2.1INTENDED USE
The sprayer in this series is built for agricultural use. The materials used are
resistant to normal chemical products used in agricultural spraying (or
herbicides) at the time of construction.
Any other use is not allowed and the manufacturer is not responsible for any
damage caused by aggressive, dense or sticky chemicals.
THE USE OF THE MACHINE BY PERSONS UNDER 18 YEARS OF AGE IS
STRICTLY FORBIDDEN
The use of liquid fertilizers in suspension is not allowed, while the use of the
same in a solution is possible if requested when the machine is ordered from
Unigreen and in any case changing some of the parts described in the
handbooks of the regulator, such as the manometer (stainless steel), the
nozzles (large diameter ceramic) and eliminating the fine mesh filters to prevent
blockages.
2.2PROHIBITED USE
Using the machine with the following products is strictly forbidden:
=Paints of any kind and type
=Solvents or thinners for paints of any kind and type
=Combustibles or lubricants of any kind and type
=LPG or gas of any kind and type
=Flammable liquids of any kind and type
=Liquid foodstuffs, whether for animals or humans
=Liquids containing granules or consistent solids
=Mixtures of various incompatible chemical products
=Liquid fertilizer or manure in suspension with lumps and/or that is
particularly dense
=Liquids with a temperature of over 40°C
=Any products that aren’t suitable for the specific use of the machine.
2.3USING CHEMICAL PRODUCTS
All pesticides or herbicides can be dangerous to humans and the environment if
used erroneously or inadvertently.
Therefore we recommend that only suitably trained persons should use these
products (license) and in any case only after having carefully read the
instructions on the container.
2.3.1 REGULATIONS FOR THE USE OF CHEMICAL PRODUCTS
Some recommendations for avoiding damage and accidents:
=Keep the machine in a suitable, protected place with no access for children
or strangers
=Handle the products with care, wearing rubber acid-proof gloves, gogglesface masks or filtering helmets, overalls made of water-repellent fabrics or
TIVEK and boots made of rubber or similar materials.
=If chemical products or mixtures of product come into contact with the
eyes or are swallowed consult a doctor immediately, taking the label of the
product with you.
=Wash all clothes that come into contact with the chemical, whether diluted
or undiluted, thoroughly before using them again.
=Don’t smoke, drink or eat when preparing or spraying the mix or near or in
the fields treated.
=DON’T ENTER THE TANK: the residues of a chemical product can cause
poisoning and suffocation.
=When spraying, respect safe distances from residential areas, water
courses, roads, sports centres and public parks or paths.
=Thoroughly wash the containers of plant protection products using the
relevant accessories, rinsing several times with clean water. The liquids used for
washing can be used for treatment.
=Collect the washed containers and send them to the relevant collection
centres. Never dispose of them in the environment and don’t use them again for
any other purpose. It is good practice to knock a hole in the bottom of the tins
so they can’t be used again.
=When you have finished spraying, wash the sprayer thoroughly, diluting the
residues with a quantity of water at least 10 times that of the residues, spraying
the resulting mix over the treated field.

2.4RECOMMENDATIONS
a)Follow the instructions in this manual for the use and maintenance of the
frame, tank, multiplier, blower groups and cannon.
Refer to the enclosed handbooks for the use and maintenance of the pump
and pressure regulator and any accessories or motors.
b)Please contact the agent in your zone, the nearest authorised workshop
or UNIGREEN S.p.A. directly for any repairs the user feels they aren’t capable
of performing alone. (see point 10.4)
c)Due to the complexity of the equipment and the variety of technologies
used (mechanical, hydraulic, oil-pressure and electrotechnical) operators must
not dismantle or modify the equipment. All of the relevant operations must be
performed by specialised personnel, authorised by UNIGREEN S.p.A.
2.4.1 TAKING PRECAUTIONS AGAINST FIRE HAZARDS
Don’t use naked flames or heat sources near the machines.
The atomisers are made with many materials that derive from petroleum:
tanks, tubes, pipes and hoses, wheels and plastic parts; furthermore the
presence of oils of various nature and residues of chemical products make
them potentially flammable.
2.5WEATHER CONDITIONS
We recommend spraying in the early hours of the morning or late in the
afternoon, avoiding the hottest time of day.
Never do any spraying if it’s raining or rain is forecast.
Don’t spray in strong wind or in any case, in winds above 3/5 m/second.
If you have to spray in windy conditions, use relatively low pressures to obtain
quite large drops that are less sensitive to drifting (being heavier the wind has
less effect). There are also special anti-drift nozzles available from UNIGREEN
S.p.A.; for information, please contact our offices.
2.6MACHINES DESIGNED TO BE USED ONLY WITH CLEAN WATER
There are versions of the machines designed only to be used with a hose reel
for washing with cold clean water.
These machines cannot be used with chemical products as they don’t have some
of the devices or accessories that are needed to use these products safely.
These machines are identified by the word “washing” on the CE plate.
2.7DRIVING ON THE ROAD
The towed atomisers are not specifically designed for road use. Nevertheless,
many models are also available in the version homologated for road traffic with
the tank empty.
You should check with your local reseller on the correct couplings to use and
use tractors that meet the regulations in force.
3CHARACTERISTICS AND SPECIFICATIONS
This handbook is valid for mounted atomisers with axial fans for phytosanitary
treatment in orchards and vineyards, in any case for arboreal cultivation in
rows of varying nature and type.
It is also valid for cannon atomisers for the phytosanitary treatment of tall
plants and forest trees such as poplars or similar.
The axial atomisers produce a mixed spray, breaking the drops with the
pressure and the speed of the air produced by the fan.
These atomisers produced by UNIGREEN SPA are identified by the CE plate
(FIG. 2) bearing one of the marks indicated in the tables of the allowed fittings
(see the following paragraph).

4USER’S INSTRUCTIONS
4.1DESCRIPTION OF THE MACHINE
The atomisers consist of a structural steel frame and a polyester tank
reinforced with fibreglass or high-density polyethylene. The frame is hotgalvanised. The tank is easy to empty and this makes it possible to use the
machine even on hillsides.
The pumps are generally diaphragm pumps but in some cases they are fitted
with pistons.
The accessories for completing the fitting, non-drip jets and ceramic nozzles
make the UNIGREEN atomiser a highly qualified and efficient piece of
equipment.
4.1.1 HAND WASHING TANKS
The atomisers are supplied with an auxiliary hand-washing tank with clean
water and a hand tap.
This tank must always be supplied with water and the inside must be clean so
you can wash any parts of the body that come into contact with the chemical
product used.
Never drink the liquid inside.
4.2PRELIMINARY CHECKS
When you receive the machine, check that it is complete and no parts are
missing.
If there are any damaged parts, inform your local reseller or UNIGREEN
directly in good time.
When the machine is delivered, make sure you ask:
a)that the machine is delivered with all of its parts fitted and that the fitting
meets the requisites in table N° 14b-15b-16b (pages 37, 38, 39).
This procedure is necessary because for reasons of space during
transportation the machine is often delivered partially dismantled.
b)that it is tested in your presence in particular checking:
=that the suction filter and the inside of the tank are clean and free of work
residues.
=that the connections are made correctly following the basic layout (FIG.
N° 16, page 15).
=that the hose clips and all the unions and connections are tightened
properly.
=that all of the protective covers are fitted solidly to the machine, in
particular the protective cover of the power-takeoff of the pump.
=that the multiplier is sufficiently supplied with lubricant oil.
=that the zone where the fan turns hasn’t been bent by knocks during
transportation.
4.3TRANSPORTING AND MOVING THE MACHINE
Every time you have to lift the machine, before starting the operation, always
make sure the lifting gear and the relevant tools and equipment (cables,
hooks, etc..) are suitable for lifting the load and check the stability of the
same.
It is forbidden to unhook and move the machine with the tank full.
The dry weight of the machine at the maximum level of fitting and with all the
accessories allowed is stamped on the nameplate; use slings and lifting gear
with a adequate load-bearing capacity (FIG.3).
Never lift or move the atomisers by hand if there is liquid in the tank. The
machine will weigh more and the movement of the liquid can change the
centre of gravity causing uncontrolled movements.
We recommend using slings as shown in the figure, the lifting points to use on
the machine are indicated with the relevant symbol.
Don’t lift the machine with the forks of a forklift truck because the machine can
tip over due to the overhanging weight of the blower group.
Don’t pass or stand under the machine when it is being lifted.
This symbol

Tractor coupling
4.4TRACTOR COUPLING
The tractor must have 1”3/8 ASAE DIN 9611/A power-takeoff that runs at 550
rpm. It must have a 3-point elevator suitable for safely supporting the weight of
the atomiser.
Check this by consulting the table of allowed fittings N° 14A-15A-16A (pages
37, 38, 39).
WARNING: make sure there are no persons or things near the atomiser
before starting the machine and while you are using it.
FIG. 4
4.4.1 THREE-POINT COUPLING
a)We recommend carefully checking that the tractor is suitable for supporting
the weight of the fully loaded sprayer safely.
The total weight of the sprayer with all of its accessories and fittings is indicated
on the nameplate in FIG. 2 and also (in the version with the maximum fittings
allowed) in tables N° 14A-15A-16A (pages 37, 38, 39).
For verification use the formula shown here.
M x s < 0,2 T x i + Z x (d + i)
i = tractor wheelbase
d = distance from the front axis and the ballast
s = overhang from the rear axle of the
operating machine
T = mass of the tractor + operator (75kg)
Z = ballast mass
M = sprayer mass
Non-observance can result in a very dangerous situation as the tractor will lose
steering sensitivity and can tip over when driving uphill or over bumps.
b)Check the diameter of the elevator coupling pins. If necessary position the
double diameter pins correctly; there are also appropriate adapter bushes
available.
c)Adjust the length of the third point tie-rod correctly so the sprayer is
perfectly vertical in normal working position.
d)Check for the presence of the safety pins that stop the arms of the tractor
jumping off the connecting pins.
4.4.2 HYDRAULIC CONNECTION TO THE DISTRIBUTORS
Machines that need a hydraulic connection to drive the movements of the
cannon are equipped with 1/2", “Push-Pull”, quick-fit male couplings. You can
connect the pipes by simply pushing them in, making sure you:
- do so only with the engine turned off;
- lower any tools connected to the elevator of the tractor;
- carefully clean the two parts that will be coupled
10 unigreen
Warning: the hydraulic cylinders used are the “Double Effect” type.
Consult the use and maintenance manual of the tractor.
FIG. 5
4.5CARDAN SHAFT
In some models this is supplied on request.
The cardan shaft must bear the CE mark.
It must always have its own instructions that must be followed scrupulously
and it should come with a cover bearing the mark, integrated in every part.
You should have previously checked the length to avoid:
=if it is too long, DANGEROUS THRUST ON THE PUMP SHAFT
=if too short, the POSSIBILITY OF DANGEROUS BREAKAGES
FIG. 6
THE MINIMUM OVERLAP OF
THE TWO TELESCOPIC
TUBES MUST NEVER BE
LESS THAN 1/3 OF THE
LENGTH OF THE TUBES.
The power that can be transmitted by the cardan shaft must be at least equal
to that required to run the atomiser.
These power ratings are indicated in tables N° 14A-15A-16A (pages 37-38-39).
a)Hook any safety chains to solid anchor points
b)Check that the button or ringnut “E” (FIG. 6) is correctly engaged and
blocked both on the pump side and on the tractor side.
c)Don’t exceed an inclination of 30° in any direction for any reason
d)With the machine stopped, periodically grease the spiders and the pipes,
keeping the connecting zone particularly clean.
e)Avoid letting the end of the cardan shaft come into contact with the
ground with the machine stopped; use the relevant support on some versions
for this, if your machine has no support, hook the external safety chain to a
part of the frame of the machine (ex. control unit support).
FIG. 7
NEVER USE THE CARDAN TRANSMISSION IF THE FOLLOWING
PROTECTIVE COVERS ARE MISSING:
-TRACTOR POWER-TAKEOFF PROTECTIVE COVER
-CARDAN SHAFT PROTECTIVE COVER
-FIXED PROTECTIVE COVER ON THE PUMP SHAFT
4.6PUMP
When using the pump scrupulously observe the instructions in the enclosed
handbook supplied by the manufacturer.
The pump can be identified by the ratings plate on the same; the main data on
the pressure and delivery are easy to find on this plate.
Normally the pumps mustn’t exceed 550 RPM; a higher speed won’t improve
performance but there is a risk of compromising the life and safety of the
pump.
There is a safety valve on the pump, calibrated to prevent overpressure. Don’t
tamper with this valve for any reason and don’t block or obstruct the pipes
connected to it in any way.
4.7SUCTION FILTER
The sprayer is fitted with a suction filter with filter cartridges that have roughly
a 50-gauge mesh, which is equivalent to a hole of 0.4 at 0.35 mm.
An efficient filter lets the sprayer work properly.
You should periodically check that the filter cartridge is clean, this check
should be done more often if there are impurities in the liquid.
To inspect the filter cartridge wear rubber acid-proof gloves as the liquid in the
filter can come into contact with your hands when you open the filter.
Don’t perform this operation with the pump running as the depression
produced blocks the cover preventing the removal.
Before removing the cover of the filter, make sure that the same is isolated
from the tubing by unscrewing the relevant rear valve (FIG. N°8).
After washing the cartridge, reassemble the cover making sure you connect
the same to the circuit again, using the valves described above in the
opposite order.
WARNING!: Don’t disperse the washing residues in the environment!!
Don’t use the sprayer
without having consulted
the enclosed handbook.

4.8PRESSURE REGULATOR
To use the pressure regulator, follow the instructions in the enclosed handbook
scrupulously. The pressure regulator controls all of the most important spraying
functions, the thorough knowledge of its functions makes work easier and more
precise.
The working pressure and the maximum pressure of the sprayer are determined
by the pressure regulator which also protects the circuit from overpressure in
any work conditions. (In serious but very rare cases, if the connecting pipes get
blocked the pressure relief valve lets the pressure off)
In some setups there may be a pump that can reach a pressure of 50 bar controlled by a regulator designed for 20 bar. In this case the maximum pressure
that can be reached is 20 bar.
The regulators can be manual, mounted on the sprayer or at a distance to make
the controls easier to use; or electrical with a control panel in the cabin.
There are also regulator versions with mechanical remote controls with a cable.
If the tractor has a waterproof cabin the use of electrical controls is obligatory.
4.8.1 COMPONENTS OF THE PRESSURE REGULATOR
Below you will find the indications for the main models fitted on Unigreen
products.
A main ON-OFF command: “open” lets the fluid flow into the circuit in use;
“closed” empties the tank.
B maximum pressure valve: adjusted by hand with the relevant knob (drains
the excess liquid when the set pressure is reached).
C jets section tap: opens the corresponding jet boom or drains to the
compensation regulator (G).
D auxiliary tap: can be used for various accessories (it is always manual).
E volumetric pressure valve (proportional):
(when present) it regulates the spraying pressure. The valve automatically
compensates variations in speed (within the scope of the same gear ratio),
keeping the quantity of liquid supplied per surface unit (litres/hectare)
unchanged.
F self-cleaning filter: filters the delivery liquid.
G compensation regulators: suitably regulated, these make it possible to
keep the pressure constant when one or more sections of jets is closed, they
don’t influence treatments with the boom fully open.
H manometer: indicates the working pressure.
Connections:
R1 supply union
R2 drain union
R3 volumetric drain union
R4 jets section delivery union
R5 auxiliary delivery union
Control box for GCP ELETTRICO electrical regulators
I1 main control valve switch
I2 volumetric pressure valve switch (proportional)
I3 jets section valves switches
4.8.2 GENERAL INSTRUCTIONS
When using the pressure regulator, scrupulously observe the instructions in the
enclosed handbook, below you will find generic indications for the major models
fitted by Unigreen.
All the regulation and adjustment tests must be carried out with clean
water.
Pressure regulators without a volumetric valve (GCP3-way - GRH-RVA)
Adjusting the maximum pressure valve
=put main control A in the drain position (“OFF”).
=loosen the hand wheel of maximum pressure valve B completely
(anticlockwise).
=start the pump by activating the power-takeoff of the tractor at 540rpm
=open main control A (position “ON”), the manometer will be activated
=open all of the section valves C (position “ON”)
=adjust maximum pressure valve B to the working value (in any case less
than the safe maximum pressure the system can reach).
12 unigreen
Pressure regulators with a volumetric valve (GCP ELETTRICO)
Adjusting the maximum pressure valve
=put main control A in the drain position (“OFF”).
=loosen the hand wheel of maximum pressure valve B completely
(anticlockwise).
=open volumetric valve E completely.
=start the pump by activating the power-takeoff of the tractor at 540rpm
=open main control A (position “ON”), the manometer will be activated
=open the drain tap on filter F slightly (only GCP ELETTRICO).
=close volumetric valve E completely. If the pressure rises over the
maximum limit of the system, make sure maximum pressure valve B is open
(see previous indications)
=open all of the section valves C (position “ON”)
=adjust maximum pressure valve B to a value over that of the working
pressure (generally 10-14 bar) and in any case lower than the safe maximum
pressure that the system can reach.
Adjusting the volumetric pressure.
=with the volumetric pressure valve E adjust the pressure to the value the
treatment will be done at (the pressure is indicated on the nozzles tables on
the basis of the tractor speed and litres/hectare to spray)
Warning! The working pressure must be adjusted with the volumetric
valve and not with the maximum pressure valve. In the case the
working pressure is too near to the calibrated pressure of the
maximum pressure valve, the proportional valve may not be able to
compensate the speed variations correctly.
Adjusting the compensated returns
=close only one tap of section C (position “OFF”).
=adjust the corresponding compensator G until you return to the pressure
set previously (displayed on the manometer).
=open and close the tap of section C and check that the pressure remains
constant.
=repeat the above operations for all the section taps.
If the types of nozzles aren’t changed the regulations carried out will guarantee
a constant spraying of the liquid also per treatments that are done at different
working pressures.
NB: if the type of nozzle is changed then the calibrating will have to be done
again.
4.9DELIVERY FILTERS (ONLY EQUIPPED MODELS)
This is particularly useful when using small nozzles (low volume), they are
normally mounted on the jet booms and have a filter cartridge with a 40-gauge
mesh (the equivalent of a 0.4 mm hole).
In the RV version, the standard cartridge has a 86-gauge mesh (the equivalent
of a 0.25mm hole) and another manometer is mounted after the cartridge to
make fault-finding easier.
At the end of each treatment cycle you should clean the cartridge: turn the
jets to the closed position, put the command under pressure and open the tap
under the filter to drain the tank for a few minutes.
You should clean the cartridge by hand periodically, on the basis of the
product used. Stop the pump to clean. Wear rubber gloves and the other
personal protective equipment when cleaning.

4.10 FILLING THE TANK
The machines for defensive crop treatments, in consideration of the safety of
persons, animals and the protection of the environment, must only be filled
indirectly from open water courses and only by free-falling water from the
waterworks.
The pipe used for filling must never come into contact with the liquid inside the
tank and therefore the water must always fall over the upper edge of the filling
inlet and through the filter installed on it.
The tank is fitted with a transparent graduated band that shows the exact
quantity of liquid inside. This reading is precise if the tank is on flat ground; the
actual total capacity coincides with the highest number. All the filling systems
fitted by Unigreen on their production machines or on request are antipollution
and stop the liquid overflowing out of the tank.
a)FILLING WITH THE SUCTION FILTER (Fig. 10 - Fig. 11).
If the 3-way deviator isn’t fitted you can fill the tank using the coupling on the
cover of the suction filter. Unscrew the rear wing nut of the filter and using a
G1"1/2 threaded union, connect pipe T with the floating filter to the coupling.
Also in this case the filling speed in litres/minute is equal to the delivery of the
pump.
b)FILLING WITH THE ANTIPOLLUTION EJECTOR (Fig. 12)
If you are filling with an antipollution hydroejector (mounted as standard on
some models) then you should proceed as follows:
=put roughly 20-30 L of water in the tank and start the pump.
=remove the cap of ejector E and insert filling pipe T.
=place the other end of the hose, on which you fitted filter G, in the watering
point.
=open the tap that supplies the ejector (on pump P or pressure regulator C).
=increase the pressure until it reaches a value which is sufficient to suck up
the liquid.
=visually check the level of the liquid inside the tank and after filling
disconnect pipe T from the ejector, close the tap and replace the cap.
WARNING: using the taps on the
pump or in any case on the front of
the machine puts the operator near
the cardan shaft. Despite the
presence of CE standard protective
covers you should take great care.
4.11 TEST WITH CLEAN WATER
It is good practice to do a test with clean water (without chemical product in the
tank) before the first treatment to make sure the atomiser is working properly
and to get to know the controls. For instructions on how to proceed with the
treatment see the chapter SPRAYING.
4.12 MIXING
The active principle can be mixed using the relevant stirrers before and during
the treatment. Correct mixing and stirring is the basis of the correct distribution
on the crops. We recommend some useful accessories such as the premixer
for powders and liquids (see the following paragraph).
To mix the product in the tank proceed as follows:
14 unigreen
a) high-pressure machines from 30 to 60 bar (FIG. N° 13): run the stirrer (or

b)low pressure machines, max 20 bar
=with a drilled pipe on the drain, run the pump at roughly 540 RPM with the
pressure regulator on drain for at least 10-15 minutes. (FIG. N° 14)
=with the stirrer on a delivery, run the pump supplying the stirrer (or ejector)
at the maximum pressure available for at least 10-15 minutes. (FIG. N° 13)
FIG. 13
FIG. 14
Some models with very small tanks aren’t equipped with mixers, you should
use the drain of the pressure regulator: run the pump at roughly 540 RPM with
the pressure regulator in the drain position for at least 10-15 minutes. (FIG. N°
15)
4.12.1 MANUAL PREMIXING
Dilute the active principle by hand before introducing it into the tank, (you
must wear suitable protective clothing such as rubber gloves, a mask or
goggles, overalls, etc.).
4.12.2 PREMIXER ON COVER (OPTIONAL):
Open the cover and pour all of the chemical powder into the filter, close the
cover and open the supply tap until all of the powder has dissolved.
4.13 WASHING THE ATOMISER
After every treatment, thoroughly clean the equipment, washing it with water
inside and out. Dirty equipment is very dangerous for people and in particular
for children.
Discharging the residues of washing in the environment without taking
precautions is forbidden as this pollutes water courses. Distribute the residues
on the field or the crops where they won’t cause any damage.
FIG. 15
4.13.1 CIRCUIT WASHER AND TANK WASHER
Some machine models are fitted with a circuit washer tank (FIG.16). This tank
must be filled with clean water and used to rinse the entire circuit including the
suction, delivery, pump, pressure regulator, jets and nozzles. Thanks to the
practical rotary nozzle it also rinses the inside surfaces of the tank.
NB: To completely clean the tank and the pipes of any residues of the various
active principles, we recommend adding 2kg of soda to the washing liquid for
every 100 L of water.
At the end of the treatment, wash the circuit and the tank.
a)Stop the diaphragm pump disengaging the power-takeoff.
b)Check you have filled the circuit washer tank (C).
c)Make sure the main control of the pressure regulator is OFF and that all
the boom sectors are closed.
d)Turn suction deviator A to the circuit washer position (H2O).
e)Start the diaphragm pump by engaging the power-takeoff.
f)Increase the engine speed until all of the liquid in circuit washer tank C
has been sucked up.
g)Turn the diaphragm pump off and turn deviator A to the work position
(TANK).
h)Turn the main control to ON, so there is pressure in the circuit.
i)Start the diaphragm pump again and use the tank washing tap on the
regulator (or on pump P) that supplies jet B.
j)After a few minutes you can close the tank washing tap
k)Distribute the washing residues over a portion of the field where it won’t
cause damage.
l)After you have finished washing, stop the diaphragm pump.

5BLOWER GROUP
All the atomisers have a high speed fan rotor. You must take great care
and beware of the effects that this can provoke: such as the aspiration
and projection of foreign bodies which, although of a small size, can be
very dangerous especially for the eyes and face.
Belt tensioning
system
FIG. 17
Belt tensioning
system
FIG. 18
5.1AXIAL BLOWER GROUP WITH PULLEY
The atomisers that have a drive transmission between the pump and fan with
pulleys are equipped with a neutral gear; the multiplied ratio is 1:4.26, the
rotation speed of the fan is 2,300 RPM.
You should periodically check the tension of the belts; if they become too slack
you should tension them again.
To do this for the models equipped with a specific system belt tensioning system, use the screw indicated to the side ( FIG. 17).
For all the other models use an adjustable wrench on the nut indicated in the
figure to the side to move the base and tension the belts (FIG. 18)
5.2AXIAL BLOWER GROUP WITH MULTIPLIER
The transmission of the drive from the pump to the fan is done through a
multiplier with one or two neutral gears.
Normally the rotation speed of the fan is 1950 RPM in first gear and 2500 RPM
in second in the multiplier with 2 gear ratios (multiplied ratios 1:3.6 - 1:4.6) and
2,500 RPM in the multiplier with one gear ratio (1:4.6)with the power-takeoff
running at 540 RPM.
You can change from one gear to the next with the lever on the multiplier, made
accessible through the opening on the side in the rear left part of the machine or
at a distance on the right side. The lever has 2 or 3 positions depending on the
number of gears and the central position is neutral (to use only the pump
without the fan).
FIG. 19A
FIG. 19B
Speed change
lever
There are two models of blower groups with rear suction:
- Axial blower (FIG19A): used for treatments similar to traditional multiplier
blower groups, with delivery of the air in a circular crown.
- Tangential blower: for use in small and medium espalier rows of vines. There
are pulley drive versions or multiplier versions, adjustable jets can be mounted
to spray the vegetation at various heights.
WARNING: the gear change lever must only be used with the power-takeoff
disengaged and the fan stopped. If it is difficult to engage, turn the cardan shaft
slightly by hand to find the right position of the lever (make sure the tractor is
turned off).
There are two deflectors (one on the right and one on the left) in the bottom part
of the delivery outlet of the fan groups which define the direction of the airflow;
lower if the deflector is lowered and higher if the deflector is raised. For the
system to work properly it should be set up as follows: the left deflector
(looking at the atomiser from behind) raised and the right one lowered in
machines with a multiplier, vice versa in those with a pulley (as the fan turns in
the opposite direction).
For the maintenance of the multiplier (see point 8.2.3 Multiplier Lubrication).
16 unigreen
WORK TEMPERATURE
Heat is generated by the friction between the various moving components and on
the basis of the power transmitted. The temperature
of the multiplier or disengaging box depends on the capacity to dissipate heat to
the surrounding environment and therefore the surfaces involved in the heat
exchange and the environmental conditions.
The specifications refer to environmental conditions with a temperature between
-10° +50°C (14°C -122°F).
The working temperature limit of the box is 90°C (200°F) established to prevent the
ageing of the seals and guarantee a sufficient viscosity of the oil. The heat makes
the air in the box expand and therefore increases the pressure inside. The correct
use of the oil seals is guaranteed up to an internal pressure of 0.5 bar. Boxes
designed to be used for particularly heavy duty work are equipped
with a breather cap that can be fitted
on any cast iron box on request.
5.3BLOWER GROUP WITH FRONT SUCTION
These models have front suction with delivery of the air obliquely to the rear of
the machine. This characteristic guarantees greater penetration into the vegetation (see fig. 20A-20B)
There are two models of blower groups with front suction:
- Axial fan: used for treatments similar to traditional multiplier blower groups,
with delivery of the air in a circular crown (fig. 20A-B).
- Tangential fan: for use in small and medium espalier rows of vines. There
are pulley drive versions or multiplier versions, adjustable jets can be mounted
to spray the vegetation at various heights.
The vanes of these blowers have an inclination that can be adjusted by 5°, with
positions from 20° to 40° (as standard this is set at 35°); to adjust the inclination you have to order the appropriate adjustment discs. This operation must
only be performed by qualified personnel respecting the position of the single
vanes so as not to vary the dynamic balance of the fan; unbalanced blowers
can cause rapid wear of the multiplier and the fan rotor itself making the machine unsafe.
FIG. 20A
FIG. 20B
5.3.1 SINGLE-SIDE BLOWER GROUP
The sprayer can be equipped with a single-side blower group like the one
shown in figure 21. The operating principle is similar to that of the blower group
with front suction, the only difference being that the treatment is only on one
side.
5.4AXIAL ROTOR
Generally the new models of rotors are fitted with 7 vanes made of aluminium
or nylon + fibreglass and the vanes have a variable inclination from 20° to 40°
with step adjustment by 5° (in some cases there are drilled reference discs)
FIG. 22.
The angular movement of all of the vanes, if done correctly, doesn’t change
the dynamic balance of the blower group.
To change the inclination of the vanes (as standard this is set at 35°) proceed
as follows:
a)Remove the protective grill.
b)Unscrew screws A that hold the spinner (central cover), each vane has
two blocking screws B at the side, one on the right and one on the left.
Unscrew the two screws enough to turn the vane the degrees necessary
(replace the drilled discs when fitted). To make the adjustment easier, there
are reference notches on blocking element C.c)After you have positioned the vane, perform the same operation on the
next one and screw the screws of the first in enough to block it in place.
d)Repeat the operation on all the vanes and after you’ve checked that all
have the same angle, reassemble the spinner and the protective grill.
The fan is balanced dynamically; the different numbers of washers under the
screws blocking the vanes are for balancing.
You shouldn’t change the position of the washers or add or remove any. Only
tighten down the screws with moderate force as they have an aluminium
thread.

unigreen 17
FIG. 23
FIG. 24
5.5CLUTCH
Big aluminium and nylon blowers have a centrifugal type clutch that makes it
possible to engage the fan rotor gradually.
This prevents jerky starts, due to the inertia of the fan rotor, which can have a
negative effect on the transmission.
For the centrifugal clutch to work properly the speed of the power-takeoff
mustn’t be less than 450 rpm, especially if you are using the first gear of the
multiplier.
Generally clutches with shoes/plates made of sintered material with a high
coefficient of friction are fitted, on some low power models rubber clutches may
be fitted.
5.6OPTIONAL DEFLECTORS AND ACCESSORIES
The atomisers are fitted with deflectors underneath for the optimal regulation of
the airflow towards the zone to be treated. To adjust these, simply pull or push
the deflector, positioning it in the desired way (FIG.23).
Top deflectors can also be supplied on request to improve the regulation of the
airflow towards the lateral zones without dispersing the product upwards. To adjust these, simply loosen the black lever (shown in figure 24), position the deflectors and lock the lever again.
5.7CANNON BLOWER GROUP
The cannon blower group is equipped with a multiplier similar to the normal axial
blower groups and all of its operating characteristics are the same.
The main difference with respect to the axial blower groups is that the
centrifugal fan rotor is made of galvanised steel, the fan rotors in this type are
fixed and can’t be adjusted, for the clutch see the previous paragraph. This fan
rotor can usually produce a delivery which is much higher with a very high
speed airflow (Fig. 25).
FIG. 25
18 unigreen
The cannon fan is mounted on a thrust block that can be adjusted by hand by
unscrewing the relevant locking screw. This adjustment must be done with the
fan rotor stopped because the high speed of the air make the movement of the
fan dangerous.
5.7.1 MANUALLY INCLINABILE HEAD
The cannon blower group can be equipped with a pivoting head (max inclination
180°) adjustable by hand.
5.7.2 HYDRAULIC DRIVEN HEADS
On request hydraulic pivoting (inclination 90° roughly) and rotating (max rotation
270°) heads are available.
5.7.3 HYDRAULIC DRIVES
The cannon fans can be equipped with hydraulic drives: with the cylinder fitted
directly (30° inclination roughly) or a motor with a pinion and chain (180°
inclination roughly).
5.7.4 OIL FEED FROM TRACTOR
(for hydraulic systems)
Connect the delivery and discharge quick-fit coupling to the respective
connections, respecting the direction of flow.
The distributor inlet pipe is connected to the aluminium flow separator valve
next to the distributor.
The flow separator must be adjusted correctly so it sends less than 4-5 L/1° to
the distributor.
To prevent the cylinders moving at a dangerous speed, adjust the relevant
chokes near the cylinders. If the registration ringnuts aren’t visible then fixed
chokes are fitted. The chokes are fitted on the discharge line of the movement
to slow.
Any impurities in the oil could block the chokes and as a consequence block
the cylinder; remove the dirt if necessary. The maximum pressure valves of the
distributors are regulated to a pressure of around 150 bar.
To prevent the excessive heating of the oil we recommend supplying the
distributor of the sprayer only when the cylinders are being used.
We recommend having qualified personnel do any adjustments.
Pay attention to the integrity and efficiency of the hydraulic components and in
particular to the pipes to prevent the risk of bursting.
Do a full check on the pipes and components at least once a year, we
recommend replacing hydraulic pipes every 3-4 years.
6SPRAYING
6.1DESCRIPTION OF TYPE OF JETS
Various types of jets are fitted; with a single or double head.
Generally they have a non-drip diaphragm and are made out of brass, suitable
for pressures up to 40 bar, some models are nickel plated.
The jets can be equipped with different types of nozzles, changing the locking
ringnuts. The jets used normally have high volume, Ø18, ceramic plates and
low volume conical nozzles (Albuz ATR or Teejet TXB). The jets for cannons
have a jet holder with adjustable delivery and spray that has high volume,
ceramic plates, Ø15 instead of 18.
All the jets normally used have three positions (FIG. 26):
a)spray - if the nozzle is pointing outwards, away from the blower group,
parallel with the non-drip valve
b)closed - if the nozzle is at 90° with respect to the non-drip valve or, for the
single jet if it is facing inwards towards the blower group
c)nozzle second spray - when these are pointing towards the outside of the
blower group parallel with the non-drip valve.
6.2DESCRIPTION OF TYPE OF NOZZLES
The nozzles are extremely important to obtain a correct distribution on the
vegetation to be treated. Poor quality or worn nozzles have a tendency to
create unevenly treated strips.
The nozzles are produced in various sizes, to work with a precise pressure
range, to create certain types of larger or smaller drops; using nozzles for a
purpose they are not envisaged for prejudices the precision and duration of the
nozzles.
6.2.1 NORMAL VOLUME CONICAL NOZZLES (OVER 500L/HA)
Generally made of ceramics, these nozzles consist of various parts; the actual
nozzle, the stainless steel slinger and a series of seals. They are particularly
resistant to wear and are designed to work also at high-pressure (25-45 bar)
producing drops of an average size with strong turbulence. This turbulence
makes them suitable for penetrating luxuriant vegetation and so they are
suitable for fungicides and insecticides. There are various sizes and the
capacities are indicated in table N° 1, page 33.
6.2.2 LOW VOLUME CONICAL NOZZLES (150-500L/HA)
Made of two ceramic pieces with colour-coded plastic inserts, they are
available in various sizes identified by the colour (see tables 2 and 3 page
33).
They have been specifically designed to obtain a large number of small drops
with strong turbulence even at low pressures (2-3 bar). This turbulence makes
them suitable for penetrating luxuriant vegetation and so they are suitable for
fungicides and insecticides. The nozzles of the TR Lechler and TXA Teejet
series are in this category.
FIG. 26
6.2.3 ANTI-DRIFT NOZZLES
Specific anti-drift nozzles are available from Unigreen. The main characteristic
of these nozzles is that they eliminate the fog effect caused by the presence
of drops that are too small and are particularly sensitive to drifting. For further
information please contact Unigreen for the relevant instruction handbook.

NB: for calculating a different space between
rows simply multiply the litres/hectare value by
the corresponding width indicated in the table
and divide it by the new width.
EXAMPLE:
in the table: 907 Lt/ha with a space between the
rows of 3m
907x3 = 971 Lt/ha with a space between
2,8the rows of 2.8m
6.3CALIBRATING AXIAL FAN ATOMISERS
(Tables on pages 25 - 30)
The tables on pages 25-30 let you easily calculate the distribution in litres/
hectare of the atomisers with the standard fittings, proceeding as indicated
below:
a) Choose the table relevant to the blower group of the atomiser in question (the
main reference is the number of jets)
b) Find the distance between the rows of the vegetation and the diameter of the
nozzles used (ceramic plates, TR or TXA).
c) In the horizontal strip, choose the working speed and the distribution in litres/
hectare and on the vertical scale find the pressure to use.
d) Adjust the pressure to obtain the treatment required.
If the distance between the rows is different from that in the table you can easily
calculate the distribution in proportion: for example with a distance between the
rows of 8 m, divide the figure for the litres/hectare of the distance between the 4
m rows by half, with a distance between the rows of 2.5 m double the figure for
the distance between the 5 m rows.
The last line of the table indicates the overall delivery of the fan.
If the atomiser is fitted with non-standard nozzles, the spraying tables of the
single nozzles per atomiser are on page 34.
To calculate the distribution in litres/hectare, use the following formula:
Vd = 600 x Q
I x Vwhere:Vd= volume to distribute (L/ha)
Q= sum of the nozzles delivery (L/min)
I= distance between the rows (m)
V= tractor speed (Km/h)
EXAMPLE:
Distance between the rows: 5 m
Speed: 6 Km. / h
Working air pressure 30 bar
Fan Ø 800 with 14 standard, high volume nozzles (Ø 1.0)
Q total delivery of the nozzles (Tab. 1 page 34) 2.96x14= 41.44 L/min
Vd = 600 x 41.44 = 829 L/ha
5 x 6
N.B. : Depending on the season the vegetation may be more or less luxuriant;
bear this in mind before starting the treatment. If the plants don’t have much
foliage you should diminish the quantity of litres per hectare using lower
pressures or closing one or more jets of the fan.
6.4CALIBRATING CANNON ATOMISERS
( Tables on pages 31-33 )
Atomisers with a cannon blower group are mainly intended for treating forest
trees or other tall plants that it is impossible to drive into with the sprayer (for
example tobacco or similar cultivations). They are also frequently used in cultivation under mobile greenhouses.
When shooting the atomised chemical mix at distances, that can even be over
40 m, it isn’t possible to verify with the exact distribution on the area treated.
Due to the effect of the wind, the presence of turbulence and the obstacle of
the same plants being treated, we don’t recommend using cannons with
chemical products that need to be distributed with great precision.
Don’t use herbicides or similar products.
20 unigreen
6.4.1 TREATMENTS ON TALL PLANTS
a) Use the tables of pages 31-33 choosing the one relevant to the type of
cannon to use and the number of jets.
b) On the last line choose the delivery in L/minute that goes with the chosen
working pressure.
c) Then spray the litres desired on the plant defining the necessary treatment time.
When treating a poplar grove or in similar situation there are photocells for the
automatic management of the opening of the jet in the presence of the plant to
treat, available on request.
6.4.2 TREATMENTS ON HERBACEOUS CULTIVATIONS
a) Use the tables of pages 31-33 choosing the one relevant to the type of
cannon to use and the number of jets.
b) Find the range and the diameter of the nozzles used (ceramic plate or TR
nozzles).
c) In the horizontal strip, choose the working speed and the distribution in
litres/hectare and on the vertical scale find the pressure to use.
d) Adjust the pressure to obtain the treatment required.
Note: the minimum range indicated in the table can vary significantly
according to the adjustment of the single jets (screwed in more or less).
To verify the exact delivery of the fan do tests with clean water.
7HAND LANCES
When using hand lances bear in mind the following notes:
=Don’t direct the jet of liquid towards electric power lines or zones where
there is electrical current, houses or where people might pass.
= Don’t point the jet at people or animals.
The jet can cause serious injuries simply due to the mechanical force of the
liquid under pressure.
=Never block the spraying lever of the lance in an open position because if
the lance falls it will be uncontrollable.
=At the end of work after you have stopped the pump, make sure that any
residual pressure in the pipes under pressure has been drained to avoid
unexpected jets when putting the lance away.
There are various types of lances; with a lever, mitra spray gun and pistol grip.
For further information please refer to the handbook in the package.
The lever lance is controlled by opening lever A which, depending on how
much it’s pressed, produces a conical spray or direct jet. The standard nozzle
is Ø 1.5
The mitra spray gun can produce a direct jet or a conical spray and the type
of spray is selected by pushing lever B forwards or backwards. Use lever C to
open the jet. The standard nozzle is Ø 2.5
Replacement nozzles are available for all of the lances and the capacities are
indicated in the tables TAB.4 and TAB.5 ( page 34).

8MAINTENANCE
All of the maintenance operations and repairs must be carried out with the machine and cardan shaft stopped and the tank and circuit clean of any residues
of chemical products.
The maintenance of the atomiser is essential for maintaining a high level of
safety. Also consult the single handbooks of the main components of the atomiser.
8.1PROGRAMMED MAINTENANCE
(TAB. N° 7, page 36)
We recommend using a table of programmed maintenance to follow in time to
keep the atomiser in an efficient working condition.
For major and important maintenance jobs we recommend using the normal
UNIGREEN assistance service available from your reseller, (if necessary)
replacing parts using original spare parts only.
8.2ROUTINE MAINTENANCE
=After every treatment wash the inside of the tank and the entire circuit as
indicated in paragraph 4.13
=Periodically check that the suction and delivery filters are clean
=Check the oil level in the volumetric compensator of the pump
=The use of chemical products that are particularly damaging for a nitrile
rubber mix can cause the diaphragm to break before time.
In these conditions check the state of the components more often. There are
diaphragms made of special materials (viton and desmopan) that are available
on request.
=When doing treatments with copper hydroxide you should take great care
to thoroughly clean the system, washing it after each treatment because
hydroxides attack parts that aren’t painted or protected by hot galvanising.
To prevent chemical attacks we recommend spraying transparent paint on the
parts that are most exposed to the product and equipping the atomiser with
stainless steel pressure gauges.
FIG. 29
8.2.1 CLEANING THE NOZZLES
Check the state of wear of the nozzles and replace them when the delivery is
over 30-35% of the theoretical level.
If you notice even a partial blockage of a nozzle proceed as follows:
- drain the pressure and stop the machine
- dismantle the screw or bayonet ringnuts holding the nozzles
- clean with a small brush or compressed air, don’t use nails, punches or
bradawls
- reassemble the nozzles and the ringnuts, replacing the filters and seals.
8.2.2 LUBRICATION
The moving mechanical components must be lubricated to prevent wear and
overheating. This lubrication can be done with grease or oil: oil allows
significantly higher speeds, in general grease is used to lubricate bearings with
a vertical or inclined axis as it stays in the zone for longer.
8.2.3 MULTIPLIER LUBRICATION
The multiplier and disengaging boxes are normally lubricated in an “oil bath”, in
special cases NLGI n.0 grease is used. The viscosity is an essential
characteristic of a lubricant oil and this is indicated by the SAE (SOCIETY OF
AUTO-MOTIVE ENGINEERS) classification of the oils for gearboxes and
differentials. Special additives improve the capacity of the oil to maintain a
lubricant film also at high pressures and temperatures. We recommended using
SAE 90 oil for the multiplier and disengaging boxes. The quantity of oil is
established by the level cap. A greater quantity of oil doesn’t improve the
conditions of lubrication and can cause overheating in the box. Changing the oil
protects the parts from the dangers associated with wear and the presence of
metallic particles that can be present, especially in the first period of use. We
recommend replacing the oil after the first 50 working hours and then
subsequently every 500 hours.
The quantity of oil needed is indicated on the sticker near the multiplier (FIG.
23)
WARNING: the oil used mustn’t be dispersed in the environment and must
be collected the relevant containers.
22 unigreen
8.3EXTRAORDINARY MAINTENANCE
At the end of a season of intense use, or every two years of normal use, it is a
good idea to have a specialised service technician perform a general check on
the machine.
8.4REPAIRS
We recommend having the normal UNIGREEN assistance service available from our reseller
perform any repairs or contact a specialised workshop. During all of the repairs, in particular
when welding, the machine and the circuit must be clean of any residues of chemical product.
If the machine has to be lifted (for example to change a wheel) follow the instructions in point
4.3 of the present handbook.
Also make sure the machine is stopped, connected to the tractor, and use the relevant chocks
to block the wheel still on the ground.
If you use a jack (manual or hydraulic) make sure you use a jack that is suitable for the frame
so it can’t slip and put it in the right position. The jack must be placed under the main frame of
the machine near the wheel to change. Make sure the ground is compact: if necessary use
wooden beams or other sufficiently resistant material to broaden the supporting base of the
jack.
8.5STORAGE IN A WAREHOUSE AND TRANSPORTATION
The sprayer must be kept in a closed place away from excessive humidity and protected from
frost. Especially if electrical pressure regulators, electrical motors, a spraying computer or
similar components are fitted.
Before storing the machine, after you have washed it, apply a light coat of oil.

8.7.3 ELECTRICAL AND ELECTRONIC APPARATUS WASTE (EEAW)
The Italian government has adopted the European Parliament directives in the matter of the
disposal of electrical and electronic waste (EEAW) (2002/95/CE and 2003/108/CE Directives)
with Legislative Decree n° 151,July 25 2005).
The measures: in particular, the decree established measures and procedures aimed at:
a) forestalling the production of EEAW;
b) promoting the re-use, recycling and other forms of EEAW recovery, in order to reduce the
quantity to send for disposal;
c) improving, in terms of the environment, the actions of the subjects who participate in the
life-cycle of these apparatuses (producers, distributors, consumers and operators directly
involved in the treatment of EEAW);
unigreen 23
d) reducing the use of dangerous substances in electrical and electronic apparatus.
The decree imposes the limitation and elimination of several substances present in EEAW: lead,
mercury, cadmium, chrome, hexavalent chrome, polybrominated biphenyl, polybrominated diphenyl
and polybrominated diphenyl ethers.
The machine has been designed and created in conformity with this directive. Follow the indications
shown below.
