information about installation, operation and maintenance of the lift.
To furnish proof of the installation of the automotive lift the form ”Record of
Installation” must be signed and returned to the manufacturer.
To furnish proof of the singular, regular and extraordinary check this documentation
contains forms. The forms should be used to document the checks. They should not be
removed from this documentation.
Every change of the construction and displacement of the automotive lift has to be
registered in the ”Master document” of the lift.

The automotive lift UNI-LIFT 5000 CLT / Plus is a lifting mechanism for lifting motor
vehicles with a laden weight of up to 5000 kg. The max. load distribution is 2:1 in or
against drive-on direction.
The wheel free lift is a lifting mechanism for lifting motor vehicles
with a laden weight of up to 3500 kg. The max. load distribution is 2:1 in or against
drive-on direction.
The automotive lift is only designed for servicing vehicles. It is not allowed to carry
persons with the lift. It is not allowed to climb on the lift or on the vehicle. It’s not allowed
to install the standard-automotive lift in a hazardous location or washing bays.

Operating Instruction and Documentation
UNI-LIFT 5000 CLT / Plus
- 11 -
• Normally, the lift lowers with a speed of 0,05 meters in a second.
If the speed increases, e.g. because of a leakage of the hydraulic system, the SST
detects the problem and stops the lift by closing the oil supply of the hydraulic
cylinders.
- Switch off the main switch.
- Control the complete hydraulic system and call your service partner if there is any
defect!
• The lift can be repaired by a competent person with knowledge and experience, who
has joined a special training of the lift manufacturer (Erectors of the manufacturer
and its retailers are competent persons).
CE-STOP (main lift and wheel free lift)
• When rail of the lift is approximately 320 mm high, the lowering stops automatically.
• 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.
• Push the button „lowering“ and keep it pushed until the lift has reached his lowest
position. You hear an acoustic signal while you lower the lift in his end-position.
Top-limit
• When the lift has reached his maximal height the SST stops the lift automatically.

automotive lift, 5000 kg for the automotive lift with wheel free lift.
• The laden weight of the lifted vehicle musn´t be more than 2500 kg for the wheel
free lift.
• The automotive lift must be lowered completely, before the vehicle is driving, in
the provided direction, on the lift.
• During working with the lift the operating instruction has to be followed.
