• 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 snowcovered, 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.
