Product safety rules
1.1. Pesticide using specification
A.
Keep away from rivers and nearby water sources when dispensing to avoid pollution.
B.
Pesticides are toxic. Please use them with caution and follow the pesticide use
specifications.
C.
After applying the pesticide, please pay attention to cleaning the skin and cleaning the
drone and pesticide box.
D.
When working, please pay attention to wearing protective equipment to prevent the human
body from directly contacting pesticides;
E.
Try to avoid the use of granules and wet powders, otherwise the service life of the spray
system may be affected.
F.
Please use clean water when dispensing pesticide, otherwise the nozzle will be clogged. If
there is clogging during medication, please clean it up before using.
G.
When taking the pesticide, the liquid concentration, spray rate, altitude of the drone from
the crop, wind direction, and wind speed should be considered in order to achieve the best
results.
1.2. Environmental requirements
A.
Do not fly indoors
B.
Fly at altitudes below 2000 meters.
C.
No one is allowed within the radius of the take-off area from 10m to 20m
D.
There is no electromagnetic interference such as high-voltage lines, communication base
stations or transmission towers in and around the working area.
E.
Always fly within line of sight and stay away from any obstacles, crowds, livestock, water,
etc.
F.
In the North and South Polar Circles, GPS and magnetic compasses will be disabled. At this
time, you can fly in attitude mode
G.
Fly in an environment of 8 ° C to 40 ° C in good weather (not heavy rain, wind,
or extreme weather)
H.
Do not fly in bad weather, such as strong wind (wind speed 5 m / s and above), rain (12
hours rainfall 25 mm and above), snow, foggy weather, etc.
I.
Choose an open space with no tall buildings around it as the flight site.Buildings that use a
lot of steel bars will affect the work of the magnetic compass, and will block GPS and RTK
signals, resulting in poor positioning of the drone and even failure to locate it.
1.3. Pre-Operation inspection
1.
Please calibrate magnetic compass before flying
2.
Short press the battery switch, check the remaining battery power
3.
Ensure that the spray system is non-clogged and functioning
4.
Make sure the landing gear and work box are installed tightly and all screws are tightened.
5.
Make sure the drone motor is clean and undamaged, and there is no stagnation during
manual rotation.
