1.2 PROPER USE
T900 movable wall 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 at a maximum
speed of 40 km/h.
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.

•for transporting machines and eq ipment, with high centre of gravity affecting
trailer stability,
•for transporting loads with neven loading and overloading of axles,
•for transporting nsec red loads, which may move in the load box platform,
•for transporting loads which may litter road s rface and road sho lder,
•for transporting constr ction materials s ch as debris, stones, bricks and similar
materials which may ca se damage to the trailer.
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 T900 SECTION 1

must be observed. The trailer speed must not, however, be greater than the maximum design
speed.

•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.
