Foreseeable misuse
Any use extending beyond the prescribed transport
applications is regarded as other than intended.
This applies to all models.
– Transporting people.
– Transporting animals is types of trailers not designated
for animal transport.
– Transporting hot materials (e.g. tar).
– Transporting goods which are subject to special
legislation and / or require special types of vehicle
(e.g. chemicals, foodstuffs, hazardous goods).
– Loading with a payload that is too heavy.
– Driving with poorly secured / unsecured load.
– Driving with a poor load distribution (one-sided, spot
loading).
– Drivingatanunsuitablespeedinbadweatheraswellas
on a bad road surface.
– Driving with vehicle body not closed (covers, drop side,
side wall extensions, tarpaulin, etc.).
– Drivingwithafaultylightingsystemormalfunctionofthe
lighting system.
– Exceeding the max. permissible axle / drawbar and
trailer load.
– Not reaching the minimum drawbar load
(negative drawbar load).
– Making constructional changes to the trailer not
approved or authorised by the manufacturer.
– Using unapproved spare parts or accessories.
– Removing the type plate or VIN on the trailer or making
them illegible.
– Exceeding the max. permissible top speed of 80 km / h
or 100 km / h respectively.
– Parking the trailer without taking safety precautions
against it rolling away, such as applying the hand brake,
using wheel chocks.
– Operating the trailer with visible wear of parts or
breakage of safety-relevant components and
accessories.
– Operating the trailer when it is damaged, which can
cause danger on public roads and could also lead to
personal injury.
– Passingonthetrailerwithouthandingovertheoperating
manual or providing an explanation of the known
residual risks.
– Maintenance of safety-relevant components, such as
brakes, drawbar, hydraulic system, etc. by a layperson.
As the manufacturer, we do not accept any liability
for personal injury or material damage caused by
foreseeable misuse.
Disclaimer
Any liability of the manufacturer becomes null and void if:
– the trailer and its components are altered without
authorization.
– Original parts or conversion parts / accessories
approved by Humbaur GmbH are replaced by other
components.
– retrospective changes have been made to the trailer
(e.g. new drill holes in the frame or the reboring of
existing drill holes in the frame). This is considered by
Humbaur GmbH to be a structural change, and the type
approval therefore becomes null and void.
– Non-approved accessories or third-party spare /
component parts which are not original HUMBAUR
parts are attached or installed. The type approval of the
trailer, possibly even the insurance cover, becomes null
and void.
– care and maintenance intervals prescribed by the
manufacturer are not complied with.
Any risks and liability exclusions resulting from this also
exist if:
– Acceptance inspections have been carried out by
inspectors / authorised experts of the technical
inspection authorities or officially recognised
organisations.
– Official approvals are available.

1Service and warranty
10 Safety
The warranty covers
Defects that occur during proper use of the trailer as specified,
or which are design related or can be attributed to material
faults.
Repairs carried out during the guarantee period do not extend
it. As the contracting party, the dealer is responsible for the
warranty.
Requirements
Original replacement parts must be used for repairs. Repairs
mustbe carriedout bya specialistworkshop.Themaintenance
instructionsand regulationsof themanufactureraslistedinthis
operating manual must be observed.
Defects must not be attributable to
–Non-compliance with technical and legal regulations listed
in this operating manual, improper use of the trailer of lack
of experience of the user.
–Unauthorised alterations to the trailer and the use of fittings
not approved by Humbaur GmbH. These will invalidate the
warranty.
– Non-compliance with the respective statutory
regulations.
The following are not defects
Each trailer is a hand-made product. Despite the greatest of
care, minor superficial traces which have no effect on the
intended use can occur during assembly. Stress cracks in the
surface(hairlinecracks) caused duringmanufacturecannot be
avoided.Thesehairline cracks havenoeffect on stabilityorthe
use of the trailer.
The small gap between the drop sides and loading bridge
required for it to work is also not considered to be a defect.
Polyester components are not 100% colour-fast. Here, too, UV
and weather effects can colour changes.
Rubber parts will degenerate when exposed to UV light; it is
also possible for small cracks to form or for the surface to fade.
Parts coated with the electrocoat process are not colour-fast.
They can fade as a result of UV irradiation.
Galvanised parts are not normally shiny as they lose their
bright finish after a short time. This is not a defect but rather a
desired effect, as full protection against rusting of the metal is
only guaranteed after oxidation.
Wood is a natural material. That is why despite the various
types of processing and coating, it can be subject to natural
weather-dependent expansion or shrinkage which can cause
tension. Wood grain and irregularities are normal for this
natural material and can appear on the surface. Colour
changes are also possible as a result of UV irradiation and
weathering effects. A manufacturing tolerance is specified for
the thickness of the wooden components used. Claims will not
be accepted for deviations within the tolerance.
As the trailers are not generally insulated, temperature
fluctuations can result in the formation of condensation under
tarpaulins and polyester covers. In this case, adequate
ventilation should be provided to prevent mould growth.
Furthermore, the trailers are not 100% watertight. Water
ingress at doors, flaps and windows is still possible, even with
extremely careful workmanship and the use of rubber seals.
The warranty will not be valid if
–The operating, maintenance, cleaning and inspection
regulations are not complied with for technical changes to
the trailer.
–In the event of independently added fittings and
superstructures which have not been approved by
Humbaur.
–In the event of overloading and improper use of the trailer.
–If non-original Humbaur replacement parts are used.
– If the safety instructions on the trailer are not observed.
–If the service intervals are not adhered to, including for
Humbaur-fitted parts such as the axle, brakes, drawbar,
hydraulic systems etc.
–In the event of incorrect surface treatment of the materials
used.
–In the event of continued use of the trailer even though
defects have already been detected and reported and the
use has been prohibited by the manufacturer until repairs
have been carried out.
–In the event of continued use of the trailer with known
defectswhere repairisnotpossibleor istime-consuming or
is only possible with significant additional expense and
reduced function.
The warranty does not include
–Expenditure for ongoing maintenance.
–Costs due to normal wear and tear or after not being used
for a long time.
–Faults that can be attributed to not treating the trailer as
specified.
–Defects that can be attributed to the use of non-original
Humbaur replacement parts.
–Defects as a result of an improper repair.
–Defects that can be attributed to structural alterations or
assembly work on the vehicle.
–Damagewhichcanbetraced backto snowandwater loads
on tarpaulin / plywood or poly bodies.
– The manufacturer reserves the right to make design
changes.
