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
Conventionalsymbols:
To identify and make different danger types recognisable, the following symbols are used in the manual:
WARNING!
DANGERFOR OPERATORS'
HEALTHANDSAFETY.
WARNING!
RISKOF DAMAGETO MACHINEOR
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 carriedor 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 fertilizer hopper.
Motive power is transmitted to it by the drive wheel through
gears (with ratios proportional to the width of the work to be
carried out) and chains.
The Electric Distribution Control can be supplied as an
accessory. 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, GRINTA, is essentially
composed of four elements for ferilizer distribution:
A) aluminium monobloc frame;
B) agitator element;
C) dosing rollers;
D) Feeler pin.
MONOBLOCFRAME
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.
AGITATORELEMENT
Guarantee of continuous feeding to the dosing rollers.
The agitator has a diameter of 85 mm and consists of 4 elements (curved pins). If the agitator is running too fast, its mixing effect can
be halved, by removing the two center pins (B, Fig. 7).
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.
- Simply leave the belt on the drive shaft (Fig. 9).

Assembling and disassembling the dosing roller
All the dosing rollers are compact units constructed in a single block.
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!
As described above, remove the round belt
of the agitator, then screw the handwheel
to the side of the dosing roller (Fig. 11) and
proceed when the machine is completely
empty. Once the fastening knob of the
dosing roller has been released, it remains
connected to the doser casing, in order to
safeguard against it being accidentally lost.
Slide the dosing roller out sideways (Fig.
12) and remove it from the doser (Fig. 13).
To re-assemble, follow the steps in reverse
order.

FEELERPIN
The feeler pin 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 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 fertilizer.
ATTENZIONE
Utilizzare sempre i guanti di protezione. Soprattutto le parti nuove potrebbero pre-
sentare bordi appuntiti e provocare ferite all'operatore!
1) In order to disassemble the feeler unit, loosen the four nuts of the axles (front and
back) (Fig. 17), using a 13 mm spanner....
2) until it is becomes possible to push out the discs fitted inside, remove them from
their seats (Fig. 18) and move the axles.
3) Remove the back part (Fig. 19) of the feeler pin unit, first, followed by the front part
(Fig. 20).

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! Once the hatch has been fitted, slide in the discs and reposition them in their seats. At this stage,
simple screw the hatch into place. Tighten the screws well 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. 21).
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
thehatch (on the spring side) is nottoo high. Install the dosing roller inorder to ensure
that the height is correct.

3.5 OLEO-DYNAMIC BLOWER DRIVE
Safety
The equipment is suitable only for the use indicated. Any use
other than that described in these instructions can cause
damage to the machine and constitute a serious danger to the
user.
Regular operation depends on the correct use and adequate
maintenanceof the equipment. It is advisable therefore to observe
scrupulously what is described in order to prevent any
inconveniences that could prejudicate proper operation and
duration. It is just as important to keep to what is described in
this booklet since the Manufacturer declines all responsibility
due to negligence and non-observance of these rules.
At any rate the Manufacturer is available to assure immediate
and accurate technical assistance and all that may be necessary
for the improved operation and better performance of the
equipment.
The oleo-dynamic blower drive may be used, maintained and
repaired only by personnel with complete knowledge of the
apparatus in question and of the relative dangers. Check the
correct connection of the quick-couplings; failure to do so could
result in damage to the system. Disconnect the oleo-dynamic
unions only after having first depressurized them.
ATTENTION
High-pressure oil leaks can cause serious skin injuries with the
risk of infection. In such cases seek immediate medical attention.
It follows that oleo-dynamic components should not under any
circumstances be installed in the tractor cabin.
All the component parts of the pressurised system should be
carefully installed in order to avoid damage during the use of the
machinery.
There are two types of oleo-dynamic system for the blower drive:
a) dependent system: connected to the tractor’s system.
b) independent system: a system with a self-contained oleo-
dynamic system.
3.5.1DEPENDENT SYSTEM
Characteristics of the tractor necessary for installation
-A sufficient number of distributors on the tractor: the supply
to the blower drive has maximum priority.
-Tractor oil flow rate: the oil required for engaging the blower is
approx. 32 litres/minute with a max. pressure of 150 bar.
- For correct blower operation and sufficient oil cooling we
recommend supplying the circuit with an amount of oil equal to
55÷60 litres.
-Oil cooling: if the tractor is not equipped with a large enough
cooling system, it will be necessary:
a) to install one;
b) increase the oil reserve by means of a supplementary tank
(ratio:1:2 between thepump delivery/minute andthe oil reserve).
- The return circuit must be low pressure (max 10 bar).
- Do not connect the return circuit to the auxiliary distributor.
- Tractors: check the tractor according to the above observations.
If necessary have any modifications carried out by the tractor
dealer.
- Oil supply: follow the data of the table in Fig. 30.
WORKINGDESCRIPTION
The oil flow necessary to drive the blower, is taken from the
tractor distributor, through a pressure tube to a three-way
regulator. The rotational speed of the oleo-dynamic motor, and
therefore that of the blower, is proportional to the flow pressure
shown on the manometer (Table 4). The system is equipped
with a safety valve that allows the blower to continue turning by
inertia even after the system has been disengaged or when
there has been a sudden failure of the system.
The return circuit, which can have a radiator incorporated (on
request), must be low pressure (max 10 bar) otherwise the oil-
seal of the oleo-dynamic motor will be damaged. We recommend
that a 3/4 inch return pipe is connected to the tractor’s oleo-
dynamic system scavenge union in the following way:
a) The return oil must pass through the filter;
b) The return oil must not pass through the distributors but
through a low-pressure return circuit (scavenge);
For further information contact the manufacturer of the tractor.
STARTINGUP
With the engine off and the tractor immobilized, connect correctly
all the quick-couplings. Start the engine and operate the system
at idle for a few minutes bringing constant pressure to the entire
circuit in order to avoid instability of the blower. It is possible to
regulate the pressure only when the oil has reached the right
temperature and the blower does not present changes of speed.
If the equipment is used with more than one tractor and,
consequently, different distributors and oils, it will be necessary
to repeat the calibration procedure for each tractor.
In tractors with variable-delivery pumps (closed hydraulic circuit),
fitted with an oil delivery regulator, first open the three-way
regulator «B» completely and, starting with little oil pressure,
open the internal regulator gradually until the pressure required
is reached. This is indicated on the pressure gauge «C» (see
paragraph 3.5.3).
