Intended use
HUMBAUR vehicles and bodies are
constructed in accordance with the
technological regulations and the
recognised safety regulations. Despite
this, however, if used for other than their
intended purpose, they can pose a
hazard to life and limb for both users and
third parties, or cause damage either to
the HUMBAUR vehicle itself or to other
property.
HUMBAUR vehicles and bodies are
manufactured exclusively for transport
operations in accordance with all
relevant regulations and provisions.
Proper use entails adherence to
regulations, descriptions and instructions
provided in this manual and the
suppliers' operating and maintenance
manuals.
If you are planning to make subsequent
modifications to your HUMBAUR vehicle
or vehicle body, place an enquiry with
Humbaur GmbH in good time.
Always check with Humbaur GmbH an
approved HUMBAUR workshop before
having accessories fitted to your
HUMBAUR vehicle or body.
The following is permitted:
– Transport of goods
– Operation only in the range of the
total permitted payload
– Operation only with suitable towing
vehicle and approved coupling
– Operation only in when in technically
perfect condition
– Operation with uniform weight
distribution of the load
– Driving only with properly secured
load
– Driving only when in compliance with
maximum legal speed and speed
adjusted to poor road and weather
conditions
– Loading and unloading only in secure
areas or with additional safeguards in
public streets
– Only stop/park the trailer with
safeguards to prevent rolling away
Periodically subjecting the trailer to the
general inspection and safety inspection
by specialists as well as the certification
of this is a prerequisite to participating in
road transport.
The operator/user of the trailer is
obligated to regularly care for/clean the
trailer as well as perform maintenance.
HUMBAUR vehicles/bodies
carry a VIN (vehicle identification
number), see page 33.
Always quote the VIN when
making enquiries or ordering
parts.

Reasonably foreseeable misuse
Any use that goes beyond use for
transport in accordance with the relevant
regulations is considered to be improper.
That includes, in particular:
– Transport of people/animals
– Transport of goods subject to special
regulations and/or for which special
vehicle versions are necessary (e.g.
chemical substances)
– Loading with exceeded payload
– Exceeding the maximum permissible
axle/bearing/trailing load
– Transport of hot/liquid materials (e.g.
tar)
– Driving only with poorly or unsecured
load
– Driving with poor load distribution
(one-sided, selective loading)
– Unauthorised constructional changes
to the trailer or those not approved by
the manufacturer
– Use of non-authorised replacement
parts or accessories
– Driving with defective lighting system
or with faulty electrical system
– Driving with trailer dirty so that the
license/number plate, lighting,
markings are not visible or not clearly
visible
– Driving with open structures (e.g.
platform gates, curtains, doors, lids,
toolbox, side guards, etc.)
– Unauthorised maintenance/repair of
safety-relevant components which
must only be maintained or repaired
by specialists
– Driving with excessive/inappropriate
speed in poor weather conditions
and/or on bad roads
– Parking trailer without taking
sufficient safety precautions to
prevent the trailer from rolling away
– Operating the trailer in a damaged
condition and visible part wear or with
broken safety-relevant components
– Operating a trailer without a valid
traction test with the towing vehicle
– Operating the ramps when a person
is in the danger area
– Transport of vehicles/loaded goods
which protrude over the total width of
the trailer
Any liability for damage resulting from
non-compliance is refused by the
manufacturer:
Humbaur GmbH
Mercedesring 1
86368 Gersthofen (Germany)
The operator / user shall bear sole
responsibility for any such risk.

Traction test
A traction test must be completed to
ensure correct usage.
Unlike a drum brake, a disc brake does
not produce any detectable reduction in
the braking effect to the driver when
overloaded.
This overload can mean that the brakes
of the towing vehicle or trailer overheat.
Reduced braking force, greater brake
lining or brake disk wear as well as wheel
bearing or axle damage can occur as a
consequence of overloaded brakes.
For optimal distribution of the
deceleration of the entire vehicle
combination, a traction test must be
conducted on the loaded vehicle's brake
system by an independent brake service
in compliance with 71/320 EC or ECE
R13 after a short run-in time of 2,000 to
5,000 km or within 14 days following
vehicle handover and each time the
towing vehicle is changed.
Fig. 1 Warning panel on the trailer
In the event of non-compliance
with any of the above or failure to provide
the results of a traction test, any warranty
claims made against Humbaur
GmbH will be invalidated.
All resulting risks and liability waivers
shall continue to apply in the event that:
- acceptances have been carried out
by testers/experts from the technical
testing authorities or officially recog-
nised organisations,
- approvals have been granted by
public authorities.

The warranty covers
Defects occurring in the course of correct and
proper use of the trailer which are caused by the
design or can be traced back to material defects.
Repairs carried out during the warranty period do
not extend this period.
The dealer as the contracting party is respon-
sible for the warranty.
Prerequisites:
Original replacement parts must be used during
repairs.
Repairs must be carried out by an approved
workshop.
The manufacturer's maintenance directions and
instructions set out in this operating manual must
have been followed.
Defects may not be traced back to
Non-compliance with the technical and legal
regulations set out in this operating manual.
Improper use of the trailer or lack of user experi-
ence.
Unauthorised modifications to the trailer or built-
on accessories not approved by Humbaur GmbH
will invalidate the warranty. Non-observance of
the relevant legal regulations.
The following are not defects
Every trailer is a product manufactured by
craftsmen. Although every care has been taken,
minor, superficial scratches can occur that have
no effect on the intended use.
Production-related stress cracks in the surface
(hairline cracks) cannot be avoided. These hair-
line cracks have not effect on the stability or use
of the trailer.
Gaps between platform gate and loading ramp.
Furthermore, polyester components are not
100% colour-fast. UV and weather influences
can give rise to bleaching here too.
It must also be noted that rubber part generally
age due to UV influences, and the surface may
be subject to cracking and bleaching.
Parts coated by electro dip painting (edp) are not
colour-fast. They may bleach as a result of UV
radiation.
Galvanised parts are normally not glossy, but
lose their lustre after a short period of time. This
is not a defect, but instead a desired quality since
full protection against metal corrosion is only
guaranteed by oxidation. Wood is a natural
material. For this reason, in spite of the most
varied types of machining and coating, it is
subject to natural, weather-dependent stretching
or shrinkage, which can lead to distortions.
Natural wood blemishes and unevenness are
normal for this natural material and can show on
the surface. Bleaching caused by UV radiation
and weather influences is possible. A manufac-
turing tolerance regarding thickness is defined
for the wood components used. Claims cannot
be made for deviations within the tolerance
band.
Because trailers are generally not insulated,
condensation may form under curtain and poly-
ester covers in the event of temperature fluctua-
tions. In this event, ensure adequate ventilation
to prevent mould from forming. Trailers are not
100% watertight either. Water may get in through
doors, flaps and windows even when rubber
seals are used and applied with the utmost care.

Service and warranty claims
16 Safety
1
