To deactivate the Pressure 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 Pressure Lock is deac-
tivated, pressure level indicator will stop blinking.
9.11. Set up walking pace timer
The Walking Pace function is a useful timer that can assist user to calibrate the
sprayer or keep a uniform walking speed while spraying. When the Walking Pace
function is activated, user will notice an audible beep, indicating the correct mo-
ment to step forward (as an example). The audible beeps can be used for other
purposes, such as spot chemical application. In this case, the beep can indicate the
While operating the sprayer, the possible audible/visible warnings can occur, in
To turn off the sprayer:
1.
Shut off the trigger valve. The internal pump pressure switch will automat-
ically turn off the pump (the sprayer is said to be in idle state). However,
the electronic interface will remain on.
2.
Press the Red Button and hold it pressed for 3 seconds. All lights in the
electronic interface will be off.
3.
Direct the spray lance to a safe position and open the trigger valve to re-
lease pressure before storing the sprayer.
4.
Remove and store the battery pack in safe place.
9.10. Activate/Deactivate pressure lock
The Pressure Lock is a feature that allows the farm manager to lock the sprayer in a
chosen pressure level. This avoids misuse of the equipment and all users will spray
with the same pressure level thus guaranteeing better spray uniformity. Once
locked, the pressure level is not changeable when Green Button is pressed, nor
when the sprayer is turned off, nor when the battery is removed.
To activate the Pressure Lock:
1.
Select the desired pressure level (1 to 5).
2.
Press Green Button and hold it pressed for 10 seconds. When Pressure
Lock is activated, pressure level indicator will blink.
NOTE: The sprayer can still be turned off by holding the Red Button.
NOTE: If the sprayer is left in idle state for more than 10 minutes, the electronic
interface will turn off automatically.

To remove the battery:
1.
Press both locking buttons;
2.
Pull the battery out of the
battery housing.
9.7. Installing and removing the battery
To install the battery:
1.
Locate the battery housing, on the bottom of the sprayer’s base, as shown
in the figure.
2.
Identify the correct battery position according to the position guides. Do
not force to install the battery in the wrong position.
3.
Press the battery until a “click” is heard.
9.8. Electronic interface, audible and visual warnings
The following picture shows the electronic interface with buttons (green and red),
pressure level indicator lights (five levels), battery level indicator lights (three lev-
els) and warning indicator light.
The sprayer has 5 pressure levels, where the leftmost light indicates the lowest
pressure and rightmost light indicate the highest pressure. The resulting pressure
at the end of the nozzle will depend on the selected nozzle.
The battery level indicator has three levels:
•
Three lights on = battery charge higher than 80%.
•
Two lights on = battery charge between 80% and 50%.
•
One light on = battery charge between 50% and 15%.
•
All lights off = battery discharged.
The autonomy of the battery pack (number of hours of spraying with a single
battery charge) depends on the pressure level and selected nozzle (the higher
the pressure, the lower the autonomy). Use this indicator to estimate the battery
autonomy for your spraying condition by checking the remaining battery charge
regularly.

case a faulty condition is detected:
•
Three short beeps repeated every five seconds and warning light is on =
Pump, motor or wiring critical failure. Contact technical assistance.
•
Five short beeps repeated every thirty seconds and all battery level indicator
lights are off = Low battery (only a few minutes left to spray), recharge as soon
as possible.
•
Three lights of the battery level indicator are blinking and warning light is on
= Battery overvoltage (user attempted to connect a battery different from the
original one). If battery voltage is too high, electronic interface will completely
shut-off to avoid permanent damage.
9.9. Turn On/Off the sprayer and select pressure level
To turn on the sprayer and select pressure level:
NOTE: Before starting to spray, make sure all hose fittings are tight to avoid conta-
mination to the operator and the environment.
1.
Install a charged battery pack.
2.
Press Green Button once. Electronic interface will turn on showing all
lights on. Then, the electronic interface will show battery charge status
and pump will turn on in the minimum pressure level.
3.
Direct the spray lance to a safe position and open the trigger valve to
begin spraying.
4.
Press Green Button to choose different pressure levels. When the maxi-
mum pressure level is reached, the pressure setting will return to the min-
imum setting if the Green Button is pressed again.
