1.5 Intended use
Use of the self-propelled PT is considered intended, if
the following points are accounted for during operation
of the machine.
Te manufacturer will not assume liability for any dam-
age resulting from unintended use, the risk must be
solely borne by the user.
• The self-propelled machine is intended for the trans-
portation and application of crop protection products
(insecticides, fungicides, herbicides, and others) in
form of suspensions, emulsions and mixtures as well
as of liquid fertilisers.
• The sprayer is solely intended for agricultural appli-
cations in the treatment of plantations. It is compliant
with the latest technical standard and, when correct-
ly set and adjusted and with the correct metering, it
ensures biological success.
• The machine must only be operated for its intended
use if in a technically perfect condition, whilst being
aware of safety and risks and in strict compliance
with the operating instructions!
• The working machine is operated by just one person
sitting in the cabin.
• The PT 280 is a working machine, which must only
be driven on public roads in strict compliance with
the permitted axle loads.
• Any faults that could adversely affect occupational
safety must be eliminated immediately!
• Defective or excessively strained parts must be
replaced immediately. The machine must otherwise
not be operated.
• Use only genuine HORSCH-LEEB-AS spare parts
for repairs. Other spare parts have not been tested
and approved by HORSCH LEEB AS and may have
a negative inuence on machine characteristics or
severely affect the safety.
• Changes to the machine, which may have a neg-
ative effect on safety, are only permitted with the
consent of the manufacturer.
Slopes may be passed in
• contour line
travel direction to the left 15 %
travel direction to the right 15 %
• Fall line
uphill 15 %
downhill 15 %
Intended use also includes:
• compliance with all notes in these operating instruc-
tions.
• compliance with the specied inspection and mainte-
nance work.
• the sole use of genuine HORSCH LEEB AS spare
parts.
Any use different than described above is prohibited
and is considered unintended.
For damage caused by unintended use
• the operator is solely responsible
• HORSCH LEEB AS GmbH will not assume liability.
1.5.1 Intended equipment of the self-
propelled crop protection sprayer
The intended equipment of the crop protection sprayer
results from the combination of
o basic unit and chassis
o tyres
o pressure tting
o pump equipment
o spraying boom
o spraying lines with half-width control and option-
al equipment
