- After spraying, carefully wash the mist blower
diluting residual with a quantity of water at
least 10 times higher than residual, and
redistributing the obtained mixture on the
treated field.
- Intensify control of the state of the membrane
after using aggressive chemical products;
accurately wash the complete system after
using copper hydroxide.
- There must be a supply of clean water on hand
near the site where the treatment is being
carried out.
PRECAUTIONS AGAINST FIRE
Do not approach the mist blower with fire or heat
sources.
METEROLOGICAL CONDITIONS
It is advised to treat early in the morning or in the
latter part of the afternoon avoiding the warmer
hours of the day.
Never treat before or while raining.
Never treat with strong wind or with winds
higher than 3/5 meters per second.
REGULATOR OF THE LIQUIDS FLOW
On the throwing pipe (12, Fig.1) is present the
liquid tap (A, Fig.4) that allow the opening and
the closing of the liquid flow toward the exit.
The liquid flow rate is set by the regulator (B,
Fig.4).
Rotate the spreader (B, Fig.4) clockwise or
counterclockwise sense to select one of the 9
positions desired.
Please refer to the following table that give
an indication about the liquid flow in the ten
positions of the regulator. Please note that:
· The flows are calculated with the engine at
full throttle (max RPM), the throwing pipe in
horizontal position and using clean water;
using liquids with a different density the flow
can change.
· These flows are only an indication; we suggest
the use of ULV attachment if you need an
accurate dosage of the chemicals.

The mist blower MB90 / AT900 is designed in
order to perform treatments with the same
efficacy even with the throwing pipe oriented in
the vertical direction; to make more comfortable
such treatments, the machine is equipped with a
rotating elbow (9, Fig.1).
FILLING OF THE LIQUID TANK
To fill the liquid tank:
· Place the machine on the ground in a smooth
site.
· Verify the closing of the liquid tap (A, Fig.4)
presents on the throwing pipe.
· Unscrew the cap of the liquid tank by rotating
it in counterclockwise sense.
· Check the correct position of the blue sieve
with a filtering mesh of 50/60 micron.
· Spill the product into the tank through the
sieve.
· If the user of the machine is a man, be careful
to not exceed the mark of 16 liters present on
the tank. If the user of the machine is a woman,
the mark to be respected is that of 11 liters.
· It is possible to fill the liquid tank till its
maximum capacity of 17 liters but, to respect
the peak load's weight (men), in the mixture
tank must not be more than a liter of fuel
(approximately half tank).
· Close the cap of the tank by rotating it in
clockwise sense.
WARNING - Respect the level of permissible
maximum weight. The markings on the tank
show the level limits that should be observed so
as not to exceed recommended weights: 30 kg
for men, 20 kg for women. This weight is the sum
