Introduction
Foreword
Before operating the machine, read and strictly
comply with the operating instructions. In doing
so, you will avoid accidents, reduce repair costs
and downtime and increase the reliability and
service life of your machine. Pay attention to
the safety instructions!
HORSCH will not assume liability for any
damage or malfunctions resulting from failure to
comply with the operating instructions.
These operating instructions will assist you in
getting to know your machine and in using it
correctly for its intended purposes.
The operating instructions must be read and
strictly adhered to by all persons working on or
with the machine e.g.:
¾Operation (including preparation, fault
recti󰘰cation during work and servicing)
¾Maintenance (maintenance and inspection)
¾Transport
Together with the operating instructions, you
also receive receipt. Field service technicians
will instruct you in the operation and care of
your machine. After this you should return the
machine registration form to HORSCH. This
con󰘰rms your formal acceptance receipt of the
machine. The warranty period starts with the
date of delivery.
We reserve the right to alter illustrations as
well as technical data and weights contained in
these operating instructions for the purpose of
improving the machine.
Warranty claims
Warranty claim forms must be submitted through
your local HORSCH dealer to the HORSCH
Service Department in Schwandorf.
Only claims, which have been correctly completed
and submitted no later than four weeks after the
defect occurred, can be processed.
Please return damaged components cleaned
and emptied to HORSCH within 4 weeks
together with a warranty claim form and precise
fault description.
Exchange parts, which do not require the old
part to be returned. Please keep such parts for
12 weeks, until a decision has been made on
the action to be taken.
Warranty repairs, which are to be carried out by
a third-party company, or which are expected
to take longer than 10 working hours, must be
agreed upon in advance with the Customer
Service Department.

Intended use
The drill is state-of-the-art and designed in ac-
cordance with relevant, recognised safety reg-
ulations. However, risks of injury to the operator
or third parties and impairment of the machine
or other tangible assets can occur during use.
The machine must only be operated for its in-
tended use if in a technically perfect condition,
whilst being aware of safety and risks and in
strict compliance with the operating instructions!
Faults, particularly those which impair safety,
must be remedied immediately.
The machine must only be operated, serviced
and repaired by persons who are familiar with
it and have been made aware of the dangers
involved.
Genuine spare parts and accessories from
HORSCH have been specially designed for this
machine.
Spare parts and accessories which are not de-
livered by us, have not been tested or approved
by us.
Installation or use of non-original HORSCH
products may have a detrimental effect on
speci󰘰c design features of the machine and
impair the safety of machine operators and the
machine itself.
HORSCH will not assume liability whatsoever for
damage resulting from the use of non-original
parts and accessories.
The drill is designed for the placement of seeds
and fertilisers. Any other use beyond these
limits, e.g. as a means of transport, is deemed
improper.
HORSCH will not assume liability whatsoever
for damage resulting from unintended use. The
risk will be borne solely by the user.
The respective accident prevention regulations
and other generally recognised safety-related,
occupational medical and road tra󰘲c regulations
are to be adhered to.
Intended use also includes the strict compliance
with the operating instructions and adherence to
the operating, maintenance and repair instruc-
tions speci󰘰ed by the manufacturer.
Consequential damage
The machine has been manufactured by
HORSCH with great care. Nevertheless, even
when used properly, deviations or complete
failure in the placing quantity may be caused,
e.g. by:
¾di󰘯erences in the composition of seed or
fertiliser (i.e. grain size distribution, density,
geometrical shape, dressing, sealing).
¾Blockages or seed bridging (i.e. caused by
foreign bodies, non-smooth seeds, sticky
dressing, moist fertiliser).
¾Worn wearing parts (e.g. metering unit).
¾Damage caused by external in󰘱uences.
¾incorrect drive motor speeds and driving
speeds.
¾incorrect setting of the unit (incorrect connec-
tion, non-observance of setting tables).
Therefore, it is crucial to always check your
machine before and during operation for correct
operation and adequate application accuracy.
Compensation claims for damages which have
not been caused by the machine, are excluded.
This also includes that any liability for conse-
quential damages caused by drill and control
commands, is excluded.

In these operating instructions
The operating instructions distinguish between
three di󰘯erent types of warning and safety in-
structions. The following graphic symbols are
used:
important notes!
if there is a risk of injury!
if there is a risk to life and limb!
It is important that all the safety instructions
contained in these operating instructions and
all the warning signs on the machine are read
thoroughly
Ensure that the warning signs are in a legible
and replace and signs that are missing or dam-
aged.
These instructions must be followed in order
to prevent accidents. Inform other users of the
warnings and safety instructions.
Do not carry out any operations which may a󰘯ect
the safe use of the machine.
Retrots
In case of retro󰘰ts, extensions to equipment and
functions, strict compliance with country speci󰘰c
regulations concerning weights, weight distribu-
tion and dimensions is mandatory.
For equipment in󰘱uencing the weight or weight
distribution one must check and comply with the
regulations concerning towing facilities, support
and axle loads.
For machines without brakes a brake system
may need to be retro󰘰tted, if the permissible
weight limits are exceeded.
In case of changes concerning data mentioned
on the type plate, a new type plate with updated
data must be attached.
Authorised operators
Only those persons who have been authorised
and instructed by the operator may operate the
machine. Operators must be at least 16 years
of age.
The operator must hold a valid driving licence.
He is responsible for third parties in the oper-
ating area.
The person in charge must
¾make the operating instructions available to
the operator.
¾Ensure that the operator has read and under-
stood the operating instructions.
The operating instructions are a component part
of the machine.
Protective clothing
For operation and maintenance you need:
¾snug 󰘰tting clothing
¾safety gloves to protect against sharp-edged
machine parts.
¾hearing protection
¾safety goggles to protect the eyes against
dust or spray, when working with fertiliser or
liquid fertiliser (follow the instructions of the
fertiliser manufacturer).
¾when handling dressing or dressed seed
wear a respirator mask and safety gloves
(follow the instructions of the dressing agent
manufacturer).

Operational safety
The machine must only be put into operation
after receiving instructions by employees of the
authorized dealer or a HORSCH employee. The
machine registration form has to be completed
and returned to HORSCH.
In addition to the operating instructions, it is
important to observe the accident prevention
regulations speci󰘰ed by agricultural trade as-
sociations!
All protective features and safety equipment,
such as detachable protective devices, must be
correctly in place and reliably functioning before
the machine is put into operation.
¾Check nuts and bolts, especially the ones on
wheels and cultivation tools regularly for tight
󰘰t and retighten if necessary.
¾In case of malfunctions immediately stop and
secure the machine.
¾Check tyre pressure regularly.
Caution with negative tongue load
With an empty hopper and under cer-
tain operating conditions the machine
may have a negative tongue load.
The rear axle of the tractor is unloaded. This has
a negative e󰘯ect on the steering and braking
characteristics.
Care must also be taken when unhitching.
Always fold the wings up before or rest the wings
on the ground.
Road trafc safety
The valid road tra󰘲c regulations are to be ob-
served when travelling on public roads, paths
and areas.
Observe permissible transport widths and
heights.
Assemble lighting, warning and protective equip-
ment and check the function.
Do not exceed the permissible axle loads, tyre
carrying capacities and total weights, in order
to ensure su󰘲cient steering and braking capa-
bilities.
The front axle must be loaded with at least 20
% of the tractor weight.
Handling is a󰘯ected by the connected equip-
ment. It is important to take into account the
large overhang and the centrifugal mass of the
implement, particularly when cornering.
For road transport the machine has to be con-
verted to transport position.
The machine must be folded up and secured.
Pay special attention to the transporta-
tion height when passing under bridges
and low suspended power lines.
Clean soil from the folding areas before folding
up. Otherwise there could be damage to the
mechanics.
Clean all soil o󰘯 the machine before driving on
public roads.
Passengers are strictly forbidden to ride on the
machine!
When transporting with a maximum speed of
25 km/h only drive with a empty seed hopper.
With road transport approval you must only
travel at the speed specied in the type ap-
proval.

Accident prevention
In addition to the operating instructions, it is
important to observe the accident prevention
regulations speci󰘰ed by agricultural trade as-
sociations!
Hitching / un-hitching
There is risk of injury to persons when hitching/
un-hitching the machine to the drawbar of the
tractor.
¾Secure the machine against rolling away.
¾Take special care when reversing the tractor.
Never stand between tractor and machine.
¾Only park the machine on a 󰘰rm and level
surface. Before unhitching the machine, lower
it to the ground. The drawbar could otherwise
strike up.
The seed wagon could otherwise tip
back and damage hopper or machine.
Brake system
Depending on the equipment, the machines can
be equipped with a pneumatic or a hydraulic
service brake system.
For road transportation the brake system must
always be connected and fully functional.
After hitching the machine and before transpor-
tation you should always check the function and
condition of the brake system.
The adjustable brake power controller must be
set to “partial load”, even when the hopper is
empty.
For road travel the hopper must be
empty.
On the hydraulic system
¾Do not connect hydraulic hoses to the tractor,
before both hydraulic systems on machine
and tractor are de-pressurised.
¾The hydraulic system is under high pressure.
Check all lines, hoses and screwed con-
nections regularly for leaks and any visible
external damage!
¾Only use appropriate aids when checking for
leaks. Repair any damage immediately! Oil
sprays can cause injuries and 󰘰re!
¾In the case of injury, contact a doctor imme-
diately!
Power sockets and connectors on the hydraulic
connections between the tractor and machine
should be colour-coded in order to exclude op-
erating errors.
The control unit on the tractor must be
secured or locked when not in use or
when the machine is in transport posi-
tion, in order to prevent accidents
caused by unintended hydraulic move-
ments or movements caused by per-
sons other than the operator (children,
passengers).

14
Changing implements
¾Secure the machine against unintended
rolling!
¾Secure lifted frame parts, under which you will
be working, with suitable supports!
¾Caution! Danger of injury caused by protrud-
ing parts!
¾Do not use press rollers or other rotating parts
to climb onto the machine. These could start
to rotate and you could fall and be seriously
injured.
In operation
¾Check the area around the machine (for chil-
dren!) before setting o󰘯 and starting operation
of the machine. Ensure su󰘲cient visibility.
¾Do not remove any of the mandatory and
supplied protective devices.
¾Stay clear of the operating range of hydrauli-
cally operated parts.
¾Only use ascending aids and steps when ma-
chine is at standstill. Passengers are not al-
lowed to ride on the machine during operation!
Do not reverse with the machine low-
ered. The components have only been
designed for forward travel in the 󰘰eld
and may be damaged when reversing.
Service and maintenance
¾Ensure that regular tests and inspections are
always carried out to schedule, as speci󰘰ed
in the operating instructions.
¾Prior to performing maintenance and servicing
work, ensure that the machine is positioned
on 󰘰rm, level ground and that it is properly
secured against rolling away.
¾De-pressurise the hydraulic system and lower
or support the implement.
¾Before cleaning the machine with high pres-
sure cleaning equipment cover all openings,
which should stay clear of water, steam or
cleaning agents for reasons of safety or op-
eration. Do not aim the water jet directly at
electrical or electronic components, bearings
or the fan.
¾After cleaning, check all hydraulic lines for
leaks and loose connections.
¾Check hoses for cha󰘰ng and signs of other
damage. Remedy any faults immediately!
¾Prior to working on the electrical system,
disconnect it from the electric power supply.
¾When 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.
¾When cleaning with high pressure or steam
cleaning equipment keep a distance of at least
50 cm to machine components.
¾Re-tighten screwed connections which have
been loosened during servicing and mainte-
nance work.
Do not wash new machines with a
steam-jet or high-pressure cleaner. The
paint takes approx. 3 months to cure
and could thus be damaged if this time
has not yet expired.
