1.2 PROPER USE
The trailer is designed for transporting agricultural and construction machines and the loads
which can be properly secured against moving during travel (loads placed in boxes,
containers, on pallets etc.). Transporting people, animals, bulk and hazardous materials is
forbidden and regarded as contrary to the intended purpose of the trailer. During the use of
the machine comply with all road traffic regulations and transport regulations in force in the
given country, and any breach of these regulations is regarded by the Manufacturer as use
contrary to its intended purpose.
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.

the user will lose the right to warranty service.
TIP
Dema d that the seller carefully a d precisely fills out the Warra ty Book a d guara tee
repair coupo s. A missi g date of purchase or sale poi t stamp, may make the user
i eligible for a y warra ty repair or refu d.
The user is obliged to report immediately on noticing any wear in the paint coating or traces
of corrosion, and to have the faults rectified whether they are covered by the guarantee or
not. Detailed guarantee regulations are contained in the WARRANTY BOOK attached to
each machine.
Modification of the trailer without the written consent of the Manufacturer is forbidden. In
particular, do NOT weld, drill holes in, cut or heat the main structural elements of the
machine, which have a direct impact on the machine operation safety.
1.5 TRANSPORT
The trailer is ready for sale completely assembled and does not require packing. Packing is
only required for the machine's technical documentation and any extra fittings. The trailer is
delivered to the user either transported on a vehicle or, after being attached to a tractor,
independently (trailer towed with a tractor).

Pronar RC2100 SECTION 1
1.10
1.5.1 TRANSPORT ON VEHICLE.
Loading and unloading of trailer from vehicle shall be conducted using loading ramp with the
aid of an agricultural tractor. During work adhere to the general principles of Health and
Safety at Work applicable to reloading work. Persons operating reloading equipment must
have the qualifications required to operate these machines. The trailer must be properly
connected with the tractor according to the requirements in this Operators Manual. The trailer
brake system must be started in checked before driving off or onto ramp.
The trailer should be attached firmly to the platform of the vehicle using straps or chains fitted
with a tightening mechanism. Securing elements should be attached to the transport catches
designed for this purpose (1) Figure (1.3) or to permanent structural elements of the trailer
(longitudinal members, crossbars etc.). Transport catches (hooks and eyes) are welded to
upper longitudinal frame (2), with one pair on each side of the trailer. Use certified and
technically reliable securing measures. Worn straps, cracked securing catches, bent or
corroded as well as other damage may disqualify use of the given element from use.
Carefully read the information contained in the Operator's Manual for the given securing
measure. Chocks, wooden blocks or other objects without sharp edges should be placed
under the wheels of the trailer to prevent it from rolling. Trailer wheel blocks must be nailed to
the low platform planks of the vehicle or secured in another manner preventing their
movement. The number of securing elements (cables, straps, chains and stay etc.) and the
force necessary for their tensioning depends on a number of things, including weight of the
trailer, the construction of vehicle carrying trailer, speed of travel and other conditions. For
this reason it is impossible to define the securing plan precisely. A correctly secured trailer
does not change its position with regard to the transport in vehicle. The securing elements
must be selected according to the guidelines of the Manufacturer of these elements. In case
of doubt apply a greater number of securing straps in order to immobilise the trailer. If
necessary, sharp edges of trailer should be protected at the same time protecting the
securing straps from breaking during transport.
During reloading work, particular care should be taken not to damage parts of the machine's
fittings or the lacquer coating. The tare weight of the trailer in condition ready for travel is
given in table (3.1).
