•Avoid inhaling the gases inside tanks.

rev. 03/04/2009 7
•During treatments it is advisable to use overall working clothes,
goggles, gloves, dust proof mask or helmets and boots resistant to
the chemicals.
•The sprayers are designed to broadcast chemicals in agriculture;
the constant use of chemicals makes of the machine a potentially
dangerous implement, of which everybody must be aware.
•Before using the chemicals, read and understand all the warnings
and directions given by the manufacturer of the chemical and:
LEARN OF HOW TO ACT IF ACCIDENTALLY THE CHEMICAL
WOULD BE TOUCHED BY SOMEONE OR WOULD BE SPREAD IN
THE ENVIRONMENT.

ground. Be sure that the machine is always placed in stable balance.

rev. 03/04/2009 12
SAFETY RULES FOR THE OPERATORS
BEWARE: the sprayers are machines where some parts are rotating at a
very high speed, which, even if protected, are still potentially dangerous.
1) Pay careful attention to warning, danger and marking signals that are both
contained in this handbook and affixed on the machine.
2) Any time the machine need to be serviced, the motor of the tractor must be off,
the gear engaged, the hand brake pulled and the machine must be firmly parked
on the ground.
3) Never touch parts while they are in motion. This could cause your death.
When in operation, the sprayer blows chemical products. Therefore, always
make sure that no persons or animals are within the reach of the machine.
When making this evaluation, consider also possible wind.
Minimum distance between persons and working place: 100 Mt. (300 ft).
Never work when persons are in areas at risk.
The machine must be used by one person only who must operate it from the
tractor's driver seat. Nobody else is necessary, therefore no other persons must
approach the dangerous area. Minimum distance from the machine while in
operation: 100 Mt. (300 ft.).
Should someone come too close to the machine, then immediately stop any
operation you are carrying out and warn these persons with acoustic and light

rev. 03/04/2009 13
signals until they leave the dangerous area, where they could be contaminated by
chemicals, overrun by the tractor or be injured by machine mechanisms. Risks
due to parts that are in motion and from sudden change of the wind's direction
could be unavoidable.
Never wear clothes with free ends (such as belts, scarves, heads-squares, long
skirts, etc.) that could drag you towards the machine parts while they are in
motion.
The operator should keep all shields, of which the machine is equipped, in steady
and sound conditions. After any service or repair, all the shields must be put in
the original place.
Before stopping and/or staring the engine of the tractor be sure that:
•The PTO must be disconnected
•The attached implement is firm on horizontal ground
•The hand brake is pulled
The recommended position to use the lifting system of the tractors is only from
the tractor’s seat.
Warning: It is strictly forbidden to stay between the tractor and
the machine when the engine is on.
This can cause your death.
When replacing any worn out pieces or during any other operation on the
machine (which must be carried out by skilled technicians) please proceed as
follows:
•Make sure the engine is stopped, hand brake pulled and PTO
disengaged
•In case of the need of servicing the machine from underneath, make sure
that this would rest safely on proper supports, in order to prevent any
accidental fall which would seriously injure someone.
•Every intervention must be carried out on a clean horizontal floor.
Should the machine accidentally bump into an obstacle, then proceed as follows:
•Stop immediately the machine and follow all the above-mentioned safety
instructions.
•Check the machine carefully, to be sure there are no damages. In the
case of doubts please check with the service department of an authorized
dealer.

rev. 03/04/2009 15
DELIVERY OF THE MACHINE
The machine must be checked immediately upon delivery to ensure that it is
complete with all its components; should not be the case, the manufacturer
and/or its representative must be notified at once.
The sprayer is normally supplied either wrapped with nylon or packed in a carton
and all the components are appropriately protected for shipment. In order to save
space and reducing risks of damages during transportation, some parts may be
supplied loose and need to be reassembled before using the machine. In this
case follow these instructions:
•Mount the pressure regulator on it’s support
•Mount the delivery and bypass hoses
•Check that all the hoses are tight
•Connect the hoses of the nozzles and of the handgun (if supplied)
Run the sprayer, for the first time, with fresh water, to check that everything
operates properly.
HOW OPERATING WITH A NEW MACHINE
1. Inspect for loose or missing parts and possible damages.
2. Make sure all fittings and drive components are secure.
3. Lubricate the parts that need to. See Lubrication Section for details.
4. Check tank for any foreign objects.
5. Fill tank ½ full with clean water. DO NOT add and spray chemicals until
the sprayer is started, adjusted and calibrated.

rev. 03/04/2009 16
DESCRIPTION OF THE COMPONENTS OF THE
MACHINE
PUMP
The diaphragm pump puts the liquid under pressure and is the hearth of the
sprayer – it needs therefore a particular attention.
PLEASE READ CAREFULLY THE MANUAL PROVIDED WITH THE PUMP.
TANK
The tank of the sprayer can be made either of fiberglass, polyethylene or
stainless steel. Inside the tank there is an agitation system studied in order to
keep the chemical uniformly and constantly mixed with the water, this during the
spraying operations. The agitation system can be either mechanical or jet
(sometimes both together).
It is important to have the agitation system in good working conditions at all the
times, not only for the best job with the crops, but also because some chemicals
could be dangerous if not mixed properly.
Before using any chemical, please read and apply carefully the directions printed
on its container.
DRAINAGE OF THE LIQUID OF THE TANK
It is very important to learn how and where to drain the residue liquid of the tank.
All the tanks are provided with a drain valve with a lever. Even if the valve is
designed in a way that the liquid would not touch the hands or clothes of the
operator, this has always to be opened with care.
To avoid pollution, never drain the residue chemicals on the round, but use
instead appropriate reservoirs or drain ducts.

rev. 03/04/2009 17
PROPELLER
BEFORE PERFORMING ANY MAINTENANCE ON THE PROPELLER, BE
SURE THAT THE MOTOR OF THE TRACTOR IS OFF AND THE
TRANSMISSION OF THE PROPELLER TO BE DISCONNECTED.
NEVER REMOVE THE SHIELDS OF THE PROPELLER WHEN THE TRACTOR
IS RUNNING AND THE PTO CAN BE ENGAGED.
The purpose of the propeller is to produce the volume of air necessary to atomize
the droplets of liquid sprayed by the nozzles. The result is a sort of fog that
penetrates the foliage of the plans and makes the requested treatments.
The blades can be mounted with a different angle. Wider is the angle, more is the
volume of air produced but, on other hand, there will be more absorption of power
from the tractor.
In order to change the angle of the blades (ref. 2) of the propeller (ref. 3) you
need special inserts (ref. 1) that you can receive from the manufacturer or the
dealer.
NEVER USE, ON THE SAME PROPELLER, INSERTS HAVING A DIFFERENT
ANGLE, AS THIS COULD CAUSE SEVERE DAMAGES TO THE MACHINE.
Once replaced the inserts, MOUNT ALL THE SHIELDS ON THE ORIGINAL
POSITION, THIS BEFORE RUNNING THE MOTOR.

rev. 03/04/2009 18
HAND GUN
The machine can be provided with a handgun (various models are available). The
nozzles of the handguns can have different shape, diameter of the hole,
according to the job that needs to be done.
The chart provided herewith shows different tips according to the pressure used.
The tips and the nozzles, either the ones of ceramic as well the ones of steel,
wear out and need to be replaced. Do it when you notice that the delivery has
increased or the spray pattern is not uniform.
FILTERS
The sprayer is equipped with 3 systems of filtering.
1. A basket filter is located under the main cover, the purpose of which is to
prevent that any impurity or foreign objects could get into the tank during the
operation of filling it with water.
2. A main strainer is located under the tank, connected to the inlet system. The
liquid is filtered before getting into the pump, which therefore will work with no
risk of damages. This filter is provided with a valve that prevents the return of
the liquid and that allows the maintenance of the cartridge also when the tank
is full.
3. Each nozzle is provided with one or more filters.
All the filters are of easy access and easy to clean.
NOZZLES
The machine is equipped with nozzles which can be either singe or double and
which can be adjusted to different angles of spray. By turning the nozzle of 90° it
shuts off. The double nozzles can spay dilute or concentrate, according to the
hole of the tip mounted on each side.
For the nozzles are available many types of ceramic tips with different hole,
according to the job to be done.
Tips wear out and, after a certain time, need to be replaced when the delivery
starts to be too much or the spray is no longer uniform. Inside the nozzle there is
a filter and an anti drip valve. It is recommended to clean frequently the nozzles,
filters and anti drip valves to prevent clogging.

rev. 03/04/2009 19
HITCH THE MACHINE TO THE TRACTOR
The attachment of the machine to the tractor is a dangerous operation.
It is recommended that such operation be carried out strictly complying with the
following instructions and paying careful attention.
•BEWARE: In order to attach or set the machine, any operations must be
carried out with the machine laid flat, tractor on standstill, engine off,
pulled parking brake and low gear inserted. Only the machine operator
and the technical staff authorized by the dealer can be there.
•When working on the machine make sure nobody else is coming too
close.
•Make sure the tractor power is appropriate for the machine is going to be
attached.
•Never use tractors whose power exceeds that foreseen for the machine,
as this has been tested with such power, exceeding which all machine
members could suffer serious damages that are not covered by the
guarantee.
•Make sure that the pull capacity of the tractor, as well as its weight, are
sufficient to draw the machine when this is fully loaded of liquid and ready
to work. For these important safety instructions please refer to the
owner’s manual of the tractor.
•Consider that the towed sprayer is not provided with brakes and that
particular care has to be taken when driving it down hill as well if it is
necessary to take a sharp turn. In these cases the speed of the tractor
has to be the lowest possible.
•Make sure that the tractor's draw hitch is provided with its original pin and
that this fits perfectly into the hole of the draw bar of the sprayer. Make
sure also that the pin is provided with a locking system to prevent
possible disconnection of the machine from the tractor while it is operated
or driven.
•Make sure that the weight of the machine on the hitch of the tractor
would not exceed the one shown on the label on the draw bar of the
sprayer.
