especially endangered:
Wear the personal protective outt stipulated
in the safety data sheet of the crop protection
agent last used when cleaning the crop protection sprayer.
¾ Keep children away from the machine.
¾ Especially before drive o and before trigger-
ing machine movements you must make sure
that the danger zone is free of children.
¾ Shut down the tractor before leaving it.
Children can trigger dangerous machine
movements. An insuciently secured machine parked without being attended poses
a danger for playing children!
Personal protective outt
WARNING
Health hazards caused by accidental contact with crop protection agents or spraying
mixture!
Wear personal protective outt:
¾ when preparing the spraying mixture
¾ when cleaning / replacing the spraying noz-
zles, during spraying operation, during all
work for cleaning the crop protection sprayer
after spraying operation.
NOTE
The owner must provide the necessary personal
protective outt as specied by the manufacturer
of the crop protection agent used.
NOTE
Do not enter the tractor cabin with contaminated protective outt!
Safety in trac
DANGER
No passengers are allowed to ride on the
machine!
¾ Pay attention to the permissible transport
widths and heights. Pay attention to the transport height when passing under bridges and
low hanging overhead power lines.
To wear the required protective outt always
observe the operating instructions and the safety
data sheet of the crop protection agent used.
Missing or incomplete protective equipment
increases the risk of health damage. Personal
protective equipment includes, e.g.:
¾ overall resistant to chemicals

¾ face protection
¾ safety goggles to protect against splashes
¾ Respirator
¾ Provide effective protective equipment in
proper condition.
¾ Never wear rings, bracelets or other jewellery.
¾ When driving on public roads comply with the
respective national road trac regulations!
¾ Do not exceed the permissible axle load, tyre
load bearing capacity and total weight, in or-
der to ensure sucient steering and braking
capabilities. The front axle must be loaded
with at least 20 % of the tractor weight.
¾ For machines without brake select the weight
of the tractor and the speed so that the machine can be managed securely under all
conditions.
¾ The tractor must ensure the adequate supply
of the brake system of the connected vehicle.
10
¾ Travel characteristics, steering and braking
ability are inuenced by attached or hitched

decisive for the design dependent top
speed.
Always match the travel mode to the
road conditions to avoid accidents and
damage to the undercarriage.
Consider your personal abilities, carriage
way, trac, sight and weather conditions.
In addition, pay attention to the notes in
chapter Commissioning!
Safety in operation
Commissioning
The operational safety of the machine cannot be
guaranteed without orderly performed commissioning. This can lead to accidents with severe
or even fatal physical injuries.
¾ The machine must only be put into operation
after receiving instructions by employees of
the authorized dealer or a HORSCH employee.
¾ The machine registration form must be com-
pleted and returned to HORSCH.
All protective features and safety equipment,
such as detachable protective devices (wheel
chocks, etc.), must be correctly in place and
reliably functioning before the machine is put
into operation.
¾ Check nuts and bolts, especially on wheels,
regularly for a tight t and re-tighten if necessary.
¾ Check the tyre pressure at regular intervals,
see maintenance overview.
Damage to the machine
Damage to the machine can impair the operational safety of the machine and cause accidents. This can lead to severe or even fatal
physical injuries.
The following machine parts are particularly
important for safety:
¾ Hydraulics
¾ Brakes (if available)
¾ Connecting features
¾ Protective features
¾ Lighting
11
If in doubt about the safety-relevant status of
the machine, e.g. in case of leaking operating
uids, visible damage or unexpected changes
in travel behaviour:
¾ Immediately shut down and secure the ma-
chine.
¾ If possible locate and rectify the faults by fol-
lowing these operating instructions.
¾ Rectify possible causes for damage (e.g. re-
move dirt and tighten loose screws).
¾ Have damage that could aect safety and
that cannot be rectied by you rectied by a
qualied expert workshop.
Hitching and uncoupling
Faulty coupling of the machine to the pulling tool
of the tractor causes dangers, which could result
in severe accidents.
¾ Strictly comply with all operating instructions:
• These operating instructions (chapter Con-
necting, Transport position and Parking)
• Operating instructions of the tractor
• if necessary the operating instructions for
the propshaft
¾ Exercise special caution when reversing the
tractor. Never stand between tractor and
machine.
¾ Only park the machine on a rm and level
surface.
¾ Secure the machine against rolling away.
¾ Do not uncouple the machine with the folding
boom unfolded, with empty spraying mixture
containers. Negative drawbar load can cause
the crop protection sprayer to tip over.
Hydraulics
The hydraulic system is under high pressure.
Escaping uid can penetrate the skin and cause
serious injuries. In the event of injury, consult a
doctor immediately.
The machine’s hydraulics has several functions,
which can cause injury to persons or damage to
the machine if operated incorrectly.
¾ Do not connect/disconnect hydraulic hoses
to/from the tractor before both the hydraulics
on machine and tractor are de-pressurised.
¾ Lock all hydraulically operated parts before
any work on the hydraulic system. Depressurise the hydraulics on the tractor and implement side.
¾ The hydraulic system is under high pressure.
Check all lines, hoses and screwed connections regularly for leaks and any visible
external damage!
¾ Use only appropriate means when searching
for leaks. Repair any damage immediately!
Oil sprays can cause injuries and re!
¾ Power sockets and connectors on the hydrau-
lic connections should be marked in order to
exclude operating errors.
¾ In the case of injury, contact a doctor imme-
diately!
¾ Secure and lock the control unit on the tractor
if not in use!
¾ Replace hydraulic hoses at the latest after six
years, see Maintenance overview.
Pressure accumulator
The hydraulic system may be equipped with
pressure accumulators.
12
¾ Do not open or work (welding, drilling) on
pressure accumulators. Even when empty,
the tanks are still preloaded by gas pressure.
The hydraulics must be depressurized before
maintenance!
Brake system
What to do in case of voltage ashover
Depending on the equipment, the machines can
be equipped with a pneumatically or hydraulically operated service brake system.
For road travel the brake system must always
be connected and fully functional.
¾ After coupling the machine and before trans-
portation you should always check the function and condition of the brake system.
¾ Check the setting on the brake pressure
regulator.
¾ Always release the parking brake before start-
ing to drive.
¾ Always secure the machine against rolling
away and apply the parking brake before
unhitching.
Adjustments and repair work on the brake system must only be carried out in a professional
workshop or by an operator, who has been
specially trained by HORSCH for this purpose.
Overhead lines
When unfolding or folding the folding boom, the
machine may reach the height of overhead lines.
Possible voltage ashover to the machine may
cause fatal electric shock or re.
¾ Keep a safe distance to electric high voltage
power lines when unfolding or folding the folding boom.
¾ Never unfold or fold the folding boom in the
vicinity of power poles and power lines.
¾ With the folding boom unfolded and raised,
keep a sucient distance to electric high voltage power lines.
¾ Never leave or access the machine under
overhead lines to avoid possible risks of
electric shock or voltage ashover.
¾ When operating the sprayer under high volt-
age power lines disable the BoomControl and
operate the slope compensation manually.
Voltage ashover generates high electric voltages on the outside of the machine. This results
in extreme voltage dierences at the ground
around the machine. Wide strides, laying on the
ground or supporting yourself with your hands
on the ground can cause life-threatening electric
currents (pace voltage).
¾ Do not leave the cabin.
¾ Do not touch any metal objects.
¾ Do not create a conductive connection to
ground.
¾ Warn persons: DO NOT come near the ma-
chine. Electric voltages at the ground can
cause severe electric shock.
¾ Wait for professional rescuers. The overhead
power line needs to be switched o.
If persons need to leave the cabin despite the
voltage ashover, e.g. in case of a potential lifethreatening risk of re:
¾ Jump away from the machine. Ensure a safe
stand when jumping. Do not touch the outside
of the machine.
¾ Move away from the machine with short step-
ping strides.
PTO-shaft / propshaft
Persons can be caught, pulled in and seriously
injured by the rotating PTO-shaft or propshaft.
Before switching on the PTO-shaft:
¾ Always make sure that the PTO-shaft guard
is in place and fully functional.
¾ Make sure that the chosen rotary speed and
the sense of rotation of the propshaft or PTOshaft correspond with the permissible values
for the machine.
¾ Make sure that no persons are inside the dan-
ger zone around the PTO-shaft or propshaft.
Never switch on or couple the PTO-shaft while
the tractor motor is shut down.
¾ Shut down the PTO-shaft if the angles are too
large. The machine could become damaged.
Parts may be thrown o and injure persons.
13
¾ Switch o the PTO-shaft if it is no longer
needed.
¾ Ensure sucient overlapping of prole tube
and PTO-shaft guard.
¾ Allow PTO-shaft locks to click into place.
¾ Secure the PTO-shaft guard with chains
against rotating.
¾ Before assembly/disassembly of the prop-
shaft as well as before all interventions on
the machine:
Uncouple the PTO-shaft (shut o from the
tractor cab), switch o the tractor engine, pull
o the ignition key and wait until all parts have
come to a standstill.
¾ Follow the operating instructions for the
propshaft.
Technical limiting values
If the technical limiting values of the machine
are not complied with, the machine may sustain
damage. This can lead to accidents with severe
or even fatal physical injuries.
The following technical limiting values are of
particular importance for safety:
• Permissible total weight
• maximum axle loads
• maximum drawbar load
• Top speed
See chapter Technical data, type plate and type
approval.

droplets are ne and the wind is strong. This
may cause damage to people and nature!
¾ If the soil is very dry, the applied chemical can
be blown away together with dust and cause
damage. Ensure sucient moisture of the soil!
¾ For tractors with cabins with ventilation fans
replace the fresh air lters with activatedcarbon lters! Observe notes and instructions
of the tractor manufacturer.
¾ Ensure that the category of the tractor cabin
is approved for the respective crop protection
agent used.
¾ Always ensure a sucient water supply in the
machine to be able to wash o crop protection
agent in events of emergency.
¾ Data concerning the preparations currently
used must always be kept in the document roll
so that these are available for rescue services
in case of accidents.
¾ Observe the national legislation and regula-
tions on crop protection!
¾ The personal protective outt stipulated in
the safety data sheets of the crop protection
agent manufacturers must be carried along
and worn during work.

Changing equipment / wear items
¾ Only pulling tools may be attached that meet
the technical requirements according to these
operating instructions.
HORSCH does not assume any liability for
damages resulting from the attachment of
non-tting pulling tools as well as incorrect
mounting.
¾ For machines with valid type approval only
pulling tools may be attached that are covered
by the type approval. Attaching pulling tools
not covered by the type approval will void the
registration.
¾ Secure the machine against unintended roll-
ing away!
¾ Secure raised frame parts you have to work
under with suitable supports!
¾ Caution! Risk of injury caused by projecting
parts (e.g. folding boom parts)!
¾ Assume ergonomic working postures with any
assembly work.
Do not step on moving or other rotating parts to
climb onto the machine. You could fall and be
seriously injured.
Crop protection agents and liquid fertiliser
Improper handling of crop protection agents and
liquid fertiliser may cause poisoning and death.
¾ Follow the specications and instructions in
the safety data sheet of the crop protection
agent manufacturer. If necessary, ask the
dealer for the safety data sheet or safety
notes.
¾ Determine and provide the personal protective
outt as specied by the manufacturer of the
crop protection agent.
¾ At the time the crop protection sprayer is
manufactured the manufacturer is aware of
only a few approved crop protection agents,
which could have a damaging eect on the
materials used in the crop protection sprayer.
¾ Store all relevant information about the crop
protection agents used (safety data sheets,
instructions for use, etc.) in the document roll.
¾ The water quality (the water hardness and
mineral content in particular) inuences the
property of some fertilisers and crop protec-
tion 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 han-
dling 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 events of 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.
¾ Extended exposure time of crop protec-
tion agents may cause damages to plastic
components of the crop protection sprayer.
Follow the notes of the crop protection agent
manufacturers.
¾ The application notes of the crop protection
agent manufacturers must be observed when
mixing dierent crop protection agents.
15
Environmental protection
Crop protection agents and liquid fertiliser as
well as operating materials such as hydraulic
oil, lubricants, etc. can damage the environment
and the health of persons.
For equipment inuencing the weight or weight
distribution the regulations concerning towing
facility, support and axle load must be checked
and complied with.
For machines without brakes a brake system
may need to be retrotted if the permissible
weight limits are exceeded.
¾ Do not allow operating materials to drain out
into the environment.
¾ Pick up drained operating materials with ab-
sorbent material or sand, ll it into a leak tight
container and dispose of in accordance with
statutory regulations.
¾ Do not ll crop protection sprayers with water
from public bodies of water.
¾ Filling in water protection zones is not permit-
ted, depending on the crop protection agent
used! Inquire with the “Water board” to be on
the safe side!
¾ Observe the national and country-specic
regulations and standards (e.g. water protection areas).
Retrotting and
conversions
Structural changes not approved by HORSCH
may aect the functionality and operational
safety of the machine and will void any warranty
claim.
HORSCH is not liable for damages to life and
limb as well as property damages resulting from
unapproved retrotting and conversions.
¾ Do not perform any structural changes to the
pulling tool of the machine.
¾ Do not make any structural changes or ex-
tensions to the machine that have not been
approved by HORSCH.
¾ Modications and extensions approved by
HORSCH are only to be performed at an authorized workshop or by an operator who has
been trained by HORSCH for this purpose.
¾ Comply with country-specic instructions for
weights, weight distribution and dimensions.
In case of changes concerning data mentioned
on the type plate, a new type plate with updated
data must be attached.
In case of changes which concern the data in
the type approval, this type approval needs to
be renewed.
Care and maintenance
Inappropriate care and maintenance puts the
operational safety of the machine at risk. This
can lead to accidents with severe or even fatal
physical injuries.
DANGER
¾ Danger of poisoning - Do not climb into
the spraying mixture container!
¾ Conform to prescribed schedules for repetitive
tests or inspections.
¾ Service the machine according to the mainte-
nance plan, see chapter Care and maintenance.
¾ Only perform the work described in these
operating instructions.
¾ Before starting maintenance and service work
park the machine on level and rm ground and
secure it against rolling away. Clean the crop
protection sprayer, especially all parts which
are contaminated by spraying mixture. Wear
the stipulated protective outt when cleaning.
¾ Lock hydraulically operated parts and depres-
surise the hydraulic system.
¾ Prior to working on the electrical system,
disconnect it from the electric current supply.
16
¾ When performing welding work on the ma-
chine, disconnect the cables from computers
and other electronic components. The ground
connection must be as close as possible to
the welding point.
¾ Secure all operating media like compressed
air and hydraulics against unintended commissioning.
¾ Secure the raised machine or raised machine
parts against accidental lowering before starting maintenance, repair and cleaning work!
¾ Repair work inside the spraying mixture con-
tainer must only be performed after thorough
cleaning and wearing protective outt with a
respirator. This work must be monitored by a
second person outside the spraying mixture
container for safety reasons! Ensure sucient
ventilation of the spraying mixture container!
Only approved qualied personnel may enter
the spraying mixture container!
¾ Before cleaning the machine with high pres-
sure cleaner cover all openings, which should
stay clear of water, steam or cleaning agents
for reasons of safety or operation. Do not aim
the water jet directly on electric or electronic
components and bearings.
¾ When cleaning with high pressure cleaning
equipment or steam jets keep a distance of
at least 50 cm to machine components.
¾ After cleaning, check all hydraulic lines for
leaks and loose connections.
¾ Check for chang and signs of damage. Rem-
edy any faults immediately!
¾ Screw connections loosened for the purpose
of care and maintenance work must be
retighten after work is completed.
¾ Dispose of oils, greases and lters according
to regulations!
¾ If protective features are subjected to wear,
they must be inspected at regular intervals
and replaced in due time
¾ Do not clean new machines with a steam jet
of a high pressure cleaner. The paint takes
approx. 3 months to cure and could be damaged before this time.
¾ 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 may 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) are reached during repair work.
By thoroughly cleaning 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.
¾ All other maintenance and repair tasks,
which are not described in the operating
instructions, must only be carried out by
an authorized professional workshop or
by an operator who has been trained by
HORSCH for this purpose.
