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,  
goggles- face 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 ENTERTHE 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) Refer to the present handbook for the use and maintenance of the  
frame, tank, auto-levelling systems, elevators, mechanical and hydraulic  
herbicide booms, spray booms and hose reels.  
6 unigreen  
Download from Www.Somanuals.com. All Manuals Search And Download.  
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 8.4)  
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 mistblowers 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 DESIGNEDTO 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 ONTHE ROAD  
The towed mistblowers 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.

INSTRUCTIONS  
To use the machine the personnel must be suitably trained on the basis of the regulations in  
force on safety and hygiene at work.  
THE USE OF THE MACHINE FOR PERSONS UNDER 18 YEARS OF AGE IS STRICTLY  
FORBIDDEN  
4.1 DESCRIPTION OFTHE MACHINE  
The mistblowers 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 mistblower 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 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.  
4.1.2 HAND WASHINGTANKS  
The mistblowers 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.  
This symbol identifies the clean  
water tank on the machine used  
to wash your hands

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° 18a (page 31).  
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 16).  
=
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  
This symbol  
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 (FIG.2); use slings and  
lifting gear with a adequate load-bearing capacity (FIG.3).  
identifies the  
coupling points  
of the machine  
FIG.3  
Never lift or move the mistblowers 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  
Only move and lift the machine  
with the tank empty  
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° 18a (pages 31).  
WARNING: make sure there are no persons or things near the atomiser  
before starting the machine and while you are using it.  
FIG.4  
Tractor coupling  
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° 18a (pages 31).  
For verification use the formula shown here.  
M x s < 0,2 T x i + Z x (d + i)  
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.  
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  
d) Check for the presence of the safety pins that stop the arms of the  
tractor jumping off the connecting pins.  
M = sprayer mass  
4.4.5 HYDRAULIC CONNECTIONTOTHE 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.  
FIG. 6  
FIG. 7  
The power that can be transmitted by the  
cardan shaft must be at least equal to  
that required to run the mistblower.  
These power ratings are indicated in  
tables N° 18a (page 31).  
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).  
f) For towed mistblowers with a steering drawbar, be very careful not to lift the  
arms of the elevator too high to prevent the cardan shaft touching parts of the  
drawbar.  
l) For towed mistblowers, avoid very tight steering circles with the cardan shaft  
turning (max 30°) as this could damage both the cardan shaft and the feet of the  
pump (FIG. 7).  
NEVER USE THE CARDAN TRANSMISSION IF THE FOLLOWING  
PROTECTIVE COVERS ARE MISSING:

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  
FIG. 8  
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) or on the 3-way  
deviator (FIG. N° 10, page 14).  
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.  
Don’t use the sprayer  
without having consulted  
the enclosed handbook.  
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 OFTHE 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

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.

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”).

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.  
4.8.3 DELIVERY 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).  
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 THETANK  
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.  
FIG. 10  
a) FILLING WITH THE 3-WAY DEVIATOR (Fig. 10- Fig. 11).  
It is possible to fill the tank using the pump and the floating filter kit G (cod.1002/  
0080F) with 6 metres of rubber hose (the floating filter lets you always and only  
suck up clean water).  
=
=
=
connect hose T to deviator D using the union hose adaptor supplied.  
turn the lever of deviator D to the filling position.  
place the other end of the hose, on which you fitted filter G, in the watering  
point.  
=
start the power-takeoff leaving pressure regulator C in the draining position  
(you don’t have to put the pump under pressure).  
=
=
the filling speed in litres/minute is equal to the delivery of pump P.  
visually check the level of the liquid in the tank and after filling stop the  
pump and put the lever of deviator D back in the working position.  
= disconnect pipe T from deviator D.  
FIG. 11  
b) FILLING WITH THE SUCTION FILTER (Fig. 3- 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.  
c) 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:  
FIG. 12  
=
=
=
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 auxiliary taps, see point 4.9).  
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.

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).  
The machines in the Airdrop-MFC range can be equipped with 2 hydro-  
pneumatic agitators, supplied by the relevant taps in the auxiliaries taps block

4.13 WASHINGTHE 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.  
WARNING: the indications to follow for using chemical products are indicated  
in paragraph 2.2.1.

4.13.1CIRCUIT WASHER ANDTANK WASHER  
Some machine models are fitted with a circuit washer tank (FIG.17).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.

BLOWER GROUP  
All the mistblowers 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.  
5.1 MULTIPLIER - FAN UNIT  
The Airdrop range is fitted with two versions of a Ø500 centrifugal fan: STD  
(max absorption 30 HP) and XP (max 50 HP).  
The transmission of the drive from the pump to the fan is done through a  
multiplier with one or two gears, plus neutral.  
Normally the rotation speed of the fan is 3240 RPM in first gear and 3620  
RPM in second in the 2-speed multiplier (multiplied ratios 1:6 - 1:6.7) 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).  
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).  
Ø500 fan with multiplier, 2-speed plus  
neutral.  
WORK TEMPERATURE  
For the maintenance of the multiplier (see point "Multiplier Lubrication"  
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.  
5.5 CLUTCH  
Fans 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.  
WARNING! As there is a high multiplication ratio, the fan must be started  
gradually. Suddenly engaging the power-takeoff clutch (at high speed) can  
damage the gears.

5.3 DISTRIBUTOR ACCESSORIES  
Various configurations of accessories or distributors are fitted to the outlet of  
the fans. At present these are:  
2 Fans, Canopy and Espalier - Double espalier Minibar - RV espalier and GDC  
- VL Espalier - FXF "Up and Over" boom for espalier.  
WARNING: for all adjustments, always observe the safety indications in the  
chapters relevant to maintenance and repair of this manual, as well as paragraph  
2.3.1 relevant to the use of chemical products.  
VENTAGLITENDONE  
5.3.1 VENTAGLI (FANS) CANOPY, AND ESPALIER DISTRIBUTORS  
These have been developed to adapt very simply to the type of vegetation to be  
treated.  
For dosing and distribution they are equipped with two DOSER-TAPS with 1-2-  
3-4 calibration (see chapter 6 SPRAYING).  
They turn on their own axis for the best distribution of the chemical product.  
The air-outlet section is differentiated to guarantee a greater range and  
distribution of the mixture to where it is required.  
In this way, the simple inversion of the distributors makes the system suitable  
for both the canopy and espalier versions; moving the left-hand distributor to  
the right-hand and vice-a-versa.(the same inversion must be performed for the  
two distributor taps 1-2-3-4).  
VENTAGLI SPALLIERA  
For particularly high espaliers an upper, double distributor is available as an  
OPTIONAL.  
The Ventagli accessories are available with STD and XP fans.  
MINIBAR SPALLIERA  
5.3.2 MINIBAR FOR ESPALIER  
Tangential flow head created to bring the diffusers closer to the areas to be  
treated for specific and localised operations, the vertical construction positions  
the distributors parallel to the vegetation area, guaranteeing uniform treatment.  
The variable diffusers contribute to an improved distribution of the product in  
relation to the requirements of the vegetation.  
The Minibar accessory can be used with STD fans.  
5.3.2 SUPER SPALLIERA FOR ESPALIER  
SUPER SPALLIERA  
With this accessory you can treat particular espaliers with thick vegetation. It is  
especially indicated where you need to pass beyond the rows, using a lot of air  
and power.  
The variable diffusers let you direct the product in relation to the requirements  
of the vegetation. All of the adjustments are done by hand using the knobs and  
screws.  
The SUPER ESPALIER accessory is used with XP fans.

5.3.3 RV BOOM FOR GDC  
RV per GDC  
This boom has lateral diffusers (variable and moveable) and two top  
arms with hydraulic or manual adjustment, so the jets can be directed  
onto the vegetation to be treated.  
In the bottom part there are two adjustable, telescopic distributors for  
GDC treatment.  
The height of the structure can be adjusted by hand for different types  
of vegetation.  
The RV-GDC accessory is used with XP fans.  
5.4 HYDRAULICS  
The RV, VL, VLX, FXF and FXL model distributor accessories have  
hydraulics that can be controlled by the operator directly from the seat in the  
cab.  
Check that no one and nothing is in the area where the booms will open;  
particular attention should be paid to the presence of any electric power  
lines.  
The hydraulic plant can be fed from the hydraulic pump of the tractor.  
The hydraulics can be controlled using the lever of the tractor (RV and VL) or  
a hydraulic distributor with mechanical or electro-hydraulic command with  
switches in the cabin (VLX, FXF and FXL).  
- All of the controls on both versions are sustained action controls and each  
lever or switch has a pictogram of the relevant operation it controls.  
WARNING: with hydraulic booms, don’t stand in the range of action of the  
machine.  
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.  
5.4.1 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.

SPRAYING  
WARNING: the indications to follow when using chemical products are  
indicated in paragraph 2.2.1.  
6.1 DESCRIPTION OFTHE DIFFUSERS  
The distributor accessories of the AIRDROP range are equipped with  
variable diffusers (FIG. 18) that let you direct the airflow (and as a  
consequence the treatment) on the vegetation to treat, adapting to your  
various needs.  
V
FIG. 18  
R
According to the configuration of the accessory the diffusers have outlet  
mouths with different shapes and sections, furthermore they are equipped  
with a tap for turning the liquid on/off (R) so you can independently close one  
or more diffusers in the case of scarce vegetation.  
In the VENTAGLI version the diffuser is the fan itself.  
6.1.1 NON-DRIP VALVE  
There is a non-drip valve (V) on the distributors (FIG. 18) that limits and/stops  
the mix dripping when the supply tap is closed. In any case we recommend  
closing the delivery of the mix a few seconds before disconnecting the power  
takeoff.  
In versions with fans the valve is mounted immediately upstream of the dosing  
taps (see paragraph 6.4.1)  
FIG. 19  
6.2 DESCRIPTION OFTHE MFC® NOZZLES  
The Unigreen low-volume pneumatic atomization system uses MFC®  
nozzles (FIG. 19) consisting of a steel wire supported by Nylon deflector  
vanes that also act as collectors for the liquid. The high-speed action of the  
air atomises the film of liquid on the wire; in this there is a high air/water  
surface area in contact and not just a single atomisation point, which means  
a big advantage in terms of uniformity and homogeneity of the jet.  
6.3 MIXTURE CONCENTRATION  
As you may know, the pneumatic equipment are  
used for more or less concentrated treatments.  
To prepare the mixture, it is necessary to follow  
the instructions on the chemical product label. As  
a general rule, the product quantity to be sprayed  
on the hectare is the same as normal-volume  
treatments (a 20%-reduction is also possible);  
the water volume is reduced a lot even up to 9  
times = 10 concentrations.  
We will try to clear this concept as regards  
concentration with an example for the correct  
use both of equipment and products.  
Imagine that in order to protect a normal-volume  
culture hectare you use 15 ml. of mixture. If the  
product dose recommended by the expert  
amounts to 100 g/hl. (normal-volume dose  
indicated on the label which is always to be  
followed), for 15 hl.You will use 1,5 kg. of prod-  
ucts. If you decide to reduce the water quantity  
per hectare at 500-300-150 litres (that is to say  
concentrating 3-5-10 times), in these new water  
volumes we must always use 1,5 kg. of product and 1,2 kg. if necessary (for  
reductions up to 20%). As a consequence, the mixture concentration can  
vary according to the water quantity that you wish to use.  
From this example, you can notice a reduction of 4 fillings and 12 ml. of  
water.

MISTBLOWER CALIBRATION  
The tables on pages 25 to 28 make it possible to determine the delivery in  
litres/hectares of the various equipment having the following initial data:  
- position of the batching tap levers (Ventagli - Fans)  
- calibrated plate CP (all others diffusors)  
- used pressure;  
- working speed (in km/h);  
- working length (in meters).  
20 unigreen  
Download from Www.Somanuals.com. All Manuals Search And Download.  
For instance, having a mistblower with fans and knowing:  
- the working length L = 4,0 meters;  
- the forward speed of 5,0 km/h;  
- the tap lever in position 2;  
- the pressure adjusted at 2,0 bars  
you will have a flow rate value of 7,0 l/min. and consequently of 210 l/ha.  
N.B. to calculate the different ranges it is  
sufficient to multiply the value lt/hectare by the  
corresponding width indicated in the table and  
divide it by the new width.  
Similarly, by knowing the l/ha value to be sprayed, as well as the working  
speed and distance, we can obtain the lever position and the pressure which  
is necessary for treatment.  
As the speed values indicated in the tables will hardly correspond to the real  
ones, at first it will be necessary to calibrate the speed by operating in the  
following way. With the equipment in average working conditions (half-filled  
tank), with power take-off at 500 r.p.m. and with the fan/s in operation (without  
spraying), drive a measured base of 100 meters, possibly on the field on  
which you have to work and measure the time (t) in seconds that you need to  
drive it.  
Example-  
In the table: 907lt/ha with row distance 3m.  
907x3 = 971 Lt/ha with row distance 2,8m  
2,8  
Then calculate speed according to the formula:  
V = S x 3,6 (1)  
t
whereas S is the distance in meters (in our case, 100 meters) and t is the  
time necessary to drive it.  
Example:  
if t = 66 seconds, you will have  
V = 100 x 3,6 = 5,4 km/h  
66  
It is recommended to repeat the calibration with 2-3 different gears in order to  
have more data relating to speed.  
As - beyond forward speed - also working width may not correspond to the  
ones indicated on the table, by using the flow rate in l/min. of the spraying  
head (see last line of table No. 3), you may obtain the volume in l/ha  
according to the following formula (2):  
VOLUME in l/Ha. =  
600 x l/min.  
working width (m) x working speed (km/h)  
(2)  
Therefore, if from the initial example only working speed is different from V =  
5,4 km/h, you will have:  
volume in l/ha  
=
600 x 7 = 194 l/ha  
4 x 5,4  
If also working width is different, for instance 3,5 m:  
volume in l/ha =  
600 x 7  
3,5 x 5,4  
= 222 l/ha  
FIG. 20  
6.4.1 BATCHINGTAPS (SEE PICTURE 20)  
On the equipment VENTAGLI (FANS) there are two batching taps which can  
be used to quickly change the flow rate to the jets; the long part of the lever  
shows the position (f.i. picture 20 = pos. 4). Each tap can carry out four  
different positions. In the range of each single mode, for four different  
pressures set on the regulator, we obtain four different values of the litre  
capacity per minute, for a total of 16 values as you can observe from table  
pages 25-26. An increase in pressure means an increase in capacity; a  
decrease in pressure means a decrease in capacity. For other types of heads,  
the number of positions and the pressure value can be different, as you can  
notice on the relevant tables.

6.4.2 CALIBRATED PLATES CP  
FIG. 21  
In the accessories provided with an anti-dripping valve on each sprayer, on  
the valve output there is a calibration plate which guarantees an  
homogeneous distribution among the various sprayers.  
According to the spraying table to be carried out, it is necessary to install the  
plate indicated in the table.  
ANTIDRIPPING VALVE  
MARKED SIDE  
NOTE:The plate must be mounted with the side bearing the initials towards  
the liquid output (picture 21).  
The values indicated on the tables are approximate; according to the mixture  
concentration, spraying values can be slightly different.These differences can  
be easily corrected by acting on the working pressure. Increasing pressure  
means increasing spraying and vice versa.

HAND 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  
FIG. 22  
=
A
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  
ances; 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 29).

MAINTENANCE  
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 mistblower is essential for maintaining a high level of  
safety. Also consult the single handbooks of the main components of the  
mistblower.  
WARNING: the indications to follow for using chemical products are indicated in  
paragraph 2.2.1.  
8.1 PROGRAMMED MAINTENANCE  
(TAB. N° 7, page 30)  
We recommend using a table of programmed maintenance to follow in time to  
keep the mistblower 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.  
8.2 ROUTINE 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 mistblower with  
stainless steel pressure gauges.  
8.2.1 CLEANINGTHE 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  
22 unigreen

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: waste oil must not be dispersed in the environment, to dispo-  
se of waste oil see paragraph 8.7.1.  
FIG. 23  
8.3 EXTRAORDINARY 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.  
8.4 REPAIRS  
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.  
8.5 STORAGE IN A WAREHOUSE ANDTRANSPORTATION  
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.  
If the temperature might drop to below zero, drain any residual liquid or add  
roughly 0.5 L of normal antifreeze for auto vehicles.  
To transport the machine follow the instructions in point 4.3 of the present  
handbook.  
8.6 PUTTING BACK INTO SERVICE AFTER WINTER LAYUP  
Before using the machine again after a long period of inactivity you should  
perform some general checks, following the instructions in point 4.2 and drain  
any antifreeze.  
Never start the shaft of the pump if you think there may by ice inside.To  
check this, make sure you can turn the shaft by hand without connecting  
it to the tractor.  
After you have connected the machine to the tractor (see point 4.4) following  
the instructions in the present user’s handbook and in the enclosures of the  
pump, pressure regulator and accessories.

8.7 DEMOLITION AND DISPOSAL  
When the sprayer will be put out of service you should wash it with  
great care to remove any residues of chemical product, follow the  
instructions in point 4.13 of the present handbook.  
ATTENTION: It is necessary to adopt appropriate Individual Protection  
Devices in manipulating waste.  
The disposal of waste deriving from the demolition of the machine  
must be carried out respecting the environment, avoiding soil, air and  
water pollution.  
Local legislation in force in the matter must be respected in any case.  
Remember that waste is understood as any substance or object that  
enters into the categories shown in attachment A in part IV of Legisla-  
tive Decree 152/2006, that the holder has destroyed, has decided or is  
obliged to destroy.  
Waste deriving from the demolition of the machine is classifiable as  
special waste.  
8.7.1 MATERIALS FOR DEMOLITION  
Non-dangerous special waste is that which can be recovered,  
according to the February 1998 Ministerial Decree:  
·
·
·
·
·
Iron, aluminium, stainless steel and copper materials  
Plastic materials  
Electronic cards  
Hydraulic oil  
Electrical plant  
8.7.2 INDICATIONS FOR A SUITABLETREATMENT OF WASTE  
The Correct management of special waste envisages:  
-
stocking in suitable places, avoiding mixing dangerous waste with  
the non-dangerous.  
ensuring that authorised carriers and receivers carry out its  
-
transport and disposal/recovery.  
Transport of one's waste to authorised collection centres is allowed  
exclusively if you are enrolled in the Environmental Management  
Register.  
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 Legi-  
slative 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);  
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.  
The symbol to the side, showing a barred garbage can on wheels,  
indicates the separate collection of the electrical and electronic  
apparatuses of the machine.  
The user of the present machine can contact the collection centres  
instituted by the Local Authorities or the UNIGREEN Company  
directly, or request withdrawal by the dealer, in order to carry out  
correct disposal of the waste.
