ØConsider your personal abilities, carriage way, traffic, sight and weather condi-
tions.
2.6 Safety in operation
2.6.1 Commissioning
The operational safety of the machine cannot be guaranteed without orderly per-
formed commissioning. This can lead to accidents with severe or even fatal physical
injuries.
ØThe machine must only be put into operation after receiving instructions by
employees of the authorized dealer or a HORSCH employee.
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.
ØCheck nuts and bolts, especially the ones on wheels and cultivation tools regu-
larly for tight fit and retighten if necessary.
ØCheck the tyre pressure at regular intervals, see maintenance overview.
2.6.2 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:
• Hydraulics
• Brakes (if available)
• Connecting features
• Protective features
• Lighting
If in doubt about the safety-relevant status of the machine, e.g. in case of leaking
operating fluids, visible damage or unexpected changes in driving behaviour:
ØImmediately shut down and secure the machine.
ØIf possible, locate and rectify the faults by following these operating instruc-
tions.
ØRectify possible causes for damage (e.g. remove coarse dirt and tighten loose
screws).

fied by a qualified expert workshop.

2 | Safety and responsibility
14 60026387 • 01 • 03/2021 • en
2.6.3 Hitching and uncoupling
Faulty coupling of the machine to the pulling tool of the tractor causes dangers,
which could result in severe accidents.
ØStrictly comply with all operating instructions:
• These operating instructions
• Operating instructions of the tractor
ØExercise special caution when reversing the tractor. Never stand between
tractor and machine.
ØOnly park the machine on a firm and level surface. Before unhitching the
towed machine, lower it to the ground.
ØSecure the machine against rolling away.
2.6.4 Hydraulics
The hydraulic system is under high pressure.
The machine's hydraulics has several functions, which can cause injury to persons or
damage to the machine if operated incorrectly:
• Escaping fluid may penetrate the skin.
• Hydraulically supported machine parts may drop.
• Hydraulic components may be flung away. Pressurised hydraulic hoses may whip
about when detaching them.
ØConnect the hydraulic hoses to the tractor only when the hydraulics on tractor
and machine are depressurised.
ØLower 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.
ØThe hydraulic system is under high pressure. Check all lines, hoses and screwed
connections regularly for leaks and any visible external damage!
ØUse only appropriate means when searching for leaks. Repair any damage im-
mediately! Oil sprays can cause burns and fire!
ØPower sockets and connectors on the hydraulic connections should be marked
in order to exclude operating errors.
ØIn the event of injury, consult a doctor immediately.
ØSecure and lock the control unit on the tractor if not in use!
ØReplace hydraulic hoses at the latest after six years, see Maintenance overview.
ØTo prevent unintentional machine movements due to air trapped in the hy-
draulic cylinders these cylinders must already be filled with hydraulic oil before
installing them in the machine. The cylinder and hose assembly are then bled
by retracting and extending the cylinder several times.
2.6.5 Brake system
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.
1. After coupling the machine and before transportation check the function and
condition of the brake system.
2. If available, check the setting on the brake pressure regulator.
3. Always release the parking brake before starting to drive.

Safety and responsibility | 2
60026387 • 01 • 03/2021 • en 15
4. Before unhitching the machine secure it against rolling away and apply the
parking brake.
2.6.6 Propshaft / PTO-shaft
Persons can be caught, pulled in and seriously injured by the rotating PTO-shaft or
propshaft.
Before switching on the PTO-shaft:
ØMake sure that the PTO-shaft guard is in place and functional.
ØMake sure that the chosen rotary speed and the sense of rotation of the prop-
shaft or PTO-shaft correspond with the permissible values for the machine.
ØMake sure that no persons are inside the danger zone around the PTO-shaft or
propshaft. Never switch on or couple the PTO-shaft while the tractor motor is
shut down.
ØShut down the PTO-shaft if the angles are too large. The machine could be-
come damaged.
ØSwitch off the PTO-shaft if it is no longer needed. Assemble the protective fea-
tures and establish their protective position.
ØEnsure sufficient overlapping of profile tube and PTO-shaft guard.
ØAllow PTO-shaft locks to click into place.
ØSecure the PTO-shaft guard with chains against rotating.
ØBefore assembly/disassembly of the propshaft as well as before all interven-
tions on the machine: Uncouple the PTO-shaft (shut off from the tractor cab),
switch off the tractor engine, pull off the ignition key and wait until all parts
have come to a standstill.
ØFollow the operating instructions for the propshaft.
2.6.7 Overhead lines
When unfolding or folding in the wings, the machine may reach the height of over-
head lines. Possible voltage flashover to the machine may cause fatal electric shock
or fire.
ØKeep a safe distance to electric high voltage power lines with the wings folded
and when unfolding or folding in the wings.
ØDo not unfold or fold in the wings in the vicinity of pylons and power lines.
ØNever leave or access the machine under overhead lines to avoid possible risks
of electric shock or voltage flashover.
What to do in case of
voltage flashover
Voltage flashover generates high electric voltages on the outside of the machine.
This results in extreme voltage differences 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).
1. Do not leave the cabin.
2. Do not touch any metal objects.
3. Do not create a conductive connection to ground.
4. Warn persons: DO NOT come near the machine. Electric voltages at the
ground can cause severe electric shock.
5. Wait for professional rescuers. The overhead power line needs to be switched
off.

2 | Safety and responsibility
16 60026387 • 01 • 03/2021 • en
If persons need to leave the cabin despite the voltage flashover, e.g. in case of a po-
tential life-threatening risk of fire:
6. Jump away from the machine. Ensure a safe stand when jumping. Do not
touch the outside of the machine.
7. Move away from the machine with short stepping strides.
2.6.8 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
• Maximum speed
See chapter Technical data, Type plate and Type approval.
ØAlso pay attention to the maximum loads for the tractor.
2.6.9 Use in the field
DANGER
No passengers are allowed to ride on the machine!
ØOperate the machine only in reliable weather conditions.
ØCheck the area immediately around the machine (for children!) before driving
off and commissioning the machine. Ensure sufficient visibility.
ØCheck the condition of the cultivation tools and their mounting before use.
ØDriving stability may be affected in the following situations, especially when
cornering: Driving at accelerated speed, along the contour line toward the
slope and on uneven terrain with longitudinal and lateral incline. Ensure suffi-
cient stability of the machine. Pay attention to the limiting values for the
tractor.
ØDriving stability may be affected when using auxiliary equipment or, if permit-
ted, driving with filled seed hopper. Ensure sufficient stability of the machine.
Pay attention to the limiting values for the tractor.
ØDo not remove any of the prescribed and supplied protective devices.
ØStay clear of the operating range of hydraulically operated parts.
ØDo not drive backwards with the machine lowered. The components have only
been designed for forward travel in the field and may be damaged when re-
versing.
2.7 Changing equipment / wear items
ØOnly pulling tools may be attached that meet the technical requirements ac-
cording to these operating instructions. HORSCH does not assume any liability
for damages resulting from the attachment of non-fitting pulling tools as well
as incorrect mounting.

Safety and responsibility | 2
60026387 • 01 • 03/2021 • en 17
ØFor 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.
ØSecure the machine against unintended rolling away!
ØSecure raised frame parts under which persons will be present with suitable
supports!
ØCaution! Danger of injury caused by projecting parts (e.g. coulters)!
ØAssume ergonomic working postures with any assembly work.
ØDo not step on rotating parts when climbing onto the machine. They may spin
and create the danger of very serious injuries from falling.
2.8 Fertiliser and dressed seed
Inappropriate handling of fertiliser and dressed seed can cause poisoning and death.

2.11 Spare parts
Genuine spare parts and accessories from HORSCH have been specially designed for
this machine.
Spare parts and accessories which are not delivered by us have not been tested or
approved by us.
The installation or use of other than HORSCH products can therefore negatively af-
fect the design characteristics of the machine and thus impair the safety of man and
machine.
HORSCH will not assume liability whatsoever for damage resulting from the use of
non-original parts and accessories.
If the component to be replaced is marked with a safety sticker, these stickers must
also be ordered and attached to the spare part.
2.12 Care and maintenance
Inappropriate care and maintenance put the operational safety of the machine at
risk. This can lead to accidents with severe or even fatal physical injuries.
ØConform to prescribed schedules for repetitive tests or inspections.
ØService the machine according to the maintenance plan, see chapter Care and
maintenance.
ØOnly perform the work described in these operating instructions.
ØBefore starting maintenance and service work park the machine on level and
firm ground and secure it against rolling away.
ØDepressurise the hydraulic system and lower or support the implement.
ØPrior to working on the electrical system, disconnect it from the electric cur-
rent supply.
ØWhen performing welding work on the machine, disconnect the cables from
electronic components. The ground connection must be as close as possible to
the welding point.
ØBefore cleaning the machine with high pressure 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 or bearings. When cleaning with high-pressure cleaning equip-
ment or steam jet always keep a distance of at least 50cm to machine com-
ponents.
ØAfter cleaning, check all hydraulic lines for leaks and loose connections.
ØCheck for chafing and signs of damage. Remedy any faults immediately!
ØRetighten screw connections loosened for care and maintenance work.
ØDo 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.
ØDanger of explosion! Do not exceed the specified tire pressure, see Mainten-
ance overview.
NOTE
