TIP
In the event of ordering a replacement part or in the case of the appearance of problems
it is often essential to give the factory n mbers of parts or the VIN n mber of the trailer,
therefore it is recommended that these n mbers are inscribed in the spaces below.
1.2 PROPER USE
The trailer is designed for transport of harvested crops and agricultural products (loose, bulk
and long materials, etc.) as well as loads on EUR-pallets and pallet boxes at the farm and on
public roads. It is acceptable to transport construction materials, mineral fertilisers and other
loads, if fulfilling conditions indicated in section 4. Non-compliance with the recommendations
of the carriage and loading of goods described by the Manufacturer and the road transport
regulations in force in the country in which the trailer is used, shall void the warranty and is
regarded as use of the machine not according to its intended purpose.
The trailer is not intended or designed for transporting people, animals or goods classified as
dangerous materials.
The trailer is constructed according to current safety requirements and engineering
standards. The brake system and the light and indicator system meet the requirements of
road traffic regulations. The maximum speed of the trailer on public roads in Poland is 30
km/h (pursuant to Traffic Law Act of June 20th 1997, article 20). In the countries where the

SECTION 1 Pronar T683
1.5
trailer is used, the limits stipulated by the road traffic legislation in force in a given country
must be observed. The trailer speed must not, however, be greater than the maximum design
speed of 40 km/h.
IMPORTANT
The trailer m st not be sed for p rposes other than those for which it is intended. The
ser MUST NOT:
•transport people, animals, hazardo s materials, chemically aggressive loads
that will corrode the constr ction elements of the trailer (ca sing corrosion of
steel, destr ction of paint coat, dissolving plastic elements and destr ction of
r bber elements etc.),
•transport incorrectly sec red load, which d ring travel may ca se
contamination of the road and nat ral environment,
•transport incorrectly sec red load, which d ring travel may change position
in load box or fall o t of the load box,
•transport loads, whose centre of gravity may destabilise the trailer,
•transport loads, which have neven load distrib tion and/or overload axles
and s spension elements.
Using it as intended also involves all actions connected with the safe and proper operation
and maintenance of the machine. In connection with this the user is obliged to:
•carefully read the OPERATOR'S MANUALof the trailer and the WARRANTY
BOOK and conform with the recommendations contained in these documents,
•understand the trailer's operating principle and how to operate it safely and
correctly,
•adhere to the established maintenance and adjustment plans,
•comply with general safety regulations while working,
•prevent accidents,
•comply with the road traffic regulations and transport regulations in force in a
given country, in which the trailer is used,
•carefully read the Operator's Manual and comply with its recommendations,

Pronar T683 SECTION 1

•only hitch the trailer to an agricultural tractor, which fulfils all the requirements
made by the trailer's Manufacturer.
