MAIN COMPONENTS OF SPRAYER
SUCTION FILTER
Located between the tank and pump, the suction filter is specifically designed to prevent dirt or impurities from reaching the pump.
It has a quick shut off valve which allows easy filter cleaning, filtering elements changing and/or pump maintenance. This valve also directs the water flow from the main or auxuliary tank to the pump.
This valve must always remain set to the main tank when the sprayer is running. If it remains closed, you will hear an unusual noise in the pump.
To turn on and off the flow or to deviate it between the main and auxiliary tanks, just turn the valve maintaining the lever indicator arrow as shown below.

CHOOSING THE TRACTOR
PROCEDURES
Different working conditions lead us to adopt the following criterion for choosing the tractor that will drive the Arbus line sprayers with tank capacity of 264.17, 396.25 and 528.34 gallons.
- Check the sprayer weight on the identification plate.
- Check the tank capacity.
- Check in the specifications table the total power consumption of the sprayer at the PTO.
Example:
Sprayer weight = 1,455.04 lb
Tank capacity = 396.25 gallons
Total cower consumption = 38.7 HP
CHOOSING THE TRACTOR CONSIDERING
THE POWER CONSUMPTION AND THE LOAD TO BE TRANSPORTED
1st - POWER CONSUMPTION
The tractor should have power (HP) at least 90% higher than the power required to run the sprayer.
Ex.: Power required by the sprayer = 38.7 HP
Minimum tractor nominal power = 73 HP
2nd - LOAD TO BE TRANSPORTED
The tractor gross weight should be at least equal to the sprayer gross weight (sprayer net weight plus full tank weight).
Ex: Sprayer net weight = 1,455.04 lb
Full tank weight = approximately 3,306.93 lb (396.25-gallon tank)
Sprayer gross weight = 3,306.93 lb
Tractor gross weight = 4,761.97 lb or more
ATTENTION
In this case the recommended tractor should have minimal nominal power of 73 HP and weigh at least gross 4,761.97 lb.
NOTE:
The above values are used as an orientation. The correct values must be obtained using real data of yor equipment.
25
SETTING UP THE TRACTOR
- Adjusting the drawbar
Fit the drawbar pin into the proper hole (1 or 2) to vary the distance between the PTO shaft and the hitch point (see figure A).
NOTE:
For heavy load, the hole no. 2 is recommended (see figure A).

NOTE
In order to know what is the approximate weight (lb) put on the tractor drawbar when hitched to Arbus line sprayers, just add the sprayer weight to the tank capacity and multiply the total by 0.12.
26
CONNECTING THE PTO
WIDE-ANGLE CV PTO SHAFT (WITH CV JOINT)
- Adjust the drawbar length in relation to the PTO as shown in the figure beside.
IDEAL CONNECTION
- The distance A must be as long as possible and the B as short as possible. This provides a wider angle to the CV joint.
The ideal is to have A = two times B.
Hitch the sprayer to the tractor.
B

OPERATION AND ADJUSTMENTS
SPRAY APPLICATION TECHNOLOGY
A successful spray application does not depend only on a good sprayer or correct use of the chemicals 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 positive results may be attained within the pest control program.
- Ideal time
- Safety
- Application rate
- Good coverage
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 and environment. 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 proper individual protective clothing.
CORRECT APPLICATION RATE
Any type of application requires that the rate be maintained during the whole spraying work. This will be possible when you have a good sprayer properly calibrated.
This calibration can be obtained through practical methods or formulas. Please refer to the section OPERATION AND ADJUSTMENTS - CALIBRATING THE SPRAYER.
GOOD COVERAGE
You have a good coverage when the whole target is sprayed with uniform distribution, with no risk to the environment and with good results in the pest control.
The application rate does not have influence on the treatment results. Therefore good coverages can be attained even with different rates, which may vary according to operational and regional factors.
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
BEFORE STARTING THE SPRAYING JOB AND EMPLOY A WELL TRAINED
OPERATOR.
28
OPERATION AND ADJUSTMENTS
CHEMICAL CONTROL
The pressure regulator control provides adjustments that ranges from 2 to 35 kgf/cm² (30 to 500 psi), shown in the pressure gauge.
The levers (1), (2), and (3) have different functions: lever (1) turns the chemical flow on and off, and levers (2) and (3) distribute the chemical flow to the left and right nozzle branches, making the spraying easier and more economical.

OPERATION AND ADJUSTMENTS
CALIBRATING THE SPRAYER
The safety of people, animals and environment depends on correct spray applications.
Therefore, we list below some operational procedures.
WHEN HANDLING THE CHEMICALS
- Follow strictly the instructions on the labels.
- Use individual protective equipment.
- Do not eat, drink or smoke.
- Choose a ventilated place.
- Wash with water and soap the parts of the body touched by chemicals.
WHEN HANDLING THE 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 in hotter times.
- Use individual protective clothing recommended.
- Do not eat, drink or smoke.
REMEMBER
You are responsible for the success of the application.
PROCEDURE
The sprayer can be calibrated by obtaining the spraying volume through the following formula:
GPA =
GPM x 495
MPH x S
Where:
GPA : Application volume in gallons per acre
GPM : Application volume in gallons per minute
MPH : Tractor speed in miles per hour
S : Row spacing width in feet
495 : Conversion factor
EXAMPLE:
Total nozzles flow rate: (14 x J4-2 nozzles & 12 x J4-3 nozzles at 200 psi) = 14.37 gpm
Row spacing: 16.4 x 22.96 (ft)
No. of trees per acre: 115 trees
Tractor speed: 2.5 mph
GPA =
GPM x 495
MPH x S
GPA =
14.37 x 495
2.5 x 22.96
GPA =
124 gallons per acre
SPRAYING VOLUME PER TREE:
124
115
= 1.07 (gallons/tree)

52
MAINTENANCE
TROUBLE-SHOOTING
a - LACK OF SUCTION AND PUMPING CAPACITY
PROBABLE CAUSES
1- PTO not turning.
SOLUTIONS
The sprayer should be run with 540 rpm at PTO. Check visually whether the pump is being run.
2- Lack of water in the tank.
To run the hydraulic system, it is necessary to contain a minimum quantity of liquid, otherwise there will be no pressure.
3- Filter shut off valve closed.
4- Dirty filter.
5- Obstruction in the intake hoses.
6- Air in the system.
When the pump runs, liquid will pass through the valve even in the closed position, however it will be insufficient. Open it.
Impurities in the filter prevent a free liquid flow. Clean the filter whenever filling the tank, or with more frequency depending on the quality of the water and the type of product applied.
Check whether the hose connecting the filter to the pump is twisted.
Check whether there is any obstruction in the hoses from tank to filter. Fill up the tank with water, open the valve and verify if it flows freely.
Check the filter packing ring. The filter should not leak.
7- Insufficient pump suction.
Remove the cover of the suction valves.
Check the condition of the valves and replace them if necessary.
b - PRESSURE DEFICIENCY
PROBABLE CAUSES
1- Low PTO rpm.
SOLUTIONS
The proper PTO rotation is 540 rpm.
2- Filter shut off valve closed.
3- Filter partially obstructed.
4- Intake hose partially obstructed.
5- Air in the system.
6- Pressure regulator.
7- Worn nozzles.
8- Pump with lower flow rate.
When the pumps runs, liquid will pass through the valve even in the closed position, however flow will be insufficient.
The filter should be clean to allow free liquid flow.
A deficient pump will cause depressurization. Check whether the hose connecting the filter to the pump is twisted.
Verify whether there is any obstruction in the hoses connecting the tank to the filter. Fill the tank with water, open the valve and observe if it flows freely.
Check the connections and the o'rings of the tank outlet and the pump inlet.
Check the valve and valve seat.
Check whether the nozzle flow is within the recommended guidelines.
Replace the nozzles when the flow rate exceeds 10% of the specified.
Use only nozzles recommended by the sprayer manufacturer.
Disconnect the pressure hose from the control valve.
Run the sprayer at 540 rpm.
Collect water for one minute and measure. The volume collected should approximate this shown below for each pump model:
JP - 402 = 10.04 gpm
JP - 42 = 11.09 gpm
JP - 75 = 19.81 gpm JP - 300 = 79.25 gpm

2- Air in the intake system.
3- Pressure regulator.
SOLUTIONS
Check belt tension and tighten if necessary.
Check for damaged hoses, filter packing rings, etc., and repair if necessary.
Check the regulator components and clean or replace them if necessary.
d - INTERMITTENT PRESSURE
PROBABLE CAUSES
1- Valve closed
2- Pump valve deficiency
3- Pump head perforated internally.
INDICATIONS AND CORRECTIONS
When the pump runs, liquid will pass through the valve even in closed position, however flow will be insufficient.
Valve with sealing deficiency or stuck due to impurities.
Replace it.
