VI. Operation of the Sprayer
Charging Before charging, please confirm whether
the charger input parameters are consistent with the
mains supply. If not, please contact the dealer.
The battery of the sprayer has been charged upon
delivery. Due to self-discharge in the process of
transportation and storage, you are suggested to
check the voltmeter before operating. If the indicator
is in yellow or red area, a re-charging is suggested.
When the charge indicator moves to green area, it
indicates the battery has been fully charged.
Note: please use the charger provided by the
manufacturer to charge The Sprayer
Voltmeter The Sprayer is equipped with a
high-precision voltmeter with the voltage indication
range between DC11V~15V. The green area of the
dial indicates that the battery has been fully charged for
normal operation; the yellow area indicates that the
voltage is insufficient but still capable of further
operation; the red area on the left side indicates that
the voltage is seriously insufficient and needs to be
charged immediately. The scale and value above the
color scale indicates the percentage of the battery's
current capacity to that of full charge. If the sprayer has
been used for a short time, it’s not necessary to charge
after every use. If it is put idle for a long time, a regular
(every one or two months) full discharging followed by
full charging is suggested.
Refilling of chemical Prior to each spraying
operation, remove the spray tank cap and fill the tank
with prepared chemical solution through the filter,
followed by replacing and tightening the tank cap
Notes:1. Trial spraying with clean water and checking
various joints for possible leakage are required prior
to initial operation. Make sure everything is ok before
starting spray operation.
2. The sprayer should not be submerged
directly into the water to fetch water or clean.
Power switch Press the red button next to the
charging port and voltmeter to power on/off the
pump.
Note: 1.The sprayer is designed with overload
protection function. While the power switch is
activated, the pump will stop working by itself once
the spray gun shut-off is at OFF position or the
nozzle is blocked. While the spray gun shut-off is
switched to ON position , the pump will start
operation by itself.(The automatic start/stop system
is only applicable when the battery power exceeds
50%)
2. If the Sprayer is put idle for a long time,
the power switch should be turned off in time.
Pressure regulator The working pressure of the
pump may be varied depending on the nozzle and

the object of application, so as to improve the size
of spraying droplets.
The pump pressure may be varied between 0 to
10 bars. Rotate the pressure regulating knob
clockwise to increase; and anticlockwise to
decrease the pressure.
Pressure gauge Display the working pressure of
the pump.

fogging angle, finer fog droplets, and wider
spraying width; loosening to nozzle to obtain
smaller fogging angle, larger flow rate, and
longer spraying distance.
VII. Cleaning and maintenance
After each application, the sprayer should be cleaned to prevent the
corrosion or blocking of the sprayer by pesticides, meanwhile avoid
mixing of chemicals of different varieties between the residual liquid of
this and next applications, which may adversely affect the application
performance or cause harm to crops.
Clean the external surface of the sprayer with a wet cloth. Fill the
tank with clean water and start the pump to spray
until the sprayed water becomes clean. The
remaining water in the spray tank can be
discharged through the water outlet.
Outlet Rotating the drain nut to discharge the
residual liquid or cleaning water. After cleaning,
re-tighten the drain nut.
Cleaning of Filter Rotate anticlockwise to
remove the transparent housing before pulling out
the strainer for a rinsing with water.
Note: When there is chemical in the spray tank,
the chemical may flow out in the process of
removing filter housing.
VIII. Storage

boom to be 5 ~ 10 degrees, and the spacing between nozzles on the spray
boom to be 0.5m.
2. Prior to operation, a trial spraying with clean water for possible leakage
at various connection points is required. Rotate the pressure regulator to
3bar (Extra-high working pressure may lead to spray drifting and
extra-wearing of nozzle). Turn off the power switch after confirming that the
sprayer is in good condition.
