5. If the drone won’t be used for a long time, store the drone in a clean, ventilated,
moisture-proof place, avoiding high temperature.
15.Common fault handling instructions
14.1.1. Unstable flying attitude
1. Check whether the screws at the arm and the upper carbon plate are tightened (focus on
checking the arm clamps).
2.
Use a spirit level to check the level of the motor and whether to readjust the level. Standard:
<0.5 degree.
3.
Severe misalignment requires replacement arm
4. Check the condition of the motor, if there is any foreign matter falling into it, and there is a
feeling of stuck. If the motor is found to be faulty, the power needs to be replaced.
5.
Check if there is a gap in the blade surface. (As long as there are gaps or cracks, the blades
need to be replaced)
14.1.2. Tank Leaking
1. Check whether the sealing cap and check valve are installed on the top cover of the tank.
2. Check whether the outlet O-ring and valve seal are installed.
3. Check whether the sealing ring of the bottom cover of the tank is installed and whether the
bottom cover of the tank is flat.
4.
Check whether the tank is damaged and whether the seals are damaged. (If damaged, it needs
to be replaced)
14.1.3. Spraying abnormality
1. Whether there is water leakage in the pipeline, check the PU pipe or hose for rupture, if there
is, replace the corresponding water pipe, if not, check whether the joints are not tight Check
whether the PU pipe of the pneumatic joint is inserted to the end. If not, you need to tighten it
manually and insert the PU pipe to the end.
2.
Make sure that the electric power on the pump can be started normally or not. (The ESC drips
quickly, and then stops after one more drop to indicate that the initialization is complete.)
14.1.4. Working failure handling
What to do if the following faults occur during the operation:
1.
Water cannot be sprayed out before operation: Unscrew the pressure relief valve of any
sprinkler head, turn on the pump switch until the pesticide sprays out, and then tighten the
pressure relief valve.
2.
The nozzle is clogged during the operation: turn off the water pump and land, unscrew the
nozzle and wash it with clean water before reinstalling it to the drone.
3.
In case of not using RTK: during the flight, it is found that the drone's course is not on the
correct course: the drone is landed and the magnetic compass is calibrated.
4.
Unable to unlock and the ground station shows that the accelerometer is not calibrated:
Connect the APP for accelerometer calibration.
