1.2 PROPER USE
The trailer is designed for transport of harvested crops and agricultural products in the form
of pressed bales or blocks, at the farm and on public roads. The machine is also designed for
transporting harvested crops and agricultural products on EUR-pallets and in pallet boxes.
The trailer is equipped with stanchions and also suitable for carrying sawn or short wood.
TABLE 1.3 Recommended types of pallets
PALLET NAME - TYPE LENGTH
[mm]

[mm]
HEIGHT
[mm]
EURO pallet – standard 1,200 800 144
EUR – 1/2 800 600 144
EUR pallet – extended 1,200 1,200 144
ISO 1,200 1,000 144
The above-mentioned harvested crops, agricultural products and wood may be transported
provided that the recommendations included in this manual, especially the recommendations
concerning protection of loads included in Section (4.3.2), are adhered to. The trailer which is
suitable for being used on public roads may not be longer than 12 metres.
DANGER
The trailer must not be used for purposes other than those for which it is
intended, in particular:
•for transporting people and animals,
•for transporting hazardous loads or loads which are not properly
secured against shifting or falling out,
•for transporting any materials other than those stipulated in the
manual.
Therefore, while using thrust ladders and stanchions to carry wood, set the extendible frame
in such a way that the permissible length is not exceeded. It is forbidden to burden the rear
extendible frame with chunk wood. The frame is not suitable for being burdened with

PRONAR T028KM PRONAR T028ML SECTION 1
1.6
transversely arranged wood. The extendible frame can be used to transport long timber. If
the trailer is equipped with lifted hydraulic walls, it must not be used to tranpsort wood.
The trailer may only be hitched to the agricultural tractors which fulfil all the requirements
specified in table (1.4).
The brake system and the light and indicator system meet the requirements of road traffic
regulations. Do NOT exceed the permissible speed of the tractor-trailer combination (the
permissible speed in force in the country in which the trailer is used). 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 and WARRANTY BOOK and conform
with the recommendations contained in these documents,
•understand the machine'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 machine 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 machine 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 safe operation,
•have the required authorisation to drive and are familiar with the road traffic
regulations and transport regulations.
