2. put the cylinder screw M5x20 DIN912 with a disc M5 DIN125A in the slit of the plate
3. move the plate so that the screw is on the end of the slit
4. counter the screw with a self-locking hex-nut M5 DIN985 and a disc M5 DIN125A
Attention! Do not lock the plate at the rope terminal! It must be movable!
5. on opposite side of the terminal each of the ropes must be counter-locked with 2 hex-nuts

staff will be called Experts and Competent persons.
Experts are persons (for example self-employed engineers, experts) which have received
instructions and have the appropriate experience to check and to test the automotive
lifts. They are aware of the work involved and know the accident prevention
regulations.
Competent persons are persons who have acquired adequate knowledge and experience with
automotive lifts. They have completed the appropriate training provided by the lift-
manufacturer (the servicing technicians of the manufacturer or dealer, are regarded as
competent)
1.2 Warning Symbols
The three symbols below are used to indicate danger and other important information. Pay
attention to areas on and around the lift that are marked with these symbols.
Danger! This sign indicates danger. Ignoring this warning may result in injury or
even death.

2.2 Application
The automotive lift is a lifting mechanism for lifting motor vehicles
with a laden weight of up to 4500 kg . The max. load distribution is 2:1 either in or against the drive-
on direction.
The automotive lift has been designed for servicing vehicles only. It has not been designed to carry
people. Carrying people either directly on the lift or in vehicles that are on the lift is therefore not
allowed.
The installation of the standard lift in hazardous or dangerous locations such as wash bays is
dangerous and is therefore not allowed.
Changes of construction, repairing and changes of place must be registered in this master
document.
