Safety operation instructions
1. Pesticide Usage
Wear protective clothing to prevent direct body contact with the pesticide
while operating.
Avoid the use of powder pesticides as much as possible or else they may
reduce the service life of the spraying system.
Use clean water to prepare the pesticide to avoid blocking the strainer. Do
not remove any filter and clear any blockages before using the equipment.
After using the pesticide, please clean up the residual liquid in time. It is
strictly forbidden to pollute the river and drinking water source, and ensure
that it will not cause harm or impact on people, animals and the
environment in the surroundings.
The effect of the pesticide is closely related to the concentration of the
pesticide, the spraying rate, the altitude of the drone from crops, the wind
direction, the wind speed, etc. The above factors should be taken into
account comprehensively when using the pesticide in order to achieve the
best effect.
Strictly follow the safety instructions of pesticide production company.
Particular working fluids are prohibited.
2. Usage Environment
Always fly in an open space, away from the crowd.
It is recommended to fly below 2000 meters.
It should fly in the environment with the temperature between 0℃and
40℃.
It is recommended to fly in an environment with the wind speed below level
4.
It is strictly forbidden to fly in rain, fog, snow or other extreme weather.
It is strictly forbidden to fly indoors.
It must fly in a legal area. Before flying in the legal area, please consult
your local flight management department to comply with local laws and
regulations.
3. Pre-flight Inspection
Make sure that every device is fully charged.
Make sure that all parts are in good condition. If there are some parts that
are worn or damaged, please replace them before flight. Make sure that
the landing gear and the tank are tightly mounted and all the screws are
firmly tightened.
Make sure that the propellers are not broken and firmly mounted, the
propellers paddle and arm are fully extended, and the screws are
tightened. Make sure the motors are clean and free of damage.
Make sure the spraying system is free of blockage and works properly.
Please calibrate the compass before flight.
4. Operation

©2020 TopXGun (Nanjing) Robotic Ltd,.Co Copyright owner 3
Keep away from the rotating propellers and motors.
When folding, be sure to pay attention to the crushing danger.
Be sure to fly under the take-off weight of 58.90KG to avoid danger.
Operators must be professionally trained and pass the assessment, and
the untrained personnel must not fly the aircraft.
Make sure that the propellers are removed before calibrating the drone
and upgrading the firmware.
When the drone and the remote controller are in frequency-connecting
process, make sure that the propellers are removed and that human and
animals are far away from the motor.
A pilot should not operate this product in poor condition such as after
drinking, fatigue, illness, etc.
If the operating environment does not meet the working condition of the
radar module, the drone will not avoid obstacles when it returns
automatically. If the remote-control signal is normal, the flight speed and
altitude can be controlled by the remote controller.
When working, be sure to turn on the remote controller first, and then turn
on the power supply. After landing, turn off the power supply first and then
turn off the remote controller.
Please maintain the control of the drone throughout the process, and do
not rely entirely on the information provided by the hand-held ground
station.
Obstacle avoidance and terrain following functions will not be available in
the specific flight mode or flight environment. Please observe the attitude
of the drone at all times and judge the flight condition reasonably to avoid
obstacles in time.
5. Flight Restrictions and Local Laws
Browse the official website of the Aviation Authority of your location for the
latest list of restricted flight areas.
The maximum control flight altitude is below 20 meters. Please consult the
local flight management department before taking off, to comply with local
laws and regulations.
Special precautions: Safety operating instruction notes includes but not
limited to above items.

1.1.2. Antenna placement
The antenna of the RC adopts a foldable design, and the signal strength varies with the
positions of the antenna. It is recommended to keep the antenna vertical to the ground
when you control the drone. In this case, the signal is the strongest. The position or
distance between the RC and the drone is adjusted in time to ensure that the drone is
always in the optimal communication range. Therefore, the antenna of the RC should not
point to the drone during the flight. The recommended operation is shown in Figure 1-1-3.

Notes:
1. Do not fold the antenna during the flight to avoid obstruction between the remote
controller and the drone, otherwise the quality of signal will be seriously reduced.

1.1.5. Frequency-matching Instruction
When the complete set of drone is purchased, the remote control transmitter and the
drone have been frequency-matched before dispatching, and can be used directly after
power-on. In other cases, use the following methods to match the frequency:
1. Turn on the remote control parameter adjustment assistant, as shown below
2. Click the "Start Frequency Matching" button, the indicator light of the remote control
will be light green flashing. APP shows a pop-up of “frequency matching” and there is
a 30s time limit to turn on the remote control. The receiver turns from green flashing
to solid green, and the remote control quickly beeps for 4 times to show frequency
matching is successful.
3. Use a sharp tool (e.g. a pen, etc.) to press the receiver's Frequency Matching button
for 3s and release it to complete the frequency matching. After successful
matching , the remote control indicator indicator will be solid green. If the frequency
button is not pressed within 30 seconds, “Frequency Matching failed”will be
displayed.

©2020 TopXGun (Nanjing) Robotic Ltd,.Co Copyright owner 13
Notes:
1. Keep the distance between the remote control and the receiver within 1 m when
you are matching frequency.
2. Ensure the propeller of the drone is removed during the frequency matching, and
keep livestock and human away from drone motors.

the remaining capacity from
high to low.
The charger will sort the batteries
according to the remaining
capacity from high to low, and
can charge two batteries with
higher power at the same time.
Slow charge
The charger automatically divides the batteries into two groups, and
each group will be sorted according to the remaining capacity. The
charger will charge the batteries with low remaining capacity first,
when the battery has the same remaining capacity as the ones in
another group, then two groups will be charged simultaneously
until the end of charging.
