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 the 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 an environment with a temperature between 0℃and 40℃.
It is recommended to fly in an environment with a 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 worn
or damaged, please replace them before the 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 intact and firmly mounted, the propellers
and arms 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 the flight.

4. Operation
Keep away from the rotating propellers and motors.
When folding the drone, avoid crushing and damaging the drone parts.
Do not exceed the take-off weight of 78.8Kg to avoid danger.
Pilots must be professionally trained and pass the assessment, and the
untrained personnel must not fly the drone.
Make sure that the propellers are removed before calibrating the drone
and upgrading the firmware.
When the drone and the remote controller are in the frequency-connecting
process, make sure that the propellers are removed and that people and
animals are far away from the motor.
A pilot should not operate this product under the influence of alcohol,
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 using 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 control of the drone throughout the process and do not
rely entirely on the information provided by the hand-held ground
station(remote controller).
Obstacle avoidance and terrain following functions will not be available in
the specific flight mode or 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 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 include but are not
limited to the 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:
Do not fold the antenna during the flight to avoid obstruction between the RC
and the drone, otherwise, the signal quality will be seriously reduced.

1.1.4. RC Charging
1. AC power supply 100-240V 2. USB charger 3. USB-C cable
Attention please:
1. Please use the Type-C interface to charge the RC.
2. Fully charged for about 3.5h with the designated quick charger.
3. Please use the official charger when charging the RC. If not, it is
recommended to use an FCC/CE-compliant, 5V 2A charger or a 9V 2A
fast charger that complies with the QC2.0 protocol.
4. To ensure the best condition of the battery of the RC, please make sure to
fully charge the RC every 3 months.
5. If the RC is found to have a peculiar smell, smoke or liquid leakage, etc.,
stop charging and send it back for inspection and identification in time.
6. Do not charge the RC when the ambient temperature exceeds 60℃.
7. Keep the RC away from infants’ and toddlers’ reach while charging. It is
recommended not to leave it unattended.
1.1.5. Frequency-pairing Instruction
If the user purchases the drone as a whole set, the RC transmitter and the
drone have been frequency-paired 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 RC parameter adjustment assistant, as shown below

©2022 Topxgun (Nanjing) Robotics Co., Ltd. 11
2. Click the “Start Pairing” button, the indicator light of the RC will be flashing
green . APP shows a pop-up of “frequency pairing” and there is a 30s time
limit to turn on the RC. The receiver turns from green flashing to solid
green, and the RC will quickly beep 4 times to show frequency pairing is
completed.
3. Use a sharp tool (e.g. a pen, etc.) to press the frequency pairing button on
the airborne terminal for 3s and release it to complete the frequency
pairing. After the pairing is completed, the RC indicator will be solid green.
If the frequency button is not pressed within 30s, “Frequency Pairing
Failed” will be displayed.

©2022 Topxgun (Nanjing) Robotics Co., Ltd. 12
Notes:
1. Keep the distance between the RC and the receiver within 1m while
pairing.
2. Ensure the propeller is removed from the drone during frequency pairing,
and keep a safe distance from drone motors.

Notes:
1. Activate the battery only after it is well connected to the drone.
2. Disconnect the battery after it is turned off.
3. Charge the battery to 60% every 3 months to ensure a longer service
lifetime.
4. Before using, ensure sufficient battery level. When the battery has not
been used for a long time, please use the dedicated charger to discharge
the battery to the storage voltage, and then store it in a dry and ventilated
environment.
5. This battery needs to be charged with a dedicated charger (TC7202). In
order to avoid accidents, please do not change the charger in any
condition.
6. Do not use batteries if they emit odors or heat, or they are in an abnormal
shape/color or has any other problems. If the battery is in use or charging,
it should be immediately removed from the drone or charger. Stop using
this kind of battery.
7. It is normal that the flight time will be shortened when the ambient
temperature is lower than 10℃.
8. The battery surface should be cleaned in time after the operation, in order
to avoid agrochemical corrosion.
9. The drone is strictly forbidden to be used in the environment of strong
static electricity, magnetic field or high voltage power line.

10. It is strictly prohibited to pierce the battery case with nails or other sharp
objects, or to hammer or step on the battery.
11. If the electrolyte enters eyes after the battery leaks, rinse the electrolyte
out instead of rubbing the eye. Seek medical help immediately. Eyes will
be injured if not treated in time.
