General safety recommendations
> Transportation safety
ARBUS 500
• Before starting transportation, it is very
important that the path over which the
equipment will pass be carefully studies
and that the agencies regulating such method of transportation be consulted regarding the precautions and current legislation.
• All highways, roads, local roads, ways
and streets whose utilization characteristics are influenced by natural factors (climate, growth of tree without man's actions,
etc.) and construction (material employed,
height of bridges, nearness of electric networks, roadway width, etc.). Such characteristics shall be carefully evaluated prior to
transportation of the equipment.
• If in doubt, do not transport the equipment. Hire a company specialized in that
kind of service.
• Wash the equipment on the outside after its use. Even if it appears to be clean,
the ropes employed for fastening the equipment shall not be used again for binding
foodstuff; they may be contaminated and,
accordingly, contaminate such foodstuff.
• Make use of the PPEs when tying the
equipment. If necessary, make a combined
use of the mandatory PPEs for tying the
equipment and the mandatory PPEs for application of the chemicals. That combination will reduce the risks of contamination
during fastening of the equipment.
• Equipment fastening to the cart or truck
shall be performed by the tying points (see
figure below). Any tying carried out at random, while appearing to be safe and secure, is extremely dangerous and can cause
serious accidents. If in doubt, contact Jacto.
CHAPTER 1 - PRECAUTIONS
• Make sure that the chemical circuit has
been washed and that the chemical reservoir has been entirely drained after such
washing. Spill of setup leftovers, although
minimal, can endanger the life of people,
animals and cause serious damages to the
environment.
17
ARBUS 500
Safety for unloading the equipment
• Unloading shall take place at spots specifically created for unloading such type of
equipment. Do not improvise for unloading the equipment.
• Wear the PPEs during removal of the ropes fastening the equipment to the cart. If
the equipment is not new, make use of a
CHAPTER 1 - PRECAUTIONS
combination of the mandatory PPEs for unloading the equipment (e.g., safety boots,
gloves, hardhats, etc.) and mandatory PPEs
for chemical spraying (e.g., masks, gloves,
etc.) in order to reduce the risk of contamination and accidents.
• For unloading the equipment, use a tractor having the capability to carry out such
task. Selection of the tractor shall take into
account its drag capacity and spraying mechanism weight.
• Do not untie the mobile parts of the
equipment, for instance: PTO shaft, before
unloading the equipment down from the
truck or cart and position it on a safe place.
• After placing the equipment on a safe
place and far away from electric mainlines,
reset the jack to its rest position and uncouple the equipment from the tractor.

ARBUS 500
Safety when applying chemicals
1 • READ the sprayer instructions manual.
For an efficient spraying operation, it is
necessary to know the sprayer employed in
detail. Only thus will we prevent wasting
chemical or improper use of the equipment,
and the desired result will be achieved.
2 • Proper SETTING of the sprayer is a sim-
ple operation. Only with the sprayer pro-
CHAPTER 1 - PRECAUTIONS
perly set will the best results be achieved.
3 • USE approved, recommended and sui-
table protection equipment (PPEs). During
handling, setup of the mixture or spraying,
use all protection equipment recommended by the chemical manufacturer.
After the spraying operation, take a shower
and change clothing. The used clothing
shall be immediately washed and segregated from the regular use clothing to eliminate the chemical residue. In case of contact with chemicals, wash the affected part
with running water for at least 15 minutes.
Remember: most contamination cases
occur at the time of setup of the mixture,
where the chemical is still concentrated,
and gets in contact with the hands.
If the manufacturer of the product to be
used recommends using a breather mask
during application, use it!
4 • KEEP the sprayer in perfect condition:
Make sure that no leaks exist. If detected,
eliminate the same! Leaks not only represent
chemical waste but also uneven application
and contamination of the environment.
5 • USE the appropriate nozzle: There is
an appropriate nozzle for each chemical
to be applied. Climate conditions will also
influence nozzle selection. The mixture
volume varies from one chemical to
another one. The chemical manufacturer
should be consulted for the optimum
nozzle option.
22
Do not enter with or keep inside the
tractor cab the personal protection equipment (PPEs) used during handling or
setup of the mixture in order not to contaminate the place. When inside the tractor cab during operation of the machine
and/or spraying operation, use only an
ear protector. If noticing that contamination has occurred (if feeling chemical
smell) caused by carelessness in working
with the door open or letting contaminated materials coming in (e.g.: PPEs), use
immediately an approved and suitable
breathing mask and contact Jacto's Technical Assistance;
Safety when applying chemicals
ARBUS 500
6 • DO NOT clear nozzles, vales or tubing
with your mouth: Use protection gloves
for this operation. Any spraying equipment
contains chemical residue.
Never let sprayer parts contact your mouth;
this is the fastest means of contamination.
If need arises to clear the nozzles, one
may also employ a nylon bristle brush
(toothbrush).
7 • DO NOT contaminate water sources:
The spraying mechanism refill shall be
performed at places designed for that
purpose or by means of appropriate
refilling vehicles (trucks, carts, etc.).
Avoid capturing water from sources
such as rivers, lakes, dams, creeks, etc.
with the aid of the sprayer return system.
PRESERVE THE ENVIRONMENT!
CHAPTER 1 - PRECAUTIONS
8 • DO NOT eat, drink or smoke: when
handling the mixture or during application
of the chemical, keep foodstuff far away
from the treated areas.
9 • KEEP children away from the
sprayed areas. Remove children, domestic
animals and unprotected people from the
treated areas. Do not allow children or
other persons not necessary for the services
to remain in the chemical handling and
application areas.
10 • APPLY the recommended dosages:
The dosages recommended by the
manufacturers shall be followed. Any
change to the dosage or calculation error
may bring about serious consequences to
the cultivation or the environment. Do not
use chemicals in cultivations which the
same have not been recommended for.
23
ARBUS 500
11 • DO NOT spray with strong winds
blowing over the area: Excess wind can
cause many problems. It will prevent the
chemical from reaching its target, causing
a poor distribution of chemical over the
cultivation; it can also carry the sprayed
mixture to water springs, wild animals and
the entire environment. Do not spray if
CHAPTER 1 - PRECAUTIONS
the wind velocity is higher than 6 mph .
Do not spray in the absence of winds. Such
a situation can cause a thermal reversal.
A good application can be obtained with
winds blowing at 2 to 4 mph velocity,
temperature from between 44 and 86°F
and relative air humidity over 55%. Do not
spray against the direction of the wind or
during the day warmest hours.
Safety when applying chemicals
12 • WASH the packaging before disposing
the same. When preparing the mixture,
wash the used packaging for about 30
seconds.
13 • TO NOT reuse empty packaging;
Even after several washing operations,
chemical packaging still retain residue. Do
not burn empty packaging material. After
washing, render the same unusable (pierce
the packaging bottom) and store it at a
safe place until the same are picked up ad
recycled.
14 • NEVER fill the sprayer to the top. By
doing so, you will prevent the mixture from
overflowing and possible contamination of
the operator and the environment. When
supplying the reservoir, do it up to the
maximum limit indicated in its graduated
scale.
24
Safety when applying chemicals
ARBUS 500
15 • When CARRYING chemicals: Never
carry them close to foodstuff or animal
feed. Never buy packaging exhibiting leaks.
Never buy or use chemicals past their shelf
life. Never carry chemicals inside the cab. If
an accident occurs causing chemical spill,
take steps towards preventing the chemical
from running into lakes or rivers. Notify the
authorities and the chemical manufacturer.
16 • STORING THE CHEMICAL: Build a
brickwork storehouse for chemicals.
• Line the floor with waterproof material.
Do not rest the product piles on the floor
or against walls. Use a footboard. Keep at
the place a drum with sand to absorb leaks,
if any. Install faucet and shower outside the
storehouse for the chemical appliers.
CHAPTER 1 - PRECAUTIONS
17 • SYMPTOMS of intoxication:
unconsciousness, anxiety, convulsions,
weakness, headache, indisposition,
dizziness, blurred vision, qualms of nausea,
vomits, belly ache, diarrhea, urine with
different color and consistency; eye, nose
and throat irritation, cough and tears.
18 • FIRST aid: if the victim vomits, let him/
her stay sitting. Never serve any alcoholic
beverage or milk to intoxicated (poisoned)
persons. Keep the victim calm and in a
comfortable position. Find the chemical
label. Call a doctor.

• Lubricating oil filters and oils shall be
checked from time to time and changed
whenever necessary or recommended.
• Every maintenance service on hydraulic
tubing or hoses shall be performed after
de-pressurization of the circuit. Redouble
your warning during this kind of maintenance.
• The identification of spots exhibiting possible leaks shall be made with paper, never with the hands.
• With the equipment coupled to the tractor and the PTO, be careful and keep away
from the moving parts of the equipment;
these must be provided with their respective protections. In case of doubt, call the
authorized technical assistance.
• In case that no possibility exists of providing maintenance service to the equipment with the diesel engine shut down and
outside sheds, keep the shed doors and
windows wide open to allow continuous
circulation of air. Internal combustion engines running within closed environments
cause toxic gases and can asphyxiate the
operator within a few minutes.
• Performance of cleaning, lubrication and
maintenance services with the machine
running is forbidden, unless such running
condition is indispensable for the performance of such operations, in which case
special protection and signaling steps shall
be taken against occupational accidents.
• Welding services on bars, chassis or other

CHAPTER 2 - ASSEMBLY
1
Choosing the tractor
ARBUS 500
The different working standards encountered by agricultural equipment leads us to
comply with the following criteria when
choosing a tractor for products of Jacto Arbus 500 and Arbus 500 Grape sprayers.
• Check the weight of the machine (lb) on
the identification plate of the product.
• Check the capacity (in gallons) of the backup reservoir.
> Choosing the tractor considering the 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 = 8.1 HP
Example:
Empty machine weight = 768.80 lb
Reservoir capacity = 151.90 + 13.20 + 3.96
= 169.07 gallons
Total cower consumption = 8.1 HP
CHAPTER 2 - ASSEMBLY
Tractor recomended: Minimum tractor nominal power = 15.4 HP
> Choosing the tractor according to the lift capacity of the hydraulic system
• Choose tractors whose gross mass is, at least, equal to the sum of the empty weight of the
machine plus the weight equivalent to the capacity of the reservoir.
Example: Empty machine weight = 762.80 lb

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 must always remain open
while the sprayer is running. If it remains
closed, you will hear an unusual noise in
the pump.

Spray application technology
• The success of an application not only
depends of good equipment and correct
use of chemicals. Depends also on field
factors, such as specialized orientation.
• Among these factors, we consider some
concepts that should be part of an evaluation criteria so that the positive results are
reached within a chemical control program
of biological agents (diseases, plagues and
weeds).
> Right moment
CHAPTER 4 – OPERATION AND ADJUSTMENTS
Consists in choosing the ideal moment according to the characteristics of the chemicals and also field conditions, such as:
• Level of plague infestation, diseases or

> Safety during application
• The maintenance of safe conditions for
people, animals and the environment is
fundamental. The use of personal protective equipment is mandatory during the
application of the chemicals.
> Correct dosage
• It is fundamental, for any type of application, the correct maintenance of the
chemicals dosage for the duration of the
spraying process.
• This is possible if good equipment is available and the chemicals is correctly calibrated before starting the application.
• Avoid applying when temperatures are
0
above 86
F (depending on the chemical
product) and relative air humidity lower
than 50%, winds with unpredictable speeds ( maximum velocity 6 mph) and direction.
• The calibration can be obtained thru
practical methods or via calculations (refer
to the instructions regarding the sprayers
calibration, which can be found on the
“CALIBRATION OF SPRAY” page).
Spray application technology
Goodcoverage
>
ARBUS 500
• A good coverage consists of obtaining
ideally sized drops to reach the target with
good uniform distribution, with positive results during control and that do not cause
damages to the environment.
• Unlike what a lot of people think, the
application volume does not influence
the treatment result, since the amount of
solvent (water, oil, etc) per unit area only
functions to dissolve, transport and facilitate the distribution of the active ingredient
over the target surface, whether it is plants,
soil, etc.
ATTENTION!
Read and rigorously follow the instructions contained in label of the chemical
products.
Always follow the orientation of a technician or someone responsible for the
operation during the handle and use of chemical products.
• This means that one could get the same
coverage with different spraying volumes.
• In practice, different volumes have been
used for the same ends due to operational
as well as regional factors.
