5%) due to chemical corrosion, thick pesticides, replacement of peristaltic pump parts, etc.
Calibration needs to be done with clean water or pesticides used in operation. In case the health
index remains unusual after calibration, check whether the peristaltic pump tubes or spray tubes
are in good condition. Replace them in time if they shrivel, lose their elasticity or are out of
shape.
(1) Impeller Pump
①Open the impeller pump, check the wear between the impeller and frame, replace them in time
if they damage.
②Check if the pump connectors have come loose or oxidized, etc.
(2) Tank
①Check the sealing ring of the liquid inlet.
②Unscrew the cap and check if the inner tubes are in good condition.
③Unscrew the filter and clean the dirt off it.
D. Power System
(1) Battery
①If the battery is not used for an extended period, charge and discharge it every three months to
keep it active.
②When the battery is swelling, leaking, deformed, or having exterior damage, immediately stop
using it.
③Do not charge the battery in a damp environment.
④Do not insert or remove the battery when it is turned on, or its socket could be damaged.
⑤Handle the battery with care. Never take it apart without permission.
(2) Power Socket
With dust, liquid, or other foreign objects sticking to the power socket, poor contact, short circuits
or sparking could occur in the connection of the battery, charger or socket. Before and after the
use of the power device, users should check and clean each component including the battery
plug and socket, ensuring that the power socket remains clean, dry and free of foreign objects.
Transportation
Propeller blades of the aircraft should be folded and fastened by clamps for transportation. Loop
the safety belt through the handles of the drone frame mounting brackets to fasten the aircraft on
the carrier.
