5.2 Lowering the vehicle
• Lower the vehicle at the height for working or until the rails reach the lowest
point; push the lever “lowering“.
• If the lift is on the limit stop. Push the lever slowly on position “lowering“,
otherwise the hose burst check valve can be closed and the lift does not lowered.
• 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.
• If the lift is in the ratchet - push the lever “lifting“ until the ratchets are free and
than lower the lift again.
• (Optional): CE-STOP. Before the lift reaches its lowest position, the lift stops automatically
After the lift has stopped, check the danger areas around the lift. Push the lever “lowering”
again. A acoustic 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.
5.3 Equalisation of the rails
Continuous duty of the lift without reaching the lowest position there might be an
un equalisation of the two rails functionally. Normally equalisation of the lift returns
after a few minutes (cooling time of hydraulic oil).
In case the un equalisation of the two rails remains you should perform as follows to
regain the lift’s function:
Equalisation must be performed without vehicle, otherwise the vehicle might fall down.
• Lower the lift in the lowest position.
• Drive off the vehicle from the lift.
• Remove the cover of the operating unit.
• Raise the lift on approx. 400mm;
• Turn equalisation lever 90° upside and hold it in this position.
• Push the lever “lifting or lowering“ until the rails have the same height.

7. 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.
7.1 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.
• Clean the piston-rod using compressed air.
Grease the piston rods with a high capacity lipid (approx. 5 g of S2 DIN51503 KE2G
available from the Renolit Company.
• Check the function of the ramps and the roll-over safety device.
• Check the stripper of the cylinder.
• Clean and lubricate the moving parts of the lift (hinge bolts, sliding pieces, sliding surfaces)
grease with a multipurpose lipid (example: Auto Top 2000 LTD. Agip).
• Grease the lubricate nipples with a multipurpose lipid. (example: Auto Top 2000 LTD. Agip).
• Check all the safety devices of the lift.
Execution of the lubrication:
• The bolts of the automotive-lift must be are checked by an expert. (We recommend the
execution of the examination by a person which during a work training participated.)
After the examination the hinge bolts and bearings are to be lubricated. In the case of strong
contamination the bearings are to clean at least outwardly.
• Lubricate the movable parts. (bolts, sliding blocks, sliding surfaces)
The assigned sliding bearings are appropriate for the unlubricated operation. In case of
normal operating conditions no lubrication is necessary.
With intensified operating conditions, e.g. with the work with corrosion-aggressive media,
with strong dirt and dusty condition, with painting fog, etc. exists the danger of the corrosion
and/or the penetration of foreign matter into the bearings. An improved protection of the
bearings can be achieved by lubrication.
Therefore we recommend the precautionary lubricating of all hinge bolt bearings.
• Use a lubrication spray with good creep characteristics in case by using hinge bolts without
lubrication nipples. Inject the surfaces of the bolts.
Before spraying clean the bearings carefully at least outwardly.
During the lubrication procedure the bearing must be relieved. The relevant safety regulations
are to be considered
After the lubrication, raise and lower the automotive-lift several times without load.

It is necessary to lubricate in regular intervals. In the case of usual use of the automotive-lift we
recommend monthly lubrication intervals. In the case of strong demand of the automotive-lift
the lubrication intervals must be shortened accordingly.
Recommended lubricants:
Grease: each commercial grease e.g..
! Attention: Do not use greases with fixed lubricants (e.g. graphite, Mos2) use.
Lubrication spray: trade-usual lubrication sprays
! Attention: Do not use lubrication spray with silicon parts.
• Check the electrical parts, electric cables and channels for Damage.
• 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 the function and condition of the safety ratchets. Grease the sliding surfaces.
• 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).
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).
• Examine the hydraulic lines for leakage (visual check).
Life time of hydraulic hoses:
The use duration of the hose lines should not exceed six years, including a storage time of
two years.
• The hydraulic oil has to be changed at least once a year. To change the oil, lower the lift into
its lowest position. Empty all tanks and refill with clean oil, approx. 11 litres per hydraulic unit
are needed.
Use an ATF-Suffix hydraulic-oil (OEST Company) if the ambient temperature is under 5
degrees centigrade. After filling, the hydraulic oil must be between the upper and lower
markings of the oil level gauge.
Remove the old oil according to the appropriate regulations.
• Check that all screws and bolts are correctly torque (turning moments, see the list Pic. 6)

A regular and appropriate maintenance practice will aid the preservation of the lift.
No guarantees can be given when damage (egg rust or fading colour) is the direct result of poor
maintenance and cleaning practice.
Regular cleaning of all kinds of dirt is the best protection against wear and the formation of rust
and will prolong the life of the lift
- Dirty deposits that can cause rust include:
• de-icing salt
• sand, pebble stone, natural soil
• all types of industrial dust
• water; also in connection with other environmental influences
• all types of aggressive deposits
• constant humidity caused by insufficient ventilation
Obviously this is dependent on the type of work being done with the lift, the degree of
cleanliness of the workshop and location of the lift. The degree and amount of dirt is dependent
on the season, on the weather conditions and the ventilation of the workshop.
During poor conditions it may be necessary to clean the lift once week, but cleaning once a
month will suffice.
Clean the lift and the floor with a non-aggressive and non-abrasive detergent. Use a gentle
detergent to clean the parts. Use an standard washing-up liquid and lukewarm water.
- Do not use steam jet cleaners.
- Remove all dirt carefully with a sponge or if necessary with a brush.
- Ensure that no washing-up liquid is left on the lift after cleaning.
- Do not use aggressive means for cleaning the workshop floor and the automotive lift.
- A permanent contact with any kind of liquid is not allowed. Do not use high
pressure devices for cleaning the lift.
8. 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 adequate form
for the security checks. The form should remain in this manual after they have been filled out. In
the following there is a short description about special safety devices.

hydraulic oil must be between the upper and low marking of the oil level gauge.
• Push lever ”up” of the lift until the vent screw at the top of master cylinder is
accessible.
• Open the vent screw (cylinder screw with copper ring), located at upper side in guide
bush of master cylinder. (Do not turn vent screw out completely) until oil comes out
of the bore-hole. Shut vent screw immediately and fasten it.
• If the ratchets of the lift engage before oil comes out of the vent screw, shut the vent
screw and lift the lift with lever ”up” until the ratchet is not engaged any more.
• Afterwards repeat deaerating as described until oil comes out of the ventilating
screw.
• Carry out equalisation of the rails as described in chapter ”operating instructions”

Operating Instruction and Documentation

- 20 -
• Raise the UNI-LIFT to a height of 1500 mm.
• Adjust the lift: first one base plate, than the second base plate. If there is an uneven floor
even it with metal sheets. A continuous contact between the floor and the base plate must be
guaranteed to avoid hollow spaces. Dowel the lift:
Nußbaum Company demands LIEBIG safety dowels (German dowel manufacturer) or
equivalent dowels of other manufacturer but: observe their regulations.
Before doweling check the concrete floor (with quality B25!) if the concrete floor goes to the
top edge of the floor. For an existing concrete floor the dowels have to be chosen according
to Pic. 7. If floor tiles are on the concrete floor, the dowels have to be chosen according Pic.
8. Its important for the trouble-free working that the base plate are clean and the guides of
the sliding block are clean and greased.
Check the adjustment of the base plates and dowel the lift: Bore the holes to fix the dowels
through the borings of the base plates. Clean the holes with pressure air. Put in the safety
dowels.
• If necessary dowel the operating unit at the floor.
• Tighten the Liebig-dowels with the dynamometric key (M = 80Nm).
Each Liebig dowel must be tightened with the demanded torque. Otherwise the normal
and secure function of the lift can not guaranteed. Observe the regulations of the
other dowel-manufacturer.
• Raise and lower the lift several times with load. Check the torque of the dowels and check
the hydraulic hoses tightness.
• Equalize the lift, if this is necessary.
• Mount the covers: Do not damage the cables.
9.3 Initiation
Before the initiation a security check must be performed. Therefore use form: First
security check.

security check.
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 the installation.
9.4 Changing the installation place
If the place of installation shall be changed, the new place has to be prepared in according to
