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.
¾ Do not exceed the permissible axle load, tyre
load bearing capacity and total weight, in order
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.
For road transport the machine must be set to
transport position. The machine must have been
folded up and secured, see chapter Folding and
Connecting and Transport position.
¾ Clean soil from the folding areas before fold-
ing up. Otherwise there could be damage to
the mechanics.
¾ If present: Secure the hydraulic cylinders on
undercarriage and drawbar in transport position against uncontrolled movements using
aluminium clips, see chapters Connecting and
Transport position.
¾ Assemble lighting, warning and protective
features and check the function.
¾ Before road travel clean the entire machine

¾ Consider the wide overhang and the centrifu-
gal mass of the implement as well as the lling
capacities, especially when cornering.
For transport on public roads, only drive
with empty seed hopper.
8
Pay attention to the permissible top
speed in accordance with the type approval for transport on public roads!
The specications 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, trac, sight and weather conditions.
Pay attention also to the notes in chapter
Commissioning!
The hydraulic cylinders on the undercar-
riage must be lled up with spacers, the
machine must be lowered on these spacers.
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.
Only use the machine with all protective features
and safety relevant installations, such as e.g.
detachable safety features, in place and fully
functional.
¾ Check nuts and bolts, especially the ones on
wheels and cultivation tools regularly for tight
t and retighten if necessary.
¾ Check tyre pressure regularly.
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
¾ Connecting features
¾ Protective features
¾ Lighting
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 coarse 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.
Coupling and unhitching
Faulty coupling of the machine and pulling tool
of the tractor causes dangers, which could result
in severe accidents.
¾ Caution with negative drawbar load!
With an empty hopper and under certain operating conditions the machine may have a
negative drawbar load.
The rear axle of the tractor is unloaded. This
has a negative eect on the steering and
braking characteristics.
Caution when unhitching!
Always fold the wings in or rest them on the
ground beforehand.
9
¾ Only park the machine on a rm and level sur-
face. Before unhitching the towed machine,
lower it to the ground. The machine could
otherwise strike up! The seed wagon could
tip backwards!
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 Secure the machine against rolling away.
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 hydraulic hoses to the tractor,
before both hydraulic systems on machine
and tractor are de-pressurised.
¾ Lower all hydraulically lifted parts (e.g. wings,
packer, undercarriage, etc.) to the ground
before performing 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 Hydraulic components on unsecured machine
parts must not be dismantled.
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 is equipped with pressure
accumulators.
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
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.
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. Turn the lever to the Road symbol
(pneumatic brake) before transport travel.
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.
10
Overhead lines
When unfolding or folding the wings, the machine may reach the height of overhead lines.
Possible voltage ashover to the machine causing fatal electric shock or re.
¾ Keep a safe distance to electric high voltage
power lines when unfolding or folding the
machine.
¾ Do not unfold or fold the wings in the vicinity
of pylons and power lines.
¾ With the wings unfolded 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.
What to do in case of voltage ashover
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.
Technical limiting values
If the technical limiting values of the machine are
not observed, the machine may get damaged.
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.
¾ Also pay attention to the max. permitted loads
for the tractor.

health of persons.
¾ Do not allow operating materials to drain out
into the environment.
¾ Take up drained operating materials with
absorbent material or sand, ll it into a leak
tight tank and dispose of in accordance with
statutory regulations.
Retrots
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

¾ Prior to working on the electrical system,
disconnect it from the electric current supply.
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 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 at electrical or electronic
components, bearings or the fan.
¾ When cleaning with high pressure cleaning
equipment or steam jet keep a distance of at
least 50 cm to machine components.
¾ Hopper, metering units, hoses and coulters
are contaminated with fertilisers and dressed
seed. Wear suitable protective outt when
cleaning. Avoid contact and do not breath
the exhaust air.
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 Do not clean new machines with a steam jet
of a high pressure cleaner. The paint takes
approx. 3 months to cure and could thus be
damaged if this time has not yet expired.
