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 serial number of the agricultural trailer
or the serial number of the axle, therefore it is recommended that these
numbers are inscribed in the table (1.2).
1.2 INTENDED 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 for 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.
The machine can be aggregated with agricultural tractors only.
The trailer is designed and constructed according to current safety 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
must be observed. The trailer speed must not, however, be greater than the maximum design
speed of 40 km/h.

Pronar T682, Pronar T682/1 SECTION 1
1.6
IMPORTANT
The trailer must not be used for purposes other than those for which it is
intended. DO NOT:
•transport people, animals, hazardous materials, chemically
aggressive loads that will corrode the structural elements of the trailer
(causing corrosion of steel, destruction of paint coat, dissolving
plastic elements and destruction of rubber elements etc.),
•transport incorrectly secured load, which during travel may cause
contamination of the road and natural environment,
•transport incorrectly secured load, which during travel may change
position in load box or fall out of the load box,
•transport loads, whose centre of gravity may destabilise the trailer,
•transport loads, which have uneven load distribution and/or overload
axles and suspension elements.
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 and the WARRANTY BOOK and
follow instructions 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 meets all the Manufacturer’s
requirements.
