Propulsion System
To avoid serious injury to yourself or others, which may be caused
by the rotating propellers and motors, observe the following rules:
Propellers
1. Check if the propellers are in good condition before each flight.
Replace aged, chipped, or broken propellers.
2. Power off the aircraft before touching the propellers.
3. Be aware of the sharp edges of the propellers when mounting or
removing the propellers.
4. Make sure that propellers are unfolded and firmly tightened
before each flight.
5. Stay away from the rotating propellers and motors to avoid
injuries.
Motors
1. Make sure that the motors are securely mounted and rotating
smoothly.
2. DO NOT attempt to modify the structure of the motors.
3. DO NOT touch or let your hands or body come in contact with the
motors after flight as they may be hot.
4. DO NOT block any of the ventilation hales on the motors.
1. Keep the motors free of dust.
2. If a motor is stuck and unable to rotate freely, execute the CSC to
stop the motors immediately.
3. Make sure the sound of the motors when powering on is normal.
Spraying System
To avoid component malfunction, serious injury, and property
damage, observe the following rules:
Pesticide Usage
1. Avoid the use of powder pesticide as much as possible and clean
the spraying system after use. Otherwise, the service life of the
spraying system may be reduced.
2. Pesticides are poisonous and pose serious risks to safety. Only use
them in strict accordance with their specifications.
3. Residue on the equipment caused by splashes or spills when
pouring and mixing the pesticide can irritate your skin. Make sure
to clean the equipment after mixing.
4. Use clean water to mix the pesticide and filter the mixed liquid
before pouring into the spray tank to avoid blocking the strainer.
Clear any blockage before using the equipment.
5. Make sure to stay in an upwind area when spraying pesticide to
avoid bodily harm.
6. Wear protective clothing to prevent direct body contact with the
pesticide. Rinse your hands and skin after handling pesticides.
Clean the aircraft and remote controller after applying the
pesticide.
7. Effective use of pesticides depends on pesticide density, spray
rate, spray distance, aircraft speed, wind speed, wind direction,
temperature, and humidity. Consider all factors when using
pesticides, but DO NOT compromise the safety of people, animals,
or the environment in doing so.
8. DO NOT contaminate rivers and sources of drinking water.
Sprinklers
1. Avoid the use of water-insoluble pesticides as much as possible.
2. The sprinklers are delicate parts. Clean them immediately after
use.
3. DO NOT bend the hose in an arc tighter than its minimum bend
radius. This is to avoid creasing, which may compromise the
spraying effect.
4. Make sure to securely tighten the hose nuts to avoid liquid leakage.
6
Spray Tank
1. Make sure that the spray tank is firmly in place to avoid liquid
leakage.
2. The spray tank load must not exceed the specified max value. Refer
to the specifications of each aircraft model for more information.
FPV Gimbal Camera
1. Precision elements in the gimbal may be damaged by a collision or
impact, which may cause the gimbal to function abnormally.
2. DO NOT apply external force to the gimbal after the gimbal is
powered on.
3. DO NOT add any extra payload to the gimbal as this may cause the
gimbal to function abnormally or even lead to permanent motor
damage.
Binocular Vision System
1. The performance of the binocular vision system is affected by light
intensity and the patterns or texture of the surface being flown over.
Operate the aircraft with great caution in the following situations:
a. Flying over monochrome surfaces (e.g., pure black, pure white,
pure red, pure green).
b. Flying over highly reflective surfaces.
c. Flying over water or transparent surfaces.
d. Flying in an area where the lighting changes frequently or
drastically.
e. Flying over extremely dark (< 10 lux) or bright (> 10,000 lux)
surfaces.
f. Flying over surfaces with repeating identical patterns or textures or
with particularly sparse patterns or textures.
2. Keep the cameras of the binocular vision system clean at all times.
3. Make sure that there are clear patterns and adequate lighting in the
surroundings since the binocular vision system relies on images of
the surrounding environment to obtain displacement data.
4. The obstacle sensing function of the binocular vision system may not
work properly when the aircraft is operated in a dim environment or
over water or surfaces without a clear pattern.
Radar Modules
To avoid component malfunction, serious injury, and property
damage, observe the following rules:
1. DO NOT touch or let your hands or body come in contact with the
metal parts of the radar module when powering on or immediately
after flight as they may be hot.
2. Maintain full control of the aircraft at all times and do not rely
completely on the radar module and DJI Agras app. Keep the
aircraft within VLOS at all times. Use your discretion to operate the
aircraft manually to avoid obstacles.
3. The effective detection range is 1.5-50 m. Note that the aircraft
cannot sense obstacles that are not within the detection range. Fly
with caution. The effective detection range varies depending on
the size and material of the obstacle. When sensing objects such
as buildings that have a radar cross section (RCS) of more than -5
dBsm, the effective detection range is 50 m. When sensing objects
such as power lines that have a RCS of -10 dBsm, the effective
detection range is approximately 30 m. When sensing objects such
as dry tree branches that have a RCS of -15 dBsm, the effective
detection range is approximately 20 m. Obstacle sensing may be
affected or unavailable in areas outside of the effective detection
distance.
4. When sensing objects such as an inclined line, inclined utility pole,
or power line at an inclined angle against the flying direction of
the aircraft, the radar detection performance will be affected since
most of the radar electromagnetic waves are reflected to other
directions. Fly with caution.
