2 Safety
This manual contains instructions for your
safety and for safe operation.
The basic safety instructions include in-
structions that apply fundamentally to safe
use or maintenance of the safe condition of
the trailer.
The action-related warnings warn you
about residual hazards and are found be-
fore a dangerous action.
► Follow all the instructions to prevent
personal injury, environmental or prop-
erty damage.
2.1 Warnings

The warnings are classified according to
the severity of the danger. The following
explains the danger levels with their asso-
ciated signal words and warning symbols.
!

!
WARNING
Possible danger to life or serious injuries
CAUTION
Possible slight injuries, environmental
damage or property damage
WARNING
Possible serious injury caused by crushing
CAUTION
Possible slight injury caused by crushing
NOTE
Possible environmental damage or prop-
erty damage
2.2 Intended use
Intended use includes the observance of
all operating and maintenance instructions
supplied with the vehicle as well as the ob-
servance of the maintenance intervals and
conditions prescribed therein.
The KRONE trailer and its superstructures
are intended exclusively for legal transport-
ation purposes in compliance with applic-
able laws, rules and regulations.
Operational reliability of the vehicle is guar-
anteed only if all applicable instructions,
settings, laws, rules, regulations, and limit-
ations are fully complied with.
The trailer is produced with state-of-the-art
manufacturing systems in compliance with
all applicable safety-related laws, rules,
and regulations. Nevertheless, operation of
the trailer incorporates dangers for life and
limb of the operator and other personnel,
or danger of equipment damage, or opera-
tional problems.
► The trailer is to be operated only if in
technically adequate state, and in ac-
cordance with safety and danger-re-
lated laws, rules, and regulations, un-
der strict compliance with the opera-
tion instructions.
► Have any faults that could impair
safety immediately repaired by an au-
thorised specialist workshop.
The following also applies for trailers with
hydraulic rear width expansion:
The hydraulic rear width expansion is de-
signed and built to increase the loading
width of a KRONE trailer. The rear is ex-
panded via a manual hydraulic pump. In
the widened condition, approx. 500mm of
additional loading width per side is avail-
able. This means a maximum total loading

SAFETY
Operating instructions • Load Carrier • 505410638-02 • 07/2019 11
width of 3480mm. The hydraulic rear width
expansion must be retracted again after
loading and unloading. Do not drive with an
extended rear width expansion (when ex-
panded). Intended use also includes read-
ing the operating instructions and following
all the instructions that they contain - par-
ticularly the safety instructions. In addition,
all inspection and maintenance work must
be performed at the required time intervals.
Only qualified specialist personnel may
work on the hydraulic rear expansion.
The following also applies for trailers with
Ice-Protect Easy:
The roof tarp lifting device (Ice-Protect
Easy) is used to prevent water accumulat-
ing on the roof tarp of a trailer and/or to re-
move any water accumulations already on
the roof tarp. In addition, the raised roof
tarp prevents the accumulation of condens-
ation building up on the inside of the roof
tarp. If the tarp roof is raised, the trailer
may reach a height which is above the per-
mitted limit values for road operations. The
roof tarp lifting device must be lowered
prior to departure. It needs to be operated
by trained personnel. Other persons must
not linger in the danger area of the roof
tarp lifting device. Maintenance may only
be carried out by specialist staff. Any other
use is not intended and can result in dam-
age to the vehicle and the device.
○ The device is only to be operated if in
technically perfect condition and only
as intended, with awareness of safety
and hazards, and in compliance with
the operation instructions.
○ Have any faults that could impair
safety immediately repaired by an au-
thorised specialist workshop.
○ Do not use the roof tarp lifting device if
ice sheets have already formed on the
roof tarp.
Foreseeable misuse
Any use going beyond proper transport us-
age is considered non-intended. Avoid the
following:
○ Transport of persons or animals
○ Transports that are subject to special
regulations, e.g. dangerous goods
transports
○ Transport of unsecured loads
○ Transport of materials, which, due to
their properties, do not ensure safe
handling and transport or only with ad-
ditional equipment
○ Exceeding the technically permitted
weights, axle loads and drawbar loads
○ Exceeding the maximum vehicle
speed
○ Exceeding the permitted length, width
and height dimensions (including by
driving with an expanded rear)
○ Use of components that are not ap-
proved by KRONE, e.g. tyres, ac-
cessories, spare parts
Fahrzeugwerk Bernard KRONE GmbH &
Co. KG is not liable for damage resulting
from non-intended use. Risks deriving from
such infractions are exclusively borne by
the operator.
2.3 Personnel qualification and
requirements
KRONE trailers and KRONE superstruc-
tures as well as their operating compon-
ents may only be used and maintained by
persons who have the respective qualifica-
tion and who have read and understood
the operating instructions.
In the operating instructions, a distinction is
made between
