1.4 TERMS & CONDITIONS OF WARRANTY
PRONAR Sp. z o.o. Narew guarantees the reliable operation of the machine when it is used
according to its intended purpose as described in the OPERATOR'S MANUAL. The repair
period is specified in the WARRANTY BOOK.
TIP
Demand that the seller carefully and precisely fills out the WARRANTY BOOK
and warranty repair coupons. A missing date of purchase or sale point stamp,
may make the user ineligible for any warranty repair or refund.
The warranty does not apply to those parts and sub-assemblies of the machine, which are
subject to wear in normal usage conditions, regardless of the warranty period. Consumables
include the following parts/sub-assemblies:
•drawbar hitching eye,
•pneumatic system connector filters,
•tyres,
•seals,
•bearings,
•bulbs and LED lamps,
•brake shoes.
The warranty service only applies to factory defects and mechanical damage that is not due
to the user's fault.
In the event of damage arising from:
•mechanical damage which is the user's fault, caused by road accidents,
•inappropriate use, adjustment or maintenance, use of the machine for purposes
other than those for which it is intended,
•use of damaged machine,
•repairs carried out by unauthorised persons, improperly carried out repairs,

PRONAR T023, PRONAR T023M SECTION 1
1.10
•making unauthorised alterations to machine design,
the user will lose the right to warranty service.
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 warranty or not.
For detailed Terms & Conditions of Warranty, please refer to the WARRANTY BOOK
attached to each machine.
Modification of the machine 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 machine is prepared for sale completely assembled and does not require packing.
Packing is only required for the machine's technical documentation and any extra fittings. The
agricultural trailer is delivered to the user either transported on a vehicle or, after being
attached to a tractor, independently (towing with a tractor).
1.5.1 TRANSPORT ON VEHICLE
Loading and unloading of the agricultural trailer from vehicle shall be conducted using loading
ramp with the aid of agricultural tractor, overhead crane or hoisting crane. 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.
IMPORTANT!
Do not attach or hitch the trailer by drawbar eye, under-run protection devices,
mudguard brackets or other structural elements that are not sufficiently strong
to withstand operations of this type.
Lifting equipment used for transporting the machine must be attached only to the fixed
structural elements of the machine. These elements are, first of all: frame, transport catches
and axle.
The trailer should be attached firmly to the platform of the vehicle using straps or chains fitted
with a tightening mechanism. In order to attach the machine in a proper manner, use

SECTION 1 PRONAR T023, PRONAR T023M
1.11
transport lugs (1) – figure (1.3) and fasten axles, lower longitudinal members of the frame
and possibly structural elements of the rotating frame.
FIGURE 1.3 Transport lugs
(1) transport lug, (2) lower longitudinal member
Chocks, wooden blocks or other objects without sharp edges should be placed under the
wheels of the trailer to prevent it from rolling. Wheel blocks must be nailed to the vehicle load
platform planks or secured in another manner preventing their movement.
Use certified and technically reliable securing measures. Worn straps, cracked securing
catches, bent or corroded hooks as well as other damage may disqualify use of the given
element from use. Carefully read the information stated in the Operator's Manual for the
given securing measure. The number of securing elements (cables, straps, chains and stays
etc.) and the force necessary for their tensioning depends on a number of things, including
weight of the machine, the construction of vehicle carrying it, speed of travel and other
conditions. For this reason it is impossible to define the securing plan precisely.
A correctly secured machine does not change its position with regard to the transporting
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

PRONAR T023, PRONAR T023M SECTION 1
1.12
in order to immobilise the machine. If necessary, sharp edges of trailer should be protected at
the same time protecting the securing straps from breaking during transport.
DANGER
Incorrect application of securing measures may cause an accident.
During reloading work, particular care should be taken not to damage parts of the machine's
fittings or the paint coating. The tare weight of the agricultural trailer is given in table (3.1).
IMPORTANT!
When being road transported on a motor vehicle the trailer must be mounted
on the vehicle's platform in accordance with the transport safety requirements
and the regulations.
Driver of the vehicle should be particularly careful during travel. Centre of
gravity of the vehicle transporting the machine is shifted upwards, which poses
a threat to stability of the vehicle and transported machine.
Use only certified and technically reliable securing measures. Carefully read
the manufacturer's instructions for the securing measures.
1.5.2INDEPENDENT TRANSPORT BY THE USER
In the event of independent transport by the user, carefully read THE OPERATOR'S
MANUAL and follow its recommendations. Independent transport involves towing the
machine with own agricultural tractor to destination. During transport adjust travel speed to
the prevailing road conditions, but do not exceed the maximum design speed.
IMPORTANT!
Before transporting independently, the tractor driver must carefully read this
Operator's Manual and observe its recommendations.
