1.4 CHECKING THE MACHINE AFTER DELIVERY
The manufacturer ensures that the trial is
fully functional, has been checked in ac-
cordance with control procedures and is
approved for use. However, this does not
release the user from the obligation to
check the machine after delivery and be-
fore rst use. The trial is delivered to the
user completely assembled. After delivery
of the machine to the recipient, the user is
obliged to check the technical condition of
the trailer. During the purchase, the user
must be informed by the seller about the
use of the machine, the dangers arising
from improper use, how to connect the
machine with the principle of operation
and construction. Detailed information on
the transfer can be found in the WARRAN-
TY BOOK
THE SCOPE OF CONTROL ACTIVITIES
• Check the completeness of the ma-
chine in accordance with the order
(standard and optional equipment).
• Check technical condition of guards,
safety devices.
• Check the condition of the paint coat-
ing, check for any signs of corrosion.
• Carry out visual inspection of indi-
vidual trailer elements for mechan-
ical damage resulting due to incor-
rect transport of the machine (dents,
punctures, bends or broken parts).
• Check the condition of the tires on
the road wheels and the air pressure
in the tires.
• Check the correct tightening of the
wheels.
• Check the technical condition of the
drawbar eye and its attachment.
• Check technical condition of pneu-
matic conduits.
• Check the technical condition of the
exible hydraulic hoses.
• Make sure there are no hydraulic oil
leaks.

draulic and electrical connections on
the agricultural tractor comply with
the requirements, otherwise do not
connect the trailer.
If all of the above activities have been car-
ried out and the technical condition of the
trailer does not raise any objections, con-
nect the machine to the tractor.
Start the tractor, check individual systems
and carry out a test run of the trailer and
perform a test drive without load (without a
loading box). It is recommended that visual
inspection be carried out by two people,
one of them should be permanently in the
tractor's cab. The test run must be carried
out in the order shown below.

• Improper operation of hydraulic and/
or pneumatic cylinders,
or other faults, you need to diagnose the
problem. If the fault cannot be rectied or
remedied, you will void the warranty, con-
tact the place of purchase for clarication

DANGER
The trailer may not be used for purposes other than
those for which it is intended. In particular, it is for-
bidden to:
• transport people, animals, dangerous materials,
aggressive loads as a result of chemical reactions
to trailer structural elements (causing corrosion of
steel, damaging paint coverings, dissolving plastic
elements, destroying rubber elements, etc.),
• transport of any materials other than those provid-
ed for in the instructions,
• transport improperly secured cargo that could cause
road and environmental pollution while driving,
• transport of incorrectly secured cargo, which could
change its position in the load box during driving,
• transport of cargo that location of the centre of
gravity adversely affects the stability of the trailer,
• carry loads that affect uneven loading and/or over-
loading of the axles and suspension components.
