should clear cartridge or keep a certain interval time。
Spraying shall be carried out in windless sunny day, don’t spray under high
temperature at noon. While breezing, the operator should be standing above the wind
and spraying; do not work when wind is four.
When spaying ,if you feel uncomfortable ,headache or dizzy, please leave the site at
once and rest. If once severe symptoms occur, immediately be sent to hospital.
Pesticide effect and the solution concentration, spray rate ,copter high from
crops ,wind direction, wind speed and so on are close related. When using pesticide
should consider the above factors, to achieve the best effect. Please make sure that
do not damage the human beings and animals and surroundings during the process of
sprayings.
When using pesticide , do not pollute river and drinking water

buildings, high-voltage wires and others. Please fly the drone in a dedicated space.
Please ensure the drone fly within the operator’s eyesight.
The drone working temperature is between 0℃-40℃.
Ensure the drone fly within the permit of local law and regulations.
To fly the drone safely as required, please fly it within in the height of 50 meters. If it
has local flying height limit within 5ometers, please make sure obey the related
regulations.
1.5 Operation
Please ensure the multi-rotor drone flying height is within 8 meters, except the special
requirements.
Before remote control calibration、hardware update, parameter setup, please remove
the propellers and avoid the potential moving suddenly.
Remove the battery if it does not fly, to avoid flying it when touching the remote control
once.
Please remove the batteries once landing. Do not move the drone when it is in power.
Do not touch the joy stick mistakenly, and prevent start the drone.

Compass has to be calibrated before using the first time. If else, it cannot work and will
affect flying safety. Calibration tips:
Please do not calibrate it in the place close to the high-magnetic field or big metal
materials, such as high-voltage, magnet, parking lot, concrete iron building, etc.
When calibrating, please do not bring the magnetic materials, such keys and
cellphone.
If it is calibrated indoor, please do not re-calibrate it outdoor. It prevents that the two
magnet differences cause the potential flying data errors.
Magnetic field location is different, please make sure re-calibrate when it changes to
the place far away from the previous one.
