9

Children in danger
Children are not able to assess dangers and may
behave unpredictably. Children are therefore
especially endangered:
¾Keep children away from the machine.
¾Especially before drive o󰘯 and before trigger-
ing machine movements you must make sure
that the danger zone is free of children.
¾Shut down the tractor before leaving it.
Children can trigger dangerous machine
movements. An insu󰘲ciently secured ma-
chine parked without being attended poses
a danger for playing children!
Personal protective outt
WARNING
Health hazards caused by accidental con-
tact with crop protection agents or spraying
mixture!
Wear personal protective out󰘰t:
¾when preparing the spraying mixture
¾when cleaning / replacing the spraying noz-
zles, during spraying operation, during all
work for cleaning the crop protection sprayer
after spraying operation.
To wear the required protective out󰘰t 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.:
¾overall resistant to chemicals
¾protective gloves resistant to chemicals
¾shoes resistant to chemicals
¾face protection
¾safety goggles to protect against splashes
¾Respirator
¾Provide effective protective equipment in
proper condition.
¾Never wear rings, bracelets or other jewellery.
Wear the personal protective out󰘰t stipulated
in the safety data sheet of the crop protection
agent last used when cleaning the crop protec-
tion sprayer.
NOTE
The owner must provide the necessary personal
protective out󰘰t as speci󰘰ed by the manufacturer
of the crop protection agent used.
NOTE
Do not enter the tractor cabin with contami-
nated protective outt!
Safety in tra󰀩c
DANGER
No passengers are allowed to ride on the
machine!
¾Pay attention to the permissible transport
widths and heights. Pay attention to the trans-
port height when passing under bridges and
low hanging overhead power lines.
¾When driving on public roads comply with the
respective national road tra󰘲c regulations!
¾Do not exceed the permissible axle load, tyre
load bearing capacity and total weight, in or-
der to ensure su󰘲cient steering and braking
capabilities. The front axle must be loaded
with at least 20 % of the tractor weight.
¾For machines without brake select the weight
of the tractor and the speed so that the ma-
chine can be managed securely under all
conditions.
¾The tractor must ensure the adequate supply
of the brake system of the connected vehicle.
10

¾Travel characteristics, steering and braking
ability are in󰘱uenced by attached or hitched
up equipment and ballasting weights. You
should therefore pay attention to su󰘲cient
steering and braking ability!
¾Before road travels check the correct connec-
tion of the supply lines:
• the brake and hydraulic system for apparent
faults
• whether the parking brake is fully released
• function of the service brake
For road transport the machine must be set to
transport position. The folding boom must be
folded up and secured. The stroke of the paral-
lelogram and optional steering must always be
blocked via the shut-o󰘯 valve before road travel,
see chapter shut-off valve.
¾Check lighting, warning and protective features
for functioning and cleanliness.
The permissible maximum speed speci-
󰘰ed in the type approval must be com-
plied with for transport on public roads!
The speci󰘰cations in the type approval
document or in the technical data are
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, tra󰘲c, 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 commis-
sioning. This can lead to accidents with severe
or even fatal physical injuries.
¾The machine must only be put into operation
after receiving instructions by employees of
the authorized dealer or a HORSCH em-
ployee.
¾The 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.
¾Check nuts and bolts, especially on wheels,
regularly for a tight 󰘰t and re-tighten if neces-
sary.
¾Check the tyre pressure at regular intervals,
see maintenance overview.
Damage to the machine
Damage to the machine can impair the op-
erational safety of the machine and cause ac-
cidents. This can lead to severe or even fatal
physical injuries.
The following machine parts are particularly
important for safety:
¾Hydraulics
¾Brakes (if available)
¾Connecting features
¾Protective features
¾Lighting
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:
¾Immediately shut down and secure the ma-
chine.
¾If possible locate and rectify the faults by fol-
lowing these operating instructions.
¾Rectify possible causes for damage (e.g. re-
move dirt and tighten loose screws).
¾Have damage that could a󰘯ect safety and
that cannot be recti󰘰ed by you recti󰘰ed by a
quali󰘰ed 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.
¾Strictly 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
¾Exercise special caution when reversing the
tractor. Never stand between tractor and
machine.
¾Only park the machine on a 󰘰rm and level
surface.
¾Secure the machine against rolling away.
¾Do 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.
¾Do not connect/disconnect hydraulic hoses
to/from the tractor before both the hydraulics
on machine and tractor are de-pressurised.
¾Lock all hydraulically operated parts before
any work on the hydraulic system. Depres-
surise the hydraulics on the tractor and im-
plement side.
¾The hydraulic system is under high pressure.
Check all lines, hoses and screwed con-
nections regularly for leaks and any visible
external damage!
¾Use only appropriate means when searching
for leaks. Repair any damage immediately!
Oil sprays can cause injuries and 󰘰re!
¾Power sockets and connectors on the hydrau-
lic connections should be marked in order to
exclude operating errors.
¾In the case of injury, contact a doctor imme-
diately!
¾Secure and lock the control unit on the tractor
if not in use!
¾Replace hydraulic hoses at the latest after six
years, see Maintenance overview.
Pressure accumulator
The hydraulic system may be equipped with
pressure accumulators.
¾Do 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!
12

Brake system
Depending on the equipment, the machines can
be equipped with a pneumatically or hydrauli-
cally operated service brake system.
For road travel the brake system must always
be connected and fully functional.
¾After coupling the machine and before trans-
portation you should always check the func-
tion and condition of the brake system.
¾Check the setting on the brake pressure
regulator.
¾Always release the parking brake before start-
ing to drive.
¾Always secure the machine against rolling
away and apply the parking brake before
unhitching.
Adjustments and repair work on the brake sys-
tem 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.
¾Keep a safe distance to electric high voltage
power lines when unfolding or folding the fold-
ing boom.
¾Never unfold or fold the folding boom in the
vicinity of power poles and power lines.
¾With the folding boom unfolded and raised,
keep a su󰘲cient distance to electric high volt-
age power lines.
¾Never leave or access the machine under
overhead lines to avoid possible risks of
electric shock or voltage 󰘱ashover.
¾When operating the sprayer under high volt-
age power lines disable the BoomControl and
operate the slope compensation manually.
What to do in case of voltage ashover
Voltage 󰘱ashover generates high electric volt-
ages on the outside of the machine. This results
in extreme voltage di󰘯erences 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).
¾Do not leave the cabin.
¾Do not touch any metal objects.
¾Do not create a conductive connection to
ground.
¾Warn persons: DO NOT come near the ma-
chine. Electric voltages at the ground can
cause severe electric shock.
¾Wait 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 life-
threatening risk of 󰘰re:
¾Jump away from the machine. Ensure a safe
stand when jumping. Do not touch the outside
of the machine.
¾Move 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:
¾Always make sure that the PTO-shaft guard
is in place and fully functional.
¾Make sure that the chosen rotary speed and
the sense of rotation of the propshaft or PTO-
shaft correspond with the permissible values
for the machine.
¾Make 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.
¾Shut down the PTO-shaft if the angles are too
large. The machine could become damaged.
Parts may be thrown o󰘯 and injure persons.
13

¾Switch o󰘯 the PTO-shaft if it is no longer
needed.
¾Ensure su󰘲cient overlapping of pro󰘰le tube
and PTO-shaft guard.
¾Allow PTO-shaft locks to click into place.
¾Secure the PTO-shaft guard with chains
against rotating.
¾Before assembly/disassembly of the prop-
shaft as well as before all interventions on
the machine:
Uncouple the PTO-shaft (shut o󰘯 from the

Use in the eld
DANGER
No passengers are allowed to ride on the
machine!
¾Observe the national legislation and regula-
tions on crop protection!
¾The personal protective out󰘰t stipulated in
the safety data sheets of the crop protection
agent manufacturers must be carried along
and worn during work.
¾Check the area immediately around the ma-
chine (for children!) before driving o󰘯 and
commissioning the machine. Ensure su󰘲cient
visibility.
¾Check the condition of the folding boom and
their mounting before use.
¾Ensure su󰘲cient stability of the machine in
case of longitudinal or transverse inclination
when working in uneven terrain. Pay attention
to the limiting values for the tractor.
¾Do not remove any of the mandatory and
supplied protective devices.
¾Stay clear of the operating range of hydrauli-
cally operated parts.
¾Use accessing aids and steps only at stand-
still.
¾At the headland reduce the travel speed and
disable spraying.
¾Excessive, jerky steering movements at the
beginning and the end of a curve will put ex-
treme loads on the folding boom.
¾The spraying agent may be blown away if the
droplets are 󰘰ne and the wind is strong. This
may cause damage to people and nature!
¾If the soil is very dry, the applied chemical can
be blown away together with dust and cause
damage. Ensure su󰘲cient moisture of the soil!
¾For tractors with cabins with ventilation fans
replace the fresh air 󰘰lters with activated-
carbon 󰘰lters! Observe notes and instructions
of the tractor manufacturer.
¾Ensure that the category of the tractor cabin
is approved for the respective crop protection
agent used.
¾Always ensure a su󰘲cient water supply in the
machine to be able to wash o󰘯 crop protection
agent in events of emergency.
¾Data 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.

Changing equipment / wear items
¾Only 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.
¾For 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.
¾Secure the machine against unintended roll-
ing away!
¾Secure raised frame parts you have to work
under with suitable supports!
¾Caution! Risk of injury caused by projecting
parts (e.g. folding boom parts)!
¾Assume 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.
¾Follow the speci󰘰cations 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.
¾Determine and provide the personal protective
out󰘰t as speci󰘰ed by the manufacturer of the
crop protection agent.
¾At 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 e󰘯ect on the
materials used in the crop protection sprayer.
¾Store all relevant information about the crop
protection agents used (safety data sheets,
instructions for use, etc.) in the document roll.
¾The water quality (the water hardness and
mineral content in particular) in󰘱uences the
property of some fertilisers and crop protec-
tion agents. Precipitation and de󰘱occulation
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!
¾Observe the data on compatibility of crop
protection agents with materials of the crop
protection sprayer!
¾Do not spray any crop protection agents that
have a tendency to agglutination or solidi󰘰ca-
tion!
¾Wear suitable protective clothing when han-
dling crop protection agents.
¾Do not eat, drink or smoke while handling crop
protection agents!
¾Keep crop protection equipment and crop
protection agents out of the reach of children!
¾Always ensure a su󰘲cient water supply in the
machine to be able to wash o󰘯 crop protection
agent in events of emergency.
¾In case of physical contact with crop protection
agents you may need to consult a physician.
¾Thoroughly clean hands and face after the
end of work.
¾Extended 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.
¾The application notes of the crop protection
agent manufacturers must be observed when
mixing di󰘯erent crop protection agents.

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.
¾Do not allow operating materials to drain out
into the environment.
¾Pick 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.
¾Do not 󰘰ll crop protection sprayers with water
from public bodies of water.
¾Filling 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!
¾Observe the national and country-speci󰘰c
regulations and standards (e.g. water protec-
tion areas).
Retrotting and
conversions
Structural changes not approved by HORSCH
may a󰘯ect the functionality and operational
safety of the machine and will void any warranty
claim.
