increased.
The nut between the column (c) and the covering (g) will greased with an oil
can.
The regular complete lubrication in the mentioned distances
secures the absolutely easy operation for the lift.
Pic. 8: lubrication plan
- 16 -
2.40 SL m.m.
Do not use an biodegradable adhesive oil for greasing the spindle.
A normal adhesive oil impaired the qualities of the lift. We recommend a thin
Oil: for an example SAE15W40.
A over-lubrication or greasing with grease of the spindle through a intensive
lubrication supplies reduce the degree of effectiveness of the lift.
f check the rubber pads, otherwise exchange it.

h grease sequence nut one time a month with multipurpose fat. Use boring at
lifting carriage. (remove the cover)
a grease the spindle bearing annually with multipurpose.
Clean the Mini-Max in regularly interval with air pressure. That is a reason-
prerequisite for a trouble-free function. In case of a strong contamination, a
cleaning is to be enforced. (See chapter 6.2 ).
Pic 9: Mini-Max carrying arm

After the cleaning, lubricate the surfaces (for example: the bolt) with a oil.
1 Blow out the Bolts with air

pressure.
Test the roll on wear.
2 Check the safety screw. (The
screw is only easily fastened and
additional fastened with a
adhesive => Loctite).
The screw cannot be put on
solidly, otherwise the smooth
running of the Mini-Max
mechanisms is no longer
guaranteed.
3 Clean the surface and spray it.
4 check the safety sheet
• The electric parts are to be tested for damages.

• Check all welded joints for cracks on the automotive-lift.
If any cracks are found on the lift cease use immediately. Switch-off and secure
the main switch (lock) and call the service partner.
• Check all surfaces and repair if necessary.
• Damage to external surfaces, must be immediately repaired.
If theses repairs are not made immediately, permanent damage to the powder-
coated surface may result.
Repair and clean damaged areas with an abrasive paper (grain 120). After this is
complete, use a suitable paint (observe the RAL Number).
• Check the zinc surface and repair it with a suitable tool. Use abrasive paper (grain
280).
- 17 -
2.40 SL m.m.
White rust can result from moisture laying in certain areas for long periods of
time. Poor aerating can also result in rust formation.
Rust may result from mechanical damage, wear, aggressive sediments (de-icing
salt, liquids) or insufficient cleaning.
Repair and clean these areas with abrasive paper (grain 280).
After this is complete, use a suitable paint (observe the RAL Number).
• Check all the safety devices of the lift.
• Check the welding of the lift.
• Check the turning moments of the screws.
6.2 Cleaning of the automotive lift
A regular and appropriate maintenance served the preservation of the lift.

It can be a prerequisite for claims at possible corrosion.
The best protection for the lift is the regular cleaning of dirt of all manner.
- Including this:
• de-icing salt
• sand, pebble stone, natural soil
• industrial dust of all manner
• water ; also in connection with other environmental influences
• aggressive deposit of all manner
• constant humidity by insufficient ventilation
How often must the lift be cleaned ?

This is dependent on the use, of the working with the lift, of the cleanness of the
workshop and location of the lift. The degree of the dirt is dependent on the season, of
the weather conditions and the ventilation of the workshop.
Under bad circumstances it is necessary to clean the lift every week, but a cleaning
every month can suffice.
- 18 -
2.40 SL m.m.
Clean the lift and the floor with a non-aggressive and non-abrasive detergent. Use
gentle detergent to clean the parts. Use an standard washing-up liquid and lukewarm
water.
- Do not use for cleaning a steam jet cleaning
- Remove all dirt careful with a sponge if necessary with a brush.
- Pay attention that are no remains of the washing-up liquids on the lift after cleaning.
- Do not use aggressive means for cleaning the workshop floor and the automotive lift.
- A permanent contact with every kind of liquid is forbidden. Do not use any high
pressure device for cleaning the lift.

7.1 Emergency lowering in case of power failure

In case of power failure the lift can not lowered with the motors. In this case there is the
possibility to lower the lift manually. Draw the main plug or switch off and lock the
main switch and remove the cover of the v-belt pulleys. For this the lift must be turned
down to lowest position at the nut on the top end of the spindle. If the lift is in the
lowest position removes the vehicle.
The emergency lowering must only carried out by persons which are
instructed to using the lift. Please refer to the regulation “Lowering the
vehicle”.
Procedure – emergency lowering

• loose the main plug; switch off the main switch and lock it.
• remove the cover of the v-belt pulleys.
• lower the lift: turn the nuts (every side) alternately 5 cm until the lift has reached
lowest position.
• after the emergency lowering: Do not work with the lift until the faulty parts are
exchanged.
7.2 Driving onto an obstacle
If the lifting arm or the lifting carriage is driven on a obstacle, the motor from this side
locked. The lift switched off if the lifting carriage are not more in the regulation range
(approx. 64 mm).
An additional protection is a temperature control in the motor. Which interrupt the
electrical circuit when it is overloaded. You can not work with the lift. Cool down
approx. 5 – 10 min. dependently on the outside temperature.
After the locking of the motor check the V-belt if necessary replace it. Call the service-
partner.
7.3 Function of safety device
The lift is equipped with a safety switching, which controls the wear of the main nut.
If the lifting nut is broken, a safety nut which is conducted loose in the spindle, carries
the load. After a break of the nut, the lift can only once being lowered in the lowest
position. If the lift has reached the lowest position it is not possible to raise the lift.

other side is driving out of the regulation range and switched off the lift. You can not
work with the lift anymore. Call the service-partner.
If the safety device is active call the service partner!
Switch off the main switch at all repairs and disturbances!
The electrical system may only be opened by trained persons!
7.4 Manually equalisation of the carriage
The lift is equipped with a position measuring system which guarantee the
synchronisation of the lift. The electrical control recognizes if one lifting carriage is
approx. 18 mm earlier at the definite height. The electrical control stopped the motor of
this carriage until both carriage have the same height again. After it both motors are
working together again.
If the carriages of the lift are driving out of the regulation range/switching off window
of approx. 64 mm, the electrical control recognizes this and
switched off the lift.
To reach the normal function of the lift you must equal manually the carriages. Remove
the cover of the V-Belt pulley at the top of the lift. Equal the lift: turn one nut until the
carriage have the same height.
7.5 Adjusting of the top limit switch and the bottom limit switch
The operating unit of the lift is equipped with potentiometer. One is for the top limit
switch and one is for the bottom limit switch. The Potentiometer may from safety
reasons being only adjusted by trained person.
Out of safety reasons: The Potentiometer only may be adjusted by competent trained
persons.
• Pull the main plug before the maintenance or repair.

It is possible if the adjustments are wrong that the lift has malfunctions. It is
danger for your life for the lift and the vehicle.
• Loose the screws of the operating unit. Pull it careful out of the column. (pic. G)
• If the Potentiometer 3 (top-limit) is turned anticlockwise, the upper end-point has
been moved up. The lift stops later.
• If the Potentiometer 3 (top-limit) is turned clockwise, the upper end-point has been
moved down. The lift stops earlier.
• If the Potentiometer 4 (bottom-limit) is turned anticlockwise, the lower end-point has

been moved up. The lift stops earlier.
• If the Potentiometer 4 (bottom-limit) is turned clockwise, the lower end-point has
been moved down. The lift stops later.
After the adjusting do not lifting or lowering to the end position. The lift can
lock or jamming!
Alter the potentiometer easily. After it operate the lift. Repeat the process
until the normal end position is reached.
• Pay attention at the cover and the rubber behind the operating unit. Do not damaging
this parts. If the parts are faulty replace it. Otherwise the protection (IP54) against
liquids is no more ensured.
8. Installation and Initiation
8.1 Regulations for the installation
• The installation of the lift is performed by trained technicians of the manufacturer or

its distribution partner. If the operator can provide trained mechanics, he can
install the lift by himself. The installation has to be done according to this regulation.
• The standard lift must not be installed in hazardous locations or washing areas.
• Before installation a sufficient foundation must be proved or constructed.
• An even installation place has to be provided. The foundations must be based in a
frost resistance depth, both outside and indoors, where you must reckon with frost.
• An electrical supply 3~/N+PE, 400 V, 50 Hz has to be provided. The supply line
must be protected with 16A T (VDE0100 German regulation). The minimum
diameter amounts to 2,5 mm².
• The cable entry in the column is located in operating column topside. Another
possibility is the location of the cable entry in a boring at the base plate. However the
cable has to be secured with a cable bushing. Do not fold the cables!

2.40 SL m.m.
8.1.1 Erection and doweling of the lift
It is necessary to dowel the lift. For this you need a concrete floor with a thickness of at
least 200 mm (150 mm with base plate) and a quality of at least B25. In case of doubt a
test boring has to be performed and a dowel is to set in. Afterwards the dowel is tighten
with a torque which is described of the dowel manufacturer (example: Liebig Company
80 Nm).
If there are defectives (cracks or hairline cracks) in the zone of influence Ø200 mm, the
foundation cannot be used to install the lift on it.
pic.12: complete view: automotive lift with ascending pipe and traverse.
A foundation must be constructed in accordance with the data sheet “foundation plan”.
It must be paid attention of an even installation place of the lift because of a straight
contact between lift and concrete floor.

- 25 -
2.40 SL m.m.
• As protection against liquids, should before doweling put a thin foil between the base
plate and the concrete.
• Close after this the split between the base plate and the concrete with silicone.
• Bore holes to fix the dowels through the borings of the base plates (pic.13). Clean the
holes with pressure air. Put in the dowels. The lift manufacturer demands Liebig
safety dowels type B20 or equaly good dowels of other manufacturer (with licence)
but observe the regulation. (bore hole, torque...). Before doweling check the concrete
floor with quality B25 if the concrete floor goes to the top egde of the floor. In this
case the dowels have to be chosen according to pic.22. If the ground is covered with
floor tiles, the dowels have to be chosen according to pic.21.
• Lining up the column with spirit level.
• If necessary put thin metal sheets between the base plate and the floor until the lift is
in the correct vertical position and the contact between the base plate and the floor is
available.
• Tighten the dowels with the dynamometric key (example: Liebig-dowel 80 Nm).
Each dowel must be tightened with the demanded torque. Otherwise the normal
function of the lift can not guaranteed.
• If you need the cable not under the floor mount the traverse and the ascending pipe.
Secure the traverse against falling out. Do not hang any additional loads on the
traverse and the ascending pipe. (for an example: a ladder)
8.1.2 Electro mounting and current connection

A) with using cross-beam and ascending pipe
• Remove the cover at the top of the column.

• Lay the cable after the drawing (pic.17) in the ascending pipe and the traverse. Put
the correct plugs together.
Observe the secure contact between the plugs.
Plug in the 7-wire motor cable (with 2 plugs) in the head plate of the operating
column. Lay this cable over the ascending pipe and the traverse to the head plate of
the opposite side. Plug in the plug in the head plate of the opposite side.
Plug in the 3-wire potentiometer cable (with 2 plugs) in the head plate of the opposite
side. Lay this cable over the ascending pipe and the traverse to the head plate of the
opposite side. Plug in the plug in the head plate of the opposite side.
The 5-wire cable (with one plug) is for the main supply. Plug in the plug at the head
plate of the operating column.
• Push the cover sheets careful in the ascending pipe.

B) without using cross-beam and ascending pipe (under floor)
• It is possible to lay the cable under the floor.

• Do not need the traverse and the ascending pipe.
• Make a foundation in accordance with the drawing. The opening for the cable is in
the base plate of the lift.
• Pay attention to the cable if you mount the column.
• Lay the cable before positioning of the column through the empty pipe.
Move the column to the installation place. Lay the cable through the hole in the base
plate to the head plate of the column. Build the column. Pay attention the cables.
• Connect the cables (Plugs) in accordance with the drawing.(pic.19)
• Pay attention the cables does not touches the rotating parts.

8.1.3 Installation the carrying arms
• Install carrying arms and bolts top and bottom with enclosed circlips.
The carrying arms must be secured at both sides, otherwise a correct connection
between the lift carriage and the carrying arm can not be guaranteed.
• Lift and lower the lift with vehicle several times, tighten dowels a second time with
the correct torque. (Liebig 80 Nm)
8.2 Initiation
Before the initiation a security check must be performed. therefore use

form: First security check.
If the lift is installed by a competent person, he will perform this security check. If
the operator installs the lift by himself, he has to instruct a competent person to
perform the security check.
- 28 -
2.40 SL m.m.
The competent confirms the faultless function of the lift in the installation record and
form for the security check and allows the lift to be used.
Please send the filled installation record to the manufacturer after

installation.
8.3 Changing the installation place
If the place of installation shall be changed, the new place has to be prepared in
according to the regulations of the first installation. The changing should be
performed in accordance with the following points:
• Lift or lower the carriage to medium height.

• Take away current supply from the lift.
• Remove the cover of the lift.
• Dismount the carrying arms.
• Disconnect the plugs.
• If necessary remove the ascending pipe and the traverse.
• Loosen the dowels.
• Install the lift in accordance with chapter 8 “ Installation and Initiation”
Use new dowels, the used dowels can not be used anymore.
A security check must be performed before reinitiation by a competent person. Use

form “Regular security check”.
9. Security check
The security check is necessary to guarantee the safety of the lifting during use. It
has to be performed in the following cases:
1. Before the initial operation, after the first installation

Use the form “First security check before initiation”
2. In regular intervals after the initial operation, at least annually.
Use the form “Regular security check at least annually”
3. Every time the construction of that particular lift has been changed.
Use the form “Extraordinary security check”
The first and the regular security check must be performed by a competent
person. It is recommended to service the lift at this occasion.
After the construction of the lift has been changed (changing the lifting
height or capacity for example) and after serious maintenance works
(welding on carrying parts) an extraordinary security check must be
performed by an expert.
This manual contains form with a schedule for the security checks. Please us the
