Make sure the pressure hose is connected in the direction indicated

by the arrow embossed on the filter body.

NOTE:The arrow indicates thechemical flow direction.

PUMPThe pumps mounted to Jacto cannon sprayers

have flow rate ranging from 29.062 up to 39.63 gpm.These pumps can be single-stage (one

rotor) or dual-stage (two rotors), as shown inthe section PRESENTATION OF SPRAYER -TECHNICAL SPECIFICATIONS.

The combination of a high flow rate pumpwith low power consumption allows the use of apowerful fan, making this cannon sprayer oneof the most efficient unit as regards operationalperformance.

Centrifugal pump(Single rotor)

FLOW RATE REGULATING VALVE

This valve allow to calibrate your cannon

sprayer by setting the lever within a scale from 0

to 4, giving flow rates ranging from 2.642 to 8.7186

gpm.

1636


IN-LINE FILTER

This sprayer is equipped with two in-line filters: one for the main spout and one for the auxiliary

rotary atomizer. These filters have 80 mesh and optimize the filtering of the chemical mixture flow

to the nozzles.

SPOUT

The main spout can be easily adjusted both vertically and horizontally. As the adjustment

handle is located in a convenient position to the tractor's driver, it can be adjusted even during the

application. In addition, it has an auxiliary rotary atomizer to cover the area close to the tractor,

thus improving the quality of applications.

NOZZLES

The job of the nozzles is to generate droplets and distribute them uniformly over the area being

sprayed.

Flow, size and distribution vary according to the air volume generated by the fan. Therefore,

always work as directed in the operator's manual.

Dosageunit

PTO SHAFT

The PTO shaft has plastic protection guards to prevent the rotating male and female tubes fromtouching the operator or his clothes, thus reducing the accidents, as well as from damaging the crop.

Also, at the end that is connected to the sprayer there is a unlocking system to relieveovercharges in the transmission.


SPOUT CAPThis cap is designed to prevent insects or

birds from making their nests in the spout. Unlockit before starting to spray; it will be kept openby the own air flow, without hindering the spray.

After finishing the spray application, lock thecap again.

FAN HOUSING COVERThis cover is specifically designed to allow to

clean the fan housing; just unscrew it.ATTENTION: Always clean the fan housingbefore mounting the sprayer to the tractor toavoid any kind of damage.

After cleaning, re-install the cover.

CHOOSING THE IDEAL TRACTOR

12

PROCEDURE

- Check the sprayer weight in the sprayer's identification plate.

- Check the capacity of the sprayer's tank.

- Check in the technical specifications table the total power consumption required.

Example:

- Sprayer weight = 507.15 lb

- Tank capacity = 105.68 gallons

- Total power consumption = 14.5 HP

1- Considering the power consumption

The tractor's engine power must be at least 90% higher than the power required to run the

sprayer.

Example:

- Power required by the sprayer = 14.5 HP

- Tractor recommended: with minimun nominal power of 27.5 HP

2- Considering the lift capacity of the hydraulic system

The lift capacity of the tractor's hydraulic system must be higher than empty sprayer weight

added to the weight equivalent to the tank capacity.

Example:

- Empty sprayer weight ................ 507.15 lb

- Tank capacity ........................... 105.68 gal (approximately 882 lb)

- Tractor recommended: with lift capacity of hydraulic system higher than 1,389.15 lb.

ATTENTION

The figures above are specifically mentioned in order to direct you on how to

proceed to choose the ideal tractor to which you are to mount your sprayer.

LEVELLING BOXTo adjust the transversal levelling of the sprayer, turn the crank (1) located on the levelling

box.

ADJUSTING THE THIRD POINTRelease the lock (1) and turn the sleeve (2) to adjust the length of the third point arm. During

transport, fasten the plate of the third point bar to the pin (3) of the frame.

- Adjust the tractor's hydraulic lift lever so

that the sprayer is not raised too high.

- Remove or pull the tractor's drawbar

aside.

- Adjust the PTO shaft. If necessary, cut

the male and female tubes so that, after

connecting the sprayer, it has the overlaps

recommended in the figure beside.

ATTENTION

Before cutting the tubes, check for all possibilities of movement of the sprayeron the lift arms and third point.

Make sure the hitch pins locks are correctly installed.

A successful spray application does not depend only on a good sprayer or correct use of thechemicals but also on factors to be determined in the field under specialized orientation.

Among these factors, some concepts should be part of a criterion of evaluation so that positiveresults may be attained within the pest control program.

- Ideal time - Application rate

- Safety - Good coverage

- Sprayer operational condition - Well trained operator

IDEAL TIME

The ideal time for spraying should be chosen according to the chemical product characteristics,as well as to the field conditions:

- Infestation level of pests, diseases and weeds;

- Infection level of diseases;

- Growing stage of weeds;

- Weather conditions.

SAFETY

When spraying your crops, you must make sure there will be no risk to people, animals andenvironment. Avoid spraying at hotter times, with humidity below 55% or under windy conditions.Do not allow the operator to handle chemicals and spraying machinery without the properindividual protective clothing.

CORRECT APPLICATION RATE

Any type of application requires that the rate be maintained during the whole spraying work. Thiswill be possible when you have a good sprayer properly calibrated.

This calibration can be obtained through practical methods or formulas. Please refer to thesection OPERATION AND ADJUSTMENTS - CALIBRATING THE SPRAYER .

GOOD COVERAGE

You have a good coverage when the whole target is sprayed with uniform distribution, with no riskto the environment and with good results in the pest control.

The application rate does not have influence on the treatment results. Therefore good coveragescan be attained even with different rates, which may vary according to operational and regionalfactors.

IMPORTANT!READ CAREFULLY AND FOLLOW STRICTLY THE INSTRUCTIONS ON THE

CHEMICALS MANUFACTURER'S LABEL.ALWAYS FOLLOW DIRECTIONS OF A TECHNICIAN WHEN HANDLING AND

APPLYING CHEMICALS.ALWAYS MAKE SURE THE SPRAYER IS IN GOOD OPERATIONAL CONDITIONS

ATTENTION

The figures shown in the example above are illustrative only. The correct calibration

must be done according to the recommendations of technician.


SPRAYER CALIBRATION

The safety of people, animals and environment depends on correct spray applications. Therefore,we list below important operational procedures.

WHEN HANDLING CHEMICALS

- Follow strictly the instructions on the labels.

- Use individual protective clothing recommended.

- Do not eat, drink or smoke.

- Choose a ventilated place.

- Wash with water and soap the parts of the body

touched by chemicals.

WHEN OPERATING SPRAYER

- Check for the proper working conditions of the

sprayer.

-Do not blow by mouth nozzles, valves or tubes.

-Do not spray against the wind.

-Do not spray at sunny times

-Use individual protective clothing recommended.

- Do not eat, drink or smoke.

REMEMBER!You are responsible for the success of the application.

PROCEDURE

The calibration of the sprayer can be done by calculating the the spray volume through the

following formula:

Where:

V - Spray volume (gpa)

F - Total nozzles flow rate (gpm)

A - Spray swath (ft)

S - Tractor speed (mph)

DETERMINING THE SPOUT FLOW RATEDifferent flow rates can be obtained through setting of the flow rate regulating valve, as well as

through shifting of dosage unit on the main spout and dosage cell on the auxiliary rotary atomizer.

PROCEDURE- Choose an even ground and level both the sprayer and spout.- Fill the tank and mark the water level.- Set the flow rate regulating valve and run the tractor with 540 rpm at the PTO.- Spray for one minute and again fill the tank up to the level previously marked and note the quantityof water sprayed.- Repeat this operation several times and take the average.

ATTENTIONTO INCREASE THE VOLUME:- Raise the setting of the flow regulating valve.- Reduce the spray swath.- Reduce the tractor speed (keep 540 rpm atthe PTO).
