Intended use
FLY MOWER Triple and foldable lawnmower B. is suited for cutting grass and wood residues up to max. 6-7 cm.
Position of the operator
During transport and work operations, the operator will have to start the machine by means of the drive of the tractor.

Description
These models are transported by the tractor by means of a three-point attachment, and they act on the ground by virtue
of their weight and PTO rotation. The structure consist of a working unit made up of a horizontal axis rotor to which all
the contoured tools are connected which rotate at a greater speed than that of advance. In this way the product is laun-
ched from inside the structure towards the external wall, it moves upwards and comes out of the rear part. The machine
has a working height regulation system obtained by means of lateral slides or by wheels or by the rear roller; thereby
creating a uniform layer of processed product on the ground.
The PTO shaft consist of a single-side clutch (free wheel) which permits motion transmission in only one direction,
freeing the PTO of the tractor in the release stage. The tools, called hammer cutters are normally made up of blades, but
hoes, hammer blades or other can be used instead.

Safety precautions
Warning!
The following instructions cannot completely safeguard anyone operating the machine from all dangers that might occur. They
should be combined with common sense and experience, which are totally indispensable measures for the prevention of accidents.

• The operator must ensure that the machine is always maintained clean from any extraneous materials, debris, tools, oil etc.
• The machine should be cleaned after each use. During this operation the machine should be stopped and in a stable position
with the ignition keys of the tractor taken out so as to prevent any possibility of anyone causing it to move.

• When compressed air or water is used for cleaning purposes protective goggles and mask must be worn and other person or
animals must be kept well away from the vicinity of the machine.
• Do not use ammable liquids.

• At the end of the cleaning session a check should be made for wear and tear, damaged or badly xed parts.

• Check the state of wear on exible tubing.

• The manual should always be at hand so that it may be consulted to check the correct operative cycle every time a doubt may
arise.
• If this manual is lost or damaged, you will need to ask OMARV for a replacement copy.

• Structural damage, improper modications, alterations or repairs can change the capacity of production of the machine, the-
reby cancelling this certication.
• Any modication should be made exclusively by technicians of the OMARV or the authorised sales network.
• This machine is usually tted on the rear of the tractor. It will therefore be necessary to add extra weight to the front of the
tractor to prevent the risk of tipping over.

• Always drive slowly especially on irregular ground to prevent loss of balance.On turning take sucient care bearing in mind the
load and movement of the machine on the axle of the tractor.

• Ensure that the guards of the power drive are in place and provide for spares in case of damage.

• Never transport the machine with the rotor blade in motion.

• These machines may, in certain conditions, throw shredded material and other object gathered from the ground for great di-
stances, which can cause serious injury or even death to anyone in the projectile path of the machine. It will therefore be neces-
sary to block the shredding operation if there are people around either moving or static within 100 meters of the machine.
• When the height of the vegetation to be mown prevents the visibility of foreign objects, the mowing should rst be made at
intermediate height in order to allow for an inspection of the ground and the removal of foreign object allowing for a further cut
at the desired height.
• This pre-emptive action will, moreover, notably reduce wear and tear on the machine.
• Avoid the blades coming into contact with bulky objects.
• Do not climb onto the tractor or the machine while they moving. Avoid contract with tyres while they are in motion. Climb on
or off the tractor only when it is completely still and the ignition key is taken out. On no account should anyone climb onto the
machine itself.
• Do not use the machine if there is an oil leak present.
• Do not search out a leak with bare hands. Use protective gloves and a piece of material or cardboard. Oil under pressure can
penetrate under the skin and cause gangrene. In the event of this happening seek urgent specialist medical attention.
• Carefully read and respect the manufacturer’s instructions when using oil, solvent, detergents or other chemical substances.

Checks to be carried out on the tractor
• Ensure that the drive shaft is tted correctly both on the power drive of the tractor and on the universal shaft of the machine.
• Check that the universal shaft is exposed for at last 1/3 third of the thread in its most extended position.
• Ensure that the guards are in perfect order, that they can be moved freely and that the xing chains are not under strain when
themachine is fully raised or lowered.

• Check that in the position of continuous working, universal shaft does not make an angle greater than 20° against the align-
ment of the power drive of the tractor.
• Ensure that the drive shaft does not touch the guard of the power drive of the tractor, the guards of the transmission shafts or
other parts of the machine.
• No operation regarding the drive shaft or the power drive should be made with the tractor motor running. The ignition key
should be taken out and shaft of the power drive should be in the off position.

• As soon as the shredding operation is nished the drive shaft must be disengaged from the power drive of the tractor and
returned to the support supplied for it.

• During use, maintenance, repairs, on the road, or during delivery of the machine the operator must wear safety footwear, safety
gloves, safety helmet and safety goggles for protection from falling objects or materials projected from the normal working of
the machine.

• The operator’s clothes should be as close tting as possible. Never use wide or oppy clothing.
• Never allow inexperienced or untrained person to use the machine. All use of the machine must be carried out slowly to avoid
carelessness that might create space that is free from any obstacles.

• Negligence or lack of attention could endanger your safety.
• Objects such as ropes, wire, cables, chains etc can hook onto the rotating elements of the cutting mechanism and be thrown
out at high speed causing very dangerous situations for the safety of the operator. You should avoid the blades coming into
contact with such object.
• If wire or similar materials become wrapped around the rotor try to free up the rotor (wearing safety gloves) with the help of
shears. Do not try to carry out the job by inverting the direction of rotation.
• Take great care during shredding on sloping ground. The machine could sway and make the tractor lose its balance, causing
serious injury or death to the operator. If this should happen do not remain in the vicinity and do not allow anyone to remain in
the rotation or oscillation zone of the machine.

• Check that there is nobody in the oscillation area of the machine before starting to rotor or the potential enacting of hydraulic
displacement.

• Do not allow anybody to climb onto the tractor or onto the machine. Do not carry out any operation if there is anyone nearby or
on the machine. Do not allow anyone to come near especially not children.

• Check the machine periodically inspecting the bolts in general, worn or broken parts, pinched or broken cables loose con-
nections or connections with too much play. Ensure that all the joint pins are adequately blocked. Always keep the machine
scrupulously clean and free form foreign objects. Clean immediately, any stains of oil or any other inammable material, to avoid
danger of re.

• Serious injury can be caused by neglecting maintenance.

• Do not continue to use the machine if a cutter is lost or so badly worn as to cause vibration. Consult the relevant section of the
manual for instruction on replacement procedures.

• Always replacement both the worn blade and the one opposite to it at the same time.

BOLOGNA - FLY MOWER

• Always select the rotor stop position before unthreading the drive shaft from a power drive on a tractor or a completely
independent power drive.

• Make a daily check on nuts, bolts, exible and other xture system. Checking for potential defect, alignment, or breakage
that may prejudice the safety of the machine. If you do nd any such problem you should immediately take measures to
make repairs or replacements.
• Any maintenance, repair or checking operation must be carried out with the machine completely still and isolated from the
power drive of the tractor. The ignition key must be taken out. Always position the machine on points or blocks when such
procedures are carried out in order to prevent any potential lowering or raising of the tractor.

• INSTALLATION AND FUNCTION
Lifting
For the lifting of the machine during the cargo operations and I unload the means
of transport with which Mother or any other move is delivered by the House for which does not use the all-purpose tractor to
itself, to use exclusively the indicated point and the curlew.
For the move mediated equipment of lifting,
been veried that his lifting ability is
adjusted to the weight of the machine.
“Warning!
When the machine has been raised at a superior height to the 50
¼¼ the workers must remain rigorously over a certainty distance
the perimetre of same superior to 2 metres. A breaking of the system of lifting
or they constitute an uncontrolled movement in fact a serious danger for the safety of the staff. During the move of the components
whose dimensions do not allow sufcient visibility it is advisable to do use from more operators to supply the indications.
Before moving the package, verifying that the system of elevation and the relative equipment (ropes, ropes, hooks and so on) are
adjusted by the cargo. To verify the stability of the package before proceeding to the lifting. The ropes must be sufciently long to
allow the lifting of the machine while the shelters are do not speeded up. Possible solicitations might compromise the precision of the
machine. The staff not suited the works must not stop at the area been interested in the move.
The machine and all the his components must be stored to the covered one and é absolutely forbidden to position above of them
other cases or varied materials.”
Before enlivening the machine always to verify the weights and the general indications brought back on the package.
When a moving takes place with a system of adequate lifting, to raise the cargo of 200 mm from land and slewing to back. In
raising the cargoes, taking into account the height of the environment in which it is worked.
Before starting the movement been veried that the passage area is moves and that you are not mobile objects on board

or other protections (rags or wood).
“Warning!
In case the machine must be moved at the place in which it has been positioned in origin it will be needed to contact the technicians
of the Omarv to have all that indispensable information to be able to carry the following move operations out
in conditions of certainty. The transport, the lifting and the unloading of the installation have always to second is carried out
current prescriptions and staff trained (for example station vendors, crane operators) that are wanted to use the individual protective
means put to their disposition.”
I carry on road
In case of circulation on public roads to keep to the current Road Code.
Considerateness!
To make the transport on road the machine will must always to be in
position closed like visible in gure, with the stem of relieved support,
the hydraulic pipes inserted into the position of rest, the cardanic tree
correctly blocked and the electric connection of the lights
back connected with the all-purpose tractor.
During the transport on road it will be needed to take into account that:
• the behaviour of the all-purpose tractor can be compromised at the mass of the towed tool;
• during a turning, the machine covers the curve with a ray of sharp turn more closed compared to the all-purpose tractor;
• the machine can occupy a superior width to that one of the all-purpose tractor, then go out of his shape;
• if the shape of the machine was turning out to be wider than that one of the all-purpose tractor, it is needed to apply on the
back of the machine a bar with lights of back signalling;
• the machine can turn out to be more unstable than the all-purpose tractor, especially on disconnected grounds;

• Insert the hydraulic control pipes (E) and (F) into the tractor attachments.
“Warning!
Before proceeding to the positioning of the machine it is necessary to do an attentive preventive visual verication in order to individualise
possible damages undergone during the phases of transport.”
In the case in which one or more components were turning out to be victims it is indispensable not to proceed further with
the installation and to indicate to the rm builder the found anomaly, when there were agreeing with the same one the
actions to be made. During the cleaning operation the attached staff must be provided with the individual protection devices
necessary (DPI).
“Warning!
To verify that the zone chosen for the positioning has a surface of support adjusted to the weight of the machine.
The hydraulic, electric connections must be carried out at expert and suitably trained staff provided with the necessary devices of individual
protection (DPI). To avoid folding the flexible pipes. To prevent the flexible pipes and the electric cables from being in contact with sharp-cornered
or cutting parts. The assembling and the regulations of the equipment must be carried out by machine it stops, with the de-activated fountains of
energy. Before making any manual, necessary movement for the regulations and adjusted of the machine and of the equipment, to be veried that
work zone is it moves at persons’ and varied tools and that anomalies, waves do not exist to avoid dangers for the persons and damages of the

Connecting the shaft
Before using the cardan shaft, read the user manual and the maintenance manual attached to it.
If the cardan shaft supplied with the machine is not used, check that the machine and tractor headphones overlap the car-
dan shaft guard with at least the required size (5 cm).
Clean and lubricate the power socket.
If necessary, grease the cardan shaft according to the instructions given by the cardan manufacturer (see Manual for use
and maintenance of the cardan shaft).
Engage on one side of the machine multiplier by respecting the mounting direction prescribed by the manufacturer and indi-
cated on the outer cover of the guard, on the other on the power take-off of the tractor.
Hook the anti-rotation chains.
Make sure that the anti-shock wrench (button) is properly engaged and locked in its housing.
If the pivot shaft does not have a pushbutton lock but has a bolt, always make sure the bolt is snapped tightly.
“Beware!
Make sure the drive speed is selected before the p.d.p. drive, that the selected speed number coincides with the machine’s allowed RPM (1000
rpm). Stop the p.d.p. When lifting the tool or showing too large angles in the maneuver. The cardan shaft must always be connected to last p.d.p. Of
the tractor and disconnected rst at the end of the work. “
Only use CE marking shafts for correct and safe operation of the machine.
Use only cardan shafts with unprotected protections. The length of the shaft must be appropriate to the type of tractor you
are using.
If a cardan shaft other than that provided with the machine is used, make sure that it is of adequate length. This means that
at the maximum extension time, the two shaft tubes must be at least 15 cm in length, and in the minimum extension time, the
two shaft hoses must provide at least 5 cm free light.
If these measures are not guaranteed, do the following:
• Remove the cardan shaft from the plastic caps;
• Cut them in order to obtain an adequate length;
• Cut the inner tubes of the same length;
• Remove any discoloration with a le;
• Grease the metal parts;
• Replace the plastic caps.
• When the cardan shaft is disconnected from the power take-off of the tractor it must always
• be supported on the appropriate support.
Omarv is not responsible for damage caused by improper installation and use of the transmission
gimbal.
Hydraulic connections for opening the machine
The BOLOGNA crushing machine is a folding machine, which allows it to decrease its dimensions while moving. To allow this
movement, the machine is equipped with a simple effect hydraulic jack.
The drive of the jacks is entrusted to the tractor hydraulic outlets. Before connecting the quick couplings to the tractor distri-
butor make sure that the tractor and machine side circuits are not under pressure. Make sure the quick plugs are locked in
their respective seats.
“Beware!
Check for any use of the machine that there are no cuts or abrasions on the hydraulic hoses to avoid the risk of injury due to the projection of pres-
sure jets and if they are to be replaced by others supplied by the manufacturer. “
Locate a leak, take all precautions to avoid accidents.
Pressurized liquids, especially oil in a hydraulic circuit, can cause serious injuries and cause infections: in case of accidents
consult a physician. As soon as the trimming is completed, the hydraulic hoses disengaged from the tractor must be placed
in the appropriate seats in the rest position. Before operating on the hydraulic system, stop the tractor engine and remove
the pressure from the circuit. To maintain the hydraulic system, use personal protective equipment
(Gloves, safety shoes, etc ...).
Do not dispose of exhausted oils and residual fat in the environment but dispose of them at disposal centers.
“Warning!
Engage the hydraulic pump only when the machine is stopped.”

Checks to be performed before commissioning
“Beware!
Before you start using the machine, and before you do anything, you need to know all the devices, controls, and functions, read this manual
carefully. Before using the machine make sure that all safety devices are properly placed in place and in good condition; If any breakages or damage
to the protections occur, replace them immediately. In particular, check that the front bulkheads are present and intact, free to oscillate around the
pin on which they are hinged. Only start the machine when the machine is in the working position on the ground.
Before using the machine make sure there are no people or animals within the range of 50 meters.
The shredder must be used with the closed back carter to minimize the danger of projection of objects (stones, wires, or tool pieces that may
break).”
“Warning!
It is forbidden to use the machine to personnel who are not authorized and not trained.
Operators carrying out permitted activities on the machine must receive appropriate instructions regarding the use of personal protective equip-
ment such as shoes, gloves, etc. Which allow them to cancel all the risks arising from the execution of the various activities.”
Keep the machine clean from foreign materials (debris, tools, various objects) that could damage it or cause damage to the
operator.
Make sure that the cardan is mounted correctly on both the tractor power jack and the machine shaft.
Verify that the cardan shaft is superimposed for at least 1/3 third of the advance in the extended position.
Ensure that the hydraulic hoses are correctly engaged with respect to the color recognition code and remember that their
inversion causes movements opposed to those commanded.
Make sure the protections are in perfect order, that they can move freely and that the fastening chains are not under stress
when the machine is fully raised or lowered.
Verify that in the continuous working position, the cardan shaft does not over an angle of 20 ° in relation to the alignment of
the tractor power socket.
Make sure the cardan does not touch the tractor power outlet protection, transmission group shaft guard, or other machine
parts.
Any operation concerning the cardan or power outlet must be carried out with the engine of the stopped tractor, the ignition
key switched off and the power take-off shaft in stop position.
The operator must wear safety shoes, safety gloves, safety helmets and safety goggles during the period of use, maintenan-
ce, repair, roadside or storage of the machine to protect against falling objects or projections due to operation of the car. The
clothing of the operator must be as close to the body as possible.
Never use large clothing or aming clothing.
If iron or similar materials twist the rotor, try to release it manually (wear safety gloves) or with the help of shears. Do not
attempt to reverse the rotation direction of the rotor.
Do not allow anyone to get on the tractor or on the car. Do not do any operation if a person is near or on the machine. Do not
allow anyone to approach, especially children.
Check the machine periodically, inspect the bolts in general, damaged or broken parts, pinched or broken cables, loose ttin-
gs, or too much play. Make sure all pins are properly locked. Always keep the machines perfectly clean and free from objects.
Immediately clean stains of oil or other ammable materials to avoid re hazard.
Serious wounds may result from these maintenance negligence.
Do not continue to use the machine if a knife is lost or deteriorated, causing vibration. Refer to the instruction manual for the
prescribed chapter and replace it. Always replace a knife at the same time as the opposite one on the rotor. Always select the
rotor stop position before removing the shaft from a power outlet on a fully independent power take-off tractor.
Operation
“Beware!
Before starting any job, it is necessary to heat the tractor engine and hydraulic oil for a few minutes to ensure a quick response of the hydraulic
components. Before starting to use the machine you need to know all the devices, controls and functions, read this manual carefully. The operator
