system must be used.
• Any unauthorized modification to this machine will void the warranty.
• Correct use of the machine, careful observance of the stated rules and strict application of all
precautions to prevent possible dangerous situations will reduce the risk of personal injury or
accidents, and it will allow the machine to work better and longer and reduce errors to a
minimum.
ATTENTION
• Make sure that there are no large stones, large tree stumps, other foreign material of any
kind (cables, pipes, chains, etc.) in the work area before operating the flail mower.
• Observe and carefully apply the instructions for adjusting the height of the machine from the
ground, and avoid other people standing within a range of 50 meters who are not operating the
machine.
• It is recommended that you never work on wet grounds as this can compromise the
performance and balancing of the machine, which also risks damaging the rotor.
Noise level
• The noise test has indicated a sound pressure level LAeq corresponding to 84 dB (A) x 1 dB
measured in an open field at a distance of 3 m. from the machine and at 1.6 m. in the
working area, in continuous maximum permissible working conditions.
• According to this information, it is recommended to wear individual ear protection. WARNING:
Always wear hearing protection when operating the machine.
Storage
If the machine is not used for a long time, it is necessary to store it in a protected place and to
avoid dust accumulation. Before storage, we recommend cleaning the entire machine carefully
and applying oil to moving parts to protect them from rust.
5
Before storing the machine for a long time, we recommend the following procedure:
• Wash the machine carefully
• Make a general check of the machine to locate possible structural lesions, note possible deep
darkening of the painting, verify that the original safety labels are present in their correct
position, that they are complete and legible
• Lubricate all moving parts, e.g. the tension bolts, the connecting shaft to the PTO
• If possible, wrap the machine in a covered room and place the machine on wooden boards on a
level
surface
The used oil must not be dispersed in the environment, because according to the effective legal
provisions it is
classified as special waste and as such it must be given to the special collection centre.

hydraulic pipes every 5 years.
• When the machine is not connected to the power supply, the hydraulic
pipes must be connected to the special supports.
WARNING!
Never stand between the flail mower and the tractor!
WARNING!
Make sure the flail mower is completely stationary before approaching it.
Long-term use of the machine can cause the engine and the belts on the
hydraulic system to become very hot. DO NOT touch these parts during or
immediately after operating the machine.
Any changes to the machine may cause problems. In that case, the user is
solely responsible for any accidents.

Connection to
tractor
3. Operation
Behavior on the road, steering and braking capacity are affected when the machine is connected to
the tractor. The front axle of the tractor lights up in relation to the weight attached to the coupling to
the lifting arm: the load on the front axle must be at least 20% of the weight of the empty tractor.
Before connecting the machine to the 3-point connection, the tractor's safety device must be
positioned to make it impossible for unwanted and/or casual lifting and lowering. The three-point
connection of the tractor and the machine must match or be adjusted.
In the rod zone of the tractor's rear lights, there is a risk of injury due to pinching and cutting
points.
Do not use the external control to lift the machine.
In the transport position, the side stop of the rod and the control level of the lift are
blocked. Connection
WARNING
Always use the recommended safety equipment (safety shoes, work gloves and hearing protection)
Mounting the flail mower:
The machine is equipped with bolts for the tractor's three-point connection. Connecting the
machine to the tractor is done as follows:
• Approach the tractor to allow the lifting beams to coincide with the 3 point joint and connect
them with the relevant bolts
WARNING
Insert safety plugs into the holes. Make sure they are blocked.
• Connect the 3-point link to the upper link and adjust it to position the machine parallel to the
ground. Check that the blades or hammers on the rotor shaft, when the machine is on the
ground, do not touch the ground during rotation.
• To prevent the knives or hammers from touching the ground, it is necessary to regulate the
height of the rear roller via the blocking screw which is inserted into the selected hole.
WARNING
Place the tractor on a level surface. Before adjusting the flail mower, stop the engine and lock the
brake.
Hydraulic connection of lateral displacement
• Turn off the engine (if on), apply the parking brake and remove the ignition key from the ignition
panel.
• Check that there is no pressure in the tractor's hydraulic system.
• Connect the quick-coupling hydraulic pipes to the tractor after checking that all joints are
clean and in very good condition.
• Pressurize the hydraulic system. Check that it is not leaking and that the connection is correct.
• When the flail mower is finished operating, the hydraulic pipes released from the tractor must
be fixed in the corresponding supports for this purpose.
10
WARNING
Before connecting/disconnecting the hydraulic pipes, the engine of the tractor must be stopped.
Before connecting, turn off the hydraulic lines, stop the tractor engine and set both sensors in the
control levels to allow the oil to flow from the system.
Operating information
WARNING
Before operating the machine, make sure that there are no people within 70 meters of the machine.
Before exiting the tractor and during any maintenance operation, apply the parking brake, turn off
the engine and remove the ignition key from the ignition panel. Wait for all parts to stop
completely.
For a good result, we recommend working with a forward speed of 2.5 km/h on the grass round
and 2.0 km/h on crop residues.
During work, you must not make curves with the machine to the ground or work in the opposite
direction. Always lift the flail mower for changes of direction and curves and insert the power
supply first. During use, the flail mower can give way to dust emissions, in which case you are
working on dry ground. We recommend using tractors equipped with cabs with filters on the fan
system or using a suitable system to protect the respiratory tract, such as Dust masks or masks
with filter.
4. Maintenance
In the event of a breakdown, the user must stop operation immediately, turn off the engine and
remove the ignition key, and exit the tractor to investigate the problem. Only start operation again
when the cause of the breakdown has been found and resolved.
It is recommended that all maintenance operations be carried out by qualified and trained personnel
persons, with the machine disconnected from the tractor.
It is necessary to check daily the state of wear of the knives, hammers and their connection points.
If they are very worn or damaged, they are replaced immediately as their breakage can cause
dangerous protrusions of the components.
Front protection bar
The protective beams must always be in good condition to avoid possible throwing of materials
into the front zone.
Immediately replace such parts if bent or otherwise damaged. To replace the beams:
• Unscrew the screw on the left side of the machine and grab the fixing bolts
• Replace the damaged beams Use only original spare parts.
11
General maintenance
Carry out maintenance on the machine when it is disconnected from the tractor and placed on a
level
surface.
For any maintenance work, adjustment and cleaning must be carried out with the machine
standing on the ground, with the tractor's engine switched off, the power disconnected, the
handbrake pulled and the ignition key removed from the start panel.
The belt tension is checked every 4 hours of work. You must always be aware of its voltage.
WARNING
Perform maintenance only when the tractor engine is turned off and the power is removed, the
ignition key is removed and wait until all parts have come to a complete stop.
Adjusting the straps
Loosen screws A and B that block the support shaft and loosen the coin nut C Loosen the screws
that lock the gearbox on the support shaft D
Every 4 hours of work:
• Check the condition of the nuts
• Lubricate with lithium oil when indicated by the GREASE symbol
After 50 hours of work:
• Select the correct amount of oil in the transmission and fill to level using oil type SAE 90 EP
API GL4
Every 100 hours of work:
• Select the correct amount of oil in the transmission and fill to level
