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 and
bulky 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 concerning 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 the 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 trailer is designed 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 Road Traffic 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 30 km/h.

•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. Due to the above, the user is obliged to:
