2. GENERAL DESCRIPTION OF THE MACHINE
ATTENTION!
Where the shredder is delivered packaged, the elements of the packaging
must not be left discarded as potential sources of risk. Remove the above
to the appropriate collection places if they are contaminants and/or biode-
gradable.
Fig. 1
Shredder MA
Fig. 2
Lifting unit
- 3 arms
The shredder series MA, ML, MP consist of a body of steel that supports all
the parts of the machine; it is designed in such a way as to ensure perfect
working of the product without the need for high powers, in compliance with
the applicable safety standards.
The articulation is secured to the main frame that allows the machine to
be tilted; two arms are connected to the joint for lateral movement, and the
three-point connection is attached to the arms.
The machine is able to perform rotations with respect to the ground of 65°
and 90° by means of a hydraulic control, operated exclusively on board the
tractor; in addition the shredder, via the hydraulic control arms can perform
lateral movements.
Within the body is housed the rotor supported by high strength bearings and
driven by transmission belts that take motion from the side transfer of the
box to the gears or revolution multiplier. The rotor is dynamically balanced
for homogeneous rotation without vibration.
The number of knives or hammers with which the rotor is equipped guaran-
tee perfect shredding of the material and adequate ventilation.

At the time of purchase the shredder is as shown in Fig. 1, and is designed
to be installed on the rear of the tractor that will need to be !tted with a "uni-
versal" rear hydraulic 3-point lift unit, second category, for the models MA,
ML and third category for the mod. MP suitable to withstand the weight and
absorption characteristics of the shredder.
The hitch is shown in Fig. 2

6. UNLOADING AND UNPACKING
Unloading of the shredder must be performed with the utmost attention by
the operators in order to avoid damage to the machine and damage to the
operators themselves.
ATTENTION!
Ensure that during the loading and unloading operations and during move-
ment of the machine, there are no unauthorised persons in the area of op-
erations.
Unloading from the means of transport must be performed by means of
suitable lift trucks or cranes suitable for the purpose. It is mandatory to use
lifting straps or chains that are suitable and "EC" approved
ATTENTION!
Check that the load capacity of these means is adequate for the weight of
the machine to be lifted. The weight is shown on the machine identification
label (Cap. 4.1).
ATTENTION!
The means of transport must allow perfect positioning of the machines,
which should rest with the base on the loading platform of the means and
should also not be overlapping. This could cause deformation of the struc-
ture of the machine.

7. INSTALLATION OF THE MACHINE
7.1 Application to the tractor
As the lift bars of each tractor have their own length, it is necessary to de-
termine for each machine the suitable position for the cutter, lengthening
or shortening the bar of the upper attachment of the tractor (Fig. 13), and if
necessary shorten the cardan shaft according to the instructions in chapter
7.4.
The connection of the tractor to the shredder must be performed as in !gure
14-15 -16-17.
The shredder models MA and ML are applicable to tractors equipped with
universal three-point attachment (Fig. 2) of 1° and 2° category, while the MP
is applicable to tractors with 2° and 3° category attachments.
ATTENTION!
Do not stand between the tractor and the shredder during the opera-
tions of engagement.
PERFORM CONNECTION AS FOLLOWS:
1) Draw in the bars of the hitch, positioning them within the attachment
points of the shredder.
2) Insert the lift rods into the pins of the shredder and lock them with the
appropriate snap pins (Fig. 14-15).
3) Insert the cardan shaft ensuring that it is perfectly locked.
4) Lock the bars on the hitch with the relevant chains and parallel tension-
ers.

7.4 Adaptation of the cardan shaft
The cardan shaft supplied with the shredder is of standard length; it is there-
fore necessary to adapt it to the tractor that will be used. For this contact an
authorised workshop.
1) Remove the shaft in two halves, applying one part to the PTO in the trac-
tor and the other to the PTO in the shredder. Raise and lower the hydraulic
lift to !nd the minimum length of sliding and indicate it on the shaft.
2) Cut the outer plastic tube of length exceeding more than 30 mm, and the
inner tube with the same size (Fig.20); then re!t with care ensuring that the
articulation forks are coplanar.
3) Activate the hitch, and check that sliding of the cardan takes place hap-
pen without contrasts and that a minimum part of overlap of the tubes re-
mains that is not less than 100mm.
4) ATTENTION! Check the length of the cardan joint at each change of the
tractor.
5) The end of the cardan provided with torque limiter and possible free
wheel will be mounted on the PTO of the shredder.
6) The maximum angle of the cardan permitted is 15° (Fig. 21).
7) Attach chains supplied to the cardan at the fixed points in order to avoid
rotation of the guards.
8) Lubricate the cardan following the manufacturer's instructions (see
instruction and maintenance manual cardan shaft).

8. RULES FOR USE OF THE SHREDDER
The application of additional apparatus to the tractor involves an imbalance
of the weights on the axles. It is advisable to balance, as far as possible, the
weights by adding ballast, on the front of the tractor.
The ballast required can be calculated using the formula below (Fig. 22).
i= wheelbase
d = distance between the front axis and the ballasts
S1 Distance between centre of the rear axle and centre of the lower
connection points
S2 Distance between the centre of the lower connection points and
barycentre of the arm of the milling machine
T = weight of the tractor + 75Kg (operator)
Z = weight of the ballast
M = weight of the machine
Before starting the work of shredding check the follow-
ing points:
a) verify engagement of the safety chain of the cardan shaft;
b) ensure that the machine is parallel to the ground and is
also resting on the ground (Fig. 26);
c) Check all the safety devices of the shredder.
e) ensure that no other person is in the vicinity of the work-
ing area of the shredder (Fig.24);
e) engage the PTO slowly and accelerate the tractor, avoid-
ing exceeding the maximum limit of rotation of the PTO of
540 rpm/min (Fig. 23).
ATTENTION!
The equipment applied can be operated exclusively through the cardan
shaft complete with the necessary safety guards against overloads and
equipped with its !xed protection with appropriate chain.
