Read the operating manual carefully and follow the instructions
Initial operation of the machine must not take place before the opera-
ting manual has been read and understood. This particularly applies
to safety instructions.
Do not stand between the tractor and the machine
Standing between the tractor and the machine is especially prohibited
during coupling and uncoupling and when the motor is running. The
tractor must be additionally immobilised.
Riding on the machine is strictly prohibited
Do not transport people or objects on the machine. Riding on the ma-
chine is hazardous and strictly prohibited.
Proceed with great care in the event of leaking hydraulic fluid
Observe the corresponding safety instructions in the operating manu-
al.
Never remove the guards
Never open or remove the guards while the engine is running. Never
operate the machine without guards.
Stay clear of the slewing range
There is an acute risk of injury in the slewing range due to swivelling
or folding machine components.
Risk of crushing
Avoid the danger area. Gaps between components may become
smaller or disappear completely.
Retighten screws
After the first operating hours all screw must be checked and retighte-
ned, if needed. Vibrations might have loosened the screws.

Who is allowed to
operate the ma-
chine?
Only qualified personnel
Only qualified persons who have been informed of the dangers asso-
ciated with handling the machine are permitted to operate, service or
repair the machine. As a rule, such persons are trained and experi-
enced in agricultural work or have been thoroughly trained in a similar
fashion.
Coupling
Increased risk of injury
When coupling the machine to the tractor, there is an increased risk of
injury. Therefore:
•Secure the tractorin such away thatit cannot roll forwards or back-
wards
•The tractor and machine must belong to the same category
•Never stand between the tractor and the machine during coupling
•Actuate the three-point power lift system slowly and carefully
Nonobservance can lead to serious or fatal injury.
Only connect electric wires or cables after mounting the attach-
ment
The electrical supply must not be connected to the tractor when moun-
ting the lighting equipment. Short circuits and damage to the electro-
nics are possible.
Only connect hydraulics at zero pressure
Only connect the hydraulic hoses to the tractor hydraulic system if the
tractor and machine hydraulic system is depressurised. A hydraulic
system whichis under pressurecan cause unforeseen movements on
the machine.
High pressures in the hydraulic system
The hydraulicsystem is under high pressure. Regularly check all lines,
tubes and screwed connections for leaks and externally visible dama-
ge. Only use suitable agents when looking for leaks. Eliminate dama-
ge immediately. Escaping fluid may result in injuries and fires. Seek
medical attention immediately if injuries occur.
Colour-coded hydraulic hoses
To prevent operating errors, plug sockets and plugs for hydraulic con-
nections between the tractor and the machine must be identified by
different colours. Incorrectly connected hydraulic tubes can initiate un-
foreseen movements on the machine.

Safety
Centre of gravity
Observe the total weight, axle loads, tyre load-bearing capacity
and minimum ballast specifications
The front or rear attachment of machines must not cause the tractor's
permissible total weight, its permissible axle load or its tyre load-bea-
ring capacity to be exceeded. In order for steering capability to be
maintained, the front axle must bear at least 20 % of the tractor's em-
pty weight.
By investing some effort in making the calculations it is possible to de-
termine the:
•Gross weight
•Axle load
•Tyre load-bearing capacity and
•Minimum ballast
The following data is required to make this calculation:

Safety
Road transport
Make sure that the condition of the machine conforms to traffic
regulations
The machine must conform to current traffic regulations if you intend
to drive it on public roads. These include, for example:
•Lights, warning equipment and protective equipment are installed
•The permissible transport width and weight, axle loads, tyre load-
bearing capacity and total weights are observed
The driver and owner of the vehicle are liable if traffic regulations are
not observed.
Close the ball valves
If there are ball valves on the hydraulic lines or chassis cylinders, you
must close them prior to road transport. The accidental actuation of
control valves on the tractor might otherwise causemovements onthe
machine. This can result in damage to the machine or accidents.
Check remote cord for the quick release coupling
Remote cords must hang loose and must not, when in their lowered
position,release the couplings oftheir own accord. Coupled machines
might otherwise come loose from the three-point linkage of their own
accord.
Riding on the machine is strictly prohibited
Do not transport people or objects on the machine. Riding on the ma-
chine is hazardous and strictly prohibited.
Note the altered driving and braking performance
Driving and braking performance are altered when the machine is at-
tached to the tractor. Take the width and balancing weight of the ma-
chine into consideration, especially when cornering. A driving style
which not adjusted to the road conditions can lead to accidents.
Moderate your speed
Always adjust your driving speed to the road conditions. If conditions
are poor and your speed is too high, extremely high forces can arise
that place a major load on the tractor and machine and might over-
stress them. Travelling at an inappropriate speed can result in machi-
ne damage and accidents.
Putting the ma-
chine into opera-
tion
Initial operation after briefing
The machine must not be put into operation until the user has been
given proper initial instruction by an employee of the dealer, a factory
representative, or an employee of the manufacturer. Commissioning
without instruction can lead to damage to the machine due to false
operation or accidents can happen.
Ensure that the machine is in perfect working condition
Do not operate the machine unless it is in perfect working condition.
Check all important components and replace any defective compon-
ents before starting the machine. Defect components can cause da-
mage to equipment and injury to persons.

Safety
15
Do not remove the protective equipment
Protective equipment must not be removed or by-passed. Check all
protective equipmentbeforestarting themachine.Unprotected machi-
ne components can cause severe or fatal accidents.
Checking tyre pressures
Check tyre pressure regularly. If the tyre pressure is too high or too
low, this can reduce the service life of the tyre and result in undesira-
ble work results. Accidents might occur during road transport.
Riding on the machine is strictly prohibited
Do not transport people or objects on the machine. Riding on the ma-
chine is hazardous and strictly prohibited.
Height of machine and overhead power lines
If a height of 4.00 m is exceeded when folding the machine in and out,
the machine must not be folded in the vicinity of conducting overhead
power lines! Danger of electrocution! Should the machine come into
contact with an overhead power line:
•Do not attempt to climb out of the tractor cabin
•Do not touch any metal parts on the tractor
•Do not create any conductive contact with the ground
•Warn all persons in the area not to approach the tractor or the ma-
chine
•Wait for help from professional emergency service personnel as
power in the overhead line must first be switched off
Never climb onto the machine ifit is beneath conducting overhead po-
wer lines. The voltage can jump even if the lines are not actually tou-
ching the machine.
Make sure the immediate vicinity is clear
Before starting up, folding out the machine, and using it, check the
vicinity of the machine. Make sure the operator has an adequate view
of the work area. Do not begin work until the immediate vicinity is clea-
red of any persons or objects. Any use of the machine without verifi-
cation of the situation around it can lead to accidents.
Retighten all nuts, bolts and screws
Nuts, bolts and screws should be checked at regular intervals and
tightened if necessary. Screws can come loose unnoticed while ope-
rating. Damage can occur to the machine or injury to persons.
What to do in the event of a malfunction
In the event of a malfunction, shut down and secure the machine im-
mediately. The malfunction may be eliminated immediately, or your
dealer must be assigned the task. Further operation of the machine
can lead to damage to the machine or injury to persons.

Safety
Uncoupling the
machine
Increased risk of injury
There is an increased risk of injury when uncoupling the
machine from the tractor. Therefore:
•Secure the tractorin such away thatit cannot roll forwards or back-
wards
•Never stand between the tractor and the machine during uncou-
pling
•Actuate the three-point power lift system slowly and carefully
•Make sure the machine is standing on a secure and level surface
•Only disconnect the hydraulic hoses if there is no pressure in the
tractor and machine hydraulic system
Nonobservance can lead to serious or fatal injury.
Care and mainte-
nance
Follow the care and maintenance chart
Observe prescribed intervals for maintenance checks and inspections
specified in the operating manual. Nonobservance of the time periods
can lead to damage to the machine, poor quality of work or accidents.
Only use OEM replacement parts (original equipment manufac-
turers)
Many components have special characteristics which are essential for
the machine's stability and correct function. Only accessories and
spare parts supplied by the manufacturer have been tested and ap-
proved. Using other products may lead to malfunctions or impair safe-
ty. The use of non-OEM spare parts renders the manufacturer's gua-
rantee null and void and frees the manufacturer from all liability.
When performing care and maintenance work:
•Switch off the tractor's power take-off shaft
•Depressurise the hydraulic system
•Whenever possible, uncouple the tractor
•Make sure the machine is standing securely. Provide additional
support as required
•Do not use parts of the machine as climbing aids; use only special
and safe means of ascent
•Secure the tractor so that it cannot roll forwards or backwards
•Never reach into the V-belt while it is moving
It is only possible to guarantee work safety during care or mainte-
nance work through observing these regulations.
Turn off the electrical supply
Prior to carrying out work on the electrical system, disconnect it from
the power supply. Equipment under electrical power can cause dama-
ge to equipment and injury to persons.

Safety
17
Replace hydraulic hoses
Replace hydraulic tubes every three years. Hydraulic hoses can age
without any externally visible damage. Defect hydraulic lines can lead
to severe or fatal injuries.
Caution when cleaning with a high-pressure cleaner
The machine can be cleaned using either water or a steam jet. Only
use low pressure to clean bearings, fans, signal distribution boxes,
plastic parts and hydraulic tubes. Excessively high pressures can cau-
se damage to these parts.
Prior to welding work, disconnect the battery and generator
Prior to carrying out electrical welding work on the attached machine,
disconnect the tractor's battery and generator. This prevents damage
to the electrical system.
Tighten the screw connections
All screw connections released during maintenance and repair opera-
tions must now be retightened. Loose threaded connections can undo
without you noticing during your work. As a result, machine parts can
fall off. Severe injury to persons or damage to equipment can result.
Further regulati-
ons
Observe the regulations
In addition to these safety instructions, observe the following:
•Accident-prevention regulations
•Generally recognised safety regulations, occupational health re-
quirements and road traffic regulations
•Instructions given in this operating manual
•Operation, maintenance, and repair regulations

Range of applica-
tion of the ma-
chine
The Miniair Nova is a precision seed drill for seeding after seedbed
preparation. It is for normal use in agriculture. Versatile equipment op-
tions allow the seeding of round, calibrated seed. The prerequisite is
always a soil condition that allows cultivation and seeding. The level
of wetness or dryness, for example, can make seeding the soil impos-
sible with some soil types.
Proper use
Any application other than or beyond this, e.g. as a means of trans-
port, for stump pulling or to transfer power to other objects is conside-
red improper use. The manufacturer and dealer are not liable for da-
mage caused by improper use. The risk is borne solely by the user
Definitions
There are different interpretations and definitions for some agronomic
terms. The terms used in this operating manual are defined as follows.
Seeding after ploug-
hing
Seeding after completion of turning the soil with the plough.
Seeding after seed-
bed preparation
Seeding after completion of seedbed preparation or secondary prepa-
ration after turning the soil. The purpose of seedbed preparation is to
prepare the top soil layer for seeding. By working at a constant depth,
clods are crushed, the soil surface levelled and the ground below the
seed deposit is recompacted due to the soil contact required.
Mulch seeding
Seeding after completion of mixing the soil. The soil must be worked
deeper than the required deposit depth.
Direct seeding
Seeding without working the soil. Residue from the previous crop is
chaffed or in a condition that enables direct seeding.

19
Characteristics of
the machine
Perfect combination
Thanks to specially hardened material combined with an optimum de-
sign and high manufacturing quality, you acquire a reliable machine
for seeding. It is easy to handle and features low-maintenance mecha-
nics.
Exact depth adjustment and guidance
All sowing units can be adjusted exactly to the desired depth. The de-
posit depth can be adjusted via the front press wheels. The pre-run-
ning press wheels allow in combination with parallelogram construc-
tion of the sowing units a precise depth guidance.
Seed spacing and seed deposit
Even without tools, the seed spacing can be adjusted easily either
electronically or using a shift gear. The optoelectronics of the ma-
chinery is responsible for the monitoring of the grain deposit (acces-
sory). An intermediate press wheel beds the seed in an optimum man-
ner in the moisture-conducting soil layer. A seed coverercovers it with
loose earth and a press wheel firms up the ground which means that
it is better protected against mud formation.
