Flight Condition Requirements - DJI AGRAS T20 Manual Del Usuario

2. Make sure to remove the battery from the aircraft during
transportation.
3. Remove or empty the spray tank during transportation or when not
in use to avoid damaging the landing gear. Store the aircraft in a
cool dry place.
Maintenance
To avoid component malfunction, serious injury, and property
damage, observe the following rules:
1. Clean all parts of the aircraft daily and immediately after spraying:
a. Fill the spray tank with clean water or soapy water and spray the
water through the nozzles until the tank is empty. Repeat the step
two more times.
b. Detach the spray tank and spray tank connector to clean them.
Remove the spray tank strainer, nozzle strainers, and nozzles to
clean them and clear any blockage. Afterwards, immerse them in
clean water for 12 hours.
c. Use a water-filled spray washer to clean the aircraft body and
wipe it with a soft brush or wet cloth before cleaning water stains
with a dry cloth.
d. If there is dust or pesticide liquid on the motors and propellers,
wipe them with a wet cloth before cleaning water stains with a
dry cloth.
e. Store the cleaned aircraft in a dry environment.
2. Wipe the surface and screen of the remote controller with a clean
wet cloth that has been wrung out with water daily after operations.
3. Inspect the aircraft every 100 flights or after flying for over 20 hours:
a. Check for and replace worn propellers.
b. Check for loose propellers. Replace propellers and propeller
washers if needed.
c. Check for aging plastic or rubber parts.
d. Check for poor atomization of the nozzles. Clean nozzles
thoroughly or replace them.
e. Replace nozzle strainers and the spray tank strainer.
4. Clean intake vent in the front of the aircraft upper cover after
flying between 50 and 100 hours, depending on the operating
environment.
5. DO NOT attempt to repair the aircraft. Contact DJI Support or a DJI
authorized dealer if any parts are damaged.
1. Keep the protective cover of the radar module clean. Clean the
surface with a soft damp cloth and air dry before using again.
2. Keep the FPV camera clean. First remove any larger pieces of grit
or sand then wipe the lens with a clean, soft cloth to remove dust or
other dirt.
3. In the event of a crash or collision, make sure to thoroughly inspect
every part of the aircraft and make any necessary repairs and
replacements before your next flight. If you have any problems or
questions, contact DJI Support or a DJI authorized dealer.

Flight Condition Requirements

Weather Conditions and Surrounding Environment
The aircraft is designed to operate in good to moderate weather
conditions. To avoid collision, serious injury, property damage or
imposing health hazards, observe the following rules:
1. DO NOT use the aircraft in adverse weather conditions such as
winds exceeding 28 kph (17 mph), heavy rain (precipitation rate
exceeding 25 mm (0.98 in) in 12 hours), snow, or fog.
2. To prevent health hazards to nearby people and to ensure
effective spray, operate the aircraft to spray in wind speeds below
18 kph (11 mph).
3. Keep the aircraft at least 10 m (30 ft) away from obstacles, people,
animals, buildings, public infrastructure, and bodies of water when
in flight. As the aircraft's altitude increases, keep an even further
distance away from the aforementioned objects or obstacles.

4. The recommended maximum operating altitude is 2 km (6,560 ft)
above sea level. DO NOT fly over 3 km (9,842 ft) above sea level.
5. Once the operating altitude reaches 1 km (3,280 ft), the payload
capacity of the spray tank is reduced by 2 kg. For every additional
km, the payload capacity will be reduced another 2 kg.
6. DO NOT operate any part of the aircraft indoors.
1. Aircraft and battery performance is subject to environmental factors
such as air density and temperature.
a. Be careful when flying 2 km (6,560 ft) or more above sea level as
battery and aircraft performance may be reduced.
2. DO NOT use the aircraft near accidents, fire, explosions, floods,
tsunamis, avalanches, landslides, earthquakes, dust, or sandstorms.
3. In low temperature environments (between 32° and 50° F (0° and
10° C)), make sure that the flight battery is fully charged and be
sure to reduce the payload of the aircraft. Otherwise, it will affect
the flight safety or a takeoff limit will occur.
Interference with Flight Controller and
Communications
1. Fly in open areas. Tall buildings, steel structures, mountains, rocks, or
forests may affect the accuracy of the on-board compass and block
both GNSS and remote control signals.
2. Avoid using wireless devices that use the same frequency bands as
the remote controller.
3. The sensitivity of the radar module may be reduced when operating
several aircraft within a short distance. Operate with caution.
4. To avoid interference between operations, do not operate more
than three groups within a 50 m radius when using the Multi-Aircraft
Control function. Unless you are using the T20 with a DJI D-RTK 2
Mobile Station, it is necessary to manually configure the serial number
of each remote controller in DJI Agras.
5. Be alert when flying near areas with magnetic or radio interference.
These include, but are not limited to, high voltage lines, large
scale power transmission stations or mobile base stations, and
broadcasting towers. Failing to do so may compromise the
transmission quality of this product or cause transmission errors
which may affect flight orientation and location accuracy. The aircraft
may behave abnormally or go out of control in areas with too much
interference.
6. If the RTK dongle is used for field planning, the module should be
disconnected from the remote controller after planning is completed.
Otherwise, it will affect the communication performance of the remote
controller.
Operating the Aircraft Responsibly
To avoid component malfunction, serious injury, and property
damage, observe the following rules:
1. Make sure you are not under the influence of alcohol, drugs, or
anesthesia, or suffering from dizziness, fatigue, nausea, or any
other conditions, whether physical or mental, that could impair your
ability to operate the aircraft safely.
2. DO NOT stop the motors mid-flight unless in an emergency
situation where doing so will reduce the risk of damage or injury.
3. Upon landing, power off the aircraft, and then power off the remote
controller.
4. DO NOT drop, launch, fire, or otherwise project any dangerous
payloads on or at any buildings, persons, or animals, or which
could cause personal injury or property damage.
1. Make sure you have been sufficiently trained and have contingency
plans for emergency situations or for when accidents occur.
