¾ Couple the machine only to such tractors
and transport it with tractors suitable for this
purpose.
¾ Couple the machine properly to the specied
devices!
¾ By coupling the machine to the front and/or
rear of a tractor you must not exceed:
• the permissible total weight of the tractor
• the permissible tractor axle loads
• the permissible tyre load bearing capacities
of the tractor tyres
¾ Secure both tractor and machine against
unintended rolling away before coupling or
uncoupling the machine!
¾ Persons are not allowed to stand between the
machine to be hitched up and the tractor, while
the tractor is moving towards the machine!
Possibly assisting persons must stay besides
the vehicles and may only step between the
vehicles when these are at standstill.
¾ Lock the operating lever for the tractor
hydraulics in a position in which accidental
lifting or lowering is ruled out!
¾ When hitching and uncoupling machines
move the supporting devices (if present) to
the corresponding position (stability)!
13
¾ When operating supporting devices there is a
risk of injury at crushing and shearing points!
¾ Be particularly cautious when coupling and
uncoupling the machine to or from the tractor!
There are crushing and shearing points at the
coupling point between tractor and machine!
¾ Persons are not permitted to stand between
tractor and machine when the hydraulics are
operated!
¾ Coupled supply lines

faults
• whether the parking brake is fully released
• the function of the brake system
¾ Always ensure sucient steering and braking
capacity of the tractor!
Machines attached to or towed by a tractor
or front or tail weights affect the driving
properties as well as the steering and braking
ability of the tractor.
¾ Observe the maximum payload of the mounted
/ hitched up machine and the permissible axle
and drawbar loads of the tractor!
¾ The tractor must secure the prescribed
braking deceleration for the load carrying
tractor/machine combination!
¾ Check the braking eect before setting o!
¾ Consider the width and centrifugal mass of
the machine when cornering with the machine
attached or hitched up!
¾ Before starting transport travels move all
pivotable machine parts into transport
position!
¾ Before starting transport travels lock all
pivotable machine parts in transport position
to prevent endangering position changes.
Use the dedicated transport locks for this
purpose!
¾ Before starting transport travels lock the
control levers for the hydraulics to prevent
accidental lifting or lowering of the attached
or hitched up machine!
¾ Before starting transport travels check
whether the necessary transport equipment
has been correctly mounted to the machine,
such as e.g. lighting, warning signs and
protective features!
¾ Match the travel speed to the prevailing
conditions!
¾ Shift to a lower gear before driving downhill!
¾ Always switch o single wheel braking (lock
the pedals) before starting transport travel!
¾ Pay attention to the notes in chapter Transport
travel.
1.6.6 Hydraulic system
WARNING
¾ The hydraulic system is under high pressure!
¾ Ensure correct connection of the hydraulic
hose lines!
¾ When connecting hydraulic hoses make sure
that the hydraulics has been depressurized
on both tractor and machine side!
¾ Blocking actuators on the tractor, which serve
the purpose of directly executing hydraulic or
electric movements of components, such as
e.g. folding, slewing and pushing processes,
is prohibited.
The corresponding movements must
automatically stop once you release the
corresponding actuator. This does not apply
to movements of equipment which
• are continuous or
• automatically controlled or
• require a floating or pressure position
because of their function
¾ Before starting work on the hydraulic system
• lower the machine to the ground
• depressurize the hydraulic system
• shut down the tractor engine
• apply the parking brake
• pull out the ignition key
15
¾ Pressure accumulator
Depending on the equipment the hydraulic
system may have a pressure accumulator
installed. Do not open or work (welding, drilling)
on the pressure accumulator. Even after being
emptied, the accumulator is still preloaded
by gas pressure. Always depressurize the
pressure accumulator before starting work on
the hydraulics. The pressure gauge (if present)
must not indicate any pressure. The pressure
in the pressure gauge must drop to 0 bar. Only
then may work be carried out on the hydraulic
system.
¾ Have the hydraulic hoses inspected by an
expert under occupational safety related
aspects at least once every year!
¾ Replace hydraulic hoses if damaged or
excessively aged! Use only genuine hydraulic
hoses from HORSCH LEEB AS!
¾ In order to avoid accidents caused by
undesired hydraulic movements or hydraulic
movements triggered by other persons
(children, passenger), the control units on the
tractor must be secured and locked when not
in use or in transport position.
1.6.7 Electric system
Always disconnect the battery (negative pole)
before starting work in the electric system!
¾ Use only the specied fuses. The use of fuses
with the rating too high will destroy the electric
system. Fire hazard!
¾ Make sure that the battery is correctly
connected. Connect the positive pole rst and
the negative pole after! When disconnecting
disconnect the negative pole rst and the
positive pole after!
¾ The utilization period of hydraulic hoses
should not exceed six years, including a
possible storage time of maximum two years.
Even if properly stored and under permissible
stress, hoses and hose connections are
subject to natural ageing, which limits their
shelf life and utilization period. Deviating
from this, the utilization period can also be
determined on the basis of empirical values,
particularly under due consideration of the
endangering potential. For hoses and hose
lines made of thermoplastics other guide
values may be decisive.
¾ Never try to seal o leaking hydraulic hoses
with your hands or ngers. Fluids (hydraulic
oil) escaping under pressure can penetrate
the skin and enter into the body causing
severe injury! If injured by hydraulic oil,
consult a doctor immediately! Danger of
infection!
¾ Due to the possible danger of severe infections,
one must use appropriate auxiliary means
when looking for leakages!
¾ Power sockets and connectors (electric,
pneumatic) should be identied by colour to
rule out operating errors.
¾ Always cover the positive battery pole with the
dedicated covering. Danger of explosion in
case of short-circuit to ground!
¾ Avoid sparking and naked flames in the
vicinity of the battery. Danger of explosion!
¾ The machine can be equipped with electronic
components and parts, the function of which
may be affected by the transmission of
electromagnetic waves from other equipment.
Such inuences may put persons in danger,
if the following safety notes are not complied
with.
In case of a subsequent installation of
electric appliances and/or components on
the machine, with connection to the on-board
power supply, the user is responsible for
checking whether this installation will cause
faults in the vehicle electronics or in other
components.
Make sure that the subsequently installed
electric and electronic components are
in accordance with the valid issue of the
EMC directive 2014/30/EC and are identied
with the CE-sign.

1.6.8 Towed machines
1.6.10 Pneumatic brake system
¾ Pay attention to the permissible combinations
of hitching device on the tractor and drawbar
hitch on the machine!
Couple only permissible vehicle combinations
(tractor and towed machine).
¾ In case of single-axle machines pay attention
to the maximum permissible drawbar load of
the tractor on the hitching device!
¾ Always ensure sucient steering and braking
capacity of the tractor!
Machines mounted to or towed by a tractor
aect the travel behaviour as well as the
steering and braking ability of the tractor,
especially single-axle machines with drawbar
load applied to the tractor!
¾ For drawbars with drawbar load, the height
of the drawbar must only be adjusted in a
specialist workshop!
1.6.9 Brake system
¾ Only drive o with the hitched up machine
after the operating pressure required to
release the brake has been reached (pressure
gauge on tractor).
¾ Before coupling the machine clean the seal
rings on the coupling heads of the supply and

¾ After setup and repair work on the brake
system you must generally carry out a brake
test!
¾ Pay attention to the corresponding regulations
(France) when changing the hydraulic oil!
¾ Only use the specied hydraulic oils (France)
when topping up or changing the hydraulic oil.
¾ When working on the tyres make sure that the
machine has been parked safely and properly
secured against rolling away and accidental
lowering (parking brake, wheel chocks).
¾ The assembly of wheels and tyres requires
adequate knowledge and the use of proper
assembly tools!
¾ Repair work on tyres and wheels must only
be carried out by specialists and only with the
appropriate assembly tools for this kind of work!
¾ Check the air pressure regularly! Pay attention
to the specied air pressure!

1.6.13 Handling crop protection
agents
¾ Follow the recommendations of the crop
protection agent manufacturers in regard to
• protective clothing.
• Warnings concerning the handling of crop
protection agents.
• Regulations for metering, use and cleaning.
¾ Store all relevant information about the used
crop protection agent (safety data sheets,
instructions for use, etc.) in the document
container.
¾ Pay attention to the notes in the “AID”
publications - No. 1237 “Crop protection
terminology” and No. 1042 “Caution when
handling crop protection agents”. (Only
available in German)
¾ The water quality (the water hardness and
mineral content in particular) inuences the
property of some fertilisers and crop protection
agents. Precipitation and deocculation can
cause deposits in lters and nozzles.
Example: Extremely hard water reacts with
sulphate-bearing fertiliser to form calcium
sulphate (gypsum) and causes white deposits
in the lters.
Pay attention to the conditions of use and
the combination possibilities given by the
corresponding manufacturers to avoid such
problems!
¾ Observe the data on compatibility of crop
protection agents with materials of the crop
protection sprayer!
¾ Do not spray any crop protection agents
that have a tendency to agglutination or
solidication!
¾ Wear suitable protective clothing when
handling crop protection agents.
¾ Do not eat, drink or smoke while handling crop
protection agents!
¾ Keep crop protection equipment and crop
protection agents out of the reach of children!
¾ Always ensure a sucient water supply in the
machine to be able to wash o crop protection
agent in the event of an emergency.
¾ In case of physical contact with crop protection
agents you may need to consult a physician.
¾ Thoroughly clean hands and face after the
end of work.
18
1.6.14 Operating the crop
protection sprayer
¾ Pay attention to the notes in the Plant
Protection Act!
¾ Observe the notes in the publications of the
“Federal Ministry for food, agriculture and
consumer protection”.
¾ Never open pressurized lines!
¾ Use only original spare hoses from HORSCH
LEEB AS, which will withstand the chemical,
mechanical and thermal loads. For assembly
you should generally use hose clamps made
of V2A!
¾ Please pay attention to the following when
repairing crop protection sprayers which have
been used with ammonium nitrate - carbonyl
diamide solution:
residues of ammonium nitrate - carbonyl
diamide solution can be form salt on or inside
the spraying mixture container through the
evaporation of water. This results in pure
ammonium nitrate and carbonyl diamide. In
its pure form, ammonium nitrate in connection
with organic matter, such as carbonyl diamide,
becomes explosive, if critical temperatures
(caused by e.g. welding work, grinding, ling)
are reached during repair work.
¾ By thoroughly washing off the spraying
mixture container or the parts to be repaired
with water, this risk can be eliminated,
because the salt of the ammonium nitrate carbonyl diamide solution is water soluble.
Therefore always clean the crop protection
sprayer thoroughly with water before starting
repair work!
¾ The rated volume of the spraying mixture
container must not be exceeded when lling!
¾ At the headland reduce the travel speed and
switch o the sprayer.
¾ Excessive, jerky steering movements at the
beginning and the end of a curve will put
extreme loads on the folding boom.
¾ When applying small droplets under strong
wind, the chemical can be blown about and
thus cause damage to others!
¾ If the soil is very dry, the applied chemical
can be blown away together with dust and
cause damage. Always wait until the soil is
suciently moist!
¾ Check the following from time to time:
Metering quantity, clogged nozzles, damage
to machine parts, leakage and cleanliness of
the machine.
¾ For tractors with cabins with ventilation fans
replace the fresh air lters with activatedcarbon lters!
¾ Ensure that the category of the tractor cabin
is approved for the respective crop protection
agent used.
¾ Do not ll crop protection sprayers with water
from open bodies of water - to protect man,
animal and environment!
¾ Always ensure a sucient water supply in the
machine to be able to wash o crop protection
agent in events of emergency.
¾ When using these preparations strictly
comply with the instructions for use and
the precautions listed issued by the crop
protection product manufacturer!
¾ Data concerning the preparations used must
always be kept in the transport box, so that
these are available for rescue services in case
of accidents.
¾ Fill the crop protection sprayer only through
original HORSCH LEEB AS lling equipment
and by gravity feed via the water mains!
¾ Never blow out nozzles and other small parts
with your mouth.
¾ Thoroughly clean hands and face after the
end of work.

1.15.3 Eects when using certain
crop protection agents
At the time the crop protection sprayer is
manufactured the manufacturer is aware of only
a few approved crop protection agents approved
by the Julius Kühn Institute, which could have
a damaging eect on the materials used in the
crop protection equipment.
We would like to point out, that e.g. crop
protection agents known to us, such as Lasso,
Betanal and Tramal, Stomp, Iloxan, Mudecan,
Elancolan and Teridox will cause damage to
hoses and switching diaphragms, if these are
exposed to such products over a longer period
of time (20 hours). The listed examples do not
claim completeness.
We particularly warn against the use of non-
permitted mixtures of two or more dierent crop
protection agents. Substances with a tendency
to agglutination or solidication must not be
placed.
When using such aggressive crop protection
agents it is highly recommended to spray these
immediately after the preparation of the spraying
mixture and thoroughly clean the system with
water after.
The materials and components used for the
HORSCH LEEB AS crop protection sprayers
are liquid fertiliser proof.
The area marked red indicates the danger zone
of the machine:
The danger zone of the machine contains
dangerous spots with permanently existing or
unexpected dangers. These danger spots are
marked with warning signs, which warn against
residual dangers that cannot be technically
eliminated by design. In these cases the special
safety regulations in the corresponding chapters
do apply.
No persons are to remain within the danger zone
of the machine,
¾ as long as the tractor engine is running with
the hydraulic system connected.
¾ as long as tractor and machine have not been
secured against unintended starting and
accidental rolling away.
The operator must only move the machine
or change cultivation tools from transport to
working position and vice-versa or drive these
implements, if the danger zone of the machine
is free of persons.
24
