1.2 PROPER USE
The trailer is designed for transport of harvested crops and agricultural products as well as
loose, bulk and long load materials 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 contrary to its intended purpose.
The trailer is not intended or designed for transporting people, animals or goods classified as
dangerous materials.
ATTENTION
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,
•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.
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
trailer is used, the limits stipulated by the road traffic legislation in force in a given country

Pronar T679M SECTION 1
1.6
must be observed. The trailer speed must not, however, be greater than the maximum design
speed of 40 km/h.
Using it as intended also involves all actions connected with the safe and proper operation
and maintenance of the machine. Due to the above, the user is obliged to:
•carefully read the OPERATOR'S MANUAL of 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,
•only hitch the trailer to an agricultural tractor, which fulfils all the requirements
made by the trailer's Manufacturer.
The trailer may only be used by persons, who:
•are familiar with the contents of this publication and with the contents of the
agricultural tractor Operator's Manual,
•have been trained in trailer operation and work safety,
•have the required authorisation to drive and are familiar with the road traffic
regulations and transport regulations.
