8- ATTENTION
This equipment must be used only with products to protect plants approved for
knapsack sprayers
After assembling the sprayer, ll the tank with clean water and check for leakage on
the following parts.
LUBRICATION
Periodically, clean the chamber and lubricate
the components as shown.
Remove the chamber and lubricate the piston
cups.
ATTENTION:
Remove all chemi-
cals before storing
the sprayer. Chemical
products have different
reactions and can dam-
age the sprayer compo-
nents as well as cause
personal injury.
CLEANING THE SPRAYER
- After nishing the spray application, clean and wash all equipment in an approved
decontamination area.

10- CYLINDER VALVE MAINTENANCE
DISASSEMBLING
- Remove the chamber of the cylinder.
- Loosen the cylinder nut (1).
- Remove the cylinder (2).
- Use a screwdriver (*) to push the fastener out
of the cylinder. Do not use cutting or pointed
objects, which can damage the fastener.
- With the maintenance tool (*) (3), release
the valve by turning counterclockwise.
- Clean or replace the valve.
ASSEMBLING
- Mount the valve on the fastener.
- Fit the fastener in the cylinder. For proper
tting you must observe the channel/guide.
- Install the cylinder in the tank and tighten
the fastening nut (1).
- Install the chamber on the cylinder.

- Take the container cap off and carefully pour the rinse water into
the spray tank.
- Keep holding the container over the spray tank opening
for approximately 30 seconds to the last drop.
- REPEAT this operation twice more. This way, you complete the
TRIPLE WASH.
- Next, make the plastic and metallic containers
useless by piercing with a pointed instrument the
containers bottom. This way, their labels are not
damaged for identication purposes.
- The useless containers can be stocked temporarily in an appropriate place, until nal destina-
tion.
- In the case of mid and large size container (50, 100 and 200 liters), after washing with the ap-
propriate volume (1/4 of the total) and tting the cap, roll it on the ground during approximately
30 seconds.
- Then in the upright position complete the agitation by moving back and forth for approximately
30 seconds.
- Then, empty the container by pouring the rinse water into the spray tank.
- REPEAT this operation twice more. In the last one, empty totally the container by pouring rinse
the water in the spray tank.
- The least the quantity of rinse water that remains in the container, from one wash to the next,
the most perfect and complete will be the decontamination.
- For the performance of the TRIPLE WASH, do not use a water volume either much lower or
much higher than 1/4 of the container capacity.
-The TRIPLE WASH must be done IMMEDIATELY AFTER emptying the container, during the
preparation of the solution
SOURCE - ANDEF (NATIONAL ASSOCIATION OF VEGETAL DEFENSE)
(*) Items not supplied with the product.

Even the containers considered empty contain chemical residues.
Some publications show that somewhere around 0.3% of the chemicals remains in the
container after being used.
Therefore, discarding the containers without washing out the residues is extremely dan-
gerous to man, animals and environment.
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 describes how to make 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 protective masks with appropriate lters.
- IMMEDIATELY AFTER emptying the container, you must keep it with
the opening 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, until no residue is left in the container, when the drops are
falling in long intervals.
- Next, hold the container in the upright position and ll it
with water up to 1/4. For example: in a 20-liter container,
put 5 liters of water.
- Fit the container cap and tight it enough to avoid leakage
during the agitation.
- Agitate the container strongly in all ways (horizontal and
vertical), during approximately 30 seconds to remove the
residues that are sticked to the container internal walls.
14- TROUBLESHOOTING
- Put about 2 liters of water in the tank.
- While operating the lever, look into the tank to see how the problem arises.
- Refer to the table and diagram below.

from other clothes of ordinary use.
- After nishing the spray application, take
a shower with plenty of water and soap.
- Put on clean clothes.
- Lock up the chemical products to prevent
untrained persons to handle them.

him the chemicals manufacturer's label.
CALIBRATION OF MANUAL KNAPSACK SPRAYER
PROCEDURE
USINGCALIBRATORBOTTLE (OPTIONAL)
- Hold the lance at the working height and
spray to measure the application band width.
- Based on the band width, calculate the total
walking distance required to spray the desired
area. Use the chart below.

- Attach the calibrator bottle to the lance as
shown:
A - Remove the cap, nozzle and lter.
B - Mount the calibrator cover to the lance.
C - Reinstall the lter, 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 25 m².
- 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 corresponding scale on the calibrator bottle.
- Empty the bottle and repeat this operation to determine the average of two or more
readings.
