3 Safety information
3.1 Intended use
The GN container food serving trolley is used to present food in Gas-
tronorm containers (GN containers) and keep it cold during food distri-
bution.
The cold well holds GN containers with food. Cold wells keep pre-
cooled food cold.
Intended use includes following the prescribed procedures, complying
with the given specifications, and using the genuine accessories that
are provided or additionally available. Any other use of the transport
trolley is considered inappropriate.

3.2 Improper use
The GN container food serving trolley is not to be used as a self-
service trolley.
The GN container food serving trolley is not suitable for machine
cleaning.
It may not be used for transporting living creatures. Persons must not
sit or stand on or in the transport trolley.
In the case of improper use, the manufacturer and suppliers shall
assume no liability for resulting damage. Damage caused by improper
use shall result in loss of liability and of guarantee claims.
3.3 Safety instructions
3.3.1 General information
The transport trolley may only be used in a technically sound condition,
taking risks and safety into consideration, for its intended purpose and
in accordance with the operating instructions.
All operating elements and controls must be in a technically sound
condition and functioning reliably.
Before each use, the transport trolley must be checked for any visibly
apparent damage and defects. If damage occurs, immediately notify
those responsible and take the transport trolley out of use.
Changes or conversions are only permitted after consultation and
written consent from the manufacturer.
Transport trolleys can move off independently and in an uncontrolled
manner if the castors are not locked.
3.3.2 Transport
If the transport trolley needs to be lifted, only use lifting gear and
load-bearing equipment approved for the total weight of the transport
trolley.
Only use transport vehicles that are approved for the total weight of the
transport trolley.
The transport trolley does not have any attachment points for eyelets
or similar lifting aids.
If the transport trolley is transported, it must be additionally secured
during transport. The locks on the castors are not sufficient as trans-
port securing devices. They must not be braked during transport on an
HGV because the locking mechanism will be damaged by the forces
that occur.
