transporting people or animals.
ATTENTION!
The man re spreader m st not be sed for p rposes other than those for which it is
intended, in partic lar:
•for transporting people and animals,
•
for applications in which the maximum carrying capacity is
exceeded,
•for spreading and transporting toxic and flammable materials,
•for spreading fluids, sand or fibrous substances,
•for transporting unsecured loads, which may move
in the load box
during transport,

Pronar NV161/1 │ NV161/2 │ NV161/3│ NV161/4 │ NV161/5 SECTION 1
1.6
•
for transporting machines and equipment with high centre of
gravity deteriorating manure spreader stability,
•
for transporting construction materials, single objects or any
materials and substances outside the scope of inte
nded use of the
manure spreader.
The manure spreader 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 manure spreader on
public roads is 30 km/h in Poland (pursuant to Traffic Law Act of June 20th 1997, article 20).
In the countries where the manure spreader is used, the limits stipulated by the road traffic
legislation in force in a given country must be observed. The manure spreader speed must
not, however, be greater than the maximum design speed.
Using it as intended also involves all actions connected with the safe and proper operation
and maintenance of the machine. In connection with this the user is obliged to:
•carefully read the OPERATOR'S MANUAL of the manure spreader and the
WARRANTY BOOK and conform with the recommendations contained in these
documents,
•understand the manure spreader'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 manure spreader is used,
•carefully read the Operator's Manual and comply with its recommendations,
•only hitch the manure spreader to an agricultural tractor which fulfils all the
requirements made by the Manufacturer of the manure spreader.
The manure spreader may only be used by persons, who:
