3. SAFETY RULES
3.1 General safety rules:
• It is mandatory to read and follow the instructions for the use and maintenance
manual before carrying out any operation or move with the shredder.
• Improper use or an incorrect move may seriously damage things and people.
• Both the operator and the maintenance fitter must know the shredder well,
especially regarding dangers resulting from improper use or incorrect repairs.
• Before starting, checks on tractor and shredder, must be carried out as regards:
functionality, road safety, accident prevention rules.
• Even when using the shredder correctly, stones or other objects may be thrown a
long distance. Therefore nobody must stand within the danger area. Special
attention must be paid when working near roads or buildings.
• Use tractor with cabs.
• The condition of flails and of all guards must be checked before beginning the
daily work - they must be replaced if damaged or missing.
• During checks or repairs, make sure nobody could start the shredder by mistake,
• Never wear loose or fluttering clothes.
• Never carry passengers on the tractor.
• Never carry passengers on the shredder.
• Never connect the power takeoff with the engine running.
• Never approach the shredder until the rotor has completely stopped.
• Do not enter the working zone of the PTO shaft. It is dangerous to approach the
rotating parts of the machine.
• Keep the PTO shaft guard in good order.
• Before starting check the surrounding area for the likely presence of children
and/or animals.
• Do not stand in the range of the operation of the machine.
• The PTO shaft must be assembled and disassembled only with the engine stopped
and the starting key removed.
• Before connecting the power takeoff, check that the speed and the rotational
direction correspond to those of the shredder.
• Before leaving the tractor with the tool attached, proceed as follows:
1. Disconnect the power takeoff,
2. Put the machine steadily on the ground (with the hydraulic lift)
3. Apply the hand brake and, if the ground is steeply sloping, wedge the tractor.
4. Take out the starting key.
• Immediately replace any safety sign, or any missing or damaged decal.
3.2 Safety Rules concerning Road Traffic
• In transport, reduce speed, especially on bumpy roads. The very weight of the
shredder may render driving difficult and damage the shredder itself.
• Check moreover that the levers that operate the hydraulic lift are locked, to avoid
the lowering of the machine during transport.
• When driving on public roads, respect all road rules in force.
• Never transport the shredder with the rotor moving, even for short distances.

3.3 Safety Rules during use
• Pay special attention when working with the machine, not to touch fixed objects,
such as road drain, walls, shafts, kerbs, guard rails, tracks etc. This could cause the
breakage of the flails, which would be thrown at very high speed.
• If wires, ropes or chains should get entangled in the rotor, stop immediately, to
prevent damage or dangerous situations; stop the rotor and the tractor, take out the
starting key. Put working gloves on, clear the rotor with the aid of pliers or shears.
Do not try to disentangle by inverting the rotational direction of the rotor.
• Do not use the machine when there is vibration in the flail head, as this would
cause breakage and serious damage. Find the cause of the vibration and eliminate
it.

Adjust the two tractor lower linkage stabilizers (3) thus fixing the machine to the
tractor in a central position.
• Proceed in reverse order to detach the shredder from the tractor.
4.4 Fitting the PTO shaft
• Following the Instructions in 4.3 assemble the PTO shaft (6) and check that the
overlap is not less than 2/3 of L. Be sure to keep a 4 cm backlash (see illustration
above) if it needs shortening, proceed as shown below (see illustration).
• The guards of the PTO shaft must be fixed to the machine and to the tractor with
chains, to prevent rotation. The minimum overlap of the guard and the PTO shaft
must not be less than 5 cm. (see illustration below).

11
4.5 Tractor stability
Due to the design of the mowers and the work they do, it is essential to ensure tractor
stability, in order to eliminate any risk of imbalance or overturning.
• Lift the machine and check that the tractor does not mount up. In case it does,
ballast the rear wheel of the tractor opposite to the extended machine and at the
front of the tractor (see illustration below).
4.6 Parking
• Park the machine in a safe place, on flat and firm ground in order to prevent the
risk of rolling over.
• Lower the shredder to the ground with the aid of the hydraulic lift of the tractor.
(see illustration below).

5. ADJUSTMENT AND SETTING UP
5.1 Adjustment
Adjustment of the height of cut is obtained by shifting the flail head roller in order to
suit the material to be cut and the required degree of chopping (see illustration
below).
IMPORTANT: Flails must never touch the ground.
6. USE AND OPERATING RULES
6.1 Starting
Before using the shredder check the tightness of all bolts and the integrity of all
guards. Check that the number of revolutions and the rotational direction of the
power takeoff of the tractor correspond to those required by the machine see decal on
the gearbox (see page 9). Engage the power takeoff at low engine RPM to avoid
damaging the transmission gearbox and belts.
6.2 Working mode
• Adjust the machine to suit the type of work to be done and the material to be cut:
adjust the height of cut, as shown (see illustration above).
• Working speed is chosen to suit the material to be cut and the degree of chopping
required. The optimum speed ranges from 3 to 8 km per hour.
6.3 Side shift - Non-hydraulic models
IMPORTANT: if you want to move the machine from the central to side position
proceed as follows:
• Unscrew the connecting bow.
• Bore the holes on marked points. (upper cover already has got the holes).
• Put the connecting bow on the new position.
• Tighten the screws.

7. MACHINE MAINTENANCE
All maintenance, cleaning and repair operations must be carried out with the shredder
firmly lowered to the ground and detached from the tractor, or with disconnected
PTO, and the tractor engine switched off and starting key out.
After the first two hours operation from new (or after fitting new belts) check belt
tension.
Regularly and after every 8 hours of machine operation:
• Tighten bolts and nuts.
• Check wear and condition of flails.
• Check the safety guards.
• Check belt condition.
• Visually check the frame to detect possible damage caused by earlier work.
• Check gearbox and extension lubricating levels.
• Grease the parts indicated on the appropriate decal. (see below).
This operation must be always carried out at the end of each working day. This
facilitates the removal of mud or other material from the rotating parts (bearing, pins
etc.) in order to avoid rust and possible seizure.
• Every 100 hours operation grease the moving parts of the PTO shaft, extracting
the two parts of the shaft.
• After long inactivity, repeat the operation before re-using the machine.
• Use grease classification DIN 51825 (KR 2 K)
• For gearbox use compatible oils - classification ISO VG 220
