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 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) 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.

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 8.5)
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 sprayers 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 CAMPO series 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 tractor-mounted sprayers to be used with:
a) horizontal booms per herbaceous cultivations (herbicides, insecticides,
fungicides, foliage nutrient, etc.)

d) treatments with hand lances with or without a hose reel
e) hand lances for washing with or without a hose reel

The UNIGREEN S.p.A. sprayers are identified by the CE plate (FIG. 2) bearing

4 USER’S INSTRUCTIONS

4.1 DESCRIPTION OF THE MACHINE

The sprayers are made of a structural steel frame and a polyester tank reinforced
with fibreglass or high-density polyethylene.
The frame is painted with special fired epoxy paints or, depending on the
versions, 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 fitted with pistons.
The accessories that can be used to complete the sprayer include: lifting devices,
self-levelling devices, mechanical or hydraulic herbicide booms, jets and nozzles
and this makes the UNIGREEN sprayer 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.
NOTE: Put the ladder back into the correct operating position after use,
securing it with the hook; make sure not to pinch or crush your hands during
these operations.

4.1.2HAND WASHING TANKS

The sprayers 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° 12 pag. 33-34. (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°

11).
= that the hose clips and all the unions and connections are tightened
properly.

= that any herbicide boom is mounted in the centre.
= that all of the protective covers are fitted solidly to the machine, in particular

the protective cover of the power-takeoff of the pump.
= Check the proper tyres inflation (pressure are indicated on tyres)

This symbol identifies the
clean water tank on the
machine used to wash
your hands

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 (Fig. 2); use slings and
lifting gear with a adequate load-bearing capacity.
Don’t stand the sprayer on soft ground or steep slopes.
Never lift or move the sprayers 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 booms.
Don’t pass or stand under the machine when it is being lifted.

4.3.1 TOWED SPRAYERS

PARKING
Don’t stand the sprayers 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°
using the relevant chocks (FIG. 3) in the following way:

- Machine parked with drawbar uphill (max 8.5°), place the chocks behind
the wheels.

- Machine parked with drawbar downhill (max 8.5°), place the chocks in front of
the wheels.

- Machine parked across the slope (max 8.5°), place one chock in front of the
drawbar wheel (in the direction of the slope) and the other in front of the wheel
uphill.

MOVING THE MACHINE
For lifting, please refer to the general notes above.
CAMPO sprayer models 11 and 16 are fitted with a tilting parking wheel which
allows the machine to be pushed over firm, flat ground when the tank is empty.
CAMPO sprayer models 22 and 32 are fitted with a tilting parking foot.
To make it easier to move the sprayer when it is not attached to the tractor, the
machine and the drawbar are specially equipped for stowing:

- The cardan shaft: swivelling cradle on drawbar.

- The electrical pressure regulator: hosereel support (the pushbutton panel is
normally attached to the tractor or stored in the product basket).

Hinged parking stand

Tractor coupling for Towed machines:
standard version, with elevator coupling.

Tractor coupling for homologated Towed
machines in work position (not suitable for
road use).

4.4 TRACTOR COUPLING = The tractor must be equipped with a 1”3/8 ASAE DIN 9611/A at 550 rpm

power-takeoff capable of supplying the power necessary for operating the
machine.
= It must have a towing hitch (towed mistblowers with a towing eye or fork
drawbar) and a three-point elevator (for mounted machines and a steering
drawbar for towed machines) suitable for safely bearing the weight of the

= It must be able to tow the maximum overall mass of the machine.
All of the characteristics required are indicated in the fittings tables N° 12
pages 33-34 (the total mass is also indicated on the CE plate on the machine).

WARNING: make sure there are no persons or things near the
mistblower before starting the machine and while you are using it.

4.4.1 STANDARD VERSION (ELEVATOR COUPLING)

= Check the diameter of the elevator coupling pins. If necessary position the
double diameter pins correctly; there are also appropriate adapter bushes
available.
= Check that the weight on the hook can be supported by the tractor (the
maximum weights on the drawbar are indicated in the fittings tables N° 12
pages 33-34).
= Check that the steering joint is lubricated with grease.
= Keep the towed machine level with the control of the elevator.
= Retract the parking drawbar wheel (or foot) so it doesn’t get damaged during
work.
B: to perform these operations, check the stability of the machine and observe
all the indications relevant to safety in the paragraphs 4.3 TRANSPORTATION
AND MAINTENANCE, 8 MAINTENANCE, and 8.5 REPAIRS.
= Position the pressure regulator in a place where it is easy to reach from the
driver’s seat. Don’t carry liquids under pressure inside the cabin; use the
relevant electrical or cable controls for these tractors.
= Check that the pipes of the pressure regulator (or the electrical cables on a
pushbutton control panel) don’t get in the way and are positioned at a safe
distance from the cardan shaft and the wheels of the tractor.

4.4.2 HOOK VERSION (HOMOLOGATED) = Check that the weight on the hook can be supported by the tractor (the

maximum weights on the drawbar are indicated in the fittings tables N° 12
pages 33-34).
= If the machine is coupled to the tractor by a tow hook, adjust the height of
the hook to keep the tank of the sprayer horizontal.
= When you have connected the drawbar proceed as for the towing steering
drawbar.

Tractor coupling for Towed machines:

4.4.3 PARKING FOOT

After attaching the drawbar to the tractor, you must retract the parking foot (or
wheel) to prevent damage during operation.
Retract the foot as follows:
= lift the machine up about 20 cm using the tractor’s elevator (if the machine
is instead attached to the trailer hook, retract the parking foot by turning the
knob)
= Take out the blocking pin and push the foot up towards the back of the
machine.
= Hold the foot horizontal and put the blocking pin back in, inserting the
handle in the slot to keep it from accidentally slipping out.

NOTE: to put the foot back into parking position when you unhook the machine
from the tractor after operation, make sure that you follow these instructions:
= hold up the foot with one hand, while pulling out the blocking pin with the
other (guide the foot all the way down with your hand).
= put the blocking pin back in, adjust the height to keep the tank of the sprayer
horizontal.

4.4.4 WHEEL SPACING ADJUSTMENT

To adjust the wheel spacing, you must lift up the machine as described in 4.3,
or use a jack underneath the machine chassis; if you use a jack, the machine
must be hooked up to the tractor so it is properly braked.
The correct position for the jack is shown on the machine in the illustration to
the side. Check that the jack is resting steadily on a firm, solid surface.
To adjust the spacing, just loosen the screws holding the axle and pull the hub
out to the desired position, then secure it again with the screws.

WARNING: axle track should be adjusted by authorized Unigreen personnel.
The length (L) of the axle section inserted in the chassis must never be less
than the one indicated in the chart, and the overhang (S) must not be greater;
incorrect positioning of the hubs could weaken the axle and cause breakage.

4.4.5 HYDRAULIC CONNECTION TO THE DISTRIBUTORS

The machines that need a hydraulic connection to drive the herbicide booms
are equipped with 1/2", “Push-Pull”, quick-fit male couplings. You can connect
the pipes by simply pushing them in, making sure you:

- proceed 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. 4

The power that can be transmitted by the cardan shaft must be at least equal
to that required to run the sprayer. Consider that the power necessary to run a
sprayer without the fan is practically the same as that of the pump, the power
rating can be found in the pump instructions handbook. Generally 20 bar
pumps need 20 hp; 50 bar pumps need 30 hp. These power ratings can be
found in tables N° 12 pages 33-34.

NEVER USE THE CARDAN TRANSMISSION IF THE FOLLOWING
PROTECTIVE COVERS ARE MISSING:

12 unigreen

a)TRACTOR POWER-TAKEOFF PROTECTIVE COVER
b) CARDAN SHAFT PROTECTIVE COVER
c) FIXED PROTECTIVE COVER ON THE PUMP SHAFT
d) Hook any safety chains to solid anchor points
e)Check that the button or ringnut “E” (FIG. 4) is correctly engaged and

blocked both on the pump side and on the tractor side.

f) Don’t exceed an inclination of 30°-35° in any direction for any reason
g) With the machine stopped, periodically grease the spiders and the pipes,

keeping the connecting zone particularly clean.
h) 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).

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° 5) or on the 3­way deviator (FIG. N° 11 - pos A).
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 boom section tap: opens the corresponding 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.

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 - RPN - 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 (anticlock-
wise).
= 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).

Pressure regulators with a volumetric valve (RPN-DPR-ERGO-REMO)

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 ERGO and REMO)..
= 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.

4.9 DELIVERY FILTERS (ONLY EQUIPPED MODELS)

Particularly useful when using small (low volume) nozzles.
In a central position with a manometer after the filter that shows any blockages
in the cartridge. On the RVA version there is also a manometer before the car­tridge to make it easier to find the problem.
The cleaning of the cartridge in the RPV-DPR-ERGO-REMO series is fully au­tomatic (for ERGO and REMO see the previous paragraph), for the model RVA
you should open the drain with the relevant lever (Fig. N° 6) for 2-3 minutes
during the washing operations, as in the enclosed instructions.
You should clean the cartridge by hand periodically, on the basis of the product
used. To clean, stop the pump. Wear rubber gloves and the other personal pro­tective equipment when cleaning. Follow the instructions in the enclosed
manual.

FIG. 6

4.10 SPRAYING COMPUTER (OPTIONAL)

Scrupulously follow the instructions in the relevant manual when using.
We don’t recommend using the sprayer with the computer until you have had
at least one lesson from the UNIGREEN technicians.

4.11 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.

FIG. 7

a)FILLING WITH THE 3-WAY DEVIATOR (Fig. 7).

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.

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:

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.

4.12.3 PREMIXER ON HOPPER WITH TIN WASHER (OPTIONAL)

Campo 22-32 machines come equipped with the TOP-MIX S-41 premixer
(FIG. No. 10); this version of the premixer allows independent adjustment of
pressure knob, avoiding having to change the work settings of the machine
every time you have to do the premixing.
To mix the product in the tank proceed as follows:
= turn the lever of the delivery deviator to the TOP-MIX position as shown in
the pictogram on the machine.
= adjust Top-Mix pressure to approximately 10-12 bar by turning control M
(the manometer allows you to check the actual pressure)
= press lever 4 for a few seconds introducing 3-4 litres of water into the
hopper.
= open the premix, overturning the cover as shown in the photo and introdu­ce the product to mix into the hopper 1, close the cover again.
= press lever 4 to mix the product in the hopper, watching the level of the
liquid which could overflow. To prevent overflowing and to help powder
products dissolve, open tap 6) to drain into the tank.
= after emptying, close tap 6.

To wash the tin, proceed as follows:

= open the premix, overturning the cover as shown in the photo
= supply the premix using the control to regulate a pressure to under 3-4
bar
= introduce the tin into the hopper, insert washing pipe 2 into the tin, press

the tin onto the pipe until it has been completely washed.
= open tap 6 to drain into the tank at the same time.

4.12.4 TOP-MIX PREMIXER FOR CAMPO 11-16-22E (OPTIONAL)

The Top-Mix S41 premixer is also available for Campo 11-16-22E machines
as an optional feature.
Its operation is slightly different from the standard version on Campo 22-32
machines; this version of the premixer maintains an independent pressure
setting, eliminating the need to change the machine’s operating calibration
every time one has to premix.
The differences with the version described above have to do with the
calibrated nozzle (see paragraph 4.12.5) and the manometer on the premixer.
The TOP-MIX version for Campo 11-16-22E should be used as follows:
a) push the lever of the delivery deviator to the TOP-MIX position as
illustrated on the machine.
b) keep the pressure of the Top-Mix at approximately 9-12 bar by adjusting
the speed of the cardan shaft (the manometer allows you to check the actual
pressure)
c) to mix and to wash the tin, proceed as indicated in the paragraph above.

NB: At the end of all of the operations put the lever of the deviator back
into the work position.

4.12.5 TOP-MIX CALIBRATED NOZZLE FOR CAMPO 11-16-22E

The TOP-MIX S41 premixer comes with a delivery calibration nozzle mounted
on the lower block (see photo to the side); two standard nozzles are supplied,
to be mounted depending on the pump:
Comet pumps BP125-BP151-BP171-BP205 = Ø7.5 nozzle
Comet pumps BP235-BP265-BP280-BP305 = Ø10 nozzle
NOTE: when the Top-Mix is in use with the BP305 pump, pump speed must
be limited to 400 rpm.

For pumps from other manufacturers, refer to the equivalent delivery.

4.12.6 HOW TO USE THE LP83 INCORPORATOR

The TOP-MIX S41 premixer comes with an LP83 chemical incorporator,
which makes it possible to suck the product up directly from the container.
It is used as follows:

- turn pressure on in TOP-MIX premixer (see paragraph above)

- turn lever 6 down and suck the product up.

- the product is suctioned, mixed with water under pressure, and directly
incorporated in the tank of the machine.

- after incorporating the product in the tank, lift lever 6 back to a horizontal
position.
NOTE: To wash the incorporator, put it in the premixer for a few seconds,
performing the hopper washing operations described in paragraph 4.4.

Warning: Dirty equipment is very dangerous for the people and environment.
Discharging the residues of washing in the environment without taking
precautions is forbidden as this pollutes watercourses. Distribute the residues
on the treated field.

WARNING: The tank washing is controlled by tap N. 1, premix N. 2 and stirrer
N. 3.

4.13.1 CIRCUIT WASHER AND TANK WASHER

CAMPO machines can be equipped with with a circuit washer tank (FIG.11).
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 (BLUE) on
the regulator (or on pump) 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.

5 HORIZONTAL BOOMS FOR HERBACIOUS CULTIVATIONS

5.1 HYDRAULIC HERBICIDE BOOMS

These are made in of steel painted with epoxy paint or hot galvanised. The jet
booms are made of stainless steel with the jets mounted normally ever 50 cm.
All of the booms are folded onto the central body and the external arms have
safety joints to prevent breakages.
In the case of a knock the boom bends to avoid the obstacle and normally re­turns to the working position automatically. In any case the operator should try
to avoid knocking against objects as this could damage both the boom and the
obstacle in time; all the more so if the two elements get stuck.
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.

WARNING: limit movements when in proximity of power lines so as not to
exceed a height of 4 meters.

The hydraulic plant can be fed from the hydraulic pump of the tractor or be
fully independent.

- The hydraulics are controlled by a hydraulic distributor with mechanical or
electro-hydraulic controls and switches in the cabin.

- 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.
See the enclosed handbook for instructions on the use of the electrohydraulic
version (Elettroil).

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.

5.1.1 INDIPENDENT HYDRAULIC PLANT

In this case there is a tank, a filter and a hydraulic pump fitted with a flange
behind the main pump of the sprayer.

IMPORTANT:The entire plant is designed to be used at 540 RPM. Periodically
check the oil level in the tank and avoid filling it over 3/4 full as the oil might
overflow.

The tank has a filler cap with a breather, when the need arises (for repairs or to
replace a component) you can drain the oil by disconnecting the suction pipe
of the pump and collecting the oil in a recipient.

WARNING: the oil used mustn’t be dispersed in the environment and must be
collected in the relevant containers.

5.1.2 OIL FEED FROM TRACTOR

Consult the use and maintenance manual of the tractor.
Connect the delivery and discharge quick-fit coupling to the respective
connections, respecting the direction of flow.
= On booms that have a direct connection to the quick-fit couplings, each pair
of couplings feeds a cylinder.
= For booms equipped with EDR electro-deviators, follow the diagram of the
couplings supplied.
= For manual or electric distributors (Elettroil), the distributor inlet pipe is
connected to the aluminium flow separator valve next to the distributor (see
photo).
The flow separator must be adjusted correctly so it send 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 ring nuts 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.

5.2 AIR-ASSISTED BOOMS

These are booms that use air to make the treatment more effective
and decrease wind drift.
They are equipped with a fan (normally hydraulic) and an AIR­SLEEVE that transports the airflow along the entire length of the
boom.
They come with their own use and maintenance handbook, en­closed with the machine.

5.3 SELF-LEVELING DEVICES

The self-levelling device keeps the boom parallel to the ground to be treated.
It works thanks to the effect of gravity in all the models (except TDL). The
oscillation can be blocked mechanically (TDE-TDM) or hydraulically (TDI).
The Work boom has a self-levelling device with an automatic block based on
cables and springs.
The self-levelling device only works on flat ground, for hilly terrain we
recommend the version with trim corrector (TDI 2P) or hydraulic LEVELING
(TDL), which lets the operator position the boom with an inclination that is
suitable for the ground.
To use, check:
a)that the boom has been mounted in the centre, the weight of the boom must
be supported equally on the two halves. To check this, free the self-levelling
device from the mechanical (or hydraulic) block and by moving the boom make
sure it automatically adjusts its position to be parallel to the ground.
b) in the models that have an adjustable connecting rod, by adjusting the
same, it is possible to obtain small variations in trim that can be useful on
slightly uneven terrain.
c) in the hydraulic versions it is possible to fit a hydraulic cylinder (TDI 2P)
instead of the connecting rod that is adjusted by hand.
d) to complete the self-levelling device we recommend the dragging jet-saver
protections
e)keep the sliding parts well greased.

5.3.1 VARIABLE GEOMETRY

Some models of hydraulic boom are equipped with a variable geometry system
of the side arms for independent inclination, this system can be used as an
alternative to the trim correction or combined with the same.
The angle of the arms is controlled by the operator with electrohydraulic
controls.

5.4 LIFTING

The lifting devices are very useful to adjust the height of the boom on the
basis of the height of the vegetation to be treated.
The height of the boom is adjusted as follows:
= the hydraulic version has a double-effect cylinder controlled by a special
parachute stop valve.
= to lift and lower the boom use the control on the elettroil pushbutton panel
or the quick-fit couplings connected to the lifting cylinder.
= periodically lubricate the sliding guides with grease and check the guide
bolts are tightened properly, with a suitable play.

5.5 DISTRUBUTION WITH HERBICIDE BOOM

5.5.1 DESCRIPTION OF TYPE OF JETS

Various types of jets are fitted; with a single fixed (threaded or quick-fit) or
with multiple heads.
Generally they have a non-drip diaphragm and are made out of reinforced
plastic, suitable for pressures up to 15-20 bar, some models are nickel plated
brass for pressures up to 40 bar. There are versions with 2-3-4 plastic nozzle
heads and 2 brass heads.

5.5.2 DESCRIPTION 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.

a)Fan nozzles

Available in various materials: plastic-brass-stainless steel-ceramic.
They are used at pressures from 1-5 bar producing medium-large drops;
particularly suitable for pre-emergency and post-emergency weeding.

b) Conical nozzles

Generally made of ceramics, these nozzles consist of two parts; the actual
nozzle and the slinger. They are particularly resistant to wear and designed to
work from 1 to 16 bar producing a high density of small drops with a strong
turbulence. This turbulence makes them suitable for penetrating luxuriant
vegetation and so they are suitable for fungicides and insecticides. When
necessary they can also support slightly higher pressures.

c) Anti-drift nozzles

There are various models of nozzles that make it possible to reduce the
effect of drift.

d) Mirror nozzles for liquid fertilizers.

22 unigreen

5.5.3 DISTRUBUTION a)Check that all the nozzles are in a good condition and are positioned

correctly on the boom. The automatic positioning with quick heads is done for
threaded heads with the relevant adjustment wrench.
Check that the total capacity of the nozzles is at least 25% less than the
capacity of the pump.
b) Make sure the suction and delivery filters, as well as the non-drip
membranes are clean and in a good condition and that the same quantity of
liquid is supplied along the entire width of the boom.
c) Check that the height of the boom from the crops is suitable for regular
distribution. For a boom with fan nozzles fitted at 50 cm from each other; this
height is roughly 50 cm.
d) Working pressure.
The working pressure must allow for the indications in points 5.5.2 and the
following of this handbook and also allow for the speed of the tractor to obtain
the desired spraying in litres/hectare.
To assess the data, consult tables N° 1-2.
These tables are valid for spaces between the nozzles of 50cm.

To meet particular requirements UNIGREEN can supply booms with different
spaces between the nozzles and setups suitable for running at pressures
over 20 bar.
See the table below for the data conversion.

USEFUL INFORMATION
During the distribution of the product watch the pre-established speed and
pressure, following the data in the nozzles table.
The tables indicate the volume distributed per hectare for each type of
nozzle at the desired speed and pressure and are calculated as follows:

V=600xQ / IxV where: V=volume to distribute (L/HA)

Q=capacity of the nozzle (L/MIN)
I=distance between the nozzles in metres (0.5)
V = tractor speed (Km/h)

e)Considering the wear of the nozzles and a possible pressure drop in time,
to check them proceed as follows:
With the pump running at the pre-established pressure, measure the quantity
of liquid that comes out of the nozzles in L/min. Multiply this by the figure in
the table indicated below corresponding to the chosen treatment speed. The
resulting figure is the exact quantity of liquid to distribute per hectare.

5.6 MARKER

The marker indicates the zone where the treatment has been applied.
It produces a chemical foam that doesn’t damage the crops, which is
deposited on the ground and disappears after roughly an hour. The marker is
an accessory available on request. For the use and maintenance of the
system follow the instructions in the specific handbook in the package or
enclosed with machine manual.
WARNING: the foam liquid is ruined by frost, very hard water can change the
yield and function.

6 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
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 N° 3 e N° 4.

7 HOSE REEL

Available in the following sizes 20-50-100 , with mechanical, electrical and
hydraulic rotation.
To use the system, consult the enclosed handbook as there are significant
differences between each.
After work it is important to block the winding roller to stop the hose
unwinding while you are moving the sprayer.

8 MAINTENANCE

(To be done with the machine and cardan shaft stopped)
The maintenance of the sprayer is essential for maintaining a high level of safety.
Also consult the single handbooks of the main components of the sprayer.
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.

8.1 PROGRAMMED MAINTENANCE

( TAB. N° 7)
We recommend using a table of programmed maintenance to follow in time to keep
the sprayer in an efficient working condition.
For major and important maintenance jobs we recommend using the normal
UNIGREEN assistance service available from your reseller, using original
UNIGREEN spare parts.

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 (see figure)
= Check the oil level in the volumetric compensator of the pump, as indicated in

paragraph 5.1.1
= The use of chemical products that are particularly damaging for a nitrile rubber mix
(ex.. herbicides and products for rice fields) can cause the diaphragm to break before
time.
In these conditions check the state of the components more often.

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 MAINTENANCE OF THE HERBICIDE BOOM - SELF-LEVELLING DEVICE

- LIFTING SYSTEM

(to be done with the machine and cardan shaft stopped)
a)Check the state of wear of the nozzles and replace them when the delivery is over
30-35% of the theoretical level. Don’t clean with nails, bradawls or punches. Use
small brushes or compressed air.

- drain the pressure and stop the machine

- dismantle the screw or bayonet ring nuts holding the nozzles

- clean with a small brush or compressed air, don’t use nails, punches or bradawls

- reassemble the nozzles and the ring nuts, replacing the filters and seals.

b) Keep the joints greased.
c) If you are using the boom and you notice excessive pitching or the same closing

on sloping ground, you can load the spring more by screwing in the relevant nut.
d) If the external arms droop downwards after some use you can realign them using
the relevant adjustment screws:

- unscrew the locknut

- adjust the inclination by screwing in the screw

- tighten the locknut again to stop it unscrewing accidentally.

8.5 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.

Dismantling the Suction Filter

8.6 STORAGE 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.
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.

unigreen 25

8.7 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 4.4 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 4.5) following the instructions
in the present user’s handbook and in the enclosures of the pump, pressure regulator and
accessories.

8.8 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 Legislative 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.

ISTRUZIONI PER LA

RIP ARAZIONE DI UNA

CISTERNA

IN POLIETILENE

- In caso di danneggiamento si consiglia di
procedere alla riparazione procurandosi un
generatore d'aria calda (reperibile presso
qualsiasi idraulico) e chiedendo alla Uni­green il seguente Kit :
Bacchette di polietilene lineare (vari co­lori)
Blocchetti superficie piana (da cui ricava­re tasselli per la riparazione di fori di gran­di dimensioni)

- Utilizzando un taglierino, allargare in for­ma conica la zona da riparare per arrivare
al 60 ÷ 70% dello spessore.
Le parti devono essere assolutamente pu­lite.
Nel caso in cui qualche liquido abbia spor­cato la zona, se necessario, tagliare per
tutto lo spessore.

- Ammorbidire la bacchetta di polietilene
utilizzando il generatore d'aria calda.
Scaldando l'area immediatamente circo­stante la rottura con il generatore, appog­giare la bacchetta sulle parti da riparare e
ruotarla fino a fonderle insieme e
rendenderle omogenee.
Prestare attenzione ad ottenere una buo­na fusione fra la bacchetta ed il pezzo. La
linea di saldatura dovrà essere il meno vi­sibile possibile.

- Per rendere le superfici più omogenee ci
si può aiutare con un rullo metallico. Que­sto favorisce anche l'eliminazione di even­tuali bolle d'aria.
Prima di eseguire la riparazione, si consi­glia di fare una prova su un campione di
polietilene che troverete nel kit.

HOW TO REPAIR A

POLYETHYLENE TANK

- In case you have a damaged
polyethylene tank and you want to repair
it, you need the following:

-a hot air generator (obtainable from
hardware stores)

-the Unigreen basic repair kit containing
the following:

-Sticks of polyethylene in various colours

- Flat blocks of polyethylene to make plugs
and stops for larger repairs.

- Widen the area to repair in the form of a
"V", using a cutter, to 60-70% of the depth
of the material.
The opening must be absolutely clean, if
necessary cut away some of the material
all around the damaged area if it has been
dirtied by chemical products.

- Heat a stick of polyethylene to soften it
and place it in the cut, heating both the
stick and the cut to assist the weld.
For best results rotate the stick during the
operation.
Be careful to ensure good fusion and keep
the weld smooth and flat to make the
repair as least noticeable as possible.

-To assist in smooting the repair a metal
roller can be used, this will also help in
eleminating any air bubbles.
Before undertaking any repairs it is
advisable to practice on a flat piece of
material included in the kit.
