2.1 INTENDED 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.
2.2 PROHIBITED 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.
2.3 USING 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.
2.4 RECOMMENDATIONS
a) Follow the instructions in this manual for the use and maintenance of the
frame, tank, multiplier, blower groups and cannon.
unigreen 7
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.
2.5 WEATHER 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.
2.6 MACHINES 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.
2.7 DRIVING 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.
3 CHARACTERISTICS 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).
3.1 TABLES OF FITTINGS ALLOWED
Tables N° 14A-15A-16A let you identify the version of your machine indicating
the basic equipment and all the possible fittings available (optional).
You can also find the other fittings allowed or other versions to meet your
requirements in the future.
THE EQUIPMENT DEFINED IN THE TABLES OF THIS HANDBOOK (TAB:
14A-15A-16A, pages 37, 38, 39) SHOULD BE CONSIDERED BINDING FOR
THE VALIDITY OF THE DECLARATION OF CONFORMITY.
Other fittings or setups of basic components and/or optionals should be
considered unsafe and therefore are not covered by the guarantee and aren’t
UNIGREEN’s responsibility.
The same goes for fittings realised with components or accessories that aren’t
original UNIGREEN parts.
UNIGREEN accessories can easily be identified by the label with the yellow
background “ORIGINAL UNIGREEN ACCESSORY”

4 USER’S INSTRUCTIONS
4.1 DESCRIPTION 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 hot-galvanised. 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 WORK STATIONS
The use of this machine does not envisage an operator standing constantly near the
same, the operator normally sits in the cab of the tractor.
During calibration and maintenance operations the operator will be working near the
machine at ground level (for all the calibration and maintenance operations refer to the
relevant chapters).
In case of operations that request the entry to parts of the machines located at 1,5 mt.
height ,it is advised to use a ladder at rule; the ladder shall be positioned steady on a
flat ground not yielding and with the machine at a standstill and braked.
In some special models with controls above 1.5 metres there is a platform to make
these operations easier.
This platform must only be used with the machine stopped.
unigreen 9
4.1.2 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.
4.2 PRELIMINARY 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.
4.3 TRANSPORTING 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.
4.3.1 TOWED ATOMISERS
PARKING
Don’t stand the atomiser on unstable ground or steep slopes, the machine is
designed to be parked safely on compact ground with a slope of up to 8.5°
MOVING
To lift the machine, follow the instructions above.

4.4 TRACTOR 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.
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.
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
Warning: the hydraulic cylinders used are the “Double Effect” type.
Consult the use and maintenance manual of the tractor.

4.5 CARDAN 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
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).
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
4.6 PUMP
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.
4.7 SUCTION 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!!

4.8 PRESSURE 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).
Don’t use the sprayer
without having consulted
the enclosed handbook.
