and pull the handle downward with the other
hand.
Buckle
LOOSENING
- Hold the buckle rmly with one hand, and
pull the strap upward with the other hand.

11- ATTENTION
After assembling the sprayer, ll the tank with clean water and pressure-check the
tank lid, diaphragm, tank bottom, lance and trigger valve for leakage. Most leaks can
be stopped by retightening the appropriate connections and ttings. Any leakage must
be repaired before returning to service.
12- INVERTING THE LEVER POSITION
This sprayer is assembled to mount the lever for left hand operation. In case you wish
to change its position, proceed as follows.
- Remove the locked ring (1) and washers (A) and the rod (2) of the chamber top.
- Turn the chamber top 180°.
- Reinstall the rod (2) on the chamber top, t the washers (A) and secure the rod with
the locked ring (1) again.
- Then, remove the locked ring (4 and 5) and the washers (B).
- Remove the lever (6) and the shaft (7).
- Unfasten the strap assembly (8) and mount it on the other side of the sprayer as shown
in the detail below.
- Take the container cap off and carefully pour the rinse water into
the spray tank.
- Continue 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 use-
less by piercing with a pointed instrument the contai-
ners bottom. This way, their labels are not damaged
for identication purposes.
- The useless containers can be placed temporarily in an appropriate place, until nal destina-
tion.
- In the case of mid and large size container (13.2, 26.4 and 52.8 gallons), after washing with the
appropriate volume (1/4 of the total) and tting the cap, roll it on the ground for approximately 30
seconds.
- In the upright position complete the agitation by moving back and forth for approximately 30
seconds.
- Empty the container by pouring the rinse water into the spray tank.
- REPEAT this operation twice more. Finally, totally empty the container by pouring rinse water
in the spray tank.
- The least amount of rinse water that remains in the container, from one wash to the next, the
better the decontamination will be.
- 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

13- MAINTENANCE
CLEANING THE SPRAYER
- After nishing the application, clean and wash
all equipment in an approved decontamination
area.
Pump the lever until the dis-
charge runs clear.
ATTENTION: Remove all chemicals before storing
the sprayer. Chemical products have different re-
actions and can damage the sprayer components
and environment as well as cause personal injury.
- Periodically, clean the chamber and lubricate
the components as shown. With oil.
- Remove the chamber and lubricate the piston
cups. With oil.
Even the containers considered empty contain chemical residues.
Some publications show that aproximately 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 describeds 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.
- Next, hold the container in the upright position and ll it
with water up to 1/4. For example: in a 5.2 gallons
container, put 1.3 gallons of water.
- Fit the container cap and tighen enough to avoid leakage
during the agitation.
- Agitate the container vigorousty in all directions (horizontal and
vertical), for approximately 30 seconds to remove the
residues that cling to the container internal walls.

- Do not eat, drink or smoke while spraying. - Do not pollute the environment.
- Keep the pro-
ducts out of reach

ATTENTION: The clothing used during the application must be washed separate
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.
ATTENTION: In case of intoxication, see a doctor immediately and show
him the chemicals manufacturer's label.
