• Ingestion: Do not induce vomiting. Seek immediate medical attention.
• The lift shall not be exposed to direct, external weather conditions (snow, rain, etc.).
• The lift shall not be erected, stored and commissioned in explosion- and fire-endangered
operating halls or in moisture-endangered rooms (wash halls). Above and beyond this, storage
is only allowed in enclosed rooms.
• The lift shall only be positioned and operated on an even surface.
• The maximum permissible inclination of the surface is 2 %.
• The underground surface shall be paved (cement, blacktop) and have sufficient solidity to bear
the load of the pressure forces that are created.
• The static friction between the underground and the lift contact surface shall be sufficient to
prevent sudden slipping. The lift shall not be used on snow-covered, icy underground surfaces.
The lift shall not be positioned and operated on surfaces which have been contaminated with
oil, gasoline or lubricants.
• It is forbidden to operate the lift on unpaved surfaces (e.g. grass, gravel etc.).
• Clean up the underground surface which may endanger the solid stance of the lift before
erection (e.g. gravel, stones).
• No objects (wooden boards etc.) shall be laid under the lift to compensate for uneven surfaces.
In this case, another, safer erection spot shall be chosen.
• The lift’s erection surface shall be cleared and kept clean of any objects sticking to it or any
other impurities (gravel, oil).
• Before lifting a vehicle, the lift stability shall be checked by the operating personnel.
• Vehicles shall only be lifted if the lift has been removed from the transport unit (forklift, brakable
dolly).
• An additional stroke length extension or lifting of the loaded lift is forbidden.
• The lift shall only be moved with suitable lifting and transport devices (ground conveyor). The
supports of the lifting and transport units shall fit to the supplied transport frame. Only forklifts
and dollies designed to meet valid machinery directives shall be used.
• The forks of the used lifting and transport unit (ground conveyor) shall be placed at least 1000
mm deep in the transport frame.
