1 Introduction
The document ”Operating Instructions and Documentation” contains important information
about installation, operation and maintenance of the automotive lift.
To furnish proof of installation of the automotive lift the form ”Record of Installation” must be
signed and returned to the manufacturer.
To furnish proof of the first use, regular and extraordinary checks, this documentation contains
forms. Use these forms to document the checks. Note: The forms need to remain in this
documentation.
Any changes to the construction and displacement of the automotive lift must be registered in
the ”Master document”.
1.1 Installation and check of the automotive lift
Only specialist staff is allowed to do work concerning safety and to do the safety checks for the lift.
They are called experts and competent person in this document.
Experts are persons (i.e. self-employed engineers, experts), who have received instruction and
have experience to check and to test automotive lifts. They know the relevant labour
and accidents prevention regulations.
Competent persons are persons (i.e. service technicians of the manufacturer or dealer) who
have acquired adequate knowledge and experience with automotive lifts. They took
part in training from the lift-manufacturer.
1.2 Warning notices
To show danger and to show important information the three symbols below are used. Pay
attention to those passages, which are marked with these symbols.
Danger! This sign indicates danger to life. Inexpert handling of the described operation
may be dangerous to life.
Caution! This sign indicates a warning against possible damage to the automotive lift or
other material defects in case of inexpert handling.
Attention! This sign indicates an important function or other important notes.
