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 as well as
loose and bulk 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 guarantee 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 is 30 km/h in
Poland (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 40 km/h.
