1.0 INTRODUCTION
This Instruction Manual for Operation (hereafter called "the Manual") provides the operator with useful information on how to simplify
EQUIPMENT use by operating it correctly and in safe conditions.
The sections below must not be considered as a long and burdensome list of warnings: they must be regarded as a number of
instructions that improve machine performance and prevent damage to persons, objects or animals originating from incorrect
machine operation and use.
It is essential that each operator in charge of transporting, installing, commissioning, operating, maintaining, repairing and dismantling
the machine consults this manual and read it carefully before carrying out any operation. This will help him avoid incorrect manoeuvres
and prevent inconveniences that may jeopardise the machine integrity and eventually result in risks for operators' safety.
If you are still in doubt or have points to clear on machine operation after reading this manual, do not hesitate to contact the
Manufacturer who will be ready to assist you promptly and carefully for better and most efficient machine operation.
Finally, we would like to point out that existing regulations on safety, hygiene at work and environmental protection must always be
adhered to during all the phases of machine operation. The operator must therefore check that the machine be operated
exclusively in optimised safety conditions for both persons and objects.
This manual is to be considered as an integral part of the product. Therefore, along with the Declaration of Conformity, it must be
stored in a safe place where it can be consulted during the entire machine life and passed on to the new owner.
This manual was drawn up according to the regulations existing at the time when it was printed.
The Manufacturer reserves the right to change the machine without having to promptly update this manual. In the event of
disputes, the valid version is the Italian text.
Some of the pictures in this manual show details or accessories which may be different from those fitted in your machine. Components
or guards may have been removed to make images more useful.
1.1 GENERAL
Conventional symbols:
To identify and make different danger types recognisable, the following symbols are used in the manual:
WARNING!
DANGER FOR OPERATORS'
HEALTHAND SAFETY.
WARNING!
RISK OF DAMAGE TO MACHINE OR
DRILL PRODUCT.
In the text, symbols are accompanied by safety warning messages: these are short sentences to further exemplify the type of risk/
danger. Warning texts guarantee the safety of operators and prevent damage to the machine or drill product.
The drawings, pictures and diagrams in this manual are not scaled. They exemplify the information provided in the text and are an
addition to it: they are not meant to illustrate the supplied machine in details. For a more comprehensive overview of the machine,
drawings, pictures and diagrams represent the machine, or parts of it, without the protections or guards in most cases.
Finally, a few words on annexes. As they are photocopies of catalogues, drawings, etc., they have the original ID and page numbers
(when provided with it). If they are not originally provided with a numbering, they are not given one.

Tractor hitch
1) Hook the equipment to a suitable, sufficiently-powered tractor
by means of the appropriate device (lifter), in conformity with
applicable standards.
2) The class of the equipment attachment pins must be the
same as that of the lifter attachment.
3) Take care when working within the range of the lifting arms
as this is a very dangerous area.
4) Be very careful when hooking and unhooking the equipment.
5) It is absolutely forbidden to stand between the tractor and
linkage for manoeuvring the lifting controls from the outside
(Fig. 3).
6) It is absolutely forbidden to stand in the space between the
tractor and the equipment (Fig. 3) with the engine running.
It is possible to work between the tractor and the equipment
only after the parking brake has been applied and a suitably
sized blocking wedge or stone has been placed under the
wheels.
7) The attaching of additional equipment onto the tractor brings
about a different distribution of weight on the axles. Check
the compatibility of the tractor performance with the weight
that the machine transfers onto the three-point linkage. If in
doubt consult the tractor Manufacturer.
8) Comply with the maximum admissible weight for the axle,
the total mobile weight, transport regulations and the highway
code.
Transport on Road
1) When driving on public roads, be sure to follow the highway
code of the country involved.
2) Any transport accessories must be provided with suitable
signs and guards.
3) It is very important to remember that road holding capacity as
well as direction and braking capacity can be influenced,
sometimes con-siderably, by equipment being either carried
or towed.
4) To work in safety the instructions given in the highway code
should be followed; these prescribe that at least 20% of the
weight of the tractor alone should be borne by the front axle
and that the weight on the arms of the hoist should not be
more than 30% of the weight of the tractor itself.
5) When negotiating curves, be aware of the variation in
centrifugal force exerted in a position other than that of the
center of gravity, with and without the equipment in tow. Also
pay greater attention on sloping roads or ground.
6) For transport, adjust and fasten the lateral lifting arm chains
of the tractor; check that the seed and fertilizer hopper covers
are closed properly; lock the hydraulic lifting control lever.
7) All road transport must only be carried out with the tanks and
tanks empty and at max speed of 25 km/h. For the transport
on the road it must be assured the cover with the appropriate
one pulling of coupling (A, Fig. 4). Periodically, it is necessary
to verify the degree of deterioration of pulling and to the
occurrence to replace it.
8) For displacements beyond the work area, the equipment
must be placed in the transportation position.
9) Upon request the Manufacturer will supply supports and
tables for signaling of dimensions.
10) When the dimensions of carried or partially-carried equipment
conceal the tractor’s signalling and lighting devices, these
must also be installed on the equipment itself, in conformity
with regulations of the highway code of the country involved.
When in operation make sure that the lighting system is in
perfect working order. The transport on the road must be
done with light (B, Fig. 4) turned off. The orientation of the
light (C, Fig. 4) must be done in conformity with regulations
of the highway code of the country involved.

Safety measures concerning the hydraulics
1) At the moment of connecting the hydraulic tubes to the
hydraulic system of the tractor, make sure that the hydraulic
systems of the operating machine and the tractor are not
under pressure.
2) For the operative hydraulic connections between tractor and
operating machine, the sockets and plugs should be marked
with colours to distinguish them, to avoid them being used
wrongly. There would be a danger of accident if the
connections were to be swapped round.
3) The hydraulic system is under high pressure; because of
the accident risk, when searching for leakage points special
auxiliary instruments should be used.
4) Not to never carry out the search losses with the fingers or
the hands. The liquids that exit from the holes can be nearly
not visible.
5) During transport by road the hydraulic connections between
tractor and operating machine should be disconnected and
secured to the support provided.
6) Do not use vegetable oils under any circumstance. These
could cause a risk of damage to the cylinder gaskets.
7) The operating pressures of the hydraulic system should be
between 100 bars and 180 bars.
8) Never exceed the indicated hydraulic system pressure levels.
9) Check that the quick hook-ups are coupled correctly; parts of
the system could get damaged if they are not.
10) Oil escaping at high pressure can cause skin injury with the
risk of serious wounds and infection. Call a doctor
immediately if such an incident occurs. If the oil with surgical
means is not removed quickly, can take place serious
allergies and/or infections. Therefore, the installation of
hydraulic components in the tractor driver's cab is strictly
forbidden. All the components of the system should be
positioned carefully to avoid parts being damage during use
of the equipment.
11) In case of participation on the hydraulic system, to unload
the hydraulic pressure carrying all the hydraulic commandos
in all the positions some times after to have extinguished the
motor.
Maintenance in safety
During work and maintenance operations, use suitable perso-
nal protection gear:
Overalls Gloves Shoes Goggles Hardhat
1) Do not proceed with maintenance and cleaning if the power
take-off has not been disconnected first, the engine power
off, the hand brake pulled and the tractor blocked with a
wooden block or stone of the right size under the wheels.
2) Periodically check that the bolts and nuts are tight, and if
necessary tighten them again. For this it would be advisable
to use a torque wrench, respecting the values of 53 Nm for
M10 bolts, resistance class 8.8, and 150 Nm for M14 bolts
resistance class 8.8 (Table 2).
3) During assembling, main-tenance, cleaning, fitting, etc., with
the machine raised, place adequate supports under the
equipment as a precaution.
4) The spare parts must correspond to the manufacturer’s
specifications. Use only original spares.

3.4 DOSER
The doser (Fig. 7) the most important part for distribution, is
located underneath the seed (fertilizer) hopper.
It is driven by an electric motor connected to the tractor speed
sensor.
In that event, for the metering operation and the metering
adjustment, checking and tests, please refer to the relevant User
and Maintenance Booklet.
The volumetric distributing device, is essentially composed of
four elements for seeds distribution:
A) aluminium monobloc frame;
B) agitator element;
C) dosing rollers;
D) feeler pin.
MONOBLOC FRAME
The monobloc frame is made of aluminium and offers the
following main advantages:
- realization of very high precision and high quality over time;
- resistance to the effects of UV rays or to the problems of harsh
autside temperatures;
- high resistance to corrosion;
- quick simple maintenance: in a few minutes we can completely
remove the components of the doser without fully unscrewing
the screws, using just one spanner.
AGITATOR ELEMENT
Guarantee of continuous feeding to the dosing rollers. The
agitator can be disabled by simply removing the drive belt. To
disable the agitator, lift the round belt above the edge of the drive
pulley (Fig. 8) and, on the opposite side, rotate the dosing roller
in the driving direction. The belt will come off (Fig. 11).
(To fit the belt, see chapter on dosing roller)
DOSING ROLLERS (Fig. 9)
- Large diameter to reduce the number of revolutions and avoid
seed load losses;
- High number of cells arranged in a steggered pattern to
guarantee uninterrupted delivery;
Assembling and disassembling the dosing roller
All the dosing rollers are compact units constructed in a single
block (except for the fine seeds dosing roller, yellow).
Never fit dosing rollers with screws loosening the handwheel!
The radial precision of the wheels, which are calibrated after
assembly, could be damaged!
WARNING
Always use gloves: after calibration, the new dosing rollers
could have sharp edges that might injure the operator!
There are various types of wheels for a wide range of applications,
in 4 different product families (Fig. 9):
C1) 5 wheels, 8 chambers per wheel, (mod. G1000 - red).
Normal seeds distribution over 200 Kg/Ha.
C2) 5 wheels, 16 chambers per wheel (mod. N500 - green).
Normal seeds distribution up to 200 Kg/Ha.
C3) 5 wheels, 32 chambers per wheel, (mod. F25-125 - yellow)
Fine seeds distribution.
C4) 2 wheels, 8 chambers per wheel, (mod. G1002 - red).
Fertilizer distribution.
Use a suitable metering roller with the type of distributed seeds.

Replacing the DOSING ROLLER
Perform this operation while the dosing chamber is empty:
A) Empty hopper;
B) Hopper with product: use the movable panel (P, Fig. 7) to
exclude feeding from the hopper to the doser. Then empty
the dosing chamber.
1) Remove the belt from the agitator and fully disconnect the
metering roller transmission (Fig. 8).
2) Take out the bearing support of the metering roller (G, Fig.
10);
3) Take the metering roller out sideways (H, Fig. 10) ...
To re-assemble, follow the steps in reverse order.
IMPORTANT: before starting seeding, open the panel (P, Fig. 7)
to feed the doser.
FEELER PIN
The feeler unit may also be easily disassembled in a single block in a matter of minutes for cleaning purposes. It consists of 5 single
hatches that are spring-loaded to ensure tight closing. The hatches do not touch the seeding wheel while it is in operation! Thanks
to the separators fixed between one hatch and the next, it is possible to activate each element independently of the others. Moreover,
the separators are shaped in such as way as to act as a shield against foreign bodies that could damage the dosing roller. The
hatches are adjustable, and their shape has been specifically designed to adapt to the seeds.
WARNING
Always use gloves. The new parts especially might have sharp edges that could injure the operator!
1) In order to disassemble the feeler unit, loosen the four nuts of the axles (front and back) (Fig. 11), using a 13 mm spanner ...
2) until it is becomes possible to push out the discs fitted inside, remove them from their seats (Fig. 12) and move the axles.
3) Remove the back part (Fig. 13) of the feeler pin unit, first, followed by the front part.
When the hatch is disassembled, it is also possible to remove the emptying hatch, by
sliding it out from below.
On completion of cleaning, re-assemble the unit by following the above mentioned
steps in reverse order, taking care to position the flat parts of the axles correctly! Put the
feeler pin unit in place. Then slide the washers back in their housing and finally tighten
the nuts by hand.
Once the hatch has been mounted, the elements must be mobile. To check that they
are, simply push them with your fingers (Fig. 14). If they do not move, it is advisable to
disassemble them and clean them.
During re-assembly, before tightening the various parts, ensure that the rear part of
the hatch (on the spring side) is not too high. Install the dosing roller in order to
ensure that the height is correct.

CLEANING SPRING ELEMENTS (SEEDS)
Cleaning spring elements (A, Fig. 15) are used during the
distribution of oily seeds by means of the yellow seeding roller,
mod. F25-125.
The main action of these spring elements is keeping the
chambers of the seeding roller clear so that seed distribution is
regular and constant.
The shaft of the cleaning spring elements is positioned outside
the seed dosing chamber.
When other types of seeds are being distributed, disengage the
cleaning spring elements to avoid undesired wear:
… loosen the knob (B, Fig. 15), remove the levers (C) from their
housing and move them in the direction shown by the arrow.
Wear
When the oil layer is thick, spring elements wear out quite quickly
and they are no longer efficient.
Wear can be easily checked from the outside.
Replacing the spring elements
1) Loosen and remove the knob (B, Fig. 15). Then, move the
lever (C) in the direction shown by the arrow.
2) Extract the seeding roller (Fig. 16) as shown and described
previously.
3) Loosen the M8 nuts (Fig. 17) using the supplied multi-purpose
wrench.
4) Extract the shaft of the spring elements from its housing (Fig.
18).
5) Use the supplied multi-purpose wrench and an Allen wrench
(no. 3) to loosen the fastening screws of the spring elements
as shown in Figure 19.
6) Replace the spring element using genuine spare parts. Then,
assemble the unit back repeating the procedure above in a
reversed sequence.

DISTRIBUTION OF FINE SEEDS
Distribution of quantities lower than 3 kg/ha.
During the dosing test the number of gearbox revolutions is low
because the quantity of product to be distributed is small. This
can result in irregular distribution of the product. If the operator
notes this, he should follow the instructions below.
Considering that every section (A, Fig. 20) of the dosing roller
distributes 20% of the product contained in roller itself, the number
of operating sections can be increase and the gearbox rotation
speed to reduce to obtain more homogeneous distribution.
First, take the dosing roller off the machine. Then, unscrew the
knob (B, Fig. 20) using the supplied wrench and remove the lock
nut (C). Extract the section(s) to be activated and put them back in
their positions (1-2-3-4-5, Fig. 20) turning them by 180°.
When re-assembling the sections, make sure that during
operation the dosing grooves of the active sections are staggered
from one another (D, Fig. 20). This will give continuity to
distribution.
Re-position the lock nut, tighten the knob using the supplied
wrench and assemble the roller back on the machine.
Block the cleaning element in the operating position and make
sure that the springs hook the previously excluded sections (E,
Fig. 20) preventing their rotation and consequently distribution.
Carrying out the dosing test. To rotate the dosing devices, follow
the instructions provided in the Operation and Maintenance
Manual of the Electrical Distribution Control, and make sure that
the real number of operating sections is coherent with the 1
section roller.
To start distribution again using some of the sections or all of
them disassemble the roller and its parts and put them back in
their original position.
