WARNING!
Do not spray near people who are not using PPE or near
springs, lakes or rivers.
9.14.5. Activate/Deactivate dosage lock
The Dosage Lock is a feature that allows the farm manager to lock the DJB in a
chosen dose volume and time interval. This avoids misuse of the equipment and
all users will apply the same dose volume with the same time interval thus gua-
ranteeing better application uniformity. Once locked, the dose is not changeable
when Green Button is pressed, nor when the sprayer is turned off, nor when the
battery is removed.
To activate the Dosage Lock:
1.
Select the desired dose volume and time interval (as shown before);
2.
Press the Green Button and keep it pressed during 15 seconds. When the
Dosage Lock is activated, all LED signs will briefly blink and the electrical
panel will emit a “beep”.
NOTE: The doser can still be turned off by holding the Red Button.
To deactivate the Dosage Lock:
1.
Press the Green Button three times and then press the Red Button once.
This must be done in less than 3 seconds. When the Dosage Lock is deac-
tivated, the electrical panel will emit a “bip”.
Wear appropriate protective clothing
Do not contaminate water

9.14.3. Possible time intervals
Liquid is dosed according to an adjustable time basis. Currently, doses can be dis-
pensed in time intervals of:
•
0.50 seconds, very fast dosing rate, tested in mountain coffee and nursery;
•
0.75 seconds, very fast dosing rate, tested in mountain coffee and nursery;
•
1.00 second, useful in mountain coffee and tobacco with irregular terrains;
•
1.50 seconds, same as above;
•
3.00 seconds, tested in non uniformly-spaced crops, such as banana;
Last used dose and last used time interval are saved when the electric panel is
turned off. So, it is not necessary to adjust equipment when you turn it on again.

9.14.4. Dosage calibration
Using the measuring cup (included in the box) you can calibrate your dosage to
improve your application.
Follow the steps below to calibrate your dosage:
•
Fill the tank with the pesticide mixture;
•
Select the proper dose in the electrical panel;
•
Increase the intervals between doses to 3 seconds to facilitate the dosage
collection;
•
If necessary remove air from hose;
•
Simulate the application by using the machine on your back and the measur-
ing cup where the pesticides would be sprayed on;
•
Release the trigger valve and apply 5 doses in the measuring cup;
•
Check the total volume and divide it by 5;
•
In case of the total doses overflows the cup, you can apply once, annotate the
volume, empty it and then repeat the process 5 more times;
•
Verifique se esta dose está de acordo com o esperado. Se não, aumente ou
diminua a dose no painel elétrico até encontrar uma dose adequada. Repita
a calibração;
•
Check if the result is according with the proper volume needed. In case it is
not, increase or decrease the dosage in the electrical panel until you find the
proper dosage. And repeat all this process.
You must repeat this calibration every time you change the type of mixture or
the pesticide concentration. Check regularly if the applied dosage is appropriate.
