TIGHTENING
Hold the strap buckle firmly with one
hand, and pull the handle downward
with the other hand.
LOOSENING
Hold the buckle firmly with one hand,
and pull the strap upward with the
other hand.
5∙ Continue holding the container over
the spray tank opening for approximate-
ly 30 seconds or until it stops dripping.
6∙ REPEAT this operation twice more.
Thiswayyoucompletethe TRIPLE WASH.
7∙ Make the plastic and metallic
containers useless by piercing the con-
tainers bottom with a pointed instru-
ment. By doing this the labels are not
damaged for identification purposes.
8∙ The useless containers can be
stored temporarily in an appropriate
place, until final destination.
9∙ With mid and large size container
(15, 25 and 50 gallons), add appropriate
volume (1/4 of the total) of water and
install the cap, roll it on the ground for
approximately 30 seconds.
10∙ Next in the upright position com-
plete the agitation by moving back and
forth for approximately 30 seconds.
11∙ Then, empty the container by
pouring the rinse water into the spray
tank.
12∙ REPEAT this operation twice more.
At the last time, completely empty the
containers rinse.
13∙ The least amount of rinse water
that remains in the container, from one
wash to the next, the better descontami-
nation will be.
14∙ When performing the TRIPLE
WASH, do not use a water volume
either much lower or much higher than
1/4 of the container capacity.
15∙ The TRIPLE WASH must be done
IMMEDIATELY AFTER emptying the
container, during the preparation of the
solution.

The tank is contoured for the operator
comfort. The shoulder straps can be
quickly adjusted to properly position the
sprayer on the operator's back.
> Adjusting the shoulder strap
ATTENTION!
After assembling the sprayer, fill the tank with clean water and
pressure-check the tank lid, diaphragm, tank bottom, lance and tri-
gger valve for leaks. Most leaks can be stopped by retightening the
appropriate connections and fittings. Any leakage must be repaired
before returning to service .

Maintenance

Triple wash containers
Filter assembly
Filter
After finishing the application, clean and wash all equipment in an approved de-
contamination area.
Every 40 hours, clean and lubrica-
te the chamber and components,
as shown. Remove the cham-
ber and lubricate the piston cups.
Jacto recommends graphite base
grease but silicone based grease or
vaseline are also acceptable. Do not
apply grease excessively to avoid
clogging and impurities build-up.
Even the containers considered empty,
still contain chemical residues. Some
publications show that approximately
0.3% of the chemicals remains in the
container after being used.Therefore,
discarding the containers without
washing out the residues is extremely
dangerous to man, animals and envi-
ronment.
In the case of metal, plastic and glass
chemical containers, each container
must be rinsed three times to ensure the
residues are completely removed. This
manual describeds how to perform the
TRIPLE WASH in a correct, safe and
effective way.
During the TRIPLE WASH, you must use
appropriate protective clothing, such as:
gloves, apron, boots, goggles and pro-
tective masks with appropriate filters.
IMMEDIATELY AFTER emptying the
container, keep it upside down over
the sprayer tank opening or over the
bucket that you are using to prepare
the chemical mixture for at least 30
seconds or until no residue is left in the
container, when the drops are falling in
long intervals.
1∙ Next, hold the container in the
upright position and fill it with water.
For example: in a 4 gallon container,
put 1 gallon of water.
2∙ Fit the container cap and tight it
enough to avoid leakage during the
agitation.
3∙ Agitate the container strongly in all
ways (horizontal and vertical), during
approximately 30 seconds to remove the
residues that are stuck to the container
internal walls.
4∙ Carefully remove the container cap
andpourtherinse water intothespray tank.
> Triple wash of empty agrochemicals containers
ATTENTION!
Remove all chemicals before storing the sprayer. Chemical products
have different reactions and can damage the sprayer components and
environment as well as cause personal injury.

Maintenance
> Troubleshooting procedure
PROBLEM CAUSES CORRECTIONS
Leak on the upper portion of
the cylinder.
Worn or dried out piston
cup.
Replace or lubricate
the piston cup.
After pumping and pressuri-
zing the chamber the pumping
lever falls.
Cylinder valve not sealing
properly due to wear or
impurities.
Clean or replace the
valve.
After pumping and pressuri-
zing the chamber, the lever
rises slowly when released.
Chamber valve not sealing
properly due to wear or
impurities.
Clean or replace the
chamber.
Put about 0.5 gallon of water in the tank.
While operating the pumping lever, look
into the tank.
Refer to the table and diagram below.
Put 1 gallon of water in a bucket and
add the chemical product. Stir until it
becomes an homogeneous mixture and
pour the solution into the tank while
filling with water.
Carefully read the chemicals manufac-
turer's label.
Use of individual protective clothing and
safety equipment is recommended.
Do not eat, drink or smoke while spray-
ing.
Do not pollute the environment.
Keep all products out of reach of chil-
dren and animals. Lock up the chemical
products to prevent untrained persons to
handling them.
After finishing the spray application, take
a shower with plenty of water and soap.
Put on clean clothes.

Attach the calibrator bottle to the lance as shown:
Hold the lance at the working height and
spray to measure the application band
width. Based on the band width, calculate
the total walkingdistance required to spray
the desired area 269.1 ft2 .
A - Remove the cap, nozzle and filter.
B - Mount the calibrator cover to the
lance.
C - Reinstall the filter, nozzle and cap.
D - Screw the calibrator onto the
cover.
Hold the lance at the normal working
height and spray into the bottle while
walking the distance required to spray
an area corresponding to 269.1 ft2.
Place the bottle on a level surface
and observe the liquid level visible
through the side of the bottle. Match
the liquid level to the correspond-
ing scale on the calibrator bottle.
Empty the bottle and repeat this
operation to determine the aver-
age of two or more readings.
